Technical Communication With the advent of IPv6, the unique Internet address is currently almost unlimited for all practical purposes. Therefore, how to apply them is not yet fully defined, but in short, the word "smart" will play a key role.

For example, smart homes will present an ideal environment for addressable nodes; each device in the home is likely to become 'smarter' in the near future, and this means that our home will also become smarter.

The idea of ​​remotely managing the home environment is still just a beginning. Conceptually speaking, you don't even have to manage affairs in the traditional sense; your family will be able to make decisions on your own. Mainly manifested as: intelligent lighting, security systems that identify personal identities, or environmental settings that adapt to the season, time of day, and occupancy. All of this will be possible, thanks to the powerful support of the microcontrollers, which collect and exchange data over the secure channel through wireless communications.



evolution of the number of wireless technology for decades, wireless communication technology has been used to facilitate control of industrial environment; for a long time before the emergence of cellular technology, the times GHz bandwidth in the past (still) mainly for Create a proprietary and robust RF link that has both good coverage and flexibility. However, it can be said that the recent 'open' wireless technologies working in the 2.4 GHz bandwidth range have promoted innovation, and the number of relevant protocols launched at the same time is also numerous. Today, protocols dedicated to wireless communications using the 868.0-868.6 MHz (Europe), 902-928 MHz (North America), and 2400-2483.5 MHz (Global) bands are commonly referred to as the IEEE specification of IEEE 802.15.4 and currently include a series of higher levels. Protocols such as ZigBee, Bluetooth, and threading protocols.

Continuous innovation has allowed manufacturers to drastically reduce the power consumption and size of RF-enabled microcontrollers for the IEEE 802.15.4 standard. As a result, it is now expected to provide the basic building blocks for smart appliances to connect to home gateways. , and from now on connect to the entire Internet. In this way, the homeowner can quickly monitor and control these smart appliances from anywhere, and the gateway can gain certain autonomy in controlling the family environment.

To some extent, the vision of this smart home will be realized through the deployment of smart electricity meters, which can more closely monitor the delivery of utilities such as natural gas, water and electricity. In the Smart Link environment, combined with the appliances responsible for consuming these products, the vision of the smart home has apparently taken shape. However, the smarter use of limited resources is only one aspect. In the future, there will be many opportunities to improve the way of carrying out daily activities, including security access control. The currently available 'Smart Lock' can be programmed using personal code to help homeowners understand the situation at home, including who is at home and at home, etc.

Smart homes will be implemented with a large number of sensors, controlled and connected through low-غير مجاز مي باشدt, ultra-low-power microcontrollers. This is a great opportunity for OEMs in this exciting and potentially profitable new area.

Integrated Solutions

although still low-level protocol IEEE802.15.4, but higher-level protocols but varied and different, device implementation of these agreements as well. For example, the JN516x family of wireless microcontrollers from NXPS Semiconductors integrates a proprietary 32-bit RISC core and a wireless transceiver with a 2.45 GHz radio, modem, baseband controller, and security coprocessor, and one that is in need of a larger range When used to directly control the dedicated output of an external power amplifier.

The security coprocessor provides the hardware-based 128-bit AES-CCM mode required in the IEEE 802.15.42006 standard, while the transceiver block provides MAC and PHY functions controlled by the protocol stack running on the CPU, as well as advanced protocols and application software.


Although the modem provides all the necessary modulation and spreading functions required by the digital transceiver to comply with the IEEE 802.15.4 standard at 250 kbit/s, the baseband processor provides all timing-critical functions of the MAC layer, using dedicated hardware to ensure the air interface. Accurate timing. This hardware/software partition allows the software to implement the sequence of events required by the protocol to schedule timing events in millisecond resolution, while the hardware can implement specific events with microsecond timing resolution. The software may handle higher layer functions of the protocol, for example, using the services provided by the baseband processor to send management and data mesغير مجاز مي باشدes between endpoints and coordinator nodes.

The security coprocessor can be accessed by application software to perform encryption/decryption operations. The hardware-based implementation of the encryption engine can greatly speed up the process. In addition, the JN516x has twenty general-purpose digital I/O pins and two dedicated digital outputs.

Another example of the future system on line SiliconLabs FIG

highly integrated wireless chip launched using ARMCortex-M3 core EM358x series.


The series also has a 2.4GHz, IEEE802-15.4-compliant transceiver. According to Silicon Labs, this series uses an efficient architecture that exceeds the dynamic range requirements of the IEEE standard by more than 15 dB. The use of integrated receive channel filtering means that devices using this family of SoCs can coexist with other devices using the 2.4GHz range; this is an important factor for smart homes because for many, if not all, home appliances, the expectation is that Start wireless function.

It integrates many MAC functions, AES128 crypto accelerators, and automatic CRC processing in hardware, including automatic ACK transmission and reception, automatic back-off delay for transmission, and evaluation of idle channels, as well as automatic filtering of received packets. The Ember packet trace interface is also integrated with the MAC to capture all data packets in and out of the device in a complete, non-intrusive manner and is specifically used with the Ember development tools.

The two series of wireless MCUs described here are specifically developed and positioned for implementation of the ZigBee protocol, which has been deployed in smart home applications, but the recent threading protocol is expected to result in smart home-based device development due to its unique features. Significant and positive impact. Many SoCs that support ZigBee will also support threads, thus providing a roadmap for developers and OEMs.

Conclusion

smart home will use a variety of technologies, including smart meters, gateways and appliances. Although not all smart homes can be connected wirelessly, with the continuous development of wireless technologies such as ZigBee and threads, a large number of smart appliances will use wireless communication as their primary (if not the only) form of connection to home gateways.

The continued development of IPv6 is the basis of this evolution. It can be said that threading is the preferred protocol in this regard because it was developed specifically for exploiting Internet address extensions. This will enable a variety of end-use applications to connect to the home while generating demand for a range of new devices.

In just a few years, homeowners may be able to ask themselves how they were managing when they couldn't monitor and control all aspects of home from anywhere in the connected world.

First, what is the definition of a false alarm false alarm

present there is no authority in our country generally believed: According to this definition. "Dangerous situation no alarm system alarm signal shall be false alarms", the alarm The system's false alarm rate (in a certain period of time, the ratio of the number of system false alarms to the total number of alarms) is generally above 95%. The definition of false alarms in some Western countries is: “False alarms are actual alarms that do not require* and cause the dispatch of alarm signals, which do not include those due to adverse natural climate and other special environments that cannot be manipulated by alarm companies and users. The alarm signal.” According to this definition, the US UL standard states: “Each alarm system can only have four false alarms per year.”

Second, false alarms caused by equipment failure alarm

product under specified conditions, within a predetermined time, a predetermined function can not be completed, called fail. The types of failures are damaging and drifting.

Damaged failures include all failures of performance and abrupt failures. Such failures are usually caused by the damage of components or poor production processes (such as welding).

Drift fault refers to the fault caused by the drift of the parameters of the components and the supply voltage. For example, too high a temperature will cause a change in the resistance value of the resistor. At this time, the device will perform better or worse. In fact, factors such as ambient temperature, component manufacturing process, equipment manufacturing process, uغير مجاز مي باشدe time, storage time, and power supply load may cause changes in the component parameters and cause drift faults.

Whether it is a damaging fault or a drift fault, it will make the system false alarms. To reduce the false alarms that result from this, efforts should be made from the following aspects.

(1) The production enterprise of alarm equipment must improve the design level and technological level of the product. At the same time as the system design, it must also be designed for reliability, such as redundant design, electromagnetic compatibility design, and three-proof design (moisture protection, salt protection) Fog, antifungal, drift reliability design, etc. On this basis, improve the reliability of product manufacturing processes, such as the strict screening of component quality; strict quality supervision and management of the production process, to ensure that product quality meets the requirements of the relevant standards.

Units or individuals that sell alarm equipment shall carry out strict incoming inspections. The contents of the inspection shall be: certification of product quality inspection; production license of industrial production enterprise or safety certification certificate or production registration approval letter.

(2) The management department shall regularly or irregularly organize inspections and random inspections of the security market, and discover that illegal activities in the production and sale of security product activities shall be handled in strict accordance with the provisions of the “Administrative Measures for the Prevention of Security Technology Products”.

(3) The alarm system construction unit (user) shall clearly require the construction unit to use the products that have been inspected by the authorized testing agencies in the corresponding project documents; the foreign equipment shall use products that have been imported from the regular channels and inspected according to international advanced standards.

(4) In order to ensure the good working condition of the alarm system, a regular inspection and maintenance system must be established. By the way, at present, the maintenance methods of China's alarm system need to be resolved, and it is best to repair the variable-construction unit as the maintenance of a professional maintenance company. This will not only be beneficial to the use of maintenance resources (maintenance personnel, maintenance equipment, maintenance spare parts, etc.) The improvement of the maintenance level, more importantly, can improve the reliability of the security system.

Third, the alarm system design, improper construction caused by improper alarm 1, the system design error caused by improper alarm equipment selection is the key to the system design, and a wide range of alarm equipment, but also have their own characteristics, scope of application and limitations, improper selection It will cause false alarms. For example, the use of seismic detectors close to the source (airfield, railroad) can easily cause false alarms; the use of ultrasonic detectors in places where bats are frequent causes false alarms. This is because bats emit ultrasonic waves; High-frequency sounds, such as ring tones and metal impact sounds, can cause false alarms for single-technology glass break detectors. Therefore, to reduce false alarms caused by improper equipment selection, system designers must be familiar with the principles, characteristics, and scope of application of various alarm devices. And limitations. At the same time, we must also grasp the on-site environmental conditions, climate conditions, electromagnetic field strength, and changes in illuminance in order to select alarm equipment according to local conditions.

In addition to the selection of equipment and equipment, the improper design of the system also manifests itself in the equipment installation location, installation angle, protective measures, and system wiring. For example, when a passive infrared intrusion detector is installed facing an air conditioner or ventilation fan, it will cause a false alarm of the system; if an active outdoor infrared detector is not used for proper sun protection (the sun shield is also best for protection), it is bound to Caused by the system of false alarms; alarm lines and power lines, lighting lines and other strong electric circuit spacing is less than 1.5m, without the protection against electromagnetic interference, the system will also generate false alarms.

2, false alarm caused by improper construction This part of the problem mainly in the following aspects:

(1) No strict construction according to design requirements.

(2) Improperly installed equipment or improper inclination.

(3) Solder joints have vacant welds, burrs, or shielding measures.

(4) The sensitivity of the device is poorly adjusted.

(5) Inspection equipment for construction does not meet the measurement requirements.

The solution to the above problems is to strengthen the supervision and management of the construction process and implement the safety supervision system as soon as possible. This will help improve the quality of the project and reduce the number of false alarms due to construction.

3, false alarm caused by environmental noise As a result of environmental noise caused by false alarm refers to the alarm system in the normal state of operation, from the principle is inevitable, and the fact is not needed, is false alarm. For example, thermal airflow causes false alarms from passive infrared intrusion detectors; high-frequency sounds cause false alarms from single-technology glass break detectors; and ultrasonic sources cause false alarms from ultrasonic detectors. The most effective measure to reduce such false alarms is to use dual detectors (two different detectors detect the “target” at the same time, and the alarm only sends an alarm signal). The current products include: microwave-passive infrared double detector, voice-activated glass broken double detector, ultrasonic-passive infrared double detector and so on. However, some environmental noise detectors are used as a force. For example, rats are in the protection zone; pets move around indoors. To this end, scientific and technical personnel have introduced micro-processing technology into the alarm system so that they have a certain ability to identify and think, and can judge to some extent whether it is an intruder or an alarm caused by environmental noise.

OFweek smart home network intelligence smart speaker of the hot war has been burned from abroad, on July 5, Alibaba Group will release its latest artificial intelligence speaker products in Beijing, formally announced its entry into this area, and before Tencent vice president Liu Chiping also public Said that Tencent's smart speaker products "ear" will be released around August. In addition to the Jingdong “Yao” that had previously entered the market, the smart speaker, this seemingly not new product, once again set off a new wave of competition in the smart home sector.

War flames burned from international to domestic

When it comes to smart speakers, you have to say Amazon. From the time it was officially released in November 2014 to more than two years now, the Amazon Echo smart speaker has been one of the hottest smart home products on the market since its inception. People can use Echo to control their home appliances and purchase through voice. Commodity, inquiry and consultation.

According to survey data from a research institution, about 36 million users in the United States use a voice-operated speaker per month, and this number is still expanding. Since the Amazon Echo was released more than two years ago, sales have exceeded billion.

The huge market has attracted the entry of giants.

At the Google I/O conference held on May 17 last year, Google released GoogleHome and directed Amazon Echo.

On May 9th this year, just one day after Amazon released EchoShow with a touch screen, Microsoft released the Invoke smart speaker jointly built with Harman Kardon at the Build Conference. It has built in the artificial intelligence assistant Cortana that Microsoft has developed for many years.

Immediately afterwards, Google updated GoogleHome and GoogleAssist on Google I/O on May 17. After the new version of GoogleHome upgraded via deep learning technology, it now only requires two microphones (Amazon Echo requires seven microphone arrays). This will enable people to accurately locate the people around them; in addition, GoogleAssistant announced that it will cover more than 100 million devices.

On June 5th, Apple also announced the launch of HomePod, a home smart speaker, which was priced at US9, although Apple’s senior vice president, Phil, emphasized HomePod’s “music cell” in his speech, but also pointed out its intelligent speech interaction (Siri) function, and HomeKit may play a central role in smart home services. At this point, the competition of international giants around smart speakers (actually voice interactive devices) has been fully launched.

Compared with domestic, the action is much smaller. Although Jingdong, Baidu, Tencent, Xiaomi, Cheetah, and other Internet companies are all deploying smart speakers or similar voice interactions, both products and strategies are still in a very “primary” stage. .

Let's take a look at Jingdong, which has the earliest layout and the largest sales volume. In 2015, Jingdong United University of Science and Technology set up Linglong Technology, and at the annual conference, it launched the “Hey” smart speaker. At the recent CES, LingLung Technology has launched two new products: 叮咚TOP and 叮咚2 generation smart speakers.

According to the publicly reported material, as compared with the previous product, the Top has cut out a large number of pronunciation units to compress the volume as much as possible. The reason is that Linglong Technology hopes to see it as a home helper, not a speaker. Currently, users can use it to remotely control smart TVs, query information embedded in the assistant, and obtain services.

Lenovo also released its own smart speakers. At the Lenovo Innovation & Technology Conference in May this year, Lenovo announced that it will invest 10 billion yuan in the smart home sector to build affordable products for the common people and showcased a “talking” smart speaker on the scene, both in terms of appearance and function. Both tried to live with the local Echo.

More companies are still in the layout and development stage. In February of this year, Baidu purchased a wholly-owned subsidiary, Raven Technology, to develop smart home control, and was directly responsible for the newly appointed Baidu President Lu Qi. In April, Tencent announced the launch of AI voice assistant “Tencent Jingle Bell”, which directly targets Amazon.com. Alexa; this same month, went out to ask to announce the withdrawal of the virtual personal assistant, and the intelligent speaker Tichome that will be unveiled in the second half of the year; just recently, the first product of the Orion’s Orion Star AI ecological chain, the Joint Himalayan cooperation The Xiaoya AI speakers released have also been announced, and as far as the author knows, this speaker was introduced a few months later than the pre-release time.

In other words, although almost all players want to be able to become “local Echo”, up to now, there is still no mature product that can compete with Amazon Echo.

The market research organization StrategyAnalytics pointed out that in 2016, global shipments of smart speakers will reach 5.9 million units, which will increase 10 times in 2022 and the market value will reach US.5 billion. Gartner predicts that by 2018, 30% of human-computer interactions will be accomplished through natural language. Perhaps next year will be the decisive year for the development of smart speakers.

What are the hands of the Big Three?

If the history of the development of Amazon Echo in the beginning of the release is reconstructed, technology, scenario applications, and user data are the main barriers to its development.

First of all, at the beginning of the Echo release, Amazon did not overemphasize the so-called "smart speaker" concept, but only when it was a product of a speaker upgrade. Amazon executives including Bezos included this far-end speech recognition. Functional speakers only have very cautious expectations: they just hope that the new experience provided by Echo will make users more willing to make purchases on the Amazon e-commerce website.

After seeing the market performing well, Amazon raised Echo to the height of the company's strategic business, and at this time announced the opening of Alexa. In the process, even access to many third parties was personally handled by Amazon. Echo also entered the mass market from the niche circle of early users, which not only thanks to Alexa's voice recognition technology advantage, but also allows more third-party applications to bring rich applications and value to users. In this process, The continuous accumulation of user data makes Echo more and more useful.

However, the essence behind the debate in the smart speaker is the AI ​​dispute. The frequency of data and calling has a very important role in the "evolution" of an AI product. From this point of view, the Echo model has limitations, although Echo products have sold tens of millions of units, and Amazon Alexa itself is becoming an open platform, but it is based on Amazon's own ecology.

At the recent Google I/O conference, GoogleAssistant announced that its coverage equipment has exceeded 100 million units, and this figure will increase dramatically with more hardware platforms. Even more noteworthy is that Google has begun to apply its latest AI technology deep into GoogleHome. At the same time, GoogleAssistant, which integrates voice and image processing capabilities at the same time, is constantly evolving and “feeding” data. This data comes not only from Google user platform data, but also from various devices such as mobile phones, air conditioners, and refrigerators that access Google Assistant.

Latecomers Apple is the main "sound quality." Apple first emphasized that HomePod is a speaker with superior sound quality that can satisfy your musical pleasure. In fact, it is an intelligent voice assistant. In terms of pricing, Apple also distinguishes it from other products.

This actually gave domestic players who are collectively "replicating" smart speakers a wake-up call: Smart speakers should not only be smart, its basic "sound" function - the part of sound quality is also crucial.

Where are the gaps between domestic adventurers?

Echo and Alexa, the voice assistant behind it, let Amazon fly into the sky, and the idea of ​​smart speakers carrying interactive entrances to smart homes has been recognized. In particular, the four giants in the field, Amazon, Apple, Google, and Microsoft, have already gathered. Uniformly identified the correct direction of the road.

Under such circumstances, how can large and small domestic companies not flock? We hope to become the "Chinese Echo and HomePod" and take a place in the next technological enthusiasm - the best entry point for artificial intelligence.

However, from the current market, there are only a few smart speaker products, there are still many areas that need improvement, such as the speaker sound quality is too general, the voice assistant is very strenuous and so on. However, the Chinese market, which was not taken into account by international giants such as Amazon and Apple, did leave room for domestic players.

To be honest, in fact, it is not necessarily a speaker, but the ecological chain behind the small speakers is more attractive to the giants to get together in this area. After all, voice assistant is one of the most frequently used applications in the field of smart home. Smart voice can be combined with TVs, stereos, air conditioners, curtains, lamps, toys and other home devices and smart home control hub systems to achieve an entrance control all functions through voice interaction. This is also the most convenient interactive way in the artificial intelligence era. one.

At the same time, the promotion of big data and artificial intelligence technologies, the reduction of key technologies and component غير مجاز مي باشدts, and the establishment of industry alliance standardization agreements have brought about a rapid increase in the scale of the smart home market. In the future, it may not necessarily be the form of a smart speaker. It may also be a mobile phone voice assistant, a smart TV, a smart air conditioner, or any other device. The ultimate essence is still the user, data, and services.

Compared with the big data support behind the smart speakers owned by Apple, Amazon, Google and even Microsoft, companies involved in the field of smart speakers in China are basically not in this area have a high voice. Using an easy-to-understand word in the industry to describe the differentiation of smart speaker products at home and abroad is: “Foreign giants have landed smart speakers products because they are considered the best entrance for many services and user data. Domestic companies selling speakers are selling speakers. There is no real service. Most of them are hot spots to be sold as new digital devices other than mobile phones."

Although this kind of comment may not be comprehensive, it is an indisputable fact that domestic companies do not have the status quo of cloud computing + big data service support. Even domestic giants such as Baidu who have exerted frantic intelligence in arranging artificial intelligence may not be able to use the ecological chain. There are basic operating conditions, and Ali and Tencent, Jingdong, etc. have taken a leading role in this area, more like finding a way to provide value-added and incremental services for their core business lines.

It is reported that in Alibaba’s upcoming smart speakers, users can make voice purchases on Taobao and Tmall by issuing corresponding instructions. The built-in voice assistant will display the natural language processing results of Alibaba's technical team for the first time. What is claimed in the public information is that the model's answer rate established by the smart speaker in text classification and intelligent question and answer is currently the highest level in the industry, and even slightly higher than that of Microsoft and IBM, but can it still be a Chinese language department? It's a little bit of expectation to achieve accurate recognition. Tencent executive director Liu Chiping also publicly stated that Tencent is developing a smart speaker “ear” or released around August, but Tencent’s cloud and speech recognition technology can provide transcendental technical support for this smart speaker. know.

Before this, foreign giants could not present the technical support for Chinese phonetic semantics perfectly, leaving a huge market gap in China, which gave domestic manufacturers the best opportunity. However, judging from the information judging by all parties at present, even domestic companies such as Alibaba, Tencent, and JD.com will most likely provide products for their products and work scenarios, and whether they can take their own ecological links. Going to a broader public service is a question.

While Alibaba, Tencent, and Jingdong have all taken this step cautiously, other speculators like the wearables sector who are hoping to get a slice of the hot spot, have no technical, software, data, or service support. Hardware and brand-named "one-and-for-all, one-and-one" games are definitely not suitable for this new field. Although smart speakers are already on their factory's assembly line, they can actually rest for a while, perhaps from a There is no need to be born at the beginning.

The electronic scale needs to be checked every year. What is the specific process and steps? Let's talk about it:

First, pre-test preparation 1. First preheat the instrument for 30 minutes, because the ambient temperature has a great impact on the working environment of the instrument, it is very important to preheat the instrument, especially in the cold northern part, so that the instrument can be The various components are in good working condition and play a good role in making the measurement accurate.

2. Check if the scale body is flexible and if there is any foreign matter stuck. The scale body is flexible, and the weight of the scale body and the force generated by the weight on the scale body will completely act on the sensor and be completely absorbed by the sensor. The sensor can produce accurate signals to the secondary instrument, and the meter can correctly display the weighed indication. If the scale body is stuck with foreign matter, the weight of the scale body and the force generated by the weight of the scale body will not fully act on the sensor, but a force component will be absorbed by the guard edge, and the sensor cannot produce an accurate signal. For the secondary instrument, the meter will not display the weighed indication correctly.

3. Before the weighing test, one load should be preloaded to the maximum weighing. For the weighing scale with the maximum weighing equal to or more than 10 tons, no less than 50% of the maximum weighing vehicle can be used to traverse the carrier no less than 3 Secondly, the purpose is to fully press the force transfer ball of the sensor into the center of the lower head and the center of the upper head, so that the three centers are again in a straight line, so that the weight of the scale body and the weight of the scale body can be increased. The force will be fully applied to the sensor, the sensor can produce accurate signals to the secondary instrument, and the meter can correctly display the weighed value.

II. Inspection of Signs In accordance with the regulations of the JJG539-1997 (Digital Indicating Scale) Certification Regulations, the mark of the loadometer shall have: Mandatory mandatory signs, manufacturer's name and trademark, accuracy rating and symbols, maximum weighing MAX, minimum weighing Quantity MIN, verification division value e, manufacture license mark and serial number, serial number. The sign should be solid and reliable, and the size and shape of the handwriting must be clear and easy to read. The sign should be embodied in the form of a dial, and in a clearly visible place, the paste should be firm. If this item is unqualified, the verifier should request the scale owner to notify the manufacturer of the weighbridge to reissue the relevant content, and may temporarily not perform the verification of the following other items.

Third, the zero test mark after passing the first zero test, zero test is divided into zero point tracking device and the platform with zero point tracking device weighbridge two methods of verification.

1. In weighbridges without a zero tracking device, the loadometer is zeroed first, and then the weight applied to change the indication from zero to the next division is determined. The specific method is: Zero the ground weight, place 0.1e small weight on the ground scale one by one until the value becomes e, according to JJG539-1997 (digital indicating scale) verification procedures 5.2, 4.2

The calculation method calculates the zero error.

2. The weighbridge with zero tracking device, after freeing the indication from the automatic zero and zero tracking range, place a small 0.1e weight on the ground scale one by one until the value becomes I+E, then calculate the zero according to 5.2, 4.2. error. The specific calculation method is:

(1) Place the small weight of 10e on the weighing platform (if with zero tracking), display I=10e.

(2) Adding a small weight △m to the weighing platform until the value is shown by I+E;

(3) Calculate the zero error E0 = I + 0.5e - △ mm, where: I is a numerical value, E is a division value, Δm is an additional small weight, and m is a small weight of 10E.

IV. Partial Load Test 1. Place a weight of m=1/N-1 on each corner of the weighbridge with a corresponding value of I.

2. Add a small weight △m to the weighing platform until the value is shown by I+E.

3. According to JJG539-1997 (digital indicating scale) verification procedures 5.2, 4.2 calculation method to calculate the error of each point:

E=I+0.5e-△mm.

4. Calculate the correction error of each point: EC=E-E0

V. Weighing test 5. Weigh the weights of the minimum weight 20e, 500e, 50% maximum, 2000e, and maximum weight in order from the smallest to the largest.

6. Add a small weight △m to the weighing platform until the value is displayed by I+E.

7. Calculate the error of each point:

E=I+0.5e-△mm.

8. Calculate the correction error EC=E-E0 at each point. Enter the calculation result EC in the record.

9. Remove the weight on the weighing platform from the largest to the smallest.

10. Add a small weight △m to the weighing platform until the value is displayed by I+E.

11. Calculate the error of each point E = I + 0.5e - △ mm.

12. Calculate the correction error of each point EC=E-E0, and fill in the calculation result EC into the record.

VI. Discrimination Test 1. The discriminating power test can be performed simultaneously with the weighing test.

2. Perform a discriminating power test with a minimum weighing of 20e, a maximum weighing of 50%, and a maximum weighing.

3. The specific method of operation:

(1) Add a certain amount of weights and 10 small weights of 0.1d on the carrier, and then remove the small weights, until the value of the indicator I is determined to reduce the value of a fractional ID.

(2) After adding 0.1d small weight, add 1.4d weight, then the value must be I+D.

Repeatability test 1. For the same load, the difference between the results of multiple weighing shall not exceed the absolute value of the maximum allowable error of the weighing.

2. Perform two sets of three repeatability tests in each group at 50% maximum and maximum weighing.

3. Calculate △P, △P=PMAX-PMIN, and fill in the verification record form with the calculated △P value.

Eight, peeling test to determine the accuracy of the peeling device, the value of the use of peeling device should be adjusted to zero, using 5.2,1.2 point test.

For the first verification, at least two different tare weights should be tested for tare weight and loaded and unloaded in accordance with 5.4, 2.1.

The test should at least select the following 5 weighings:

1. The minimum weighing 2. The maximum allowable error to change the weighing; 50% of the maximum weighing;

3. Possible maximum net weight value 4. If the ground loader is equipped with a tare device, a test that approximates the maximum added skin weight should be performed.

5. If the weighbridge has an automatic zero or zero tracking device, it can be run during the test; its zero point error is measured at 5.2, 1.2 points.
