Pay attention to the suitability of choosing ppe

At present, most of the monitoring of building equipment is based on manual inspections. For example, for some equipment that needs real-time monitoring, maintenance personnel are usually placed next to the equipment. Of course, the drawbacks of this model are also obvious. It not only consumes a lot of human resources, but also greatly increases the غير مجاز مي باشدt of monitoring. The current on-line equipment fault monitoring system mostly adopts the acquisition card and PC mode. The acquisition card is responsible for collecting data, and the PC is responsible for data processing and transmission. This kind of system is bulky and expensive, and is not suitable for applications where the production equipment is dispersed and the work environment is harsh. In order to solve these problems, this paper applies intelligent router related technology and Internet technology to the design scheme of equipment monitoring system, making the equipment failure detection system have remote monitoring function.

UPS is an abbreviation for "uninterruptible power system". It is the "heart" part that powers the security monitoring system. It provides an important external equipment for the security monitoring system to provide continuous, stable, uninterrupted power supply. At present, there are a wide variety of UPS power supply devices on the market, and the output power is also different. UPS uninterruptible power supply can be divided into standby type and online type according to the working mode. According to its output waveform is divided into square wave output and sine wave output two. This article describes the working principle of the UPS power supply, and how to configure the UPS power supply of the security monitoring system.

Standby power is one of the basic elements of a security monitoring system. The system that lacks the backup power supply has hidden fatal flaws and cannot be put into practical use, because it is very likely to delay the fighters, stop and lock down, and paralyze the entire system at a critical moment, resulting in irrecoverable losses.

The security monitoring system normally uses 220 volts of utility power, but in the special case of power failure and mains destruction, it should also work for a certain period of time. This requires the use of backup power to maintain the normal operation of the monitoring system during this period of time. Backup power supply has two or more power supply, battery pack power supply, generator power supply, UPS power supply and so on. However, UPS uninterruptible power supply is usually used as backup power source for security monitoring system.

First, the working principle of UPS (uninterrupted power supply)
The UPS power supply consists of a battery, an inverter, a charger, a voltage stabilizer, and a changeover switch. When the utility power is input normally, the UPS will supply the load after the utility voltage is regulated, at the same time, the internal battery pack will be charged, and the energy will be stored in the battery; when the utility power is interrupted (accidental power failure) or the input fault, the UPS will immediately The energy conversion of the battery will continue to be used by the load with 220 volts alternating current, so that the load can maintain normal operation and protect the load hardware and software from damage. UPS power supply is divided into backup, online, online interactive three categories:

1. Standby UPS When the mains supply is normal, the mains supply the power directly to the load via the AC bypass channel via the transfer switch. The inverter in the UPS is in a stop working state. At this time, the UPS power is essentially equivalent to A single-purpose utility voltage regulator. In addition to the improvement in the amplitude fluctuation of the mains voltage, it has basically no adverse effects on the frequency instability of the voltage, waveform distortion, and intrusion from the grid. Only when the mains power supply is interrupted or lower than 170V, the battery will immediately supply power to the inverter and provide the load with a square wave AC voltage with constant voltage and frequency stabilization.

2. When the on-line UPS power supply is powered normally, it first rectifies the mains AC power supply into a DC power supply, and then performs pulse width modulation, filtering, and reconverts the DC power supply into a sine wave AC power supply via the inverter. Power is supplied to the load. Once the commercial power is interrupted, the DC supplied by the battery is immediately replaced by an inverter, pulse width modulation, and filtering to provide a sine wave AC power supply to the load.

Therefore, for on-line UPS, under normal circumstances, whether there is no electricity, it is powered by the inverter of the UPS power supply to the load, thus avoiding all the voltage fluctuations caused by the mains grid and * Impact.

Obviously, the power quality of the online UPS power supply is obviously better than that of the standby UPS power supply because it can achieve stable frequency and stable power supply to the load. Moreover, when the mains is converted to the battery power supply, the conversion time is basically zero, and the user is provided with a pure sine wave power supply with a high-quality stable voltage and frequency stability, thereby providing the power supply protection required by the security monitoring system.

Online interactive UPS power supply combines many advantages of standby UPS and online UPS, and it is also a very good form of transformation. However, because it uses a power frequency transformer, it has a bulky and bulky problem.

Second, how to configure the security monitoring system UPS power supply UPS is the birth of the computer and the emergence of backup power. In the security monitoring system, more and more applications of computer technology, so the higher and higher requirements for power supply quality. UPS can not only comprehensively improve the quality of power supply, but also provide comprehensive protection for the entire system and even network data. It can also ensure the normal operation and operation under the special conditions of mains power failure and human damage. Because the security monitoring system requires higher power supply, it usually chooses on-line (sine wave, mains power) UPS power supply.

When UPS power supply is provided to the security monitoring system, the power consumption of the entire system equipment should be estimated first. The safety factor is generally 1.2-1.5, which is sufficient for the power supply system to have sufficient redundancy. Second, according to the system requirements delay power supply time, calculate and configure the battery pack. Finally, we should pay attention to the use of the environment, moisture-proof ventilation, focus on cooling, to extend the average time between failures and improve the reliability of the system. The UPS power supply should be set up in the monitoring room to implement unified management. When the commercial power is abnormal, it can provide uninterrupted power supply to the system equipment in time to ensure that the system works normally.

Juice Drinks

Fruit juice drinks is a beverage made of fruit juice products obtained by physical methods such as pressing, centrifugation and extraction. Fruit juice retains most of the nutrients in the fruit, such as vitamins, minerals, sugar and pectin in dietary fiber. Often drinking fruit juice can help digestion, moisten the intestines and supplement the lack of nutrients in the diet.

There are two kinds of fruit juice: pure fruit juice and compound fruit juice. As far as pure fruit juice is concerned, it can be divided into two types: one is to directly use the original juice, and the other is to dehydrate the freshly squeezed fruit juice first, and then add water to reduce it into concentrated fruit juice. Most pure fruit juices are concentrated. AGOLYN offers various flavors of honey tea, such as honey Citron tea etc.

As a 95-year-old beautiful girl, there is no point in the bottom of the photo camera APP, how in the ticket circle.

The young girl's favorite is to take pictures, to leave the most beautiful figure in my most beautiful age.

The following APPs will make you look beautiful and not artificial in the era when the revision of the map does not recognize the mother and mother.

As a self-portrait app, B612 is undoubtedly excellent, after all, users who look at it will know.

A lot of beauty filters, compared to a figure Xiu Xiu, I prefer to use it because the filter is more natural beauty, beauty without distortion ah.

(After all, natural beauty is hard to forsake, the overall feeling of a picture is a silicone face)

Then it is its video recording function, divided into 3 seconds and 6 seconds, 3 seconds recording can also be made into WeChat expression package. Now the micro-channel map, the baby is directly using B612 turned a white eye to send in the past. Victory!

There are also a variety of sprouting facial expression shots, as if the self-timer does not have two ears on his head and his face is more than enough to have enough fashion.

As a photo app for the Asian Money Day Group, it is absolutely love for girls who are directed at the line friends.

The biggest highlight of the filter, which is the same as a normal camera, is the large number of stickers it contains, and the stickers are updated quickly. Although most of them are paid, Line Friends stickers are free! Free! Free! (Important things to say three times)

In addition to the function of a brush and a sticker, I also love to put it down. There are many types of brush, in addition to the ordinary brush, flash, stars, love, and still the brush of Line Friends.

This is an app that compares ghosts and animals, and pulls out the portraits in the photos, and then arranges them in order to use them with caution.

Just buckle a picture for you to feel.

The background is replaceable, and there are some cute stickers to choose from, feeling more spoof than beauty.

Of course, the girl's heart bursting APP, style should be the following sauce purple.

The night camera is actually a camera suitable for use in low light conditions. The fairy is not like the baby. In the absence of light, the other cell phone will have a flash and self-timer will give it a shot.

Now you can use it, and immediately go to the next Night Camera. Under a poor light environment, a photo app that automatically fills the light.

Although there is no beauty, but there is no light at night, beauty is useless. Use this app to finish the night scene and then use a picture to grind a skin, thin a face or something, do not have a whitening in the evening! Then use VSCO to adjust exposure, shadow, contrast, and finally add a filter to the United States and the United States.

Although it is a social APP, but I take it as a photo APP, because it is going to wall over, so basically as a social feature has been abolished for me.

And then as a camera, it's not as powerful as it is, but it's a beautiful filter. It is no more than 20 filters, but it looks pretty, in addition to the filter can also adjust the photo parameters, you can also record video.

Like black and white style, I must push this black and white APP.

In addition to the black and white shots that can be shot directly, they can also be post-processed.

The black and white filter you thought was black and white, but in fact there is still stress. Open the Hypocam camera, you can set the squares, exposure, contrast, and so on. The camera's normal black and white filter will help you determine what When black and white filters are more suitable.

Don't you think that black and white photos always give people a big sense of real-time.

This is actually a bit similar to B612, but personally think that Faceu's expression more choices, and follow the trend.

This app is really magical. Since it came down to Faceu, everybody has to take a picture of her and the family's elders have also been played by me.

In addition to the self-portrait of Meng Meng's expression, the expressions of those devil's and ugly's ugly are undoubtedly my favorite.

There are also some expressions that need to be recorded through your actions. For example, if you have a squirting gourd doll before you open your mouth, the screen will show the appearance of gourd dolls, and an expression can be entered by more than one person at the same time. Lens, our highest record is six Spitfire gourds ~~~

The most played online is this spray rainbow!

Finally say a app to shoot food.

Go out to eat is definitely the first to eat mobile phones, remember to see a picture on the Internet, is a dish up, and then a dozen people around the camera, finished eating no one, are in the map.

Self-timer does not shoot well, or about the value of the value of food is good, uploaded to the ticket circle will lead to a variety of goddess goddess of praise.

This Foodie is an app that specializes in making food. It is really easy to take very ordinary food and make it very tasty. Well! It looks very tasty . Home travel essential APP.

Give you a look at the side of the roadside booth that I readily shoot.

According to experts, high-tech products, such as biometrics and electronic technology, are currently in a blank stage in the consumer market of locks. However, the desire of consumers in this area is increasing every year.

The lock-making enterprises have developed IC card electronic door locks, electronic code locks, encrypted magnetic card door locks, floor apartment intercom alarm systems, valve locks, and fingerprint locks. Because the high-end locks have high technical content, more prominent humanity and individualized features, the profits of the products are also relatively high. In addition, with the rapid replacement of lock products, high-end locks will gradually become the mainstream of locks.

A lock may seem simple, but it must be completed through 110 processes. The lock industry is not only a traditional industry, but also has close links with the new and high technologies. Today, with the rapid development of lockmaking technology, advanced equipment and design levels are not mastered. With a group of highly qualified professionals, it is difficult for enterprises to lead in the industry. This year's copper prices have fluctuated and the locks have encountered unprecedented غير مجاز مي باشدt pressures. In the first half of this year, the prices of raw materials such as copper and aluminum rose several times. As the غير مجاز مي باشدt rises, the rising price of the product can not reach one-tenth of the غير مجاز مي باشدt. If the price of the product rises as much as the غير مجاز مي باشدt, the customer will lose. Therefore, business households have stated that the industry urgently needs technology and industrial upgrading to update its brand innovation model. Innovations in the lock industry require companies to change their concepts, change ideas based on imitation, master independent technologies, increase investment in equipment, technology, R&D, and patent innovation, increase product technology content, and increase product differentiation; companies should pay attention to Promote brand awareness and implement brand strategy, so as to change their position, grab high-end market share, and promote the healthy and rapid development of the industry.

At the same time as the smart lock strives for breakthrough, there are also many changes in the mechanical lock. The style of the hardware lock is more and more. With the warming of the real estate and the acceleration of the urban process, the consumer demand of the decorative hardware market is greatly stimulated. Although a small decoration hardware is inconspicuous, but the product function style is more and more optimized and refined, the variety of species, style contests.

There are more and more styles of hardware locks, many of which look more like one or a small animal, but its function is a lock. In the market, the more popular civilian locks are mainly spherical, three-bar type circular cover handles, embedded long cover door locks, and lock body handles. The other trend that is most used in the inner door is the channel and the auxiliary lock (the most important feature of the anti-theft function). The author learned from the market that the currently available locks are mainly brass, stainless steel, and bronze. The treatment of surface color is mainly a combination of two color combinations. In terms of price, the door lock is generally more than 100 yuan, expensive to 800 yuan or more; inside the room lock is relatively cheap, 80 yuan can buy a good lock.

The future development direction of locks in China is:

1. The development of high-end locks The high-end locks have a bright market prospect. Because the high-end locks have high technical content, more prominent humanity and individualized characteristics, the product profits are also relatively high. Should increase investment in high-tech locks and promote the structural upgrading of China's lock industry.

2. The implementation of brand-name strategy lock industry well-known companies and brands can produce huge economic and social benefits, and now China's locks face more severe challenges, competition prompted companies to respond positively, so that China's production from locks to power from a big country.

3. The implementation of diversified development of locks companies to accurately position themselves and the market, the implementation of multiple development. In the so-called field, we design locks that cater to the public and have individual needs, avoiding the fierce competition brought about by similar public locks. In addition, companies must take the road of a diversified market and avoid being affected by a certain factor and affecting the fundamental development of the company.

RFID (Radio Frequency Identification) technology is a non-contact automatic identification and data acquisition technology. This paper proposes a particle filter-based RFID data cleaning method RPFC (RFID-Particle Filter Cleaning), which transforms the raw data into a smooth probability data stream with respect to the location of the tag. It has higher sensitivity and will be better applied to mobile. label.

1, particle filter technology

Particle filter technology is a new tracking algorithm that implements Bayesian filtering. It can effectively deal with non-linear and non-Gaussian tracking problems. It can adapt to overlapping and occlusion conditions in complex environments and can simultaneously track multiple targets. Therefore, it is mostly used. In GPS tracking and other object tracking, personnel tracking. In RFID applications, reader readings are actually inaccurate data streams with non-deterministic semantics that track the location of tags in real time. RPFC is based on the above two points and uses non-deterministic strategies to clean RFID data. .

2, RPFC non-deterministic cleaning framework

For the unreliability and semantic uncertainty of RFID data, this paper proposes an RPFC non-deterministic cleaning framework. The RPFC non-deterministic data cleaning is divided into semantic cleaning and misreading and cleaning. Semantic cleaning mainly solves the problem of semantic non-determinism of RFID raw data, and obtains an effective probability value to express the non-deterministic nature of RFID data through cleaning. Misreading and cleaning mainly solves the problem of negative reading and positive reading of the reader, and ultimately provides a “clean” data table for the upper application.

2.1 Raw data semantic cleaning There is semantic uncertainty in the original RFID data, but the original data description does not express this non-determinism. To a certain extent, it can not reflect the actual situation of the application. To solve this problem, this paper carries out RFID raw data. Semantic cleaning.

2.1.1 Raw Data Semantic Purge Target Raw Data Triplet Descriptive Type For example, where R represents the identifier of the reader, O represents the identifier of the detected tag, and T represents the moment when the reader R detects the tag O.

The RPFC method cleans the original data semantically, converts the reader identifier R in the original reading into a specific application location information L of the tag O, and introduces a probability dimension P to indicate the possibility that the tag O is in a specific application position L. The data is represented by three. The tuple form becomes a quad.

2.1.2 Raw data semantic cleaning strategy The RPFC method uses a weighted particle set to track changes in the position of the label according to the particle filter process to obtain the probability distribution of the position of the label, that is, to obtain the non-deterministic representation of the RFID data and realize the raw data. Semantic cleansing. The specific semantic cleaning strategy of the RPFC method is as follows:

The first step: RPFC sampling, generated according to the position distribution of the tag at time t-1, the particle position conversion model p(Lt|Lt-1) and the particle motion model p(mt|et-1,factort-1) The new particle set St={Lit,wit|i=1,2,...,N}, where N is the number of particles in the particle set and wit=1/N.

The second step: RPFC importance sampling, when the reader generates a reading, according to the new reading T item to calculate particle concentration on the particle at the time T, and according to particle observation model p (zt | Lit) to the particle concentration The particle weighting value.

The third step: RPFC resampling, according to the second step to get the number of particles at each position and the weight of each particle, and the Bayesian formula (such as (1)) to calculate the probability distribution of the label, and according to the ratio Resampling to get a new particle set position distribution, from the straight line uniform motion formula to obtain the particle's motion pattern, and then set t = t + 1, go to the first step. Assuming that the particles are distributed at NL positions, the number of particles at each position Li is Ni, and the weight of the jth particle is wjt and equal to other particle weights at the same position, then the label position probability distribution P ( The formula for Lit|zt) is as in (2).
