Pay attention to the suitability of choosing ppe

If a fire breaks out, the first thing to do is to pass the fire information to the fire safety management department, the person in charge of the unit, the fire brigade, and the personnel to be evacuated. The volunteer firefighters of all units must actively participate in the initial fire. When the fire spreads and the fire deteriorates, it is necessary to promptly call the “119” fire alarm and send special personnel to the junction to welcome the fire engine. The following points should be noted when dialing: 1. Say the details of the fire unit's address, the specific location of the fire; 2. The nature of the burning unit's burning material, such as oil, electrical appliances or cotton fabrics, and buildings; 3. Fire's Size; 4. The alarm person's name and contact information.

Fires at the initial stage of fighting were carried out with the rapid spread of fire, the large number of people, and the complex fire conditions. In the work of organizing and commanding firefighting and self-rescue, we must insist on ensuring the safety of most people. Command must be decisive and action must be rapid. Specifically, we must pay attention to alarm reporting, evacuation and rescue, organization of fire extinguishing, smoke and smoke prevention, explosion prevention, on-site rescue, communication links, logistical support, and security alert.

Self-help commonly used methods are as follows: 1, rope self-rescue method: home with a household rope, one end can be directly on the door, window stalls or heavy objects along the other end climb down. During the process, the feet should be twisted to clamp the rope, hands alternately climb down, and try to use gloves and towels to protect their hands. 2. Ascension method: Since the smoke mostly gathers in the upper space when a fire occurs, the body should be as close as possible to the ground or bent forward during the escape process. 3, towel blowing nose method: fire smoke has high temperature, toxic characteristics, once inhaled it is likely to cause respiratory system burns or poisoning, so evacuation applications wet towel to cover the nose and mouth, in order to play the role of cooling and filtration .

A small door lock not only protects the security of each household in the entire home decoration, but also decorates the home.

From the affluent Lock of AUO BRONZE lock to the good gold handle with more than 100,000 hardware, the jaw-dropping figures are sighing with the improvement of material life. Luxury. Not only the astronomical price of tens of thousands of yuan, but also the function and aesthetics of the door lock have been greatly improved. The door locks have turned from daily necessities to luxury goods. Where are they expensive? What are the options for purchasing and using ordinary home door locks? Let the Information Times reporter lead readers to reveal the “mysterious face” of the lock!

High-end door locks

Bring "Foreign Descent"

Although the door lock is only a piece of hardware in the entire home decoration, this “door general” is crucial, not only protecting the security of every household, but also decorating the home. Compared with ordinary home locks, high-end locks used in luxury homes and high-end business establishments are only more expensive to look at. It is understood that these expensive locks carry “foreign blood lineage” and are designed by well-known foreign designers. They use the most expensive foreign advanced materials and are hand-crafted by experienced craftsmen. They reflect their luxury from design to production. Features.

In the high-end locks, there are many from the master's hand, which also adds a lot of "weight" to the lock. The most special is that almost every famous designer's door lock design is based on a unique inspiration or story. Like a famous Italian designer Tosca. The locks designed by Renelli are inspired by the illustrious Medici family in Europe. They use the European aristocratic style of decoration. The blue and deep colors and generous lines show a profound aristocratic culture. It is very fashionable. In addition, there is a designer Libby. The "Warriors Triumph" door lock designed by Monreale and the texture of the door locks are just like the medals of the Warriors. The designer hopes to use it as a reward for the user. Every day, he can greet the tired and hardworking family and create a comfortable living environment for his family. "warrior".

Ordinary door lock

Affordable features

Although high-end locks are beautiful and luxurious, the price of astronomical numbers is not affordable for all families. Hundreds of dollars of stainless steel, alloy locks are the common choice for most owners. According to Haomeijia building materials supermarket lock sales personnel, popular door lock prices are quite affordable, the price between 100 yuan and 500 yuan, and the quality is guaranteed, is the most economical choice for ordinary people. At present, the types and types of door locks in building materials supermarkets are very rich. The average consumer often has a sensation of picking flowers. The salesperson reminds that the selection of door locks depends on two major elements: material and function.

It is understood that the material used for the hundreds of yuan of door locks used in ordinary homes is mostly made of stainless steel, copper or alloys. From a durable point of view, the best material should be stainless steel, even if those are just stainless steel door locks, do not worry about fading and other issues, but also "more and more light", in addition, the benefits of stainless steel is its strength , Strong corrosion resistance, if it is often the need to switch the door, the best choice for this type of material. The copper material is one of the most widely used lock materials. Its mechanical properties are good, corrosion resistance and processing performance are also good. It is characterized by gorgeous color, often on the surface plated with a layer of beautiful rose gold or silver, it looks grand, Elegant and generous, adding a lot of color to the home. In addition, sales staff also said that the alloy door locks sell the best, the price of around $ 100, the most suitable for use in the room and bathroom kitchen.

In addition, since 2002, the continuous use of new technology in locks has also increased the environmental performance of locks. For example, some imported locks adopt nano-antibacterial treatment technology. The use of electroplating, spraying, coloring, or other processing methods to cover the surface of the locks will not only make it difficult for the bacteria to stay on the locks, but also play a role in anti-corrosion and anti-fading. .

The reason why high-grade door locks are so expensive is that the material itself is very expensive. According to a lock dealer from Yufu Hardware Building Plaza, these high-grade door locks are made entirely from Italian high-quality copper rods, and carefully selected copper rods are also forged by 1,000 tons of forging presses to ensure the door. The quality of the lock material can stand the test.

In order to make the high-end door locks more luxurious, the makers usually also coat the outside of the door locks with a precious metal, such as rare 24K gold or other K gold material, so that the door lock looks more brilliant. According to Mr. Zhou, the person in charge of the world of opal copper lock in the Huahua world, there is a door lock with a price of up to 180,000 yuan, which is the most expensive one in the current high-end locks. The surface of the whole lock adopts 24K pure gold plating, and the surrounding of the lock. Inlaid more than a thousand high-grade diamonds, the production of materials alone is expensive. Some special models of the door locks are also inlaid with crystal or diamonds, so that the door locks have a more magnificent and dazzling effect.

In addition to gold and silver materials, another important reason for the high price of expensive door locks is not only the design is very beautiful, but also the production process is also very particular, so that the door locks can decorate the overall home improvement atmosphere with the attitude of art. The reporter found that the design of high-end door locks is dominated by European classical styles, which looks solemn and dignified.

The lines on the door locks are more eye-catching. The designer engraved the complicated European ancient patterns on the locks, exquisite designs, and fully integrated the essence of European classical sculptures and paintings. This type of lock is most suitable for use in European-style atmosphere. Luxury homes.

1, the classification of locks:

In terms of door locks, door locks, bedroom locks, channel locks, bathroom locks, etc. are used depending on the purpose; ball-shaped locks, handle locks, mortice locks, and locks are used according to the shape. Ball locks and handle locks have three functions: lock, handle, and touch ball. Stay locked to install door handles.

1.1 door locks: play a safe role, it is also known as insurance locks or anti-theft locks.

1.2 channel lock: the role of the handle and the impact of the door, suitable for kitchen, living room, living room, dining room and children's room.

1.3 Bathroom lock: It can be locked inside, and it can be opened with a key outside the door. It is suitable for bathroom or bathroom.

1.4 bedroom lock: locked in the inside, the outside must be opened with a key, suitable for bedroom and balcony doors.

2, the lock material

Lock materials mainly include copper, stainless steel, zinc alloy, steel, aluminum or aluminum alloy.

2.1 Copper: The most widely used, good mechanical properties, corrosion resistance and processing performance are good, bright color, smooth surface, high density, no porosity, trachoma.

2.2 Stainless steel: Durable, brighter and brighter. Good strength, strong corrosion resistance, and constant color.

2.3 Zinc alloy material: poor strength and rust resistance, easy to make complex pattern locks.

2.4 Iron and steel: Better strength, lower غير مجاز مي باشدt, generally coated, easy to rust.

2.5 Aluminum or Aluminum Alloy: Common aluminum alloys are soft, light, and have a lower strength and are easier to shape and shape.

3, the purchase of locks

3.1 To select the copper core, but some of the core is plastic, only covered with a layer of copper at the core.

3.2 All-copper nickel plating and iron-nickel plating are almost the same in appearance, but the price difference is very large. Generally, the copper strips are silent, the iron triads are not muted, the copper triads are fine workmanship, and the iron triads are relatively rough.

3.3 When the ball type is installed, such as eccentric core, etc., it is not easy to install, and it is easy to go wrong.

3.4 The fastest selling now is the handle lock and the ball lock is obsolete.

3.5 The smaller the sound, the better.

3.6 From the key shape, the pit key has a higher security than the dental key, and the pit key must be lost when the key is lost.

3.7 The more square-headed tongues, the better the security.

3.8 Enterprises with high reputation, stable quality and good after-sales service should be selected.

3.9 First, check whether the product packaging is complete (including the implementation of standards, grades, business name, address, date of production), whether the packaging is firm, and whether the instructions are consistent with the product.

3.10 Observe whether the locks, locks, lock tongues, handles, and components and related parts are complete, and whether the surface color of the electroplated parts and painted parts is bright and uniform and there are signs of rust, oxidation, and damage.

3.11 Check whether the product use function is reliable and flexible. Two or more controls should be selected for comparison.

3.12 When buying a two-way lock product, you must use all keys to lock the inner and outer lock switches.

3.13 The product should also be inspected for insurance. It is recommended to try each lock at least three times.

3.14 choose the use of environmental protection equipment, such as dry and wet, the structure of the door, thickness, left open or right open, open or open.

3.15 Select as many keys as possible to lock the teeth, because the more teeth, the greater the difference, the lower the lock open rate.

According to the statistics of the order opening, since 2016, the order opening has increased by 150% year-on-year from the first six months of last year. The back-office data has increased by 120%. The number of new projects has increased by more than 200, and the number of customers has far exceeded the same period. It is worth mentioning that unlike the two-year community-based customers, today's customer groups including campuses, smart parks, and warehousing are also booming. There are indications that the era of mobile phone access has arrived.

The rise of mobile phone access control has two important factors: On the one hand, thanks to the continuous improvement of electronic manufacturing processes, mobile phones have begun to be widely used, and with the continuous expansion of mobile phone application technologies, the mobile terminal services have been expanding, and users have adopted mobile phone terminal application habits. to make. On the other hand, the combination of the Internet and offline services provides users with convenient mobile services. The demand for community apps is expanded. After the mobile phones are opened and embedded, the use of APP users is increased, which can provide high access to venues such as communities and office buildings. Quality safety protection.

With the development of mobile phone access control technology, mobile phone door opening experience is getting better and better. Regardless of security or convenience, mobile phone access control has unparalleled advantages compared to traditional card access control, such as remote authorization, real-time control of permissions, In addition, in the era of information fragmentation, access to data through mobile phone access statistics will be conducive to the scientific and rational management of access to the property or government public sector.

It can be seen that "mobile phone access + real estate" has become an industry trend. In the future, whether mobile phone access control is an increase in sales volume or an extension of application scenarios will be the trend of the times.

High brightness

Obviously, the higher the brightness, the more distant from the light irradiation, a single LED optical output power is generally 5 ~ 15mW, while the brightness can be increased by increasing the current, but the limitations of the material itself *** is, infrared photoelectric conversion efficiency is not high, only 20% of light, the remaining 80% is thermal energy. Therefore, while increasing the brightness, it also generates more heat energy, which is obviously not feasible for the key device CCD of the camera with strict working temperature requirements. In addition, many LED combinations use PCB boards as a carrier, and the heat dissipation performance is not good. The array infrared camera's light source, through the dozens of high-efficiency and high-power wafers through a high-tech package on a flat surface, a well-configured thermal device. At the same time increase its photoelectric conversion efficiency, brightness is about 100 times that of a single LED.

Small

mentioned earlier, the use of a highly integrated array infrared advanced packaging technology, a packaging wafer dozens infrared array chip, only the size of a fingernail. Imagine what the size of a few dozen individual LEDs will be combined with. The small size is the main reason for ease of use. If dozens of individual LED combinations of infrared light sources are installed on a high-speed dome, the effect is conceivable. Known.

long life

The array infrared technology ensures a good working condition of the CCD, and its service life is 9 times that of ordinary LED infrared cameras. The ordinary LED infrared camera places the LED light emitting tube and the camera in a cavity, and the heat of the LED tube cannot be effectively dissipated through the PCB board. The temperature problem seriously restricts the service life of the CCD. After 3 months of using ordinary LED infrared cameras, they begin to show signs of aging. The problems such as blurred pictures, whitening, lack of contrast, etc., have a direct impact on product use results, and even the entire camera is scrapped.

efficient

Determined by the characteristics of the semiconductor itself, its luminous efficiency and heat dissipation performance is a benign-ring. The better the heat dissipation performance, the lower the operating temperature and the lower the operating temperature can better guarantee the luminous efficiency. On the contrary, it is a vicious cycle of falling into a constant decline in efficiency. In addition, our power supply system uses its own patented high-frequency spike power supply to ensure greater efficiency.

Light uniformity

As we all know, each ordinary infrared LED has a sphere in front of it, which is a separate optical design to change the size of the spot. When multiple infrared LEDs are combined around the camera lens, the emitted light is composed of a plurality of light spots overlapping, the overlapping part of the brightness will be particularly high, and at the same time form a circle, that is, "flashlight effect", the night vision screen effect of course It is uneven. The array infrared camera is equivalent to a large point light source. Through special optical design, the light is evenly irradiated to the monitored object, and the brightness of the middle and the surrounding of the obtained monitoring picture is the same.

With the improvement of the national economy and the development of road traffic, intelligent transportation has become a research focus in the field of transportation technology. As the core component of intelligent transportation, license plate recognition plays an important role in the intelligent management of traffic management. At present, the main road vehicle monitoring technology is image or video recognition. This illegal video capture and electronic camera supervision technology has certain defects in its use, that is, it cannot accurately capture every car. Radio frequency identification (RFID) technology is a non-contact automatic identification technology. The use of radio frequency identification technology can make up for the lack of video recognition and provide digital information for vehicles, automation of vehicle identification, and intelligent management of vehicles. A good smart platform.

In this paper, the urban road vehicles as the main research object, through the collection of electronic tags and video license plate number, dual-machine matching recognition. It can automatically monitor the passing vehicles, constrain the driver's illegal behavior, improve the level of traffic management, and reduce the occurrence of traffic accidents.

1, RFID electronic tag identification system

The components of a complete RFID system are: electronic tags, readers, antennas, and application system software.

(1) Electronic tag electronic tag A module and a memory chip are collectively packaged in a single card. By operating each electronic tag, the tag information can be stored and managed at any time. For specific information, Protect it with encryption. This design adopts electronic tags conforming to the ISO18000-6C international standard. Each electronic tag storage area is divided into four parts: RESERVED area, EPC area, TID area, and USER area. The logical addressing of all memory banks starts from 00h. The RESERVED area is used to store the password required for the kill and access functions; the EPC area is used to store the code for identifying the tag attachment object; the TID area is used to store the unique serial number written when the tag is shipped; and the USER area is used to store user-specific data. In this design, the EPC area is used only as an electronic identifier, and the license plate number, electronic ID number, vehicle body color, vehicle type, and a certain coding rule are stored in the USER area.

(2) RFID reader The RFID reader mainly reads and writes data in the electronic tag, and uses the space electromagnetic field to read the tag content and send control commands to the tag. Another important role of the reader is to determine the operating frequency of the entire RFID system. The operating frequency and power of the reader will directly determine the communication distance between the reader and the electronic tag. The general reader includes an antenna, a radio frequency module, a control module, and various types of interface modules connected to the computer.

(3) The antenna antenna is a key part of the wireless radio frequency system. Its main function is to convert the electromagnetic wave emitted by the electronic tag into a current signal and transmit it to the reader. At the same time, the current signal of the reader is converted into an electromagnetic signal and transmitted through the antenna. When the electronic tag enters a valid working area, the RF pulse from the receiving reader is rectified to charge the capacitor. When the capacitor voltage is regulated, it can be used as the working voltage of the tag, so that the electronic tag has enough energy to encode itself. Information is sent via the built-in RF antenna. The reader antenna receives the modulated signal sent from the tag and transmits it to the reader signal processing module through the antenna adjuster. After demodulation and decoding, the reader sends the valid information to the background host system for related processing. The host system recognizes the identity of the tag according to logical operations, performs corresponding processing and control for different settings, and finally issues an instruction signal to control the reader to perform different reading and writing operations.

(4) Application System Application system is mainly composed of middleware and application software. The middleware is composed of host, server, and communication hardware interfaces. It is often used to build computer network resources and enables various application technologies to implement data communication and information sharing. Application software is at the upper level of the hardware platform and is a system software or stand-alone program. The data processing of electronic tags by application programs is implemented through RFID middleware. The middleware is connected to the application port through an application program interface (API) so as to realize the instructions and data of the application program-middleware-reader-electronic tag. Transmission, and then to read and write electronic tags.

2. Video license plate recognition system
Video recognition technology is a technology based on computer vision technology and video image processing, which monitors and analyzes road surface moving objects. It can detect vehicles on monitored roads and automatically extract vehicle license plate information (including Chinese characters, English letters, and Arabic numerals. And number plate color) after processing. The generally complete video license plate recognition system includes a front-end system, a communication system, and a back-end system.

(1) The front-end system is composed of a road traffic video surveillance subsystem, a tunnel traffic video surveillance subsystem and a high-point traffic video surveillance subsystem. The main functions to achieve are: video capture and return, high-definition video charge coupled device (CCD) monitoring camera equipment to obtain video, and sampling the video stream, analyzing the license plate number, using international coding format, Digitize the video back to the back office system.

(2) The communication system adopts wired or wireless transmission, and the data of the front-end system is delivered to the back-end system.

(3) The back-end system is mainly used to parse the data collected by the front-end system and realize video surveillance, playback, system management, and query functions.

3, RFID and video two-machine recognition system construction

3.1 The basic work flow of RFID system This design adopts a reader conforming to the ISO18000-6C international standard. When the target vehicle carrying the electronic tag appears in the working range of the reader, the magnetic field emitted by the reader is all electronic tags in the area. Read and write operations, when each electronic tag receives the signal from the reader, parses according to the received signal, returns a high-frequency carrier signal containing the target information, and transmits it through the analog RF module in the card. The receiving antenna receives the electronic tag. The transmitted carrier signal is parsed by the reader decoder to extract the corresponding information, and ultimately realizes the system's automatic identification and information collection of the target vehicle.

3.2 Dual-system system identification process In this design, the RFID system identification distance can reach 20m ~ 25m, so the entire dual-system identification system will be implemented from the RF system. First, the inventory operation is performed, and the inventory operation is mainly used to detect whether there is an electronic tag in the radio frequency area. In order to avoid undetectable conditions due to the speed of the vehicle, the interval between each check operation is as short as possible, which is about 0.2 seconds. The length of the detection area is generally about 5m ~ 15m, so when the vehicle is less than 180km/h, it can be detected at least once, but usually the inventory operation can detect several times to dozens of times, which is determined by the speed of the vehicle. . After detecting the electronic tag in the area, the number of electronic tags in the radio frequency area and the electronic product code (EPC) of each tag can be obtained. Since the EPC code is used as the unique identifier of the tag, the EPC code is used to locate the corresponding tag. Read the data in the label's USER area and store the resulting contents in a temporary list.

Since the inventory operation is performed once every 0.2s, a large amount of duplicate data will be obtained, excess data needs to be removed, leaving only the record of entering the antenna RF area for the first time. The first data segment of this record is the timestamp in milliseconds, and the second The data segment is the contents of the USER area, and the maintained data is stored in the original ID database.

The video recognition system uses dynamic triggering, and the camera can set the trigger position and lane width. When the vehicle travels to the trigger position, a trigger photograph is taken and one trigger triggers at least 3 photographs, namely a license plate photograph, an illegal photograph, and a panoramic photograph. The license plate photos are subjected to positioning, character segmentation, character recognition, etc., to obtain vehicle number plates and other information, and the license plate information is stored in a video recognition database.

The original ID database is the core part of the whole set of dual-machine recognition system. It matches the video license plate number of each photographed and the electronic tag data in 5s one by one. The main content of the match is the video identification number and the license plate number of the USER area.

Matching results are divided into two types: match success and match failure. If the match succeeds, it means that the video number finds the corresponding electronic tag number, so there is no case of vehicle deck and belongs to the legal vehicle. The license plate information and the electronic tag information identified this time are also stored in the corresponding relation database. Matching failure includes two kinds of situations: one is due to hardware system identification problems, light or angle problems lead to video system or radio frequency system identification error; the second is in the case of video and RF systems are working properly, the match is not successful, indicating the existence of the number Card fraud, decks and other conditions, the car is illegal vehicles. The video identification information and tag information are stored in two separate databases. In both databases, the first segment of the stored data is a millisecond timestamp, which is beneficial to the management of the database and reduces the difficulty of later manual enforcement. At the same time, in order to ensure that the collected video identification number traverses the speed of the entire database, it is necessary to periodically clear the original ID database and clear it approximately once every 1.5 minutes.

4, the experimental results

The RFID part of the dual-system identification system uses the ZXRIS6700 reader, the ZXRID6602 card issuer, and the ZXRID2621 ceramic tag. The maximum communication distance of the reader is 25m. The maximum transmission rate is 160Kb/s in the forward direction and 640Kb/s in the reverse direction. The video recognition part adopts the Haikang iDS-2CD9361-S type camera with 5 million pixels, which can realize dynamic triggering and front-end analysis. Dual-machine identification equipment installation shown in Figure 5.

In the one-way two-lane road, since the installation amount of the electronic tag is relatively small, about 100 sheets, the dual-machine matching recognition function can be well realized, and the obtained data can be stored in the database according to the specified coding rules. . For matching failed data, highlight the database. The system is easy to install, with simple networking and simple operation. It can provide application reference for the promotion of large-scale dual-machine recognition technology.
