  Principle of industrial RFID identification system

  

  A complete RFID system consists of reader, RFID tag and computer system.

  

  Reader is a key part of RFID system, which is mainly composed of wireless transceiver module, antenna, control module and interface circuit. These readers can write and read the information in RFID tags, and they are an important part of the data acquisition terminal in RFID system. The reader communicates with the RFID tag through the wireless transceiver module, the control module is responsible for processing instructions and data, and the interface circuit is used to connect the reader and the computer system.

  

  RFID tag is a data carrier used to mark the object to be traced, which records data information and can read and write with RFID reader. Tag antenna and tag chip are the core components of RFID tag. The tag antenna is used to receive the signal sent by the reader and transmit it to the tag chip, which is used to store and process data information. By interacting with the reader, the RFID tag can automatically identify objects and transmit data information.

  

  The computer system includes PC or PLC and other controllers, and even WMS, MES, ERP and other systems at the user’s site, which are used to receive the information fed back by RFID readers. This information can include data of the object to be traced, identification results, statistical data, etc.

  

  In a typical RFID system, the computer system, reader and RFID tag cooperate with each other to complete the tasks of automatic identification, data acquisition and transmission. By using RFID technology, the accuracy and efficiency of data acquisition can be improved, the cost can be reduced and the work efficiency can be improved.

  Application advantages of industrial RFID identification system

  

  In the industrial production environment, data recognition technology plays a vital role. At present, barcode, QR code and RFID technology are commonly used data identification technologies in industrial scenes. However, each technology has its specific limitations. For example, although bar code technology is widely used, it needs to match a specific light source when reading data, and it has high requirements on the brightness of the light source. In addition, it needs to be scanned by the scanner aiming at the light in the visible range in order to read the information successfully. This technology requires high mechanical accuracy. Once the objects bearing bar codes such as trays are deformed, the bar codes may not be recognized. In addition, barcode recognition can only be scanned one by one, and only one barcode can be read at a time, which greatly reduces the work efficiency. Moreover, because the bar code is easy to wear and dirty, its service life is short, and it cannot be reused after being modified.

  

  On the other hand, although the two-dimensional bar code provides a solution in terms of information capacity and adds the function of information error correction, it can realize the functions of reading and anti-counterfeiting on the surface of articles through laser engraving technology, but there are still some disadvantages. For example, its application scenarios are relatively limited, which can not fully meet the needs of complex application scenarios in industrial production.

  

  To sum up, although barcode, QR code and RFID technology have played an important role in industrial data identification, they all have certain limitations. Therefore, it has become an urgent problem to find a more efficient, reliable and adaptable new data identification technology in the industrial field.

¡¡¡¡

¡¡¡¡Code words

¡¡¡¡

¡¡¡¡The UK began using umbrellas only in the 18th century. The Bernas umbrella was once a special item for women, which expressed women¡¯s attitude towards love. Holding the umbrella upright means being faithful to love; holding the open umbrella in the left hand means holding the umbrella tightly. Slowly shaking the umbrella means lack of confidence or distrust; leaning the umbrella on the right shoulder means not wanting to see you again.

¡¡¡¡

¡¡¡¡Social significance

¡¡¡¡

¡¡¡¡In ancient China, umbrellas symbolized power for emperors, generals, and dignitaries, as clearly recorded in the ¡°Book of Jin¡± and ¡°Yufuzhi¡± in Zuo Zhuan. The records show a strict hierarchy associated with their use. The materials, colors, and sizes of umbrellas are like the black gauze on the head and the court dress on the body, which also distinguish the official positions. For example, in the Han Dynasty, it was stipulated that the nine ministers and three officials who ate more than 2,000 stones of millet used black. The officials who were not allowed to wear black clothes were all allowed to wear blue. Therefore, in ancient times, the sedan chairs or cars that the emperors or high officials rode on when they went on tours all had umbrella covers to show that they ¡°shaded the people.¡± Therefore, this kind of umbrella is also called ¡°cool umbrella¡±, ¡°Luo umbrella¡±, ¡°all people¡¯s umbrella¡±, and ¡°Huagai¡± in written language.

Brief Introduction of PIR Sensor

  After that, passive infrared sensor Not afraid of the future, dare to fight and fight, and won applause again and again in the market. https://www.sunlit-tech.com

  PIR sensor (Passive Infrared Sensor) is a passive infrared sensor. It is widely used in consumer products such as doorbells, cat eyes, induction switches, night lights, and security because of its low power consumption, low price, and simple use.

  

  

  (1) PIR detection principle

  

  PIR also has another alias, which is pyroelectric infrared sensor. Its detection principle is the pyroelectric effect, that is, the phenomenon that a substance will generate electric charge when the temperature changes. The normal human body temperature is 36-37 degrees, and the infrared radiation released is about 9-10um. The detection wavelength range of pir motion detector is generally in the range of 5-14um. That is, within the detection range of PIR, if there is an energy change of 5-14um wavelength, the PIR sensor will generate a current change, thereby giving a trigger signal. It should be noted here that PIR detects energy changes, not infrared radiation of a fixed wavelength. If an object with a fixed wavelength is not moving, PIR will not detect it.

  

  (2) Advantages of PIR

  

  Low power consumption, typical power consumption is about 10uA

  

  Low price, ranging from one or two yuan to five or six yuan

  

  Easy to use, the simplest one only needs to detect a pin level signal

  

  (3) PIR classification

  

  There are many types of PIR motion detector, which can be roughly divided into the following ways:

  

  Enablement controllable: switchable PIR

  

  Output signal type: digital PIR and analog PIR

  

  Is the sensitivity adjustable: adjustable PIR and non-adjustable PIR

  

  Sensitivity adjustment method: hardware adjustment and software programming adjustment PIR

  

  

  (4) PIR selection

  

  When selecting a PIR sensor, we generally need to consider the following basic requirements: voltage range, operating current, number of pins required, data output format, whether the sensitivity is adjustable, structural package size, and compatibility with the Fresnel lens. Another important consideration is cost. Without considering cost, it doesn¨t matter whether you choose a model or not. Just choose the best one. In actual product development, especially for consumer products, prices are very sensitive. Basically, all bosses want to use the cheapest device and debug it to achieve the best effect, especially for products with large shipments. If you don¨t have high requirements for product quality, it doesn¨t matter. If you have strict requirements for product quality and performance, you need to be very careful when selecting a model to avoid replacing the device when you find that it does not meet the requirements in the later stages of the project.
