　　Chapter 3 System Overview

　　3.1 System principle

　　The APS real-time positioning and tracking system uses RFID (electronic tag) as the most advanced identification code at present. It has the characteristics of not easy to break, reliable data, long service cycle, and long effective communication distance. It is an alternative to barcode and infrared identification. The best choice. Install it on the controlled target as the unique identifier of the target for tracking and positioning.

　　At work, managers use networked wireless identification base stations to track and locate targets.

　　3.1.1 Electronics

　　Simply put, electronic tag (RFID) technology is a non-contact automatic identification technology. Its basic principle is to use radio frequency signals and their spatial coupling and transmission characteristics to realize automatic machine identification of stationary or moving items to be identified.

　　The radio frequency identification system generally consists of two parts, namely the electronic tag and the reader. In the application, the electronic tag is attached to the object, equipment, and person to be identified. The reader is used to automatically remove the electronic tag in a non-contact manner when the object, equipment, or person to be identified It is agreed that identification information is taken out or specific information is written, so as to realize the function of automatically identifying items or automatically collecting item identification information.

　　Since RFID does not require a light path between the tag and the reader, the shortcomings of other automatic identification systems (such as bar codes) are avoided. This ensures that the RFID system can be used in harsh environments, such as dust, dirt, high humidity, and poor visibility environments. The biggest advantage of RFID is that it can still get a satisfactory read and write speed under the above-mentioned harsh environment. In most cases, it can respond within 100 milliseconds. In addition, the reading and writing of RFID is completely automatic and transparent, and there is no need to manually scan the tracked object, nor does it need to activate the magnetic stripe reader, IC card reader, etc. like other contact tag technologies.

　　3.1.2 The working principle of RFID automatic identification

　　The system composed of RFID and short-range communication equipment mainly includes two parts: smart RFID, RFID read-write unit (Read-Write Units, RWU). The wireless communication between the read-write device RWU and RFID realizes the communication between the information management system and RFID. Information exchange.

　　The read-write device RWU is an RFID read-write controller, which is composed of a microprocessor, a security module, a microwave communication controller and communication interfaces such as RS232, 485, TCP/IP, etc. It uses short-range communication protocols and microwave wireless transmission methods to realize RWU For the purpose of safe and reliable information exchange with RFID, RWU connects to the host computer through RS232, 485, WIFI, GPRS, TCP/IP, etc., receives control commands and data from the host computer and returns data.

　　RFID is a mobile device with microwave communication function and information processing and storage functions. RFID built-in a small real-time task system to complete the internal memory, I/O, power supply, communication protocol, key, algorithm, command protocol processing and other functions of the RFID.

　　The core of the wireless communication protocol adopted by the short-range communication technology is the cell segmentation formed by the coverage of low-power microwave antennas, and the time division multiple access and synchronous communication mechanism based on the HDLC protocol are adopted to realize RWU- by designing corresponding processing and control software. Two-way data transmission and information exchange between RFID.

　　3.1.3 Principles of regional positioning

　　A B C is the reader, the receiving range is constant, tag1 tag2 tag3 is the same parameter and gain type tag. The gain can be cycled automatically (0db 1db 2db 3db respectively). When transmitting data, it can also transmit its own antenna gain data.

　　Schematic diagram:

　　Take the icon tag1 as an example,

　　When the maximum tag gain is 2db, the ABC reader can receive the signal

　　When the maximum tag gain is 1db. AB reader can receive the signal

　　When the maximum tag gain is 0db, the A reader can receive the signal

　　From this, it can be calculated through the software that tag1 is closest to A, that is, tag1 is positioned near A to achieve regional positioning

　　Take tag2 as an example:

　　When the maximum tag gain is 2db, the ABC reader can receive the signal

　　When the maximum tag gain is 1db, the ABC reader can receive the signal

　　When the maximum tag gain is 0db, the B reader can receive the signal

　　The software can also calculate that tag2 is closest to B, that is, tag2 is positioned near B.

　　3.2 The overall structure of the system

　　System network structure

　　3.2.2 Schematic diagram of system positioning

　　As shown in the above figure: the reader is fixed at different predetermined positions and has a larger receiving range; when the electronic tag enters the working range of the reader, the reader will receive the signal sent by the electronic tag, according to various After the reported data is analyzed, the system can determine the area where the electronic tag is located, thereby realizing the range positioning of the electronic wristband.

　　In practical applications, each reader of the network version will be assigned a fixed IP address and placed according to the site terrain. When the person or object wearing the electronic tag passes through the working range of the reader (such as the celebrity in the picture), the electronic tag worn by the person or object will send the information to the reader. When the reader receives the information sent by the electronic tag and transmits it through the network, according to the electronic tag ID number, the receiver's IP address, and the data on the equipment placed on the site, it can be concluded that "someone/something is in a certain The record of passing a certain monitoring area at a time, to realize the tracking and monitoring of people or objects.
