Embodiment Construction

[0025] figure 1 It is a schematic block diagram of the RFID system. RFID is a non-contact automatic identification technology. Its basic principle is to use the transmission characteristics of radio frequency signals and space coupling (electromagnetic coupling or electromagnetic propagation) to realize automatic identification of identified objects. The composition of the RFID system will vary due to different applications, but it is basically composed of three parts: electronic tags, readers and computer database management systems: the information to be sent by the reader is encoded and loaded on a certain frequency The carrier signal is sent out through the antenna, and after the electronic tag entering the range of the reader antenna receives the pulse signal, the relevant circuit in the card chip modulates, decodes, and decrypts the signal, and then processes the command request, password, authority, etc. judge. If it is a read command, the control logic circuit reads t...

Abstract

The present invention discloses a wireless radio frequency identification reader-writer of a campus verification system. The wireless radio frequency identification reader-writer is composed of a single-chip microcomputer, an external data memory module, a keyboard module, a Chinese liquid crystal display module, a radio frequency module, a real-time clock module, a power supply management module, a serial port communication module and the like. The wireless radio frequency identification reader-writer provided by the present invention applies an automatic identification technology, a miniature computer software/hardware technology, a radio frequency technology and an information safety technology and can realize a function of acquiring various campus information. A reader-writer system has the advantages of being portable and intelligent, being small in size and low in cost and power consumption, etc.

Description

technical field [0001] The invention belongs to radio frequency identification technology, in particular to a radio frequency identification reader-writer of a campus verification system. Background technique [0002] RFID (Radio Frequency Identification) is a non-contact automatic identification technology that can realize automatic identification and remote real-time monitoring and management. The communication distance can be from a few centimeters to tens of meters. Its main advantage is that it has strong environmental adaptability, can complete automatic identification, tracking and management without contact around the clock, and can penetrate non-metal for identification, and has strong anti-interference ability. Therefore, RFID technology has been widely used all over the world. However, our country has just started in this area, and most of the equipment still adopts imported technology and achievements. Therefore, it has become the need of today's national econom...
