Background technology

Internet of Things is through information sensing equipment; Agreement by agreement realizes person to person, people and thing, thing and thing interconnected network comprehensively; Its principal character is to obtain the various information of physical world through modes such as RF identification (RFID), sensors, and the transmission of carrying out information in conjunction with networks such as internet, mobile radio communications adopts the intelligence computation technology that information is carried out analyzing and processing with mutual; Thereby improve intramundane perception, realize intelligentized decision-making and control.

Internet of Things experimental system based on RFID will be sensing layer with RFID not only, and will expand the application of back-end network layer and application layer, realizes the storage of information and the issue of wide area through management system.But the present general structure of Internet of Things experimental system based on RFID is too simple, only is the simple application through the RFID reading tag, can not satisfy the actual demand of Internet of Things teaching field, has limited the development of Internet of Things.

The utility model content

The purpose of the utility model provides that a kind of degree of intelligence is high, dirigibility is strong, favorable expandability, and is easy to operate, use the Internet of Things experimental system of intuitive and efficient based on RFID.

For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of Internet of Things experimental system based on RFID; It comprises RFID central control unit, RFID read-write controller and RFID reading unit, and RFID central control unit, RFID read-write controller, RFID reading unit link to each other successively.

Further improvement as technique scheme:

Said RFID reading unit comprises low frequency read-write cell, high frequency read-write cell and ultrahigh frequency read-write cell, and said low frequency read-write cell, high frequency read-write cell and ultrahigh frequency read-write cell link to each other with the RFID read-write controller respectively.

It also comprises the LCD module, and said LCD module links to each other with the RFID read-write controller.

The RFID central control unit links to each other with the RFID read-write controller through communications interface unit, and said communications interface unit comprises at least a in RS232 communication module, WiFi module, the RJ45 ethernet module.

The utlity model has following advantage:

1, the utility model comprises RFID central control unit, RFID read-write controller and RFID reading unit; RFID central control unit, RFID read-write controller, RFID reading unit link to each other successively; Typical RFID application software system with feature richness; Can accomplish multiple RFID application system, have degree of intelligence height, strong, the favorable expandability of dirigibility, easy to operate, use intuitive and efficient advantage.

2, the utility model can carry out experiments such as RFID embedded programming, signaling experiment, RFID read-write experiment, RFID applicating software programming, and this experimental system has system architecture clearly as the RFID of Internet-of-things teaching experiment system.The utlity model has very strong dirigibility and extendability, make manipulate convenient directly perceived efficient.
