Study on Underground Pipe Network of Radio Frequency Identification System

The underground pipe network identification system based on RFID technology is introduced. The research involves the embedded technology, radio frequency identification technology and communication technology. The system is composed of intelligent passive electronic tags and detector. Electronic tags are able to receive the transmitted signal of the detector, and then transmit their own information. Detector uses low power embedded system, with Chinese interface, communicate with computer. The information is written to the buried depth of 0.3 meters, and is read to 1.3 meters.Three meters in diameter of the circular area can be detected.
