A manhole covers intelligent monitoring terminal based on dual frequency RFID and acceleration sensor

Abstract. For management the manhole cover effectively, the manhole covers intelligent monitoring

terminal (MCIMT) based on dual frequency RFID and acceleration sensor was proposed in this paper.

Through hardware designing, alarm algorithm designing, program debugging and packaging, we

developed the MCIMT. The key performance testing and demonstration system operation shown the

following results. Firstly, the MCIMT communication distance can achieve 800 meters under the

open conditions and 300 meters under the occluded environment reliably. Secondly, the MCIMT

embedded special state estimate algorithm can output the correct scene sate of manhole cover. Thirdly,

the MCIMT could operation 3 years in manhole cover. Lastly, the demonstration system based on the

MCIMT can alarm accurately and timely
