Abstract: In order to construct the sensor mine internet of things, this article proposed a mine-used wireless communication system based on TD-SCDMA and RFID. It was pointed out that the smart terminal devices with RFID TD-SCDMA would participate in the construction of perception layer, perceive personnel and equipment state and take the TD-SCDMA system as a unified platform for network transmission. The article analyzed the key technology in the subject, and preferred a technical program which can call, positioning, scheduling, data transmission and platform access, etc.
