The Research of the ZigBee and RFID Fusion Technology in the Coal Mine Safety

RFID is a non-contact automatic identification technology that uses radio frequency signals automatic recognizes target and access to relevant data. The identification work does not require human interference and can work in variety of harsh environments. But if there is no network to transmit data, it will be difficult to play its advantage. Under the influence of environmental conditions, the traditional wired network may not be a better way to achieve. The feature of wireless sensor network is no center and self-organize, it is a powerful complement of RFID, and can solve the drawback of poor anti- interference, the effective transmission distance short. Based on the ZigBee technology and the RFID technology of information-fusion technology: the former used to monitor the target environment conditions, the latter used to identify target objects. Complementary and interdependent of the technology can effectively solve the problem of RFID data transmit in the mine and can also better perceive the safety hazard exists in coal mine.
