Abstract: The low-power wireless transmission of high frequency signal has always been a difficult problem in coal face. According to the specific environment of working face and the characteristics of multi-class wireless bus communication, a kind of wireless vibration sensor based on Bluetooth and a diagnosis and a kind of analysis device based on Bluetooth and Lora with Android and embedded dual-core are developed in the research. The research has realized the vibration diagnosis analysis of different kinds of rotor equipment in the working face and ensured the long-term stable operation of key equipment in the working face, which can reduce the labor intensity of the staff.
