System and method for monitoring wireless sensor of coal cutter based on vibration energy harvesting

Abstract

The invention provides a system and a method for monitoring a wireless sensor of a coal cutter based on vibration energy harvesting. The method comprises the following steps that measuring points are set at preset positions of a rocker arm, a roller and a traveling box of the coal cutter, and mounting an energy self-harvesting sensor unit on each measuring point to be used for monitoring related data of the coal cutter; electric energy of a vibrating sensor in each sensor unit is supplied by means of vibrating energy generated in the process of operating the coal cutter; the energy self-harvesting sensor unit transmits the monitored working condition data of the coal cutter to a wireless communication aggregation node in a wireless mode, and the wireless communication aggregation node performs secondary wireless transmission on the received data; and a coal cutter master control system communication module and an underground communication system receive the data subjected to secondary transmission of the wireless aggregation node, and the working conditions of the coal cutter are effectively judged. According to the system and the method, fault diagnosis and prediction mechanism research of the coal cutter can be guided, the problems of power supply and signal wiring difficulty and information island in the process of monitoring working conditions of an electric traction coal cutter are effectively solved, and wireless coal cutter monitoring based on a wireless sensor network is realized.
