摘要
针对当下煤机设备状态监测系统时效性差、通信电缆铺设困难、需要定期更换电池等问题,提出了一种基于无线传感器网络与自供电技术的监测系统设计方法。系统由能量采集模块、无线传感器网络及监测上位机组成,通过能量采集模块收集煤机设备振动能量为节点电路供电,采用无线传感器网络与上位机实现设备关键状态信息的采集、传输与处理。测试结果表明,系统可在30 m有效范围内实现对煤机设备运行状态的实时监测,能量采集模块最大输出功率可达378 mW,能够有效收集设备振动能量实现系统能源自供给。
The Wireless sensor network and self-powered technology-based monitoring system was proposed to solve the several problems, such as the poor timeliness of coal machinery equipment condition monitoring system, the difficulty in laying communication cables, and the demand to replace batteries regularly. The system consists of energy harvesting unit, wireless sensor network unit and monitoring software unit;the energy harvesting unit can harvest the mechanical energy of vibration to supply power for the node circuit;the wireless sensor network unit and monitoring software unit realize the collection, transmission and processing of critical state information of equipment. The system can realize the real-time monitoring of machine equipment operating status within 30 m effective range and the maximum output power of energy harvesting unit can reach up to 378 mW, which can effectively collect equipment vibration energy and realize system energy self-supply.
