摘要/Abstract

摘要： 工业机械装备的在线实时状态监测和故障预警是保障工业生产安全、提高工业生产效率的重要手段。目前大多数机械装备的状态监测设备都存在体积大、功耗高的问题，并且依赖于电缆或化学电池供电，机动性、灵活性、环境适应性差。本文提出了一种基于复合振动能量采集器的高集成度自供电无线传感监测微系统，设计了压电-电磁-摩擦电三种发电方式复合的能量采集模块采集机械设备的振动能量，通过能源管理电路进行电能存储和整个系统供电。搭建了基于振动-温度高集成微纳传感芯片的环境信号采集及无线传输电路，并进行了低功耗电路设计。系统集成能源管理模块和传感电路模块后进行了采煤机状态监测测试。测试结果表明，该系统能够实时采集煤机装备的振动、温度信号并无线传输给上位机，同时也证明系统内的能量采集模块能够收集采煤机的振动能量并转换为电能带动传感电路模块工作，这将为工业物联网传感网络节点的自供电、无线化发展提供技术支持。

Abstract: The on-line real-time monitoring and fault warning of industrial machinery and equipment are critical in ensuring the safety and improving the efficiency of industrial production. At present, most of the mechanical equipment condition monitoring devices are bulky, high-power consumption and rely on cable or chemical battery power supply. In this paper, a high integrated self-powered wireless sensor micro-system based on the hybrid vibration energy harvester is proposed. The energy harvesting model with hybrid piezoelectric-electromagnetic-triboelectric power generator and energy management circuit is designed to harvest and convert the vibration energy of the mechanical equipment into electric energy for power storage and supply of the whole system. The high-integrated vibration-temperature micro-sensor chip with lower-power signal acquisition and wireless transmission circuits is established. After integration of the energy harvesting model and the micro-sensor with circuits, the experiment of the whole system on the coal cutter is carried out. The results show that the vibration and temperature signals of the coal cutter can be monitored and transmitted wirelessly to the host computer in real time. It also proves that the energy harvesting model in the system can harvest vibration of the coal cutter and convert it into electrical power to drive the system. This research will provide a technical support for the self-powered and wireless development of sensor network nodes in the industrial internet of things.

Key words: vibration energy harvesting, self-powered, sensor monitoring, wireless transmitting, energy management
