摘　　要：介绍了一种基于MLX90621红外传感器的开关柜母线接头温度无线监测系统。采用STM32微控制器、MLX90621红外传感器和nRF24L01无线通讯模块,设计了这种温度无线采集系统的硬件和软件部分。通过非接触式MLX90621红外传感器阵列可实时采集高压开关柜的母线接头温度。其数据可通过nRF24L01通讯模块和串口上传给上位机进行显示。由于具有成本低、稳定性高、抗干扰强等优点,该系统适用于开关柜内部的复杂磁场环境。A wireless switch cabinet bus connector temperature monitoring system based on MLX90621 infrared sensor was presented. The hardware and software of the wireless temperature acquisition system were designed by using a STM32 microcontroller, a MLX90621 infrared sensor and a nRF24L01 wire- less communication module. The temperature data of high voltage switch cabinet bus connectors were measured by the non-contact MLX90621 infrared sensor array in real time and were uploaded by the nRF24L01 wireless communication module and the UART interface to the host computer for displaying. Because of the advantages of low cost, high stability and anti-interference, the system was suitable for the complex magnetic field environment in switch cabinets.
