摘　　要：介绍了一种带电源切换功能的多通道无线模拟量输入输出模块。该模块集模拟量的采集和输出为一体,可同时采集多路传感器传来的监测信息,经过A/D变换后利用无线收发模块上传至PC端,并设计了一种电源电路,具有电压切换功能,可为模块以及供电电压等级不同的多路传感器供电,解决了需要另外布线的问题。这种模拟量输入输出模块具有高精度、多通道、高实时性、无线传输、电源切换等功能,可满足工程实际中需要利用多个传感器监测多个量的需要。This paper introduces a multi channel wireless analog input and output module with power supply switching function. It sets the analog input and output as a whole,can be collected simultaneously from multiple sensor to monitoring information,after A/D conversion using wireless transceiver module and uploaded to the PC terminal. And designed the power supply circuit with voltage switching function,which can power supply the module and different supply voltage levels of multi-channel sensor power to solve the need for additional wiring problems. The analog input and output module has the functions of high precision,multi channel,high real-time,wireless transmission and power supply,which can satisfy the need of multi sensors in engineering practice.
