一种远程无线环境监测模拟装置设计

针对无人值守远程环境监测问题,设计了一个实验模拟系统。系统采用模块化设计,主要由能量收集模块、监控中心模块、传感器监测节点模块、无线传输模块和液晶显示模块等组成。监控中心和监测节点采用AVRAtmega16L单片机作为控制核心,监测节点的环境监测信号编码后通过幅度调制由无线收发模块发送至监控中心。环境监测节点由能量收集模块供电,无需更换电池。该系统功耗低,节点配置灵活,结构简单,可以实现温度、湿度和光照强度的监测、无线传输以及数字化显示。

Design of long-distance wireless environment monitoring simulation equipment

In order to solve the problem of long-distance unmanned environment monitoring,an experimental simulation system was designed,which was composed of energy harvesting module,monitoring center module,sensors monitoring nodes module,wireless transmission module and LCD display module.AVR Atmega16L was taken as MCU of environment monitor center and nodes.Environment information was encoded according to message format firstly.And then,it was modulated by amplitude modulation.Finally the modulated signal was tran...
