摘　　要：为解决农业大棚种植环境监测的近距离、高成本、低精度问题,设计并实现一种太阳能供电的农业大棚环境监测系统.以STM32F103C8T6单片机作为主控芯片,传感器采集大棚的CO2、温度、湿度参数,采用射频技术和通用分组无线服务(general packet radio service,简称GPRS)完成设备间的数据传输.通过继电器控制卷帘的升降、补光灯的亮灭和喷灌设备的启停.通过Web客户端能实现存储和显示数据.实验结果表明该系统达到了设计要求.该系统能实现远距离、低成本、高精度的监测,具有低功耗、可扩展的优点.In order to solve the problems of close distance,high cost and low precision of environmental monitoring of agricultural greenhouses planting,a solar-powered environmental monitoring system for agricultural greenhouses was designed and implemented.STM32F103C8T6 single chip microcomputer was used as the main control chip.The sensor collected the greenhouse’s CO2 and its temperature and humidity parameters,then the data transmission between the devices was completed by the radio frequency technology and general packet radio service(GPRS).The rise and fall of the curtain,the lighting and extinguishing of the supplementary light and the start and stop of the sprinkler equipment could be controlled by the relay.The storage and display of data could be implemented by the Web client.The experimental results showed that the system could meet the design requirements,and the system could realize long-distance,low-cost and high-precision monitoring and had the advantages of low power consumption and expansibility.
