基于GPRS的温室大棚信息采集及控制 Greenhouses Information Collection and Control Based on GPRS

Abstract

由STC89C52单片机采集信息和智能控制，利用GPRS无线传输模块定时把温室大棚采集到的温度、湿度、光照强度以及CO2浓度等数据传输给上位机(PC机)，实时观察，同时又通过PC机对下位机(单片机)采集的信息进行分析，并发出相应指令给下位机作出相应的控制，如通风设备、喷淋装置、遮阳网等装置。 Greenhouses state parameters (such as temperature, humidity, light intensity and CO2 concentra-tion) which are collected and intelligently controlled by MCU (STC89C52) are transmitted to the host computer (PC) for real-time observation. By analyzing information provided by lower computer (MCU), PC orders STC89C52 to send control commands to ventilation equipment, spray device and Shade net.
