摘　　要：文中设计了一套能实时控制温室内温度、湿度、以及CO2浓度等多参数的温室环境监测系统。该系统以PC机为上位机,低功耗单片机P89LPC932为下位机,由一台PC机与多台下位机组成主从式分布结构,采用总线式RS-485通信网络进行数据传输,可实时传输各环境参数值从而实现远程控制。This paper introduced a greenhouse monitoring system to control parameters of temperature,humidity,CO2 density and so on.The main idea is to design computer distributed auto-control greenhouse system.This system is made up of one PC and several P89LPC932,and the data are transmitted by RS-485 bus communication network.The parameters of greenhouse can be transmitted to the PC real-time in a long distance.
