摘要
针对中国北方地区日光温室生产发展需要 ,研制开发了以工控计算机为核心的日光温室环境监控系统。系统采用RS-485远距离通讯与多点数据采集技术 ,各控制单元独立完成数据采集与转换任务 ,通过RS -232/485转换模块与主控计算机进行通讯。该系统扩展性强 ,可同时监控60栋日光温室。
The system was developed directed against the need of greenhouse production in north area of China, in which industry computer was designed as the core RS-485 remote communication and multi-point data collect technology was used so that every unit can finish it's task of data collecting and transforming by itself. The communication between every controlling unit and computer was connected by RS-232/485 transforming module. This system can be extended easily. Sixty greenhouses could be monitored and controlled at same time.
