基于GPRS技术日光温室综合环境集散控制系统的研究与设计

针对目前日光温室综合环境调控模型和日光温室群集散控制存在的问题,在研究日光温室微生态环境变化机理的基础上,采用以温度为主参量的日光温室综合环境调控模式,运用单片机控制技术和GPRS技术实现了日光温室群环境因子的采集、无线数传以及控制信号的无线传输和日光温室群综合环境的集散控制,并利用数据库技术和JA-VA技术,通过Web服务器上的接口和Internet上的客户端建立连接,实现了授权用户温室综合环境数据库的远程访问和对温室环境的应急控制等功能,解决了日光温室环境多因素的检测和远程集散监控难题。

A Research and Design on Distributed Control System for Solar Greenhouses Synthetic Environment Based on GPRS Technology

In view of existing situation is the model and control system of synthetic environment in solar greenhouses,it is this research that achieves the distributed control with the data acquisition and remote transfer,along with the wireless transfer of controlling signal,by using the GPRS technology and MCU controlling technology.Take into consideration of the temperature as the key parameter in the control model,based on the research of the varying mechanisms in the micro-ecological environment of it.For overcoming the difficulties on the more factors in the greenhouses environment to be detected,monitored and distributed controlled remotely,the technologies of database and JAVA are made use of in connection with the interfaces of servers in the Web and Client.Thus,the function of remote access the DBS of greenhouses and emergent control environment could be realized by using the system for authorized user.
