智能温室测控系统软件的设计与研究

The Design Search on Measurement and Control System Software of Intelligent Greenhouse

针对我国温室科技含量低、现代化智能温室大部分依靠进口的局面,采用先进的计算机技术、微电子控制技术和传感器技术设计出的基于RS-485总线的温室计算机分布式自动控制系统。该系统采用半双工RS-485总线型通信网络和累加与校验通信算法进行数据传输,可以在采集温室环境参数的同时对温室内的温度、湿度、光照和CO2浓度等调节装置进行控制。利用VB6.0面向对象编程技术和Access数据库软件开发出友好的人机界面,通过实时读取历史存储温室内环境参数值,实现了对温度、湿度、光照和CO2浓度等参数的管理和查阅。

Aiming at the situation that the greenhouse of our country is low technological content and nearly all modernization intelligent greenhouses are rely on import, this topic adopts advanced computer technology, micro - electronic control technology and sensing technology to design the distributed automatic control system of the greenhouse computer based on RS- 485 bus. This system, adopts half duplex RS- 485 bus communication network and accumulate and check- up al-gorithm, carry on data transmission. It can collection environmental parameters and control the adjusting devices of the greenhouse. Utilizing VB6.0 face targets database programming technology and Access database software, friendly man -machine interface is developed. By reading and storing the environment parameter value of the greenhouse in real time, the management to four greenhouse environmental parameters, such as temperature, humidity, illumination and CO2 density is realized, which can be consulted conveniently.
