Abstract The monitoring configuration software is a platform supervisory control and dataoriented tool，which can quickly and easily construct and generate PC monitoring system, significantly reducing industrial monitoring and controlling software development cycle, as well as improving the development efficiency. This design is a simple temperature and humidity control system, which is a kind of greenhouse environment based on configuration software MCGS remote monitoring and management system. Applying S7200 to control algorithm of greenhouse environment parameters setting, automatic control was achieved by executive components such as air conditioner, heater, which conform to the requirements of the people needed to make the greenhouse environment temperature and humidity, to improve the production and quality of greenhouse.
Greenhouse system uses Ltd. Beijing Kunlunstate design and development of software for the configuration PC configuration of the system design， completing the system of monitoring, alarm, tabulation, remote control, which have reliable and stable performance, low cost and high accuracy characteristics, not only improving the quality of greenhouse, and reducing the cost increase effect and having good popularization and application value. The software is simple, intuitive image motion. the components selection of greenhouse system, PC software configuration and the design of the control program is mainly introduced in this paper.
