Research About The Wireless Control System Of Greenhouse

As the state take more attention to agricultural development, agricultural facilities construction also tends to improve gradually. Facilities for agricultural sustainable development of agriculture as an important way, has a growing number of research institutions and relevant sectors of concern. Greenhouse Construction is the advanced stage of agricultural development facilities, and establishing current stage of development of the greenhouse project, improving the level of the greenhouse control technology has important significance.Environmental measurement and control technology based on the level of the greenhouse behind low-tech situation, the subject presents a more intelligent, reliable measurement and control technology solutions to the greenhouse. The overall system is divided into three parts, by the PC control software, base stations and a number of common components from the station. From the station through the base station and multiple wireless data communication technology to form a branch structure of master-slave, slave master chip high cost of MSC-51 microcontroller, is mainly responsible for greenhouse parameters of the collection, processing and control. The base station is responsible for sending data from the station to upload and receive control commands sent by the host computer forwards from the station. Base station with the host computer PC through RS-232 serial communication, PC software and Access database using VB6.0 design a friendly interactive interface.Overall system design is reasonable, to provide users with intuitive operation and reliable monitoring of greenhouse parameters, and can operate by remote control greenhouse environmental parameters change. Higher cost of the system, reliable, and easy to upgrade expansion, the current economic level of China's agricultural development facilities under a high reference value.
