The Remote Wireless Data Acquisition System Design And Development Of Greenhouse Environment

As the economy and the rapid development of science and technology, the rising living standard of the people, the contradictions between resource shortage, environment worsening and population explosion are more and more obvious. So, developing facility agriculture, improving our country agricultural product quality and production efficiency is urgent, and the good performance of environmental data acquisition system provides a good technical support for the development of facility agriculture.The thesis according to the Bixi newly area modern facility agriculture science and technology demonstration base project construction needs and combined with mobile communication technology, ZigBee short distance wireless technology and internet network technology designed a remote data acquisition system of greenhouse environment which based on GPRS and ZigBee technology.The system can copy greenhouse environment related data timely, efficiently and accurately.The thesis mainly elaborated the following three aspects. Firstly, the paper introduced the history and present situation of the greenhouse environment data acquisition system at home and abroad, and then introduced the technology foundation of greenhouse environment data acquisition system, from the project reality requirement put forward the overall scheme of the whole system design and introduced the role of each part in the whole system in great detail. Secondly, the paper devised the system of GPRS digital terminal and data acquisition module, and devised the communication protocol between digital terminal and remote data management center, data acquisition module and digital terminal, and wrote bottom program of digital terminal and data acquisition module. Lastly, the paper debugged each finished software and hardware in the laboratory environment, and proceeded system alignment in the case of the hardware and software meet the requirements. The experimental results showed that:the whole system can real-time, accurate and quick copy greenhouse environment related data with the coordination of software and hardware, can basic satisfy the initial design goal.
