The Research Of The Greenhouse Remote Monitor System On The Basis Of The GPRS

In recent years, with the development and wide application of computer technology, sense technology and wireless communications, modern greenhouse techniques are moving in the automatic and informational direction. Shouguang, the agricultural country, leads the china in scale and quantity of greenhouse and has paced the whole nation in the agricultural facilities. Therefore it has great significance to develop the greenhouse remote monitors system, to control greenhouse as a group, to achieve the automation of environmental detection system in production process, and to raise the quality and production of crops. And GPRS solves this question.In greenhouse production management, the environment is playing an important role in the growth, cultivation technique and pest control of crops. Taking flower-culture greenhouse for an example from the actual conditions of flower-production, studying the fusion method of Information Network and Control Network, combining the greenhouse field control network and internet, and realizing greenhouse field control network and internet telecommunication by GPRS. And the paper put a practicable plan to reach the automatic checkout of greenhouse environmental parameter.According to the actual need, the paper finish a remote monitor system based on GPRS. This system run on web server, it can gather field parameter of temperature, humidity by the sensor and can transmit the information to remote computer with wireless GPRS.The technique has advantages of unique design, high automaticity and widely used。It provides reliable support information for distant administrators and offers facilities for agricultural research and production。The research contents and key technologies:The principle of GPRS is explored in depth:to introduce the data acquisition and terminal unit of wireless GPRS and workflows and to design a practicable wireless communication in this paper。Studied the computer network and internet information network to control structure and characteristics. Summarizing the B/S and C/S and combining the GPRS and Data Communication based on TCP/IP. This paper Designs a network plan to realize the communication of the greenhouse field facility and remote server.Analyzing the characteristic and need of greenhouse floriculture environmental monitoring system, designing the structure of remote monitor system, dividing the function module, analyzing of the total system, designing database of Monitoring System by SQLSevrer,adopting VB and PHP.This paper designs remote monitoring software and Web Data Referral System.For the actual needs and solutions, this paper apply strategy to real implementation of the system, introducing performance parameter of software and hardware Accounting for problems and solutions in system debugging.
