With the features of wide distribution, adverse environment and large numbers of agricultural machinery in our country, it could cause a lot of manpower and material consumption to use technologists to follow-up and detect agricultural machinery for long-term, and it is low level of automation. Also there are some problems such like high cost, poor accuracy in acquisition and energy-wasting in the traditional online monitoring methods. Thus, a remote monitoring system for a group of agricultural machinery was established. Remote data acquisition integrated with GSM and GPS technology and engineering signal receiver were consisted in the hardware device; and the features such like automatic monitoring of operating status, harvesting areas and geographic information, and data uploads actively were implemented. Flexible remote data monitoring centre based on LabWindows/CVI was developed using a shared set of parameters architecture, and specific measurement and control software aiming at different kinds of agricultural machinery group and different tasks could be efficiently developed by users. The goals of real-time displaying of uploaded data, saving data, accurate positioning of geography information and following of running track were realized by monitoring center. Combined with a Microsoft Access database management system, dynamic combination and centralized group management of agricultural machinery were realized. Through a field test, it shows that the requirements of on-site real-time data transmission and accuracy data collection of agricultural machinery are implemented by the system. By the shared set of parameters of architecture, the efficiency of software development for object-oriented measurement and control system is greatly improved.
