Abstract: To solve the problems in agricultural machinery working field, such as information lag, lack of effective means of scheduling agricultural machinery, and low efficiency, an agricultural machinery monitoring and scheduling system integrated with Geographic Information System(GIS), General Packet Radio Service(GPRS) and Global Positioning System(GPS) technologies is presented. To realize data collection immediately and real-time monitoring and scheduling agricultural machinery remotely, GPRS data transmission technology and MapObjects are adopted in the system. To overcome traditional pathfinding algorithm’s shortcomings in real-time computation, A-Star algorithm is applied to plan the route of agricultural machinery. Application results show this system can schedule agricultural machinery effectively and improve the efficiency.
