英文摘要	In China, cross-regional harvesting operation was generated during agricultural mechanization. It improves the efficiency of crop harvesting and the usage of machineries, and increases the income of the farmers. While the cross-regional operation suffers from several key problems that cannot be resolved by traditional navigator: a) location monitoring for center dispatching, b) path guiding for emergency repairing, c) information exchange between the center and the terminal, d) digital map suitable for urban usage is not detailed enough for agricultural areas. In order to solve the problems, a new dynamic navigation technology is used to develop the cross-regional harvester monitoring and dispatching system. The C/S system, which consists of visual GPS terminal, wireless network, server, and monitoring terminal, is established by the authors. Based on the real-time position of the harvesters, the system could provide them location-based dynamic information. The monitoring terminal could send the navigation information including the destination and path to GPS terminal via defined protocol. When the GPS terminal receives the information, it displays the task message and draws the destination and path on the map. Then the driver could reach the destination just following the specified path. It is convenient to allocate and dispatch the harvesters, especially for emergency repairing with time limited. A dynamic navigation experiment with 30 cross-regional harvesters in June 2010 shows that the new dynamic navigation technology can fulfill the harvesters' needs of monitoring dispatching, emergency repairing and information service, and the system can provide good information service for the management of harvester groups, as well as the operation and transferring of a single harvester.; EI; 0
