Abstract: For the problems of vehicle scheduling system of open-cut based on GPS,such as high energy consumption of user node,big volume and high cost and need fixed infrastructure, the paper discussed on feasibility of applying WSN in vehicle scheduling system of open-cut. It analyzed key technologies used in vehicle scheduling system of open-cut based on WSN, pointed out the positioning technology is a precondition of applying WSN in vehicle scheduling system of open-cut successfully, and introduced a positioning algorithm which is adapted to vehicle scheduling system of open-cut and implementation method of target positioning. Finally, it gave application prospect of the system.
