【 摘 要 】

In order to solve the problem of inaccurate positioning of shunting locomotives by the shunting subsystem of the marshalling yard, this paper proposed a Zigbee shunting locomotive tracking and positioning system based on geographical information of station yards. The system adopted a modular design. The hardware of the lower computer included a coordinator node, a fixed node (routing node) and a vehicle-mounted collector node. This paper used BP (Back Propagation) neural network to fit the nonlinear function of RSSI (Received Signal Strength Indicator) to transmission distance. The research shows that the positioning system proposed in the paper can control the positioning error within 2m. Combined with the geographical information of the station site, the locomotive running position can be displayed on the map of the station yard. It can be a more complete solution to practical problems and has a certain practical value in the field.
