The method of calculating the distance between the rear of the car and the parked car in the operation of shunting the top of the car

Abstract

The present disclosure relates to a method for calculating the distance between the rear of a vehicle and a parked vehicle in a shunting top-feed operation, wherein the shunting top-feed operation system includes shunting group members, shunting positioning equipment, an intelligent shunting server, and a laser emission Devices, locomotives. The shunting positioning equipment includes a shunting handheld station, a laser receiving device, and a retractable rod. The shunting handheld station includes a GPS positioning module; the locomotive includes a locomotive controller, a locomotive GPS positioning module, and a laser range finder. When the parking vehicle is located in a closed parking lot, the GPS positioning accuracy decreases. By enabling the laser positioning system, the GPS positioning information is corrected and the positioning accuracy of the parking vehicle is improved. Further, considering that the interference of the laser range finder is relatively large, the laser range finder is only activated after it is determined that the rear of the vehicle enters the straight segment and the distance between the rear of the vehicle and the parked vehicle is less than the threshold value, thereby greatly improving the accuracy of the laser ranging, and then Realize the precise control of the deceleration of the vehicle during the roof transfer operation.

Description

technical field [0001] The present disclosure relates to a railway wireless shunting operation system, and more particularly, to a method for calculating the distance between the rear of a vehicle and a parked vehicle in a shunting top feeding operation. Background technique [0002] The traditional railway wireless shunting operation is mainly performed by the members of the shunting group using the walkie-talkie to send voice and shunting signaling to the locomotive controller in the driver's cab in the form of voice and control signaling. The timing of sending the control signaling is based on the shunting The team members' judgment on the actual situation of the shunting operation. For example, in the shunting operation, the distance signals of the tenth, fifth and third trains are standing at the front of the top delivery vehicle, that is, the members of the shunting group at the rear of the train observe the distance from the car parked in front of the train to give th...

Problems solved by technology

[0011] The present disclosure provides a method for calculating the distance between the rear of the vehicle and the parking vehicle in the top delivery operation of the shunting vehicle, so as to solve the problem of reduced positioning accuracy when the shunting crew members carry GPS positioning modules to locate the parking vehicle under special circumstances. And when the train is moving non-straight, the calculation error of the rear position increases
