Problems solved by technology

At the same time, there are also shunting systems based on satellite positioning systems such as GPS / Beidou. However, due to the characteristics of satellite positioning, there are defects such as relying on differential positioning stations, catenary occlusion, and positioning cycles that do not meet the requirements of vehicle linkage, which cannot be adapted to freight shunting stations. the actual needs of

Embodiment 1

[0055] see figure 1 , the present invention provides a method for shunting and organizing railway freight vehicles based on UWB positioning technology, the method comprising the following steps:

[0056] S1: When the locomotive and the vehicle to be marshaled enter the positioning area, obtain the time when the pulse signal transmitted by the positioning tag arrives at each positioning base station;

[0057] S2: Obtain the coordinates of each positioning base station;

[0058] S3: Obtain the coordinates of the positioning tag according to the time when the pulse signal transmitted by the positioning tag arrives at each positioning base station and the coordinates of each positioning base station;

[0059] S4: Carry out shunting and grouping according to the coordinates of the positioning tags.

[0060] In step S3, the coordinates of the positioning tag are obtained according to the time when the pulse signal transmitted by the positioning tag arrives at each positioning base...

Embodiment 2

[0133] see image 3 , the present invention provides a railway freight vehicle shunting and marshalling system based on UWB positioning technology, the system includes:

[0134] Several positioning base stations, UWB engine servers, positioning tags and control centers;

[0135] Wherein, several positioning base stations are arranged around the freight station for receiving pulse signals transmitted by positioning tags;

[0136] The positioning tag is matched and installed on the locomotive head and the vehicle to be formed, and is used to transmit pulse signals, and the positioning tag has a unique ID mark;

[0137] Several positioning base stations connect and communicate with the UWB engine server deployed in the control center through the communication base station;

[0138] According to the positioning data sent by the positioning base station through the communication base station, the UWB engine server deploys and configures the positioning acquisition program and the...

Abstract

The invention relates to a railway freight vehicle shunting marshalling method and system based on a UWB positioning technology, and the method comprises the following steps: obtaining the time when a pulse signal transmitted by a positioning tag arrives at each positioning base station; obtaining coordinates of each positioning base station; obtaining the coordinate of the positioning label according to the time when the pulse signal transmitted by the positioning label arrives at each positioning base station and the coordinate of each positioning base station; and shunting marshalling is carried out according to the coordinates of the positioning labels. The real-time positions of the locomotive and the vehicle can be obtained in real time, when the locomotive approaches to the to-be-grouped vehicle, the real-time position is fed back to the locomotive cab in real time, it is guaranteed that the vehicle hanging speed is lower than the set range, and shunting safety is guaranteed.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a method and system for shunting and organizing railway freight vehicles based on UWB positioning technology. Background technique [0002] The marshalling of freight marshalling yards has long used manual planning. Even if information software is used, it is only manual planning, real-time printing of transfer orders, and the location and trajectory information of vehicles and inspection and maintenance personnel cannot be obtained in real time. Freight trains will be parked on the track according to the schedule, and the number of parked tracks and numbers will change at any time according to the schedule. The inspectors will also inspect the designated trains during the specified time period and route to check the train situation. Therefore, there is an urgent need for automatic acquisition and management of locomotive and vehicle location information. At the same time, ...
