Abstract

The invention discloses a railway plane wireless shunting positioning method, which comprises the following steps of estimating the position of a current locomotive according to the position of the locomotive at the previous moment, and judging the accurate position of the locomotive according to a shunting section by combining measurement data of the position of the locomotive. Based on the method, the invention further discloses a railway plane wireless shunting system which comprises a warden station controller, a locomotive station controller, a handheld radio station and a cloud server. According to the invention, digital wireless communication is adopted; a shunting signal channel is kept unblocked; a positioning device is carried in the locomotive platform controller; the algorithmimprovement is carried out on the detection result of the positioning device; in the shunting process, accurate positioning of the rolling stock is realized, and the shunting process is displayed on the mobile and computer client through the cloud server. The operation complexity of shunting operation is simplified, the energy of operators is saved, the shunting accuracy is improved, the safety ofshunting operation is enhanced, and shunting accidents caused by personnel negligence are avoided.

Description

technical field [0001] The invention relates to the technical field of railway shunting, in particular to a railway plane wireless shunting positioning method, a shunting system and a working method thereof. Background technique [0002] Railway plane shunting, as the primary link in railway operation, is the shunting operation carried out on the plane pull-out line. The completion of the plane shunting task is the first step to ensure that the train runs on the corresponding track and the accurate delivery of personnel and goods. The railway level wireless shunting system is based on the addition of control software and hardware to radio stations, real-time transmission of vehicle marshalling information, and an information and control system for vehicle marshalling scheduling that integrates communication and signal integration of light display signaling and voice prompts. [0003] The existing railway plane wireless shunting system has the following three disadvantages: ...
