Shunting service risk control system

Abstract

The invention provides a shunting service risk control system which comprises a train which prepares to perform shunting service in a station yard, a vehicle-mounted detection device arranged on the train, a vehicle-mounted train prevention and control master control device, a vehicle-mounted high-precision positioning device, a ground train prevention and control master control device and a ground high-precision positioning device which are arranged in the station, and a train operation dispatching command system (TDCS) and a transportation management information system (TMIS) which are connected with the ground train prevention and control master control device. According to the system, the train position information acquired by the detection, blue and white lamp and track occupancy information and preset information in the TDCS system are subjected to error correction and comparison, so that the train is correspondingly controlled, and the train safety in the process of performing shunting service is guaranteed.

Description

technical field [0001] The invention relates to a control system, in particular to a shunting operation risk control system. Background technique [0002] The blue and white light is the train signal display light in the station yard shunting operation. The trains at the station are shunted according to the blue and white lights. The shunting blue and white light signal machine displays the following signals: [0003] 1) White light: It is permitted to shunt vehicles across the signal; [0004] 2) White flashing lights: when equipped with a flat discharge centralized equipment, the slip and discharge shunting is allowed; [0005] 3) Blue light: It is not allowed to cross the signal to switch trains. [0006] Specifically, the white light state: (equivalent to "green light") allows trains to cross the signal machine, and the blue light state (equivalent to "red light") does not allow trains to run; currently domestic identification of blue and white light signals mainly d...

Problems solved by technology

[0006] Specifically, the white light state: (equivalent to "green light") allows trains to cross the signal machine, and the blue light state (equivalent to "red light") does not allow trains to run; currently domestic identification of blue and white light signals mainly depends on drivers or The station staff visually inspected, so there is a hidden danger in driving

In the process of shunting, it is easy to cause accidents such as rushing, squeezing, and falling off, which poses a serious threat to the safety of railway transportation.

[0007] The shunting conflicts, shunting derailment, crowded turnouts, and vehicle slippage that occur in daily shunting operations are directly related to relying on manual monitoring. When the signal machine has no display, the display is unclear, or the display is incorrect, it is very easy to cause accidents , endangering the safety of trains and personnel. In addition, some domestic methods adopt the method of adding track circuits, but their applicability is poor, and even some insulation partitions are extremely short. , because its track circuit is very short, it is also unable to receive the blue light information according to the distance that the train should be protected from the blue light

Some schemes are only implemented for the shunting yard, but there is still no mature scheme for all stations on the whole road, and the real-time performance of the signal reflection is poor, the positioning accuracy of the train vehicle is very rough, or the speed acquisition and analysis system of the train itself is used, resulting in unclear judgments There will also be accumulated errors in the length direction of the stock track, which makes it difficult to determine the exact position of the train, and cannot be used for blue and white light recognition and driving control
