Shunting automatic protection system and automatic shunting method

Abstract

The invention discloses a shunting automatic protection system. At least two ground devices are arranged between a front shunting signal machine and a back shunting signal machine of each station track. The ground devices collect shunting state signals of the shunting signal machines and engine driving state signals and send the collected signals to an engine device. The signals are sent to a train control device after being processed by the engine device. The shunting automatic protection system has the advantages that shunting signal machine states and current positions can be acquired timely and accurately when the front end of a car row or the back end of the car row is close to the shunting signal machine for certain distance. Current positions of the front end of the car row or the back end of the car row can be acquired timely and accurately when the front end of the car row or the back end of the car row is close to a blind siding bottom gear position for certain distance. The shunting signal machine states and the positions of the front end of the car row or the back end of the car row are sent to a train control device timely so as to provide conditions for forced automatic stop movement taken by the train control device.

Description

technical field [0001] The invention belongs to the field of railway shunting operations, and in particular relates to a shunting safety protection system and an automatic shunting safety protection method based on the system. Background technique [0002] Shunting operation is an integral part of railway traffic work. A large number of shunting operations are carried out every day in marshalling yards, section stations, freight stations, passenger stations and some intermediate stations. For a long time, the shunting work has followed the traditional operation method, using hand signals to command the shunting operation. Once a problem occurs, the equipment cannot be controlled. Although relevant departments have adopted various countermeasures to strengthen the safety of shunting vehicles and prevent shunting accidents, the total number of shunting accidents has decreased, but it is still difficult to completely eliminate them. According to statistics, the number of shunt...

Problems solved by technology

However, when the locomotive is in the propulsion operation, the locomotive is at the rear of the train, and the locomotive crew cannot directly look at the status of the signal machine, and can only rely on the front-end shunting staff to pass the front information to the locomotive crew in time

[0006] (3) The plane shunting light display system relies on the front-end shunting staff to visually or estimate to obtain the front status information, and then sends instructions (voice or light display) through the radio station to guide the locomotive crew to perform corresponding operations. Since the radio stations are susceptible to interference, so Causes the received information to be inaccurate, resulting in misoperation

[0007] (4) The combination of plane shunting system and LKJ device used in some areas has the protective function of automatic parking, but the equipment cannot automatically obtain ground information, and it is still based on the manual instructions of the locomotive crew or shunting personnel

[0008] (5) The shunting monitoring system adopted by some stations realizes the real-time transmission of ground access status to locomotive train control equipment, and can intuitively display the opening of access routes and the occupancy of surrounding lines to locomotive crew and train control equipment. It is difficult for the control equipment to accurately grasp the current position of the front end of the train, and the operation complexity of the locomotive crew is greatly increased

Therefore, it is difficult to truly achieve effective protection
