Railcar shunting operation protection method

Abstract

The invention discloses a railcar shunting operation protection method. The method mainly comprises the steps of remote automatic updating of car-mounted equipment software and a station map through aGMS platform, realization of a remote return function for fault information, running state information, running position information and running record files of car-mounted equipment, and remote transmission of comprehensively processed safety protection car control information through a railcar. A shunting operation protection service platform carries out comprehensive processing according to high-precision positioning information of the railcar, information of the station map and route information obtained after analysis to obtain safety protection control information required for shuntingoperation; the safety protection control information is transmitted to the railcar car-mounted equipment in real time through the GMS platform, anti-overrunning, anti-overtaking and anti-collision functions of the railcar during shunting are achieved, the problem that current railcar shunting operation lacks effective technical protection means can be solved, and the safety risk of the shunting operation is reduced.

Description

Technical field [0001] The invention relates to the technical field of traffic and transportation signal control, in particular to a rail car shunting operation protection method. Background technique [0002] As an important part of railway transportation production, shunting operation is a highly technical, demanding and complex task in station transportation. As the signal status during the shunting operation mainly relies on the manual confirmation of the driver and the shunting crew, accidents such as "rushing, squeezing, and falling off" occur from time to time, posing a serious threat to transportation safety. On June 13, 2018, the railcar shunting operation of the Ankang Public Works Section ran to the front of the switch-off section blocking the D218 signal. The driver did not find the closed D218 signal (showing blue light). After crossing the D218 signal, the driver found the front The 230# turnout was turned on the reverse position, and emergency braking was used (no...

Problems solved by technology

However, the system includes station ground equipment and on-board equipment. Each station needs to build a set of ground equipment, which is relatively expensive, and the ground and on-board equipment use digital radio wireless communication, which is limited by the transmission power of the radio station. Due to the limitation of allocated frequency points, the number of locomotives allowed to access the network is limited; in addition, the positioning technology and positioning accuracy adopted by the system need to be improved

At present, there is no reliable technical prevention equipment for rail car shunting operations, and the lack of safety protection measures for shunting operations has caused safety hazards such as running blue lights, squeezing switches, going out of station boundaries, and destroying access roads during shunting operations.
