Heavy haul train neutral section passing control method and system

Abstract

The invention relates to a heavy haul train neutral section passing control method and system. The method comprises the following steps that S1, vehicle-mounted equipment obtains the speed, the position and the running direction of a train through a speed and distance measuring unit; S2, the vehicle-mounted equipment acquires neutral section passing information through a wireless transmission unit and a transponder receiving unit before a neutral section area; S3, the vehicle-mounted equipment draws a speed curve according to the neutral section passing information and the train speed and position information; and S4, the vehicle-mounted equipment completes neutral section passing according to the speed curve. Compared with the prior art, the method has the advantages of high safety, high efficiency, high precision and the like.

Description

technical field [0001] The invention relates to the field of over-phase separation of rail transit trains, in particular to a control method and system for over-phase separation of heavy-duty trains. Background technique [0002] Heavy-duty transportation is the mainstream direction of railway freight development. As the quality of trains and the length of marshalling continue to increase, the problems of operational safety are becoming more and more prominent. Serious accidents such as coupler breakage, large longitudinal impulse, and train derailment may occur on some difficult-to-maneuver sections. The electric locomotive of electrified railway adopts single-phase power supply. In order to balance the load of each phase of the power system, the phase sequence rotation power supply is generally implemented, and the electric phase separation is set in the catenary to electrically isolate different phases to avoid short circuit between phases.

Problems solved by technology

[0005] 1) The currently used overphase depends on the driver actively pressing the overphase button according to experience and prompts, disconnecting the main circuit breaker, and cannot realize automatic driving;

[0006] 2) At present, the judgment of over-phase separation is based on the distance to judge whether it has reached the phase-separation area. If the train speed is too low, the train will stop in the over-phase separation area according to the distance;

[0007] 3) At present, the overphase distance is judged according to the kilometer scale provided by the LKJ equipment, which may cause errors to affect the accuracy of the overphase;

However, this utility model does not consider the situation that the speed is too low to pass the phase-separation area; and when leaving the phase-separation area, the acceleration is slow and the operating efficiency is not high
