Method and system for controlling automatic route selection on railway vehicle

Abstract

The invention relates to automatic route selection technology for a railway vehicle. In a method and a system for controlling automatic route selection of the invention, a microelectronic module is adopted to replace the prior relay, the logical relation is completed by an MCU, and the logical design is simpler and more reliable; a wireless remote control mode is introduced to complete the opposing change of a railroad switch, so the work intensity of a driver is reduced; electromagnetic sensing technology is quoted to determine the direction and speed of a train; and a remote integrated monitoring function is increased to master the work states of equipment such as an electric point switch, a railroad switch, a wheel sensor and the like at any time. Therefore, the new functions improve the running safety of the train greatly, ensure the stability of the equipment, and really achieve automatic route selection of the train.

Description

technical field [0001] The invention relates to the technical field of route control on a railway car, in particular to the self-selected route control technology on a railway car. Background technique [0002] Interlock centralized control [0003] State-owned railway train operation control at home and abroad implements a multi-professional joint operation mode with a clear division of labor, and adopts a computer interlocking centralized control method that matches the mode. The railway signal computer interlocking centralized control system is a set of high reliability and high Safety control system. The railway station interlocking equipment controls the signal equipment installed on the station, turnouts and track circuits in an interrelated manner, and establishes a safe running route for the trains running at the station. The system centralizes the control of the railway network (a station composed of multiple railway lines or a railway network composed of multiple...

AI Technical Summary

Problems solved by technology

[0009] 1. The function of the computer interlocking control system is not perfect, the power consumption is high, the cost is high, and the floor area is large. Usually, a station area needs a signal building to store relays and other equipment

The factory-mine railway is affected by factors such as site area and environment, so it is not suitable to use computer interlocking control

[0010] 2. Once a hardware failure occurs in the interlocking computer that implements the interlocking logic in the computer interlocking control system, it will have a great impact and even make the system unable to work

[0013] The relay interlocking technology used in the on-board switching control technology requires the use of various types of relays, so the control box of the on-board switching device is bulky, and the control box is placed along the railway line. When the train passes by, the relay is likely to vibrate and the relay contacts will appear. Poor contact phenomenon; relay interlocking technology cannot realize the intelligent monitoring of turnouts, cannot judge whether the turnout switching request is reasonable, cannot record the driving direction and route of the train, cannot distinguish the turn-back operation, and the switch between the tip rail and the basic rail during the switching process Foreign objects in between cannot automatically request the turnout to return to its original position, so it cannot prevent the derailment accident caused by the cross operation of two vehicles or the second misoperation, which will bring great safety hazards

[0014] 2. On-vehicle conversion control technology cannot monitor the status of equipment such as switch electric switch machines in real time

Due to the lack of monitoring of equipment status in the non-centralized interlocking control area, it is impossible to "foresight" the equipment failure, and the equipment failure cannot be reflected to the maintenance personnel at the first time, so the safety protection performance of the on-board conversion technology is greatly reduced

[0015] 3. The protection area of ​​the entire turnout is only in one turnout section. As long as the train does not enter the turnout section, other operating positions (operation lever, operation button, forward switch) can switch the turnout again, so it is safe for the train to run. Brings great potential safety hazards, prone to train derailment accidents

[0016] 4. Driving safety is basically guaranteed by the low-speed operation of the train, and the driving efficiency is greatly restricted
