The switchback method based on the fully automatic operation system and the remote switchback method

Abstract

The invention provides a turn-back terminal exchanging method and a remote turn-back terminal exchanging method based on a full-automatic operation system. The turn-back terminal exchanging method includes the steps that a control terminal VOBC inspects whether the position of a train meets a turn-back line condition or not, if the position of the train meets the turn-back line condition, the control terminal VOBC continuous inspects whether the train meets an FAM mode turn-back condition or not, if the train meets the FAM mode turn-back condition, an FAM mode turn-back terminal exchanging mark is set to be effective, emergency braking EB is output, meanwhile, a turn-back canceling command is sent to a ZC, whether a turn-back canceling confirmation command fed back by the ZC is received within a designated time period or not is judged, and if the turn-back canceling confirmation command is received with the designated time period, an AR relay is controlled to descend, otherwise it is confirmed that turn-back operation fails; and a waiting terminal VOBC receives an FAM mode operation level of the control terminal VOBC and inspects whether the waiting terminal VOBC meets a turn-backterminal exchanging condition or not, if the turn-back terminal exchanging condition is met, an FAM mode is output to the train, an AR relay of the waiting terminal VOBC is attracted up, and turn-backterminal exchange is finished. By the adoption of the provided turn-back terminal exchanging method, automatic turn-back terminal exchange can be finished without artificial participation under the condition that the turn-back condition is met.

Description

technical field [0001] The invention relates to the field of rail traffic control, in particular to a method for turning back and changing terminals based on a fully automatic operation system and a method for remote turning and changing ends. Background technique [0002] In the traditional CBTC system operation, the turn-back scenarios are mainly divided into turn-back before the station (such as figure 1 , figure 2 as shown) and turning back after the station (as shown in image 3 shown). Among them, turning back after the station can realize unmanned turning back according to the line conditions (such as Figure 4 shown). In the operation of the traditional CBTC system, no matter whether it is turning back before the station, turning back after the station or no one is turning back, it needs the cooperation of the driver to complete. [0003] In the operation of the traditional CBTC system, the driver needs to press the AR button to confirm the start of the turn-ba...

AI Technical Summary

Problems solved by technology

[0004] The GOA4 operation mode of the fully automatic operation CBTC system is defined as an unattended operation mode, so the above-mentioned existing return method is not applicable in the fully automatic operation of the CBTC system GOA4 operation mode

[0005] In the operation of the traditional CBTC system, the driver must drive and cooperate to complete the switchback and switchover. It is impossible to realize the automatic switchback and switchover of the equipment. Usually, in the manned driving mode, one or two drivers are equipped. If there is one driver, the driver needs to switch between switchbacks. After pressing the reentry button during the reentry process, quickly walk to the other end and turn on the key to complete the reentry process. To complete the reentry process, the driver’s reaction time is 2 seconds, and the driver’s passing time from one end to the other end is 30s. It takes at least 32s to complete the reentry process; If two drivers are equipped, the driver’s reaction time*2 is about 4s to complete the turn-back process

[0006] In the operation of the traditional CBTC system, if there is an operation change operation, the central dispatcher needs to change the route in advance so that the VOBC can turn back successfully; if the car has entered the turn-back area and has not gone through the turn-back route, the driver must manually change the route The terminal is completely changed, and automatic terminal switching cannot be realized.
