SPKS switch, interlocking system and use method of interlocking system

Abstract

The invention discloses an SPKS switch, an interlocking system and a use method of the interlocking system. The SPKS switch comprises starting assemblies and closing assemblies of the SPKS switch and control assemblies, wherein the starting assemblies and the closing assemblies are arranged in all platform monitoring rooms in the interlocking system, and the control assemblies are arranged on all platforms and used for locking or unlocking physical sections of the platforms. The starting assemblies and the closing assemblies are in communication connection with the control assemblies. The starting assemblies are used for starting the control assemblies to lock the physical sections of the platforms. The closing assemblies are used for making the control assemblies unlocking the physical sections of the platforms. The interlocking system comprises the platform monitoring rooms and the SPKS switch for locking the platforms. According to each platform, the corresponding starting assembly and the corresponding closing assembly of the SPKS switch are arranged in the corresponding platform monitoring room, and the corresponding control assembly of the SPKS switch is arranged on the corresponding physical section of the platform. By the adoption of the SPKS switch applied to the interlocking system, potential safety hazards caused by train stopping due to unsolvable faults occurring when a train travels in the sections in a CBTC system are eliminated.

Description

technical field [0001] The invention relates to the field of signal control, in particular to an SPKS switch, an interlock system, and a method for using the interlock system. Background technique [0002] In the existing CBTC (Communication Based Train Control), the rear vehicle can track the front vehicle, and the rear vehicle and the front vehicle can run in the same section. When the front train has a serious failure in the section, the driver and the station dispatcher will cooperate to make the train run to the next station at a temporary speed limit or the lowest speed, so as to carry out operations such as passenger clearance and maintenance. Although the rear vehicle can track the front vehicle, the MA (Movement Authority) of the rear vehicle is always placed at the rear of the front vehicle, and manual operation and confirmation can ensure the safety of train operation. [0003] However, under the fully automatic driving CBTC system, since there is no driver on th...

AI Technical Summary

Problems solved by technology

[0003] However, under the fully automatic driving CBTC system, since there is no driver on the train, there will be fewer dispatchers at the station. When a serious fault occurs in the preceding train in the section, the train will only brake urgently, and cannot relieve the brake, and cannot recover from the fault. To leave the section, the driver needs to go down to the section and get on the train to manually control the train

If the vehicle behind still follows the vehicle in front according to the operating rules of the CBTC system, it may cause danger to the intervening driver, and it is not conducive to the driver to drive the faulty train back to the previous station. Waiting too long in the interval, causing more passengers to panic

[0004] If the rear vehicle receives the failure information of the front vehicle from the ground interlock subsystem at the station (usually the ground interlock subsystem lock section), the station can also impound the rear vehicle so that the rear vehicle cannot enter Section to the faulty train

However, if the rear vehicle has left the station, the station will lose control of the rear vehicle, and the rear vehicle will enter the section, either causing maintenance personnel and emergency drivers to fail to enter the section, or causing safety hazards to maintenance personnel and emergency drivers

[0005] For this reason, the existing manned CBTC system is not suitable for the scene requirements of fully automatic driving train failures, which will cause troubles for fault maintenance in fully automatic driving
