Track-side signal equipment system for ATP to automatically pass through neutral section

Abstract

The embodiment of the invention discloses a track-side signal equipment system for an ATP to automatically pass through a neutral section. The track-side signal equipment system comprises an entranceprewarning transponder, an exit prewarning transponder and a neutral section protection semaphore. The entrance prewarning transponder is arranged at a first preset distance in front of a prewarning point. The exit prewarning transponder is arranged at a second preset distance behind the neutral section; the neutral section protection semaphore is arranged at a third preset distance in front of the neutral section. By arranging the entrance prewarning transponder, the exit prewarning transponder and the neutral section protection semaphore on the side of a track, pre-warning of the neutral section is given in advance, the train is ensured to have a certain speed value before arriving at the neutral section, so that the train can automatically pass through the neutral section inertia, the situation that the train stops in a area without electricity of the neutral section is avoided, the working intensity of the driver and the dispatcher is reduced, and the comfort of the passengers is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of rail transit, and in particular to a trackside signal equipment system for ATP automatic cross-phase separation. Background technique [0002] The phase separation area refers to the catenary non-electrical area between the two power supply partitions of the AC traction electrification section. Because the catenary-pantograph-train-rail forms a complete current loop, and the current direction between adjacent power supply partitions is opposite, one is A-phase electricity, and the other is B-phase electricity, if the rolling stock at this time The pantograph connected to two power supply partitions at the same time is equivalent to a phase-to-phase short circuit, which can easily cause serious accidents such as tripping of the substation, breakdown of the locomotive transformer, and even collapse of the catenary. Therefore, it is stipulated in the "Railway Locomotive Operating Re...

Problems solved by technology

However, during the automatic phase separation process of the vehicle, since the signal system does not participate in the control of the train speed, but the vehicle system itself controls the train, if the train speed is low when the traction is cut off, it is very likely that the train will stop at the phase separation due to inertia If there is no electricity in the area, if this happens, the driver needs to report to the control center, and the dispatcher will assist the power supply in the phase-separated area to realize the restart of the train. This method is complicated to operate, consumes manpower and affects the driving efficiency
