Processing method for ATP automatically passing through neutral zone

Abstract

The embodiment of the invention discloses a processing method for an ATP automatically passing through a neutral zone. The processing method comprises the steps that when a vehicle-mounted ATP passesthrough an entrance ahead transponder, an entrance ahead signal about to enter the neutral zone sent by the entrance ahead transponder is received, an enable signal that the ATP automatically passes through the neutral zone is sent to a vehicle, after an enable feedback signal that the ATP automatically passes through the neutral zone and which is fed back by the vehicle is received, a feedback signal is sent to the vehicle-mounted ATP, after the traction is cut off, coasting is started and a main circuit breaker is disconnected, so that a train coasts to pass through the neutral zone. The entrance ahead transponder, an exit ahead transponder and a neutral zone protective annunciator are arranged on the trackside, neutral zone forecasting is carried out in advance, it is ensured that the train has a certain speed value before reaching the neutral zone, it is achieved that the train automatically coasts to pass through the neutral zone, the situation that the train parks on a nonelectric zone of the neutral zone is avoided, the working strength of drivers and scheduling personnel is reduced, and the comfort of 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 an ATP automatic phase separation processing method. 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 Regulations" that Double-b...

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
