Neutral-section passing control method, device and system

Abstract

The invention discloses a neutral section passing control method, a neutral section passing control device and a neutral section passing control system. The method comprises the following steps: employing a state machine program to control logic, wherein the program has a waiting state machine, a forward neutral section-enter state machine, a forward commutation state machine and a forward neutralsection-exit state machine; when the position information of a train is that the train forwardly passes through a preset neutral section-enter control point, skipping to the forward neutral section-enter state machine, and executing a control action of switching off a second switch and switching on a first switch; when the position information of the train is that the train forwardly passes through a preset commutation control point, skipping to the forward commutation state machine, and executing a control action of switching off the first switch and then switching on the second switch; andwhen the position information of the train is that the train forwardly passes through a preset neutral section-exit control point, skipping to the forward neutral section-exit state machine, and executing a control action of switching off the first switch and switching off the second switch. By using the method, the train neutral section passing control can be conveniently carried out, the returning special condition of the train in the neutral section region can be conveniently controlled, the flexibility and the stability are good, and an expansion process is convenient.

Description

technical field [0001] The present invention relates to the technical field of excessive phase separation, in particular to a method, device and system for controlling excessive phase separation. Background technique [0002] At present, the phase separation of electrified railways in my country is mainly based on the automatic phase separation when the train is powered off and the automatic phase separation when the ground circuit breaker is switched. The main problems of the automatic over-phase separation of the train power failure are: the labor intensity of the train driver, the frequent action of the on-board circuit breaker leads to the limited service life, and the large speed loss to the train during the power failure process, resulting in limited train transportation capacity. There are also problems such as frequent circuit breaker actions and large transformer surge current and overvoltage at the moment of circuit breaker switching. Therefore, the popularization...

Problems solved by technology

The main problems of the automatic over-phase separation of the train power failure are: the labor intensity of the train driver, the frequent action of the on-board circuit breaker leads to a limited service life, and the large speed loss is brought to the train during the power failure process, resulting in a limited train transportation capacity

However, no in-depth research has been done on the situation where the train needs to turn back due to abnormal working conditions in the phase-splitting area. This scheme proposes a train turn-back control method with excessive phase separation. The control system is as follows figure 1 As shown, the control system uses the train position recognition system to identify the position of the train pantograph, the direction of the train and the position of the train in the phase-splitting area. , control the opening and closing of the A-phase switch QF1 and the B-phase QF2, realize the return of the train at any position in the phase-splitting area, ensure the safety of the locomotive, and prevent the phase
