Main circuit breaker redundancy control circuit and train

Abstract

The embodiment of the invention discloses a main circuit breaker redundancy control circuit. The circuit is characterized in that the control circuit comprises a controller, a main circuit breaker switch, an emergency mode switch, a network control module and a main circuit breaker relay winding, wherein the controller is used for detecting whether the function of the network control module is normal or not, if not, closing the emergency mode switch, switching on an access where the emergency mode switch is located, enabling the network control module to be short-circuited, and enabling the main circuit breaker relay winding to be electrified through the access where the emergency mode switch is located when the main circuit breaker switch is closed. Through the circuit, the network modulecan be short-circuited when a network module fails, and the relay winding of the main circuit breaker is directly electrified through the main circuit breaker switch, so redundancy control of the main circuit breaker is realized.

Description

technical field [0001] The present application relates to the technical field, and in particular to a main circuit breaker redundant control circuit and a train. Background technique [0002] The circuit breaker is an important part of the train control link. Whether the main circuit breaker can be accurately controlled is one of the important factors to keep the train running stably. [0003] In the related art, the control of the main circuit breaker is performed through the main circuit breaker switch and the network control module. This control method has a low fault tolerance rate and is prone to control failure. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems, the present application provides a redundant control circuit of the main circuit breaker, which can be short-circuited when the network module fails, and the relay winding of the main circuit breaker can be directly energized through the main circuit breaker switch, so as to rea...
