Abstract

The invention provides a dual-central processing unit (CPU) hot standby redundancy control method and device of a braking control unit of a brake. The dual-CPU hot standby redundancy control method isapplied to a master control CPU and comprises the steps of triggering the master control CPU to be switched from a current control state to a non-control state under the condition that a predetermined type of working fault which is already generated by the master control CPU is determined or the master control CPU which is already in response to a switching request of an auxiliary control CPU isdetermined; and judging whether the master control CPU is successfully switched to the non-control state within preset switching frequency or not, and forcing the master control CPU to be switched tothe non-control state if the master control CPU is not successfully switched to the non-control state within the preset switching frequency. According to the method provided by the embodiment of the invention, the master control CPU can be repeatedly triggered to be switched from the control state to the non-control state or the master control CPU is forced to be switched to the non-control statewhen the master control CPU is needed to stop controlling a corresponding function, the control state of the master control CPU is reliably removed, and the safety of braking operation of the brake isimproved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a dual-CPU hot standby redundant control method and device for a braking control unit of a brake. Background technique [0002] With the rapid development of rail transit, the safety performance of trains is also facing new challenges. The train brake is one of the key components to ensure the safety of train operation. Among them, the brake control unit of the brake plays an important role in the accurate braking control of the brake. The brake machine executes the brake operation according to the control signal sent by the brake control unit. [0003] The CPU in the brake control unit is the central module for the brake control unit to perform corresponding functions and send out control signals accurately. In order to maintain the normal operation of the brake control unit and ensure the correct braking operation of the brake machine, in the prior art, two CPUs ca...
