Abstract

The invention relates to a double-main-control device and a main-standby control method, and the double-main-control device comprises a first main control board and a second main control board. The primary main control board in the first main control board and the second main control board is used for monitoring a first software state of the primary main control board and a second hardware state of the standby main control board in the first main control board and the second main control board; the standby main control board is used for monitoring a second software state of the standby main control board and a first hardware state of the primary main control board; and if at least one of the first software state and the first hardware state of the primary main control board is abnormal and the second software state and the second hardware state of the standby main control board are normal, main-standby switching is performed on the primary main control board and the standby main control board. According to the invention, the main / standby switching can be quickly carried out, and the normal work of the whole system is ensured.

Description

technical field [0001] The present application relates to the field of equipment control, in particular to a dual-master control equipment and a master-standby control method. Background technique [0002] In a high-reliability application environment, there are high requirements for the reliability of the equipment. When the equipment has a single point of failure in hardware and software, the entire equipment can still work reliably; for this reason, the main control board of the equipment usually uses 1 +1 hot standby method; that is, one control board is in master (active) at the same time, and the other control board is in slave (standby). However, in the prior art, the active and standby main control boards are respectively equipped with independent CPUs. Therefore, how to quickly perform active and standby switchover when the active main control board fails is an urgent problem to be solved. Contents of the invention [0003] The present application provides a dual...
