Software and hardware cooperative control self-management main and standby switching method

Abstract

The invention discloses a software and hardware cooperative control self-management main and standby switching method, which relates to main and standby switching of a main control board of digital multiplexing and demultiplexing equipment and comprises a CPU (central processing unit) module, an FPGA (field programmable gate array) module, an Ethernet interface, an Ethernet switching module and the like. According to the invention, the main and standby switching of the multiplexer main control board is realized; a special management control unit is not needed, and self-management is realized by the main control board; the FPGA and the CPU realize software and hardware cooperative control to realize master-slave switching, and the switching function can be completed under the condition that a master control CPU program is abnormal; the main and standby switching does not need to plug a cable and replace a maintenance management IP address; the multiplexing and demultiplexing parameters of the main and standby main control boards are updated synchronously, the service multiplexing and demultiplexing are carried out simultaneously, and the influence of main and standby switching on the current service transmission is small. The method is suitable for the digital multiplexer / demultiplexer with high reliability requirements.

Description

technical field [0001] The present invention proposes a self-management active-standby switching method of software and hardware cooperative control, which mainly solves the problem of digital multiplexers with high task reliability requirements. Backup switching problem. Background technique [0002] The main control board is the core processing unit board of the multiplexer, which completes the multiplexing of various services and the maintenance and management of equipment. The 1:1 redundancy design of the main control board can effectively improve the task reliability of the equipment. When the main main control board fails, the equipment will automatically switch to the standby main control board to ensure the normal operation of the equipment. [0003] Most of the current active / standby switching technologies are controlled by a dedicated management control unit, which increases the complexity of equipment implementation; the redundantly designed unit boards work inde...

AI Technical Summary

Problems solved by technology

[0003] Most of the current active / standby switching technologies are controlled by a dedicated management control unit, which increases the complexity of equipment implementation; the redundantly designed unit boards work independently, and maintenance cables need to be plugged from the active board to the original The standby board realizes the equipment management after the master-standby switchover; some master-standby switchovers are managed and controlled by the processor of the redundant design unit, if the processor program fails, the master-standby switchover cannot be completed
