Serial port based management system and management method

Abstract

The invention provides a serial port based management system and management method. The management system comprises a main control card, a back plate and a plurality of service cards, wherein the back plate is communicated and connected with the main control card through a serial port bus; the service cards are communicated and connected with the back plate through a serial port bus and are communicated with the main control card through a serial port bus; and the plurality of service cards are communicated with the main control card according to a set protocol. The instruction communication between the main control card and the service cards is realized; only two serial port bytes are needed for completing one instruction; the efficiency is high; the set protocol is simple and compact; the service cards can be realized by a state machine of a programmable logic module; and the reliability is high.

Description

technical field [0001] The invention relates to the field of system equipment management, in particular to a serial port-based management system and management method. Background technique [0002] In the data communication system equipment, the frame-type multi-service board design is often used to meet the flexible configuration of services and expansion requirements, and the service cards are connected to each other through the backplane. In terms of functions, there are generally three types of signals on the backplane: high-speed and large-volume business signals, medium-speed and medium-volume protocol processing signals, and low-speed and low-volume board management signals. [0003] For low-speed and low-data board management signals, multi-channel logic signals or serial ports are usually used to process them because of their small data volume and high reliability requirements. There are following two schemes in the prior art: [0004] Scheme 1 is a multi-channel ...
