Embodiment 1

[0036] The invention provides a system for reading single board information, which includes a main control board, a backplane and one or more service boards, wherein the main control board at least includes a CPU and a serial bus driver module, and the service board at least includes a memory .

[0037] The CPU on the main control board and the serial bus driver module are connected by a serial interface. The serial bus driver module drives the serial bus interface signal of the CPU into multiple channels. The main control board and the service board are connected through the backplane The serial bus interface signal is driven as a single signal, and one of the driven multiple serial bus interface signals can be used as a dedicated serial bus interface signal for the service board.

[0038] The backplane connects the serial bus interfaces of the main control board and the service board, and provides the slot number signal to the service board to distinguish the boards in diffe...

Embodiment 2

[0052] This embodiment provides a method for reading and writing information on a single board, which can be implemented relying on the above-mentioned system. This method mainly includes the following operations:

[0053] Drive the CPU serial bus interface signal on the main control board into multiple channels, wherein at least one serial bus interface signal is used as a dedicated serial bus interface signal for the service board;

[0054] The CPU on the main control board respectively reads and writes the information of the single board in the memory of each service board through the above-mentioned special serial bus interface signal of the service board;

[0055] Among them, the CPU serial bus interface on the main control board is respectively connected to the serial bus interface of the memory on each service board through the backplane, and at the same time, the backplane provides the service board slot number signal to the memory on each Storage of service boards in...

Abstract

The invention discloses a system and method for realizing reading and writing of single-board information, and belongs to the field of electronic communication. The system at least comprises a master control board, a backboard and one or more business boards, wherein the master control board at least comprises a CPU and a serial bus interface driving module; each business board at least comprises a memory; the serial bus interface driving module on the master control board is used for driving serial bus interface signals of the CPU on the master control board into a plurality of paths; one path of the serial bus interface signals are singly used as dedicated serial bus interface signals of the business boards; the CPU on the master control board is used for carrying out read-write operation on single-board information in the memory on each business board through the dedicated serial bus interface signals of the business board; and the backboard is used for connecting a serial bus interface of the CPU on the master control board with serial bus interfaces of the memories on the business boards. The invention furthermore discloses a method for realizing the reading and writing of the single-board information. The system and method disclosed by the invention are relatively simple, high in reliability and low in cost.

Description

technical field [0001] The invention belongs to the field of electronic communication, and in particular relates to a system and a method for realizing reading and writing of information on a single board. Background technique [0002] The board information mainly includes the board's electronic label, manufacturing information, and working status records. It is a kind of data stored in the non-volatile memory on the board. The electronic label and manufacturing information are used to record and identify the name of the board. Model, barcode, BOM (Bill of Material, Bill of Materials) code and description, production date, manufacturer, manufacturing location and other key content, can also include software / logic / hardware / structural information on the board, business configuration data, single Board processing / repair records, etc. The working state record is mainly for some abnormal states of the board during the working process, such as reset / crash, and make corresponding ...
