Embodiment Construction

[0032] In the present invention, for having (2 n -1) In the system design of one functional single board, n output IO pins are used on each functional single board to indicate the type and number of the single board. These n IO signals can be realized (2 n -1) Mutual identification and wrong insertion detection function of a single board. If the n IOs are all high level, it means that no board is inserted, and the rest (2 n -1) states respectively correspond to the (2 n -1) single board.

[0033] The present invention uses pull-up / pull-down resistors to ensure that all board type IO signal states inserted into the single board output are fixed. After the board is inserted, there will be corresponding signal state changes.

[0034] The principle block diagram of the veneer type identification and detection system proposed by the present invention is shown in FIG. 1 .

[0035] The present invention mainly includes a board type signal generation unit 101 and a detection uni...

Abstract

The invention discloses a method and system of identifying and detecting type of veneer, said system includes board type signal generating unit and detecting unit on function veneer; detecting unit which includes stabilization module, reading module, judging module and output module; function veneer generates veneer type signal; detecting unit reads board type signal state output by all function veneer; detecting unit judges whether the relationship between all function veneer type and slot is correct based on set list of relationship between all function veneer type and slot. If it is correct, continue executing. When the judging module judges the inserting of veneer is fault, result of judgment is output by output module. Hardware of the invention is easy, cost is low, and it can be used as a function sub-module of controlling veneer; user can determine relationship between veneer type and slot, application mode can be agile and changeable; position of fault and type of veneer can be positioned correctly when there is a fault inserting.

Description

technical field [0001] The invention relates to the field of detection in electronic and communication systems, specifically, a system design method and system for board type detection and board type identification for all functional single boards in a distributed system. Background technique [0002] In electronic and communication systems, the distributed control system is usually used to realize the control and monitoring of each functional single board in the system. For example, in large-scale communication equipment, there are often multiple functional single boards in the same chassis. Since they are all in the same chassis, the power and ground interface pins of all functional boards on the chassis backplane sockets are uniformly regulated and allocated to prevent hardware damage caused by wrong board insertion. At the same time, in the same layer of the machine frame, there is a main control single board for realizing the monitoring of all functional single boards....
