Device, method and system for identifying slot position address and type of communication device board card

Abstract

A device for identifying the slot position address and the type of a communication device board card is provided with a control unit, and further comprises a type unit which is used for being connected with the board card to receive a type signal sent by the board card; a slot position unit used for being connected with detection contacts of all slot positions in the board card to obtain address signals corresponding to the slot positions; an identification unit comprising a single-board CPU and being used for being connected with the output ends of the type unit and the slot position unit andidentifying the board card type and the board card address after receiving a corresponding type signal and an address signal; and an switching unit, the input end of the switching unit being connected with the control unit, and the output end of the switching unit being connected with the type unit and the slot position unit respectively and can be controlled by the control unit to switch the connection objects of the identification unit. The identification unit is connected with the slot position unit, and the identification unit identifies the address of the correspondingly connected boardcard according to the address signal. And the identification unit is connected with the type unit and identifies the type of the correspondingly connected board card according to the type signal.

Description

technical field [0001] The invention relates to a circuit and method for slot identification and disc type identification of hardware boards in a wave division electric cross transmission equipment system, and belongs to the field of identification communication equipment. Background technique [0002] With the development of the communication industry, the demand for large-capacity broadband networks is increasing, and the development and research of high-density, high-speed optical fiber transmission systems are becoming more and more urgent. The balance of performance and power consumption has gradually become the mainstream equipment form of optical communication transmission. The ATCA (Advanced Telecom Computing Architecture) standard is an advanced telecom computing platform. At present, communication equipment manufacturers generally adopt the ATCA standard, meet the requirements of an open standard hardware architecture platform, and provide high-density and high-per...

Problems solved by technology

This type of dial-up unit is composed of some switch circuits. It needs to be set through manual dial-up process before being deployed on the single board. The disadvantage is that it will occupy a certain layout area and hardware IO resources, and the flexibility and scalability are both Not good, for example, the design only needs to meet 2 types of identification at the beginning, but with the development of business, it is powerless to implement 4 types of identification, and hardware changes are required to realize it

[0006] The second idea is the combination of software and hardware, using the existing IO plug-in logic circuit similar to the 38 decoder to realize, the output logic is controlled by the simple input logic, and more identification types are expanded by realizing the amplification of the address Quantity, the disadvantage is that it will depend on the implementation of the software, and it is necessary to design specific logic in the early stage of software initialization, which is not applicable in some scenarios where the initialization software has not yet run

[0007] To sum up, the current board slot identification and board type identification generally belong to two different functional modules, which are realized by two sets of independent hardware circuits, and the design of software and hardware is relatively separated. The overall board occupies more layout space and input and output port resources, which is not economical when considering the cost factors of large-scale production
