Problems solved by technology

[0003] Existing rack-mounted devices or other card devices do not have a functional module to identify the plug-in information of sub-cards. Therefore, when one or more sub-cards are inserted and pulled out, the system will not be able to identify and make corresponding processing.

Embodiment Construction

[0016] The present invention is further elaborated below by way of specific embodiments:

[0017] This embodiment provides a board card automatic identification device (such as figure 1 ), the device includes a main card and several sub-cards, the main card and several sub-cards are connected to the bus in parallel, each sub-card includes an identifier, and the main card includes an identification module for automatically identifying the identifier of each sub-card .

[0018] The identifier of the sub-card includes an identification code for specifying the function category of the sub-card. The identifiers of each sub-card include different identification codes. The main card also includes a memory for storing the identification code. The bus is an I2C bus or a CAN bus. The main card and several sub-cards can be hot-swapped and connected to the bus in parallel.

[0019] The identification method of described board card automatic identification device comprises the followi...

Abstract

The invention provides an automatic identification device of a media board. The automatic identification device comprises a main board and a plurality of secondary boards, wherein the main board and the secondary boards are both connected to a bus in parallel, each secondary board comprises an identifier, and the main board comprises an identification module used for automatically identifying each identifier of each secondary board. According to the automatic identification device of the media board, the identification modules are added to the main board, a unique identification code is set for each secondary board, and therefore the main board can process plug and pull information timely and correspondingly when the secondary boards are plugged and pulled.

Description

technical field [0001] The invention relates to a board card automatic identification device, in particular to a board card automatic identification device capable of automatically identifying the insertion and extraction of sub-cards. Background technique [0002] At present, most rack-mounted devices or other board devices use single-chip microcomputer technology and distributed structure systems. It mainly includes main card, sub-card and other components. There are independent single-chip microcomputer modules on the main card and sub-cards, and each sub-card has its own independent functions. Each daughter card adopts modular design, and can be hot-swappable and connected to the bus, the whole system is convenient for expansion and maintenance. [0003] Existing rack-mounted devices or other board devices do not have a functional module for identifying subcard insertion and removal information. Therefore, when one or more subcards are inserted or pulled out, the syste...
