Problems solved by technology

The existing technology for locating and detecting whether the daughter card is inserted in place usually only detects whether the positioning pin on the daughter card is inserted in place, and does not detect whether the daughter card is connected reliably after insertion and whether it can work in a normal environment. When the device fails, it is difficult to locate and find the plug-in connection problem of the daughter card

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the interface system described in the specific embodiment of the present invention, when the daughter card is inserted into the backplane, in addition to detecting whether the daughter card is correctly installed in place, it further detects the code of the chassis where the daughter card is inserted into the backplane and the code of the inserted slot, Determine whether the current working environment of the subcard is suitable, and ensure that the subcard and the backplane can be reliably connected and run normally.

[0034] figure 1 It is a schematic structural diagram of the interface system described in a specific embodiment of the present invention, see figure 1 , the interface system 10 is arranged on the backplane 20, the interfac...

Abstract

An interface system (10) for ensuring connection reliability between a sub-card and a backboard (20) in rack equipment is provided. The interface system (10) comprises: a board in-place detection unit (11) for detecting whether the sub-card is inserted into place correctly when a connection pin set of the sub-card is inserted into a connector on the backboard (20); a chassis detection unit (12) for judging whether the current chassis inserted into by the sub-card is the applicable chassis for the sub-card; and a slot position detection unit (13) for judging whether the current slot position inserted into by the sub-card is the applicable slot position for the sub-card. When the sub-card is inserted into the backboard (20), the interface system (10) not only detects whether the sub-card is correctly installed into place, but also further detects the code of the chassis with the backboard (20) into which the sub-card is inserted and the code of the slot position being inserted, and confirms the present working environment of the sub-card, thus comprehensively detecting the connection status between the sub-card and the backboard (20), and ensuring the reliable connection between the sub-card and the backboard (20). A backboard (20) and a method for ensuring connection reliability between a sub-card and a backboard (20) in rack equipment are also provided.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to an interface system, a backboard and a method for ensuring the connection reliability between a daughter card and a backplane in a rack-mounted device. Background technique [0002] With the development of communication technology, the functions of communication equipment products are becoming more and more powerful, but the appearance design is becoming more and more exquisite. As a result, the density of components inside communication equipment products is getting higher and higher, and the density of internal backplanes of communication equipment products and The density of connectors on the backplane is also increasing day by day. [0003] Due to the increase in the arrangement density of the backplane and the arrangement density of the connectors on the backplane, it is required that the plugging force between the daughter card and the backplane also needs to be ...
