Problems solved by technology

The disadvantages of this approach are:
[0010] 1) The special identification of cables is inspected and confirmed by people, and it cannot be guaranteed to be 100% correct
[0011] 2) The cable coding cannot be normalized, and the risk of availability increases
[0012] 3) If there are more than three miniSAS cables in the design, the cable expandability is not good

Embodiment Construction

[0063] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0064] In the embodiment of the present invention, the detection signal is received through the cable; the first duty ratio is compared with the second duty ratio, or the first frequency is compared with the second frequency, wherein the first duty ratio is the pre-stored The original duty cycle of the detection signal, the first frequency is the original frequency of the detection signal stored in advance, and the second duty cycle is the actual duty cycle of the detection signal after it is transmitted through the cable , the second frequency is the actual frequency after the detection signal is transmitted through the cable; according to the comparison result and a preset line insertion judgment principle, determine the insertion status of the cable. In this way, it is possible to automatically and correctly detect ...

Abstract

The invention relates to a detection method and apparatus of cable plugging case, which comprises the following steps: receiving detection signals by cables; comparing a first duty ratio and a second duty ratio, or a first frequency and a second frequency, wherein, the first duty ratio is an original duty ratio of the detection signal which is prestored, and the first frequency is an original frequency of the detection signal which is prestored, and the second duty ratio is a real duty ratio of the detection signal after cable transmission, and the second frequency is a real frequency of the detection signal after cable transmission; according to the comparison result and the preset cable plugging principle, determining the plugging state of the cable. Thereby, the invention realizes automatic detection of cable plugging state, and is used for automatic detection, so the cables are not needed to be identified by hand operations.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for detecting cable insertion conditions. Background technique [0002] In server products, the connection between the single boards in the rack server is through soft cable connection to realize data interaction. Therefore, there are many cables, and it is easy to have stable plugging but wrong plugging, or unstable plugging. The problem. [0003] Many interfaces with the same function, such as Serial Attached SCSI (Small Computer System Interface), SAS) or Serial Advanced Technology Attachment (Serial Advanced Technology Attachment, SATA) have small SAS interfaces commonly used in the industry (Mini Serial Attached SCSI, miniSAS) connectors and general-purpose miniSAS cables run in parallel for a long period of time in the chassis. After the cables are crossed many times, it is difficult to distinguish the corresponding relationship with the opposite port. Dur...
