Embodiment 1

[0026] An embodiment of the present invention provides a method for detecting the presence of a board. In this embodiment, the first board and the second board are connected through a connector, and the first board is provided with at least two levels of in-position signal pins, and the at least two levels of in-position signal pins include at least 1 Level 1 in-position signal pins and level 2 in-position signal pins, wherein the length of the 1st level in-position signal pins is shorter than the common signal pins on the first board, and the length of the 2-level in-position signal pins is shorter on the Level 1 signal pin. That is to say, all the pins on the first board are divided into at least three levels according to the length, and the lengths of the pins are from short to long: 2-level in-position signal pins, 1-level in-position signal pins, and ordinary signal pins . Wherein, the level 2 in-position signal pins and the level 1 in-position signal pins are at least ...

Embodiment 2

[0043] exist figure 1 On the basis of the illustrated embodiments, further, this embodiment provides a specific implementation of a method for detecting the presence of a board. Such as Figure 5 As shown, the method provided in this embodiment includes:

[0044] 501. Set at least two levels of in-position signal pins on the first board, and the at least two levels of in-position signal pins include at least level 1 in-position signal pins and level 2 in-position signal pins.

[0045] Wherein, the length of the level 1 on-position signal pin is shorter than the common signal pin on the first board, and the length of the level-2 on-position signal pin is shorter than the level 1 on-position signal pin.

[0046] 502. When it is detected that the second board is in contact with the level-2 in-position signal pin on the first board, the presence detection module acquires the level-2 in-position signal; When the level 1 in-position signal pin contacts, the presence detection mod...

Embodiment 3

[0064] In order to achieve the above image 3 and Figure 5 With the detection method for board presence shown, this embodiment provides a detection device for board presence. Such as Figure 6a As shown, the board in-position detection device provided in this embodiment includes a first board 61, a second board 62 and an in-position detection module 63; wherein, at least two levels of boards are set on the first board 61 In-position signal pins, the at least two levels of in-position signal pins at least include level 1 in-position signal pins 611 and level 2 in-position signal pins 612, wherein the length of the first-level in-position signal pins 611 is shorter than the Referring to the common signal pin 613 on the first board, the length of the second-level in-position signal pin 612 is shorter than the first-level in-position signal pin 611. Wherein, the second board 62 is a board whose presence is detected, and the presence detection module 63 is located in the second...

Abstract

The invention discloses a board in-situ detection method and system, relates to the technical field of communication, and aims to be used for solving the problem that a control system of equipment cannot accurately judge whether a board is in-situ due to lower accuracy and reliability of board in-situ detection. The method provided by the invention comprises the steps as follows: at least two levels of in-situ signal pins are arranged on a first board and at least comprise a first-level signal pin and a second-level signal pin; when the connection of a second board and the second-level signal pin on the first board is in a stable state, an in-situ detection module determines whether the second board or the first board is in situ according to the acquisition condition of a first-level in-situ signal and a second-level in-situ signal; and when the connection of the second board and the second-level in-situ signal pin on the first board is in an unstable state, the in-situ detection module determines whether the second board or the first board is in situ according to the acquisition condition of the first-level in-situ signal. The board in-situ detection method and device are applicable to the technical field of communication and used for achieving the board in-situ detection.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting the presence of boards. Background technique [0002] In the field of communication technology, devices are often required to support board hot-swappable functions. When the system of the device detects that the board is inserted and the logic level of the in-position signal changes from high to low, it is determined that the board is in place, and the corresponding function of the board is loaded; when the system detects that the board is pulled out, the in-position signal When the logic level of the board changes from low to high, it is determined that the board is not in place, and the corresponding function of the board is uninstalled. It can be seen that, during the operation of the communication device, it is very important to detect whether the board is in place. [0003] At present, the following methods are mainly used to detect...
