Description

Background Art

[0002] Goldfinger boards are widely used in the field of high-speed signal processing. In particular, the development of artificial intelligence has increased the demand for high speed, and the demand for goldfinger boards has increased rapidly. During the plug-in and unplug process, the goldfinger board will rub the contacts, and repeated friction may cause wear on the goldfinger. Worn goldfinger contacts will cause abnormal transmission signals, so goldfinger boards need to be scrapped after a certain number of plug-ins and unplugs. Therefore, it is very important to accurately record the number of plug-ins and unplugs.

[0003] Currently, there are two main ways to record the number of gold finger plug-ins and pull-outs: 1 is mechanical, using a device to continuously plug and unplug the gold finger, and the plug and unplug device records the number of times; generally, the board is not powered on; 2 is to use the monitoring pin of the gold finger itself to record. The gold finger board needs to be powered on.

[0021] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0022] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0023] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0024] To facilitate understanding of the detection system and method for the number of plug-in and unplugging times of the gold finger circuit board provided in the embodiment of the present application, its application scenario is first explained. The detection system and method for the number of plug-in and unplugging times of the gold finger circuit board provided in the embodiment of the present application are used to improve the accuracy of recording the number of plug-in and unplugging times of the gold finger circuit board, and the cost is low. Gold finger boards are widely used in the field of high-speed signal processing, especially the development of artificial intelligence has an increasing demand for high speed, and the demand for gold finger boards has increased rapidly. During the plug-in and unplugging process, the gold finger board will rub the contacts, and multiple frictions may cause wear to the gold finger. Worn gold finger contacts will cause abnormal transmission signals, so the gold finger board needs to be scrapped after a certain number of plug-ins and unplugs. Therefore, how to accurately record the number of plug-in and unplugging times is very important. At present, there are two main ways to record the number of plug-in and unplugging times of the gold finger: 1 is mechanical, using equipment to continuously plug and unplug the gold finger, and the plug-in and unplugging equipment records the number; generally, the board is not powered on; 2 is to use the monitoring pin of the gold finger itself to record. The gold finger board needs to be powered on. Method 1 is mainly to test the reliability of the gold finger, which requires continuous plugging and unplugging several times in a short period of time. This method is not suitable for use in the process of debugging board functions. The debugging process takes a long time and occupies too much equipment; Method 2 is mainly used for detection during function debugging and cannot monitor power outages. Therefore, a method is needed that can monitor both power-off and power-on conditions and record all plug-in and unplug times. For this purpose, the embodiment of the present application provides a detection system and method for the plug-in and unplug times of a gold finger circuit board, so as to improve the accuracy of recording the plug-in and unplug times of a gold finger circuit board, and the cost is low. The following is a detailed description of the embodiments in conjunction with specific drawings.

[0032] In a specific embodiment, the adjustment mechanism comprises a bendable structure, wherein: One end of the bendable structure is connected to the clamp body, and the other end is connected to the signal transmitting unit or the signal receiving unit.

[0033] In a specific implementation manner, the signal transmitting unit is a photoelectric transmitter, and the signal receiving unit is a photoelectric receiver.

[0034] In a specific possible implementation manner, the display control device is integrated into one piece.

[0035] In a specific implementation manner, a spring 8 is provided on the caliper body.

[0036] Specifically, the detection system of the number of plug-in and pull-out times of the gold finger circuit board is described as follows: refer to Figure 3, after the gold finger circuit board 9 is inserted into the slot 10, there will be a gap 11. Let H be the length of the gold finger groove, and L be the depth of the gold finger insertion; after insertion, the height of the groove gap is HL. When the gold finger is inserted, the gold finger groove will be blocked by the slot until it is fully inserted, leaving a gap. Because the gold finger itself and the slot are opaque, the characteristics of the photoelectric transceiver are used to monitor the plugging and unplugging process here, and perform plugging and unplugging monitoring.

[0037] refer to Figure 1 When there is no object blocking the light, the receiving diode can receive the light signal from the transmitting end and can generate a low level to the control unit; when there is an object blocking the light, the receiving diode cannot receive the light signal from the transmitting end and can generate a high level to the control unit.

[0038] refer to Figure 2 , the display control device comprises: Switch, used to control the opening and closing of the device; Three buttons are used to set the parameters of the device, including test, zeroing, and target value.

Display screen, used to display the number of plugging and unplugging times; Indicator light, used to indicate the status of the device: including: When plugged in, the red light is on; when unplugged, the green light is on; when the target number is exceeded, the red and green lights are on at the same time; Also includes internal batteries, wires, and circuit boards.

[0039] The working process of the detection system of the number of plug-in and pull-out times of the gold finger circuit board is as follows: Clamp the device on the edge of the gold finger board, place the photoelectric transmitting and receiving diodes on both sides of the gold finger board, and place the transmitting and receiving diodes opposite to each other, slightly below the HL above the groove, and the green light will be on; Set the target number of times, such as 500; that is, when the number of plugging and unplugging exceeds 500, the buzzer alarms and the red and green lights are on at the same time; when the target number of times is reached, press the reset key to recount; the test key can be used to test whether the position and function of the transceiver diode are correct; for example, if an obstacle is blocked between the receiving and transmitting, will there be any reaction; after the test, press the reset key to reset. After inserting the gold finger board into the slot, the red light is on, generating a high level to the microcontroller, the microcontroller counts +1, and records it in the memory. This cycle repeats. For the problem of monitoring the number of plugging and unplugging of the gold finger, both the power-off and the non-power-off situations can be monitored, and the total number of times can be accurately recorded. Moreover, compared with the use of special equipment, the price is cheap.
