If the specific posture changes, the directional indications will also change accordingly.

[0044] In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0045] Refer to Figure 1 , Figure 1 This is a schematic diagram of the functional structure of the GPU power supply harness detection board related to the embodiment solution of the present utility model.

[0046] As Figure 1 shown, the GPU power supply harness detection board in the embodiment of the present utility model includes: a main controller 3 and a GPU power supply harness connection port 12.

[0047] Among them, the number of GPU power supply harness connection ports 12 is at least two, and its specific number can be selected according to the actual application situation, such as 4, 2, 5, 6, etc., and the embodiments of the present application do not limit this.

[0048] It should be noted that one end of the GPU power supply harness connection port 12 is connected to the output control end of the main controller 3, and the other end is electrically connected to the input detection end of the main controller 3.

[0049] It can be understood that the above GPU power supply harness is a group of cables and interfaces for supplying power to the GPU. Through the GPU power supply harness, the GPU can obtain appropriate, stable and pure voltage and current, thereby ensuring the stability of the GPU performance. By collecting the harness data of the GPU power supply harness through the interface of the GPU power supply harness, and then sending the harness data to the main controller through the input detection end for input detection, the corresponding relationship between the input and output ends of the GPU power supply harness can be quickly determined, and the definition of the GPU power supply interface can be confirmed. At the same time, the current and power consumption of the GPU board during operation can also be determined through current monitoring.

[0050] It should be understood that the above output control end can be an interface for the GPU power supply harness to input harness data into the main controller to achieve system control, and the above input detection end is also an interface for input detection of the harness data of the GPU power supply harness.

[0051] It should be explained that by connecting through the GPU power supply harness connection port 12 with the GPU power supply harness, the harness data of the GPU power supply harness can be collected. The harness data can at least include the level signal of the GPU power supply harness.

[0052] In the embodiments of the present application, the main control chip processes the GPIO port level signal collected from the GPU power supply harness connection port 12. When the read level signals are all consistent with the target level, it can be explained that the wire sequence of the GPU power supply harness is correct, and the corresponding GPU power supply harness detection result is output.

[0053] It should be understood that the above target level can be a low level or a high level, and the embodiments of the present application do not limit this.

[0054] It should be noted that the output manner of the above GPU power supply harness detection result can be output to the host computer, display screen, LED lamp 7, etc. in the form of different voltage values or level signals, and the embodiments of the present application do not limit this.

[0055] It can be understood that under the correct wire sequence configuration, each wire position of the GPU power supply harness should be connected to the GPIO port (GPU power supply harness connection port 12) according to the preset connection method. When all wire positions are correctly connected, by reading the GPIO port data, it can be determined that all wire positions are correctly connected, that is, the wire sequence of the GPU is correct.

[0056] It should be understood that when the level signals read are not all the target levels, it indicates that the wire sequence is incorrect.

[0057] Specifically, the GPU power supply harness connection port 12 is used to collect the harness data of the GPU power supply harness and transmit the harness data to the main controller 3; the harness data at least includes: level signals;

[0058] The main controller 3 is used to determine that the GPU power supply harness detection result is correct in wire sequence when the level signals collected by each GPU power supply harness connection port 12 are all consistent with the target level;

[0059] The main controller 3 is further used to determine that the GPU power supply harness detection result is incorrect in wire sequence when there is a level signal collected by the GPU power supply harness connection port 12 that is inconsistent with the target level.

[0060] It should be noted that the above GPU power supply harness detection result can be in the form of a level or a voltage, and the embodiments of the present application do not limit this. For example, when the wire sequence is correct, a high level can be output as the GPU power supply harness detection result, and conversely, a low level can be output as the GPU power supply harness detection result; another example is that when the wire sequence is correct, a 3V voltage is output as the GPU power supply harness detection result, and conversely, a 5V voltage is output as the GPU power supply harness detection result.

[0061] In an implementation manner of the embodiments of the present application, in order to display the GPU power supply harness detection result, a screen connector can also be provided on the GPU power supply harness detection board, and through this screen connector, the main controller 3 can be connected to an external screen.

[0062] It should be noted that when the main controller 3 is connected to an external screen, the main controller 3 can send the GPU power supply harness detection result to the external screen for display.

[0063] It can be understood that when the level signals collected by each GPU power supply harness connection port 12 are all the target levels, the main controller 3 can send the level signal or voltage signal corresponding to the target level signal to the external screen. When the external screen receives the level signal or voltage signal, it can be displayed, so that the user can determine whether the GPU power supply harness detection result is correct in wire sequence or incorrect in wire sequence.

[0064] In an implementation manner of the embodiment of the present application, in order to display the detection result of the GPU power supply harness, a display module may also be provided on the GPU power supply harness detection board. The display module may be equipped with a display screen, and the main controller 3 may send the GPU power supply harness result to the display screen for visual display. The sending method of the GPU power supply harness result may be the same as the method of sending to an external screen as described above, and the embodiments of the present application will not elaborate on this.

[0065] It should be noted that the harness data in the embodiments of the present application may also include current data and voltage data.

[0066] In an implementation manner of the embodiment of the present application, according to the current data and voltage data, power data can also be easily obtained. Therefore, the above-mentioned harness data may also include power data.

[0067] In an implementation manner of the embodiment of the present application, the above-mentioned current data, voltage data, and power data may also be sent to the display module for visual display.

[0068] In an implementation manner of the embodiment of the present application, an LED lamp may also be provided on the detection board. The number of the LED lamps may be one or two, and the embodiments of the present application do not limit this.

[0069] It should be noted that when the number of the LED lamps is one, the LED lamp can light up according to different signals sent by the main controller 3, so that the user can determine different GPU power supply harness detection results. For example, when a high-level signal is input, the LED lamp lights up green, and when a low-level signal is input, the LED lamp lights up red; another example is that when a high-level signal is input, the LED lamp lights up continuously, and when a low-level signal is input, the LED lamp flashes. The embodiments of the present application do not limit the lighting method of the LED lamp, and can be selected according to the application in the actual situation.

[0070] It can be understood that when the number of the LED lamps 7 is two, the first LED lamp 7 and the second LED lamp 7 are both connected to the main controller 3. When the main controller 3 receives the level signals collected by each GPU power supply harness connection port 12, it judges these level signals. When they are all consistent with the target level, the first LED lamp 7 is turned on, so that the user can determine that the GPU power supply harness detection result is correct in wire sequence; when there is a level signal inconsistent with the target level, the second LED lamp 7 is turned on, so that the user can determine that the GPU power supply harness detection result is incorrect in wire sequence. That is, the detection board further includes: a first LED lamp 7 and a second LED lamp 7;

[0071] The first LED lamp 7 and the second LED lamp 7 are both connected to the main controller 3;

[0072] The main controller 3 is further configured to turn on the first LED lamp 7 when the level signals collected at each of the GPU power supply harness connection ports 12 are all consistent with the target level;

[0073] The main controller 3 is further configured to turn on the second LED lamp 7 when there is a signal among the level signals collected at each of the GPU power supply harness connection ports 12 that is inconsistent with the target level.

[0074] The GPU power supply harness detection board according to the embodiment of the present application includes: a main controller 3 and at least two GPU power supply harness connection ports 12; wherein, one end of the GPU power supply harness connection port 12 is connected to the output control end of the main controller 3, and the other end is connected to the input detection end of the main controller 3; the GPU power supply harness connection port 12 is configured to collect the harness data of the GPU power supply harness and transmit the harness data to the main controller 3; the harness data at least includes: a level signal; the main controller 3 is configured to determine that the line sequence of the GPU power supply harness is correct when the level signals collected at each of the GPU power supply harness connection ports 12 are all consistent with the target level; the main controller 3 is further configured to determine that the line sequence of the GPU power supply harness is incorrect when there is a signal among the level signals collected at the GPU power supply harness connection port 12 that is inconsistent with the target level. Since the input detection end of the main controller 3 is connected through the GPU power supply harness connection port 12, the line sequence measurement of the GPU harness is realized, and it is not necessary to measure pin by pin, which improves the efficiency of GPU power supply harness detection. At the same time, the solution of the present application can also perform current and voltage detection, so as to realize the monitoring of the current and power consumption when the GPU board is working.
