For example, the test device 1 is a computer. The test device 1 includes a test system 10 of the fan control board, at least one communication interface 11, a processor 12, and a memory 13. The fan control panel 2 is used to control the fan group 3 to rotate at a predetermined speed. The fan control panel 2 includes at least one communication interface 21. The test device 1 communicates between the test device 1 and the fan control board 2 via the connection of the communication interface 11 and the communication interface 21. In the present embodiment, the number of the communication interface 11 and the communication interface 21 is the same, for example, four. The communication interfaces 11 and 21 are both SMB (System Management Bus) interfaces.

The processor 12 is used to control the operation of the test device 1. The memory 13 is configured to store various IPMI (Intelligent Platform Management Interface) commands generated by the server in all different operating environments and a fan speed range corresponding to each IPMI command. The IPMI command is a command indicating that the temperature of the test device 1 is high, a command indicating that the temperature of the test device 1 is low, or a command indicating that the temperature of the test device 1 is moderate. The timer 14 is used for timing.

Referring to FIG. 2, it is a functional module diagram of the test system of the fan control board of FIG. The test system 10 of the fan control board includes a test request receiving module 110, an IPMI command acquisition module 120, an IPMI command sending module 130, a fan speed receiving module 140, a determining module 150, and a test result output module 160.

The fan control board 2 determines the current operating environment of the testing device 1 in response to the IPMI command from the testing device 1 to control the rotational speed of the fan group 3. For example, the fan control board 2 receives an IPMI command indicating that the temperature of the testing device 1 is high and increases the fan group. The rotational speed of 3 reduces the temperature of the test device 1. At the same time, the fan control board 2 sends a command for the speed of the fan unit 3 to the test device 1 via the communication interface 21, for example, the rotational speed of the fan unit 3 is increased to 80 rpm.

The fan speed receiving module 140 is configured to receive the speed command of the fan group 3 controlled by the fan control board 2 from the fan control board 2 each time. The determining module 150 is configured to determine, according to the rotational speed command, whether the rotational speed of the fan group 3 belongs to the stored fan rotational speed range corresponding to the stored IPMI command.

When the judging module 150 determines the judgment result corresponding to all the IPMI commands, the test result output module 160 is configured to output the test result of the fan control panel according to all the judgment results, specifically: when the judging module 150 obtains all the differences When the rotation speed of the fan group 3 corresponding to the IPMI command belongs to the judgment result of the stored fan speed range corresponding to the IPMI command, the test result output module 160 outputs a test result that the fan control board 2 is successfully tested; When the rotation speed of the fan group 3 corresponding to an IPMI command in all the different IPMI commands does not belong to the determination result of the stored fan speed range corresponding to the IPMI command, the test result output module 160 outputs a test result that the fan control board 2 fails the test. .

Therefore, the test system 10 of the fan control board of the present invention is used in a test apparatus 1 that stores various different IPMI commands generated by the server in all different operating environments and a fan speed range corresponding to each IPMI command. The test system 10 acquires an IPMI command every predetermined period by using an IPMI command of an analogous plurality of servers, and acquires all the different IPMI commands in a predetermined period of time to obtain the fan control board 2 to control the fan group 3. The rotation speed command obtains the judgment result of each time, and outputs the test result to the fan control panel according to all the judgment results, thereby realizing the test of the fan control panel 2, instead of the trouble of testing the fan control panel 2 by using a plurality of servers.

Referring to Figure 3, there is shown a flow chart of a preferred embodiment of the test method for the fan control board of the present invention.

In step S300, the testing device 1 stores various different IPMI commands generated by the server in all different operating environments and a fan speed range corresponding to each IPMI command.

In step S310, the test request receiving module 110 immediately receives the test request from the fan control board 2 through the communication interface 11 and starts testing the fan control board 2.

Step S320, the IPMI instruction acquisition module 120 acquires an IPMI command from the memory 13 every predetermined period and acquires all the different IPMI commands within a preset time period.
