As shown in
In practical applications, specific principles of adopting the fan testing system 100 provided by the present disclosure to test a fan are as follows.
A staff inputs the resistance value of the device, the output voltage value of the power supply, and the default range of the power consumption of the power supply in the practical scenario, and the default operating parameter of the to-be-tested fan into the control apparatus 140 according to the practical application scenario of the to-be-tested fan.
For example, when whether the to-be-tested fan can perform normal heat dissipation on a jacquard machine is tested, a resistance value of the jacquard machine, an output voltage value of a power supply and a default range of power consumption of the power supply under an operating environment of the jacquard machine, and the default operating parameter of the to-be-tested fan are inputted into the control apparatus 140.
For example, when whether the to-be-tested fan can perform normal heat dissipation on a computer is tested, a resistance value of the computer, an output voltage value of a power supply and a default range of power consumption of the power supply under an operating environment of the computer, and the default operating parameter of the to-be-tested fan are inputted into the control apparatus 140.
After the resistance value of the device, the output voltage value of the power supply, the default range of the power consumption of the power supply, and the default operating parameter of the to-be-tested fan are input into the control apparatus 140 by the staff, the control apparatus 140 adjusts the resistance value of the adjustable load apparatus 110 and the output voltage value of the power supply apparatus 130 based on the resistance value of the device and the output voltage value of the power supply respectively, to cause the resistance value of the adjustable load apparatus 110 to be equal to the resistance value of the device, and to cause the output voltage value of the power supply apparatus 130 to be equal to the output voltage value of the power supply.
After finishing adjusting the resistance value of the adjustable load apparatus 110 and the output voltage of the power supply apparatus 130, the control apparatus 140 controls the power supply apparatus 130 to supply power to the adjustable load apparatus 110 and the to-be-tested fan based on the output voltage value of the power supply apparatus 130.
After the power is supplied to the adjustable load apparatus 110 and the to-be-tested fan, the control apparatus 140 performs test on the to-be-tested fan based on the testing item.
Specifically, the control apparatus 140 first tests whether the to-be-tested fan is qualified at the maximum rotational speed. When the control apparatus 140 tests whether the to-be-tested fan is qualified at the maximum rotational speed, the control apparatus 140 adjusts the rotational speed of the to-be-tested fan to the maximum rotational speed, and tests whether the rotational speed of the to-be-tested fan reaches the maximum rotational speed after a preset time interval; and if the rotational speed of the to-be-tested fan reaches the maximum rotational speed, the control apparatus 140 acquires an operating parameter of the to-be-tested fan at the maximum rotational speed and power consumption of the power supply apparatus 130. It can be understood that if the rotational speed of the to-be-tested fan does not reach the maximum rotational speed, the to-be-tested fan is not qualified at the maximum rotational speed. The control apparatus 140 compares the operating parameter of the to-be-tested fan at the maximum rotational speed with the default operating parameter range, and compares the power consumption of the power supply apparatus 130 with the default range of the power consumption of the power supply; and if the operating parameter is within the default working parameter range and the power consumption of the power supply apparatus 130 is within the default range of the power consumption of the power supply, the to-be-tested fan is qualified at the maximum rotational speed.
The control apparatus 140 then tests whether the to-be-tested fan is qualified at the minimum rotational speed. When the control apparatus 140 tests whether the to-be-tested fan is qualified at the minimum rotational speed, the control apparatus 140 adjusts the rotational speed of the to-be-tested fan to the minimum rotational speed and tests whether the rotational speed of the to-be-tested fan reaches the minimum rotational speed after a preset time interval; and if the rotational speed of the to-be-tested fan reaches the minimum rotational speed, the control apparatus 140 acquires an operating parameter of the to-be-tested fan at the minimum rotational speed and power consumption of the power supply apparatus 130. It can be understood that if the rotational speed of the to-be-tested fan does not reach the minimum rotational speed, the to-be-tested fan is not qualified at the minimum rotational speed. The control apparatus 140 compares the operating parameter of the to-be-tested fan at the minimum rotational speed with the default operating parameter range, and compares the power consumption of the power supply apparatus 130 with the default range of the power consumption of the power supply; and if the operating parameter is within the default operating parameter range and the power consumption of the power supply apparatus 130 is within the default range of the power consumption of the power supply, the to-be-tested fan is qualified at the minimum rotational speed.
The control apparatus 140 finally tests whether the to-be-tested fan is qualified when the rotational speed of the to-be-tested fan is adjusted at a certain step speed. When the control apparatus 140 tests whether the to-be-tested fan is qualified when the rotational speed of the to-be-tested fan is adjusted at the certain step speed, the control apparatus 140 adjusts the rotational speed of the to-be-tested fan at the certain step speed, and tests whether the rotational speed of the to-be-tested fan reaches a preset rotational speed after a preset time interval; and if the rotational speed of the to-be-tested fan reaches the preset rotational speed, the control apparatus 140 acquires an operating parameter of the to-be-tested fan at the preset rotational speed and power consumption of the power supply apparatus 130. It can be understood that if the to-be-tested fan does not reach the preset rotational speed, the to-be-tested fan is not qualified at the preset rotational speed. The control apparatus 140 compares the operating parameter of the to-be-tested fan at the preset rotational speed with the default operating parameter range, and compares the power consumption of the power supply apparatus 130 with the default range of the power consumption of the power supply; and if the operating parameter is within the default operating parameter range and the power consumption of the power supply apparatus 130 is within the default range of the power consumption of the power supply, the to-be-tested fan is qualified at the preset rotational speed.
It should be noted that the step speed refers to a rotational speed that needs to be increased each time when a rotational speed of a fan is adjusted from small to large. For example, the step speed being 10% means that the rotational speed of the fan needs to be increased by 10% when the rotational speed of the fan is adjusted each time. It is required to test multiple times whether the to-be-tested fan is qualified when the rotational speed of the to-be-tested fan is adjusted at the certain step speed, and when a test result in each time is qualified, the to-be-tested fan is qualified in the case of adjusting the rotational speed of the to-be-tested fan at this certain step speed. When the rotational speed of the to-be-tested fan is adjusted at the certain step speed, it may be done by gradually adjusting the rotational speed of the to-be-tested fan from the minimum rotational speed to the maximum rotational speed, or by gradually adjusting the rotational speed of the to-be-tested fan from a smaller rotational speed to a larger rotational speed. Preferably, the rotational speed of the to-be-tested fan is adjusted from the minimum rotational speed to the maximum rotational speed.
For example, adjusting the rotational speed of the to-be-tested fan from the minimum rotational speed to the maximum rotational speed at a step speed of 10% requires 10 tests. Each test corresponds to one preset rotational speed. When a test result of the to-be-tested fan is qualified at each preset rotational speed, the to-be-tested fan is qualified in the case of adjusting the rotational speed of the to-be-tested fan at the step speed of 10%.
For example, adjusting the rotational speed of the to-be-tested fan from 40% of the maximum rotational speed to 80% of the maximum rotational speed at a step speed of 20% requires 2 tests. Each test corresponds to one preset rotational speed. When a test result of the to-be-tested fan is qualified at each preset rotational speed, the to-be-tested fan is qualified in the case of adjusting the rotational speed of the to-be-tested fan at the step speed of 20%.
It can be understood that in the above test process, in the case where the operating parameter includes at least two operating parameter, if at least one of the operating parameter is not within a default operating parameter range thereof, the to-be-tested fan is not qualified.
After completing the above testing item, the control apparatus 140 analyzes whether the to-be-tested fan is qualified in the practical application scenario and saves an analysis result.
If the to-be-tested fan is qualified at the maximum rotational speed, at the minimum rotational speed, and when the rotational speed of the to-be-tested fan is adjusted at the certain step speed, then the to-be-tested fan is qualified in the practical application scenario.
It should be noted that in the testing items disclosed in the present disclosure, order in which the control apparatus 140 executes each test item is not limited, and a staff may configure it according to a practical testing requirement. Moreover, the testing items may be configured in the control apparatus 140 according to the practical test requirement, and are not limited to the testing items disclosed in the present disclosure.
In some implementations, before analyzing whether the to-be-tested fan is qualified in the practical application scenario, the control apparatus 140 will also save the test record of the to-be-tested fan, so as to analyze specific reasons why the to-be-tested fan is not qualified when the to-be-tested fan is not qualified in the practical application scenario.
The test record includes the resistance value of the adjustable load, the output voltage value of the power supply apparatus, the operating parameter of the to-be-tested fan at the maximum rotational speed as well as the power consumption of the power supply apparatus 130 acquired by the control apparatus 140, the operating parameter of the to-be-tested fan at the minimum rotational speed as well as the power consumption of the power supply apparatus 130 acquired by the control apparatus 140, and the operating parameter of the to-be-tested fan at the preset rotational speed as well as the power consumption of the power supply apparatus 130 acquired by the control apparatus 140.
In some implementations, the control apparatus 140 binds and saves the test result and the test record of the to-be-tested fan with the identifier in the identification code attached to the to-be-tested fan, in order to achieve traceability of the test result and the test data of the to-be-tested fan after the to-be-tested fans enters the market a malfunction occurs, thereby preventing the fraudulent behavior by the users.
The above are only specific implementations of the present disclosure, but the protection scope of the present invention is not limited to this. Any skilled person familiar with the technical field in the art can easily think of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
