In one possible implementation, in conjunction with fig. 4, the dwell test method may include: when the performance to be tested comprises a pressure maintaining test, the target performance testing unit comprises a pressure maintaining unit, and the standard data comprises a target pressure maintaining pressure and a preset first pressure threshold;
then, sequentially calling target performance test units corresponding to the to-be-tested performance based on a test sequence according to the standard data of the test environment and the actual data of the test environment to perform a test, including a 1-A3:
a1, when the first actual pressure of a target air source to be filled into the liquid cooling equipment to be tested is not lower than the target pressure maintaining pressure of the liquid cooling equipment to be tested, controlling the first ball valve to be opened at a preset opening and closing degree, and controlling the first electromagnetic valve to be opened; the first ball valve and the first electromagnetic valve are both arranged on an inflation pipeline for transmitting the target gas source to the liquid cooling equipment to be tested;
it should be noted that, in this embodiment, the execution main body may be a control unit, and the manner of acquiring the standard data may be that after the standard data is input by the user, the controller acquires the standard data, or may acquire the standard data by way of network reception. Standard data of the pressure holding test of the device to be tested, for example, pressure holding information required when performing the pressure holding test, may be preset, where the pressure holding information at least includes a target pressure and a pressure holding duration. When the pressure maintaining test is performed, the standard data of the to-be-tested device to be tested can be directly obtained, and further, when the pressure maintaining capability of the to-be-tested device is tested by introducing gas into the to-be-tested device, the first actual pressure of the target gas source to be filled into the to-be-tested device can be monitored, the first actual pressure can be obtained by detecting the actual pressure of the target gas source through the first pressure detection device, the detected first actual pressure is transmitted to the control unit, and real-time calculation can be performed by obtaining state parameters of each device of the system, such as gas flow rate, pipeline volume and the like, for example, the example is not limited. The target pressure maintaining pressure is a pressure value required to be maintained in the liquid cooling device to be tested in the pressure maintaining test, and the pressure maintaining time is the time length of the target pressure maintaining pressure required to be maintained by the device to be tested in the pressure maintaining test.
It should be noted that, after the first actual pressure and the target holding pressure are obtained, it is necessary to determine whether the pressure of the target gas source meets the requirement, that is, whether the first actual pressure is not lower than the target holding pressure, and when the first pressure is not lower than the target holding pressure, it indicates that the pressure of the target gas source at this time meets the requirement, and then the device to be tested may be inflated, and if the target gas source is used as a provider of the gas source, if the pressure does not meet the requirement, the device to be tested may not be inflated. Specifically, when the first actual pressure of a target gas source to be filled into the equipment to be tested is not lower than the target pressure maintaining pressure of the equipment to be tested, the first ball valve is controlled to be opened at a preset opening and closing degree, and the first electromagnetic valve is controlled to be opened; the first ball valve and the first electromagnetic valve are both arranged on an air inflation pipeline for transmitting a target air source to the equipment to be tested.
It can be understood that, in this embodiment, no matter which valve is in the closed state when the pressure holding test is not started, and after the pressure holding test is started, the valve is controlled to be opened or closed according to different test stages according to requirements, wherein the first ball valve and the first electromagnetic valve are both installed on an inflation pipeline for transmitting a target gas source to a device to be tested, and are used for controlling a flow state of the target gas source on the inflation pipeline, so that when a first actual pressure is not lower than a target pressure holding pressure, it is indicated that a pressure state of the target gas source reaches the standard, the device to be tested can be inflated, and the first ball valve and the first electromagnetic valve which are in the closed state are opened, so as to fill the target gas source into the device to be tested. In order to ensure the pressure state of the device to be tested, the pressure of the device to be tested is monitored in real time when the device to be tested is filled with the target gas source. The opening and closing degree of the ball valve is used for controlling the flow rate of the target air source so as to control the charging speed of the target air source. In this embodiment, the preset opening/closing degree may be 20%, but may be set correspondingly according to different test requirements, and is not limited herein.
A2, monitoring the real-time second actual pressure of the liquid cooling device to be tested;
a3, when the second actual pressure is equal to a preset first pressure threshold value, controlling the first electromagnetic valve to switch between an opening state and a closing state according to a preset first opening and closing frequency, and controlling the first electromagnetic valve and the first ball valve to be in the closing state until the second actual pressure is equal to a target pressure maintaining pressure, wherein the preset first pressure threshold value is smaller than the target pressure maintaining pressure.
Further, the pressure of the device to be tested in the inflation process is monitored in real time, that is, the real-time second actual pressure of the device to be tested is monitored, which can be specifically realized by the second pressure detection device (P) 3214. In the process of monitoring the second actual pressure of the device to be tested in real time when the target gas source is being filled, the second actual pressure can be compared with a preset first pressure threshold value to determine the current inflation state, wherein the preset first pressure threshold value is smaller than the target pressure maintaining pressure, for example, the target pressure maintaining pressure is 0.6MPa, the preset first pressure threshold value can be 0.55MPa, the real-time inflation transition state can be monitored by setting the preset first pressure threshold value to determine whether the target pressure value is approached, when the second actual pressure is equal to the preset first pressure threshold value, the second actual pressure approaches the target pressure value and the inflation is about to be completed, so when the second actual pressure is equal to the preset first pressure threshold value, the first electromagnetic valve is controlled to switch between the open state and the closed state according to the preset opening and closing frequency until the second actual pressure is equal to the target pressure maintaining pressure, and controlling the first electromagnetic valve and the first ball valve to be in a closed state. Namely, when the inflation is to be completed, the inflation of the target air source is controlled by switching the on-off state of the first electromagnetic valve.
It should be noted that, because the ball valve has a certain delay, when the ball valve controls the charging of the target air source, the pressure in the device to be tested may not be equal to the target holding pressure due to the delay, if the ball valve is turned off when the pressure approaches the target holding pressure in order to avoid the delay, the actual pressure in the device to be tested may be lower than the target holding pressure, if the ball valve is turned off when the pressure is equal to the target holding pressure, the delay may be caused for several seconds, the air source is still being charged, the actual pressure in the device to be tested may be higher than the target holding pressure, and the actual pressure in the device to be tested may not be accurately kept at the target holding pressure. Due to the delay of the ball valve, the constant pressure time is also prolonged in the process of frequent opening and closing, and the efficiency of the pressure holding test is reduced. Therefore, the electromagnetic valve can be immediately switched on and off by configuring one electromagnetic valve, no delay influence exists, specifically, when the air inflation is performed, the first ball valve and the first electromagnetic valve are opened to conduct the air inflation pipeline, so that the target air source can be inflated into the equipment to be tested, and the first ball valve is opened at a preset opening degree to control the flow rate of the target air source. When aerifing and being about to end, switch between open mode and closed condition through the first solenoid valve of predetermined frequency control that opens and shuts, when second actual pressure equals target pressurize pressure, also when aerifing the completion, control first solenoid valve and first ball valve and be in closed condition, can understand because the switch of solenoid valve does not have the delay, consequently, not only can realize the quick invariant of actual pressure in the equipment to be tested at target pressurize pressure when the shutoff, and can also make the improvement invariable precision at target pressurize pressure to actual pressure through frequent on-off solenoid valve.
In a feasible implementation manner, if the standard data further includes a pressure maintaining duration, then obtaining test data detected by a target detection unit corresponding to the target performance test unit, and generating a performance test result according to the obtained test data may include: after the inflation is finished (after the first electromagnetic valve and the first ball valve are controlled to be in a closed state), the pressure maintaining capacity is determined, and the pressure maintaining capacity of the equipment to be tested is determined according to the pressure data and a preset rule by monitoring the pressure data of the equipment to be tested in a pressure maintaining time period in real time. Wherein, the length of pressurize time can set up according to actual demand, does not do the restriction once more. It can be understood that the pressure data in the pressure holding time period can reflect the pressure change of the device to be tested in the pressure holding period, so that the pressure holding capacity can be evaluated, and the pressure holding capacity is used for reflecting the air tightness of the device to be tested. The preset rule is used as a basis for judging the pressure maintaining capacity.
For example, timing can be performed according to the pressure holding time length, the initial pressure of the device to be tested at the starting time of the pressure holding time length and the cut-off pressure of the device to be tested at the cut-off time of the pressure holding time length are obtained, and the difference between the initial pressure and the cut-off pressure is substituted into a preset leak rate algorithm to determine a target leak rate; and determining the pressure maintaining capacity of the liquid cooling equipment to be tested according to the target leakage rate.
Specifically, the preset leak rate algorithm may be: leak rate a 1 ＝(P 1 -P 2 ) Volume/dwell time, wherein P 1 Is an initial pressure, P 2 For stopping pressure, the volume is that of the liquid cooling equipment to be measuredAnd (4) inputting dynamically. The liquid cooling devices to be tested of different device types have different volumes, for example, the volume of a cabinet is larger than that of a server. Determining the pressure maintaining capacity of the liquid cooling equipment to be tested according to the target leakage rate and a preset leakage rate threshold value; the leakage rates of the liquid cooling devices to be tested of different device types are different, wherein if the selection of the devices to be tested is a node (server), the threshold value of the leakage rate is a 0 And if the equipment to be tested is selected to be a cabinet, the leakage rate threshold value is a 0 If the target leakage rate is less than or equal to the target leakage rate threshold value, determining that the pressure maintaining capacity of the equipment to be tested is qualified; and if the target leakage rate is greater than the target leakage rate threshold value, determining that the pressure maintaining capacity of the equipment to be tested is unqualified.
