Description

Technical Field

[0001] This invention relates to the field of server racks, and more specifically, to a one-way valve detection method, electronic device, and storage medium for server racks. Background Technology

[0002] In server racks, backflow in closed-loop fluid inlets is primarily caused by the siphon effect. To address this, a check valve is typically added to the system. The check valve allows fluid to flow in one direction and closes when it flows in the opposite direction, thus preventing backflow. However, the spring in the check valve may creep after prolonged use, weakening its elasticity. This can lead to backflow when the server rack is stationary, potentially causing the server rack to fail.

[0003] The traditional method for testing check valves is to disassemble the check valve and remove the spring for testing to assess whether its performance has degraded. However, this method is time-consuming and labor-intensive, and may cause additional damage to the valve in actual operation, resulting in low efficiency of check valve testing in server racks in related technologies.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0009] Furthermore, the method also includes: in response to the detection result indicating that the check valve needs to be inspected and the creep level is the first creep level, controlling the pump group of the server rack to pump liquid from the pipeline based on a preset cycle, and outputting a first warning signal, wherein the first warning signal is used to prompt maintenance of the check valve; in response to the detection result indicating that the check valve needs to be inspected and the creep level is the second creep level, outputting a second warning signal, wherein the warning intensity of the second warning signal is less than the warning intensity of the first warning signal.

[0010] Furthermore, detecting the total volume of reverse osmosis fluid in the server rack corresponding to the one-way valve during the static state includes: detecting the first liquid level position of the storage tank corresponding to the pipeline in response to the opening duration of the solenoid valve reaching a first preset duration, wherein the storage tank is used to indicate the fluid entering the pipeline; detecting the second liquid level position of the storage tank in response to the opening duration of the solenoid valve reaching a second preset duration; and determining the total volume of reverse osmosis fluid based on the first liquid level position and the second liquid level position.

[0011] Furthermore, detecting the total volume of reverse osmosis fluid in the one-way valve corresponding to the server rack during the static state includes: determining the total volume of reverse osmosis fluid based on the readings of a first flow meter and a second flow meter, wherein the first flow meter reading represents the flow meter reading obtained at the beginning of the static state, and the second flow meter reading represents the flow meter reading obtained at a preset time point of the static state, and the flow meters are installed between the server rack and the pipe.

It is noteworthy that this application, by first discharging the fluid from the corresponding pipe of the server rack and then detecting the total volume of backflow fluid in the corresponding check valve of the server rack, avoids interference from the original fluid that may exist during the detection process, ensuring that the detected total volume of backflow fluid accurately reflects the creep state of the check valve, thereby achieving the technical effect of accurate detection of the check valve in the server rack, and thus solving the technical problem of low detection efficiency of the check valve in the related art.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] According to an embodiment of the present invention, an embodiment of a one-way valve detection method for a server rack is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0025] Figure 1 This is a flowchart of a one-way valve detection method for a server rack according to an embodiment of the present invention, as shown below. Figure 1 As shown, the method includes the following steps:

[0026] Step S102: In response to the detection of a shutdown command for the server rack, the solenoid valve of the server rack is opened to discharge the fluid in the corresponding pipe of the server rack and the discharge result is obtained, wherein the discharge result is used to indicate whether the fluid has been emptied.

[0027] The aforementioned server rack can refer to a frame containing equipment such as servers, switches, and routers. In addition, a server rack may also contain power supply equipment consisting of one or more battery clusters. These battery clusters can serve as emergency power for the equipment within the server rack, providing continuous power in the event of a mains power failure or outage, ensuring that critical data and operations are not damaged due to power interruption. The battery clusters in the server rack can also function as energy storage and regulation units, used to balance grid load, provide peak power support, or participate in demand response plans. In other words, the aforementioned server rack types may include, but are not limited to, server racks and battery clusters. The specific server rack type needs to be determined based on the actual testing object and is not limited here.

[0028] The aforementioned shutdown command can refer to an instruction used to instruct the server rack to stop its current operating state and enter a static or maintenance mode. The shutdown command can be issued by, but is not limited to, the server rack or battery cluster control system or by an external operator. The specific issuance method needs to be determined based on actual needs and system design, and is not limited here. The triggering reasons for the shutdown command can include, but are not limited to, the need for regular system maintenance, server rack overheating, power supply interruption, or manual operation by the operator. The specific triggering reasons need to be set according to actual needs, and are not limited here. The function of the shutdown command can include, but is not limited to, ensuring the safe and orderly cessation of server rack operation, preventing equipment damage or safety risks caused by accidental operation. The aforementioned solenoid valve can refer to a valve that uses electromagnetic force to control fluid flow. The function of the solenoid valve can include, but is not limited to, precisely controlling fluid flow and controlling the fluid volume in the corresponding pipes of the server rack.

[0029] The fluids mentioned above can refer to substances flowing in the server rack management system. The types of fluids can include, but are not limited to, gases and liquids such as coolants. The specific type of fluid needs to be determined according to the actual system requirements and is not limited here. The function of the fluids can include, but is not limited to, keeping the server racks operating within a suitable temperature range to improve server rack efficiency and extend server rack life.

[0030] In one optional embodiment, when the server rack receives a shutdown command, the solenoid valve is activated to drain the coolant or other fluids from the corresponding pipes in the server rack, and the draining result is obtained. This process, controlled by the shutdown command, prevents potential corrosion or pressure damage to system components from fluids during server rack inactivity or maintenance. Simultaneously, the draining result confirms whether the fluid has been completely drained from the pipes, thus determining whether the server rack can enter inactivity or maintenance mode. If the draining result indicates that the pipes are not emptied, further diagnosis and handling are required to ensure the safety and functional integrity of the server rack.

[0031] In step S104, in response to the discharge result being fluid evacuation, the solenoid valve is closed to allow the server rack to enter a stationary state, where the stationary state indicates that the server rack has stopped working.

[0032] The control methods mentioned above may include, but are not limited to, the following:

[0033] The first method is microprocessor control. The central controller or microprocessor receives signals from the sensors and, after confirming that the fluid has been drained, sends a power-off signal to the coil of the solenoid valve, causing the valve core to close under the action of the spring force.

[0034] The second method involves programmable logic controller (PLC) control, which uses preset control logic to respond to the fluid evacuation result and control the solenoid valve to open or close.

[0035] The third method is relay control. When the system detects a signal that the fluid has been drained, the power supply to the solenoid valve is disconnected via the relay, thereby closing the solenoid valve.

[0036] The above control methods are for illustrative purposes only. The specific control methods should be determined based on the system design and actual needs, and are not limited here.

[0037] The aforementioned static state refers to an operating mode in which the server rack is no longer charging, discharging, or performing any other operations. The benefits of static state may include, but are not limited to, safe shutdown, inspection and maintenance, extending service life, and energy saving.

[0038] In one optional embodiment, in response to confirmation of fluid evacuation, the server rack control system automatically closes the solenoid valve, halting all work and operation activities and entering a static state. This process ensures that during periods when the server rack is not in operation, all potential safety hazards such as pressure buildup, leakage, or corrosion caused by fluid presence are eliminated, significantly improving the overall safety of the server rack. Secondly, periodically suspending the server rack provides maintenance personnel with a safe and stable environment for necessary inspections and maintenance, improving maintenance efficiency and avoiding additional damage and time wasted due to valve disassembly.

[0039] Step S106: Detect the total volume of backflow fluid of the one-way valve corresponding to the server rack during the static state, wherein the one-way valve is installed at a preset position on the pipeline.

[0040] The aforementioned check valve can refer to a control element that allows fluid or gas to flow in only one direction. The types of check valves can include, but are not limited to, spring-loaded check valves, ball check valves, butterfly check valves, etc. The specific type of check valve needs to be determined according to the application scenario and fluid type, and is not limited here. The function of check valves can include, but is not limited to, preventing fluid from flowing back when not in operation and protecting server racks from unnecessary pressure or temperature changes.

[0041] The aforementioned reverse osmosis fluid may refer to fluids that should be blocked by a one-way valve. Reverse osmosis fluid may have a negative impact on the health of the server rack, such as causing the server rack to overheat, corrode, or be damaged by pressure.

[0042] The aforementioned preset position can refer to a specific installation point selected for the check valve during system design. The preset position can include, but is not limited to, any key position on the fluid path. The specific preset position needs to be determined according to the system operation requirements and fluid characteristics. There are no restrictions here. Establishing the preset position helps to optimize the system design, ensure that the check valve can effectively perform its function, and also facilitates subsequent testing and maintenance.

[0043] The detection methods mentioned above may include, but are not limited to, the following:

[0044] The first method involves flow meter detection. By installing a flow meter on the pipeline, the volume of fluid flowing through the check valve during a static state is measured to obtain the total volume of the reverse osmosis fluid.

[0045] The second method involves using a liquid level sensor. By installing a liquid level sensor in the storage tank, the liquid level changes of the server rack before and after entering a static state are recorded, thus obtaining the total volume of the reverse osmosis fluid.

[0046] The above detection methods are for illustrative purposes only. The specific detection methods should be determined based on the system design and fluid type, and are not limited here.

[0047] In one optional embodiment, the total volume of backflow fluid in the one-way valve corresponding to the server rack during the static state is detected. This process is mainly achieved by the one-way valve installed at a preset position on the pipeline, ensuring that the coolant can enter smoothly when the server rack is running and will not flow backward in the static state, thereby effectively preventing coolant backflow caused by spring creep. At the same time, by accurately measuring the total volume of backflow coolant, the system can timely and accurately assess the health status of the one-way valve spring and identify whether the degree of creep has reached a level that affects the safety of the server rack.

[0048] Step S108: The check valve is tested based on the total volume of the reverse osmosis fluid to obtain the test results, which are used to indicate whether the check valve needs to be repaired.

[0049] In one optional embodiment, the total volume of reverse osmosis fluid during the settling period is measured, and then the check valve is inspected based on this volume. The inspection results determine whether the check valve needs maintenance. This inspection process, which uses the total volume of reverse osmosis fluid to determine whether maintenance of the check valve is necessary, can non-destructively and efficiently assess the sealing performance of the check valve and the creep degree of the spring. This allows the system to immediately identify potential performance problems with the check valve and take corresponding measures, effectively improving the system's operating efficiency.

[0050] In this embodiment of the invention, firstly, in response to the detection of a shutdown command from the server rack, the solenoid valve of the server rack is opened to discharge fluid from the corresponding pipe of the server rack and obtain a discharge result; then, in response to the discharge result indicating that the fluid has been emptied, the solenoid valve is closed to allow the server rack to enter a static state; next, the total volume of backflow fluid in the corresponding check valve of the server rack during the static state is detected; finally, the check valve is detected based on the total volume of backflow fluid to obtain a detection result. It is noteworthy that this application, by first discharging the fluid from the corresponding pipe of the server rack and then detecting the total volume of backflow fluid in the corresponding check valve of the server rack, avoids interference from the original fluid that may exist during the detection process, ensuring that the detected total volume of backflow fluid accurately reflects the creep state of the check valve, thereby achieving the technical effect of accurate detection of the check valve in the server rack, and thus solving the technical problem of low detection efficiency of the check valve in the related art.

[0051] Optionally, the check valve is tested based on the total volume of the reverse osmosis fluid to obtain test results, including: determining the creep level of the check valve based on the total volume of the reverse osmosis fluid and a preset volume threshold, wherein the creep level is used to indicate the severity of the performance degradation of the check valve; in response to the creep level being a preset creep level, determining the test result that the check valve needs to be repaired; in response to the creep level being different from the preset creep level, determining the test result that the check valve does not need to be repaired.

[0052] The aforementioned preset volume threshold can refer to one or more reverse osmosis volume thresholds pre-set during the server rack system design phase. These thresholds are used to measure whether the total volume of the reverse osmosis fluid has reached a level that requires attention. The types of preset volume thresholds can include, but are not limited to, the first volume threshold and the second volume threshold. The specific preset volume threshold needs to be determined based on the performance of the check valve and the actual situation. No limitation is made here. The role of the preset volume threshold can include, but is not limited to, serving as a benchmark for judging whether the check valve has performance degradation and creep phenomena.

[0053] The aforementioned preset creep level refers to a pre-set level for classifying and evaluating the creep degree of the check valve. The type of preset creep level may include, but is not limited to, the first creep level and the second creep level. The specific preset creep level needs to be determined based on the performance of the check valve, and is not limited here. The function of the preset creep level may include, but is not limited to, quantifying the health status of the check valve and helping maintenance personnel to take appropriate maintenance strategies.

[0054] In one optional embodiment, the check valve is first tested based on the total volume of the reverse osmosis fluid and a preset volume threshold to determine its creep level. Then, the creep level is compared with a preset creep level to determine whether maintenance is required. This process, by setting preset volume thresholds and creep levels, allows the system to detect potential problems with the check valve early, ensuring system operational safety. Furthermore, it enables different response measures based on the severity of the creep level, effectively balancing maintenance costs and system performance.

[0055] Optionally, the preset volume threshold includes a first volume threshold and a second volume threshold, and the preset creep level includes a first creep level and a second creep level. The creep level of the check valve is determined based on the total volume of the reverse osmosis fluid and the preset volume threshold, wherein the creep level is used to represent the severity of performance degradation of the check valve, including: determining the creep level as a first creep level in response to the total volume of the reverse osmosis fluid being greater than the first volume threshold; determining the creep level as a second creep level in response to the total volume of the reverse osmosis fluid being less than or equal to the first volume threshold and greater than the second volume threshold, wherein the severity of performance degradation of the check valve represented by the second creep level is less than the severity of performance degradation of the check valve represented by the first creep level; and determining the creep level as a non-preset creep level in response to the total volume of the reverse osmosis fluid being less than or equal to the second volume threshold, wherein the second volume threshold is less than the first volume threshold.

[0056] The aforementioned first volume threshold can refer to a pre-set high reverse osmosis fluid volume threshold, representing that the reverse osmosis phenomenon of the check valve in a static state has reached a relatively obvious level, used to indicate the severity of spring creep in the check valve.

[0057] The aforementioned second volume threshold can refer to a pre-set lower reverse osmosis fluid volume threshold, representing that the total volume of reverse osmosis fluid has reached a level that requires attention but has not yet reached a serious level, used to indicate the degree of spring creep of the current check valve that needs attention.

[0058] The aforementioned first creep level can refer to the level of creep of the one-way valve determined by comparing the total volume of the reverse osmosis fluid with the first volume threshold. The first creep level can be used to indicate that the valve's performance has seriously degraded, the spring may have creeped significantly, and the valve needs to be repaired or replaced immediately to prevent coolant backflow from damaging the server rack.

[0059] The aforementioned second creep level can refer to the level of creep degree of the check valve determined based on the comparison between the total volume of reverse osmosis fluid and the first and second volume thresholds. The second creep level indicates that the performance degradation of the check valve is less severe than that indicated by the first creep level. The second creep level can be used to indicate that the performance of the check valve has degraded to a certain extent, but has not yet reached the severity of the first creep level, and maintenance personnel need to pay attention to the performance of this check valve.

[0060] In one optional embodiment, by pre-setting preset volume thresholds, including a first volume threshold and a second volume threshold, and preset creep levels, including a first creep level and a second creep level, the server rack system can determine that the creep level of the one-way valve is the first creep level when the total volume of the backflow fluid exceeds the first volume threshold. This indicates that the valve's performance has significantly degraded and requires emergency repair or replacement to avoid potential safety hazards caused by coolant backflow. When the total volume of the backflow fluid is between the first and second volume thresholds, the system determines that the creep level is the second creep level. This indicates that the valve's performance has slightly degraded but has not yet reached an emergency state. A strategy of regular monitoring and timely maintenance can be adopted to ensure system safety and avoid the cost waste caused by over-maintenance. When the total volume of the backflow fluid is below the second volume threshold, the system determines that the creep level does not belong to the preset creep level, meaning that the one-way valve is working normally and no special intervention is required. The above detection mechanism can not only identify the performance status of the check valve in a timely and accurate manner, but also take graded responses according to different degrees of degradation, thereby optimizing the allocation of maintenance resources. At the same time, it avoids the blind disassembly and testing of check valves in traditional maintenance methods, reduces unnecessary system interruptions and potential damage caused by the testing process, and significantly improves the operational reliability and maintenance efficiency of the server rack system.

[0061] Optionally, the method further includes: in response to the detection result indicating that the one-way valve needs to be inspected and the creep level is a first creep level, controlling the pump group of the server rack to pump liquid from the pipeline based on a preset cycle, and outputting a first warning signal, wherein the first warning signal is used to prompt maintenance of the one-way valve; in response to the detection result indicating that the one-way valve needs to be inspected and the creep level is a second creep level, outputting a second warning signal, wherein the warning intensity of the second warning signal is less than the warning intensity of the first warning signal.

[0062] The aforementioned preset period can refer to a time interval pre-set in the system. The duration of the preset period can include, but is not limited to, one hour, half a day, one day, two days, etc. The specific preset period needs to be determined based on the performance of the one-way valve and the working environment of the server rack. There is no limitation here. The preset period can be used for periodic specific maintenance or testing activities.

[0063] The aforementioned pump unit can refer to an important component of a server rack system, responsible for driving fluid circulation in the pipes to maintain the server rack temperature within a safe range.

[0064] The aforementioned liquid extraction can refer to the extraction of a certain amount of fluid from the pipeline under the control of the pump set, in order to reduce the amount of fluid backflow caused by the creep of the one-way valve.

[0065] The aforementioned first warning signal can refer to the reminder signal issued by the system to maintenance personnel when it detects that the creep level of the check valve is the first creep level. The first warning signal has a high warning intensity, which means that the performance of the check valve has seriously degraded and needs to be repaired or replaced immediately to avoid system failure.

[0066] The aforementioned second warning signal can refer to the reminder signal issued by the system to the maintenance personnel when it detects that the creep level of the check valve is the second creep level. The warning intensity of the second warning signal is less than that of the first warning signal, indicating that although the valve performance has begun to degrade, it has not yet reached an emergency state, reminding the maintenance personnel to arrange the inspection and possible adjustment of the check valve in the subsequent maintenance plan.

[0067] In one optional embodiment, different early warning signals are set for different creep levels—specifically, a first early warning signal is set for the first creep level and a second early warning signal is set for the second creep level. When the check valve is being inspected, the corresponding early warning signal is triggered according to the detected creep level. This avoids overreacting to problems that do not require immediate attention, while ensuring that the maintenance team can still notice early signs of valve degradation, providing guidance for future inspections and maintenance. Through this tiered response mechanism, the system can not only handle urgent issues in a timely manner but also plan ahead for potential maintenance needs, reducing the risk of unplanned downtime, thereby improving the operational efficiency and security of the server rack and reducing maintenance costs.

[0068] Optionally, detecting the total volume of reverse osmosis fluid in the server rack corresponding to the one-way valve during the static state includes: detecting the first liquid level position of the storage tank corresponding to the pipeline in response to the opening duration of the solenoid valve reaching a first preset duration, wherein the storage tank is used to indicate the fluid entering the pipeline; detecting the second liquid level position of the storage tank in response to the opening duration of the solenoid valve reaching a second preset duration; and determining the total volume of reverse osmosis fluid based on the first liquid level position and the second liquid level position.

[0069] The aforementioned first preset duration can refer to the pre-set duration of the solenoid valve's opening. The first preset duration can be set to ten minutes, twenty minutes, thirty minutes, etc. The specific first preset duration needs to be determined based on the fluid volume in the storage tank and the performance of the solenoid valve, and is not limited here. The first preset duration can be used to empty the inlet main pipe to ensure that during the subsequent settling stage, any changes in the liquid level in the storage tank are caused by backflow from the one-way valve, rather than by the influence of the remaining fluid in the pipeline.

[0070] The aforementioned first liquid level position can refer to the liquid level height of the fluid in the storage tank at the end of the first preset time period. This moment is usually the starting point when the system enters a static state after the inlet main pipe is emptied, and the first liquid level position at this time is regarded as the reference point for reverse osmosis detection.

[0071] The aforementioned second preset duration refers to the time required for the system to reopen the solenoid valve after a period of settling in order to measure the change in the liquid level in the storage tank. The second preset duration may include, but is not limited to, ten minutes, twenty minutes, thirty minutes, etc. The specific second preset duration needs to be determined based on factors such as the response speed of the solenoid valve and the accuracy of the measurement system, and is not limited here. The second preset duration can be used to detect the volume change of the reverse osmosis fluid.

[0072] The aforementioned second liquid level position can refer to the liquid level height of the fluid in the storage tank at the end of the second preset time period, which is used to compare with the first liquid level position to calculate the total volume of reverse osmosis fluid.

[0073] In one optional embodiment, by reasonably setting a first preset time, a first liquid level position, a second preset time, and a second liquid level position, the total volume of the reverse osmosis fluid can be determined, thereby determining the degree of creep of the one-way valve. The combined use of the first preset time and the first liquid level position ensures that the fluid in the pipe is completely emptied before the system begins detecting the total volume of the reverse osmosis fluid, avoiding the influence of residual fluid inside the system on the detection results. The determination of the second preset time and the second liquid level position provides important data for assessing the reverse osmosis volume of the one-way valve during the settling period. By comparing the first liquid level position and the second liquid level position, the total volume of the reverse osmosis fluid can be calculated, thereby assessing the degree of creep of the one-way valve. This detection method does not require valve disassembly, which not only reduces maintenance workload but also avoids the additional risks caused by disassembly, improving the detection efficiency of the server rack system.

[0074] Optionally, detecting the total volume of reverse osmosis fluid in the one-way valve corresponding to the server rack during the static state includes: determining the total volume of reverse osmosis fluid based on a first flow meter reading and a second flow meter reading, wherein the first flow meter reading is used to represent the flow meter reading obtained at the beginning time of the static state, and the second flow meter reading is used to represent the flow meter reading obtained at a preset time point of the static state, and the flow meters are installed between the server rack and the pipe.

[0075] In one alternative embodiment, by installing a flow meter between the server rack and the pipe, and using the difference between the first flow meter reading at the start of the stationary state and the second flow meter reading at the end, the total volume of backflow fluid in the check valve can be directly determined. This process can accurately capture the reverse flow of coolant caused by the performance degradation of the check valve during the stationary period, and obtain quantitative data on its creep degree without disassembling the valve, which greatly improves maintenance efficiency and system reliability.

[0076] Optionally, after the solenoid valve of the control server rack is in the open state, the method further includes: in response to the opening duration of the solenoid valve reaching a first preset duration, determining that the discharge result is fluid evacuation.

[0077] In one optional embodiment, by setting a first preset time as a reference standard for emptying the pipeline, it is ensured that there is no undischarged fluid in the pipeline when subsequent reverse osmosis volume testing is performed, thus avoiding the influence of residual fluid on the test results and improving the accuracy of assessing the creep degree of the one-way valve.

[0079] pass Figure 2 The process of the one-way valve detection device in the server rack for detecting the one-way valve is as follows: In response to the server rack's shutdown command, the controller 214 controls the solenoid valve 216 to open, and at the same time, the pump group 218 discharges the fluid in the corresponding pipe of the server rack; then, based on the discharge result that the fluid is emptied, the controller 214 controls the solenoid valve to close, so that the server rack enters a static state, and the flow meter 212 records the liquid level in the liquid storage tank 220 at this time, and records the liquid level again after a period of time; then, based on the change between the two recorded liquid level positions, the total volume of the reverse osmosis fluid is determined, and the creep degree of the one-way valve is determined, thus completing the state detection of the one-way valve.
