[0002] As a data center construction model, containerized data centers offer advantages such as rapid deployment and flexible expansion. Their modular design effectively addresses challenges like long construction cycles and complex engineering. To ensure adequate heat dissipation and stable operation, existing containerized data centers typically use cooling equipment. However, this equipment often recycles water, leading to deteriorating water quality over time, potentially causing blockages, corrosion, and even damage. Therefore, setting conductivity thresholds or wastewater discharge cycles can control wastewater discharge. However, excessively high thresholds or cycles result in infrequent discharges, increasing the risk of unplanned emergency maintenance due to filter clogging. Conversely, excessively low thresholds or cycles lead to frequent discharges, wasting water resources. Summary of the Invention

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] The following is a description of the terminology used in the embodiments of this application:

[0029] I. Cloud Technology

[0030] Cloud technology is a collective term for network technologies, information technologies, integration technologies, management platform technologies, and application technologies applied based on the cloud computing business model. It can form resource pools, providing flexible and convenient on-demand access. Cloud computing technology will become a crucial support. Backend services of technical network systems require substantial computing and storage resources, such as video websites, image websites, and many portal websites. With the rapid development and application of the internet industry, every item may have its own identification mark in the future, requiring transmission to backend systems for logical processing. Data at different levels will be processed separately, and various industry data will all require robust system support, which can only be achieved through cloud computing.

[0031] II. Artificial Intelligence

[0032] Artificial intelligence (AI) is the theory, methods, technology, and application systems that use digital computers or machines controlled by digital computers to simulate, extend, and expand human intelligence, perceive the environment, acquire knowledge, and use that knowledge to achieve optimal results. In other words, AI is a comprehensive technology within computer science that attempts to understand the essence of intelligence and produce a new kind of intelligent machine that can react in a way similar to human intelligence. AI studies the design principles and implementation methods of various intelligent machines, enabling them to possess the functions of perception, reasoning, and decision-making.

[0033] III. Blockchain

[0034] Blockchain is a novel application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanisms, and cryptographic algorithms. Essentially, a blockchain is a decentralized database, a chain of data blocks linked together using cryptographic methods. Each data block contains information about a batch of network transactions, used to verify the validity of the information (anti-counterfeiting) and generate the next block. A blockchain can include an underlying platform, a platform product service layer, and an application service layer.

[0035] IV. Indirect Evaporation Cooling

[0036] The process of cooling air by transferring the cooling capacity of the humid air (secondary air) obtained by direct evaporation and cooling to the air to be treated (primary air) through a non-direct contact heat exchanger achieves the process of cooling air with equal humidity.

[0037] V. Electrical Conductivity

[0038] Cross-sectional area 1 square centimeter (cm) 2Conductivity is the electrical conductivity of a water column with a height of 1 cm. The unit of conductivity is Siemens per centimeter (S / cm). It represents the ability of an aqueous solution to conduct electric current and is closely related to the mineral content in the water. It can be used to detect changes in the concentration of dissolved minerals in water and to estimate the amount of ionic compounds in water.

[0039] VI. Water pump (or sprinkler pump)

[0040] Machinery that transports or pressurizes liquids can draw liquids from lower elevations and transport them along pipelines to higher elevations.

[0041] This application focuses on refrigeration equipment. Figure 1 Taking the indirect evaporative cooling air conditioning unit shown as an example, the operating modes of this air conditioning unit are briefly introduced first. This unit has three operating modes: dry mode, wet mode, and mixed mode. When the operating mode is dry mode, heat exchange is achieved only through air. Specifically, the primary side return air (i.e., indoor air) enters the air-to-air heat exchanger and exchanges heat with the secondary side intake air (i.e., outdoor air) entering the air-to-air heat exchanger. The primary side return air is cooled, and the secondary side intake air is heated. Then, the primary side outlet air (i.e., the cooled primary side return air) is directly sent into the room by the primary side fan. The air vents allow secondary side air (i.e., heated secondary side air intake) to be directly discharged outdoors via a secondary side fan. When the outdoor temperature is high, direct heat exchange between indoor and outdoor air cannot meet the cooling demand. The operating mode can be either wet or mixed. In both wet and mixed modes, the spray system is activated. A water circulation device (e.g., a water pump or spray pump) delivers water from the storage tank to the nozzles, which then spray the water onto the core surface of the air-to-air heat exchanger. As the water evaporates on the core surface, it absorbs heat from the air-to-air heat exchanger surface, further reducing the temperature of the primary side air supply. The storage tank, also known as a water collection pan or reservoir, is located at the bottom of the air-to-air heat exchanger. The sprayed water flows back to the storage tank after flowing across the surface of the air-to-air heat exchanger, thus achieving water recycling. In addition to the spray system, the mixed mode also activates the condenser and variable frequency compressor to further reduce the temperature of the primary side air supply.

[0042] The nozzle orifice diameter is generally between 1 and 2.5 millimeters (mm), which is easily clogged by large particles of impurities. Therefore, a filter screen is installed on the delivery pipeline of the water circulation device. Since the air conditioning unit is in direct contact with outdoor air, impurities, dust, and other dust in the outdoor air will adhere to the surface of the core or be deposited in the water storage device after long-term operation. If the water is not discharged for a long time, it will easily cause the filter screen to become clogged.

[0043] It should be noted that during long-term operation, the equipment will inevitably be affected by impurities in the water, such as filter clogging and scale buildup in the core. These cannot be cleaned by simply draining the water and changing it. Regular maintenance and cleaning by maintenance personnel are required. If the recommended maintenance cycle for the unit is once a quarter, then the air conditioning unit can be cleaned once every quarter.

[0044] To prevent unplanned emergency maintenance events due to filter clogging during maintenance periods, a conductivity threshold can be preset. When the conductivity of the water in the storage device exceeds the threshold, the device will be drained. For example, if the conductivity exceeds 1300 uS / cm (micro Siemens per centimeter). However, conductivity can only be used as an indicator of water contamination by minerals. This means that conductivity will increase when inorganic acids, alkalis, or salts in the water increase, but conductivity will not increase when organic matter increases. This is because organic impurities do not dissociate or dissociate very weakly, resulting in very weak conductivity. Excessive organic impurities can lead to filter clogging. Therefore, automatic draining based solely on conductivity does not fully account for the possibility of filter clogging caused by organic impurities. In addition, a sewage discharge cycle can be preset. When the sewage discharge cycle is reached, the water storage device will be drained. However, the water quality varies greatly in different regions (southern and northern regions). Even in the same region, the time cycle for filter clogging will vary due to differences in air environment and humidity. Therefore, a sewage discharge cycle can only be set based on the experience of the operation and maintenance personnel.

[0045] Meanwhile, when the conductivity threshold or sewage discharge cycle is set too high, the number of sewage discharges is low, but unplanned emergency maintenance events may still occur due to filter clogging. Conversely, when the conductivity threshold or sewage discharge cycle is set too low, frequent sewage discharges are likely, resulting in water waste. It is evident that manually setting the conductivity threshold or sewage discharge cycle makes accurate sewage discharge control difficult. Therefore, this application proposes an improved management scheme, specifically an equipment management scheme. This scheme includes: determining whether the pressure value at the water circulation device of the target equipment is within the alarm range; when the pressure value at the water circulation device is within the alarm range, it indicates a filter clogging event; adjusting the sewage discharge control parameters to obtain the adjusted sewage discharge control parameters; and using the adjusted sewage discharge control parameters to control the sewage discharge operation of the target equipment's water storage device. This scheme can obtain the optimal sewage discharge control parameters through dynamic adjustment, ensuring that filter clogging events do not occur before regular maintenance and cleaning, improving the accuracy of sewage discharge control and water resource utilization, and achieving effective management of refrigeration equipment.

[0046] The device management solution provided in this application can be applied to various fields or scenarios such as cloud technology, artificial intelligence, blockchain, vehicle networking, smart transportation, and smart homes. In one embodiment, the device management solution can be applied to a cloud technology scenario. Specifically, the device management solution can be implemented using cloud technologies involved in the cloud technology scenario; for example, sewage control parameters can be stored in a cloud server, or the refrigeration equipment can be managed by the cloud server, and so on.

[0047] In another implementation, the device management solution provided in this application can be applied to artificial intelligence (AI) scenarios. Specifically, this device management solution can utilize one or more implementations of distributed storage and big data processing technologies, which are fundamental AI technologies involved in AI scenarios. For example, in the device management solution of this application, the sewage control parameters of each refrigeration device can be stored using distributed storage.

[0048] In another embodiment, the device management scheme provided in this application can be applied to a blockchain scenario. For example, in the device management scheme of this application, the data required to execute the device management scheme can be stored on the blockchain in the form of blocks; the data generated by executing the device management scheme (such as sewage control parameters, pressure values, etc.) can be stored on the blockchain in the form of blocks; in addition, the computer device executing the device management scheme can be a node device in the blockchain network.

[0049] The device management scheme (i.e., the improved management scheme) proposed in the embodiments of this application will be described in detail below.

[0050] Please see Figure 2 This is a schematic diagram of the system architecture of a device management system provided in an embodiment of this application;

[0051] Figure 2 The system architecture shown can be used to implement the device management method proposed in the embodiments of this application. For example... Figure 2 As shown, the system architecture includes: a control server 20 and multiple target devices 21 (three are shown as an example in the figure).

[0052] The control server 20 can be a server with data processing capabilities. The server can be a standalone physical server, a server cluster (e.g., a container data center), or a distributed system. It can also be a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms. The target device 21 can be a refrigeration device, such as an indirect evaporative cooling air conditioning unit. Figure 1 The target device 21 shown is connected to the control server 20 via a network. There can be dozens or hundreds of target devices 21, or even more. This application does not limit the number of target devices.

[0053] Figure 2 The system architecture shown can implement the device management method provided in the embodiments of this application. The implementation process of this method generally includes:

[0054] ① The control server 20 obtains the pressure value at the water circulation device of the target device 21.

[0055] ② When the control server 20 determines that the pressure value at the water circulation device is within the alarm range, it acquires the sewage discharge control parameters, which include one or both of the conductivity threshold and the sewage discharge cycle.

[0056] ③ The control server 20 adjusts the sewage control parameters according to the first adjustment parameter of the sewage control parameters to obtain the adjusted sewage control parameters.

[0057] ④ The control server 20 controls the sewage discharge operation of the water storage device of the target equipment 21 according to the adjusted sewage discharge control parameters.

[0058] In one implementation, the control server 20 can send a sewage discharge command to the controller of the target device 21. The controller of the target device 21 responds to the sewage discharge command by activating the electric valve to discharge the sewage from the water storage device. When discharging the sewage from the water storage device, the controller of the target device 21 can pause the sprinkler system and replenish new water after all the sewage in the water storage device has been drained. Alternatively, the sprinkler system can continue operating, discharging the sewage in the water storage device to a low level before replenishing new water.

[0059] In one embodiment, multiple target devices 21 can be used to cool the container data center. The control server 20 can control the sewage discharge of the multiple target devices 21 to ensure that the multiple target devices can operate normally, thereby maximizing the heat dissipation of the container data center and ensuring the stable operation of the container data center.

[0060] In the above method, when the pressure value at the water circulation device is determined to be within the alarm range, the sewage control parameters can be dynamically adjusted to ensure that no filter clogging occurs before regular maintenance and cleaning. This can improve the accuracy of sewage control and the utilization rate of water resources, and achieve effective management of refrigeration equipment.

[0061] It is understood that the system architecture diagrams described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0062] The above provides a brief overview of the device management method provided in the embodiments of this application. The specific implementation of the device management method will be described in detail below.

[0063] Please see Figure 3 , Figure 3 A flowchart illustrating a device management method provided in this application embodiment. Figure 1 This equipment management method can be provided by... Figure 2 The control server 20 executes the method. This method includes the following steps S301-S303:

[0064] S301. Obtain the pressure value at the water circulation device of the target equipment.

[0065] The target equipment can be a refrigeration device, such as an indirect evaporative cooling air conditioning unit. This application does not limit the number of target equipment. The following steps are described using one target equipment as an example.

[0066] The water circulation device is used to transport water from the water storage device. The inlet of the water circulation device can be connected to the water storage device through a delivery pipeline, and the outlet of the water circulation device can be connected to the nozzle through a delivery pipeline. Filter screens are usually installed at the inlet and / or outlet of the water circulation device to improve water quality. There are usually two installation methods for the filter screens: one is that the pore size of the filter screen at the inlet is smaller than that at the outlet (and the pore size of the filter screen at the inlet must be smaller than the orifice of the nozzle), that is, precision filtration at the inlet and coarse filtration or no filtration at the outlet, in which case the filter screen at the inlet is prone to clogging; the other is that the pore size of the filter screen at the inlet is larger than that at the outlet, that is, coarse filtration at the inlet and precision filtration at the outlet, in which case the filter screen at the outlet is prone to clogging.

[0067] In one implementation, a water pressure sensor can be installed at the outlet, and the water pressure value measured by the sensor is used as the pressure value at the water circulation device. When the pressure value at the water circulation device is too high, it indicates that the drainage at the outlet is insufficient and the filter screen at the outlet is clogged; when the pressure value at the water circulation device is too low, it indicates that the inflow rate at the inlet is insufficient and the filter screen at the inlet is clogged.

[0068] In one embodiment, the control server can monitor the pressure value at the water circulation device of the target device in real time, or it can acquire the pressure value at the water circulation device of the target device at intervals (e.g., 5 seconds). Alternatively, the controller of the target device can send the pressure value at the water circulation device to the control server at intervals (e.g., 5 seconds).

[0069] S302. If the pressure value at the water circulation device is within the alarm range, then obtain the sewage discharge control parameters, which include one or both of the conductivity threshold and the sewage discharge cycle.

[0070] The alarm range is the range of pressure values ​​at the water circulation device when the filter is clogged. In one embodiment, the alarm range is as follows: Figure 4 As shown, Figure 4 The first threshold is the pressure value at the water circulation device when the outlet of the water circulation device is blocked. Figure 4 The second threshold is the pressure value at the water circulation device when the inlet of the water circulation device is blocked. Therefore, when the pressure value at the water circulation device is greater than or equal to the first threshold, it indicates that the filter screen at the outlet is blocked, and the pressure value at the water circulation device is determined to be in the alarm range; or, when the pressure value at the water circulation device is less than or equal to the second threshold, it indicates that the filter screen at the inlet is blocked, and the pressure value at the water circulation device is determined to be in the alarm range.

[0071] In one embodiment, when the inlet is used for coarse filtration and the outlet for fine filtration, to avoid nozzle clogging, such as... Figure 1 As shown, a filter can be installed in the delivery pipeline of the water circulation device. The water filtered at the outlet needs to be further filtered before being delivered to the nozzles. In this step, water pressure sensors can also be installed at the outlets of both the filter and the water circulation device. When the water pressure at the filter outlet differs significantly from that at the water circulation device outlet, it indicates a blockage in the filter. The difference between the water pressure at the filter outlet and the water circulation device outlet when the filter is blocked can be used as a third threshold. When the difference between the water pressure at the filter outlet and the water circulation device outlet is greater than or equal to the third threshold, it indicates a blockage in the filter, and the pressure value at the water circulation device is determined to be within the alarm range.

[0072] When the pressure value at the water circulation device is within the alarm range, it indicates that a filter clogging event has occurred during the maintenance period. The control server obtains the discharge control parameters, which include one or both of the following: conductivity threshold and discharge cycle. Specifically, the discharge control parameters may include the conductivity threshold, the discharge cycle, or both. In one implementation, the obtained discharge control parameters can be those initially set by the maintenance personnel, such as setting the conductivity threshold to 1300 uS / cm and the discharge cycle to once every 8 hours; or they can be the discharge control parameters after the last dynamic adjustment. For example, if the filter clogging occurs when the conductivity threshold is 1300 uS / cm, and the threshold is adjusted to 1000 uS / cm, and the filter clogging occurs again when the conductivity threshold is 1000 uS / cm, then 1000 uS / cm is used as the discharge control parameter.

[0073] S303. Adjust the sewage control parameters according to the first adjustment parameter of the sewage control parameters to obtain the adjusted sewage control parameters. The adjusted sewage control parameters are used to control the sewage discharge operation of the water storage device of the target equipment.

[0074] The occurrence of filter clogging during maintenance indicates that the frequency of sewage discharge is too low. This application can increase the frequency of sewage discharge during maintenance by reducing the sewage discharge control parameters. For example, if the original conductivity threshold was 1300 uS / cm, it can be changed to 1000 uS / cm. Previously, it took 14 hours for the water in the storage device to reach a conductivity of 1300 uS / cm. After adjusting to 1000 uS / cm, it only takes 8 hours for the water in the storage device to reach a conductivity of 1300 uS / cm. As another example, if the original sewage discharge cycle was once every 8 hours, changing the sewage discharge cycle to once every 5 hours will allow sewage to be discharged once every 5 hours.

[0075] When the downward adjustment of the sewage discharge control parameters is too large, frequent sewage discharge is likely to occur, resulting in a waste of water resources. To solve this problem, this application uses a successive approximation algorithm to determine the first adjustment parameter of the sewage discharge control parameters, and uses the first adjustment parameter to determine the downward adjustment range of the sewage discharge control parameters, including:

[0076] ① Obtain the maintenance cycle of the target equipment and the adjustment step size and proportional coefficient of the sewage control parameters.

[0077] The maintenance cycle of the target equipment refers to the frequency of maintenance and cleaning of the target equipment. It can be preset. For example, if the maintenance cycle of the target equipment is set to once every 3 months, then the target equipment will be maintained and cleaned once every 3 months.

[0078] The adjustment step size of the sewage control parameters can be preset. For example, the adjustment step size can be set to 100 μS / cm for the conductivity threshold, or 2 hours for the sewage discharge cycle. The proportional coefficient of the sewage control parameters can also be preset and is mainly used to adjust the adjustment step size. For example, if the proportional coefficient is set to 2.0 and the adjustment step size is set to 100 μS / cm, then the actual adjustment step size is 200 μS / cm.

[0079] ② Determine the alarm interval time of the target device.

[0080] The alarm interval can be determined by the time point when the pressure value at the water circulation device was last in the alarm range. For example, if the last time the pressure value at the water circulation device was in the alarm range was 12:00:00 on [date], and the next time the pressure value was in the alarm range was 12:00:00 on [date], then the alarm interval is 30 days. Alternatively, the alarm interval can be determined by the time point at the start of the maintenance cycle. For example, if the maintenance cycle starts at 12:00:00 on [date], and the pressure value at the water circulation device is in the alarm range at 12:00:00 on [date], then the alarm interval is 30 days.

[0081] ③ Determine the first adjustment parameter of the sewage control parameters based on the alarm interval, maintenance cycle, adjustment step size and proportional coefficient.

[0082] In one embodiment, a stepwise approximation algorithm can be used to determine the first adjustment parameter of the sewage control parameters, and the specific determination method is shown in the following equation (1):

[0083] First adjustment parameter = (maintenance cycle / alarm interval) × adjustment step size × proportional coefficient (1)

[0084] In one embodiment, the sewage control parameters include a conductivity threshold. The first adjustment parameter of the conductivity threshold is obtained according to the above formula (1). For example, if the maintenance cycle is 3 months (or 90 days), the alarm interval is 1 month (or 30 days), the adjustment step is 100 uS / cm, and the proportional coefficient is 1, then the first adjustment parameter of the conductivity threshold obtained by using the above formula (1) is 300 uS / cm.

[0085] In one embodiment, the sewage control parameters include the sewage cycle. The first adjustment parameter of the sewage cycle is obtained according to the above formula (1). For example, if the maintenance cycle is 3 months, the alarm interval is 1 month, the adjustment step is 2 hours, and the proportional coefficient is 1, then the first adjustment parameter of the sewage cycle is 6 hours using the above formula (1).

[0086] In one embodiment, the sewage control parameters include the sewage discharge cycle and the conductivity threshold. The first adjustment parameters of the conductivity threshold and the sewage discharge cycle can be obtained according to the above formula (1).

[0087] ④ Adjust the sewage control parameters according to the first adjustment parameter of the sewage control parameters to obtain the adjusted sewage control parameters.

[0088] In one embodiment, the discharge control parameters are adjusted downward according to a first adjustment parameter to obtain adjusted discharge control parameters. For example, if the discharge control parameters include a conductivity threshold of 1300 μS / cm and the first adjustment parameter for the conductivity threshold is 300 μS / cm, then the adjusted conductivity threshold is 1000 μS / cm. Another example is if the discharge control parameters include a discharge cycle of 8 hours and the first adjustment parameter for the discharge cycle is 6 hours, then the adjusted discharge cycle is 2 hours.

[0089] In one embodiment, the sewage control parameters include a conductivity threshold and a sewage discharge cycle. The control server can adjust the conductivity threshold and the sewage discharge cycle by adjusting either one according to the corresponding first adjustment parameter, or it can adjust both of the conductivity threshold and the sewage discharge cycle according to the corresponding first adjustment parameter.

[0090] In the above embodiments, the first adjustment parameter is obtained by the stepwise approximation algorithm. The sewage control parameter is then adjusted down using the first adjustment parameter. This ensures that the refrigeration equipment does not experience filter clogging during the maintenance cycle (or before regular maintenance and cleaning). Maintenance personnel do not need to perform emergency maintenance events outside of the plan. This can improve the accuracy of sewage control and the utilization rate of water resources, and achieve effective management of the refrigeration equipment.

[0091] In one embodiment, the adjustment control range of the sewage control parameters can be preset. For example, if the upper limit of the conductivity threshold is set to 1900 uS / cm and the lower limit is set to 800 uS / cm, then the adjustment control range of the conductivity threshold is [800, 1900]. As another example, if the upper limit of the sewage discharge cycle is set to 72 hours and the lower limit is set to 4 hours, then the adjustment control range of the sewage discharge cycle is [4, 72].

[0092] In one implementation, the control server can detect whether the discharge control parameter is higher than the lower limit of the aforementioned adjustment control range. If the discharge control parameter is higher than the lower limit of the adjustment control range, it indicates that the discharge control parameter can be further adjusted downwards. For example, if the adjustable lower limit is 800 uS / cm and the discharge control parameter is 1300 uS / cm, it indicates that it can be further adjusted downwards. The control server then performs the step of adjusting the discharge control parameter according to the first adjustment parameter of the discharge control parameter to obtain the adjusted discharge control parameter. If the discharge control parameter is lower than the lower limit of the adjustment control range, it indicates that the discharge control parameter cannot be further adjusted downwards. If the adjustable lower limit is set to 800 uS / cm and the sewage control parameter is set to 700 uS / cm, it indicates that further reduction is not possible. In this case, the control server can generate an alarm message and send it to the target terminal device (which can be the terminal device used by the maintenance personnel). The alarm message can prompt the maintenance personnel to shorten the maintenance cycle to ensure that no filter clogging occurs within the newly set maintenance cycle; it can also prompt the maintenance personnel to check and replenish the water quality to maintain the normal operation of the refrigeration equipment; and it can also prompt the maintenance personnel to initiate emergency maintenance and cleaning, allowing them to clean the filter, water storage device, air-to-air heat exchanger, etc.

[0093] In one embodiment, if the adjusted sewage control parameter is lower than the lower limit of the adjustment control range of the sewage control parameter, the sewage discharge operation of the water storage device of the target equipment can be directly controlled by the lower limit of the adjustment control range. For example, if the lower limit of the adjustment control range of the conductivity threshold is 800 uS / cm, then the sewage discharge operation of the water storage device of the target equipment is controlled by 800 uS / cm. Or, if the lower limit of the adjustment control range of the sewage discharge cycle is 4 hours, then the sewage discharge operation of the water storage device of the target equipment is controlled by 4 hours.

[0094] In one embodiment, a conductivity sensor can be installed in the water storage device of the target device. The control server can obtain the conductivity of the water in the water storage device of the target device based on the conductivity sensor. When the conductivity of the water in the water storage device is greater than or equal to the conductivity threshold (i.e., the adjusted conductivity threshold) included in the adjusted sewage discharge control parameters, a sewage discharge operation is performed on the water storage device of the target device. For example, if the conductivity threshold is 1000 uS / cm, when the conductivity of the water in the water storage device is 1000 uS / cm, the control server can send a sewage discharge command to the controller of the target device. The controller of the target device then controls the electric valve to discharge the sewage in the water storage device and inject new water.

[0095] In another embodiment, the control server can perform a sewage discharge operation on the water storage device of the target device when the sewage discharge cycle (i.e., the adjusted sewage discharge cycle) included in the adjusted sewage discharge control parameters is reached. For example, if the sewage discharge cycle is once every three hours and the current time point is three hours away from the time point of the last sewage discharge, the control server can send a sewage discharge command to the controller of the target device, and the controller of the target device can control the electric valve to discharge the sewage in the water storage device and inject new water.

[0096] In this embodiment, when the pressure value at the water circulation device of the target equipment is within the alarm range, the sewage control parameters (one or both of conductivity threshold and sewage cycle) can be adjusted according to the first adjustment parameter of the sewage control parameters to obtain the adjusted sewage control parameters. The sewage discharge operation of the water storage device of the target equipment is then controlled according to the adjusted sewage control parameters. The above scheme can improve the accuracy of sewage control and the utilization rate of water resources by dynamically adjusting the sewage control parameters, avoid the occurrence of blockage events, and achieve effective management of refrigeration equipment.

[0097] Please see Figure 5 , Figure 5 A flowchart illustrating a device management method provided in this application embodiment. Figure 2 This equipment management method can be provided by... Figure 2 The control server 20 in the middle executes the following, including S501-S503:

[0098] S501. Obtain the pressure value at the water circulation device of the target equipment.

[0099] For a detailed description of S501, please refer to S301; it will not be repeated in this embodiment.

[0100] S502. If the pressure value at the water circulation device is outside the alarm range within a preset time, then determine the second adjustment parameter of the sewage control parameter.

[0101] The preset time can be manually set, and can be the maintenance cycle of the target equipment. When the pressure value at the water circulation device is outside the alarm range within the preset time, it indicates that no filter clogging event has occurred in the target equipment within the entire preset time. At this time, the number of times the target equipment is discharged may be too many. This application can reduce the number of times the discharge is discharged during the maintenance period by increasing the discharge control parameters. For example, when no filter clogging event occurs within the maintenance cycle, if the original conductivity threshold is 1000 uS / cm, the conductivity threshold can be changed to 1300 uS / cm. Originally, it took 8 hours for the conductivity of the water in the water storage device to reach 1000 uS / cm. After adjusting to 1300 uS / cm, it takes 14 hours for the conductivity of the water in the water storage device to reach 1300 uS / cm. As another example, if the original discharge cycle is once every 5 hours, after changing the discharge cycle to 8 hours, sewage will be discharged once every 8 hours.

[0102] When the upward adjustment of the sewage discharge control parameters is too large, filter clogging is likely to occur. To solve this problem, this application uses linear interpolation to determine the second adjustment parameter of the sewage discharge control parameters, and uses the second adjustment parameter to determine the upward adjustment range of the sewage discharge control parameters, including:

[0103] ① The reference pressure value is determined based on the first threshold and the second threshold. The first threshold is determined based on the pressure value at the water circulation device when the outlet of the water circulation device is blocked, and the second threshold is determined based on the pressure value at the water circulation device when the inlet of the water circulation device is blocked.

[0104] The reference pressure value is the pressure when the filter is not clogged. The reference pressure value is as follows: Figure 4 As shown, it is located between the first threshold and the second threshold, and can be specifically determined by the following formula (2):

[0105] Reference pressure value = (first threshold - second threshold) / 2 (2)

[0106] ② Determine the optimal pressure value based on the target optimization range of the pressure value at the water circulation device.

[0107] like Figure 4 As shown, the target optimization interval is close to the first threshold or the second threshold. The size of the target optimization interval can be set manually. For example, when the first threshold is 5, the target optimization interval is set to [4.7, 5], and when the second threshold is 1, the target optimization interval is set to [1, 1.3].

[0108] In one implementation, the optimization pressure value can be the median of the target optimization interval, or any pressure value included in the target optimization interval.

[0109] ③ Obtain the adjustment step size and proportional coefficient of the sewage discharge control parameters.

[0110] ④ Determine the second adjustment parameter of the sewage control parameters based on the reference pressure value, the optimized pressure value, the pressure value at the water circulation device, the adjustment step size, and the proportional coefficient.

[0111] In one embodiment, the second adjustment parameter of the sewage control parameters can be determined by linear interpolation, and the specific determination method is shown in the following equation (3):

[0112] Second adjustment parameter = adjustment step size × (reference pressure value - optimized pressure value) / (reference pressure value - pressure value at the water circulation device) × proportional coefficient K (3)

[0113] It should be noted that when the pressure value at the water circulation device is the water pressure value measured by the water pressure sensor at the inlet, if the pressure value at the water circulation device is less than or equal to the reference pressure value, the optimized pressure value is determined by a target optimization range close to the second threshold. For example, if the target optimization range close to the second threshold is [1, 1.3], then 1.2 can be used as the optimized pressure value. If the pressure value at the water circulation device is greater than or equal to the reference pressure value, the optimized pressure value is determined by a target optimization range close to the first threshold. For example, if the target optimization range close to the first threshold is [4.7, 5], then 4.8 can be used as the optimized pressure value.

[0114] In one implementation, if the pressure value at the water circulation device is the difference between the water pressure value at the outlet of the filter and the water pressure value at the outlet of the water circulation device, then the reference pressure value is the difference between the water pressure value at the outlet of the filter and the water pressure value at the outlet of the water circulation device when the filter is not clogged. The optimized pressure value is determined by a target optimization range close to the third threshold. For example, if the target optimization range close to the third threshold is [4, 5], then 4.5 can be used as the optimized pressure value.

[0115] In one embodiment, the sewage control parameters include a conductivity threshold. Then, a second adjustment parameter for the conductivity threshold is obtained according to the above equation (3), for example: Figure 6 As shown, the reference pressure is 3 Bar, the optimized pressure is 1.2 Bar, and the pressure at the water circulation device is 2 Bar. In addition, the proportional coefficient is 1 and the adjustment step is 100 uS / cm. Then, the second adjustment parameter for the conductivity threshold obtained by using the above formula (3) is 180 uS / cm.

[0116] In one embodiment, the sewage control parameters include the sewage cycle. The second adjustment parameter of the sewage cycle is obtained according to the above formula (3). For example, the reference pressure value is 3 Bar, the optimized pressure value is 1.2 Bar, the pressure value at the water circulation device is 2 Bar, the proportional coefficient is 1, and the adjustment step size is 2 hours. The second adjustment parameter of the sewage cycle is 3.6 hours obtained by using the above formula (3).

[0117] In one embodiment, the sewage control parameters may include the sewage discharge cycle and the conductivity threshold, and the second adjustment parameters of the conductivity threshold and the sewage discharge cycle can be obtained according to the above equation (3).

[0118] In one embodiment, the adjustment control range of the sewage control parameters can be preset. For example, if the upper limit of the conductivity threshold is set to 1900 uS / cm and the lower limit is set to 800 uS / cm, then the adjustment control range of the conductivity threshold is [800, 1900]. As another example, if the upper limit of the sewage discharge cycle is set to 72 hours and the lower limit is set to 4 hours, then the adjustment control range of the sewage discharge cycle is [4, 72].

[0119] In one implementation, the control server can detect whether the sewage control parameter is higher than the upper limit of the aforementioned adjustment control range. If the sewage control parameter is higher than the upper limit of the adjustment control range, it indicates that the sewage control parameter cannot be further increased. At this time, the control server can generate a prompt message and send the prompt message to the target terminal device (which may be the terminal device used by the maintenance personnel). The prompt message can remind the maintenance personnel to extend the maintenance cycle. If the sewage control parameter is lower than the upper limit of the adjustment control range, it detects whether the pressure value at the water circulation device is outside the target optimization range. If the pressure value at the water circulation device is outside the target optimization range, it executes the step of determining the second adjustment parameter of the sewage control parameter. If the pressure value at the water circulation device is within the target optimization range, there are two situations: one is that the time point for regular maintenance and cleaning is about to be reached, in which case water resources are being utilized to the maximum extent, and blockage events are being ensured during the maintenance period; the other is that the time point for regular maintenance and cleaning still needs some time to be reached, in which case the pressure value at the water circulation device may continue to increase or decrease until it is within the alarm range, in which case S301-S303 are used for processing.

[0120] In one embodiment, if the adjusted sewage control parameter is higher than the upper limit of the adjustment control range of the sewage control parameter, the upper limit of the adjustment control range can be used to directly control the sewage discharge operation of the water storage device of the target equipment. For example, if the upper limit of the adjustment control range of the conductivity threshold is 1900 uS / cm, then 1900 uS / cm is used to control the sewage discharge operation of the water storage device of the target equipment. Or, if the upper limit of the adjustment control range of the sewage discharge cycle is 18 hours, then 18 hours is used to control the sewage discharge operation of the water storage device of the target equipment.

[0121] S503. Adjust the sewage control parameters according to the second adjustment parameter of the sewage control parameters to obtain the adjusted sewage control parameters. The adjusted sewage control parameters are used to control the sewage discharge operation of the water storage device of the target equipment.

[0122] In one embodiment, the sewage control parameters are adjusted upwards according to the second adjustment parameter of the sewage control parameters to obtain the adjusted sewage control parameters. For example, if the sewage control parameters include a conductivity threshold of 1300 μS / cm and the second adjustment parameter of the conductivity threshold is 180 μS / cm, then the adjusted conductivity threshold is 1480 μS / cm. As another example, if the sewage control parameters include a sewage discharge cycle of 8 hours and the second adjustment parameter of the sewage discharge cycle is 3.6 hours, then the adjusted sewage discharge cycle is 11.6 hours.

[0123] In one embodiment, the sewage control parameters include a conductivity threshold and a sewage discharge cycle. The control server can adjust either the conductivity threshold or the sewage discharge cycle upwards according to the second adjustment parameter, or it can adjust both of the conductivity threshold and the sewage discharge cycle upwards according to the second adjustment parameter.

[0124] In this embodiment, when the pressure value at the water circulation device of the target equipment is outside the alarm range, the sewage control parameters (one or both of conductivity threshold and sewage cycle) can be adjusted according to the second adjustment parameter of the sewage control parameters to obtain the adjusted sewage control parameters. The sewage discharge operation of the water storage device of the target equipment is then controlled according to the adjusted sewage control parameters. The above scheme can ensure that the pressure value at the water circulation device is within the target optimization range before regular maintenance and cleaning. It can prevent filter clogging while maximizing the use of water resources, improve the accuracy of sewage control and the utilization rate of water resources, and achieve effective management of refrigeration equipment.

[0125] Please see Figure 7 , Figure 7This diagram illustrates a human-machine interface provided in an embodiment of this application. In this interface, the maintenance cycle of the target equipment can be set. This maintenance cycle can be comprehensively set by maintenance personnel based on local water quality, climate, core material, and scaling conditions. For example, if the water quality is poor and scaling occurs quickly, a shorter maintenance cycle, such as 2 months, can be set. If the water quality and climate are good and scaling occurs slowly, a longer maintenance cycle, such as 4 months, can be set. The human-machine interface can also set sewage discharge control parameters, including a conductivity threshold and a sewage discharge cycle. As shown in the diagram, the conductivity threshold is set to 1300 μS / cm, and the sewage discharge cycle is once every 8 hours. In one implementation, the conductivity threshold can be set according to the equipment's water quality requirements. For example, if the core of an air-to-air heat exchanger requires a conductivity below 1300 μS / cm, then the set conductivity threshold can be 1300 μS / cm. The human-machine interface allows users to set adjustment ranges for sewage discharge control parameters. For example, the upper limit of the control range for conductivity threshold can be set to 1900 μS / cm, and the lower limit to 800 μS / cm. Similarly, the upper limit for the sewage discharge cycle can be set to 72 hours, and the lower limit to 4 hours. Furthermore, the adjustment step size and proportional coefficient of the sewage discharge control parameters can be set within the human-machine interface. For instance, the adjustment step size for conductivity threshold can be 100 μS / cm, the adjustment step size for sewage discharge cycle can be 2 hours, and the proportional coefficient can be 1.0. The human-machine interface can be configured for a single target device or multiple target devices.

[0126] During a maintenance cycle, one or more filter clogging events may occur. In one embodiment, when a filter clogging event occurs for the first time during a maintenance cycle, the conductivity threshold set in the human-machine interface and one or more of the discharge cycles can be used as discharge control parameters for dynamic adjustment. Alternatively, the conductivity threshold at the end of the previous maintenance cycle and one or more of the discharge cycles can be used as discharge control parameters for dynamic adjustment. In addition, when filter clogging events occur multiple times during a maintenance cycle, the discharge control parameters after the last adjustment can be used for further dynamic adjustment, ensuring that the discharge control parameters are continuously iterated and optimized.

[0127] In one embodiment, if the maintenance cycle is changed, for example, from 3 months to 2 months, it is not suitable to continue dynamically adjusting based on the discharge control parameters for 3 months. Therefore, a memory iteration function can be added to store the conductivity threshold and discharge cycle at the end of different maintenance cycles. The next maintenance cycle can continue to be dynamically adjusted based on the discharge control parameters of the previous maintenance cycle. For example, considering that the maintenance cycle generally does not exceed 4 months, it can be adjusted at half-month intervals using a... 11This represents the conductivity threshold corresponding to a maintenance cycle of half a month, denoted by a. 12 This indicates the sewage discharge cycle corresponding to a half-month maintenance cycle, denoted by 'a'. 21 The conductivity threshold corresponding to a one-month maintenance cycle is represented by a. 22 This represents the sewage discharge cycle corresponding to a one-month maintenance cycle, denoted by 'a'. 31 The conductivity threshold corresponding to a maintenance cycle of one and a half months is represented by a. 32 This indicates the sewage discharge cycle corresponding to a maintenance cycle of one and a half months, and so on. When a maintenance cycle ends, if the next maintenance cycle does not change (e.g., the previous maintenance cycle was 4 months, and the next maintenance cycle is also 4 months), then no changes are made. Iterative optimization can continue based on the sewage discharge control parameters of the previous maintenance cycle, and 'a' is updated according to the optimized sewage discharge control parameters. 81 and a 82 This ensures continued use during the next 4-month maintenance cycle. If the maintenance cycle changes, for example, from 4 months to 2 months, the corresponding sewage control parameters for the 2-month maintenance cycle can be indexed, allowing searching for parameters like 'a'. 41 and a 42 In memory of a 41 and a 42 Based on this, the discharge control parameters are iteratively optimized, and a is updated according to the optimized discharge control parameters. 41 and a 42 So that it can continue to be used in the next two-month maintenance cycle.

[0128] In another embodiment, the rate at which the filter becomes clogged varies with the season. Maintenance cycles can be set for different seasons. For example, in summer, when water usage is higher, clogging occurs faster, typically requiring a 2-month maintenance cycle. In winter, when temperatures are lower, clogging occurs more slowly, typically requiring a 3- or 4-month maintenance cycle. The conductivity threshold and drainage cycle at the end of the maintenance cycle can be recorded for different seasons (e.g., spring, summer, autumn, winter). For example, a, b, c, and d record the conductivity threshold and drainage cycle at the end of the maintenance cycle for each of the four seasons. If the current time is summer, index b can retrieve the conductivity threshold and drainage cycle at the end of the previous summer's maintenance cycle; if the current time is winter, index d can retrieve the conductivity threshold and drainage cycle at the end of the previous winter's maintenance cycle.

[0129] In feasible embodiments, instead of determining whether a filter clogging event has occurred by checking if the pressure value at the water circulation device is within the alarm range, a camera can be used to photograph, identify, and compare the filter clogging status to confirm whether a clogging event has occurred. Alternatively, the conductivity sensor can be replaced with a dedicated optical analysis device to analyze organic impurities in the water storage device. When the concentration of organic impurities exceeds a certain level, automatic discharge is initiated.

[0130] In one embodiment, the equipment management solution provided in this application can also be applied to other equipment with circulating water systems, such as refrigerator equipment, power generation equipment, factory equipment, etc., to provide sewage control for equipment with circulating water systems.

[0131] Please see Figure 8 , Figure 8 A flowchart illustrating a device management method provided in this application embodiment. Figure 3 This equipment management method can be provided by... Figure 2 The control server 20 in the middle performs the following tasks:

[0132] When the target equipment is operating normally, the pressure value at the water circulation device of the target equipment is acquired. If a filter clogging event occurs within the maintenance cycle (i.e., the pressure value at the water circulation device is within the alarm range), it is determined whether the sewage discharge control parameters (including one or both of conductivity threshold and sewage discharge cycle) are lower than the lower limit of the adjustment control range. If they are lower than the lower limit of the adjustment control range, an alarm message is generated and sent to the target terminal equipment. Maintenance personnel can perform emergency maintenance cleaning, shorten the maintenance cycle, etc., based on the alarm message. If they are higher than the lower limit of the adjustment control range, the sewage discharge control parameters are adjusted according to the first adjustment parameter to obtain the adjusted sewage discharge control parameters. The sewage discharge operation of the target equipment's water storage device is controlled according to the adjusted sewage discharge control parameters. If a filter clogging event still occurs within the maintenance cycle... If no filter clogging event occurs within the maintenance cycle (i.e., the pressure value at the water circulation device is outside the alarm range), then the system checks whether the discharge control parameters are higher than the upper limit of the adjustment control range. If they are higher than the upper limit, no dynamic adjustment is made to the discharge control parameters. If they are lower than the lower limit, and the pressure value at the water circulation device is within the target optimization range, no dynamic adjustment is made to the discharge control parameters. If they are lower than the lower limit, and the pressure value at the water circulation device is outside the target optimization range, then the discharge control parameters are adjusted according to the second adjustment parameter to obtain the adjusted discharge control parameters. The system then controls the discharge operation of the target equipment's water storage device according to the adjusted discharge control parameters.

[0133] In one embodiment, the sewage control parameters may include only the conductivity threshold or the sewage discharge cycle, in which case dynamic adjustment is performed only on the conductivity threshold or the sewage discharge cycle; or, the sewage control parameters may include both the conductivity threshold and the sewage discharge cycle, in which case dynamic adjustment can be performed on both the conductivity threshold and the sewage discharge cycle simultaneously, or dynamic adjustment can be performed on only one of the conductivity threshold and the sewage discharge cycle each time. For example, when a filter clogging event occurs, the conductivity threshold is dynamically adjusted first, and if a filter clogging event occurs again, the sewage discharge cycle can be dynamically adjusted then.

[0134] Through the above embodiments, a dynamic balance between water conservation and filter clogging can be achieved, ensuring that the target equipment is cleaned precisely when it is due for maintenance, reducing the pressure on maintenance personnel, eliminating the need to handle unplanned emergency maintenance events, improving the accuracy of sewage control and water resource utilization, and achieving effective management of refrigeration equipment.

[0156] Obtain the pressure value at the water circulation device of the target equipment;

[0157] If the pressure value at the water circulation device is within the alarm range, then the sewage control parameters are obtained. The sewage control parameters include one or both of the conductivity threshold and the sewage cycle.

[0158] The sewage control parameters are adjusted according to the first adjustment parameter of the sewage control parameters to obtain the adjusted sewage control parameters, which are used to control the sewage discharge operation of the water storage device of the target equipment.
