Description

Technical Field

[0001] The present invention relates to the technical field of vehicle driving control, and in particular to a method, device and electronic equipment for controlling power of a cooling system of a vehicle. Background Art

[0002] With the continuous upgrading of intelligent driving technology, the requirements for hardware computing power and stability in autonomous driving systems are becoming higher and higher. Autonomous driving usually requires processing a large amount of sensor data, running complex decision-making and vehicle control algorithms, etc. These processes usually cause the intelligent driving system to perform high-load operations, which in turn causes the temperature of the chips and circuit components of the relevant controllers in the intelligent driving system to rise. The temperature often affects the operating performance of the controller and may even cause intelligent driving system failures or hardware damage.

[0003] In the related art, in order to reduce the temperature of the controller, a cooling system such as air cooling or water cooling is usually used for cooling. For example, after detecting that the temperature of the cooling water reaches the threshold that requires cooling, the water cooling cycle is directly turned on or the rated power air cooling is turned on to cool the vehicle. For vehicles, power resources are extremely precious resources. However, traditional cooling systems will continue to consume a large amount of power resources during operation, resulting in a waste of power resources. Summary of the invention

[0042] In order to enable ordinary persons in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are only examples of devices and methods consistent with some aspects of the present invention. The terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, product or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, product or device. In the absence of more restrictions, it is not excluded that there are other identical or equivalent elements in the process, method, product or device including the elements. For example, if the words "first", "second", etc. are used to represent the name, they do not represent any specific order.

[0044] The vehicle cooling system power control method provided by the present invention can be applied to Figure 1 Cooling system shown. Figure 1 The present invention provides a schematic diagram of a cooling system structure including a water cooling system and a refrigerant cooling system. The method provided by the present invention can be implemented in a vehicle cooling system including at least two cooling systems. Figure 1 The implementation scenario shown may include a water cooling system and a refrigerant cooling system, and their main structures and functions are schematically described as follows. Figure 1As shown, the water cooling system 110 may include a closed water tank 01, a water pump motor 02, a composite cooling fin 03, a cooling water pressure sensor 04, a water inlet temperature sensor 05, a water cooling heat sink 15, a water outlet temperature sensor 06, a safety valve 07, etc. Among them, the closed water tank 01 is used to store cooling water. The water pump motor 02 can be used to provide power for the water cooling cycle. The cooling water pressure sensor 04 can be used to detect the pressure inside the cooling water pipeline. The water inlet temperature sensor 05 and the water outlet temperature sensor 06 can be used to detect the temperature of the cooling water flowing into and out of the radiator. The safety valve 07 is a protective switch under abnormal cooling water pressure. The water cooling heat sink 15 is usually connected to the chip of the controller or some other components, circuits, etc. that need heat dissipation, and is used to achieve heat dissipation of the chip or components, components, etc. The refrigerant cooling system 120 mainly cools the cooling water through the composite cooling fins, and mainly includes a low-pressure control switch 08, a compressor 09, a high-pressure control switch 10, a cooling fin 11, a cooling fan 12, an expansion valve 13, a dryer 14, a composite cooling fin 03, etc. In the refrigerant cooling system, the refrigerant enters the compressor 09 in a low-temperature and low-pressure gas state through the low-pressure control switch 08, and is compressed into a high-temperature and high-pressure refrigerant gas in the compressor 09. The high-temperature and high-pressure refrigerant gas passes through the high-pressure control switch 10 and then enters the cooling fin 11, and exchanges heat with the outside air through the cooling fin 11. After exchanging heat, the high-temperature and high-pressure refrigerant gas condenses into a high-pressure liquid. The condensed high-pressure liquid reduces the pressure through the expansion valve 13 to form a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid is dried by the dryer 14 and enters the composite cooling fin 03, where it absorbs the heat of the cooling water by evaporation and then converts into a gaseous state.

[0045] In some embodiments provided by the present invention, the cooling system may generally include a variety of different sub-cooling systems. For example, in the case of including two sub-cooling systems, it may include a water cooling system and a refrigerant cooling system. In application scenarios with more than two cooling systems, a third cooling system may also be included, such as an air cooling system or another refrigerant cooling system with a different cooling medium from the refrigerant cooling system. By analogy, the cooling system may also include a fourth cooling system, a fifth cooling system, and the like. In some embodiments provided by the present invention, the operation and control of the various sub-cooling systems in the cooling system may be controlled by a unified controller or by multiple controllers. These controllers may include a controller of a local terminal, such as an on-board controller, or a controller of a remote service end, such as a controller in a server that can communicate with the vehicle. In some embodiments, the controller of the local terminal and the controller of the service end may also assist in completing the control process of the cooling system. The local terminal described in the present invention may include, but is not limited to, various on-board devices, personal computers, laptops, smart phones, tablet computers, wearable devices, medical devices, VR (Virtual Reality) virtual devices, and the like. The server may also be a server, a server cluster, a distributed subsystem, a cloud processing platform, a server including a blockchain node, and a device combined therefrom. The controller of the present invention may include various control units capable of implementing logic processing functions, including but not limited to CPU (Central Processing Unit), PLC (Programmable Logic Controller), ECU (Electronic Control Unit), MCU (Microcontroller Unit), etc., as well as a controller composed of one or more logic function units, chips, etc.

[0046] In some embodiments provided by the present invention, the cooling system may generally include a variety of different sub-cooling systems. In some embodiments of the present invention, the multiple sub-cooling systems may be divided into multiple cooling systems, each cooling system may include one or more sub-cooling systems, and different cooling system control strategies may be activated according to different cooling requirements to achieve control of multiple cooling modes. For example, in an application scenario including two sub-cooling systems, a water cooling system and a refrigerant cooling system, the water cooling system may be determined as the first cooling system, and the refrigerant cooling system may be determined as the second cooling system. In other application scenarios including more than two sub-cooling systems, the sub-cooling system included in the first cooling system and the sub-cooling system included in the second cooling system may be customized and combined according to the power consumption, cooling efficiency and other requirements of the sub-cooling system. For example, the water cooling system and the air cooling system may be determined as the first cooling system. By analogy, the implementation scheme provided by the present invention does not exclude that a third cooling system, a fourth cooling system, etc. may also be included. The following is an example of the implementation scenario of the vehicle cooling system power control including two sub-cooling systems in the cooling system to illustrate the embodiment of the present invention. Figure 2 FIG. 1 is a schematic diagram of a partial hardware solution structure of a cooling system according to an exemplary embodiment. In this exemplary solution, the cooling system may include a water cooling system and a refrigerant cooling system. Figure 2 As shown, the MCU (or MCU control unit) can be connected to the cooling water pressure sensor, the outlet water temperature sensor, and the inlet water temperature sensor through A / D (analog-to-digital converter, used to convert analog quantities into digital quantities), and the temperature and pressure data of the cooling water can be collected. The MCU can be connected to the compressor control circuit in the compressor through PWM (Pulse-Width Modulation, pulse modulation), and the operation control of the refrigerant cooling system can be realized. The MCU can be connected to the cooling fan through PWM to control the air volume of the cooling fan. The MCU can communicate with the high-pressure / low-pressure control switch through I2C (Inter-Integrated Circuit, a bidirectional two-wire synchronous serial bus communication method) to obtain the pressure data of the refrigerant in the refrigerant cooling system.

[0047] Figure 3 The present invention is a flow chart of a method for controlling the power of a vehicle cooling system according to an exemplary embodiment, wherein the cooling system includes at least two cooling systems, and each of the at least two cooling systems in some embodiments of the present invention includes at least one sub-cooling system, and each cooling system may include different sub-cooling systems or the same sub-cooling system. Figure 3 As shown, the method may be implemented in a controller of a vehicle, and the method may include:

[0048] S30: Acquire cooling water temperature, where the cooling water temperature is determined based on monitored water inlet temperature and water outlet temperature.

[0049] In the case where the cooling system includes a water cooling system, the cooling water temperature can be obtained. The cooling water temperature generally refers to the temperature of the cooling water. In some embodiments of the present invention, the cooling water temperature may include cooling water temperature data detected by a temperature sensor, and may also include cooling water temperature data received from other terminals or servers, and may also include cooling water temperature data obtained through data identification / conversion. The inlet water temperature refers to the temperature of the cooling water monitored before the cooling water flows into the designated device, and the outlet water temperature generally refers to the temperature of the cooling water detected after flowing out of the designated device. The designated device may generally be a heat dissipation device.

[0050] In some embodiments of the present invention, the cooling water temperature can be determined based on the inlet water temperature and the outlet water temperature obtained by monitoring. In the cooling system, the cooling water temperature in different areas is different, and the cooling water temperature is one of the important parameters that affect the power regulation of the cooling system. Therefore, in some embodiments provided by the present invention, after receiving the inlet water temperature and outlet water temperature data from a temperature sensor or other parties, the inlet water temperature and the outlet water temperature can be further processed to obtain a more accurate cooling water temperature that is more suitable for the power regulation scenario of the cooling system. The processing of the inlet water temperature and the outlet water temperature can be achieved in a variety of ways, such as using the average value of the inlet water temperature and the outlet water temperature as the cooling water temperature, or performing temperature compensation on at least one of the inlet water temperature and the outlet water temperature according to other parameter information.

[0051] S32: When the cooling water temperature is lower than a first control threshold, control the cooling system to be in a non-operating state.

[0052] In some embodiments of the present invention, different control thresholds can be pre-set, and power control strategies of the cooling system corresponding to different cooling temperature intervals can be set by the control thresholds, so that power control of the cooling system with different strategies can be realized according to the real-time cooling water temperature. In some embodiments of the present invention, a first control threshold can be set. When the cooling water temperature is less than the first control threshold, the temperature can usually be reduced by natural cooling, which can reduce or reduce or even eliminate the need to start the cooling system, thereby reducing the power consumption of the cooling system. The control of the cooling system in a non-working state may include that a sub-cooling system in the cooling system is not started, or one or more of the sub-cooling systems are in a standby or low power consumption state, etc.

[0053] S34: When the cooling water temperature is between the first control threshold and the second control threshold, start the first cooling system in the cooling system and adjust the power of the first cooling system according to a first temperature difference, wherein the first temperature difference is determined based on the cooling water temperature and the first control threshold, and the second control threshold is greater than the first control threshold.

[0054] In some embodiments of the present invention, a second control threshold may also be set, and the second control threshold is greater than the first control threshold. In some application scenarios, the sub-cooling system with relatively low power consumption can usually be set as the first cooling system. When the cooling water temperature is between the first control threshold and the second control threshold, the first cooling system can be started for cooling. In the process of enabling the first cooling system for cooling, the second cooling system in the cooling system can be controlled to be in a non-working state, such as controlling the second cooling system to be in a low power consumption mode.

[0055] In some embodiments of the present invention, the power of the first cooling system can be adjusted according to the first temperature difference between the cooling water temperature and the first control threshold. The first temperature difference can characterize the temperature difference between the current cooling water temperature and the first threshold. In the case where the cooling water temperature is greater than the first control threshold, the greater the first temperature difference, the greater the power of the first cooling system is usually required to cool down as quickly as possible. In the case where the first temperature difference becomes smaller, the power of the first cooling system can be reduced. Therefore, some embodiments provided by the present invention can dynamically and in real time adjust the power of the first cooling system according to the first temperature difference while meeting the cooling and temperature reduction requirements, and can reduce or eliminate the need to operate the cooling system at rated / specified power, thereby reducing resource consumption for power adjustment of the cooling system.

[0056] S36: When the cooling water temperature is greater than the second control threshold, the power of the first cooling system is adjusted according to the first temperature difference, and the power of the second cooling system in the cooling system is adjusted according to the second temperature difference, and the second temperature difference is determined based on the cooling water temperature and the second control threshold.

[0057] When the cooling water temperature is greater than the second control threshold, the cooling water temperature is usually high at this time, and the first cooling system and the second cooling system can be started to cool down. The power adjustment when starting the first cooling system can refer to the above-mentioned processing method according to the first temperature difference. The power adjustment when starting the second cooling system can refer to the above-mentioned processing method of adjusting the first cooling system according to the first temperature difference, and the power of the second cooling system can be adjusted according to the second temperature difference.

[0058] In some embodiments of the present invention, the specific implementation of adjusting the power of the first cooling system or the power of the second cooling system can be implemented according to the specific structure and / or control strategy of the cooling system. Figure 1 In a water cooling system, the speed of the water pump motor in the water cooling system can be dynamically adjusted according to the first temperature difference to adjust the power of the water cooling system. In a refrigerant cooling system, the pressure value of the refrigerant cooling circuit can be adjusted by dynamically adjusting the low / high pressure switch according to the second temperature difference, thereby adjusting the power of the refrigerant cooling system.

[0059] The vehicle cooling system power control method provided by the present invention can provide at least two cooling systems, and perform corresponding cooling system power control according to the real-time cooling water temperature in different temperature ranges. Compared with the solution of using the rated power of a single cooling system for cooling in the related art, the operation strategies of different cooling systems can be dynamically adjusted while meeting the cooling demand, which can effectively reduce energy consumption. In the implementation scheme provided by the present invention, the power of the cooling system can be adjusted according to the first temperature difference and / or the second temperature difference corresponding to the cooling water temperature and the first control threshold and / or the second control threshold. The cooling water temperature of the present invention is an optimized parameter value further determined according to the inlet water temperature and the outlet water temperature, so that the power adjustment of the cooling system is more accurate and reasonable, and is more suitable for the power adjustment of the cooling system under multiple cooling systems. It not only meets the automatic control requirements of vehicle driving heat dissipation, achieves better heat dissipation effect, and prolongs the service life of the heat dissipation device, but also can significantly reduce the power consumption of the overall cooling system and reduce resource waste.

[0060] The temperature of cooling water before and after it flows through the cooling water heat dissipation device is usually quite different, and the cooling water temperature is closely related to the control of the cooling system power. The above describes that the cooling water temperature in some embodiments of the present invention can be determined based on the inlet water temperature and the outlet water temperature. In some other embodiments provided by the present invention, a weight factor can be provided, and the weight factor is used to perform weighted processing on at least one of the outlet water temperature and the inlet water temperature to obtain a more accurate cooling water temperature. Figure 4 FIG. 1 is a flow chart showing a method for controlling power of a cooling system of a vehicle according to an exemplary embodiment. Figure 4 As shown, the cooling water temperature is determined based on the monitored inlet water temperature and outlet water temperature, including:

[0061] S302: Determine the cooling water temperature based on the inlet water temperature, the outlet water temperature, and a weight factor, where the weight factor is used to perform weighted processing on at least one of the inlet water temperature and the outlet water temperature.

[0062] The weight factor can be determined according to the type of cooling system, the structure of the cooling system, the structure of the heat sink itself / the heat sink included, other cooling parameters, etc., or the weight factor can be determined after simulation based on at least one of the above data information. The weight factor can be a specific value or a value range. One of the purposes of weighted processing using the weight factor is to obtain cooling water temperature data that is more in line with the current scenario, so that the subsequent results of cooling system power adjustment based on cooling water temperature are more accurate and reliable. When determining the cooling water temperature using the weight factor, the value of the weight factor can also be adjusted according to the environment / parameter changes, multiple cooling water temperature determinations, and other scenarios. For example, in the case where the cooling water temperature is between the first control threshold and the second control threshold, the weight factor can take different values ​​from the case where the cooling water temperature is greater than the second control threshold, or the weight factor values ​​when starting the first cooling system and starting the second cooling system for power adjustment are different, or the weight factor values ​​when the cooling system is adjusted for power once and the next time the cooling system is adjusted for power can be different.

[0063] The weight factor can be used to weight the inlet water temperature, the outlet water temperature, or both. For example, in some examples, a can be set as the weight factor, Tavg as the cooling water temperature, Tin as the inlet water temperature, and Tout as the outlet water temperature. The following settings can be defined:

[0064] Cooling water temperature Tavg=Tin+(1-a)*Tout.

[0065] Of course, in other embodiments, the weight value factor may be used to weight the inlet water temperature, or two weight factors may be set to weight the outlet water temperature and the inlet water temperature respectively to obtain the cooling water temperature.

[0066] Some embodiments provided by the present invention use weight factors to perform weighted processing on at least one of the outlet water temperature and the inlet temperature, so as to obtain a cooling water temperature that is more in line with the current scenario, so that the subsequent cooling system power adjustment based on the cooling water temperature is more accurate and reliable.

[0067] As can be seen from the foregoing description, the temperature of cooling water at different positions in the cooling system is usually different, so the temperature data measured by sensors at different positions are also usually different. In some other implementations provided by the present invention, the weight factor can also be determined based on the path length of the water inlet temperature sensor and the water outlet temperature sensor from the heat sink. In this way, determining the weight factor based on the path distance between the temperature sensor and the radiator can make the obtained weight factor more accurate, and thus obtain a more accurate cooling water temperature. Specifically, in some other embodiments provided by the present invention, the weight factor is determined based on at least a first path between the water inlet temperature sensor for monitoring the inlet water temperature and the heat sink, and a second path between the water outlet temperature sensor for monitoring the outlet water temperature and the heat sink.

[0068] For example Figure 5 As shown, in some embodiments of the present invention, the first path may generally refer to the path of the cooling water from the position of the water inlet temperature sensor to the position of the heat sink in the direction in which the cooling water enters the radiator along the cooling water circulation pipeline, such as Figure 5 The second path may generally refer to the path of the cooling water from the heat sink to the outlet water temperature sensor in the direction in which the cooling water leaves the heat sink along the cooling water circulation pipeline, as shown in FIG. Figure 5 The present invention does not exclude that in some other embodiments, the first path or the second path may also use the straight-line distance between the corresponding temperature sensor and the heat sink, or the path distance or straight-line distance between a specific heat sink in the heat sink.

[0069] In some embodiments of the present invention, determining the weight factor based on the first path and the second path may include determining the value of the weight factor, such as the value of the weight factor a determined when using the Tavg=Tin+(1-a)*Tout method is 0.3, and may include adjusting the currently determined weight factor based on the first path and / or the second path, such as the weight factor determined when Tavg=Tin+(1-a)*Tout is 0.3. Since the water outlet temperature sensor is far away from the heat sink, the second path value is relatively large. At this time, the measured water outlet temperature is lower than the temperature at the water outlet of the heat sink. Therefore, the weight factor can be corrected by using the correspondence between the pre-set weight factor and the path length, such as compensating the weight factor a by -0.02, and the weight factor obtained at this time is 0.28.

[0070] In some embodiments of the cooling system power control method for vehicles provided by the present invention, the distance between the temperature sensor and the heat sink is taken into consideration, and a more accurate weight factor is determined based on this, thereby obtaining a more accurate cooling water temperature, thereby making the cooling system power adjustment based on the cooling water temperature more accurate.

[0071] In some embodiments of the present invention, when adjusting the power of the corresponding cooling system according to the first temperature difference or the second temperature difference, the target power to be adjusted can be determined, and the control device or application parameter in the cooling system can be adjusted accordingly. For example, according to the first temperature difference, it is determined to adjust the power of the water cooling system to P. In actual applications, the water cooling system is cooled and adjusted by adjusting the speed of the water pump motor, so the speed of the water pump motor can be adjusted to the speed corresponding to P. In some other embodiments of the present invention, the power adjustment of the cooling system can also include adjusting the speed of increasing or decreasing the power of the cooling system. Specifically, in some other embodiments of the method, the adjusting the power of the first cooling system according to the first temperature difference includes: adjusting the speed of increasing or decreasing the power of the first cooling system according to the first temperature difference, and / or, the adjusting the power of the second cooling system in the cooling system according to the second temperature difference includes: adjusting the speed of increasing or decreasing the power of the second cooling system according to the second temperature difference.

[0072] In some application scenarios, if the cooling water temperature is slightly higher than the first control threshold, that is, the first temperature difference is small (specifically, the first temperature difference can be set to a value in a small range), a smaller cooling system power can be used for slow cooling. When the cooling water temperature is much higher than the second control threshold, that is, the second temperature difference is large (specifically, the second temperature difference can be set to a value in a large range), a larger cooling system power can be used for rapid cooling. The present invention provides a method that can be implemented in similar scenarios as described above to adjust the cooling system power in real time, dynamically, and flexibly according to the temperature difference to meet the cooling requirements in different scenarios. Specifically, the speed at which the power of the first cooling system increases or decreases can be adjusted according to the first temperature difference, and / or the speed at which the power of the second cooling system increases or decreases can be adjusted according to the second temperature difference. The speed at which the power of the first or second cooling system increases or decreases can include the speed at which the power of the first or second cooling system increases accordingly with the speed at which the current temperature increases. For example, each sub-cooling system may be provided with one or more adjustment parameters, which may be associated with the temperature difference between the cooling water and the corresponding first or second control threshold value. When the adjustment parameter is adjusted, the speed at which the power of the corresponding sub-cooling system increases or decreases may be adjusted accordingly, thereby achieving that when the temperature increases rapidly, the power of the cooling system is dynamically adjusted to increase rapidly, thereby effectively achieving rapid cooling; and when the temperature increases slowly, the power increase of the cooling system may be adjusted to slow down accordingly, thereby saving the power consumption of the cooling system and reducing energy waste.

[0073] The selection or device of the adjustment parameter can select one or more dynamic functions involved in the temperature field according to the control requirements, etc. f can be set as the dynamic function of the water cooling system power adjustment, and its expression can be:

[0074] (Formula 1);

[0075] g can be set as a dynamic function of the refrigerant cooling system power adjustment, and its expression can be:

[0076] (Formula 2);

[0077] In the above formulas 1 and 2, Tavg can be expressed as the cooling water temperature, T1 can be expressed as the first control threshold, T2 can be expressed as the second control threshold, e is a natural number constant, a and b are adjustment parameters in the water cooling system, which can be used to control the water cooling system to increase or decrease the power adjustment speed as the temperature difference changes, c and d are adjustment parameters in the refrigerant cooling system, which can be used to control the refrigerant cooling system to increase or decrease the power adjustment speed as the temperature difference changes, T is expressed as the temperature of the cooling water at the current moment, which can be the average value of the cooling water temperature at different positions, or other algorithms or methods can be used to obtain the cooling water temperature T at the current moment.

[0078] Figure 6 FIG. 1 is a flow chart showing a method for controlling power of a cooling system of a vehicle according to an exemplary embodiment. Figure 6 As shown (the dotted arrow indicates an optional implementation scheme), in some other embodiments of the method, before adjusting the power of the first cooling system and / or adjusting the power of the second cooling system, the method further includes:

[0079] S60: When the cooling constraint condition is met, mutually exclusive adjusting the power adjustment parameters of the first cooling system and the second cooling system in a simulation manner, and determining at least one total expected power corresponding to the power adjustment parameters after the power adjustment parameters are adjusted, wherein the total expected power includes the sum of the power of the first cooling system and the power of the second cooling system after the power adjustment parameters are adjusted, and the mutually exclusive adjustment includes that when the power of one cooling system is increased / decreased, the power of the other cooling system is decreased / increased;

[0080] S62: determining a target total expected power from the total expected power, the target total expected power comprising a total expected power decreased compared to a current total power of the first cooling system and the second cooling system before the power condition parameter is adjusted;

[0081] The method of adjusting the power of the first cooling system according to the first temperature difference and / or adjusting the second cooling system according to the second temperature difference includes adjusting the first cooling system according to the power adjustment parameters of the first cooling system corresponding to the target total expected power and / or adjusting the second cooling system according to the power adjustment parameters of the second cooling system corresponding to the target total expected power.

[0082] The cooling constraint conditions may include basic conditions that the cooling system meets during operation, which are determined in advance based on one or more factors such as the vehicle cooling system structure, the use environment, and the cooling and cooling requirements. For example, the cooling constraint conditions may include the minimum / maximum operating power, operating time, etc. of each cooling system or sub-cooling system in the cooling system, and may also include related constraints determined based on the cooling time to reduce the cooling water temperature to below the target temperature. The simulation method may include using simulation applications or data, graphs, tables, etc. to simulate the operating state of the cooling system under different parameters. The mutually exclusive adjustment usually refers to the case where multiple cooling systems are involved. If the power of one cooling system is increased by adjusting the power parameters, then the power of at least one cooling system other than the cooling system with the increased power currently adjusted is adjusted to decrease; correspondingly, if the power of one cooling system increases, the power of at least one cooling system is also reduced.

[0083] In some embodiments provided by the present invention, before actually adjusting the power of the cooling system, the power adjustment parameters of each cooling system can be simulated and adjusted respectively, and simulated adjustments can be performed. During the period of adjusting the power increase or decrease of one cooling system, the power of another cooling system can be adjusted to perform the opposite power reduction or increase. In this way, while ensuring the heat dissipation demand and satisfying the cooling constraints, the power adjustment parameters of different cooling systems are simulated and adjusted respectively, and then the total expected power after simulation is compared to see whether there is a decreased total expected power. If so, one of the decreased total expected powers can be selected as the target expected total power for adjustment, and then the power adjustment parameters of the corresponding cooling system can be actually adjusted according to the target expected total power.

[0084] For example, in one example, it is determined according to the parameters of the current cooling system or other methods that the power of the first cooling system needs to be adjusted to P1, and the power of the second cooling system needs to be adjusted to P2. It can be pre-calculated inside the processor that if the power adjustment parameters of the first cooling system are adjusted to increase its power value, P11 is obtained, and at the same time, the power adjustment parameters of the second cooling system are adjusted to decrease its power value to obtain P21. The total expected power (P11+P21) after the power adjustment parameters are adjusted once can be obtained. Of course, multiple power adjustment parameters can also be adjusted in other implementations to obtain multiple total expected powers. After the power adjustment parameters are adjusted, the state or parameters of the cooling system still meet the cooling constraint conditions, then the total expected power can be compared with the current total power before the power adjustment parameters are adjusted. If the total expected power decreases compared to the current total power, it can be characterized that the overall power of the cooling system after the power parameter adjustment can be further reduced, and the total expected power can be used as the target total expected power. In the actual power adjustment process, the power adjustment parameters of each cooling system can be adjusted respectively according to the target total expected power, thereby further reducing the overall power consumption of the cooling system.

[0085] In other embodiments, multiple power regulation parameter adjustments are performed to obtain multiple total expected powers. For example, a simulation calculation duration value may be set, and the power regulation parameters may be adjusted within the simulation calculation duration value to obtain one or more total expected powers. Alternatively, a simulation calculation number of total expected powers may be set, and the adjustment of the power regulation parameters of the cooling system may be stopped when the number of total expected powers obtained by simulation reaches the simulation calculation number. Of course, the above two methods or other reference quantities may also be combined to obtain the total expected power under at least one of the conditions. In this way, by using the simulation calculation duration value and / or the simulation calculation number of values, the power adjustment of the cooling system may be performed in a timely manner to meet the cooling demand, and the total expected power with the smallest total expected power may be selected as the target total expected power when multiple total expected powers are obtained, so as to achieve power control of the cooling system tending to the minimum power consumption, and further reduce the energy consumption of the cooling system.

[0086] The present invention provides some cooling system power control methods that adopt simulation to mutually exclusively adjust different sets of cooling systems. Before actually adjusting the cooling system power, a target total expected power of the sum of the powers of each cooling system can be obtained by pre-simulating and calculating, and then the parameters of each cooling system can be actually adjusted according to the target total expected power. This can further reduce the power consumption of the entire cooling system, ensure that the cooling needs are met, and at the same time more intelligently and automatically control the power adjustment of each cooling system, thereby further saving energy consumption.
