Description

Technical Field

[0001] This application relates to the field of compressor control technology, and in particular to a compressor restart frequency control method, device and computer-readable storage medium. Background Technology

[0002] Currently, air conditioners and other similar devices typically shut down their internal compressors after reaching or exceeding the set temperature. When the compressor is restarted, it usually starts running at the rated operating frequency, which leads to frequent compressor shutdowns. This results in significant temperature fluctuations and recurring abnormal noises, affecting the user experience.

[0003] Therefore, how to avoid frequent compressor shutdowns in order to improve the user experience is an urgent problem that needs to be solved. Summary of the Invention

[0004] The main objective of this application is to provide a method, device, and computer-readable storage medium for controlling the restart frequency of a compressor, which aims to avoid frequent compressor shutdowns and improve the user experience.

[0005] To achieve the above objectives, this application provides a compressor restart frequency control method, the compressor restart frequency control method comprising:

[0006] When the target device is controlled to operate according to the set conditions, if the compressor of the target device is detected to stop, the first operating frequency of the compressor at the moment before the stop is obtained.

[0007] When the compressor restarts, the total running time of the target device under the set conditions and the cumulative downtime of the compressor under the set conditions are obtained.

[0008] The target operating frequency is determined based on the total operating time, the cumulative downtime, the first operating frequency, and the rated operating frequency of the compressor; the target operating frequency is less than the rated operating frequency.

[0009] After the compressor is restarted, it operates at the target operating frequency.

[0010] In one embodiment, the step of determining the target operating frequency based on the total runtime, the cumulative downtime, the first operating frequency, and the compressor's rated operating frequency includes:

[0011] The cumulative number of times the compressor stops under the set conditions is obtained, and the ratio of the cumulative stop time to the total running time is calculated to obtain the first weight of the first operating frequency;

[0012] A second weight for the rated operating frequency is determined based on the cumulative number of downtimes and the first weight; the second weight is less than the first weight.

[0013] The target operating frequency is obtained by performing a weighted average calculation on the first operating frequency and the rated operating frequency based on the first weight and the second weight.

[0014] In one embodiment, the step of determining the second weight of the rated operating frequency based on the cumulative number of downtimes and the first weight includes:

[0015] Add one to the cumulative number of downtimes to obtain the first target exponent;

[0016] Calculate the first target exponent power of the first weight to obtain the second weight of the rated operating frequency;

[0017] Alternatively, the first target reduction ratio can be obtained by multiplying the cumulative number of downtimes by the preset initial reduction ratio.

[0018] The second weight of the rated operating frequency is calculated based on the first target reduction ratio and the first weight.

[0019] In one embodiment, the step of determining the target operating frequency based on the total runtime, the cumulative downtime, the first operating frequency, and the compressor's rated operating frequency includes:

[0020] Obtain the second operating frequency of the compressor at the moment before shutdown in each historical shutdown stage under the set conditions;

[0021] The target operating frequency is determined based on the total operating time, the cumulative downtime, the first operating frequency, each of the second operating frequencies, and the rated operating frequency.

[0022] In one embodiment, the step of determining the target operating frequency based on the total runtime, the cumulative downtime, the first operating frequency, each of the second operating frequencies, and the rated operating frequency includes:

[0023] Calculate the ratio of the cumulative downtime to the total running time to obtain the first weight of the first operating frequency;

[0024] Count the number of each of the second operating frequencies, and add one to the count to obtain the target number;

[0025] By repeatedly reducing the first weight, the candidate weights for the target number are obtained;

[0026] The minimum value among the candidate weights is taken as the second weight of the rated operating frequency, and a third weight of each second operating frequency is determined from the remaining candidate weights based on the shutdown time corresponding to each second operating frequency; wherein, the third weight of the second operating frequency is positively correlated with the shutdown time corresponding to the second operating frequency.

[0027] The target operating frequency is obtained by performing a weighted average calculation on the first operating frequency, the rated operating frequency, and each of the third weights based on the first weight, the second weight, and each of the third weights.

[0028] In one embodiment, the step of repeatedly reducing the first weight to obtain the target number of candidate weights includes:

[0029] By gradually increasing the exponent of the first weight or decreasing the ratio, a second target exponent or a second target reduction ratio is obtained for the target quantity.

[0030] The first weight is reduced according to the exponent of each second target or the reduction ratio of each second target, to obtain the candidate weights for the number of targets.

[0031] In one embodiment, the compressor restart frequency control method further includes:

[0032] If a change in the set conditions is detected, the target device is controlled to operate according to the changed set conditions.

[0033] In one embodiment, the setting conditions include setting an operating mode and / or setting a temperature.

[0034] In addition, to achieve the above objectives, this application also provides a compressor restart frequency control device, which includes a memory, a processor, and a compressor restart frequency control program stored in the memory and executable on the processor. When the automatic control program is executed by the processor, it implements the steps of the compressor restart frequency control method described above.

[0035] In addition, to achieve the above objectives, this application also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the compressor restart frequency control method described above.

[0036] In addition, to achieve the above objectives, this application also provides a computer program product, including a computer program that, when executed by a processor, implements the steps of the compressor restart frequency control method described above.

[0037] This application provides a compressor restart frequency control method. When the target equipment is controlled to operate according to set conditions, if the compressor of the target equipment is detected to be shut down, the first operating frequency of the compressor at the moment before the shutdown is obtained. When the compressor restarts, the total running time of the target equipment under the set conditions and the cumulative shutdown time of the compressor under the set conditions are obtained. Based on the total running time, the cumulative shutdown time, the first operating frequency and the rated operating frequency of the compressor, the target operating frequency is determined. The target operating frequency is less than the rated operating frequency. After the compressor restarts, it is controlled to operate at the target operating frequency.

[0038] Therefore, when the compressor stops and restarts, this application can determine the target operating frequency after restarting the compressor based on the first operating frequency at the moment before the compressor stops, the total running time of the target equipment, the cumulative downtime of the compressor, and the rated operating frequency of the compressor. Since the target operating frequency is less than the rated operating frequency, the compressor can reach the temperature more slowly by operating at the target operating frequency after restarting compared to operating at the rated operating frequency, thereby extending the running time of the compressor after restarting. This reduces the frequency of compressor shutdowns, thereby avoiding frequent compressor shutdowns and improving the user experience. Attached Figure Description

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0048] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0049] Currently, air conditioners and other similar devices typically shut down their internal compressors after reaching or exceeding the set temperature. When the compressor is restarted, it usually starts running at the rated operating frequency, which leads to frequent compressor shutdowns. This results in significant temperature fluctuations and recurring abnormal noises, affecting the user experience.

[0050] Therefore, how to avoid frequent compressor shutdowns in order to improve the user experience is an urgent problem that needs to be solved.

[0051] This application provides a compressor restart frequency control method. When the target equipment is controlled to operate according to set conditions, if the compressor of the target equipment is detected to be shut down, the first operating frequency of the compressor at the moment before the shutdown is obtained. When the compressor restarts, the total running time of the target equipment under the set conditions and the cumulative shutdown time of the compressor under the set conditions are obtained. Based on the total running time, the cumulative shutdown time, the first operating frequency and the rated operating frequency of the compressor, the target operating frequency is determined. The target operating frequency is less than the rated operating frequency. After the compressor restarts, it is controlled to operate at the target operating frequency.

[0052] Therefore, when the compressor stops and restarts, this application can determine the target operating frequency after restarting the compressor based on the first operating frequency at the moment before the compressor stops, the total running time of the target equipment, the cumulative downtime of the compressor, and the rated operating frequency of the compressor. Since the target operating frequency is less than the rated operating frequency, the compressor can reach the temperature more slowly by operating at the target operating frequency after restarting compared to operating at the rated operating frequency, thereby extending the running time of the compressor after restarting. This reduces the frequency of compressor shutdowns, thereby avoiding frequent compressor shutdowns and improving the user experience.

[0053] The executing entity of the compressor restart frequency control method of this application can be a compressor restart frequency control device with data processing, network communication, and program execution functions, such as an air conditioner or refrigerator, or a control system or control circuit capable of realizing the above functions. This embodiment does not specifically limit it. The following uses a compressor restart frequency control device as the executing entity to describe the following embodiments.

[0054] Based on this, this application proposes a compressor restart frequency control method according to the first embodiment, please refer to... Figure 1 The compressor restart frequency control method includes steps S10 to S40:

[0055] Step S10: When the target device is controlled to operate according to the set conditions, if the compressor of the target device is detected to stop, the first operating frequency of the compressor at the moment before the stop is obtained.

[0056] It should be noted that the target device is a device equipped with a compressor, which can be an air conditioner, refrigerator, etc., and this embodiment does not specifically limit it. The setting conditions include the operating mode and / or various operating parameters set by the user or by default by the device itself. For example, the setting conditions may include setting the operating mode and / or setting the temperature.

[0057] When obtaining the first operating frequency at the moment before the compressor stops, it can be obtained from the compressor restart frequency control device or from other devices connected to the compressor restart frequency control device. This embodiment does not specifically limit this.

[0058] Step S20: When the compressor restarts, obtain the total running time of the target device under the set conditions and the cumulative downtime of the compressor under the set conditions;

[0059] When obtaining the total running time of the target device under set conditions and the cumulative downtime of the compressor under set conditions, the information can be obtained from the compressor restart frequency control device or from other devices connected to the compressor restart frequency control device. This embodiment does not specifically limit the information in this regard.

[0060] Step S30: Determine the target operating frequency based on the total running time, the cumulative downtime, the first operating frequency, and the rated operating frequency of the compressor; the target operating frequency is less than the rated operating frequency.

[0061] It should be noted that the target operating frequency is the operating frequency required for the compressor to start up initially.

[0062] In one feasible implementation, step S30 may include: calculating the ratio of cumulative downtime to total running time to obtain a first weight of the first operating frequency; determining a second weight of the rated operating frequency based on the first weight, wherein the second weight is less than the first weight; and performing a weighted average calculation on the first operating frequency and the rated operating frequency based on the first weight and the second weight to obtain the target operating frequency.

[0063] In determining the second weight of the rated operating frequency based on the first weight, the second weight of the rated operating frequency can be determined by combining the cumulative number of compressor shutdowns under set conditions, or by using a preset power or a reduction ratio to determine the second weight of the rated operating frequency based on the first weight. This embodiment does not impose any specific limitations on this.

[0064] In another feasible implementation, in order to improve the efficiency of determining the target operating frequency, a frequency relationship table can be constructed in advance to record the total running time, cumulative downtime, operating frequency at the moment before the compressor stops, rated operating frequency, and operating frequencies that have a mapping relationship with the total running time, cumulative downtime, operating frequency at the moment before the compressor stops, and rated operating frequency. Then step S30 may include: finding the target operating frequency corresponding to the total running time, cumulative downtime, first operating frequency, and rated operating frequency of the compressor in the preset frequency relationship table.

[0065] The above are only two feasible implementation methods of step S30 provided in this embodiment. This embodiment does not specifically limit the specific implementation method of step S30.

[0066] In one feasible implementation, if the second weight of the rated operating frequency is determined based on the first weight by combining the cumulative number of compressor shutdowns under set conditions, then step S30 may include steps S31 to S33:

[0067] Step S31: Obtain the cumulative number of times the compressor stops under the set conditions, and calculate the ratio of the cumulative stop time to the total running time to obtain the first weight of the first operating frequency;

[0068] Step S32: Determine the second weight of the rated operating frequency based on the cumulative number of downtimes and the first weight; the second weight is less than the first weight.

[0069] It should be noted that in this embodiment, the weight of the first operating frequency is referred to as the first weight for distinction, and the weight of the rated operating frequency is referred to as the second weight for distinction.

[0070] In one feasible implementation, step S32 may include steps S321 to S322:

[0071] Step S321: Increment the cumulative number of shutdowns by one to obtain the first target exponent;

[0072] Step S322: Calculate the first target exponent power of the first weight to obtain the second weight of the rated operating frequency.

[0073] It should be noted that the calculation process for obtaining the second weight of the rated operating frequency by calculating the first target exponent of the first weight can be expressed as the following formula:

[0074] r2 = r1 a

[0075] Where r1 is the first weight, r2 is the second weight, and a is the first target exponent.

[0076] It is understandable that since the target equipment is still running when the compressor stops, the total running time of the target equipment under the set conditions must be greater than the cumulative downtime of the compressor under the set conditions. Therefore, the first weight must be less than 1. Thus, by calculating the first target exponent of the first weight, the result obtained must be less than the value of the first weight.

[0077] In another feasible implementation, step S32 may include steps S323 to S324:

[0078] Step S323: Calculate the product of the cumulative number of shutdowns and the preset initial reduction ratio to obtain the first target reduction ratio;

[0079] Step S324: Calculate the second weight of the rated operating frequency based on the first target reduction ratio and the first weight.

[0080] The above are only two feasible implementation methods of step S32 provided in this embodiment. This embodiment does not specifically limit the specific implementation method of step S32.

[0081] It is understandable that the two feasible implementations of the two steps S32 provided above can gradually reduce the second weight of the rated operating frequency as the cumulative number of shutdowns gradually increases. This allows the subsequently determined target operating frequency to tilt more towards the operating frequency at the moment before the compressor stops, thereby further reducing the frequency of compressor shutdowns. This can better avoid frequent compressor shutdowns and thus improve the user experience.

[0082] Step S33: Based on the first weight and the second weight, perform a weighted average calculation on the first operating frequency and the rated operating frequency to obtain the target operating frequency.

[0083] It should be noted that the calculation process for obtaining the target operating frequency by weighted averaging of the first operating frequency and the rated operating frequency based on the first weight and the second weight can be expressed as the following formula:

[0084]

[0085] Where Pi is the target operating frequency, P1 is the first operating frequency, P0 is the rated operating frequency, r1 is the first weight, and r2 is the second weight.

[0086] Step S40: Control the compressor to restart and then operate at the target operating frequency.

[0087] In this embodiment, when the compressor stops and restarts, the target operating frequency to be operated after restarting can be determined based on the first operating frequency of the compressor at the moment before the compressor stops, the total running time of the target equipment, the cumulative downtime of the compressor, and the rated operating frequency of the compressor. Since the target operating frequency is less than the rated operating frequency, the compressor can reach the temperature more slowly after restarting by operating at the target operating frequency compared to operating at the rated operating frequency. This extends the running time of the compressor after restarting, thereby reducing the frequency of compressor shutdowns and thus avoiding frequent compressor shutdowns, improving the user experience.

[0088] Furthermore, since frequent compressor shutdowns increase the power consumption of the target device, this embodiment can effectively reduce the power consumption of the target device by avoiding frequent compressor shutdowns.

[0089] For example, please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram illustrating the improved operating process where the compressor continues to operate at its rated frequency (50Hz) after a shutdown and restart. Figure 3 This is a schematic diagram illustrating the operating process of the improved compressor after shutdown and restart, starting at the newly determined target operating frequency (40Hz). Figure 2 and Figure 3 It can be seen that the overall operating frequency of the improved compressor after shutdown and restart is lower than that of the unimproved compressor after shutdown and restart. As a result, it can reach the temperature more slowly, thereby extending the running time of the compressor after restarting. This reduces the frequency of compressor shutdown, thus avoiding frequent compressor shutdowns and improving the user experience.

[0090] Based on the first embodiment described above, a second embodiment of the compressor restart frequency control method of this application is proposed. For the second embodiment, please refer to... Figure 4 Step S30 may include steps A10 to A20:

[0091] Step A10: Obtain the second operating frequency of the compressor at the moment before shutdown in each historical shutdown stage under the set conditions;

[0092] It should be noted that the historical shutdown phase refers to the period from the starting time when the target equipment began to operate according to the set conditions to the current time, excluding the current shutdown phase experienced by the compressor.

[0093] When obtaining the second operating frequency of the compressor at the moment before shutdown in each historical shutdown stage under the set conditions, it can be obtained from the compressor restart frequency control device or from other devices connected to the compressor restart frequency control device. This embodiment does not specifically limit this.

[0094] Step A20: Determine the target operating frequency based on the total running time, the cumulative downtime, the first operating frequency, each of the second operating frequencies, and the rated operating frequency.

[0095] This embodiment can also combine the second operating frequency of the compressor at the moment before shutdown in each historical shutdown stage under set conditions to determine the target operating frequency. This makes the determined target operating frequency more inclined to the operating frequency at the moment before the compressor shutdown compared to the target operating frequency determined in the first embodiment above, so as to further reduce the frequency of compressor shutdown, thereby better avoiding frequent compressor shutdown and thus improving the user experience.

[0096] In one feasible implementation, step A20 may include: calculating the ratio of cumulative downtime to total operating time to obtain a first weight of the first operating frequency; counting the number of each second operating frequency and adding one to the counted number to obtain a target number; determining a second weight of the rated operating frequency and a third weight of each second operating frequency based on the first weight, the target number, and the downtime corresponding to each second operating frequency, wherein the second weight is less than the first weight and less than each third weight, and the third weight of the second operating frequency is positively correlated with the downtime corresponding to the second operating frequency; and calculating a weighted average of the first operating frequency, the rated operating frequency, and each second operating frequency based on the first weight, the second weight, and each third weight to obtain the target operating frequency.

[0097] In determining the second weight of the rated operating frequency and the third weight of each second operating frequency based on the first weight, the target quantity, and the shutdown time corresponding to each second operating frequency, the candidate weights of the target quantity can be obtained by regularly decreasing the first weight, or by irregularly decreasing the first weight. Then, the second weight of the rated operating frequency and the third weight of each second operating frequency are determined from the candidate weights. This embodiment does not make specific limitations on this.

[0098] In another feasible implementation, to improve the efficiency of determining the target operating frequency, a frequency relationship table can be pre-constructed to record the total operating time, cumulative downtime, operating frequency of the compressor at the moment before shutdown, operating frequency of the compressor at the moment before shutdown in each historical shutdown stage, rated operating frequency, and operating frequencies that have a mapping relationship with the total operating time, cumulative downtime, operating frequency of the compressor at the moment before shutdown in each historical shutdown stage, and rated operating frequency. Then step A20 may include: finding the target operating frequency corresponding to the total operating time, cumulative downtime, first operating frequency, each second operating frequency, and rated operating frequency of the compressor in the preset frequency relationship table.

[0099] The above are only two feasible implementations of step A20 provided in this embodiment. This embodiment does not specifically limit the specific implementation of step A20.

[0100] In one feasible implementation, step A20 may include steps A21 to A25:

[0101] Step A21: Calculate the ratio of the cumulative downtime to the total running time to obtain the first weight of the first operating frequency;

[0102] Step A22: Count the number of each of the second operating frequencies, and add one to the counted number to obtain the target number;

[0103] Step A23: Decrease the first weight multiple times to obtain the candidate weights for the target number;

[0104] In one feasible implementation, step A23 may include steps A231 to A232:

[0105] Step A231: By gradually increasing the exponent of the first weight or decreasing the ratio, the second target exponent or the second target reduction ratio of the target quantity is obtained.

[0106] When gradually increasing the exponent of the first weight or decreasing the percentage, it essentially means gradually increasing the exponent of the first weight or decreasing the percentage based on the initial value of the exponent of the first weight or the initial value of the percentage decrease. The initial value of the exponent of the first weight or the initial value of the percentage decrease can be set by the user.

[0107] When gradually increasing or decreasing the power of the first weight, the power of the first weight can be increased or decreased by the default increment, or the increment can be flexibly adjusted according to the actual operating conditions of the compressor or target equipment, and then the power of the first weight can be increased or decreased by the adjusted increment. This embodiment does not make specific limitations on this.

[0108] Step A232: Reduce the first weight according to each of the second target exponents or each of the second target reduction ratios to obtain the candidate weights for the number of targets.

[0109] This implementation method gradually increases the exponent of the first weight or decreases the percentage to achieve a regular reduction of the first weight. This ensures that as the number of second operating frequencies gradually increases, that is, as the cumulative number of compressor shutdowns under set conditions gradually increases, the operating frequency required for the initial restart of the compressor will also gradually decrease. This steadily reduces the compressor shutdown frequency, thereby better avoiding frequent compressor shutdowns and improving the user experience.

[0110] Step A24: The minimum value among the candidate weights is taken as the second weight of the rated operating frequency, and the third weight of each second operating frequency is determined from the remaining candidate weights based on the shutdown time corresponding to each second operating frequency; wherein, the third weight of the second operating frequency is positively correlated with the shutdown time corresponding to the second operating frequency.

[0111] It should be noted that in this embodiment, the weight of the second operating frequency is referred to as the third weight to distinguish it.

[0112] Step A25: Based on the first weight, the second weight, and each of the third weights, perform a weighted average calculation on the first operating frequency, the rated operating frequency, and each of the second operating frequencies to obtain the target operating frequency.

[0113] It is understandable that the more second operating frequencies there are, the smaller the second weight of the rated operating frequency will be. Therefore, as the number of second operating frequencies gradually increases, that is, as the cumulative number of compressor shutdowns under the set conditions gradually increases, the second weight of the rated operating frequency gradually decreases. This allows the subsequently determined target operating frequency to lean more towards the operating frequency at the moment before the compressor shutdown, thereby further reducing the frequency of compressor shutdowns and thus better avoiding frequent compressor shutdowns, thereby improving the user experience.

[0114] Based on the first and / or second embodiments described above, a third embodiment of the compressor restart frequency control method of this application is proposed. In the third embodiment, the compressor restart frequency control method further includes step S50:

[0115] Step S50: If a change in the set conditions is detected, control the target device to operate according to the changed set conditions.

[0116] Understandably, if the monitoring settings change, the target device needs to be controlled to operate according to the changed settings. When the target device operates according to the changed settings, the shutdown triggering conditions of its internal compressor will also change. Therefore, it is necessary to re-record data such as the total running time of the target device, the cumulative shutdown time of the compressor, the cumulative number of shutdowns, and the operating frequency of the compressor at the moment before shutdown under the changed settings. In this way, the operating frequency required for the initial restart of the compressor under different settings can be flexibly adjusted to effectively avoid frequent shutdowns of the compressor under different settings.

[0117] This application also provides a compressor restart frequency control device, which includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to execute the compressor restart frequency control method in the above embodiments.
