Description

Technical Field

[0001] This application belongs to the field of storage equipment, and particularly relates to a control method, device and storage equipment for a storage device. Background Technology

[0002] To prevent ice buildup on the condenser and evaporator surfaces of storage devices, these devices typically require periodic defrosting. While some technologies involve controlling the defrosting process via a main control board when the evaporator temperature falls below a set threshold, this method is susceptible to failure if the main control unit malfunctions, resulting in abnormal defrosting or no defrosting at all. This limited applicability and poor user experience contribute to the problem. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a control method, device, and storage device for storage equipment, which broadens the applicable scenarios and avoids the situation where the storage equipment defrosts abnormally or fails to perform defrosting operations when the main control device malfunctions. It ensures that the storage equipment can perform defrosting operations normally even when the communication status is abnormal, thereby improving the user experience.

[0004] In a first aspect, this application provides a control method for a storage device, the method comprising:

[0005] The actual temperature of the target compartment in the storage device and the communication status between the main control device and the frequency converter in the storage device are obtained.

[0006] If the communication status is confirmed to be normal, the storage device is controlled to perform a defrosting operation based on the actual temperature.

[0007] If the communication status is determined to be abnormal, the storage device is controlled to perform a defrosting operation based on the target runtime corresponding to the compressor in the storage device; the target runtime is the sum of the first continuous runtime of the compressor before the communication status is abnormal and the second continuous runtime of the compressor after the communication status is abnormal.

[0008] According to the control method for storage equipment provided in the embodiments of this application, by judging the communication status between the main control device and the frequency converter, and performing defrosting operations in different ways under different communication statuses, the applicable scenarios are broadened; when it is determined that the communication status is abnormal, the storage equipment is controlled to perform defrosting operations based on the target runtime of the compressor, which avoids the situation where the storage equipment defrosts abnormally or does not perform defrosting operations when the main control device fails, ensuring that the storage equipment can perform defrosting operations normally even when the communication status is abnormal, thus improving the user experience.

[0009] One embodiment of the control method for a storage device according to this application includes controlling the storage device to perform a defrosting operation based on a target runtime corresponding to the compressor in the storage device, comprising:

[0010] If the target runtime is not greater than a first runtime threshold, the compressor is controlled to run at a first speed.

[0011] If the target runtime exceeds the first duration threshold, the compressor is controlled to stop rotating, and the storage device is controlled to perform a defrosting operation.

[0012] One embodiment of the control method for a storage device according to this application, after controlling the storage device to perform a defrosting operation based on the target runtime corresponding to the compressor in the storage device, the method further includes:

[0013] If the communication status is determined to be abnormal and the continuous defrosting duration of the storage device is greater than the second duration threshold, the storage device is controlled to exit the defrosting operation, and the compressor is controlled to run at the first speed after the second duration.

[0014] One embodiment of the control method for a storage device according to this application includes controlling the storage device to perform a defrosting operation based on a target runtime corresponding to the compressor in the storage device when it is determined that the communication status is abnormal.

[0015] During the defrosting operation of the storage device, if the communication status is determined to return to normal from abnormal and a defrosting command is received from the main control device, the storage device is controlled to stop the defrosting operation, and the load is controlled to stop for a third duration.

[0016] The storage device is controlled to perform a defrosting operation based on the newly acquired actual temperature of the target compartment.

[0017] One embodiment of the control method for a storage device according to this application includes controlling the storage device to perform a defrosting operation based on a target runtime corresponding to the compressor in the storage device when it is determined that the communication status is abnormal.

[0018] During the defrosting operation of the storage device, if the communication status is determined to have returned to normal from abnormal and no defrosting command is received from the main control device, the storage device is controlled to perform the defrosting operation based on the newly acquired actual temperature of the target compartment.

[0019] One embodiment of this application provides a control method for a storage device, which acquires the communication status between the main control device and the frequency converter in the storage device, including:

[0020] If the connection request information is received again within a fourth time period since the last time the main control device sent the connection request information, the communication status is determined to be normal.

[0021] If no connection request is received again within the fourth time period since the last reception of the connection request, the communication status is determined to be abnormal.

[0022] Secondly, this application provides a control device for a storage device, comprising:

[0023] The first processing module is used to obtain the actual temperature of the target compartment in the storage device and the communication status between the main control device and the frequency converter in the storage device.

[0024] The second processing module is used to control the storage device to perform a defrosting operation based on the actual temperature, provided that the communication status is normal.

[0025] The third processing module is used to control the storage device to perform a defrosting operation based on the target runtime corresponding to the compressor in the storage device when the communication status is determined to be abnormal; the target runtime is the sum of the first continuous runtime of the compressor before the communication status is abnormal and the second continuous runtime of the compressor after the communication status is abnormal.

[0026] The control device for storage equipment provided in the embodiments of this application expands the applicable scenarios by judging the communication status between the main control device and the frequency converter and performing defrosting operations in different ways under different communication statuses. When it is determined that the communication status is abnormal, the storage equipment is controlled to perform defrosting operations based on the target runtime of the compressor. This avoids the situation where the storage equipment defrosts abnormally or does not perform defrosting operations when the main control device fails, ensuring that the storage equipment can perform defrosting operations normally even when the communication status is abnormal, thus improving the user experience.

[0027] Thirdly, this application provides a storage device, comprising:

[0028] Box;

[0029] The main control device is located in the enclosure;

[0030] A frequency converter is installed in the enclosure and is communicatively connected to the main control device.

[0031] A compressor is disposed in the housing and is electrically connected to the frequency converter. The compressor rotates based on the control method of the storage device as described in the first aspect.

[0032] The storage device provided in the embodiments of this application expands the applicable scenarios by judging the communication status between the main control device and the frequency converter and performing defrosting operations in different ways under different communication statuses. When it is determined that the communication status is abnormal, the storage device is controlled to perform defrosting operations based on the target runtime of the compressor. This avoids the situation where the storage device defrosts abnormally or does not perform defrosting operations when the main control device fails, ensuring that the storage device can perform defrosting operations normally even when the communication status is abnormal, thus improving the user experience.

[0033] One embodiment of the storage device of this application further includes:

[0034] A heating wire is disposed in the housing; the heating wire is connected to the frequency converter and is used to enable the storage device to perform a defrosting operation.

[0035] Fourthly, this application provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the control method for the storage device as described in the first aspect above.

[0036] Fifthly, this application provides a computer program product, including a computer program that, when executed by a processor, implements the control method for the storage device as described in the first aspect above.

[0037] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects:

[0038] By judging the communication status between the main control unit and the frequency converter, and performing defrosting operations in different ways under different communication statuses, the applicable scenarios are broadened. When it is determined that the communication status is abnormal, the storage equipment is controlled to perform defrosting operations based on the target runtime of the compressor. This avoids the situation where the storage equipment defrosts abnormally or does not perform defrosting operations when the main control unit fails, ensuring that the storage equipment can perform defrosting operations normally even when the communication status is abnormal, thus improving the user experience.

[0039] Furthermore, by controlling the storage device to perform defrosting operation only when the compressor's continuous running time reaches a set threshold, it is possible to determine whether defrosting is needed based on the compressor's continuous running time in the event of communication abnormalities and the inverter being unable to receive defrosting commands from the main control device. This ensures the normal defrosting process of the storage device even when communication is abnormal, thus improving the user experience.

[0040] Furthermore, if the communication status returns to normal during the defrosting process of the storage equipment, the system determines whether the frequency converter has received a defrosting command from the main control unit. If the defrosting command is received, the system exits the defrosting operation and enters the normal defrosting process, thus avoiding the storage equipment from undergoing a second defrosting in a short period of time, thereby reducing power consumption and avoiding resource waste.

[0041] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0053] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0054] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0055] The control method, control device, storage device, and readable storage medium of the storage device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0056] The control method for storage devices provided in this application embodiment can be executed by the storage device, an electronic device electrically connected to the storage device, or a functional module or entity in the storage device that can implement the control method. The control method for storage devices provided in this application embodiment will be described below with the storage device as the execution subject as an example.

[0057] It should be noted that the storage device in this embodiment can be understood as a refrigeration storage device in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. The storage devices have diverse structural forms and a wide range of applications.

[0058] like Figure 1 As shown, the control method for the storage device includes steps 110, 120 and 130.

[0059] Step 110: Obtain the actual temperature of the target compartment in the storage equipment and the communication status between the main control device and the frequency converter in the storage equipment.

[0060] In this step, the storage equipment includes multiple compartments, such as a refrigerator compartment, a freezer compartment, and a fresh food compartment.

[0061] The target compartment is the compartment among multiple compartments that requires regular defrosting. The target compartment can be a freezer compartment or a refrigerator compartment.

[0062] Taking the freezer compartment as an example, under normal circumstances, the actual temperature of the freezer compartment is between -18 degrees Celsius and -23 degrees Celsius. If the actual temperature of the freezer compartment is too low, frost may form inside the freezer compartment.

[0063] Each compartment in the storage equipment can be equipped with a temperature sensor.

[0064] The actual temperature of the target compartment can be obtained based on the temperature sensor in the target compartment.

[0065] The temperature sensor can be a resistive, thermistor, or semiconductor temperature sensor, or other types of temperature sensors, which are not limited in this application.

[0066] like Figure 6 As shown, the storage equipment may include a main control device and a frequency converter.

[0067] Communication connection between the main control unit and the frequency converter.

[0068] The main control unit and the frequency converter can use a single-bus half-duplex BUS communication mode, and the main control unit and the frequency converter can transmit data and communicate through a single bus.

[0069] The main control unit and the frequency converter can transmit communication data and time data, etc.

[0070] The main control unit is the core control unit in the storage equipment. It can be used to monitor and control various functions of the storage equipment, including temperature control and defrosting cycle.

[0071] Variable frequency drives (VFDs) can be used to control the operating status of compressors in storage equipment, etc.

[0072] The frequency converter can adjust the compressor speed according to actual needs.

[0073] The communication status between the main control device and the frequency converter can be obtained based on the communication data between them.

[0074] In some embodiments, obtaining the communication status between the main control device and the frequency converter in the storage device may include:

[0075] If a connection request is received again within four time intervals since the last connection request was received from the main control device, the communication status is determined to be normal.

[0076] If no connection request is received within four time intervals since the last connection request was received, the communication status is determined to be abnormal.

[0077] In this embodiment, the connection request information is used to enable the main control device and the frequency converter to establish a communication connection.

[0078] The main control device can send connection request information to the frequency converter through a communication interface, which may include RS-485 or RS-232, etc.

[0079] The main control device can periodically send connection request information to the frequency converter. For example, the main control device can send a connection request information to the frequency converter once every 50ms.

[0080] The fourth duration can be 3 seconds or 4 seconds, or other values, and can be user-defined; this application does not impose any restrictions.

[0081] If the frequency converter does not receive a connection request again within four time periods since the last time it received the connection request, it can be determined that the main control unit has malfunctioned and the communication connection between the main control unit and the frequency converter is abnormal.

[0082] In actual operation, during the operation of the storage equipment, the main control device can periodically send instructions to the frequency converter at certain time intervals. When the frequency converter receives the instruction, it needs to send the data related to the instruction back to the main control device, and the main control device saves the relevant data.

[0083] If, during operation, the frequency converter receives a connection request within four hours (H2s) after the last received connection request, it can be determined that the communication between the main control unit and the frequency converter is normal.

[0084] If the frequency converter does not receive a connection request from the main control unit within four hours (H2s) after the last time it received the connection request, it can be determined that the communication status is abnormal, that is, a communication failure has occurred between the main control unit and the frequency converter.

[0085] In some embodiments, when an abnormal communication status is determined, the frequency converter periodically accepts connection requests sent by the master control device.

[0086] In this embodiment, in the event of a communication failure between the main control device and the frequency converter, the frequency converter can receive a connection request from the main control device every H3s.

[0087] Within H3s, the frequency converter does not perform any testing.

[0088] Step 120: If the communication status is confirmed to be normal, control the storage device to perform a defrosting operation based on the actual temperature.

[0089] In this step, under normal communication conditions between the main control device and the frequency converter, the main control device can send instructions to the frequency converter, and the frequency converter can respond by executing the defrosting operation of the storage device.

[0090] The defrosting of storage devices can be controlled based on the actual temperature and the set temperature.

[0091] For example, when the actual temperature reaches the set temperature, the heating wire in the storage device can be controlled to work in order to perform a defrosting operation.

[0092] like Figure 2 As shown, in some embodiments, step 120 may include:

[0093] When the actual temperature of the target compartment reaches the first set temperature, the compressor in the storage device is controlled to stop rotating;

[0094] With the compressor speed set to 0, the storage device is controlled to perform a defrosting operation.

[0095] In this embodiment, the first set temperature T1 can be determined based on the set temperature range of the target room, and the value of the first set temperature can be user-defined, which is not limited in this application.

[0096] For example, if the target room's set temperature range is between -18°C and -24°C, then the first set temperature can be set to -30°C.

[0097] When the actual temperature of the target compartment reaches -30℃, a shutdown command can be sent via BUS communication to control the compressor to stop rotating.

[0098] When the compressor sends a signal indicating a true speed of 0 rpm, the main control unit can send a defrost signal, and in response to the defrost signal, the storage device will perform a defrost operation.

[0099] In some embodiments, after step 120, the method may further include:

[0100] Once it is confirmed that the communication status is normal and the actual temperature of the target room has reached the second set temperature, the storage device is controlled to exit the defrosting operation, and the compressor is controlled to start after the second time interval.

[0101] In this embodiment, the second set temperature T2 can be determined based on the first set temperature and the set temperature range of the target room, and the second set temperature is higher than the first set temperature.

[0102] For example, if the target room's set temperature range is between -18℃ and -24℃, and the first set temperature is -30℃, the second set temperature can be set to -15℃, or it can be any other value. This application does not limit the value based on user customization.

[0103] During the defrosting process of the storage equipment, the actual temperature of the target compartment will gradually rise.

[0104] If the actual temperature of the target compartment reaches the second set temperature, it can be determined that the storage equipment has completed defrosting.

[0105] The second duration (H1min) can be 1 minute or 2 minutes, or other values, and can be user-defined. This application does not impose any restrictions on it.

[0106] In actual operation, when the sensor detects that the actual temperature of the target compartment has reached T2, the storage device can be controlled to exit the defrosting operation.

[0107] After exiting the defrosting interval H1min, the compressor can be started to perform refrigeration operation.

[0108] The following is combined Figure 2 The defrosting process under normal communication conditions is explained in detail.

[0109] In actual operation, when defrosting of the freezer compartment is required, the actual temperature of the freezer compartment can be obtained.

[0110] When the actual temperature reaches -30℃, the main control unit can send a compressor stop command to the inverter via BUS communication. When the main control unit receives a message that the compressor speed is 0rpm, it can send a defrost signal and enter defrost mode.

[0111] When the temperature sensor detects that the actual temperature of the freezer compartment has reached -15℃, the storage equipment can be controlled to exit defrost mode.

[0112] Two minutes after the storage device exits defrost mode, the compressor can be started to run for cooling.

[0113] Step 130: If the communication status is determined to be abnormal, control the storage device to perform a defrosting operation based on the target runtime corresponding to the compressor in the storage device.

[0114] In this step, if the main control device malfunctions, it will be unable to send commands to the frequency converter, indicating an abnormal communication status.

[0115] The target runtime is the sum of the first continuous runtime of the compressor before the communication status abnormality and the second continuous runtime of the compressor after the communication status abnormality.

[0116] The first continuous runtime is the continuous runtime of the compressor from the moment it starts running until the moment the communication status becomes abnormal.

[0117] For example, if the compressor starts running at 10:00, and the communication status between the main control unit and the frequency converter malfunctions at 16:00 on the same day, the first continuous running time is 6 hours.

[0118] The second continuous runtime is the continuous runtime of the compressor from the moment the communication status becomes abnormal to the current data collection time.

[0119] For example, if the communication status becomes abnormal at 16:00 and the current data collection time is 20:00, the second continuous running time is 4 hours.

[0120] If an abnormal communication status is detected, it can be determined whether the storage device can be controlled to perform a defrosting operation based on the target runtime of the compressor.

[0121] In actual operation, after the communication between the main control device and the frequency converter becomes abnormal, the frequency converter can enter the fault mode. Before entering the fault mode, the compressor has been running for M1 hours. In the fault mode, the compressor runs for (M-M1) hours, that is, when the target running time of the compressor reaches M hours, the storage equipment can be controlled to perform defrosting operation.

[0122] During the research and development process, the inventors discovered that there is a method in the relevant technology that controls the storage device to perform defrosting operation based on the main control board. When the actual temperature of the target compartment reaches the set value and the defrosting conditions are met, the main control board directly controls the defrosting. However, if the main control device malfunctions, the defrosting will be abnormal or even fail to defrost. The applicable scenarios are limited, and the user experience is poor.

[0123] According to the control method for storage equipment provided in the embodiments of this application, by judging the communication status between the main control device and the frequency converter, and performing defrosting operations in different ways under different communication statuses, the applicable scenarios are broadened; when it is determined that the communication status is abnormal, the storage equipment is controlled to perform defrosting operations based on the target runtime of the compressor, which avoids the situation where the storage equipment defrosts abnormally or does not perform defrosting operations when the main control device fails, ensuring that the storage equipment can perform defrosting operations normally even when the communication status is abnormal, thus improving the user experience.

[0124] like Figure 3 As shown, in some embodiments, step 130 may further include:

[0125] When the target running duration is not greater than the first duration threshold, control the compressor to run at the first speed;

[0126] When the target running duration is greater than the first duration threshold, control the compressor to stop rotating and control the storage device to perform a defrosting operation.

[0127] In this embodiment, the first duration threshold can be 10h, or can be 96h, or can also be other values, which can be based on user definition and are not limited in this application.

[0128] The first speed is used to make the compressor perform a refrigeration operation.

[0129] When the communication state is normal, the compressor can be frequency - converted; when the communication state is abnormal, the compressor runs at the first speed.

[0130] The first speed is a fixed value. The first speed may be greater than the speed of the compressor when the communication is normal, the first speed may also be less than the speed of the compressor when the communication is normal, or the first speed may be equal to the speed of the compressor when the communication is normal. The magnitude of the first speed can be set according to actual requirements.

[0131] When the target running duration is not greater than the first duration threshold, the compressor can be controlled to continue running at the first speed until the target running duration is greater than the first duration threshold.

[0132] When the target running duration is greater than the first duration threshold, the compressor can be controlled to stop rotating and then enter the defrosting mode.

[0133] In the actual execution process, when it is determined that the communication state is abnormal, the compressor can be controlled to run at the first speed (Nrpm).

[0134] The first duration threshold can be set to Mh. When the target running duration of the compressor is M1h (M1 < M), the compressor can be controlled to run based on the first speed until the target running duration of the compressor reaches Mh.

[0135] When the target running duration is greater than Mh, the compressor can be controlled to stop rotating and the storage device can be controlled to perform a defrosting operation.

[0136] According to the control method for storage equipment provided in the embodiments of this application, the storage equipment is controlled to perform defrosting operation when the continuous running time of the compressor reaches a set threshold. This enables the system to determine whether defrosting is needed based on the continuous running time of the compressor when the communication status is abnormal and the inverter cannot receive the defrosting command sent by the main control device. This ensures the normal defrosting process of the storage equipment when the communication status is abnormal, thereby improving the user experience.

[0137] In some embodiments, after step 130, the method may further include:

[0138] If the communication status is determined to be abnormal and the continuous defrosting duration of the storage device exceeds the second duration threshold, the storage device is controlled to exit the defrosting operation, and the compressor is controlled to run at the first speed after the second duration.

[0139] In this embodiment, the continuous defrosting time corresponding to the storage device is the defrosting time from the most recent defrosting time to the current collection time.

[0140] The second duration threshold can be 0.4h or 0.5h, or other values, and can be user-defined; this application does not impose any restrictions.

[0141] It can be 1 minute or 2 minutes, or other values, which can be user-defined and are not limited in this application.

[0142] In actual implementation, such as Figure 3 As shown, after the storage device starts defrosting, the defrosting time can be timed. If the continuous defrosting time of the storage device exceeds the second time threshold (M2h), the defrosting mode will be exited.

[0143] At the second interval (H1min), the compressor can be controlled to start and run refrigeration at the first speed (Nrpm).

[0144] The following is combined Figure 3 The defrosting process under abnormal communication conditions is explained in detail.

[0145] In actual operation, if the frequency converter does not receive a connection request from the main control device within 4 seconds during operation, it can be determined that the communication status between the main control device and the frequency converter is abnormal.

[0146] In the event of an abnormal communication status, the frequency converter can accept a connection request from the main control unit every 2 seconds, and the frequency converter enters a fault mode.

[0147] If the compressor has been running for 5 hours before entering fault mode, it can be stopped and enter defrost mode after running for another 4 hours in fault mode.

[0148] If the defrosting time exceeds 30 minutes, the defrosting mode can be exited, and the compressor can be started to run at 2000 rpm for refrigeration after 2 minutes.

[0149] If a communication failure occurs between the main control unit and the frequency converter during the defrosting process, the frequency converter board can restart the timing until the defrosting time exceeds 30 minutes, at which point the defrosting process will end.

[0150] like Figure 4 As shown, in some embodiments, step 130 may further include:

[0151] During the defrosting operation of the storage equipment, once the communication status is determined to have returned to normal and a defrosting command is received from the main control device, the storage equipment is controlled to stop the defrosting operation, and the load is controlled to stop for a third duration.

[0152] Based on the actual temperature of the newly acquired target compartment, the storage equipment is controlled to perform a defrosting operation.

[0153] In this embodiment, after a communication anomaly occurs, the frequency converter can receive a connection request from the main control device every H3s.

[0154] In some embodiments, determining that the communication status has recovered from an abnormal state to a normal state may include:

[0155] When the frequency converter receives a connection request from the main control unit, it determines that the communication status has returned to normal after five hours.

[0156] In this embodiment, the fifth duration can be 2 minutes, or it can be other values, which can be user-defined and are not limited in this application.

[0157] In actual operation, if the frequency converter receives a connection request from the main control device at a certain moment during the fault operation of the storage equipment, it can maintain the current mode for five hours (H2min) before controlling the frequency converter to exit the fault mode.

[0158] Once the communication between the main control unit and the frequency converter is restored to normal, the main control unit can send commands to the frequency converter.

[0159] The defrosting command is a command sent by the main control device to the frequency converter to remove frost from the target compartment.

[0160] Load shutdown can be used to characterize the shutdown of the refrigeration system inside storage equipment.

[0161] The third duration is shorter than the fifth duration. For example, if the fifth duration is 2 minutes, the third duration can be set to 1 minute.

[0162] After the storage equipment stops defrosting, it re-acquires the actual temperature of the target compartment to resume the normal defrosting process.

[0163] In actual operation, when the storage equipment is defrosting, once the communication status is restored from abnormal to normal and the frequency converter receives the defrosting command sent by the main control device, the frequency converter can be controlled to exit the defrosting operation. The frequency converter uploads the defrosting information to the main control device, and the load stops operating for the third time (H3min).

[0164] Continue to refer to Figure 4 In some embodiments, step 130 may further include:

[0165] During the defrosting operation of the storage equipment, if the communication status is determined to have returned to normal after an abnormality and no defrosting command is received from the main control device, the storage equipment is controlled to perform the defrosting operation based on the newly acquired actual temperature of the target compartment.

[0166] In this embodiment, if the communication status returns to normal during the defrosting process and no defrosting command is received, the frequency converter can control the storage equipment to defrost according to the normal defrosting procedure.

[0167] According to the control method for storage equipment provided in the embodiments of this application, when the communication status of the storage equipment returns to normal during the defrosting process, it is determined whether the frequency converter has received the defrosting command sent by the main control device. If the defrosting command is received, the defrosting operation is exited and the normal defrosting process is entered, thus avoiding the storage equipment from defrosting twice in a short period of time, thereby reducing power consumption and avoiding resource waste.

[0168] The following is combined Figure 4 The defrosting process is explained in detail when the communication status returns to normal after an abnormal condition.

[0169] In actual operation, if the storage device recovers from a fault at a certain point during operation, it can maintain the current mode for 3 minutes before exiting the fault mode.

[0170] If the communication status of the storage equipment returns to normal during the defrosting process, and the frequency converter receives a defrosting command from the main control device, the frequency converter can exit the defrosting mode and upload the defrosting information to the main control device, controlling the load to stop operating for 2 minutes.

[0171] The control device for the storage equipment provided in this application is described below. The control device for the storage equipment described below can be referred to in correspondence with the control method for the storage equipment described above.

[0172] The control method for storage devices provided in this application can be executed by a control device for the storage device. This application uses the example of a control device executing the control method for the storage device to illustrate the control device for the storage device provided in this application.

[0173] This application also provides a control device for a storage device.

[0174] like Figure 5 As shown, the control device for the storage equipment includes: a first processing module 510, a second processing module 520, and a third processing module 530.

[0175] The first processing module 510 is used to obtain the actual temperature of the target compartment in the storage equipment and the communication status between the main control device and the frequency converter in the storage equipment.

[0176] The second processing module 520 is used to control the storage device to perform a defrosting operation based on the actual temperature when the communication status is determined to be normal.

[0177] The third processing module 530 is used to control the storage device to perform a defrosting operation based on the target runtime corresponding to the compressor in the storage device when it is determined that the communication status is abnormal; the target runtime is the sum of the first continuous runtime of the compressor before the communication status is abnormal and the second continuous runtime of the compressor after the communication status is abnormal.

[0178] The control device for storage equipment provided in the embodiments of this application expands the applicable scenarios by judging the communication status between the main control device and the frequency converter and performing defrosting operations in different ways under different communication statuses. When it is determined that the communication status is abnormal, the storage equipment is controlled to perform defrosting operations based on the target runtime of the compressor. This avoids the situation where the storage equipment defrosts abnormally or does not perform defrosting operations when the main control device fails, ensuring that the storage equipment can perform defrosting operations normally even when the communication status is abnormal, thus improving the user experience.

[0179] In some embodiments, the third processing module 530 can also be used for:

[0180] If the target runtime is not greater than the first runtime threshold, control the compressor to run at the first speed;

[0181] If the target runtime exceeds the first duration threshold, control the compressor to stop rotating and control the storage device to perform a defrosting operation.

[0182] In some embodiments, the control device of the storage device may further include a fourth processing module for:

[0183] After controlling the storage device to perform defrosting operation based on the target runtime corresponding to the compressor in the storage device, if it is determined that the communication status is abnormal and the continuous defrosting duration corresponding to the storage device is greater than the second duration threshold, the storage device is controlled to exit the defrosting operation, and the compressor is controlled to run at the first speed after the second duration.

[0184] In some embodiments, the third processing module 530 can also be used for:

[0185] During the defrosting operation of the storage equipment, once the communication status is determined to have returned to normal and a defrosting command is received from the main control device, the storage equipment is controlled to stop the defrosting operation, and the load is controlled to stop for a third duration.

[0186] Based on the actual temperature of the newly acquired target compartment, the storage equipment is controlled to perform a defrosting operation.

[0187] In some embodiments, the third processing module 530 can also be used for:

[0188] During the defrosting operation of the storage equipment, if the communication status is determined to have returned to normal after an abnormality and no defrosting command is received from the main control device, the storage equipment is controlled to perform the defrosting operation based on the newly acquired actual temperature of the target compartment.

[0189] In some embodiments, the first processing module 510 may also be used for:

[0190] If a connection request is received again within four time intervals since the last connection request was received from the main control device, the communication status is determined to be normal.

[0191] If no connection request is received within four time intervals since the last connection request was received, the communication status is determined to be abnormal.

[0192] The control device for the storage device in this application embodiment can be a device with an operating system. This operating system can be Android, iOS, or other possible operating systems; this application embodiment does not specifically limit the specific operating system used.
