[0067] Embodiments of the present disclosure are described below in detail with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present disclosure, and are not to be understood as limiting the present disclosure.

[0068] A compressor restart control method, device, electronic equipment and storage medium of embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0069] Figure 1 A flowchart of a compressor restart control method provided by an embodiment of the present disclosure is shown in FIG. 1. As shown in FIG. 1, the compressor restart control method includes but is not limited to the following steps: Figure 1

[0070] S101, obtaining a current external environment temperature of the compressor.

[0071] In an embodiment of the present disclosure, a temperature sensor can be deployed on the outdoor unit to detect the external environment temperature. The compressor and the temperature sensor on the outdoor unit can be connected by wireless or wired means, and the temperature sensor can report the detected external environment temperature to the compressor at regular intervals or periodically. Alternatively, the compressor can read the external environment temperature detected by the temperature sensor at regular intervals or periodically.

[0072] Optionally, the temperature sensor can be one or more, and in the case of multiple, the average value can be determined as the external environment temperature by averaging the temperatures collected by the temperature sensors.

[0073] It can be understood that the sampling signal of the temperature sensor is obtained, and the sampling signal is filtered, and further, the filtered sampling signal is converted into an analog-to-digital (AD) signal to obtain the external environment temperature.

[0074] S102, obtaining a current cumulative restart failure number of the compressor.

[0075] During operation of the air conditioner, compressor failure can occur. In order to ensure that the air conditioner can continue to operate after the failure occurs, the compressor can be restarted to remove or recover the failure. For example, the compressor can have overheat or overpressure failure, and the overheat protection or overpressure protection can be performed by restarting

[0076] In an embodiment of the present disclosure, the compressor restart failure number can be counted during the restart phase of the compressor to obtain the current cumulative restart failure number of the compressor. It can be understood that the cumulative restart failure number is a cumulative value of a restart phase.

[0077] ​Optionally, a counter can be arranged in the compressor, and the counter is started synchronously after the compressor receives the restart instruction, and the count value of the counter is zero at this time. The count value of the counter is incremented by one each time the compressor fails to restart, and thus the cumulative number of restart failures can be obtained.

[0078] S103, determining whether the compressor enters a fault locking state according to the cumulative number of restart failures.

[0079] S104, determining a target restart control parameter for the next restart of the compressor according to the external environment temperature when the compressor does not enter the fault locking state.

[0080] In the embodiment of the application, when the number of restart failures of the compressor is large, it can be determined that the compressor enters the fault locking state. When the compressor enters the fault locking state, if the compressor is restarted continuously according to the default restart control parameter, the compressor can not be restarted successfully, and frequent restarts can cause damage to the compressor. In the embodiment of the application, in order to avoid frequent restarts, the fault locking state is set, and if the compressor enters the fault locking state, the compressor does not restart.

[0081] It should be noted that the restart control parameter in the embodiment of the application can be a proportion adjustment coefficient Kp parameter in a proportion-integral-differential (PID) regulator. The Kp parameter can accelerate the response speed of the system, improve the adjustment accuracy of the system, and quickly adjust errors in the PID regulator.

[0082] In the implementation, the external environment temperature is an important factor affecting the successful restart of the compressor. In order to successfully restart the compressor, in the embodiment of the application, when the compressor does not enter the fault locking state, the target restart control parameter for the next restart of the compressor can be determined according to the external environment temperature, so that the target restart control parameter of the compressor can be related to the external environment temperature, and thus the next restart of the compressor can be performed by considering the external environment temperature, thereby improving the possibility of successful restart of the compressor.

[0083] Optionally, a mapping relationship between the external environment temperature and the restart control parameter can be established in advance. Further, after the external environment temperature is obtained, the mapping relationship is queried, and the restart control parameter that is mapped with the external environment temperature can be obtained. In the embodiment of the application, the restart control parameter that is mapped with the external environment temperature can be determined as the target restart control parameter for the next restart of the compressor.

[0084] S105, controlling the compressor to restart next time according to the target restart control parameter.

[0085] In order to enable the compressor to restart successfully as much as possible next time, the compressor needs to be controlled to restart next time according to the target restart control parameter, that is, the compressor needs to take the target restart control parameter as an input parameter of the PID regulator during the next restart.

[0086] In the embodiment of the application, during the compressor restart process, the current cumulative restart failure number of the compressor and the current external environment temperature of the compressor are obtained, further, whether the compressor enters a fault locking state is judged according to the cumulative restart failure number, when the compressor is not in the fault locking state, the target restart control parameter of the compressor during the next restart is determined according to the external environment temperature, and the compressor is controlled to restart next time according to the target restart control parameter. In the embodiment of the application, not only the restart failure number of the compressor can be recorded, but also when the restart failure number indicates that the compressor enters the fault locking state, the target restart control parameter of the compressor during the next restart can be determined by considering the influence of the external environment temperature, so that the target restart control parameter of the compressor can be related to the external environment temperature, and the restart control parameter, that is, the Kp parameter, can be adaptively adjusted following the external environment temperature, thereby the possibility of successful restart of the compressor can be improved.

[0087] Figure 2 Another flowchart of a compressor restart control method provided by the embodiment of the application is shown in FIG. 6. As shown in FIG. 6, the compressor restart control method includes but is not limited to the following steps: Figure 2

[0088] S201, obtaining the current external environment temperature of the compressor.

[0089] For specific introduction of step S201, reference can be made to the related content in the above embodiment, such as the description of step S101, which will not be repeated here.

[0090] S202, obtaining the current cumulative restart failure number of the compressor.

[0091] Optionally, a restart failure determination condition is set in advance, when the current restart of the compressor meets the restart failure determination condition, it is determined that the current restart of the compressor fails, and the cumulative restart failure number is updated. For example, the counter can be operated by 1.

[0092] In some implementations, the restart running duration of the current restart of the compressor is obtained, when the restart running duration is greater than the set start failure determination duration and the compressor appears out of step, it is determined that the current restart of the compressor fails, and the cumulative restart failure number is updated. That is, the preset restart failure determination condition can be that the restart running duration is greater than the set start failure determination duration and the compressor appears out of step,

[0093] ​In the embodiments of the present application, the running parameters of the compressor can be monitored, for example, including the compressor start-up gain, the current loop bandwidth parameter, the switching frequency, etc., and when the above running parameters are abnormal, it can be determined that the compressor is out of step. For example, when the switching frequency exceeds the set frequency limit, it can be determined that the compressor is out of step.

[0094] In S203, the accumulated restart failure number is compared with the set start-up locking number, and when the accumulated restart failure number does not reach the start-up locking number, it is determined that the compressor does not enter the fault locking state.

[0095] In the embodiments of the present application, a start-up locking number is set in advance, and after the accumulated restart failure number is obtained, whether the compressor enters the fault locking state can be determined based on the accumulated restart failure number and the start-up locking number. Alternatively, the accumulated restart failure number is compared with the set start-up locking number, and when the accumulated restart failure number does not reach the start-up locking number, it is determined that the compressor does not enter the fault locking state, and then step S204 is continued.

[0096] Alternatively, when the accumulated restart failure number reaches the start-up locking number, it is determined that the compressor enters the fault locking state, and step S206 is executed.

[0097] In S204, the size relationship between the external environment temperature and the set temperature threshold value is determined, and the target parameter correction threshold value of the next restart of the compressor is determined according to the size relationship.

[0098] In the embodiments of the present application, a temperature threshold value is set in advance, and after the external environment temperature is obtained, the external environment temperature and the set temperature threshold value can be compared to determine the size relationship between the external environment temperature and the temperature threshold value. Further, the target parameter correction threshold value of the next restart of the compressor can be determined according to the size relationship.

[0099] Through the set temperature threshold value, the temperature interval in which the external environment temperature is located can be determined, and different temperature intervals can correspond to different parameter correction threshold values, so that the adjustment of the restart control parameter is more accurate.

[0100] Alternatively, the temperature threshold value can be one or more, and in the case of multiple, a temperature interval can be determined based on the size of adjacent temperature threshold values, and the target parameter correction threshold value corresponding to the external environment temperature can be determined according to the temperature interval of the external environment temperature.

[0101] In S205, the target restart control parameter is determined according to the target parameter correction threshold value and the current restart control parameter at this time, and the compressor is controlled to restart next time according to the target restart control parameter.

[0102] In some implementations, a parameter increment can be obtained according to the accumulated restart failure number and the target parameter correction threshold. Further, the target restart control parameter can be determined according to the parameter increment and the current restart control parameter.

[0103] For example, a product of the accumulated restart failure number and the target parameter correction threshold is obtained, and the product is taken as the parameter increment. Further, a sum of the parameter increment and the current restart control parameter is obtained, and the sum is determined as the target restart control parameter.

[0104] Taking the target restart control parameter as the Kp parameter as an example, the target restart control parameter can be determined by using the following formula:

[0105] Target restart Kp parameter = current restart Kp parameter + target parameter correction threshold * accumulated restart failure number.

[0106] S206, when the compressor enters the fault locking state, stop continuing to perform the restart process on the compressor, and / or, an alarm information of restart protection failure is generated.

[0107] In a case where it is determined that the compressor enters the fault locking state, i.e., the accumulated restart failure number reaches the start locking number, it indicates that the Kp parameter is still unable to successfully restart the compressor after multiple adjustments. In order to avoid the harm caused by frequent restarts to the compressor, the restart process on the compressor can be stopped.

[0108] Optionally, the compressor is controlled to generate an alarm information of restart failure. In some implementations, the alarm information can be displayed on a display panel of the air conditioner, or the alarm information can be displayed on a remote controller of the air conditioner, or the alarm information can be generated through a buzzer of the air conditioner, or the alarm information can be sent to a terminal device associated with the air conditioner.

[0109] In the embodiments of the present application, not only the restart failure number of the compressor can be recorded, but also in a case where the restart failure number indicates that the compressor enters the fault locking state, the influence of the external environment temperature can be considered when determining the target restart control parameter of the compressor next time, so that the target restart control parameter of the compressor can be related to the external environment temperature, and the restart control parameter, i.e., the Kp parameter, can be adaptively adjusted following the external environment temperature, thereby improving the possibility of successful restart of the compressor.

[0110] Figure 3 Another flowchart of a compressor restart control method provided by the embodiments of the present application is shown in FIG. 6. As shown in FIG. 6, the compressor restart control method includes but is not limited to the following steps: Figure 3

[0111] S301, an external environment temperature of the compressor is obtained.

[0112] ​For a detailed description of step S301, please refer to the relevant content in the above embodiment, such as the detailed description of 102, which will not be repeated here.

[0113] S302, obtain the restart runtime of the compressor during the current restart.

[0114] S303: If the restart runtime exceeds the set start failure determination time and the compressor loses synchronization, the compressor is determined to have failed to restart and the cumulative number of restart failures is updated.

[0115] S304 determines whether the external ambient temperature is greater than the set temperature threshold.

[0116] It is understandable that ambient temperature can reflect load conditions; higher ambient temperatures generally indicate a larger load, and lower ambient temperatures generally indicate a smaller load. If the ambient temperature is higher than a set temperature threshold, it indicates a higher load; if the ambient temperature is lower than or equal to the set temperature threshold, it indicates a lower load. In this embodiment, a low-load parameter correction threshold can be applied when the ambient temperature is low, and a high-load parameter correction threshold can be applied when the ambient temperature is high.

[0117] S305 determines whether the cumulative number of failed restarts exceeds the set number of startup lockouts.

[0118] If the cumulative number of failed restarts is less than or equal to the set number of startup lockouts, and the external ambient temperature is less than or equal to the temperature threshold, proceed to step S306.

[0119] If the cumulative number of failed restarts is less than or equal to the set number of startup lockouts, and the external ambient temperature is greater than or equal to the temperature threshold, proceed to step S307.

[0120] If the cumulative number of failed restarts exceeds the set number of startup lockouts, proceed to step S308.

[0121] It is understandable that S305 will continue to be executed when the external ambient temperature is higher than the set temperature threshold, and S305 will still be executed when the external ambient temperature is lower than or equal to the set temperature threshold. Figure 3 Although two S305s are shown, they are actually one step.

[0122] S306, determine the low-load parameter correction threshold of the compressor as the target parameter correction threshold, and determine the target restart control parameter based on the target parameter correction threshold and the current restart control parameter at the time of restart.

[0123] The product of the accumulated restart failure number and the low-load parameter correction threshold is obtained, and the product is taken as a parameter increment. Further, the sum of the parameter increment and the current restart control parameter is obtained, and the sum is determined as the target restart control parameter.

[0124] Taking the target restart control parameter as a Kp parameter, the target restart control parameter can be determined by the following formula:

[0125] The target restart Kp parameter = the current restart Kp parameter + the high-load parameter correction threshold * the accumulated restart failure number.

[0126] S307, determining that the high-load parameter correction threshold of the compressor is the target parameter correction threshold, and determining the target restart control parameter according to the target parameter correction threshold and the current restart control parameter at the time of the restart.

[0127] The product of the accumulated restart failure number and the high-load parameter correction threshold is obtained, and the product is taken as a parameter increment. Further, the sum of the parameter increment and the current restart control parameter is obtained, and the sum is determined as the target restart control parameter.

[0128] Taking the target restart control parameter as a Kp parameter, the target restart control parameter can be determined by the following formula:

[0129] The target restart Kp parameter = the current restart Kp parameter + the high-load parameter correction threshold * the accumulated restart failure number.

[0130] S308, stopping the restart process of the compressor, and / or issuing a restart failure reminder.

[0131] For specific introduction of step S308, refer to the specific introduction of the related content in the above embodiments, such as 102, which will not be repeated here.

[0132] S309, controlling the compressor to restart next time according to the target restart control parameter.

[0133] For example, the judgment time of the compressor start failure is set to 2 minutes (min), and the temperature threshold of the compressor can be 43 degrees (℃). The temperature threshold is used to partition the external environment temperature, so as to obtain different parameter correction thresholds. The start failure locking number of the compressor can be set to 6 times, the high-load correction threshold of the Kp parameter can be 20, and the low-load correction threshold of the Kp parameter can be 10.

[0134] When the duration of the current restart of the compressor exceeds 2 min and the compressor is out of step, it can be determined that the current restart of the compressor fails, and the cumulative restart failure number can be increased by 1. If the collected external environment temperature is 45℃ and the cumulative restart failure number is 5 times. At this time, the external environment temperature is greater than 43℃, and the cumulative restart failure number is less than 6 times, so the correction parameter threshold can be determined as the high load correction threshold 20.

[0135] If the collected external environment temperature is 40℃ and the cumulative restart failure number is 5 times. At this time, the external environment temperature is less than 43℃, and the cumulative restart failure number is less than 6 times, so the correction parameter threshold can be determined as the low load correction threshold 20.

[0136] If the collected external environment temperature is 42℃ and the cumulative restart failure number is 6 times. In the embodiment of the application, at this time, the external environment temperature is less than 43℃, but the cumulative restart failure number reaches 6 times, so it can be determined that the compressor enters a fault locking state, stops the next restart of the compressor, and / or sends a restart failure reminder.

[0137] In the embodiment of the application, not only the restart failure number of the compressor can be recorded, but also in the case where the restart failure number indicates that the compressor enters a fault locking state, the influence of the external environment temperature can be considered when determining the target restart control parameter of the next restart of the compressor, so that the target restart control parameter of the compressor can be related to the external environment temperature, and the restart control parameter Kp can be adaptively adjusted according to the external environment temperature, thereby improving the possibility of successful restart of the compressor. Moreover, since the external environment temperature can reflect the load condition, referring to the influence of the external environment temperature can reduce the probability of restart failure under different loads.

[0138] To realize the above-mentioned embodiments, the disclosure further provides a compressor restart control device.

[0157] determine the target restart control parameter according to the parameter increment and the current restart control parameter.

[0158] In an embodiment of the present disclosure, the control module 450 is further configured to:

[0159] When the compressor enters the fault locking state, stopping the restart procedure of the compressor; and / or, sending a restart failure prompt.

[0160] In an embodiment of the present disclosure, the first obtaining module is further configured to:

[0161] obtaining the restart running duration of the compressor in the current restart;

[0162] When the restart running duration is greater than the set start failure determination duration and the compressor is out of step, determining that the current restart of the compressor fails, and updating the accumulated restart failure number.

[0163] It should be noted that the foregoing description of the embodiment of the compressor restart control method is also applicable to the compressor restart control device of the embodiment, which will not be described here.

[0164] In the embodiment of the present application, during the restart of the compressor, the current accumulated restart failure number of the compressor and the current external environment temperature of the compressor are obtained, and further, whether the compressor enters the fault locking state is determined according to the accumulated restart failure number. When the compressor is not in the fault locking state, the target restart control parameter of the next restart of the compressor is determined according to the external environment temperature, and the compressor is controlled to restart according to the target restart control parameter. In the present application, not only the restart failure number of the compressor can be recorded, but also when the restart failure number indicates that the compressor enters the fault locking state, the target restart control parameter of the next restart of the compressor can be determined considering the influence of the external environment temperature, so that the target restart control parameter of the compressor can be related to the external environment temperature, and the restart control parameter, i.e., the Kp parameter, can be adaptively adjusted according to the external environment temperature, thereby improving the possibility of successful restart of the compressor. Moreover, since the external environment temperature can reflect the load condition, referring to the influence of the external environment temperature can reduce the probability of restart failure under different loads.
