It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without the use of these specific details.

Therefore, the present application is not intended to be limited to the embodiments shown, but rather to be in line with the broadest scope consistent with the principles and features disclosed in the present application.
[0054] The present application provides a refrigeration equipment control method, device, equipment, and storage medium, which will be described in detail below.
[0055] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the scenario of the refrigeration equipment control system provided by the embodiments of the present application. The refrigeration equipment control system may include a refrigeration equipment 100. As Figure 1 in the refrigeration equipment 100, the relevant control logic stored in the refrigeration equipment 100 can be obtained to execute the refrigeration equipment control method in the present application.
[0056] In the embodiments of the present application, the refrigeration equipment 100 may include, but is not limited to, a double-door refrigerator, a single-door refrigerator, a freezer, etc.
[0057] It should be noted that Figure 1 the schematic diagram of the scenario of the refrigeration equipment control system shown is only an example. The refrigeration equipment control system and scenario described in the embodiments of the present application are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art can know that with the evolution of the refrigeration equipment control system and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.
[0058] As Figure 2 shown, Figure 2 which is a schematic flowchart of an embodiment of the refrigeration equipment control method in the embodiments of the present application. The method specifically includes the following steps 201 to 203:
[0059] 201. Determine whether the target refrigeration equipment is in a networked state.
[0060] In the embodiments of the present application, determining whether the target refrigeration equipment is in a networked state can be achieved by determining whether the current target refrigeration equipment is in a networked mode, or whether it is connected to a wifi network, or whether it can perform network data communication after connecting to the wifi network. Specifically, the embodiments of the present application do not make limitations.
[0061] 202. If the target refrigeration device is not in a networked state, determine the current time information according to the offline timing time of the target refrigeration device.
[0062] According to the above steps, if the target refrigeration device is not in a networked state, the target refrigeration device cannot synchronize time information through the network. Therefore, if it reaches night or the noise reduction time specified by the user, it may cause the noise reduction to not proceed smoothly, or the time information of the target refrigeration device to be disordered, resulting in noise reduction at the wrong time.
[0063] Based on this, in the embodiment of the present application, a timer that does not rely on the network can be set in advance in the target refrigeration device and used for offline timing to obtain the offline timing time. Among them, the offline timing time can include days timing, hours timing, minutes timing, etc. Specifically, every 60 minutes of minutes timing, the hours timing is incremented by 1; every 24 hours of hours timing, the days timing is incremented by 1. At the same time, the minutes timing is cleared every 60 minutes and starts from 0 again for minutes timing; the hours timing is cleared every 24 hours and starts from 0 again for hours timing. The days timing can be cleared regularly or manually, and the embodiment of the present application does not limit it. In addition, the timer in the present application can adopt any solution with a timing function, such as program timing, etc., and the embodiment of the present application also does not limit it. At the same time, as long as the moment when the offline timing starts coincides with zero o'clock, the offline timing time is the current time information.
[0064] 203. Control whether the target refrigeration device enters the target noise reduction mode according to the current time information.
[0065] According to the above steps, the target refrigeration device can perform offline timing, so as to obtain the current time information. Therefore, after obtaining the current time information, noise reduction can be performed according to the specific noise reduction settings. For example: the target refrigeration device can include an initial noise reduction time, such as from 0:00 am to 6:00 am. When the current time information is within this time interval, the processor of the target refrigeration device can control the target refrigeration device to enter the target noise reduction mode for noise reduction.
[0066] Alternatively, the user can also set the specific time for the target refrigeration device to enter the target noise reduction mode to meet personalized noise reduction needs. For example: if the user has the habit of taking a nap, a nap time interval can be set, such as from 12:30 to 2:00, etc. When the current time information is within this time interval, the processor controls the target refrigeration device to enter the target noise reduction mode for noise reduction, etc.
[0067] Among them, the target noise reduction mode can include any noise reduction parameters, such as initial noise reduction parameters, or user-set noise reduction parameters, such as controlling the overall working power of the target refrigeration device, controlling the specific refrigeration temperature of the target refrigeration device, etc. Specifically, the embodiments of the present application do not limit it.
[0068] For the refrigeration device control method provided by the present application, it can first be determined whether the target refrigeration device is in a networked state. If the target refrigeration device is not in a networked state, the current time information can be determined according to the offline timing time of the target refrigeration device. If it is determined that the current time information is in a time period that requires noise reduction, then enter the target noise reduction mode for noise reduction, which can prevent the refrigeration device from being unable to determine the current time when there is no network, thereby avoiding the problems of noise reduction failure or incorrect noise reduction time.
[0069] In order to better implement the embodiments of the present application, in one embodiment of the present application, the offline timing time is obtained by timing through the target crystal oscillator model; the method further includes:
[0070] Determine whether the offline timing time exceeds the target time threshold; if the offline timing time exceeds the target time threshold, determine the current crystal oscillator accuracy of the target crystal oscillator model; according to the current crystal oscillator accuracy and the offline timing time, determine the current error duration; according to the current error duration, adjust the current crystal oscillator accuracy to calibrate the offline timing, and then obtain the offline timing time.
[0071] The above embodiments provide a solution that enables the target refrigeration device to determine the current time information in the case of no network by means of offline timing.
[0072] Among them, the above embodiments provide a solution for timing through a timing program. However, a refrigeration device is an electrical device that requires electricity as an energy source. Therefore, if a power outage occurs, the refrigeration device will stop operating, resulting in the failure of the timing program. Therefore, only a backup power supply can be added to the refrigeration device, but it is very difficult to implement this method in ordinary application scenarios. For example, when using a refrigerator at home, it is impossible to ensure that a backup generator is set up for the refrigerator.
[0073] Based on this, the present application also provides a solution for off-line timing using a crystal oscillator. Specifically, the chip crystal oscillator can be used for timing. For example, the chip can generate a stable and accurate clock signal through a high-precision crystal oscillator. At the same time, a button battery can be set, such as CR2477 (1000 mah, 3V), etc., to supply power to the crystal oscillator chip during power-off. For example, when the refrigeration equipment enters the power-off scenario, the chip is in the low-power mode, and the required current is approximately 25 uA, and the power supply time is up to 1000 / 25 * 1000 h ≈ 4.56 years. Thus, it can be seen that in the case of power-off, off-line timing can be achieved without a backup power supply. In addition, the battery capacity can be appropriately increased or decreased according to actual needs, and it can be removed and replaced after running out of power.
[0074] It should be noted that the chip crystal oscillator belongs to off-line timing. If there is a network, the time can be calibrated through the network. However, without a network, the off-line timing time cannot be calibrated through the network. Therefore, in order to improve the accuracy of off-line timing, off-line calibration for the off-line timing time is also required.
[0075] When using a crystal oscillator for off-line timing, there may be a certain error offset in the frequency of the generated clock signal. For example, from a few ppm to dozens of ppm. When adjusting the error frequency of the crystal oscillator, the offset cannot be completely eliminated, that is, there must be an error in the crystal oscillator accuracy. Therefore, after manually adjusting the crystal oscillator accuracy to the current crystal oscillator accuracy, off-line timing can start. From this, it can be deduced that when off-line timing is performed according to a certain error, after a long time, there will be a deviation in the off-line timing time. This is also the reason why off-line calibration is required. If the off-line timing time exceeds the target time threshold, it can be determined that the off-line timing time exceeds a certain deviation, and at this time, time calibration is required. For example, when the current crystal oscillator accuracy adjusted manually is +5 ppm, subsequently, the target crystal oscillator model can be used for adjustment, such as adjusting to -5 ppm. In this way, assuming that the previous time was delayed, by adjusting the crystal oscillator accuracy, the timing can be accelerated, thereby offsetting the problem of the delayed timing time.
[0076] Among them, the adjustment logic of the target crystal oscillator model can be understood as taking the determined current crystal oscillator accuracy and the specific timing duration as model inputs. Then, the crystal oscillator accuracy opposite to the current crystal oscillator accuracy and the specific execution duration are output. The execution duration can be equal to the timing duration, thus completing the time offset. For example, if the time is delayed, the timing can be accelerated; or, if the timing time is slightly fast, the effect of delayed timing can be achieved.
[0077] However, it should be noted that 5 ppm is equal to 5 / 1000000 = 0.000005; taking an 8M crystal oscillator as an example, the error time for timing ten years (3650 days) is 315360000 seconds * 5 / 1000000 = 1576.8 seconds ≈ 26 minutes. Without considering the aging rate, for timing 10 years, there is only a timing error of 26 minutes, and this error is completely acceptable. However, the larger the ppm value, that is, the lower the precision of the crystal oscillator, the greater the time deviation. Therefore, the target time threshold can be set according to the actual situation, and the embodiments of the present application do not limit it.
[0078] In order to better implement the embodiments of the present application, in one embodiment of the present application, controlling whether the target refrigeration device enters the target noise reduction mode according to the current time information includes:
[0079] If the current time information belongs to the target time interval, control the target refrigeration device to enter the target noise reduction mode; if entering the target noise reduction mode, control the target refrigeration device to operate according to the target noise reduction setting.
[0080] The above embodiments provide a solution for entering the target noise reduction mode for noise reduction. However, conventional noise reduction methods may not be able to meet the user's noise reduction requirements. In addition to the user being able to customize the specific noise reduction time, for example: setting the time to start the target noise reduction mode, including: start time intervals such as 22:00 - 6:00, 9:00 - 12:00, 14:00 - 6:00, etc. At this time, if the current time information belongs to these time intervals, the target noise reduction mode is started.
[0081] In addition, the target noise reduction mode can be different from the traditional noise reduction function. For example, when the refrigeration device reaches the refrigeration temperature, it will actively reduce the frequency of the compressor, and this situation belongs to conventional noise reduction. The target noise reduction mode of the present application can be different from the traditional noise reduction. For example: the current ambient temperature can be obtained to determine specific noise reduction parameters. Among them, determining specific noise reduction parameters according to the current ambient temperature can be understood as that the target noise reduction setting needs to refer to the current ambient temperature; for example: the lower the temperature, the lower the possibility of food spoilage, and the operating temperature of the refrigeration device can be appropriately increased, which can effectively reduce the operating power of the refrigeration device, thereby reducing noise. Or the current ambient humidity can be combined to determine specific noise reduction parameters. For example, the lower the humidity, the condensation work can be appropriately reduced. At this time, a certain amount of refrigeration device power can also be saved, thereby achieving noise reduction, etc.
[0082] In addition, the user can also manually enter the target noise reduction mode or manually turn off the target noise reduction mode by controlling the mobile phone app or the control panel of the refrigeration device. For example: if the user issues an instruction to enter the target noise reduction mode through the mobile phone app or the control panel of the refrigeration device, it is determined to enter the target noise reduction mode, or the user can control to turn off the target noise reduction mode.
[0083] In order to better implement the embodiments of the present application, in one embodiment of the present application, the target noise reduction setting includes adjusting the refrigeration start-stop temperature and adjusting the freezing start-stop temperature; controlling the target refrigeration device to operate according to the target noise reduction setting includes:
[0084] If the current refrigeration start-stop temperature is lower than the target refrigeration start-stop temperature, adjust the current refrigeration start-stop temperature to the target refrigeration start-stop temperature; if the current freezing start-stop temperature is lower than the target freezing start-stop temperature, adjust the current freezing start-stop temperature to the target freezing start-stop temperature.
[0085] The above embodiments provide a control according to the set target noise reduction setting. The embodiments of the present application also provide a more detailed control scheme. Specifically, the refrigeration start-stop temperature and the freezing start-stop temperature of the user can be detected first. If the refrigeration start-stop temperature or the freezing start-stop temperature is too low, the refrigeration start-stop temperature and the freezing start-stop temperature can be appropriately increased. For example: if the current refrigeration start-stop temperature is less than 5 degrees, adjust the current refrigeration start-stop temperature to the target refrigeration start-stop temperature, 5 degrees; or, if the current freezing start-stop temperature is less than -18, adjust the current freezing start-stop temperature up to the target freezing start-stop temperature, -18. Of course, the specific adjustment range can be set according to the actual situation, and the embodiments of the present application do not limit it.
[0086] In order to better implement the embodiments of the present application, in one embodiment of the present application, the target noise reduction setting includes adjusting the compressor speed; controlling the target refrigeration device to operate according to the target noise reduction setting includes:
[0087] If the current compressor speed gear is the minimum gear, the speed of the compressor is not adjusted; if the current compressor speed gear is not the minimum gear, determine the target compressor speed gear that is less than the current compressor speed gear and adjacent; reduce the current compressor speed gear to the target compressor speed gear.
[0088] In the embodiments of the present application, the compressor speed gear can be set according to different situations, and at the same time, different models of refrigerators have different numbers of set gears, so the present application does not limit it. In addition, reducing the current compressor speed gear to the target compressor speed gear can be understood as lowering the compressor speed gear by one gear.
[0089] Specifically, the starting current of the compressor is large, and the electromagnetic noise generated is relatively large instantaneously. After the noise reduction function is turned on, the compressor steps from a low speed to a specified speed, and comprehensively judges the working time and speed of the compressor according to the ambient temperature, freezer temperature, refrigerator temperature and compressor startup time. The speed is reduced by 30 - 900 r / min compared to the original speed, roughly reducing one gear for all speeds of the compressor. If the current is the lowest speed gear, the gear will not be reduced.
[0090] In order to better implement the embodiments of the present application, in one embodiment of the present application, the target noise reduction setting includes adjusting the speed of the refrigeration fan; controlling the target refrigeration device to operate according to the target noise reduction setting, including:
[0091] Lower the current refrigeration speed of the refrigeration fan to the target refrigeration speed; obtain the current ambient temperature; according to the current ambient temperature, determine the corresponding target ambient temperature range, and the target ambient temperature range corresponds to the target refrigeration fan speed gear; adjust the target refrigeration speed to the target refrigeration fan speed gear.
[0092] In the embodiments of the present application, a solution for specifically adjusting the speed of the refrigeration fan is provided. Specifically, when the speed of the fan reaches a certain range, the noise increases significantly and shows a positive correlation. After the noise reduction function is turned on, the fan steps from a low speed to a specified speed, and comprehensively judges the fan speed according to the ambient temperature, freezer temperature, refrigerator temperature and compressor speed. The voltage measured by the sampling circuit is reduced by 0.5 - 3V compared to the original voltage. Some rules are as follows:
[0093]
[0094] Among them, each temperature range is the target ambient temperature range in the embodiments of the present application. At the same time, the actual speed of each gear of the fan speed can be set according to specific circumstances, and the embodiments of the present application do not limit it.
[0095] In order to better implement the embodiments of the present application, in one embodiment of the present application, the target noise reduction setting includes adjusting the speed of the condenser fan; controlling the target refrigeration device to operate according to the target noise reduction setting, including:
[0096] Lower the current condenser speed of the condenser fan to the target condenser speed; obtain the current ambient temperature; according to the current ambient temperature, determine the corresponding target ambient temperature range, and the target ambient temperature range corresponds to the target condenser fan speed gear; adjust the target condenser speed to the target condenser fan speed gear.
[0097] Similar to the above embodiments, the control of the condenser fan can be as follows:
[0098]
[0099] In addition, in the embodiments of the present application, the ambient temperature and humidity can be obtained by installing corresponding temperature sensors and humidity sensors. Meanwhile, the installation positions of the temperature sensors and humidity sensors can be set according to the actual situation, and the embodiments of the present application do not limit them.
[0100] Under normal operating conditions, the operating modes of the refrigeration equipment can include: 1) Calculating the normal on-off points based on the set temperature of the refrigerating chamber. 2) Calculating the normal on-off points based on the set temperature of the freezing chamber. 3) The compressor gear can directly jump. 4) The gears of the freezing fan and the condensing fan are normally turned on according to the ambient temperature and humidity.
[0101] It should also be noted that in the embodiments of the present application, when the target refrigeration equipment is in the networked state, the offline timing time can be calibrated through the network. Meanwhile, the current time can be directly obtained through the network, so as to control the corresponding noise reduction logic.
[0102] In addition, according to the above description, the user can manually set the time interval. Based on this, the embodiments of the present application also provide a manual setting method for the user. For example: The user can use the combination keys to enter the set time mode. For example, long press the temperature zone for 5s to enter the set time mode. The indicator light of the refrigerating chamber represents hours, the indicator light of the variable temperature chamber represents minutes, and the indicator light of the freezing chamber represents seconds. The plus and minus keys can set the time, the display panel displays the corresponding time, and the time zone switches for the setting of hours, minutes, and seconds. After completion, long press the temperature zone for 5s to exit the set time mode, and record the time converted in the 24-hour system for hours, minutes, and seconds, etc.
[0103] To better implement the refrigeration equipment control method in the embodiments of the present application, on the basis of the refrigeration equipment control method, the embodiments of the present application also provide a refrigeration equipment control device, as Figure 3 shown. The device 300 includes:

If it is determined that the current time information is in a time period that requires noise reduction, the control module 302 can enter the target noise reduction mode for noise reduction, preventing the refrigeration equipment from being unable to determine the current time when there is no network, thereby avoiding the problems of noise reduction failure or incorrect noise reduction time.
