[0037] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0039] A control method, device, clothing processing device and medium for clothing processing equipment provided by an embodiment of the present disclosure will be exemplarily described below in conjunction with the accompanying drawings.

[0040] Figure 1 A schematic flow chart of a control method for a clothes processing device provided in an embodiment of the present disclosure includes:

[0041] S101, determining that a clock source of a controller of a laundry processing device is an external crystal oscillator;

[0042] S102: Determine that the timing deviation of the external crystal oscillator reaches a deviation threshold, and switch the clock source of the controller from the external crystal oscillator to the internal crystal oscillator.

[0043] Exemplarily, the clothing processing device in the embodiment of the present disclosure represents a functional device that can process clothing, for example, it can realize one or more or all functions of cleaning, dehydrating, drying, softening, etc. of clothing. The process of clothing processing by the clothing processing device is generally controlled by the controller of the clothing processing device. For example, the controller can control the rotation of the motor, etc. Taking the cleaning of clothing as an example, the cleaning time can be a minutes, which requires the cleaning time to be timed. Generally, an external crystal oscillator and an internal crystal oscillator are configured in the clothing processing device. Both the external crystal oscillator and the internal crystal oscillator can output clock pulses at a certain frequency. The controller can use the clock pulses output by the external crystal oscillator or the internal crystal oscillator for timing, that is, the controller can use the external crystal oscillator or the internal crystal oscillator as the clock source for timing. Among them, the internal crystal oscillator is a crystal oscillator built into the controller chip of the clothing processing device, and the external crystal oscillator is a crystal oscillator independently set outside the chip. Based on the characteristics of the external crystal oscillator and the internal crystal oscillator, the accuracy of timing with the external crystal oscillator as the clock source is generally higher than the accuracy of timing with the internal crystal oscillator as the clock source. Therefore, the existing scheme generally only uses the external crystal oscillator as the clock source for timing.

[0044] However, in some possible scenarios, the external crystal oscillator, as a physical device, may not be able to output clock pulses of accurate frequency due to external or even internal factors, which may cause the controller to use the external crystal oscillator as the clock source to time inaccurately, resulting in the controller being unable to accurately control the clothing processing equipment to process clothes or even unable to operate. If not handled in a timely manner, it may cause user dissatisfaction and affect the user experience. Some existing solutions use a watchdog method to detect the external crystal oscillator. Specifically, when the controller is in sleep mode, the system cannot be awakened because the external crystal oscillator cannot work. At this time, the watchdog timer overflow interrupt is used for processing. When the watchdog overflows, other clock sources are switched. However, the middle solution is only applicable to the case where the external crystal oscillator fails completely.

[0045] Based on the above problems, the embodiment of the present disclosure provides a control method for a clothing processing device, which can be switched to an internal crystal oscillator in time after the controller uses an external crystal oscillator as a clock source and the timing deviation of the external crystal oscillator reaches a deviation threshold, and the internal crystal oscillator is used as the clock source for timing. The deviation threshold represents a value used to characterize the timing deviation, for example, it can be b, and if the value of the timing deviation is greater than or equal to b, it can represent that the timing deviation has reached the deviation threshold. In this scenario, since the timing deviation of the external crystal oscillator has reached the deviation threshold, it can be considered that it is completely incapable of timing, so the external crystal oscillator cannot be used as the clock source for timing, and the internal crystal oscillator can work normally and can be used as the clock source for timing. Therefore, after switching to the internal crystal oscillator and the controller uses the internal crystal oscillator as the clock source for timing, the controller can also relatively accurately control the operation of the clothing processing device. Compared with some solutions in the prior art, the control method for a clothing processing device provided by the embodiment of the present disclosure has a wider range of applications, and can be switched to the internal crystal oscillator in time after the timing deviation of the external crystal oscillator reaches the deviation threshold, which guarantees the user experience to a greater extent.

[0046] In some embodiments, determining that the timing deviation of the external crystal oscillator timing reaches the deviation threshold includes:

[0047] Obtaining a first count value within a preset time with an external crystal oscillator as a clock source and a second count value with an internal crystal oscillator as a clock source;

[0048] It is determined that a difference between the first count value and the second count value reaches a deviation threshold.

[0049] Exemplarily, for example, the first count value obtained within the preset time is p times, the second count value is q times, and the deviation threshold is r times. If the absolute value of the difference between p and q is greater than or equal to r, it can be determined that the difference between the first count value and the second count value reaches the deviation threshold. Conversely, if the absolute value of the difference between p and q is less than r, it can be determined that the difference between the first count value and the second count value does not reach the deviation threshold.

[0050] Through the above method, it can be more accurately determined whether the timing deviation of the external crystal oscillator timing reaches the deviation threshold.

[0051] In some embodiments, obtaining a first count value with an external crystal oscillator as a clock source within a preset time and a second count value with an internal crystal oscillator as a clock source includes:

[0052] Controlling the external crystal oscillator to be the clock source of the first timer, and the internal crystal oscillator to be the clock source of the second timer;

[0053] It is determined that the counting time of the second timer reaches a preset time, and a first counting value of the first timer and a second counting value of the second timer are obtained.

[0054] Exemplarily, the first timer and the second timer both represent functional devices that can perform timing and counting. As a possible implementation, the first timer and the second timer can be started simultaneously for counting, and when the counting time of the second timer reaches the preset time, the first count value corresponding to the first timer and the second count value corresponding to the second timer are counted. For example, the first count value of the first timer and the second count value of the second timer can be obtained after the counting time of the second timer reaches x seconds. The counting time corresponding to the first count value and the second count value is the same, and the second count value is a relatively accurate count value, so the first count value can be judged based on the second count value. If the difference between the second count value and the first count value reaches the deviation threshold, it can be said that the first count value is inaccurate, that is, the first count value and the second count value can be determined in the above manner, and then it is determined whether the difference between the second count value and the first count value reaches the deviation threshold.

[0055] In some embodiments, obtaining a first count value with an external crystal oscillator as a clock source within a preset time and a second count value with an internal crystal oscillator as a clock source includes:

[0056] Controlling the external crystal oscillator to be the clock source of the first timer, and the internal crystal oscillator to be the clock source of the second timer;

[0057] It is determined that the counting time of the first timer reaches a preset time, and a first counting value of the first timer and a second counting value of the second timer are obtained.

[0058] As another possible implementation, the first timer and the second timer may be started to count, and when the counting time of the first timer reaches the preset time, the first count value corresponding to the first timer and the second count value corresponding to the second timer may be counted. For example, the first count value of the first timer and the second count value of the second timer may be obtained after the counting time of the first timer reaches y seconds. The counting time corresponding to the first count value and the second count value is the same, and the second count value is a relatively accurate count value, so the first count value may be compared with the more accurate second count value. If the difference between the second count value and the first count value reaches the deviation threshold, it can be said that the first count value is inaccurate, that is, the first count value and the second count value may be determined in the above manner, and then it is determined whether the difference between the second count value and the first count value reaches the deviation threshold.

[0059] In some embodiments, it also includes:

[0060] It is determined that the difference between the first count value and the second count value does not reach the deviation threshold, and the count values ​​of the first timer and the second timer are cleared.

[0061] For example, if the difference between the first count value and the second count value reaches the deviation threshold, it can be shown that the external crystal oscillator can be used as a clock source to accurately time. At this time, the count values ​​of the first timer and the second timer can be cleared to zero, and the counting judgment can be re-performed, that is, it is possible to continuously determine whether the timing deviation of the external crystal oscillator reaches the deviation threshold. Based on the above scheme, if it is determined at any possible time point that the timing deviation of the external crystal oscillator reaches the deviation threshold, the external crystal oscillator can be switched to the internal crystal oscillator, and the internal crystal oscillator is used as the clock source for timing, so as to ensure that the controller can control the normal operation of the clothing processing device and ensure the user experience.

[0062] In some embodiments, the internal crystal oscillator includes an internal low-speed crystal oscillator and an internal high-speed crystal oscillator;

[0063] Acquiring a second count value with the internal crystal oscillator as the clock source includes: acquiring a second count value with the internal low-speed crystal oscillator as the clock source;

[0064] Switching the controller's clock source from an external crystal oscillator to an internal crystal oscillator includes:

[0065] Switch the controller's clock source from an external crystal oscillator to an internal high-speed crystal oscillator;

[0066] Among them, the operating frequency of the internal low-speed crystal oscillator is lower than the operating frequency of the internal high-speed crystal oscillator.

[0067] Exemplarily, the internal crystal oscillator may include an internal high-speed crystal oscillator and an internal low-speed crystal oscillator, and the difference between the internal high-speed crystal oscillator and the internal low-speed crystal oscillator is the operating frequency. The disclosed embodiment involves three types of crystal oscillators, namely, an external crystal oscillator, an internal high-speed crystal oscillator, and an internal low-speed crystal oscillator. In terms of the accuracy of timing as a clock source, the accuracy of the external crystal oscillator is greater than the accuracy of the internal high-speed crystal oscillator, and the accuracy of the external crystal oscillator is also greater than the accuracy of the internal high-speed crystal oscillator.

[0068] In the process of determining the second count value, since only the second timer is needed, it does not need an excessively high frequency of the internal crystal oscillator, and the internal low-speed crystal oscillator can be used as the clock source for counting. The second count value can be determined by the internal low-speed crystal oscillator, and then it is determined that the count deviation of the external crystal oscillator reaches the deviation threshold. In the process of switching the clock source of the controller from the external crystal oscillator to the internal crystal oscillator, since the controller needs to use this as the clock source to control the operation of the clothing processing device, a higher frequency is required, and the external crystal oscillator can be switched to the internal high-speed crystal oscillator to better control the operation of the clothing processing device.

[0069] Based on the above scheme, the embodiment of the present disclosure can reduce the loss of electric energy and can perform timing more accurately while ensuring that it can accurately determine whether the external crystal oscillator can be used as a clock source to more accurately time.

[0070] In some embodiments, the internal crystal oscillator comprises an internal high-speed crystal oscillator;

[0071] Acquiring a second count value with the internal crystal oscillator as the clock source includes: acquiring a second count value with the internal high-speed crystal oscillator as the clock source;

[0072] Switching the controller's clock source from an external crystal oscillator to an internal crystal oscillator includes:

[0073] Switch the controller's clock source from an external crystal oscillator to an internal high-speed crystal oscillator.

[0074] For example, in some possible scenarios, only an internal high-speed crystal oscillator may be provided in the clothing processing device, or the internal low-speed crystal oscillator may not be used due to some reasons. In this scenario, the embodiment of the present disclosure can use the internal high-speed crystal oscillator as the clock source to count and determine the second count value, and then determine that the count deviation of the external crystal oscillator reaches the deviation threshold. In the process of switching the external crystal oscillator, the external crystal oscillator can also be switched to the internal high-speed crystal oscillator, and the internal high-speed crystal oscillator can be used as the clock source for timing to more accurately control the operation of the clothing processing device.
