[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0026] It should be understood that when an element (such as a layer, film, region, or substrate) is described as being "on" another element, the element may be directly on the other element or intervening elements may be present. Moreover, in the specification and claims, when it is described that an element is "connected to" another element, the element may be "directly connected to" the other element or "connected to" the other element through a third element.

[0027] As mentioned in the background technology, in the prior art, when many electrical appliances are operating at the same time, turning on the air conditioner without reducing the power of other running appliances may cause the circuit to exceed the tolerance value and cause repeated tripping, thereby affecting the user's comfort. In order to solve the above problem, a typical embodiment of the present application provides an air conditioner control method and device, an air conditioner, a processor and an electronic device.

[0028] According to an embodiment of the present application, a method for controlling an air conditioner is provided.

[0029] Figure 1 This is a flow chart of a method for controlling an air conditioner according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0030] Step S101: When it is detected that the air conditioner is started, it is determined whether the air conditioner meets the power limit condition. If the air conditioner meets the power limit condition, the air conditioner is controlled to enter the power limit mode.

[0031] Step S102: obtaining a plurality of operating parameters of the air conditioner in the power limiting mode.

[0032] In step S103 , control conditions that the air conditioner meets are determined based on the plurality of operating parameters, and a control strategy corresponding to the control conditions is determined based on the control conditions.

[0033] Step S104: Control the operation of the air conditioner according to the control strategy.

[0034] The present application provides a new power mode for an air conditioner. When a user has many household appliances running and the air conditioner cannot be used normally after being turned on according to normal actual needs, the power limiting condition is used to determine whether the air conditioner needs to enter the power limiting mode. In the power limiting mode, the control conditions that the air conditioner meets are determined by the operating parameters of the air conditioner, and the control strategy of the air conditioner is determined to ensure that the air conditioner can operate at a lower operating power and meet the basic usage needs of the user, thereby preventing the air conditioner or other appliances from being completely unusable, resulting in a reduction in user experience and comfort.

[0035] As described above, when it is detected that the air conditioner is started, whether the air conditioner meets the power limit condition is determined, including: obtaining a target cumulative value corresponding to the air conditioner, wherein the target cumulative value is the cumulative number of times the air conditioner was not shut down normally and a power outage occurred during the historical operation of the air conditioner before the current startup; determining whether the target cumulative value is greater than or equal to a preset threshold; and determining that the air conditioner meets the power limit condition when the target cumulative value is greater than or equal to the preset threshold.

[0036] Specifically, after the air conditioner is started, the target cumulative value M is first detected after power is turned on. If M ≥ 2, the air conditioner enters the power limit control mode after startup. Whether or not the power limit mode is entered does not affect the subsequent detection process. In this application, in a specific embodiment, the value of M is temporarily set to 2. Considering that the user may directly turn off the power, in order to prevent the power limit mode from being entered after a single power outage, the value is preferably not set to less than 1.

[0037] Furthermore, after the air conditioner is powered on, there are two subsequent operations: one is to start the air conditioner, and the other is to power it off. Only after the air conditioner is powered on and the load begins to run will the M value be increased by 1. This is because the air conditioner has a memory function. If the power is suddenly cut off last time, it will default to power on after powering on again. If the M value is increased by 1 before the load is turned on, it cannot be cleared by turning the air conditioner on and off. Moreover, if the circuit is overpowered when the air conditioner is turned on and the load is not started, it means that the circuit conditions at this time do not support the operation of the air conditioner at all, and the air conditioner will no longer be considered to enter the power limit mode.

[0038] Furthermore, after powering on or activating the load, there are two subsequent operations: shutdown and power-off. When the shutdown operation is executed, the M value is processed as -1, indicating that the air conditioner's workflow is complete without any power outages. If the power is directly cut off, no processing is performed on the M value, and the M value is accumulated once. After the load is activated, the unit updates the current power value P in real time and assigns it to the variable Pn in the memory chip, which serves as a reference when entering power-limiting mode.

[0039] After a certain period of time, T, after the air conditioner loses power, the M value is reset. This operation takes into account that if a circuit overpower occurs, the user may promptly repair it to restore normal operation of the air conditioner. If the user increases the available load of the air conditioner by reducing other electrical appliances, the M value can be reset by manually turning the air conditioner on and off. The T value can be set based on actual experience.

[0040] In an optional embodiment, based on multiple operating parameters, the control conditions that the air conditioner meets are determined, and the control strategy corresponding to the control conditions is determined based on the control conditions, including: obtaining the current power and the previous power of the air conditioner, wherein the previous power is the operating power corresponding to the air conditioner before the previous power-off operation; determining the target power of the air conditioner based on the previous power; obtaining a first preset margin power; calculating the difference between the target power and the first preset margin power to obtain a first target difference power; and determining the control conditions that the air conditioner meets and the control strategy corresponding to the control conditions based on the current power and the first target difference power.

[0041] As mentioned above, when the air conditioner is powered on and detects M ≥ 2, it enters power-limited mode. Upon entering this mode, the power Pn recorded before the last power outage in the memory chip is retrieved and then calculated with the second preset margin power Pd to obtain the target power Pm for this power-limited mode. The process is executed cyclically, and various judgment condition parameters, such as current power P, current frequency F, and target frequency Fm, are collected and calculated in real time. During each loop, only the value within the current loop is used for logical judgment. These parameters are used to determine the corresponding control strategy for the air conditioner.

[0042] Furthermore, a first target power difference ΔP=P between the target power and the first preset margin power is calculated. m -P1, determines the control strategy corresponding to the air conditioner based on the relationship between the first target power difference and the current power.

[0043] Among them, based on the current power and the first target difference power, the control conditions that the air conditioner meets and the control strategy corresponding to the control conditions are determined, including: determining the size relationship between the current power and the first target difference power; when the current power is less than the first target difference power, determining that the air conditioner meets the first control condition, and determining that the control strategy used to control the air conditioner is the first control strategy, wherein the first control strategy is a control strategy for operating the air conditioner according to the actual power required by the air conditioner unit.

[0044] As mentioned above, if P < ΔP, each load is controlled according to the unit's own needs. At this time, the unit power P has not reached the limit value, indicating that it is still some distance away from the target power Pm. Therefore, it is operated according to the unit's own needs to meet the cooling or heating requirements as much as possible. In this step, P is the floating margin calculated proportionally from the power Pn recorded at the time of the last power outage (or a preset fixed margin). The floating margin can determine the power adjustment size based on the actual power usage environment and is more in line with actual conditions. The fixed margin can be pre-set and has higher reliability. However, if the available power reserved for the air conditioner is not large, the user experience will be poor. The specific setting can be determined according to actual conditions.

[0045] In an optional embodiment, determining the control condition that the air conditioner complies with and the control strategy corresponding to the control condition based on the current power and a first target power difference includes: determining the magnitude relationship between the current power and the first target power difference; when the current power is greater than or equal to the first target power difference, determining the magnitude relationship between the first target power difference, the target power, and the current power; and determining the control condition that the air conditioner complies with and the control strategy corresponding to the control condition based on the magnitude relationship. Determining the control condition that the air conditioner complies with and the control strategy corresponding to the control condition based on the magnitude relationship includes: when the current power is greater than or equal to the first target power difference and the current power is less than the target power, determining that the air conditioner complies with a second control condition and determining the control strategy for controlling the air conditioner to be a second control strategy, wherein the second control strategy is a control strategy that changes the target operating frequency of the air conditioner to the current operating frequency of the air conditioner. Determining the control condition that the air conditioner complies with and the control strategy corresponding to the control condition based on the magnitude relationship includes: when the current power is greater than or equal to the target power, determining that the air conditioner complies with a third control condition and determining the strategy corresponding to the third control condition to be a third control strategy, wherein the third control strategy is a control strategy that reduces the current operating frequency of the air conditioner by a preset frequency value and reduces the target frequency of the air conditioner by a preset frequency value.

[0046] As mentioned above, if P≥Pm-P1, the current power P is further judged against the target power Pm. If P≥Pm-P1, it is considered that the current power P is close to or exceeds the target power Pm, and the load needs to be restricted. The specific restriction method is determined by comparing the current power P with the target power Pm, as follows:

[0047] If ΔP≤P<Pm, the current unit power is considered close to the target power Pm. The current frequency value F is then assigned to the target frequency value Fm. By replacing the target frequency with the current frequency, the power is maintained at the current power level. However, in general, after the frequency stabilizes, the power may still fluctuate depending on the system load, and this power change ΔP2 is allowed.

[0048]

[0049] The calculated result is rounded up. Because the power has exceeded the target power, the frequency must be reduced to prevent it from exceeding the protection power value. By calculating ΔF, we can approximate the power per hertz represented by the current load. By further reducing the frequency corresponding to the power value exceeding the target power value, we can minimize the power to Pm, ensuring the optimal user experience while still being able to operate.

[0050] To illustrate the above control strategy, assume a circuit can only handle 3000W of power, and other appliances already occupy 2000W, leaving only 1000W for the air conditioner. When the user turns on the air conditioner, no loads are running, and the power consumption is extremely low. If the power is cut off at this time, the overpowered appliances are not considered to be caused by the air conditioner, and the fault count is not increased. Furthermore, since the air conditioner has a memory function that defaults to power on after power is restored, the count is not accumulated until the load is turned on. If manual reset is required, the count can be reset by repeatedly shutting down the air conditioner before turning on the load. Alternatively, if the air conditioner is powered off for a period of time, the circuit is assumed to be under maintenance, or other appliances are turned off, and the count is reset to zero.

[0051] When entering power limit mode, the air conditioner calculates Pm = 1000W - Pd. For example, if Pd is 200W, Pm = 800W. The air conditioner initially operates according to demand without restrictions, such as a target frequency (Fm) of 70Hz. During operation, the current power is compared with the power limit (Pm - P1) in real time, setting it to 800W - 100W = 700W. For example, when P = 700W and F = 62Hz, upon reaching this threshold, the frequency is fixed to the current value, Fm = 62Hz, to prevent power from increasing. If power rises above the Pm limit due to factors such as ambient temperature, the frequency is reduced proportionally. For example, if P = 810W, then ΔF = (810 - 800) * 62 / 810 ≈ 1Hz, and Fm = 62 - 1 = 61Hz. This control method ensures that power approaches the target value as closely as possible.

[0052] The present application provides an air conditioner control method that detects the impact of circuit overpower on the unit through power on / off, memory functions, etc., and then allows the unit to limit operation to the target power and operating frequency based on the air conditioner operating power before power failure, memory fault causes and times, etc., to avoid circuit protection caused by excessive power.

[0053] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
