Description

Technical Field

[0001] This invention relates to the field of air conditioning system technology, and in particular to a control method, device and storage medium for an air conditioner. Background Technology

[0002] In modern life, air conditioning has become an indispensable part of family life. Air conditioning is used to adjust the indoor temperature to improve the comfort of the indoor environment.

[0003] During peak electricity consumption periods in summer or winter, or during power grid maintenance, air conditioners may experience power outages. After power is restored, the air conditioner may continue operating as it did before the outage or stop operating altogether. However, during the period of power outage, the indoor temperature has often changed. Simply repeating the previous operating state will not allow the indoor temperature to reach the original set temperature, resulting in the air conditioner failing to meet usage requirements after a power outage and restarting. Summary of the Invention

[0005] This invention provides a control method for an air conditioner, comprising the following steps:

[0006] Determine whether the air conditioner has been restarted after a power outage;

[0007] In the case of the air conditioner restarting after a power outage, the real-time ambient temperature, the original target temperature of the air conditioner before the power outage, and the original operating parameters are obtained.

[0008] Based on the temperature difference between the real-time ambient temperature and the original target temperature, the operating parameters of the air conditioner are adjusted according to the original operating parameters.

[0009] According to the control method for an air conditioner provided by the present invention, the step of adjusting the operating parameters of the air conditioner based on the temperature difference between the real-time ambient temperature and the original target temperature, and according to the original operating parameters, includes:

[0010] If the temperature difference is greater than the preset difference, the operating parameters are adjusted based on the original operating parameters according to the temperature difference.

[0011] If the temperature difference is less than the preset difference, the air conditioner will operate with the original operating parameters.

[0012] According to the control method for an air conditioner provided by the present invention, the operating parameters include operating fan speed and operating frequency.

[0013] According to the control method for an air conditioner provided by the present invention, before the steps of obtaining the real-time ambient temperature, the original target temperature of the air conditioner before the power outage, and the original operating parameters, the method further includes:

[0014] Get the status of people within the preset space;

[0015] Based on the personnel status, the system controls and acquires the real-time ambient temperature, the original target temperature, and the original operating parameters.

[0016] According to the control method for an air conditioner provided by the present invention, the steps of controlling the acquisition of the real-time ambient temperature, the original target temperature, and the original operating parameters based on the personnel status include:

[0017] If the presence of personnel is detected in the preset space, the real-time ambient temperature, the original target temperature, and the original operating parameters are acquired.

[0018] If no one is detected in the preset space, the air conditioner will be turned off.

[0019] According to the control method for an air conditioner provided by the present invention, the step of controlling the air conditioner to shut down when no one is detected in the preset space further includes:

[0020] If no one is detected in the preset space, the air conditioner is controlled to enter standby mode, and the duration of the standby mode is recorded.

[0021] When the duration exceeds the first preset duration, the air conditioner is controlled to turn off.

[0022] According to the control method for an air conditioner provided by the present invention, the step of adjusting the operating parameters of the air conditioner based on the original operating parameters further includes:

[0023] Obtain the power outage duration of the air conditioner;

[0024] The operating parameters are adjusted according to the duration of the power outage.

[0025] According to the control method for an air conditioner provided by the present invention, the step of adjusting the operating parameters based on the power outage duration includes:

[0026] If the power outage duration exceeds the second preset duration, the air conditioner is controlled to enter standby mode;

[0027] If the power outage duration is less than the second preset duration, the operating parameters are adjusted.

[0028] The present invention also provides a control device for an air conditioner, including a memory, a processor, and a control program for an air conditioning system stored in the memory and executable on the processor, wherein the control program for the air conditioner is configured to implement the control method for the air conditioner according to any of the preceding claims.

At this time, the real-time ambient temperature, the original target temperature of the air conditioner before the power outage, and the original operating parameters are obtained. The real-time ambient temperature is compared with the original target temperature. Based on the temperature difference between the two, it is determined whether the air conditioner can complete the task of reaching the original target temperature with the original operating parameters. Then, the original operating parameters are adjusted according to the actual situation so that the air conditioner can still restore the temperature to the originally set target temperature in a timely manner after a power outage and restart.

[0033] Figure 2 This is a schematic block diagram of an embodiment of the control device provided by the present invention. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0035] Please see Figure 1 The present invention provides a control method for an air conditioner, comprising the following steps:

[0036] S10. Determine whether the air conditioner has been restarted after a power outage;

[0037] S20. In the case of the air conditioner restarting after a power outage, obtain the real-time ambient temperature, the original target temperature of the air conditioner before the power outage, and the original operating parameters.

[0038] S30. Based on the temperature difference between the real-time ambient temperature and the original target temperature, adjust the operating parameters of the air conditioner according to the original operating parameters.

[0039] In the air conditioner control method provided by the present invention, when the air conditioner is started, it is determined whether the air conditioner is restarting after a power outage. In the case of a power outage, after the air conditioner restarts, the indoor temperature may fluctuate significantly, and the original operating parameters may not be sufficient to meet the temperature control requirements. At this time, the real-time ambient temperature, the original target temperature of the air conditioner before the power outage, and the original operating parameters are obtained. The real-time ambient temperature is compared with the original target temperature. Based on the temperature difference between the two, it is determined whether the air conditioner can complete the task of reaching the original target temperature with the original operating parameters. Then, the original operating parameters are adjusted according to the actual situation so that the air conditioner can still restore the temperature to the originally set target temperature in a timely manner after a power outage and restart.

[0040] It should be noted that step S10 can be implemented in various ways. For example, it can determine whether the air conditioner received a shutdown command before the last shutdown. If a shutdown command was received, it is a normal shutdown; if no shutdown command was received, it is a power outage restart. As long as it can detect whether the air conditioner is restarting after a power outage, no specific limitation is made here.

[0041] Furthermore, step S30 includes:

[0042] S31. If the temperature difference is greater than the preset difference, adjust the operating parameters based on the original operating parameters according to the temperature difference.

[0043] In this embodiment, when the temperature difference is greater than the preset difference, it indicates that the indoor ambient temperature has fluctuated significantly and the original temperature control effect in the room has disappeared. If the original operating parameters are maintained at this time, it will result in the inability to achieve the original target or a longer time to achieve it. In this case, the original operating parameters are directly adjusted according to the temperature difference to improve the working effect and efficiency of the air conditioner.

[0044] S32. If the temperature difference is less than the preset difference, the air conditioner is operated with the original operating parameters.

[0045] In this embodiment, if the temperature difference is less than the preset difference, it indicates that the indoor ambient temperature has not dropped too much. At this time, even if the original operating parameters of the air conditioner are maintained, the current indoor temperature can be maintained. Therefore, the air conditioner is operated directly with the original operating parameters.

[0046] Specifically, the operating parameters include operating wind speed and operating frequency.

[0047] Based on the above-described control method for air conditioners, the present invention provides a specific embodiment.

[0048] In this embodiment, a first temperature difference threshold and a second temperature difference threshold that increase sequentially are also included.

[0049] When the temperature difference is between the preset difference and the first temperature difference threshold, the operating wind speed is kept constant, and the operating frequency is controlled to enter the PID frequency modulation mode, wherein the PID frequency modulation is to automatically adjust the frequency according to the system error and actual parameters.

[0050] When the temperature difference is between the first temperature difference threshold and the second temperature difference threshold, the operating wind speed is adjusted to a medium wind speed, and the operating frequency is controlled to enter PID frequency modulation mode.

[0051] When the temperature difference is greater than the second temperature difference threshold, the operating wind speed and the operating frequency are adjusted to the maximum wind speed and maximum frequency that the air conditioner can operate normally.

[0052] On the other hand, step S20 includes the following prior to:

[0053] S021. Obtain the status of personnel within the preset space;

[0054] S022. Based on the personnel status, control the acquisition of the real-time ambient temperature, the original target temperature, and the original operating parameters.

[0055] In this embodiment, after the air conditioner is powered off, the state of the people in the indoor space will change, and there will be a situation where the air conditioner is no longer needed to control the temperature. At this time, after the air conditioner is powered on and started, there is no need to continue the temperature control work. Before obtaining the real-time ambient temperature and other parameters, the state of the people in the preset space is first determined, and the real-time ambient temperature, the original target temperature and the original operating parameters are obtained according to the state of the people.

[0056] It should be noted that the personnel status can be implemented in various ways. For example, it can be monitored by infrared devices to detect the personnel's resting state. When the personnel are in a resting state, the real-time ambient temperature and other parameters are no longer acquired, and no further operation is performed on the air conditioner. Specifically, in this embodiment, the personnel status includes whether or not they are within the preset space. Step S022 includes:

[0057] S0221. When the presence of personnel is detected in the preset space, acquire the real-time ambient temperature, the original target temperature, and the original operating parameters.

[0058] S0222. If no one is detected in the preset space, control the air conditioner to turn off.

[0059] In the event of a power outage, people may leave the room due to temperature changes. If the air conditioner is turned on immediately after the power is restored, the air conditioner will work ineffectively and waste power. In this embodiment, when there are no people in the preset space, the air conditioner is turned off. When there are people in the preset space, the real-time ambient temperature, the original target temperature, and the original operating parameters are obtained, and then the original operating parameters are adjusted accordingly.

[0060] It should be noted that there are multiple ways to determine whether the person is in the preset space. For example, the presence of the person in the space can be determined by a radar device or an infrared device. In this embodiment, as long as the presence status of the person in the preset space can be obtained, no specific limitation is made here.

[0061] Furthermore, step S0222 also includes:

[0062] S02221. If no person is detected in the preset space, control the air conditioner to enter standby mode and record the duration of the standby mode;

[0063] S02222: When the duration exceeds the first preset duration, control the air conditioner to turn off.

[0064] In this embodiment, when there are no people in the preset space, if people sense an incoming call, they may return to the room. In this case, instead of directly turning off the air conditioner, the air conditioner is put into standby mode so that it can be controlled again when people enter, reducing the number of times the air conditioner is turned on and off and saving energy.

[0065] It should be noted that when the air conditioner is in the standby state, the air conditioner is in the on state, and all components are in the activated and preheating state so as to respond to adjustment control commands at any time.

[0066] Furthermore, the control method for the air conditioner also includes:

[0067] When the duration is within the first preset time period, and personnel are detected in the preset space, the real-time ambient temperature, the original target temperature, and the original operating parameters are acquired. In this embodiment, since the air conditioner is in standby mode, it can quickly enter the temperature control mode. When personnel are detected to have returned to the preset space within the first preset time period, the real-time ambient temperature, the original target temperature, and the original operating parameters are acquired, and subsequent temperature control is performed to facilitate continued automatic control after a power outage.

[0068] Furthermore, in the technical solution provided by this invention, step S30 further includes:

[0069] S31. Obtain the power outage duration of the air conditioner;

[0070] S32. Adjust the operating parameters according to the power outage duration.

[0071] In this embodiment, before adjusting the original operating parameters, it is also necessary to obtain the power outage duration of the air conditioner. As the power outage time passes, the surrounding environment and the user's demand for ambient temperature will not be exactly the same. Incorporating the power outage duration into the adjustment process of the original operating parameters makes the adjustment of the air conditioner more intelligent and accurate, avoiding the situation where the previous operating plan is simply executed after the power outage is restarted, which is inconsistent with the actual situation.

[0072] It should be noted that there are multiple ways to obtain the power outage duration of the air conditioner. For example, a power outage timer can be installed in the air conditioner. When AC power cannot be received, the timer starts and continues until power is restored. In this embodiment, as long as the power outage duration of the air conditioner can be obtained, no specific restrictions are imposed.

[0073] Specifically, step S32 includes:

[0074] S321. If the power outage duration is longer than the second preset duration, control the air conditioner to enter standby mode;

[0075] In this embodiment, if the power outage duration exceeds the second preset duration, the external environment may have undergone significant changes, and the original settings may no longer meet the needs. Furthermore, due to the excessively long power outage duration of the air conditioner, regardless of the original state of the room, the settings need to be reset to meet the needs of the occupants again. In this case, after the air conditioner is powered on again, the original operating parameters are not adjusted, but the air conditioner is directly controlled to enter standby mode to facilitate subsequent temperature control.

[0076] S322. If the power outage duration is less than the second preset duration, adjust the operating parameters.

[0077] In this embodiment, only when the power outage duration is less than the second preset duration can it be proven that the original target temperature can still meet the user's needs, and adjustments based on the original operating parameters can be made. In this case, the original operating parameters can continue to be adjusted.

[0078] It should be noted that there are various factors that can be used to set the second preset duration. It can be set according to the rate of temperature loss and the frequency of temperature changes in different seasons. In this embodiment, the second preset duration varies depending on the season. In summer, the second preset duration is 30 minutes; in winter, the second preset duration is 2 to 3 hours.

[0079] Furthermore, step S321 also includes: obtaining the duration of the standby state; and controlling the air conditioner to turn off after the duration exceeds a third preset duration.

[0080] This invention also provides a controller. Figure 2 A schematic diagram of the physical structure of the controller is shown below, such as... Figure 2 As shown, the controller may include a processor 1001, a communications interface 1002, a memory 1003, and a communications bus 1004, wherein the processor 1001, the communications interface 1002, and the memory 1003 communicate with each other through the communications bus 1004.

The aforementioned storage medium includes various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.

[0083] It should be noted that the controller in this embodiment can be a server, a PC, or other devices, as long as its structure includes the following: Figure 2 The processor 1001, communication interface 1002, memory 1003, and communication bus 1004 shown are configured to communicate with each other via the communication bus 1004. The processor 1001 can call logical instructions in the memory 1003 to execute the aforementioned method. This embodiment does not limit the specific implementation of the controller.
