[0046] Summary of the technical solution of the present invention:

[0047] The present invention mainly determines the electromagnetic interference status of the environment where the air conditioner is located accurately, and then in order to prevent the electromagnetic interference from affecting the memory data in the wire controller or the central control panel, determines the target memory frequency of the corresponding air conditioner according to different interference values, and finally updates the original memory frequency to the determined target memory frequency, so that the internal memory in the air conditioner can maintain the stability of the memory data, thereby making the wire controller or the central control panel control the air conditioner more stable and accurate according to the memory data. The core of the present invention is to dynamically reduce the frequency of the internal memory according to the prediction of the electromagnetic interference in the environment where the air conditioner is located, so as to ensure the stability of the memory data in the air conditioner, thereby ensuring the stability and reliability of the air conditioner control.

[0048] An embodiment of the present invention provides an air conditioner.

[0049] like Figure 1 As shown, Figure 1 It is a structural diagram of the hardware operating environment of the air conditioner involved in the embodiment of the present invention.

[0050] like Figure 1As shown, the air conditioner may include: a processor 1001, such as a CPU, a network interface 1004, a user interface 1003, a memory 1005, and a communication bus 1002. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display (Display), an input unit such as a control panel, and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a WIFI interface). The memory 1005 may be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001. The memory 1005 as a computer storage medium may include a memory dynamic frequency reduction program.

[0051] Those skilled in the art will understand that Figure 1 The hardware structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0052] Continue to refer to Figure 1 , Figure 1 The memory 1005 as a computer-readable storage medium may include an operating system, a user interface module, a network communication module, and a memory dynamic frequency reduction program.

[0053] exist Figure 1 In the embodiment, the network communication module is mainly used to connect to the server and perform data communication with the server; and the processor 1001 can call the memory dynamic frequency reduction program stored in the memory 1005 and execute the steps in the following embodiments.

[0054] Based on the hardware structure of the controller described above, various embodiments of the memory dynamic frequency reduction method of the present invention are proposed.

[0055] An embodiment of the present invention provides a memory dynamic frequency reduction method.

[0056] Please refer to Figure 2 , Figure 2 1 is a flow chart of a first embodiment of a method for dynamic memory frequency reduction according to the present invention; in the first embodiment of the present invention, the method for dynamic memory frequency reduction comprises the following steps:

[0057] Step S10, during the operation of the air conditioner, determining the current interference value of the air conditioner;

[0058] The air conditioner internal communication control method in this implementation is applied to a wire controller or a central control panel, wherein the wire controller refers to a device that has the ability to control the air conditioner at home, and is characterized in that it is connected to the air conditioner internal unit by wire, and the wired connection method can be a two-core non-polarity, 485, and other air conditioner control terminal. Another feature of the wire controller is that the wire controller is equipped with an operating system, a touch screen, a voice recognition module, and other features, wherein the touch screen includes but is not limited to an LCD (Liquid Crystal Display) display and an OLED (Organic Light-Emitting Diode) display. The central control panel refers to a control terminal that has the ability to control the wire controller and also has the ability to manage, control, and display the status of home smart devices. It also has the wire controller type wired method to connect to the air conditioner. It is also equipped with an operating system, and also includes features such as a touch screen and a voice recognition module.

[0059] Since the central control panel has all the functions of a wired controller, it can also be regarded as a kind of wired controller. In the following text, for the convenience of description, the term "wired controller" is used to refer to the wired controller and central control panel in the general sense mentioned above.

[0060] As for the specific connection relationship of the wire controller in the air conditioner, it is mainly connected to the indoor unit of the air conditioner for communication. For the connection relationship between the two, please refer to Figure 7 , Figure 7 FIG. 1 is a schematic diagram of the multi-terminal connection relationship of the air conditioner involved in the internal communication control method of the air conditioner of the present invention, such as Figure 7 As shown, taking set 1 as an example, the air conditioner outdoor unit is connected to the air conditioner indoor unit by communication, and the wire controller is connected to the air conditioner indoor unit by communication. In addition, if there is a central control panel, it is also connected to the air conditioner indoor unit by communication. In addition, if it is needed, the wire controller can also be set to communicate with the outdoor unit so that the user can directly monitor or control the operation of the outdoor unit indoors, which is not limited here.

[0061] When the air conditioner is operating in cooling, heating, defrosting, fresh air and other modes or functions, it is necessary to determine the electromagnetic interference of the environment in which the air conditioner is located, and to digitize the electromagnetic interference into the current interference value in order to accurately grasp the degree of electromagnetic interference. It should be noted that the causes of electromagnetic interference here are various, such as the interference generated by various motors including various fans in the air conditioner during operation, the electromagnetic interference generated by the operation of the compressor, and the electromagnetic interference generated by the operation of other equipment in the air conditioner. In addition to the interference caused by the operation of the air conditioner itself to the wire controller, it also includes electromagnetic interference generated by the operation of other adjacent or similar air conditioners, such as Figure 7If the air conditioner set 2 is arranged adjacent to the set 1, electromagnetic interference will be generated between them. In addition, there are various other external electromagnetic interferences, which will not be listed here one by one.

[0062] In an environment with electromagnetic interference, it will interfere with the wire controller's reception of various operating data signals from the air conditioner's indoor unit (it can also be the air conditioner's outdoor unit, only the air conditioner's indoor unit is used for explanation here) and various control signals output to the air conditioner's indoor unit. In other words, the wire controller's control of the air conditioner's indoor unit is interfered, resulting in abnormal control of the air conditioner by the wire controller.

[0063] How to determine the current interference value of the air conditioner can be determined by looking up a table or calculating according to various operating parameters of the air conditioner. The operating parameters here include but are not limited to: set temperature, set wind speed, operation mode (cooling, heating, fresh air, defrosting, energy saving, etc.), indoor fan gear or speed, outdoor fan gear or speed, air outlet temperature, indoor temperature, indoor humidity, outdoor heat exchanger temperature, indoor heat exchanger temperature, compressor temperature, compressor frequency, etc.

[0064] Please refer to Figure 3 In one embodiment, the step S10 includes:

[0065] Step S11, obtaining current preset operating parameters during the operation of the air conditioner;

[0066] Step S12, according to the acquired preset operating parameters, calculate or look up the table to obtain the current interference value of the air conditioner.

[0067] In this embodiment, the preset operating parameters may be the above-mentioned operating condition parameters, and the preset operating parameters may be divided into two categories: user-set parameters and air conditioner self-adjusting parameters. The user-set parameters may include operating parameters such as set temperature, set wind speed, and operating mode, and the air conditioner self-adjusting parameters may include operating parameters such as indoor fan gear or speed, outdoor fan gear or speed, outlet temperature, indoor temperature, indoor humidity, outdoor heat exchanger temperature, indoor heat exchanger temperature, compressor temperature, and compressor frequency. Among them, the difference between the user-set parameters and the air conditioner self-adjusting parameters lies in whether the operating parameters are parameters set by the user or operating condition parameters required for the air conditioner to perform adaptive adjustment.

[0068] After the current preset operating parameters are determined, the current interference value of the air conditioner can be calculated by using one or more parameters of these preset operating parameters. For the calculation method, the preset operating parameters can be input into the preset interference calculation function to accurately obtain the current interference value. The current interference value can also be obtained by looking up the table by determining the mapping relationship between one or more preset operating parameters and the current interference value. It should be noted that both the function required for calculation and the table required to be queried are determined on the basis of a large number of experiments. In addition, the corresponding target mapping table can be determined according to the parameter type of the preset operating parameters (user-set parameters and air conditioner self-adjustment parameters), and then the current interference value of the air conditioner can be determined by looking up the table according to different target mapping tables, so as to specifically distinguish different types of operating parameters and determine different current interference values, so as to make different treatments according to whether there is a user operating the wire controller to set each user-set parameter, so as to meet the memory frequency control in different scenarios and reduce unnecessary troubles to users.

[0069] In one embodiment, the step S12, calculating and obtaining the current interference value of the air conditioner according to the acquired preset operating parameters, includes:

[0070] Step a, detecting an input signal input into the wire controller corresponding to the preset operating parameter, and determining an actual signal amplitude of the input signal and a predicted signal amplitude corresponding to the preset operating parameter;

[0071] Step b, calculating the difference between the actual signal amplitude and the predicted signal amplitude to determine the current interference value of the air conditioner.

[0072] Different preset operating parameters will generate different input signals. In other words, the input signal input into the wire controller varies with the various operating parameters of the air conditioner, and the operating parameters here include not only the number of operating parameters, but also the specific working condition values ​​of the operating parameters. Detecting the input signal into the wire controller corresponding to the preset operating parameters is to detect the signal actually input into the wire controller, determine the actual signal amplitude of the input signal, and also need to determine the predicted signal amplitude corresponding to the preset operating parameters. The predicted signal amplitude corresponding to the preset operating parameters refers to the signal amplitude of the input signal corresponding to the preset operating parameters in an environment without electromagnetic interference, which can also be considered as the theoretical signal amplitude of the theoretical input signal.

[0073] In an environment with electromagnetic interference, the actual signal amplitude is greater than the predicted signal amplitude. The difference between the actual signal amplitude and the predicted signal amplitude is obtained by subtracting the actual signal amplitude from the predicted signal amplitude. This difference can be used as the current interference value of the air conditioner to more accurately and reliably reflect the impact of electromagnetic interference on the wire controller. The larger the difference, the larger the actual signal amplitude is compared to the predicted signal amplitude, which essentially reflects the greater the degree of electromagnetic interference.

[0074] In one embodiment, the step S10 includes:

[0075] Step c, during the operation of the air conditioner, determining the current interference value of the air conditioner at intervals of a preset time; or,

[0076] Step d: during the operation of the air conditioner, when a parameter setting operation is received or the working state of the air conditioner changes, the current interference value of the air conditioner is determined.

[0077] During the operation of the air conditioner, the current interference value of the air conditioner can be obtained and determined by the air conditioner in real time, or the current interference value of the air conditioner can be determined at preset intervals, so that the electromagnetic interference status of the environment where the air conditioner is located can be grasped in a timely manner. The preset time can be set according to actual needs, such as 1 minute, 2 minutes, etc., and there is no limitation here.

[0078] During the operation of the air conditioner, when the wire controller receives the parameter setting operation performed by the user, that is, when the user uses the wire controller to control the air conditioner, the current interference value of the air conditioner can be obtained and determined, or when the working state of the air conditioner changes, the current interference value of the air conditioner can be obtained and determined. Here, the working state of the air conditioner changes when the change amount of any preset operating parameter is greater than the corresponding preset change threshold, and it can be considered that the working state has changed. For example, the cooling temperature is 27°C at the beginning and then changes to 22°C. The preset change threshold is 4°C, then it is considered that the working state has changed. The change in the working state of the air conditioner can also be understood as a change in the operating mode, such as the conversion of the fresh air mode to the cooling mode. Considering that the electromagnetic interference of the air conditioner usually changes when various working conditions change through the parameter setting operation or the working state of the air conditioner, it is only when the working condition changes that the current interference value of the air conditioner is determined that the current interference value can save energy, and the current interference value is determined in time when the working condition changes so as to make corresponding memory frequency processing.

[0079] Step S20, determining a target memory frequency corresponding to the current interference value according to the determined current interference value;

[0080] According to the current interference value, the target memory frequency can be directly determined according to the corresponding relationship between the interference value and the memory frequency, or the target interference level corresponding to the current interference value can be determined first, and then the target memory frequency corresponding to the current interference value can be determined according to the target interference level. The memory frequency refers to the data throughput per second of the internal memory, and the internal memory can be eMMC (Embedded Multi Media Card, embedded memory).

[0081] Please refer to Figure 4 In one embodiment, the step S20 includes:

[0082] Step S21, determining a target interference level where the current interference value is located according to a preset interference level;

[0083] Step S22, determining a target memory frequency corresponding to the target interference level.

[0084] There can be multiple preset interference levels, which can be set according to actual needs, such as setting three interference levels P1, P2, and P3. Different interference levels correspond to different interference value ranges. For example, assuming that the interference value range of P1 is [10, 300), and the interference value range of P2 is [30, 50). Under the preset interference level rules, the target interference level corresponding to the current interference value can be determined. For example, if the current interference value is 40, then the target interference level is P2. Different interference levels also correspond to different memory frequencies. The interference value can be proportional to the interference level, and the interference level is inversely proportional to the memory frequency. That is to say, the larger the current interference value and the higher the interference level, the smaller the target memory frequency between the corresponding wire controller and the air conditioner room. Therefore, when the electromagnetic interference is stronger, the memory frequency of the internal memory in the wire controller is reduced, thereby ensuring the stability of the memory data, so that the wire controller can accurately and reliably control the air conditioner. In addition, by first determining the interference level and then determining the target memory frequency based on the interference level, one purpose is to save air-conditioning system resources, and the other is to prevent the instability of the memory frequency caused by slight changes in the interference value from causing unnecessary trouble to the user and affecting the user's use of the air conditioner.

[0085] In one embodiment, before step S20, the method further includes:

[0086] Step e, determining whether the determined current interference value has changed from the interference value determined last time;

[0087] Step f, if a change occurs, execute the step of determining the target memory frequency corresponding to the current interference value based on the determined current interference value.

[0088] Before determining the target memory frequency, it is possible to first determine whether the current interference value has changed from the interference value determined last time. Only when the current interference value changes will the target memory frequency be further determined and the internal memory in the wire controller accesses data according to the target memory frequency, so as to avoid the air-conditioning system constantly updating the same target memory frequency according to the original interference value, thereby increasing the load of the air-conditioning system. If the current interference value has not changed, it is only necessary to access data according to the original target memory frequency, and there is no need to proceed to the next step. However, if the current interference value changes, it is necessary to proceed to the next steps S20 and S30, so that the new target memory frequency can be re-determined to achieve dynamic adjustment of the memory frequency.

[0089] Step S30: updating the current memory frequency of the air conditioner according to the target memory frequency.

[0090] After the target memory frequency is determined, the memory frequency in the original internal memory is updated to the target memory frequency. Thereafter, unless the current interference value changes, data such as the operating conditions of air-conditioning-related equipment can be stored and accessed according to the current target memory frequency.

[0091] The present invention mainly determines the current interference value of the environment where the air conditioner is located during the operation of the air conditioner, and determines the target memory frequency between the air conditioner and the wire controller according to the current interference value, so that the air conditioner can dynamically adjust the memory frequency of the internal memory in the air conditioner under different electromagnetic interference environments, and ensures the stability of the memory data by dynamically reducing the memory frequency in a relatively strong electromagnetic interference environment, thereby ensuring the accuracy and reliability of the control of the air conditioner by the wire controller or the central control panel, preventing the electromagnetic interference from damaging the data in the internal memory, and avoiding the damage to the air conditioner caused by the influence of electromagnetic interference on the memory data. At the same time, the air conditioner can operate normally and as expected under the control of the wire controller or the central control panel, thereby ensuring the comfort of the indoor environment and improving the user experience.

[0092] Please refer to Figure 5 , Figure 5 The flowchart of the second embodiment of the memory dynamic frequency reduction method of the present invention is shown in FIG. Further, based on the first embodiment of the memory dynamic frequency reduction method of the present invention, the second embodiment of the memory dynamic frequency reduction method of the present invention is proposed. In this embodiment, the memory dynamic frequency reduction method further includes:

[0093] Step S100, determining the current operating function of the air conditioner;

[0094] Step S200, if the currently running function is a personal safety function, then according to the determined current interference value, a target memory frequency corresponding to the current interference value is determined.

[0095] In this embodiment, the current operating function of the air conditioner includes, but is not limited to, one or more combinations of functions such as cooling, heating, fresh air, strong wind, swing wind, dehumidification, noise reduction, defrosting, and sleep. Among them, the functions of heating, fresh air, defrosting, and cooling under extreme outdoor high temperatures can be used as personal safety functions, and other functions can also be used as personal safety functions, which are not limited here. The so-called personal safety function here refers to the fact that the lack of the corresponding function of the air conditioner will affect human health and body functions. It is easier to understand that, for example, in the cold winter, air conditioning heating is an indispensable heating method for users. If the air conditioner cannot heat normally, it will have a certain impact on the user's human health. For example, the indoor air environment is seriously polluted. If the air conditioner cannot provide fresh air normally, it will also have a certain impact on the user's human health. It should be noted that the current operating function here cannot be equivalent to the operating mode of the air conditioner, because the same operating mode can include multiple non-conflicting functions, such as the cooling function and the fresh air function can be performed in the cooling mode or the fresh air mode.

[0096] If it is identified that the current operating function of the air conditioner involves a personal safety function, it is necessary to execute the step of determining the target memory frequency corresponding to the current interference value based on the determined current interference value. The purpose is that in cases involving personal safety, accurate and reliable control of the air conditioner is particularly important. According to the target memory frequency, the memory data in the wire controller can be stably accessed without being damaged, thereby improving the stability and safety of the wire controller's control over the air conditioner and avoiding serious impacts on the user's normal use and personal safety due to unstable memory data.

[0097] In one embodiment, the memory dynamic frequency reduction method further includes:

[0098] Step g, if the currently running function is a personal safety function, detecting whether a parameter setting operation is received;

[0099] Step h: if a parameter setting operation is received, a prompt message is generated indicating that a preset safety mode needs to be entered;

[0100] Step i, upon receiving confirmation to enter the preset safety mode, determining the target memory frequency corresponding to the current interference value according to the determined current interference value.

[0101] In this embodiment, if the current operating function is a personal safety function, it is also possible to detect whether a parameter setting operation is received, that is, to detect whether the user operates the wire controller. If a parameter setting operation is received, it is necessary to remind the user to enter the preset safety mode. The preset safety mode can be a mode that reduces the current memory frequency to the preset safety memory frequency. The preset safety memory frequency can be set according to actual needs. In short, the safety mode is to ensure the reliability of the air conditioner control to ensure the user's personal safety and usage experience. When the user confirms to enter the preset safety mode, the step of determining the target memory frequency corresponding to the current interference value is performed according to the determined current interference value, which will not be repeated here.

[0102] In one embodiment, after step S100, the method further includes:

[0103] If the current operating function is a non-personnel safety function, determining a current memory frequency corresponding to a current compressor frequency of the air conditioner, and determining a target memory frequency corresponding to the current interference value according to the determined current interference value;

[0104] A lower memory frequency between the current memory frequency and the target memory frequency is selected as the current memory frequency.

[0105] If the current operating function is a non-personnel safety function, then the current memory frequency corresponding to the current compressor frequency can be determined. As for how to obtain the current memory frequency corresponding to the current compressor frequency, it can be determined by looking up a table or presetting a compressor frequency-memory frequency curve model. The current memory frequency belongs to the air-conditioning system. The default memory frequency that needs to be adjusted in place when electromagnetic interference does not exist or is not considered. At the same time, according to the determined current interference value, the target memory frequency corresponding to the current interference value is determined. The target memory frequency is the memory frequency determined in order to resist electromagnetic interference while fully considering the electromagnetic interference. The current memory frequency and the target memory frequency are compared and the lower memory frequency is determined as the current memory frequency. This can make the adjustment of the memory frequency more in line with the needs of the current working conditions and the current environment, and to a greater extent ensure the stability of the memory data and the stability, accuracy and reliability of the wire controller's control of the air conditioner.

[0106] In one embodiment, after step S20, the method further includes:

[0107] The target memory frequency is used as the target memory frequency of other indoor units of the air conditioner connected to the same outdoor unit.

[0108] You can continue to refer to Figure 7, you can see that each air conditioner indoor unit has a corresponding wire controller, so only one wire controller is needed to determine the target memory frequency, and send the determined target memory frequency to the air conditioner outdoor unit, and then send it to other wire controllers connected to the same air conditioner outdoor unit through the air conditioner outdoor unit, and use it as the memory frequency of other air conditioners. This greatly saves the computing resources of the air conditioner and improves the efficiency of dynamic updating of the target memory frequency.

[0109] In one embodiment, the memory dynamic frequency reduction method further includes:
