[0036] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] Figure 1 is a flow chart of an air conditioning control method according to an exemplary embodiment. It should be noted that the air conditioning control method of this embodiment is executed by an air conditioning control device, which can be implemented by software and / or hardware. The air conditioning control device can be configured in an electronic device, which can be, for example, an indoor unit; or a controller that communicates with the indoor unit and controls the indoor unit; or a controller in the indoor unit. Figure 1 The air conditioning control method shown comprises the following steps:

[0039] Step 101, in the event of a communication failure event between the indoor unit and the outdoor unit of the air conditioner, determine control parameter information to be sent to the outdoor unit and relay on / off coding information corresponding to the control parameter information.

[0040] In the embodiment of the present disclosure, the process of the air conditioning control device determining whether there is a communication failure event between the indoor unit and the outdoor unit of the air conditioner can be, for example, monitoring the communication status between the indoor unit and the outdoor unit; and determining whether there is a communication failure event based on the communication status between the indoor unit and the outdoor unit over a period of time.

[0041] For example, if the communication status is a communication failure status and remains for a certain period of time, it is determined that a communication failure event has been detected. If the communication status is a communication failure status at some time points within a certain period of time, and the communication status is a normal communication status at some time points, it is determined that no communication failure event has been detected; or, if the communication status is a normal communication status at all time points within a certain period of time, it is determined that no communication failure event has been detected.

[0042] In the embodiment of the present disclosure, the process of monitoring the communication status may, for example, be that at a certain point in time, the control room inner unit sends a reference signal to the outdoor unit through the communication control circuit; if a response signal to the reference signal is received, the communication status at that point in time is determined to be a normal communication state; if no response signal to the reference signal is received within a certain period of time, the communication status at that point in time is determined to be a communication failure state.

[0043] In the embodiment of the present disclosure, after a communication failure event is detected, the cause of the communication failure event can be determined by detecting the state of each circuit in the indoor unit, the state of each circuit in the outdoor unit, the state of the communication control circuit between the indoor unit and the outdoor unit, etc. The cause may be, for example, no voltage in the communication control circuit, damage to some components in the communication control circuit, etc.

[0044] In an embodiment of the present disclosure, the control parameter information includes at least one of the following parameters: air conditioning mode, operating frequency. In one example, the control parameter information may be the air conditioning mode. In another example, the control parameter information may be the operating frequency. In another example, the control parameter information may include the air conditioning mode and the operating frequency.

[0045] The air conditioning mode includes a cooling mode and a heating mode. The operating frequency, for example, the operating frequency required for the motor in the outdoor unit.

[0046] In the embodiment of the present disclosure, the process of the air-conditioning control device determining the control parameter information to be sent to the outdoor unit and the relay on-off coding information corresponding to the control parameter information can be, for example, when there is a communication failure event between the indoor unit and the outdoor unit, determining the control parameter information to be sent to the outdoor unit, querying a preset coding table according to the control parameter information, and obtaining the relay on-off coding information corresponding to the control parameter information.

[0047] Different air-conditioning modes can use different relay on-off codes; different operating frequencies can use different relay on-off codes. Taking a single control parameter represented by a 4-bit relay on-off code as an example, the relay on-off code information corresponding to the control parameter information can be an 8-bit binary number, the first four bits represent the air-conditioning mode, and the last four bits represent the operating frequency. When the control parameter information only includes the air-conditioning mode, the last four bits can be a preset value, such as 0000; when the control parameter information only includes the operating frequency, the first four bits can be a preset value, such as 0000.

[0048] In the embodiment of the present disclosure, in the relay on-off coding information, 0 can be used to indicate that the power supply relay is in a disconnected state, and 1 can be used to indicate that the power supply relay is in a connected state. Among them, the interval between two adjacent values ​​can be a preset interval, for example, 50 milliseconds. For example, if the relay on-off coding information is 01010010, it means that the power supply relay is disconnected for 50 milliseconds, connected for 50 milliseconds, disconnected for 50 milliseconds, connected for 50 milliseconds, disconnected for 100 milliseconds, connected for 50 milliseconds, disconnected for 50 milliseconds, and stopped processing after being connected.

[0049] Step 102, performing on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information, so as to send the control parameter information to the outdoor unit.

[0050] In the embodiment of the present disclosure, after the power supply relay connecting the indoor unit and the outdoor unit is controlled on and off according to the relay on-off coding information, the outdoor unit can monitor the state changes of the power supply relay, and then obtain the relay on-off coding information, decode it to obtain the control parameter information, and realize communication between the indoor unit and the outdoor unit.

[0051] In the embodiment of the present disclosure, the method may further include the following steps: when the preset shutdown condition is met, the power supply relay is controlled to be disconnected until the preset startup condition is met. That is, when the preset startup condition is met, the power supply relay is controlled to be connected. The shutdown condition is, for example, at least one of the following conditions: the temperature is greater than the preset temperature, the protection mechanism is triggered, the power is off, etc.

[0052] In the disclosed embodiment, since a filter capacitor is provided in the outdoor unit, based on the characteristics of the filter capacitor storing electricity, within a certain period of time after the power supply relay is disconnected, the outdoor unit can operate based on the electricity stored in the filter capacitor. Therefore, within a certain period of time after the power supply relay is disconnected, the outdoor unit can monitor that the power supply relay is in a disconnected state, and then monitor the state change of the power supply relay. In order to ensure that the outdoor unit can monitor the disconnected state of the power supply relay and ensure the normal operation of the outdoor unit, the disconnection time of the power supply relay needs to be less than a preset time threshold. In particular, the time threshold can be determined based on the capacitance of the filter capacitor, the surrounding environmental parameters of the filter capacitor, etc.

[0053] The air conditioning control method of the disclosed embodiment determines control parameter information to be sent to the outdoor unit and relay on-off coding information corresponding to the control parameter information when a communication failure event occurs between the indoor unit and the outdoor unit of the air conditioner; performs on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information to send the control parameter information to the outdoor unit; thereby, when a communication failure event occurs between the indoor unit and the outdoor unit of the air conditioner, the air conditioner can continue to work, thereby improving the working efficiency of the air conditioner.

[0054] Figure 2 is a flow chart of another air conditioning control method according to an exemplary embodiment. In order to accurately monitor communication failure events and improve the monitoring accuracy of communication failure events, the communication status between the indoor unit and the outdoor unit can be monitored to determine whether a communication failure event is detected. Figure 2 As shown, the air conditioning control method may specifically include the following steps:

[0055] Step 201, determining the communication status between the indoor unit and the outdoor unit.

[0056] In the disclosed embodiment, the communication state may include a normal communication state and a communication failure state. In the normal communication state, the indoor unit and the outdoor unit can communicate normally, that is, the instructions or data of the indoor unit can be sent to the outdoor unit; the instructions or data of the outdoor unit can also be sent to the indoor unit. In the communication failure state, it is difficult for the indoor unit and the outdoor unit to communicate normally, that is, it is difficult for the instructions or data of the indoor unit to be sent to the outdoor unit; the instructions or data of the outdoor unit are difficult to be sent to the indoor unit.

[0057] In the embodiment of the present disclosure, the process of determining the communication status between the indoor unit and the outdoor unit may, for example, be that the indoor unit periodically sends a reference signal to the outdoor unit, and if a response signal from the outdoor unit to the reference signal is received within a certain time period, the communication status is determined to be a normal communication status; if no response signal from the outdoor unit to the reference signal is received within a certain time period, the communication status is determined to be a communication failure status.

[0058] Step 202: When the communication state is a communication failure state and the duration of the communication failure state is greater than or equal to a first duration threshold, it is determined that a communication failure event exists between the indoor unit and the outdoor unit of the air conditioner.

[0059] In the embodiment of the present disclosure, when the communication state is a communication failure state, and the duration of the communication failure state is greater than or equal to the first duration threshold, it is determined that a communication failure event is monitored. If the communication state is a normal communication state; or the communication state is a communication failure state, and the duration of the communication failure state is less than the first duration threshold, it is determined that no communication failure event is monitored.

[0060] Among them, if the communication state is a communication failure state, and the duration of the communication failure state is less than the first duration threshold, it means that the communication state is changed to a normal communication state when the duration is less than the first duration threshold, then steps 201 to 202 are re-executed from the change time point.

[0061] Among them, the first duration threshold can be preset. In addition, it should be noted that in order to facilitate the air-conditioning related personnel to understand the working status of the air-conditioning in a timely manner, in one example, after determining that a communication failure event is monitored, the fault-related information can be displayed on the display panel of the indoor unit of the air-conditioning, such as a text description of the fault, a fault code, etc., so that the air-conditioning user can promptly understand that the air-conditioning has a failure and report it in time. In another example, after determining that a communication failure event is monitored, a prompt message can be sent to the air-conditioning related personnel, such as maintenance personnel, so that the maintenance personnel can come to the door for repair in time. Among them, the prompt information may include: the identification of the faulty air-conditioning, location information, contact information of the air-conditioning user, etc.

[0062] Step 203, in the event of a communication failure event between the indoor unit and the outdoor unit of the air conditioner, determine the control parameter information to be sent to the outdoor unit and the relay on / off coding information corresponding to the control parameter information.

[0063] Step 204, performing on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information, so as to send the control parameter information to the outdoor unit.

[0064] It should be noted that for the detailed description of step 203 and step 204, reference may be made to the description in other embodiments of the present disclosure, and will not be described in detail here.

[0065] The air conditioning control method of the disclosed embodiment determines the communication status between the indoor unit and the outdoor unit; when the communication status is a communication failure status and the duration of the communication failure status is greater than or equal to a first duration threshold, determines that a communication failure event exists between the indoor unit and the outdoor unit of the air conditioner; in the case of a communication failure event between the indoor unit and the outdoor unit of the air conditioner, determines control parameter information to be sent to the outdoor unit, and relay on-off coding information corresponding to the control parameter information; performs on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information, so as to send the control parameter information to the outdoor unit; thereby, when a communication failure event occurs between the indoor unit and the outdoor unit of the air conditioner, the air conditioner can continue to work, thereby improving the accuracy of communication failure event monitoring and the working efficiency of the air conditioner.

[0066] Figure 3 is a flow chart of another air conditioning control method according to an exemplary embodiment. In order to accurately monitor communication failure events and improve the monitoring accuracy of communication failure events, the communication status between the indoor unit and the outdoor unit can be monitored. After the communication failure state lasts for a certain period of time, the power supply relay is controlled to disconnect for a certain period of time and then connected, thereby determining whether a communication failure event is detected. Figure 3 As shown, the air conditioning control method may specifically include the following steps:

[0067] Step 301, determining the communication status between the indoor unit and the outdoor unit.

[0068] In the disclosed embodiment, the communication state may include a normal communication state and a communication failure state. In the normal communication state, the indoor unit and the outdoor unit can communicate normally, that is, the instructions or data of the indoor unit can be sent to the outdoor unit; the instructions or data of the outdoor unit can also be sent to the indoor unit. In the communication failure state, it is difficult for the indoor unit and the outdoor unit to communicate normally, that is, it is difficult for the instructions or data of the indoor unit to be sent to the outdoor unit; the instructions or data of the outdoor unit are difficult to be sent to the indoor unit.

[0069] In the embodiment of the present disclosure, the process of determining the communication status between the indoor unit and the outdoor unit may, for example, be that the indoor unit periodically sends a reference signal to the outdoor unit, and if a response signal from the outdoor unit to the reference signal is received within a certain time period, the communication status is determined to be a normal communication status; if no response signal from the outdoor unit to the reference signal is received within a certain time period, the communication status is determined to be a communication failure status.

[0070] Step 302: When the communication state is a communication failure state and the duration of the communication failure state is greater than or equal to a first duration threshold, control the power supply relay to be disconnected for a first duration, and control the power supply relay to be connected.

[0071] In the embodiment of the present disclosure, when the communication status is a communication failure status, timing can be performed to determine the duration of the communication failure status; the duration is compared with a first duration threshold, and if the duration is less than the first duration threshold, the timing continues; if the communication status changes at a certain point in time during the timing process and changes to a normal communication status, the timing is stopped and the duration obtained by the timing is cleared; when the communication status changes to a communication failure status, the timing is restarted.

[0072] In an embodiment of the present disclosure, when the communication state is a communication failure state and the duration of the communication failure state is greater than or equal to a first duration threshold, the power supply relay can be controlled to disconnect for a first duration so that the outdoor unit is in a power-off state; then the power supply relay can be controlled to be connected so that the outdoor unit is in a power-on state.

[0073] Among them, since a filter capacitor is provided in the outdoor unit, based on the characteristics of the filter capacitor storing electricity, the outdoor unit can work based on the electricity stored in the filter capacitor within a certain period of time after the power supply relay is disconnected. Therefore, in order to put the outdoor unit in a power-off state, the first duration needs to be greater than the preset duration threshold. Among them, the preset duration threshold is the maximum duration that the outdoor unit can work normally when the filter capacitor stores full electricity and the power supply relay is disconnected.

[0074] Among them, since the communication status is a communication failure state, it may be caused by other reasons, such as the voltage at a certain location in the indoor unit is too low. In order to eliminate other reasons, the power supply relay can be controlled to disconnect for the first time period, and the power supply relay can be controlled to be connected, and then the communication status can be monitored to determine whether a communication failure event is detected, thereby further improving the monitoring accuracy of communication failure events.

[0075] Step 303: When the communication state is a communication failure state within a second time period after the power supply relay is connected, it is determined that a communication failure event exists between the indoor unit and the outdoor unit.

[0076] In the embodiment of the present disclosure, when the communication state is a communication failure state within the second time period after the power supply relay is connected, it is determined that a communication failure event is monitored; if the communication state is a normal communication state at some time points within the second time period after the power supply relay is connected, it is determined that no communication failure event is monitored. Wherein, if the communication state is a normal communication state at a certain time point within the second time period after the power supply relay is connected, then starting from this time point, step 301 to step 303 are re-executed, or step 302 to step 303 are re-executed. Wherein, the second time period may be less than or equal to the first time period threshold; or, the second time period may be greater than or equal to the first time period threshold, and can be set according to actual needs.

[0077] Step 304: in the event of a communication failure between the indoor unit and the outdoor unit, determine the control parameter information to be sent to the outdoor unit and the relay on / off coding information corresponding to the control parameter information.

[0078] Step 305 , performing on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information, so as to send the control parameter information to the outdoor unit.

[0079] It should be noted that for the detailed description of step 304 and step 305, reference may be made to the descriptions in other embodiments of the present disclosure, and will not be described in detail here.

[0080] The air conditioning control method of the disclosed embodiment determines the communication status between the indoor unit and the outdoor unit; when the communication status is a communication failure status and the duration of the communication failure status is greater than or equal to a first duration threshold, controls the power supply relay to disconnect for a first duration, and controls the power supply relay to connect; when the communication status is a communication failure status within a second duration after the power supply relay is connected, determines that a communication failure event exists between the indoor unit and the outdoor unit; in the case of a communication failure event between the indoor unit and the outdoor unit, determines control parameter information to be sent to the outdoor unit, and relay on-off coding information corresponding to the control parameter information; performs on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information, so as to send the control parameter information to the outdoor unit; thereby, when a communication failure event occurs between the indoor unit and the outdoor unit of the air conditioner, the air conditioner can continue to work, thereby improving the accuracy of communication failure event monitoring and the working efficiency of the air conditioner.

[0081] Figure 4 FIG. 1 is a flow chart of another air conditioning control method according to an exemplary embodiment. In order to facilitate the adjustment of the working state of the indoor unit, the change state of the inner disk temperature of the indoor unit can be monitored to determine the working state of the outdoor unit. Figure 4 As shown, the air conditioning control method may specifically include the following steps:

[0082] Step 401, in the event of a communication failure event between the indoor unit and the outdoor unit of the air conditioner, determine control parameter information to be sent to the outdoor unit and relay on / off coding information corresponding to the control parameter information.

[0083] Step 402, performing on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information, so as to send the control parameter information to the outdoor unit.

[0084] It should be noted that for the detailed description of step 401 to step 402, reference may be made to the description of other embodiments in the present disclosure, and will not be described in detail here.

[0085] Step 403, after delaying for a third time period, determine the current inner disk temperature of the indoor unit.

[0086] In the embodiment of the present disclosure, the process of the air-conditioning control device executing step 403 may be to perform timing processing at the end time point of the process of performing on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information, or at the start time point of the process of performing on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information; after the timing time is greater than or equal to the third time period, the current inner disk temperature of the indoor unit is detected in real time.

[0087] Among them, after the power supply relay connecting the indoor unit and the outdoor unit is subjected to on-off control processing according to the relay on-off coding information, the outdoor unit can decode the received relay on-off coding information to obtain the control parameter information sent by the indoor unit; and perform operation processing according to the control parameter information. For example, the control parameter information includes: air conditioning mode and operating frequency, the air conditioning mode is cooling mode, and the operating frequency is the required operating frequency of the motor of the outdoor unit. Then the outdoor unit can control the motor therein to operate at the operating frequency to perform cooling processing. The pipeline of the outdoor unit is connected to the pipeline of the indoor unit. After the outdoor unit performs cooling processing, it takes a certain period of time for the inner disk temperature of the indoor unit to gradually decrease. Therefore, in order to reduce the amount of calculation, the current inner disk temperature of the indoor unit can be determined after a third delay.

[0088] Step 404, determining the working state of the outdoor unit according to the difference between the current inner disk temperature and the reference inner disk temperature, and the control parameter information.

[0089] In the disclosed embodiment, the control parameter information includes: air conditioning mode. The reference internal disk temperature may be a preset temperature; or the internal disk temperature when the indoor unit starts running; or the internal disk temperature when there is a communication failure event between the indoor unit and the outdoor unit, etc., which may be set according to actual needs.

[0090] In the embodiment of the present disclosure, the difference between the current inner disk temperature and the reference inner disk temperature refers to the value obtained by subtracting the reference inner disk temperature from the current inner disk temperature. In one example, the air-conditioning mode is the cooling mode, at which time the current inner disk temperature is gradually decreasing, the current inner disk temperature is less than the reference inner disk temperature, and the difference between the two is a negative value. Therefore, when the difference between the current inner disk temperature and the reference inner disk temperature is less than or equal to the first difference threshold, it indicates that the outdoor unit is performing cooling processing, and the working state of the outdoor unit is determined to be a normal cooling state. In addition, if the difference between the current inner disk temperature and the reference inner disk temperature is greater than the first difference threshold, it indicates that the outdoor unit is not performing cooling processing, or that there is a fault in the cooling process, etc.

[0091] In another example, the air conditioning mode is the heating mode, at this time the current inner disk temperature is gradually increasing, the current inner disk temperature is greater than the reference inner disk temperature, and the difference between the two is a positive value. Therefore, when the difference between the current inner disk temperature and the reference inner disk temperature is greater than or equal to the second difference threshold, it indicates that the outdoor unit is performing heating processing, and the working state of the outdoor unit is determined to be a normal heating state.

[0092] In another example, the air conditioning mode is the heating mode, at which time the current inner disk temperature is gradually increasing, the current inner disk temperature is greater than the reference inner disk temperature, and the difference between the two is a positive value. Therefore, when the difference between the current inner disk temperature and the reference inner disk temperature first increases to a value greater than or equal to the second difference threshold, and then the current inner disk temperature drops to the first preset temperature, it is determined that the working state of the outdoor unit is a normal defrosting state.

[0093] In another example, the air conditioning mode is the heating mode, at this time the current inner disk temperature is gradually increasing, the current inner disk temperature is greater than the reference inner disk temperature, and the difference between the two is a positive value. Therefore, when the difference between the current inner disk temperature and the reference inner disk temperature first rises to a value greater than or equal to the second difference threshold, then the current inner disk temperature drops to the first preset temperature, and then the current inner disk temperature rises to the second preset temperature, it is determined that the working state of the outdoor unit is the defrosting end state.

[0094] Among them, the first difference threshold is the difference between the current maximum inner disk temperature and the reference inner disk temperature when the air-conditioning mode is cooling mode; the second difference threshold is the difference between the current minimum inner disk temperature and the reference inner disk temperature when the air-conditioning mode is heating mode; the first preset temperature and the second preset temperature are absolute temperatures, which are generally preset before the air-conditioning works and have nothing to do with the reference inner disk temperature.

[0095] In the embodiment of the present disclosure, the indoor unit obtains the difference between the current inner disk temperature and the preset reference inner disk temperature. The working status of the outdoor unit can be determined based on the difference change curve between the current inner disk temperature and the reference inner disk temperature and the current inner disk temperature change curve combined with the current air-conditioning mode.

[0096] Step 405: Adjust the working state of the indoor unit according to the working state of the outdoor unit.

[0097] In the disclosed embodiment, the working state of the outdoor unit is, for example, a normal cooling state, a normal heating state, a normal defrosting state, a defrosting end state, etc. When the working state of the outdoor unit is a normal defrosting state, the fan in the indoor unit is controlled to stop running; when the working state of the outdoor unit is a defrosting end state, the fan in the indoor unit is controlled to start running.

[0098] The air conditioning control method of the disclosed embodiment determines, in the event of a communication failure event between the indoor unit and the outdoor unit of the air conditioner, control parameter information to be sent to the outdoor unit and relay on-off coding information corresponding to the control parameter information; performs on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information to send the control parameter information to the outdoor unit; determines the current inner disk temperature of the indoor unit after a third delay period; determines the working state of the outdoor unit according to the difference between the current inner disk temperature and the reference inner disk temperature, and the control parameter information; adjusts the working state of the indoor unit according to the working state of the outdoor unit; thereby, when a communication failure event occurs between the indoor unit and the outdoor unit of the air conditioner, the air conditioner can continue to work, and can adjust the working state of the indoor unit according to the working state of the outdoor unit, thereby improving the working efficiency of the air conditioner.

[0099] Figure 5 is a flow chart of another air conditioning control method according to an exemplary embodiment. It should be noted that the air conditioning control method of this embodiment is executed by an air conditioning control device, which can be implemented by software and / or hardware. The air conditioning control device can be configured in an electronic device, which can be, for example, an outdoor unit; or a controller that communicates with the outdoor unit and controls the outdoor unit; or a controller in the outdoor unit. Figure 5 As shown, the specific process is as follows:

[0100] Step 501, in the event of a communication failure event between the indoor unit and the outdoor unit of the air conditioner, detecting the on-off state of a power supply relay connecting the indoor unit and the outdoor unit to obtain relay on-off coding information.

[0101] In the embodiment of the present disclosure, the process of the air conditioning control device determining whether there is a communication failure event between the indoor unit and the outdoor unit of the air conditioner can be, for example, monitoring the communication status between the indoor unit and the outdoor unit; and determining whether there is a communication failure event based on the communication status between the indoor unit and the outdoor unit over a period of time.

[0102] In the embodiment of the present disclosure, the process of monitoring the communication status may, for example, be that at periodic time points, if a reference signal sent by the indoor side unit is received at a certain time point, then the communication status at that time point and within a subsequent period is determined to be a normal communication state; if a reference signal sent by the indoor side unit is not received at a certain time point, then the communication status at that time point and within a subsequent period is determined to be a communication failure state.

[0103] In one implementation of the embodiment of the present disclosure, when the indoor unit periodically sends a reference signal to the outdoor unit, when the communication state is a communication failure state and the duration of the communication failure state is greater than or equal to a first duration threshold, it is determined that a communication failure event is monitored.

[0104] In one implementation of the embodiment of the present disclosure, when the indoor unit periodically sends a reference signal to the outdoor unit, if the communication status is a communication failure status and the duration of the communication failure status is greater than or equal to a first duration threshold, the communication status is delayed for a first duration and re-detected; if the communication status is a communication failure status within a second duration, it is determined that a communication failure event is monitored.

[0105] Step 502: Decode the relay on / off coding information to obtain control parameter information of the indoor unit.

[0106] In an embodiment of the present disclosure, the control parameter information includes at least one of the following parameters: air conditioning mode, operating frequency. In one example, the control parameter information may be the air conditioning mode. In another example, the control parameter information may be the operating frequency. In another example, the control parameter information may include the air conditioning mode and the operating frequency.

[0107] The air conditioning mode includes a cooling mode and a heating mode. The operating frequency, for example, the operating frequency required for the motor in the outdoor unit.

[0108] In the disclosed embodiment, the process of the air conditioning control device executing step 502 may be, for example, to query a preset coding table according to the relay on-off coding information to obtain control parameter information corresponding to the relay on-off coding information.

[0109] Among them, different air-conditioning modes can use different relay on-off codes; different operating frequencies can use different relay on-off codes. Taking a single control parameter represented by a 4-bit relay on-off code as an example, the relay on-off code information corresponding to the control parameter information can be an 8-bit binary number, the first four bits represent the air-conditioning mode, and the last four bits represent the operating frequency. Therefore, the first four bits of the relay on-off code information can be obtained first to determine the air-conditioning mode with the first four bits of code; then the last four bits of the relay on-off code information can be obtained to determine the operating frequency with the last four bits of code.

[0110] Among them, if the first four digits are 0000, it means that the air-conditioning mode is not set for the indoor unit; if the last four digits are 0000, it means that the operating frequency is not set for the indoor unit.

[0111] Step 503: Control the working state of the outdoor unit according to the control parameter information.

[0112] The air conditioning control method of the disclosed embodiment detects the on-off state of the power supply relay connecting the indoor unit and the outdoor unit of the air conditioner in the event of a communication failure between the indoor unit and the outdoor unit to obtain relay on-off coding information; decodes the relay on-off coding information to obtain control parameter information of the indoor unit; controls the working state of the outdoor unit according to the control parameter information; thereby, when a communication failure occurs between the indoor unit and the outdoor unit of the air conditioner, the air conditioner can continue to work, thereby improving the working efficiency of the air conditioner.

[0113] Figure 6 The figure is a schematic diagram of the structure of an air conditioner according to an exemplary embodiment.

[0114] like Figure 6 As shown, the air conditioner includes: an indoor unit 61 and an outdoor unit 62.

[0115] The indoor unit 61 and the outdoor unit 62 are connected in communication; the indoor unit 61 and the outdoor unit 62 are connected via a power supply relay 611 .

[0116] Among them, the indoor unit 61 monitors whether there is a communication failure event between the indoor unit 61 and the outdoor unit 62 of the air conditioner; when a communication failure event occurs between the indoor unit 61 and the outdoor unit 62 of the air conditioner, the indoor unit 61 determines the control parameter information to be sent to the outdoor unit 62, and the relay on-off coding information corresponding to the control parameter information; the indoor unit 61 performs on-off control processing on the power supply relay 611 connecting the indoor unit 61 and the outdoor unit 62 according to the relay on-off coding information, so as to send the control parameter information to the outdoor unit.

[0117] Among them, the outdoor unit 62 monitors whether there is a communication failure event between the indoor unit 61 and the outdoor unit 62 of the air conditioner; when a communication failure event occurs between the indoor unit 61 and the outdoor unit 62 of the air conditioner, the outdoor unit 62 detects the on-off state of the power supply relay connecting the indoor unit 61 and the outdoor unit 62 to obtain the relay on-off coding information; the outdoor unit 62 decodes the relay on-off coding information to obtain the control parameter information of the indoor unit 61; and controls the working state of the outdoor unit according to the control parameter information.

[0118] in, Figure 7 FIG. 1 is a schematic diagram of another air conditioner structure according to an exemplary embodiment. Figure 7 As shown, in Figure 6 Based on the embodiment shown, the indoor side unit 61 may further include an indoor microcontroller unit (MCU) 612 and a first communication control circuit 613. The indoor microcontroller unit 612 is connected to the first communication control circuit 613 and the power supply relay 611 respectively.

[0119] Among them, Figure 7 As shown, the outdoor unit 62 includes an outdoor microcontroller unit (MCU) 621, a power filter and switch power circuit 622, a power voltage detection circuit 623, and a second communication control circuit 624. The outdoor microcontroller unit 621 is connected to the power filter and switch power circuit 622, the power voltage detection circuit 623, and the second communication control circuit 624, respectively.

[0120] Among them, Figure 7 As shown, the power supply relay 611 is connected to the power supply filter and switch power supply circuit 622 and the power supply voltage detection circuit 623 through the live wire; the first communication control circuit 613 and the second communication control circuit 624 are connected through the communication line. The power supply voltage detection circuit 623 and the indoor micro control unit 612 are respectively connected to the neutral line. The first communication control circuit 613 and the second communication control circuit 624 constitute the communication control circuit of the air conditioner.

[0121] In the embodiment of the present disclosure, the indoor micro control unit 612 serves as the controller of the indoor unit and is used to control the operation of the indoor unit 61. The power supply relay 611 is used to send the relay on-off coding information to the power supply voltage detection circuit 623 and the power supply filter and switching power supply circuit 622 of the outdoor unit. The first communication control circuit 613 is used to communicate with the outdoor unit 62.

[0122] Therefore, the working process of the indoor unit is as follows: the first communication control circuit 613 of the indoor unit 61 cannot establish communication with the second communication control circuit 624 of the outdoor unit 62, and sends this information to the indoor micro control unit 612. Then the indoor micro control unit 612 encodes the control parameter information of the indoor unit to obtain the relay on-off coding information, controls the on-off state of the power supply relay 611, and sends the relay on-off coding information to the outdoor unit 62.

[0123] In the embodiment of the present disclosure, the outdoor micro control unit 621 is used to control the operation of the outdoor unit 62, the power supply filtering and switching power supply circuit 622 is used to eliminate interference and ensure that the outdoor unit can operate based on the power stored in the filter capacitor within a certain period of time after the power supply relay 611 is disconnected, the power supply voltage detection circuit 623 is used to detect the on-off time interval and the number of on-off times of the power supply relay 611, and the second communication control circuit 624 is used to communicate with the indoor unit 61.

[0124] The working process of the outdoor unit is as follows: the second communication control circuit 624 of the outdoor unit 62 cannot establish communication with the first communication control circuit 613 of the indoor unit 61, and sends this information to the outdoor micro control unit 621, the power supply voltage detection circuit 623 detects the on-off time interval and the number of on-off times of the power supply relay 611 to obtain the relay on-off coding information, and the outdoor micro control unit 621 parses the control parameter information of the indoor unit 61 according to the relay on-off coding information detected by the power supply voltage detection circuit 623, thereby controlling the working state of the outdoor unit 61.

[0125] Due to the existence of filter capacitors in the power filtering and switching power supply circuits of the outdoor unit, when the power supply relay in the indoor unit is disconnected, the outdoor unit can still work normally. However, the capacitance of the filter capacitor is limited, so information cannot be sent through the power supply relay during the operation of the compressor and fan in the outdoor unit. The compressor and fan are respectively connected to the outdoor micro-control unit, power filtering and switching power supply circuits. The outdoor micro-control unit controls the working status of the compressor and fan, and the power supply relay supplies power to the compressor and fan through the power filtering and switching power supply circuits.

[0126] In summary, the air conditioner provided by the embodiment of the present disclosure includes: an indoor unit and an outdoor unit; wherein the indoor unit and the outdoor unit are communicatively connected; wherein the indoor unit monitors a communication failure event between the indoor unit and the outdoor unit of the air conditioner; in the event of a communication failure event between the indoor unit and the outdoor unit of the air conditioner, determines control parameter information to be sent to the outdoor unit, and relay on-off coding information corresponding to the control parameter information; performs on-off control processing on the power supply relay connecting the indoor unit and the outdoor unit according to the relay on-off coding information, so as to send the control parameter information to the outdoor unit; the outdoor unit controls the working state of the outdoor unit according to the control parameter information; thereby, when a communication failure event occurs between the indoor unit and the outdoor unit of the air conditioner, the air conditioner can continue to work, thereby improving the working efficiency of the air conditioner.
