Detailed Description

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating an air conditioner control method according to an exemplary embodiment. It should be noted that, the air-conditioning control method of the present embodiment is executed by an air-conditioning control device, the air-conditioning control device may be implemented by software and/or hardware, and the air-conditioning control device may be configured in an electronic device, and the electronic device may be, for example, an indoor unit; or a controller which is connected with the indoor side unit in a communication way and controls the indoor side unit; or, a controller in the indoor-side unit. The air conditioner control method as shown in fig. 1 includes the steps of:

step 101, under the condition that a communication fault event exists between an indoor side unit and an outdoor side unit of an air conditioner, determining control parameter information to be sent to the outdoor side unit and relay on-off coding information corresponding to the control parameter information.

In the embodiment of the present disclosure, the process of the air conditioner controlling device determining whether there is a communication failure event between the indoor side unit and the outdoor side unit of the air conditioner may be, for example, monitoring a communication state between the indoor side unit and the outdoor side unit; determining whether a communication failure event exists based on a communication state between the indoor side unit and the outdoor side unit for a period of time.

For example, if the communication status is a communication failure status and is maintained for a certain time period, it is determined that a communication failure event is monitored. If the communication state at a part of time points is a communication failure state and the communication state at a part of time points is a communication normal state within a certain time length, determining that a communication fault event is not monitored; or, if the communication states at all time points within a certain time length are the normal communication states, determining that the communication fault event is not monitored.

In the embodiment of the present disclosure, the process of monitoring the communication state may be, for example, that at a certain time point, the control room internal unit sends a reference signal to the outdoor unit through the communication control circuit, and if a response signal for the reference signal is received, it is determined that the communication state at the time point is a normal communication state; and if the response signal aiming at the reference signal is not received within a certain time period, determining that the communication state at the time point is a communication failure state.

In the embodiment of the present disclosure, after the communication failure event is monitored, the cause of the communication failure event may be determined by detecting the states of each circuit in the indoor side unit, each circuit in the outdoor side unit, the state of the communication control circuit between the indoor side unit and the outdoor side unit, and the like. Among them, for example, the communication control circuit has no voltage, and some components in the communication control circuit are damaged.

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 an air conditioning mode. In another example, the control parameter information may be an operating frequency. In another example, the control parameter information may include an air conditioning mode and an operation frequency.

The air conditioning mode comprises a cooling mode and a heating mode. The operating frequency is, for example, an operating frequency required for a motor in the outdoor unit.

In the embodiment of the present disclosure, the process of determining, by the air conditioner control device, the control parameter information to be sent to the outdoor unit and the relay on-off coding information corresponding to the control parameter information may be, for example, determining the control parameter information to be sent to the outdoor unit when a communication fault event exists between the indoor unit and the outdoor unit, and querying a preset coding table according to the control parameter information to obtain the relay on-off coding information corresponding to the control parameter information.

Wherein, different air-conditioning modes can adopt different relay on-off codes; different operating frequencies may employ different relay on-off codes. Taking the single control parameter represented by the on-off code of the 4-bit relay as an example, the on-off code information of the relay corresponding to the control parameter information can be an 8-bit binary number, the first four bits represent the air conditioner mode, and the second four bits represent the operating frequency. When the control parameter information only includes the air-conditioning mode, the last four bits may be preset values, such as 0000; when only the operating frequency is included in the control parameter information, the first four bits may be a preset value, such as 0000.

In the embodiment of the present disclosure, in the relay on-off coding information, 0 may be used to indicate that the power supply relay is in the off state, and 1 may be used to indicate that the power supply relay is in the on state. The interval between two adjacent values may be a preset interval, for example, 50 milliseconds. For example, when the relay on/off code information is 01010010, it indicates that the power supply relay is off for 50 milliseconds, on for 50 milliseconds, off for 100 milliseconds, on for 50 milliseconds, off for 50 milliseconds, and stops the process after the on.

And 102, performing on-off control processing on a power supply relay connecting the indoor side unit and the outdoor side unit according to the relay on-off coding information so as to send control parameter information to the outdoor side unit.

In the embodiment of the disclosure, after the power supply relay connecting the indoor side unit and the outdoor side unit is subjected to on-off control processing according to the relay on-off coding information, the outdoor side unit can monitor the state change condition of the power supply relay, so that the relay on-off coding information is obtained, decoding processing is performed to obtain the control parameter information, and communication between the indoor side unit and the outdoor side unit is realized.

In an embodiment of the present disclosure, the method may further include the steps of: and when the preset shutdown condition is met, the power supply relay is controlled to be switched off until the preset startup condition is met. Namely, when the preset starting condition is met, the power supply relay is controlled to be connected. Wherein the shutdown condition is, for example, at least one of the following conditions: temperature greater than a preset temperature, triggering a protection mechanism, power down, etc.

In the embodiment of the disclosure, because the filter capacitor is arranged in the outdoor unit, based on the characteristic that the filter capacitor stores electric quantity, the outdoor unit can work based on the electric quantity stored by the filter capacitor within a certain time period after the power supply relay is turned off. Therefore, within a certain time period after the power supply relay is switched off, the outdoor unit can monitor that the power supply relay is in a switched-off state, and further monitor the state change condition of the power supply relay. In order to ensure that the outdoor unit can monitor the off state of the power supply relay and ensure the normal operation of the outdoor unit, the off time of the power supply relay needs to be less than a preset time threshold. The time threshold may be determined according to a capacitance of the filter capacitor, a surrounding environment parameter of the filter capacitor, and the like.

According to the air conditioner control method, under the condition that a communication fault event exists between an indoor side unit and an outdoor side unit of an air conditioner, control parameter information to be sent to the outdoor side unit and relay on-off coding information corresponding to the control parameter information are determined; performing on-off control processing on a power supply relay connected with the indoor side unit and the outdoor side unit according to the relay on-off coding information so as to send control parameter information to the outdoor side unit; therefore, when a communication fault event exists between the indoor side unit and the outdoor side unit of the air conditioner, the air conditioner can continue to work, and the working efficiency of the air conditioner is improved.

Fig. 2 is a flowchart illustrating another air conditioner control method according to an exemplary embodiment. In order to accurately monitor a communication fault event and improve the monitoring accuracy of the communication fault event, the communication state between the indoor side unit and the outdoor side unit can be monitored, and whether the communication fault event is monitored or not is determined. As shown in fig. 2, the air conditioner control method may specifically include the following steps:

in step 201, the communication state between the indoor side unit and the outdoor side unit is determined.

In the embodiment of the present disclosure, the communication state may include a communication normal state and a communication failure state. In a normal communication state, the indoor unit and the outdoor unit can normally communicate with each other, that is, the instruction or data of the indoor unit can be sent to the outdoor unit; the instructions or data of the outdoor side unit may also be transmitted to the indoor side unit. In a communication failure state, normal communication between the indoor side unit and the outdoor side unit is difficult, namely, the command or data of the indoor side unit is difficult to send to the outdoor side unit; it is difficult for instructions or data of the outdoor side unit to be transmitted to the indoor side unit.

In the embodiment of the present disclosure, the process of determining the communication state between the indoor side unit and the outdoor side unit may be, for example, that the indoor side unit periodically sends a reference signal to the outdoor side unit, and if a response signal of the outdoor side unit to the reference signal is received within a certain time period, the communication state is determined to be a normal communication state; and if the response signal of the outdoor side unit to the reference signal is not received within a certain time period, determining that the communication state is a communication failure state.

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 time threshold, determining that a communication fault event exists between the indoor side unit and the outdoor side unit of the air conditioner.

In the embodiment of the present disclosure, when the communication state is the communication failure state, and the duration of the communication failure state is greater than or equal to a first time threshold, it is determined that a communication failure event is monitored. If the communication state is the normal communication state; or, determining that the communication fault event is not monitored, wherein the communication state is a communication failure state, and the duration of the communication failure state is less than the first time threshold.

If the communication state is a communication failure state and the duration of the communication failure state is less than the first time threshold, it indicates that the communication state is changed to a communication normal state when the duration is less than the first time threshold, and step 201 to step 202 are executed again from the time point of change.

The first time threshold may be preset. In addition, it should be noted that, in order to facilitate the air conditioner related personnel to know the working state of the air conditioner in time, in an example, after the communication fault event is determined to be monitored, fault related information, such as fault text description, fault code and the like, may be displayed on a display panel of an indoor side unit of the air conditioner, so that the air conditioner user may know that the air conditioner is in fault in time and report the fault in time. In another example, after the communication failure event is determined to be monitored, a prompt message may be sent to a person related to the air conditioner, such as a maintenance person, so that the maintenance person can perform maintenance on the door in time. Wherein, the prompt message may include: the identification of the failed air conditioner, the position information, the contact information of the air conditioner user and the like.

Step 203, determining control parameter information to be sent to the outdoor unit and relay on-off coding information corresponding to the control parameter information under the condition that a communication fault event exists between the indoor unit and the outdoor unit of the air conditioner.

And step 204, performing on-off control processing on the power supply relay connected with the indoor side unit and the outdoor side unit according to the relay on-off coding information so as to send the control parameter information to the outdoor side unit.

It should be noted that, the detailed description of step 203 and step 204 may refer to the description in other embodiments in the present disclosure, and will not be described in detail here.

The air conditioner control method of the embodiment of the disclosure determines the communication state between the indoor side unit and the outdoor side 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 time threshold, determining that a communication fault event exists between an indoor side unit and an outdoor side unit of the air conditioner; under the condition that a communication fault event exists between an indoor side unit and an outdoor side unit of the air conditioner, determining control parameter information to be sent to the outdoor side unit and relay on-off coding information corresponding to the control parameter information; performing on-off control processing on a power supply relay connecting the indoor side unit and the outdoor side unit according to the relay on-off coding information so as to send control parameter information to the outdoor side unit; therefore, when a communication fault event exists between the indoor side unit and the outdoor side unit of the air conditioner, the air conditioner can continue to work, and the monitoring accuracy of the communication fault event and the working efficiency of the air conditioner are improved.

Fig. 3 is a flowchart illustrating another air conditioner control method according to an exemplary embodiment. In order to accurately monitor a communication fault event and improve the monitoring accuracy of the communication fault event, the communication state between the indoor side unit and the outdoor side unit can be monitored, and after the communication failure state lasts for a certain time, the power supply relay is controlled to be disconnected and connected for a certain time, so that whether the communication fault event is monitored or not is determined. As shown in fig. 3, the air conditioner control method may specifically include the following steps:

in step 301, the communication state between the indoor side unit and the outdoor side unit is determined.

In the embodiment of the present disclosure, the communication state may include a communication normal state and a communication failure state. In a normal communication state, the indoor unit and the outdoor unit can normally communicate with each other, that is, the instruction or data of the indoor unit can be sent to the outdoor unit; the instructions or data of the outdoor side unit may also be sent to the indoor side unit. In a communication failure state, normal communication between the indoor side unit and the outdoor side unit is difficult, namely, the command or data of the indoor side unit is difficult to send to the outdoor side unit; it is difficult for instructions or data of the outdoor side unit to be transmitted to the indoor side unit.

And 302, controlling the power supply relay to be disconnected for the first time length and to be connected when the communication state is the communication failure state and the duration of the communication failure state is greater than or equal to the first time length threshold value.

In the embodiment of the present disclosure, when the communication state is the communication failure state, timing may be performed to determine the duration length of the communication failure state; comparing the duration length with a first duration threshold, and if the duration length is smaller than the first duration threshold, continuing timing; if the communication state changes to the normal communication state at a certain time point in the timing process, stopping timing and carrying out zero clearing treatment on the duration time length obtained by timing; when the communication state is changed to the communication failure state, the timer is restarted.

In the embodiment of the disclosure, when the communication state is the communication failure state and the duration of the communication failure state is greater than or equal to the first time threshold, the power supply relay may be controlled to be switched off for the first time, so that the outdoor unit is in a power-down state; and then controlling the power supply relay to be communicated so that the outdoor side unit is in a power-on state.

The outdoor unit is provided with the filter capacitor, and the outdoor unit can work based on the electric quantity stored by the filter capacitor within a certain time period after the power supply relay is switched off based on the characteristic that the filter capacitor stores the electric quantity. Therefore, in order to make the outdoor side unit in a power-down state, the first duration needs to be greater than the preset duration threshold. The preset duration threshold is the maximum duration that the outdoor unit can normally work when the power supply relay is switched off after the filter capacitor is full of stored electric quantity.

The communication state is a communication failure state, and may be caused by other reasons, for example, a voltage at a certain position in the indoor side unit is too low, and for eliminating other reasons, the power supply relay can be controlled to be disconnected for a first time, and the power supply relay is controlled to be connected, so that the communication state is monitored, whether a communication fault event is monitored is determined, and the monitoring accuracy of the communication fault event is further improved.

And 303, when the communication state in the second time period after the power supply relay is connected is a communication failure state, determining that a communication fault event exists between the indoor side unit and the outdoor side unit.

In the embodiment of the disclosure, when the communication state is the communication failure state in the second time period after the power supply relay is connected, the communication failure event is determined to be monitored; and if the communication state at a part of time point in a second time period after the power supply relay is connected is the normal communication state, determining that the communication fault event is not monitored. If the communication state is the normal communication state at a certain time point in the second time period after the power supply relay is connected, the steps 301 to 303 are executed again from the time point, or the steps 302 to 303 are executed again. Wherein the second duration may be less than or equal to the first duration threshold; alternatively, the second time period may be greater than or equal to the first time period threshold, and may be set according to actual needs.

And 304, determining control parameter information to be sent to the outdoor unit and relay on-off coding information corresponding to the control parameter information under the condition that a communication fault event exists between the indoor unit and the outdoor unit.

And 305, performing on-off control processing on a power supply relay connecting the indoor side unit and the outdoor side unit according to the relay on-off coding information so as to send control parameter information to the outdoor side unit.

It should be noted that, the detailed description of step 304 and step 305 may refer to the description in other embodiments in the present disclosure, and will not be described in detail here.

The air conditioner control method of the embodiment of the disclosure determines the communication state between the indoor side unit and the outdoor side 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 time threshold, controlling the power supply relay to be disconnected for the first time and controlling the power supply relay to be connected; when the communication state is a communication failure state within a second time after the power supply relay is connected, determining that a communication fault event exists between the indoor side unit and the outdoor side unit; under the condition that a communication fault event exists between the indoor side unit and the outdoor side unit, determining control parameter information to be sent to the outdoor side unit and relay on-off coding information corresponding to the control parameter information; performing on-off control processing on a power supply relay connected with the indoor side unit and the outdoor side unit according to the relay on-off coding information so as to send control parameter information to the outdoor side unit; therefore, when a communication fault event exists between the indoor side unit and the outdoor side unit of the air conditioner, the air conditioner can continue to work, and the monitoring accuracy of the communication fault event and the working efficiency of the air conditioner are improved.

After the power supply relay connected with the indoor side unit and the outdoor side unit is subjected to on-off control processing according to the relay on-off coding information, the outdoor side unit can decode the received relay on-off coding information to acquire control parameter information sent by the indoor side unit; and performing operation processing according to the control parameter information. For example, the control parameter information includes: an air conditioning mode which is a cooling mode, and an operating frequency which is a required operating frequency of a motor of the outdoor side unit. The outdoor side unit may control the motor therein to operate at the operating frequency to perform the cooling process. The pipeline of the outdoor unit is connected with the pipeline of the indoor unit, and after the outdoor unit carries out refrigeration processing, the temperature of an inner disc of the indoor unit can be gradually reduced after a certain period of time. Therefore, in order to reduce the calculation amount, the current inner disk temperature of the indoor side unit can be determined after delaying for a third time period.

And step 404, determining the working state of the outdoor unit according to the difference value between the current inner disc temperature and the reference inner disc temperature and the control parameter information.

In an embodiment of the present disclosure, the control parameter information includes: and (4) an air-conditioning mode. The reference inner disc temperature may be a preset temperature; or the temperature of the inner disc when the indoor side unit starts to operate; alternatively, the temperature of the inner panel when there is a communication failure event between the indoor side unit and the outdoor side unit, and the like may be set as needed.

In the embodiment of the present disclosure, the difference between the current inner disc temperature and the reference inner disc temperature refers to a value obtained by subtracting the reference inner disc temperature from the current inner disc temperature. In one example, the air conditioning mode is a cooling mode in which the current inner panel temperature is gradually decreased, the current inner panel temperature is less than the reference inner panel temperature, and the difference between the current inner panel temperature and the reference inner panel temperature is a negative value. Therefore, when the difference value between the current inner disc temperature and the reference inner disc temperature is less than or equal to the first difference value threshold, it indicates that the outdoor unit is performing the cooling processing, and it is determined that the working state of the outdoor unit is the normal cooling state. In addition, if the difference between the current inner disc temperature and the reference inner disc temperature is greater than the first difference threshold, it indicates that the outdoor unit does not perform the cooling process, or that a fault occurs in the cooling process.

In another example, the air-conditioning mode is a heating mode in which the current inner panel temperature is gradually increased, the current inner panel temperature is greater than the reference inner panel temperature, and a difference therebetween is a positive value. Therefore, when the difference between the current inner disc temperature and the reference inner disc temperature is greater than or equal to the second difference threshold, it indicates that the outdoor unit is performing heating processing, and it is determined that the working state of the outdoor unit is a normal heating state.

In another example, the air-conditioning mode is a heating mode in which the current inner panel temperature is gradually increased, the current inner panel temperature is greater than the reference inner panel temperature, and a difference therebetween is a positive value. Therefore, when the difference between the current inner disc temperature and the reference inner disc temperature is increased to be greater than or equal to the second difference threshold value, and then the current inner disc temperature is decreased to the first preset temperature, the working state of the outdoor side unit is determined to be the normal defrosting state.

In another example, the air-conditioning mode is a heating mode in which the current inner panel temperature is gradually increased, the current inner panel temperature is greater than the reference inner panel temperature, and a difference therebetween is a positive value. Therefore, when the difference between the current inner disc temperature and the reference inner disc temperature is increased to be greater than or equal to the second difference threshold value, then the current inner disc temperature is decreased to the first preset temperature, and then the current inner disc temperature is increased to the second preset temperature, the working state of the outdoor side unit is determined to be the defrosting completion state.

The first difference threshold value is the difference between the maximum value of the current inner disc temperature and the reference inner disc temperature when the air-conditioning mode is the refrigeration mode; the second difference threshold is the difference between the minimum value of the current inner disc temperature and the reference inner disc temperature when the air-conditioning mode is the heating mode; the first preset temperature and the second preset temperature are absolute temperatures, are generally preset before the air conditioner works and are irrelevant to the reference inner disc temperature.

In the embodiment of the disclosure, the indoor side unit obtains a difference value between the current inner disc temperature and the preset reference inner disc temperature according to the current inner disc temperature and the preset reference inner disc temperature, and determines the working state of the outdoor side unit according to a difference value change curve between the current inner disc temperature and the reference inner disc temperature and the current inner disc temperature change curve in combination with the current air conditioning mode.

Step 405, adjusting the operating state of the indoor unit according to the operating state of the outdoor unit.

In the embodiment of the present disclosure, the operation state of the outdoor side unit is, for example, a normal cooling state, a normal heating state, a normal defrosting state, a defrosting end state, and the like. When the working state of the outdoor side unit is a normal defrosting state, controlling the fan in the indoor side unit to stop running; and when the working state of the outdoor side unit is a defrosting ending state, controlling the fan in the indoor side unit to start and operate.

According to the air conditioner control method, under the condition that a communication fault event exists between an indoor side unit and an outdoor side unit of an air conditioner, control parameter information to be sent to the outdoor side unit and relay on-off coding information corresponding to the control parameter information are determined; performing on-off control processing on a power supply relay connected with the indoor side unit and the outdoor side unit according to the relay on-off coding information so as to send control parameter information to the outdoor side unit; after delaying for a third time, determining the current inner disc temperature of the indoor side unit; determining the working state of the outdoor unit according to the difference between the current inner disc temperature and the reference inner disc temperature and the control parameter information; adjusting the working state of the indoor side unit according to the working state of the outdoor side unit; therefore, when a communication fault event exists between the indoor side unit and the outdoor side unit of the air conditioner, the air conditioner can continue to work, the working state of the indoor side unit can be adjusted according to the working state of the outdoor side unit, and the working efficiency of the air conditioner is improved.

In the embodiment of the present disclosure, the process of monitoring the communication state may be, for example, at a periodic time point, if a reference signal sent by the indoor unit is received at a certain time point, determining that the communication state at the time point and in a subsequent period is a normal communication state; if the reference signal sent by the indoor unit is not received at a certain time point, the communication state at the time point and in a period thereafter is determined to be a communication failure state.

In an implementation manner of the embodiment of the present disclosure, when the indoor side unit periodically sends the reference signal to the outdoor side unit, and when the communication state is the communication failure state, and the duration of the communication failure state is greater than or equal to the first time threshold, it is determined that the communication failure event is monitored.

In an implementation manner of the embodiment of the present disclosure, when an indoor side unit periodically sends a reference signal to an outdoor side unit, if a communication state is a communication failure state and a duration of the communication failure state is greater than or equal to a first time threshold, delaying a first time and re-detecting the communication state; and if the communication state is the communication failure state in the second time length, determining to monitor the communication failure event.

And 502, decoding the on-off coded information of the relay to obtain control parameter information of the indoor unit.

The air conditioning mode comprises a cooling mode and a heating mode. The operating frequency is, for example, an operating frequency required for a motor in the outdoor side unit.

In the embodiment of the present disclosure, the process of the air conditioner control device executing step 502 may be, for example, querying 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.

Wherein, different air-conditioning modes can adopt different relay on-off codes; different operating frequencies may employ different relay on-off codes. Taking the single control parameter represented by the on-off code of the 4-bit relay as an example, the on-off code information of the relay corresponding to the control parameter information can be an 8-bit binary number, the first four bits represent the air conditioner mode, and the second four bits represent the operating frequency. Therefore, the first four bits of the relay on-off coding information can be obtained first, and the air conditioner mode with the first four bits of codes is determined; and then, the last four digits of the on-off coding information of the relay are obtained, and the running frequency with the last four digits of the coding information is determined.

If the first four digits are coded as 0000, it indicates that the indoor unit is not set with the air-conditioning mode; if the last four digits code to 0000, it means that the indoor unit has not set the operating frequency.

And step 503, controlling the working state of the outdoor unit according to the control parameter information.

According to the air conditioner control method, under the condition that a communication fault event exists between an indoor side unit and an outdoor side unit of an air conditioner, the on-off state of a power supply relay connecting the indoor side unit and the outdoor side unit is detected, so that the on-off coding information of the relay is obtained; decoding the on-off coded information of the relay to obtain control parameter information of the indoor unit; controlling the working state of the outdoor unit according to the control parameter information; therefore, when a communication fault event exists between the indoor side unit and the outdoor side unit of the air conditioner, the air conditioner can continue to work, and the working efficiency of the air conditioner is improved.
