Referring to Fig. 5, Fig. 5 is a third embodiment of a control method of an air conditioning system. Based on the first embodiment, before the step S10, the method further includes:

Step S30: When it is detected that the signal conversion device is respectively connected to the outdoor unit and the indoor unit in communication, the signal conversion device replaces the outdoor unit as the host identity, so as to realize the communication between the outdoor unit and the indoor unit. control.

In this embodiment, when the signal conversion device communicates with the outdoor unit and several indoor units via a serial bus, the signal conversion device communicates with the outdoor unit as an extension, and the outdoor unit When the unit recognizes that there is a communication connection between the signal conversion device and the outdoor unit and the indoor unit via a serial bus, it switches the host identity of the outdoor unit to the extension identity, and then converts to the signal The device sends state transition information, and when the signal conversion device receives the state transition signal, the signal conversion device converts the identity of the extension into the identity of the host, so that the signal conversion device directly controls the outdoor unit and/ Or the indoor unit is controlled.

It should be noted that after the outdoor unit detects that a signal conversion device is connected to the serial communication network between the outdoor unit and several indoor units, the signal conversion device communicates with the outdoor unit and the indoor unit respectively, and the outdoor unit recognizes the signal When the device is converted, the host identity of the outdoor unit is converted to the slave identity. After the signal conversion device detects that the outdoor unit is converted from the host identity to the slave identity, the signal conversion device replaces the outdoor unit to become the master identity, and matches the original outdoor unit. The control logic of several indoor units controls several indoor units. For example, when the signal conversion device receives control information from external equipment, if the control command is to increase the air outlet temperature of the indoor unit 1, the signal conversion device will The control command is sent to the indoor unit 1, and the heat exchanger of the indoor unit 1 increases the current outlet air temperature.

In an embodiment, the control method of the air conditioning system further includes: when it is detected that the target button on the control interface is triggered, determining each target indoor unit and the control corresponding to each target indoor unit according to the control interface Information; each of the control information is sent to the target indoor unit corresponding to each of the control information. In this embodiment,

The signal conversion device is a data converter. Since each indoor unit is in the same local area network, the control terminal or the outdoor unit of the air conditioning system can send control information to the corresponding target indoor unit; when the number of indoor units of the air conditioning system is large, the coverage of the local area network configured for each indoor unit The larger the area, the more routers need to be deployed, which makes the control cost of the air conditioning system higher. In this embodiment, a data converter is used.

It should be noted that the data converter is provided with a WIFI module, and the data converter is located in a room with a network, and is connected to the network through the WIFI module, and then receives control information sent by the control terminal. It should be noted that before sending control information to the data converter, it is necessary to establish a communication connection between the control terminal and the data converter, or to establish a communication connection between the air conditioning system and the data converter. The data converter and the control terminal need to be established. Pairing is performed in advance to establish a communication connection between the two.

In this application, the execution subject can be a control terminal or an air conditioning system. The air conditioning system includes an outdoor unit and at least two indoor units. The air conditioning system can be a multi-air conditioner, and the control terminal can be a remote control or a mobile terminal. The control terminal is loaded with the control APP of the air conditioning system. The running interface of the APP is the control interface of the air conditioning system. The control interface is displayed on the control terminal display screen, so that the user can set the control information of each indoor unit based on the control interface. In addition, the indoor unit of the air conditioning system can also be loaded with APP, so that the display screen of the indoor unit displays the control interface. For ease of description, each embodiment of the present application will be described in detail below with the control terminal as the execution subject.

When the user needs to control each indoor unit, he can set the control information of each indoor unit through the function displayed on the control interface and the parameter corresponding to the function. After the user selects the function and the operating parameter corresponding to the function, click or When the target button is touched, it is determined that the target button is triggered. At this time, the control terminal needs to determine each target indoor unit that the user needs to control and the control information corresponding to each target indoor unit.

Specifically, the control interface includes a multi-control control interface and a full-control control interface. Multi-control refers to the setting of control information for at least two indoor units of the air conditioning system. The multi-control control interface requires the user to check and check The indoor unit that needs to be controlled, and the target indoor unit refers to the indoor unit that the user needs to control. Therefore, the indoor unit checked by the user on the multi-control control interface can be regarded as the target indoor unit, and the check operation is the indoor unit determination operating.

Full control refers to the user's setting of control information for all indoor units of the air conditioning system. If the target button on the full control control interface is triggered, each indoor unit of the air conditioning system will be the target indoor unit.

After determining each target indoor unit, it is necessary to determine the control information corresponding to each target indoor unit. The target button includes a close button and a start button. The control interface is divided into a full control control interface and a multi-control control interface. The control terminal needs to be based on the target button To determine the control information of each target indoor unit, the determination of the control information of the target indoor unit is divided into the following two types:

1. The triggered target button is the start button;

When the start button of the control interface (control interface includes full control interface and multi-control control interface) is triggered, at this time, the function selected by the user is acquired. The function is displayed on the control interface in the form of an icon. There are two states, one is in the on state, the function icon in the on state is lit, and the other is in the off state, the function icon in the off state is dimmed, that is, the function icon is not lit; After the function icon is lit, it can be recognized that the function icon is switched from the off state to the on state, and the function corresponding to the function icon is the selected function. After the function icon is lit, the operating parameters of the function can be adjusted. It is understandable that, When the lighting operation of the function icon is the preset operation, that is, when the preset operation for the function icon on the control interface is detected, the function corresponding to the function icon is taken as the selected function, for example, the user is behind the cooling icon , The sliding button corresponding to the temperature can allow sliding, and the user can determine the cooling temperature corresponding to the cooling according to the sliding button; after determining the selected function and the operating parameters corresponding to the function, if the user clicks on the start button of the control interface or touches the light operation At this time, the control information of each target indoor unit can be generated according to the function and operating parameters. The control information of each target indoor unit is the same, and the control information can be the code corresponding to the control instruction.

2. The triggered target button is the close button;

When the button is turned off when the target button is triggered on the control interface, the shutdown instruction of each target indoor unit is generated, that is, the control information includes the shutdown instruction.

In addition, the control interface is equipped with various functions of the air conditioner, such as cooling, heating, dehumidification, air supply, fresh air, air purification and other functions. These functions are divided into basic functions and auxiliary functions. The basic functions can be cooling and exhausting. For functions such as humidity, heating, and air supply, the air-conditioning system must run basic functions when it is running; the auxiliary functions can be air purification, fresh air and other functions, and the air-conditioning system can run auxiliary functions according to user needs. If the triggered target button is the off button, and the function icon is switched from the on state to the off state, and the function corresponding to the function icon is the basic function (the off operation of the function icon is a preset operation, that is, when the control During the preset operation of the function icon on the interface, the function corresponding to the function icon is used as the selected function), then the shutdown instruction of each target indoor unit is generated; if the triggered target button is the shutdown button, and the selected function is auxiliary When functioning, a function shutdown instruction of each target indoor unit is generated instead of a shutdown instruction.

It can be understood that the control information includes a function shutdown instruction, a shutdown instruction, and a function start instruction.

After the control terminal obtains each control information, it sends each control information to the corresponding target indoor unit, so that each target indoor unit operates according to the control information. After the target indoor unit runs according to the control information, it will feed back response information to the control terminal. If the control terminal receives the response information fed back by the target indoor unit, it will determine the target indoor unit to perform the operation corresponding to the control information. The prompt message that the target indoor unit has run the selected function is displayed on the control interface. In order to ensure that each target indoor unit can operate according to the control information, the control terminal is equipped with a control information retransmission mechanism. When the control terminal does not receive the response information from the target indoor unit within a preset period of time, the response information is not fed back The target indoor unit resends the control information.

It should be noted that the control interface can be displayed on the indoor unit. If the user controls the air conditioning system based on the control interface, the indoor unit is the executive body. At this time, the indoor unit sends various control information to the outdoor unit, and then The outdoor unit sends each control information to the target indoor unit corresponding to each control information.

In the technical solution provided by this embodiment, when the target button on the control interface of the air conditioning system is triggered, the control information corresponding to each indoor unit to be controlled is determined through the control interface, and each control information is sent to the corresponding indoor unit, There is no need for the user to set the control information corresponding to each indoor unit multiple times, which reduces the user's operation process of the air conditioning system, and solves the problem of "the air conditioning system operation process is complicated" in the exemplary technology.

In an embodiment, the control method of the air-conditioning system further includes: obtaining the operating status of each internal machine of the air-conditioning system; determining the dirty state of each internal machine according to the operating status of each internal machine; The target internal machine is determined according to the dirty state, and the target internal machine is controlled to clean.

In this application, the operating status includes the cumulative operating time of the fan of the internal machine, or the operating status includes the current startup time, the current time, the used time of the filter before the current startup, the current fan speed, and the maximum limit of the fan Rotation speed and the design life of the filter.

Since data communication can be carried out between each internal machine and the external machine, and the main control chip of the external machine controls the operation of the internal machine, the external machine can directly determine the current running state of each internal machine.

It should be noted that the air-conditioning system is also provided with a data converter connected to the main control chip of the external machine, and the data converter is provided with a communication module, which can perform wired or wireless communication with the server or the control terminal. The data converter can upload the operating status obtained by the external machine to the server or directly send it to the control terminal, so that the server or the control terminal can obtain the operating status of each internal machine. Among them, each internal machine is provided with an internal machine identification, and the internal machine identification of each internal machine is associated with the operating state of the corresponding internal machine, so that the external machine, service or control terminal can distinguish the operating state of different internal machines.

In this application, when the operating status of each internal machine is obtained, the dirty blocking state of its own filter is determined according to the operating status of each internal machine. When the operating state only includes the cumulative operating time of the fan, the dirty blocking state can be determined only based on the cumulative operating time of the fan. For example, set a preset time. When the cumulative operating time of the fan is equal to or greater than the preset time, it is determined that the filter is dirty; when the cumulative operating time of the fan is less than the preset time, it is determined that the filter is dirty. The blocking state is not dirty. Wherein, the preset duration may be set in the range of (50, 240)h, for example, set to 70h. It is understandable that the value range of the aforementioned preset duration is only used to explain this application, and is not used to limit this application. The value of the preset duration can also be outside the above range.

Or, when the operating parameters include the current startup time, the current time, the used time of the filter before the current startup, the current fan speed, the maximum fan speed limit and the design life of the filter, the remaining use of the filter can be calculated according to the following formula Percentage of life N:

Among them, T ₀ is the used time of the filter before startup, t is the current time, t _{0 is} the startup time, s is the current fan speed, s ₀ is the maximum fan speed limit, b is the adjustment coefficient, and Tn is The design life of the filter.

Then, after calculating the percentage N of the remaining service life of the filter at the current moment, a percentage threshold of the remaining service life of the filter can be set, when the percentage of the remaining service life of the filter is greater than the percentage threshold of the remaining service life of the filter When the filter is dirty and blocked, it is determined that the filter is not dirty; when the percentage of the remaining service life of the filter is less than or equal to the percentage threshold of the remaining service life of the filter, the dirty and blocked status of the filter is determined to be dirty.

In this application, when determining the dirty clogging state of each internal machine, the target internal machine can be determined according to the dirty clogging state, wherein determining the target internal machine according to the dirty clogging state can directly determine the dirty clogging state to meet the preset condition As the target internal machine, the internal machine can also output the dirty state and determine the target internal machine according to the user's choice.

It should be noted that the preset condition may be that the dirty state is dirty, that is, the internal machine whose dirty state is dirty is used as the target internal machine.

After determining the target internal machine, send a cleaning function enable command to the target internal machine to control the target internal machine to perform a corresponding cleaning action.

Specifically, after determining the target internal machine, the external machine controls to close the valve port of the air supply duct corresponding to the target internal machine, and then sends a cleaning function enable signal to the target internal machine. When the target internal machine receives the cleaning function enable signal, it enables its own cleaning function and starts to perform the cleaning action. Wherein, the target internal machine includes a motor, a filter screen, and a filter screen brush. The power output ends of the motor are respectively connected with the filter screen and the filter screen brush, and the filter screen and the filter screen brush are separated from the body of the internal machine. The movable connection, therefore, the filter screen and the filter screen brush can be driven by the motor to move relative to each other. In order to achieve the purpose of brushing the filter. When receiving the cleaning function enable signal, the target internal machine controls the motor operation. To control the internal machine to scrub. In addition, the target internal machine can also be provided with a water tank, and an electromagnetic drain valve is provided on the water tank. When the electromagnetic drain valve is opened, the water in the water tank can be sprayed to the filter screen to achieve the effect of washing the filter screen. When the motor stops running, the target internal machine uses a micro switch to detect whether the filter of the air conditioner is reset. When the filter is detected to be reset, the electromagnetic drain valve of the water tank is opened to flush the filter.

It should be noted that the filter reset refers to the position of the filter when it returns to normal operation. The opening duration of the electromagnetic drain valve may be a preset duration, that is, after the electromagnetic drain valve is opened for the preset duration, the electromagnetic drain valve is closed and the filter screen is stopped from washing. In addition, for other internal machines other than the target internal machine, the external machine sends any instructions to it so that other external machines can continue to run according to the current operating parameters, that is, other internal machines except the target internal machine are not required to be cleaned. Inside machine.
