In the multi-connected air conditioner system, one outdoor unit is connected to multiple indoor units. When a certain indoor unit needs to be turned on, it is necessary to go to the room where the indoor unit...

Method used

In this embodiment, a fixed ID value is set for each indoor unit installed, and the terminal sets the option value and corresponds to the ID value. When the user sends a control signal to the indoor unit in this room through the terminal, Determine the ID value corresponding to the option value in the control signal, and then control the indoor unit corresponding to the ID value, so that the user can control any indoor unit by selecting the terminal option value, increasing the convenience of indoor unit control. Wherein, if the terminal does not send an option value, that is, does not select an indoor unit, it defaults to controlling the indoor unit that directly receives the signal instruction, and the control at this time is the same as the traditional indoor unit control.

The control method of the air conditioner system provided by the present invention receives a control signal, and when the control signal is the first control signal, the second control module judges the control signal according to the preset signal discrimination method and signal transmission mode, and selects the corresponding indoor unit, and send the first control signal to the corresponding indoor unit, and then the corresponding indoor unit operates according to the control command corresponding to the control signal. When the control signal is not the first control signal, control the current indoor unit according to the control signal corresponding to the control signal command to run. The present invention establishes a communication channel between the indoor units, so th...

Abstract

The invention provides an air conditioner system and a control method thereof. The air conditioner system comprises an outdoor unit, a plurality of indoor units, first control modules and a second control module. The multiple indoor units are connected with the outdoor unit, each indoor unit is provided with the corresponding first control module, the first control modules are used for receiving control signals sent by a terminal and judging whether the control signals are first control signals or not, and when the judgment result shows that the control signals are the first control signals, the first control signals are sent to the second control module. When the judgment result shows that the control signals are not the first control signals, running of the current indoor unit is controlled according to control instructions corresponding to the control signals. The second control module is arranged on the outdoor unit or any indoor unit and used for receiving the first control signals, the corresponding indoor unit is selected according to the first control signals, and the first control signals are sent to the corresponding indoor unit. According to the air conditioner system and the control method thereof, running of the other assigned indoor units is controlled through the outdoor unit or any indoor unit, and the control convenience of the indoor units is improved.

Example Embodiment

Specific embodiment one:

[0070] A multi-line air-conditioning system capable of mutual linkage control, including an outdoor unit and multiple indoor units. Communication channels are established between the indoor units so that the indoor units can transmit signals to each other and receive remote control signals through any of the indoor units Or commands can control all the internal machines in the multi-line system. For example, when the user sends a signal to the indoor unit 1 with a remote control, the signal instruction is that the indoor unit 2 starts the cooling operation. After the indoor unit 1 receives the signal, the instruction is transmitted to the indoor unit 2, and the indoor unit 2 starts the cooling operation according to the signal. Among them, in the signal transmission process, an indoor unit or outdoor unit can be selected as the host. After any indoor unit receives the control signal, it transmits the signal to the host for signal processing, and then the processed signal is passed to the target Indoor unit.

[0071] After the air conditioner remote control starts to send signals, one of the indoor units receives the remote control signal and instruction, judges the remote control signal and instruction according to the preset signal identification method and transmission method, and transmits the control signal to the target indoor unit. The machine receives the signal and operates according to the received signal. The specific control node process is as follows Figure 4 Shown:

[0072] Step 402, a certain indoor unit receives a remote control signal and instruction;

[0073] Step 404: Transmit remote control signals and instructions to the corresponding indoor unit according to the communication connection mode;

[0074] Step 406, the corresponding indoor unit runs according to the received control instruction.

Example Embodiment

Specific embodiment two:

[0075] A multi-line air-conditioning system includes an outdoor unit and multiple indoor units. After the installation of the air-conditioning system is completed, a fixed ID value is set for each indoor unit installed, and the ID values are 1, 2, 3...n. , All, there are buttons for selecting indoor units in the remote control of the air conditioner, the option values are also 1, 2, 3...n, all, corresponding to each other.

[0076] When the remote control sends a control command, if the indoor unit is not selected, the operation of the indoor unit that directly receives the signal command is adjusted by default. The control at this time is the same as the traditional remote control; when the user is in a room facing the room The indoor unit sends a signal, and the remote control sends a signal with the indoor unit ID that is selected for operation. Since the communication and transmission between the indoor units are established, the indoor unit in the room receives the signal and transmits the signal to the indoor unit with the target ID. The unit operates in accordance with the signal instruction; when the signal instruction selects the indoor unit ID value of "all", the signal is transmitted to all indoor units, and the operation of all indoor units is controlled at the same time. The specific control process is as Figure 5 Shown:

[0077] Step 502, the indoor unit receives a control instruction;

[0078] Step 504: Determine whether the corresponding internal machine ID is included in the control instruction;

[0079] Step 506: When the judgment result is yes, transmit the instruction signal to the indoor unit corresponding to the internal unit ID;

[0080] Step 508, when the judgment result is no, run according to the control command mode.

[0081] In the multi-line system provided by the present invention, the linkage control of the indoor unit provides convenience for control in many occasions, such as bedrooms for elderly people with mobility impairments, baby bedrooms, and temperature adjustment of equipment rooms.

Example Embodiment

Specific embodiment three:

[0082] The terminal is a remote control. The room where the user is located is equipped with indoor unit 1, the outdoor unit serves as the host, and the outdoor unit is equipped with a second control module. The second control module is installed in the outdoor unit to avoid the failure of the air conditioner system due to the power failure of the indoor unit. The problem of normal operation, because the outdoor unit is running continuously, the remote control signal can be transmitted through any indoor unit to achieve the purpose of controlling the operation of other indoor units, ensuring the continuity of the air conditioner system operation, and controlling the multi-connected air conditioning system It provides convenience and provides convenience for air conditioning in the rooms of the elderly and babies.

[0083] Specific steps are as follows:

[0084] Step 1: The user uses the remote control to send a control signal to the indoor unit 1, and the control signal is the indoor unit 2 to start the cooling operation;

[0085] Step 2: After the first control module in the indoor unit 1 receives the control signal, it sends the control signal to the second control module in the outdoor unit;

[0086] Step 3: The second control module in the outdoor unit transmits the control signal to the indoor unit 2;

[0087] Step 4: The indoor unit 2 starts the cooling operation according to the control signal.
