Example 1
Embodiment 1 of the present application provides an air conditioning system. Fig. 1 is a schematic view of an air conditioning system according to embodiment 1 of the present application, and as shown in fig. 1, an air conditioning system 100 includes an indoor unit 101, an outdoor unit 102, and a relay 103.
In this embodiment, the indoor unit 101 and the outdoor unit 102 may be connected by a refrigerant pipe and may communicate with each other; the repeater 103 may be used to receive control instructions; the indoor unit 101 may have an indoor unit main control board 1011 that controls the operation of the indoor unit 101; the outdoor unit 102 may have an outdoor unit main control panel 1021 that controls the operation of the outdoor unit 102.
In this embodiment, the repeater 103 may have an instruction converting module 1031, the instruction converting module 1031 may convert the commissioning instruction in the control instructions received by the repeater 103 into a combination of specific operation instructions, and the indoor unit main control board 1011 may control the indoor unit 101 to perform the corresponding combination of specific operations according to the combination of specific operation instructions.
In this embodiment, the outdoor unit main control board 1021 may have a trigger module 10211, and the trigger module 10211 triggers the outdoor unit 102 to enter a commissioning mode when detecting that the indoor unit 101 performs a combination of specific operations; the trigger module 10211 may trigger the outdoor unit 102 to enter the test operation mode when detecting that the indoor unit 101 has received the combination of the specific operation commands.
According to the embodiment, the air conditioning system can convert the received test operation instruction into the combined operation instruction to instruct the indoor units to perform combined operation, and the combined operation of the indoor units is detected or the combined operation instruction is received by the indoor units to trigger the outdoor unit to perform test operation, so that the problem that the combined operation instruction cannot be normally transmitted or received due to communication unsmooth when the combined operation instruction is directly input by a user can be prevented, and in addition, the operation of starting the test operation is simpler.
In this embodiment, the specific operation command can control the indoor unit 101 to perform a corresponding specific operation through the indoor unit main control board 1011, and the specific operation can change the operation state of the outdoor unit 102, so that the outdoor unit 102 can detect whether the indoor unit 101 performs a corresponding specific operation by detecting the change in the operation state of each component in the outdoor unit 102, and send the detection result to the trigger module 10211, for example, the outdoor unit 102 can detect whether the indoor unit 101 performs a corresponding specific operation by detecting the operation state of the four-way valve, and the like.
In this embodiment, the outdoor unit 102 can also detect whether the combination of the specific operation instructions is received by the indoor unit 101 and send the detection result to the trigger module 10211 to control whether to trigger the outdoor unit to enter the commissioning mode. In the case where it is detected that the indoor unit 101 has received the combination of the specific operation commands, the test operation can be started quickly without the combination of the specific operations actually performed by the indoor unit 101, thereby increasing the speed of starting the test operation mode and reducing the power consumption. In this embodiment, the method for detecting whether the indoor unit 101 receives the combination of the specific operation commands may refer to the prior art, and this embodiment will not be described again.
In this embodiment, the combination of the specific operation commands may include any one or a combination of two or more of the type of the specific operation commands, the sequence of the specific operation commands, and/or the interval time between the specific operation commands, and the like, and the combination of the specific operation commands may control the indoor unit 101 to perform the combination of the specific operations.
Fig. 2 is a schematic diagram of a combination of specific operation commands in embodiment 1, and as shown in fig. 2, a combination 200 of specific operation commands may include 3 specific operation commands 201, 202, and 203 arranged in chronological order, and interval times 2011 and 2021 between the operation commands, and the type of each specific operation command is shown in fig. 2.
According to the combination 200 of specific operation instructions shown in fig. 2, the indoor unit 101 may perform the following combination of specific operation instructions: executing a specific operation command 201, namely, setting the target temperature in the refrigeration mode to be 32 ℃, and performing operation corresponding to the setting; elapsed time interval 2011, for example, the time interval 2011 can be a period of time greater than 5 seconds and less than 3 minutes; executing a specific operation command 202, namely, setting the target temperature in the heating mode to be 16 ℃, and performing operation corresponding to the setting; the time interval 2021 elapses, for example, the time interval 2021 may be a period of time greater than 5 seconds and less than 3 minutes; a specific operation command 203 is executed, that is, a target temperature in the cooling mode is set to 16 ℃, and an operation corresponding to the setting is performed.
In the present embodiment, the combination of the specific operation instructions shown in fig. 2 is merely an example, and the present embodiment is not limited thereto.
In this embodiment, the combination of the specific operation instructions may be different from the combination of the normal operation instructions received by the air conditioning system in the normal use state, thereby avoiding the air conditioner from entering the test operation mode due to the normal operation of the user in the normal use state. For example, in a normal use state of the air conditioning system, a user generally selects a cooling mode or a heating mode and sets a corresponding target temperature, thereby giving a normal operation command or combination to the air conditioning system, and the user generally does not give a specific operation command combination 200 in which the cooling mode and the heating mode are frequently switched and the set range of the target temperature is greatly changed in a short time as shown in fig. 2.
In the present embodiment, the instruction converting module 1031 of the relay 103 may convert the trial operation instruction into the combination of specific operation instructions in a manner known in the art, for example, the instruction converting module 1031 may recognize the trial operation instruction in the control instructions and perform encoding processing on the trial operation instruction to generate the combination of specific operation instructions; alternatively, the instruction conversion module 1031 may store a look-up table (look-up table) and store the input control instructions and the output instructions in association with each other, so that when the input control instructions include the commissioning instructions, the instruction conversion module 1031 may output a combination of corresponding specific commissioning instructions in the look-up table.
In this embodiment, as shown in fig. 1, the repeater 103 may further have an inquiry module 1032, and the inquiry module 1032 may inquire, in the storage unit of the air conditioning system, or inquire, via a network, a combination of special operation instructions matching the model of the air conditioning system according to the model of the air conditioning system, and thus the instruction converting module 1031 may convert the commissioning instruction into a combination of specific operation instructions corresponding to the model of the air conditioning system based on an inquiry result of the inquiry module 1032.
In this embodiment, the relay 103 may receive the control instruction directly from the control terminal through the wireless network, or the relay 103 may be connected to a gateway of the access network and receive the control instruction transmitted from the control terminal via the network. Of course, the present embodiment is not limited to this, and the repeater 103 may also receive a control instruction transmitted by the control terminal through the infrared light signal, or the repeater 103 may receive a control instruction and the like from the control terminal through the wired network. The relay unit 103 may receive the control command in any one of the above-described manners, or may receive the control command in two or more of the above-described manners.
In this embodiment, the control terminal may include one or more of a remote controller, a wall controller, a centralized controller, a mobile terminal, a remote server, and the like.
Fig. 3 is a schematic diagram of the repeater 103 receiving control instructions from the control terminal in a different manner. As shown in fig. 3, in the mode (a), the repeater 103 may directly receive a control instruction from the control terminal 200a through the wireless network w1, wherein the control terminal 200a may be a smart phone, for example; in the mode (b), the relay 103 may communicate with the gateway 300 accessed to the network W2, thereby receiving a control instruction transmitted from the control terminal 200b via the network W2, wherein the control terminal 200b may be a remote server, for example, and the relay 103 and the gateway 300 may communicate with each other in a wired manner or in a wireless manner; in the mode (c), the relay 103 may receive a control instruction transmitted by the control terminal 200c through the infrared optical signal W3, where the control terminal 200c may be a remote controller, for example; in the mode (d), the repeater 103 may receive a control instruction from the control terminal 200d through the wired network W4, wherein the control terminal 200d may be, for example, a wall controller.
In this embodiment, as shown in fig. 1, the relay 103 may be connected to the indoor unit main control board 1011 of the indoor unit 101, so that a combination of specific operation commands generated by the command conversion module 1031 of the relay 103 may be transmitted to the indoor unit main control board 1011, thereby controlling the indoor unit 101 to perform the combination of specific operations.
However, the present embodiment is not limited to this, and the relay unit 103 may transmit the command to the indoor unit main control board through another path.
Fig. 4 is another schematic view of an air conditioning system according to embodiment 1 of the present application, and fig. 4 is different from fig. 1 in that in fig. 4, a relay 103 may be connected to an outdoor unit main control panel 1021 of an outdoor unit 102. Thus, in the air conditioning system shown in fig. 4, the relay unit 103 can control the indoor units 101 to perform a combination of specific operations by transmitting the combination of specific operation instructions to the outdoor unit main control panel 1021 and transmitting the combination of specific operation instructions to the indoor unit main control panel 1011 by the outdoor unit main control panel 1021.
According to the embodiment, the air conditioning system can convert the received single trial operation instruction into the combined operation instruction to instruct the indoor units to perform the combined operation, and the combined operation of the indoor units is detected or the combination of specific operation instructions received by the indoor units is detected to trigger the outdoor unit to perform the trial operation, so that the user can reliably start the trial operation of the outdoor unit from the indoor, thereby preventing the problem that the combined operation instruction cannot be normally transmitted or received due to poor communication when the combined operation instruction is directly input by the user, and in addition, the operation of starting the trial operation is simpler.

step 502 of controlling the outdoor unit to enter a test operation mode when detecting that the indoor unit performs the combination of the specific operations or the indoor unit receives the combination of the specific operation commands.
For specific description of each step in this embodiment, reference may be made to the description of the corresponding unit of the air conditioning system in embodiment 1, and this is not repeated here.
According to the embodiment, the air conditioning system can convert the received single test operation instruction into the combined operation instruction to instruct the indoor units to perform the combined operation, and the combined operation of the indoor units is detected or the combination of the specific operation instructions received by the indoor units is detected to trigger the outdoor unit to perform the test operation, so that the user can reliably start the test operation of the outdoor unit from the indoor, thereby preventing the problem that the combined operation instruction cannot be normally transmitted or received due to poor communication when the combined operation instruction is directly input by the user, and in addition, the operation of starting the test operation is simpler.
The present application has been described in conjunction with specific embodiments, but it should be understood by those skilled in the art that these descriptions are intended to be illustrative, and not limiting. Various modifications and adaptations of the present application may occur to those skilled in the art based on the teachings herein and are within the scope of the present application.
