In addition, as shown in fig. 2, fig. 2 is a schematic diagram of hardware connection of an air conditioner according to an embodiment of the present invention. Specifically, according to the internal and external machine matching fault locating method of the air conditioner in the embodiment of the present invention, the air conditioner includes an internal machine and an external machine connected to the power line 400 network. The indoor unit comprises an indoor unit main control module 100 and a central coordinator module which is respectively in network connection with the indoor unit main control module 100 and the power line 400; the outdoor unit includes an outdoor unit main control module 500 and station modules respectively network-connected to the outdoor unit main control module 500 and the power line 400.

Step S100: receiving a pairing starting instruction;
it should be noted that the pairing start instruction may be generated under the control of a user, or may be generated automatically by the internal machine main control module 100 at regular time, which is not limited in this embodiment.
Step S200: generating a pairing instruction based on the pairing starting instruction and sending the pairing instruction to a target module;
it should be noted that the target module includes one of the following combinations: a CCO module 200; CCO module 200 and STA module 300; the CCO module 200, the STA module 300, and the outdoor unit main control module 500.
It should be noted that the pairing instruction pairs the external unit and the internal unit in the same refrigerant system by pairing the internal unit main control module 100 and the external unit main control module 500.
Step S300: determining the fault position of the air conditioner according to the feedback state of the target module;
it should be noted that, because the CCO module 200 is connected to the indoor unit main control module 100 and the power line 400, and the STA module 300 is connected to the outdoor unit main control module 500 and the power line 400, the indoor unit main control module 100 can determine whether a fault exists between the indoor unit main control module 100 and the CCO module 200 through the feedback state of the CCO module 200, and can determine whether a fault exists between the CCO module 200 and the STA module 300 through the feedback state of the STA module 300, and can determine whether a fault exists between the STA module 300 and the outdoor unit main control module 500 through the feedback state of the outdoor unit main control module 500.
It can be understood that, according to the technical solution provided by the embodiment of the present invention, after receiving the pairing start instruction, the internal machine main control module 100 can generate the pairing instruction based on the pairing start instruction and send the pairing instruction to the target module, and then determine the fault location of the air conditioner according to the feedback state of the target module. Because the CCO module 200 is connected to the indoor unit main control module 100 and the power line 400, and the STA module 300 is connected to the outdoor unit main control module 500 and the power line 400, the indoor unit main control module 100 can determine whether a fault exists between the indoor unit main control module 100 and the CCO module 200 through the feedback state of the CCO module 200, and can determine whether a fault exists between the CCO module 200 and the STA module 300 through the feedback state of the STA module 300, and can determine whether a fault exists between the STA module 300 and the outdoor unit main control module 500 through the feedback state of the outdoor unit main control module 500. Therefore, through the technical scheme of the embodiment of the invention, the reason of the pairing fault can be quickly positioned, so that the maintenance efficiency of the air conditioner is improved, and the use experience of a user is optimized.
Referring to FIG. 4, in some embodiments, the target module includes a CCO module 200;
the step S200 includes, but is not limited to, the following step S210.
Step S210: generating a pairing request instruction and sending the pairing request instruction to the CCO module 200;
correspondingly, the above step S300 specifically includes, but is not limited to, the following step S310.
Step S310: when the first feedback signal based on the pairing request command is not received from the CCO module 200, it is determined that a fault exists between the indoor unit main control module 100 and the CCO module 200.
Specifically, after receiving the pairing start instruction, the internal machine main control module 100 generates a pairing request instruction, and then sends the pairing request instruction to the CCO module 200, and when the internal machine main control module 100 does not receive the first feedback signal from the CCO module 200, it indicates that a pairing fault between the internal machine and the external machine occurs, and it can be determined that a fault exists between the internal machine main control module 100 and the CCO module 200, so that the reason for the pairing fault between the internal machine and the external machine of the air conditioner is quickly located, and the overhaul efficiency of workers is improved.
It is understood that the pairing request command may be re-sent to the CCO module 200 when the internal unit main control module 100 does not receive the first feedback signal from the CCO module 200. If the repeated sending exceeds the first preset number of times and the internal unit main control module 100 still does not receive the first feedback signal, it is determined that a fault exists between the internal unit main control module 100 and the CCO module 200. It should be noted that the first preset number of times may be N times, and this embodiment does not limit this.
Referring to fig. 5, in some embodiments, the target module further includes a STA module 300;
the step S200 includes, but is not limited to, the following step S220.
Step S220: when receiving a first feedback signal based on the pairing request instruction from the CCO module 200, generating a pairing state query instruction and sending the pairing state query instruction to the STA module 300 through the CCO module 200;
correspondingly, the above step S300 specifically includes, but is not limited to, the following step S320.
Step S320: when the second feedback signal based on the inquiry pairing state command is not received from the CCO module 200, it is determined that a fault exists between the indoor unit main control module 100 and the CCO module 200.
Specifically, after receiving the pairing start instruction, the internal unit main control module 100 generates a pairing request instruction, and then sends the pairing request instruction to the CCO module 200, and when the internal unit main control module 100 receives a first feedback signal from the CCO module 200, it indicates that no fault exists between the internal unit main control module 100 and the CCO module 200 at this time. Then, the internal machine main control module 100 generates a pairing state query instruction and sends the pairing state query instruction to the STA module 300 through the CCO module 200, and when the internal machine main control module 100 does not receive the second feedback signal from the CCO module 200, it indicates that a pairing failure of the internal machine and the external machine occurs, and it may be determined that a failure exists between the internal machine main control module 100 and the CCO module 200 at this time. It should be noted that, since it takes about 1 to 2 minutes for the indoor unit main control module 100 to generate the query pairing state instruction and send the query pairing state instruction to the STA module 300 through the CCO module 200, if a pairing failure of an indoor unit and an outdoor unit occurs at this time, the reason may be that a failure exists between the indoor unit main control module 100 and the CCO module 200, and not only between the CCO module 200 and the STA module 300. Therefore, the reason of the matching fault of the internal machine and the external machine of the air conditioner can be positioned more quickly and accurately by judging the second feedback signal.
It is understood that when the internal unit main control module 100 does not receive the second feedback signal from the CCO module 200 based on the query pairing state instruction, it may continue to wait and start timing. If the preset time is reached and the internal machine main control module 100 still does not receive the second feedback signal, it is determined that a fault exists between the internal machine main control module 100 and the CCO module 200. It should be noted that the preset time may be 5 minutes, 10 minutes, etc., and this embodiment does not limit the preset time.
Referring to fig. 6, in some embodiments, the target module further includes a STA module 300;
the step S200 includes, but is not limited to, the following step S230.
Step S230: when receiving a first feedback signal based on the pairing request instruction from the CCO module 200, generating a pairing state query instruction and sending the pairing state query instruction to the STA module 300 through the CCO module 200;
correspondingly, the above step S300 specifically includes, but is not limited to, the following step S330.
Step S330: when the pairing failure instruction from the CCO module 200 is received, it is determined that there is a failure between the CCO module 200 and the STA module 300.
Specifically, after receiving the pairing start instruction, the internal unit main control module 100 generates a pairing request instruction, and then sends the pairing request instruction to the CCO module 200, and when the internal unit main control module 100 receives a first feedback signal from the CCO module 200, it indicates that no fault exists between the internal unit main control module 100 and the CCO module 200 at this time. Then, when the internal unit main control module 100 receives the pairing failure instruction from the CCO module 200, it may be determined that there is no failure between the internal unit main control module 100 and the CCO module 200, and at the same time, it may be determined that there is a failure in pairing between the internal unit and the external unit, and it may be determined that there is a failure between the CCO module 200 and the STA module 300.
Referring to fig. 7, in some embodiments, the target module further includes an outdoor unit main control module 500;
the step S200 includes, but is not limited to, the following step S240.
Step S240: when receiving a second feedback signal from the CCO module 200 based on the query pairing state instruction, generating a pairing test instruction and transmitting the pairing test instruction to the external unit main control module 500 through the CCO module 200 and the STA module 300;
correspondingly, the above step S300 specifically includes, but is not limited to, the following step S340.
Step S340: when the third feedback signal based on the pairing test instruction is not received from the external unit main control module 500, it is determined that a fault exists between the STA module 300 and the external unit main control module 500.
Specifically, the internal unit main control module 100 generates a pairing state query command and sends the pairing state query command to the STA module 300 through the CCO module 200, and when the internal unit main control module 100 receives a second feedback signal from the CCO module 200, it indicates that no fault exists between the internal unit main control module 100 and the CCO module 200. Then, the indoor unit main control module 100 generates a pairing test instruction and transmits the pairing test instruction to the outdoor unit main control module 500 through the CCO module 200 and the STA module 300. In this way, when the indoor unit main control module 100 does not receive the third feedback signal from the outdoor unit main control module 500, that is, it indicates that a pairing failure of the indoor unit and the outdoor unit occurs, it may be determined that a failure exists between the STA module 300 and the outdoor unit main control module 500.
It can be understood that, when the indoor unit main control module 100 does not receive the third feedback signal from the outdoor unit main control module 500, the pairing test command may be sent to the outdoor unit main control module 500 again. If the repeated transmission exceeds the second preset number of times and the internal unit main control module 100 still does not receive the third feedback signal, it is determined that a fault exists between the STA module 300 and the external unit main control module 500. It should be noted that the second preset number of times may be N times, and this embodiment does not limit this.
Referring to fig. 8, in some embodiments, regarding step S300, the following step S350 is specifically included, but not limited to.
Step S350: when a pairing test success instruction from the external unit main control module 500 is received, it is determined that the internal unit main control module 100 and the external unit main control module 500 are successfully paired.
Specifically, the indoor unit main control module 100 generates a pairing test instruction and sends the pairing test instruction to the outdoor unit main control module 500 through the CCO module 200 and the STA module 300, and when a third feedback signal from the outdoor unit main control module 500 is received, it may be determined that a fault does not exist between the STA module 300 and the outdoor unit main control module 500. Then, when the indoor unit main control module 100 receives the pairing test success instruction from the outdoor unit main control module 500, it may be determined that the indoor unit main control module 100 and the outdoor unit main control module 500 are successfully paired, that is, the indoor unit and the outdoor unit of the same refrigerant system are successfully paired.
Referring to fig. 9, in some embodiments, the indoor unit further includes an indoor display module 600, and the method for locating the fault in the indoor unit and the outdoor unit of the air conditioner further includes, but is not limited to, the following step S400.
Step S400: according to the feedback state of the target module, the pairing state of the air conditioner is determined, and the pairing state is transmitted to the indoor display module 600.
It can be understood that, after receiving the pairing start instruction, the internal machine main control module 100 adjusts the pairing state of the air conditioner to be pairing, and sends the pairing state to the indoor display module 600, so that the user can know the pairing state of the air conditioner conveniently.
Specifically, the indoor unit main control module 100 may determine whether a fault exists between the indoor unit main control module 100 and the CCO module 200 according to the feedback state of the CCO module 200, may determine whether a fault exists between the CCO module 200 and the STA module 300 according to the feedback state of the STA module 300, and may determine whether a fault exists between the STA module 300 and the outdoor unit main control module 500 according to the feedback state of the outdoor unit main control module 500. If there is a failure, the pairing state of the air conditioner is adjusted to be pairing failure, and the pairing state is transmitted to the indoor display module 600. If there is no fault and the indoor unit main control module 100 receives the pairing test success instruction from the outdoor unit main control module 500, the pairing state of the air conditioner is adjusted to be successful, and the pairing state is sent to the indoor display module 600.
It should be noted that the indoor display module 600 may be a display screen on an indoor unit, and may also be a communication module for sending the pairing status to a specific electronic device, which is not limited in this embodiment.
In some embodiments, the internal unit is also in communication with the remote control 700, and the pairing initiation instruction is generated by the remote control 700.
It can be understood that a user can generate a pairing start instruction by using the remote controller 700 to control the internal unit main control module 100 to perform pairing operation, thereby facilitating the use of the user.
It should be noted that the pairing start instruction may be directly generated by the remote controller 700, and may also be generated by the indoor display module 600 by the remote controller 700 sending an infrared remote control signal to the indoor display module 600, which is not limited in this embodiment.
Based on the internal and external machine matching fault positioning method of the air conditioner in each embodiment of the invention, the whole embodiment of the internal and external machine matching fault positioning method of the air conditioner is provided below.
As shown in fig. 10, fig. 10 is an overall flowchart of a method for positioning an internal/external machine pairing fault of an air conditioner according to an embodiment of the present invention.
In some embodiments, the air conditioner includes a remote controller 700 communicating with the indoor unit, the indoor unit and the outdoor unit connected to the power line 400 network. Specifically, the indoor unit includes an indoor unit main control module 100, an indoor display module 600, and a CCO module 200 respectively network-connected to the indoor unit main control module 100 and the power line 400, and the outdoor unit includes an outdoor unit main control module 500 and a STA module 300 respectively network-connected to the outdoor unit main control module 500 and the power line 400.
It should be noted that the CCO module 200 is an indoor PLC module, the STA module 300 is an outdoor PLC module, PA indicates that the pairing state of the air conditioner is in pairing, C1 indicates that the pairing state of the air conditioner is pairing failure and a fault exists between the CCO module 200 and the STA module 300, C2 indicates that the pairing state of the air conditioner is pairing failure and a fault exists between the indoor main control module 100 and the CCO module 200, C3 indicates that the pairing state of the air conditioner is pairing failure and a fault exists between the STA module 300 and the outdoor main control module 500, and CS indicates that the pairing state of the air conditioner is pairing success.
First, the indoor display module 600 receives a pairing start instruction from the remote controller 700, then displays the PA identifier, and sends the pairing start pairing instruction to the indoor unit main control module 100.
Then, when the indoor unit main control module 100 receives the pairing instruction, the indoor unit main control module 100 generates a pairing request instruction and delays 1s to send the pairing request instruction to the CCO module 200, and meanwhile, the indoor display module 600 keeps displaying the PA identifier. If the internal machine main control module 100 does not receive the first feedback signal based on the pairing request instruction from the CCO module 200, the pairing request instruction is repeatedly sent to the CCO module 200. If the first preset number of times is exceeded and the first feedback signal based on the pairing request instruction is not received from the CCO module 200, it is determined that the pairing is failed, and the indoor display module 600 is controlled to display the identifier of C2. In addition, if the internal machine main control module 100 receives a first feedback signal based on the pairing request instruction from the CCO module 200, it is determined that there is no fault between the internal machine main control module 100 and the CCO module 200 at this time, and the indoor display module 600 is controlled to display the PA identification.
Then, the internal device main control module 100 generates a query pairing command, and then sends the query pairing command to the STA module 300 through the CCO module 200 and starts timing. If the internal machine main control module 100 does not receive the second feedback signal based on the query pairing instruction from the CCO module 200 within the preset time, it is determined that pairing is failed, and the indoor display module 600 is controlled to display the C2 identifier. If the internal device main control module 100 receives the pairing failure instruction from the STA module 300, it determines that pairing has failed, and controls the indoor display module 600 to display the C1 identifier. In addition, if the internal device main control module 100 does not receive the pairing failure instruction from the STA module 300, it is determined that there is no fault between the CCO module 200 and the STA module 300, and the indoor display module 600 is controlled to display the PA identifier.
Finally, the internal unit main control module 100 generates a pairing test instruction and transmits the pairing test instruction to the external unit main control module 500 through the CCO module 200 and the STA module 300. If the indoor unit main control module 100 receives a third feedback signal based on the pairing test instruction from the outdoor unit main control module 500, the pairing test instruction is repeatedly sent to the outdoor unit main control module 500. If the number of times exceeds the second preset number of times, the third feedback signal based on the pairing test instruction from the outdoor unit main control module 500 is still not received, the pairing failure is determined, and the indoor display module 600 is controlled to display the C3 identifier. In addition, if the indoor unit main control module 100 receives the pairing test success instruction from the outdoor unit main control module 500, it determines that pairing is successful, and controls the indoor display module 600 to display the CS identifier.
According to the technical scheme of the embodiment of the invention, after receiving the pairing start instruction, the internal machine main control module 100 can generate the pairing instruction based on the pairing start instruction and send the pairing instruction to the target module, and then determine the fault position of the air conditioner according to the feedback state of the target module, so that the reason of the pairing fault can be quickly positioned, the maintenance efficiency of the air conditioner is improved, and the use experience of a user is optimized.
