Outdoor unit active detection method for air conditioner indoor and outdoor unit communication mis-wiring

Abstract

The invention relates to air conditioner installation and debugging, in particular to an outdoor unit active detection method for air conditioner indoor and outdoor unit communication mis-wiring. Theproblem that an existing mis-wiring detection method cannot effectively protect communication devices of indoor and outdoor units while detecting serious faults in time is solved. In order to achievethe purpose, the outdoor unit active detection method comprises the following steps that S1, after an air conditioning unit is powered on and before normal communication, a sending port of an outdoorunit sends a set of mis-wiring detection data; S2, a receiving port of the outdoor unit receives feedback data; S3, whether the feedback data is consistent with the detection data or not is judged; S4, if the feedback data is consistent with the detection data, it is judged that mis-wiring does not exist, the outdoor unit and an indoor unit start to normally communicate, otherwise it is judged that mis-wiring exists, and the step S5 is executed; and S5, after waiting for the first set time, the steps S1 to S4 are continued to be executed. Operation is carried out from the outdoor unit side, the initiative is higher, the fault locking speed is higher, and abnormal temperature rise of a communication device can be prevented.

Description

technical field [0001] The invention relates to the installation and debugging of an air conditioner, in particular to an outdoor unit active detection method for communication miswiring of the inner and outer units of the air conditioner. Background technique [0002] According to the feedback from the after-sales personnel of the air conditioner, there are often cases in the market where the power resistor of the communication line of the internal and external units of the air conditioner is burned, resulting in poor communication between the internal and external units, and the air conditioner cannot work normally. After market research and laboratory simulation tests, it was found that it was caused by miswiring of the communication lines of the internal and external units. At present, there is no corresponding prevention and detection method for this problem in the program of the internal and external units. , because the internal unit cannot report a communication fail...

Problems solved by technology

[0006] In order to solve the above problems in the prior art, that is, in order to solve the problem that the existing miswiring detection method cannot detect serious miswiring faults in time and at the same time effectively protect the communication devices of the internal and external units of the air conditioner, the present invention proposes a The outdoor unit active detection method for communication miswiring of the indoor and outdoor units of the air conditioner is characterized in that the method includes the following steps: S1: After the air conditioner unit is powered on and before normal communication, the sending port of the outdoor unit sends a set of misconfiguration S2: The receiving port of the outdoor unit receives the feedback data; S3: Judging whether the feedback data is consistent with the detection data; S4: If the feedback data is consistent with the detection data, it is determined that there is no mismatch The outdoor unit and the indoor unit start normal communication, otherwise it is determined that there is a miswiring and go to step S5; S5: Wait for the first set time and continue to go to steps S1 to S4
