In this way, the plurality of candidate air conditioner fault detection parameters are obtained to verify whether the fault detection device is false alarm, so as to realize re-verification of the diagnosis result of the air conditioner fault diagnosis algorithm model, and reduce the false alarm probability of the air conditioner fault diagnosis.

[0061] In some embodiments, the fault detection device is used to collect air conditioner fault detection parameters of the air conditioner for several times in a preset time period, for example, 20 seconds, and the collected air conditioner fault detection parameters are determined as candidate air conditioner fault detection parameters.

[0065] Optionally, the warning of the false alarm situation of the fault detection device comprises: sending a preset prompt information to a preset user terminal to prompt the user to handle the false alarm situation of the fault detection device. For example, the prompt information is "the false alarm times of the fault detection device are 3 times, please handle in time".

[0066] In combination with Figure 3 The embodiments of the present disclosure provide a method for air conditioner fault diagnosis, comprising:

[0067] Step S301, obtaining an air conditioner running parameter;

[0068] Step S302, inputting the air conditioner running parameter into a preset air conditioner fault diagnosis algorithm model to obtain a candidate air conditioner fault diagnosis result; the candidate air conditioner fault diagnosis result is used to represent whether the air conditioner has a fault, and in the case that the candidate air conditioner fault diagnosis result represents that the air conditioner has a fault, the candidate air conditioner fault diagnosis result is an air conditioner fault type;

[0069] Step S303, in the case that the air conditioner has a fault, determining a fault detection device according to the air conditioner fault type;

[0070] Step S304, collecting an air conditioner fault detection parameter by using the fault detection device;

[0071] Step S305, judging whether the air conditioner fault detection parameter is in a first preset range; in the case that the air conditioner fault detection parameter is in the first preset range, step S308 is executed; in the case that the air conditioner fault detection parameter is not in the first preset range, step 306 is executed;

[0075] Thus, the air conditioner is diagnosed for faults by using the air conditioner fault diagnosis algorithm model. In a case where the air conditioner diagnosis result is that the air conditioner has a fault, the air conditioner fault detection parameter is obtained according to the air conditioner fault type. In a case where the air conditioner fault detection parameter is in the first preset range, the fault detection device detects that the air conditioner has a fault, verifying that the diagnosis result output by the air conditioner fault diagnosis algorithm model is correct. In a case where the air conditioner fault detection parameter is not in the first preset range, the fault detection device detects that the air conditioner does not have a fault, and the detection result of the fault detection device is different from the diagnosis result output by the air conditioner fault diagnosis algorithm model. Whether the fault detection device is false positive is determined according to the alternative air conditioner fault detection parameter. In a case where the fault detection device is false positive, it is verified that the diagnosis result output by the air conditioner fault diagnosis algorithm model is correct. Thus, in a case where it is verified that the diagnosis result output by the air conditioner fault diagnosis algorithm model is correct by using the air conditioner fault detection parameter, it is determined that the air conditioner has a fault and a fault alarm is given, which facilitates the user to handle the fault of the air conditioner in a timely manner, and reduces the false positive probability of air conditioner fault diagnosis and improves the user experience.

[0077] Optionally, the preset air conditioner fault type includes a compressor temperature being too high or a motor bearing alarm. If the air conditioner has a fault such as a compressor temperature being too high or a motor bearing alarm, significant loss will be caused if not handled in a timely manner. Thus, in a case where the air conditioner fault type belongs to the preset air conditioner fault type, a fault alarm of the air conditioner is given, so that in a case where the fault detection device is wrong and also wrong when the fault detection device is tested, a fault alarm of the air conditioner is given for a fault of the air conditioner of the preset air conditioner fault type, which facilitates the user to handle in a timely manner and reduces the loss caused by the air conditioner fault.

[0078] In combination with Figure 4 The method for diagnosing a fault of an air conditioner provided by the embodiments of the present disclosure includes:

[0079] In step S401, an air conditioner operating parameter is obtained.

[0080] In step S402, the air conditioner operating parameter is input into a preset air conditioner fault diagnosis algorithm model to obtain an alternative air conditioner fault diagnosis result. The alternative air conditioner fault diagnosis result is used to represent whether the air conditioner has a fault. In a case where the alternative air conditioner fault diagnosis result represents that the air conditioner has a fault, the alternative air conditioner fault diagnosis result is an air conditioner fault type.

[0082] Step S404, collecting air conditioner fault detection parameters by using the fault detection device;

[0083] Step S405, determining whether the air conditioner fault detection parameters are in the first preset range; in the case of air conditioner fault detection parameters in the first preset range, executing step S409; in the case of air conditioner fault detection parameters not in the first preset range, executing step 406;

[0087] Step S409, determining that the air conditioner has failed and performing air conditioner fault alarm.

[0088] In this way, the air conditioner fault diagnosis algorithm model is used to diagnose the fault of the air conditioner, in the case of the air conditioner diagnosis result being that the air conditioner has failed, the air conditioner fault detection parameters are obtained according to the air conditioner fault type, in the case of the air conditioner fault detection parameters being in the first preset range, the fault detection device detects that the air conditioner has failed, verifying that the diagnosis result output by the air conditioner fault diagnosis algorithm model is correct, in the case of the air conditioner fault detection parameters not being in the first preset range, the fault detection device detects that the air conditioner has not failed, which is different from the diagnosis result output by the air conditioner fault diagnosis algorithm model, in the case of false positive of the fault detection device, it is verified that the diagnosis result output by the air conditioner fault diagnosis algorithm model is correct, so that, in the case of verifying that the diagnosis result output by the air conditioner fault diagnosis algorithm model is correct by using the air conditioner fault detection parameters, it is determined that the air conditioner has failed and performs fault alarm, which facilitates the user to timely handle the failure of the air conditioner, reduces the false positive probability of air conditioner fault diagnosis, improves the user's experience, in the case of no false positive of the fault detection device and the air conditioner fault type belonging to the preset air conditioner fault type, the air conditioner fault alarm is performed, so that in the case of error of the fault detection device and error of the fault detection device when verifying the fault detection device, the air conditioner fault alarm is performed for the failure of the air conditioner of the preset air conditioner fault type, which facilitates the user to timely handle and reduces the loss caused by air conditioner failure.
