And the computer equipment determines that the first misjudgment analysis result is characterized that the alarm information is not the misalarm information based on the abnormal airflow condition. And if the airflow comparison result shows that the simulated airflow organization is consistent with the reference airflow organization, determining that the airflow condition is normal. And the computer equipment determines that the alarm information is represented as false alarm information by the first false judgment analysis result based on the normal airflow condition.

And the computer equipment compares each piece of simulated airflow information with the corresponding reference airflow information respectively to obtain each airflow comparison result.
And step S304, comparing each sensing data with the corresponding reference data respectively through the simulation model to obtain each sensing comparison result.
Specifically, the computer device compares each sensing data with the corresponding reference data through the simulation model based on each sensing data to obtain each sensing comparison result.

and S306, determining the fault reason of the machine room air conditioner according to the fault mapping relation in the simulation model based on each airflow comparison result and each sensing comparison result.
The fault mapping relation is used for representing the mapping relation between the abnormal airflow comparison result and the fault of the air conditioner of the machine room and representing the mapping relation between the abnormal sensing comparison result and the fault reason of the air conditioner of the machine room. In the fault mapping relation, the condition that the outdoor unit fan is damaged and does not rotate, the outdoor unit has no power supply, and the high-voltage switch is not reset corresponds to a compressor high-voltage alarm; the damage of the compressor, the damage of the compressor protector and the poor contact of the control circuit are corresponding to the fault alarm of the precision air conditioner compressor; the A/C system is lack of fluorine and leaks fluorine, the thermal expansion valve is out of order, and the filter screen is too dirty and the fan belt is too loose, which are corresponding to the low-pressure alarm of the precision air conditioner; the A/C power supply reverse phase, the fan breaker switch is not closed, the A/C power supply is in phase failure, the fan belt is too loose, the filter screen is too dirty, and the airflow breaker fails to work, which are corresponding to the precise air conditioner airflow fault alarm; the alarm of the humidifier is not reset, the water inlet valve is not opened, the water inlet valve is damaged, and the damage of the humidifying water tank is corresponding to the fault alarm of the precision air conditioner humidifier.

And the computer equipment determines a mapping fault reason corresponding to the comprehensive comparison result according to the fault mapping relation in the simulation model, and the mapping fault reason is used as the fault reason of the air conditioner of the machine room.
For example, if the comprehensive comparison result is that the rotating speed of the fan is lower than the normal speed of the rotating speed of the fan, the computer device determines that the fault reason of the machine room air conditioner is that the belt of the fan of the machine room air conditioner is too loose based on the fault mapping relation. Wherein too loose of the belt would generate a machine room airflow fault alarm.

And if the display result of the sensing equipment represents that the sensing data is abnormal, determining that the second misjudgment analysis result represents that the alarm information is not the misalarm information.
Specifically, if the first misjudgment analysis result represents that the alarm information is misalarm information, the computer device obtains a sensing display result, and judges the sensing display result through the simulation model. And if the sensing display result represents that the sensing data is abnormal, determining that the second misjudgment analysis result represents that the alarm information is not the misalarm information.
For example, if the first misjudgment analysis result represents that the alarm information is misalarm information, the computer device obtains the sensing display result, and judges the sensing display result through the simulation model.

And analyzing the simulated airflow organization and the plurality of sensing data respectively through the simulation model to obtain each airflow comparison result corresponding to the simulated airflow organization and each sensing comparison result corresponding to the sensing data. And determining the fault reason of the machine room air conditioner based on the various airflow comparison results and the various sensing comparison results.
In this embodiment, if the first misjudgment analysis result represents that the alarm information is misalarm information, the second misjudgment analysis is performed on the alarm information based on the display result of the sensing device to obtain a second misjudgment analysis result. And if the display result of the sensing equipment represents that the sensing data is abnormal, determining that the second misjudgment analysis result represents that the alarm information is not the misalarm information. In this way, the alarm information is judged again based on the display result of the sensing equipment, and the accuracy of the misjudgment analysis can be ensured.

In this embodiment, if the display result of the sensing device indicates that the sensing data is normal, it is determined that the second misjudgment analysis result indicates that the alarm information is misalarm information, and the second misjudgment analysis result is sent to the monitoring system. Therefore, the error warning information can be filtered in time, so that fault detection based on the error warning information is avoided, and the efficiency of the detection result is greatly improved.
