Embodiment Construction

[0021] Such as figure 1 As shown, in the embodiment of the present invention, a fault diagnosis method for an air-conditioning unit is provided, which includes: detecting the state information of the air-conditioning unit and judging whether there is abnormal state information in the state information of the air-conditioning unit. For state information, the abnormal state information is transmitted to the data processing center in real time through the first wireless data communication network, and the normal state information other than the abnormal state information is transmitted to the data processing center through the second wireless data communication network.

[0022] Further, when there is no abnormal state information in the status information of the air conditioning unit, the status information of the air conditioning unit is transmitted to the data processing center through the second wireless data communication network. When uploading the status information of the...

Abstract

The invention discloses an air conditioning unit fault diagnosis method. The method comprises the following steps that status information of an air conditioning unit is detected, and whether abnormalstatus information exists in the status information of the air conditioning unit is judged; when the abnormal status information exists in the status information of the air conditioning unit, all theabnormal status information is transferred to a data processing center by a first wireless data communicating network in real time; and normal status information other than the abnormal status information is transmitted to the data processing center through a second wireless data communicating network. According to the air conditioning unit fault diagnosis method, the abnormal status information can be transferred to the data processing center in time. The invention further discloses an air conditioning unit fault diagnosis system.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a fault diagnosis method and system for an air conditioning unit. Background technique [0002] When the air conditioner unit is working, the controller will detect the unit’s operating conditions, operating environment, and current unit status. If the unit enters an abnormal operating state at a certain moment, the controller will feed back fault information to the host computer and stop the air conditioner unit from working. , at this time the display will display the fault information sent by the main board, [0003] At the same time, the wireless data transmission module of the air-conditioning unit (integrated with a data flow card) will upload the fault information to the data center, and the system has the following problems: [0004] When the wireless data transmission module uploads fault information, it is easily restricted by the state of the network connection, and th...
