Air-conditioner fault self-examining method, tool and device

Abstract

The invention discloses an air-conditioner fault self-examining method, tool and device. The method comprises the steps that the self-examining tool and an external unit and an internal unit of an air-conditioner are connected; after the air-conditioner is started, the external unit is actively in communication with the internal unit, and the self-examining tool enters in a monitoring mode to monitor the data transmitted between the external unit and the internal unit; the self-examining tool controls the external unit and the internal unit to enter in a self-examining mode according to the monitored data; the external unit and the internal unit enter the self-examining mode and output self-examining data; and if the self-examining tool monitors fault data, the self-examining tool displays fault information according to the fault data. According to the air-conditioner fault self-examining method, tool and device, the self-examining tool is used for conducting troubleshooting guide on faults, achieves air-conditioner fault self-examining, and can quickly and accurately determine the position and causes of the faults through monitoring data; and during air-conditioner after-sale maintenance, the tool can be connected easily, and the overcoming speed and quality of after-sale faults are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner failure self-check method, self-check tooling and an air conditioner failure self-check device. Background technique [0002] At present, if the air conditioner breaks down, the maintenance personnel will carry out maintenance by asking and testing to determine the location and cause of the failure. However, maintenance personnel cannot directly search for detailed information about the fault, and it takes a long time to determine the location and cause of the fault. It is difficult to accurately judge the fault and perform maintenance quickly and accurately. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide an air conditioner failure self-inspection method, self-inspection tooling and air-conditioner failure self-inspection device to at least solve the problem in the prior art that it is difficult to quickly and accurate...
