Abstract

The invention provides an air conditioner upper computer fault treatment method, device and system. The method comprises the steps that a control board in an air conditioner outdoor unit outputs the high level to a relay in the air conditioner outdoor unit, and accordingly the relay can supply power to an air conditioner upper computer; each online signal periodically sent by the air conditioner upper computer in the electrification period is received in real time; when it is monitored that online signals are not received within the continuous first preset time duration range in the electrification period of the air conditioner upper computer, the low level is output to the relay, and accordingly the relay does not supply power to the air conditioner upper computer; and when it is monitored that the continuous time duration for outputting the low level to the relay reaches the second preset time duration, the high level is output to the relay again, and the process is circularly conducted. Visually, the control board can automatically monitor whether the air conditioner upper computer crashes or not, timely treatment is conducted when the air conditioner upper computer crashes, andaccordingly the air conditioner upper computer can recover to the normal work. Thus, by means of the scheme, influences caused on normal usage of an air conditioner due to air conditioner upper computer crash can be weakened.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method, device and system for troubleshooting an air conditioner host computer failure. Background technique [0002] Based on the centralized control technology of the air conditioner, a communication port can be reserved on the host of the air conditioner, and the air conditioner can be connected with the upper computer of the air conditioner through the communication port. In this way, through the data exchange between the air conditioner and the air conditioner host computer, operations such as starting, shutting down, mode setting, and temperature control of the air conditioner can be realized. [0003] At present, the processors of most air conditioner host computers are SOC (System on Chip, system on chip) chips. However, under long-term work, the chip is prone to crash, causing abnormalities in the air conditioner unit and affecting the normal use of the air condit...
