Field fault detection system and method for air-conditioner

Abstract

The invention relates to a field fault detection system and method for an air-conditioner. The system comprises a first subsystem and a second subsystem; the first subsystem is used for acquiring operation data of an air-conditioner outdoor unit; and the second subsystem is used for acquiring operation data of an air-conditioner indoor unit, receiving the operation data sent by the first subsystem, processing and analyzing the operation data of the air-conditioner indoor and outdoor units to detect whether the air-conditioner is abnormal or not, and determining a maintenance scheme. The systemimproves the automatic data acquisition degree, solves the problems that maintenance personnel carry various testing tools to manually acquire the individual datum, and thus errors are prone to occurand data acquisition is asynchronous, reduces the maintenance difficulty, and improves the equipment detection efficiency and the professionalism; and various operation data of the air-conditioner can be continuously acquired after the system is installed once, so that maintenance personnel are prevented from frequently entering the outdoor air-conditioner installation position, and the system isbeneficial to reducing potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of electrical equipment maintenance, in particular to an on-site fault detection system and method for an air conditioner. Background technique [0002] At present, the warranty period of products in the air-conditioning and refrigeration industry is extended. According to the reliability theory, it is inevitable that air conditioners will fail when they are used for a long time and run in harsh environments. When users complain about poor air-conditioning effects, system high-voltage protection, compressor overload, and high power consumption , low wind speed of the internal unit, condensation at the tuyere of the internal unit, etc., the maintenance personnel will carry multimeters, ammeters, thermometers, hygrometers, mechanical pressure gauges, anemometers, and stroboscopes to the user site to check the operating voltage, current, Parameters such as air outlet temperature, system temperature, system pres...

AI Technical Summary

Problems solved by technology

[0003] Problem 1: There are many types of detection tools and they are scattered, requiring manual collection of individual data, which is prone to errors and the collected data is not synchronized, resulting in increased difficulty in repairing air conditioner faults, misjudgment of faults, multiple repairs, replacement of wrong parts, low maintenance efficiency, and maintenance costs At the same time, user complaints have a great impact on the company's brand image;

[0004] Problem 2: The faulty air conditioner cannot predict the time period of the fault. When the data is being collected, a fault occurs and multiple key data are not recorded. Secondary data collection is required. The maintenance personnel need to go out of the outer wall again to collect the operating data of the external unit. Working at heights brings great safety hazards to maintenance personnel
