Abstract
The invention provides an intelligent self-checking method for an air conditioner. Firstly, under the condition that the air conditioner is electrified, a self-checking key is pressed down to enable the air conditioner to enter a self-checking mode, a buzzer sounds to confirm that the self-checking is started at the moment, each load begins to act, and according to software functional setting, the air conditioner outputs all of load information, including a display screen, a fan, a pressing machine, a fan, temperature signals and the like, in a sequence at intervals; and when the air conditioner quits the self-checking mode, all of input/output feedback information is collected, and if a fault appears, the air conditioner represents the fault in the form of the combination of a fault code and a buzzing alarm, and displays through an LED lamp and the fault code, so that a worker can rapidly find out the fault root according to the self-checking fault indication code and remove the fault to enable the air conditioner to return to the normal running state.
Description
Technical field
The present invention relates to the technical field of air-conditioner, refer in particular to a kind of Intelligent self-checking method of air-conditioner.
Background technology
At present, the development of electron trade is more and more intelligent, can handled easily in man-machine communication, comfortable man-machine experience is provided.Air-conditioning is as a part for household electric appliances, and market share amount is larger, and along with the technology of innovation and client's taste lifting day by day, makes the intellectuality of air-conditioning especially aobvious outstanding.And when vast customer demand air-conditioning after-sales service, personnel cannot identify air-condition faults reason and duty fast after sale, need to make long-term complete detection to air-conditioner, cause the wastings of resources such as manpower and materials, customer satisfaction rate is low.For manufacturer, dispatch from the factory and will guarantee the qualification rate of its product in addition, just need to check air conditioner function comprehensively, common online production inspection process and quality sampling observation method inefficiency, take a part for the whole, cannot guarantee rapidly and healthily product quality.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Intelligent self-checking method of rationally reliably air-conditioner is provided, for check and after-sales service before the dispatching from the factory of air-conditioner controller.
For achieving the above object, technical scheme provided by the present invention is: a kind of Intelligent self-checking method of air-conditioner, first in the situation that air-conditioner is switched on, press self check key, make air-conditioner confirm to enter Auto-Sensing Mode, now, buzzer sends sound and confirms to start self check, and each load open initiating is done, all LED lamps of display screen and the complete bright demonstration of charactron, the bad phenomenon that whether has scarce picture, sudden strain of a muscle screen, brightness to differ in order to detection display screen, and show type characteristic code; Then detected temperatures sensor, detects temperature sensor when normal, shows current temperature value, and cannot detected temperatures sensor temperature time, displays temperature sensor fault code; When room temperature and indoor coil temperature approach being detected and be greater than 3 ℃, buzzer warning also shows failure code, represents temperature sensor precision existing problems; Simultaneously, indoor fan brings into operation, exchange PG motor and export high wind, tap motor is exported low wind-apoplexy-Gao wind successively, whether relay opens or cuts out according to different wind speed, in order to sensing chamber's inner blower, work, and whether wind speed setting is normal, if when interchange PG motor is consecutively detected lower than rated speed or without feedback signal, judge fan trouble reveal codes; Whether secondly, all compressors by Control, outer blower fan, cross valve, electrical heating successively adhesive are exported, normal in order to detect load output; Then detect operation conditions and the communication signal of inside and outside air flap, if there is reveal codes of fault; Last air-conditioner exits Auto-Sensing Mode, stops all loads, if there is fault can show successively all corresponding failure codes, and buzzer sends alarm, now, just complete a self check of air-conditioner.
When air-conditioner exits after Auto-Sensing Mode, according to the root of self check indicating fault code table looking up the fault, fix a breakdown afterwards, make air-conditioner recover normal operating condition.
The present invention is after having adopted such scheme, and its great advantage is that method is novel, simple and reliable, can realize all air-conditioner Intelligent self-checkings man-machine communication, can show intuitively failure code and fault zone, greatly enhances productivity; Use after this self checking method, when air-conditioner production is reached the standard grade, can, automatically to its function and operation conditions self check, guarantee that the outgoing of air-conditioner is qualified; For personnel after sale provide intelligentized technical basis, to improve after-sale service quality, promote brand satisfaction simultaneously.
Accompanying drawing explanation
Fig. 1 is control flow chart of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Shown in accompanying drawing 1, the Intelligent self-checking method of air-conditioner described in the present embodiment, first will, in the situation that air-conditioner is switched on, press self check key, make air-conditioner confirm to enter Auto-Sensing Mode, now, buzzer sends sound and confirms to start self check, and each load open initiating is done, the all LED lamps of display screen and the complete bright demonstration of charactron, in order to detection display screen, whether there is scarce picture, dodge screen, the not first-class bad phenomenon of brightness, and show type characteristic code (Dan Leng, two temperature etc., 25G, 35G etc.); Then detected temperatures sensor, detects temperature sensor when normal, shows current temperature value, and cannot detected temperatures sensor temperature time, displays temperature sensor fault code; When room temperature and indoor coil temperature approach being detected and be greater than 3 ℃, buzzer warning also shows failure code, represents temperature sensor precision existing problems; Simultaneously, indoor fan brings into operation, exchange PG motor and export high wind, tap motor is exported low wind-apoplexy-Gao wind successively, whether relay opens or cuts out according to different wind speed, in order to sensing chamber's inner blower, work, and whether wind speed setting is normal, if when interchange PG motor is consecutively detected lower than rated speed or without feedback signal, judge fan trouble reveal codes; Whether secondly, all compressors by Control, outer blower fan, cross valve, electrical heating etc. successively adhesive are exported, normal in order to detect load output; Then detect operation conditions, communication signal of inside and outside air flap etc., if there is reveal codes of fault; Last air-conditioner exits Auto-Sensing Mode, stops all loads, if there is fault can show successively all corresponding failure codes, and buzzer sends " dichloro-diphenyl-dichlorothane ... " acoustic alarm prompting.Now, can check order function information according to the type characteristic code table 1 and 2 shown in below, wherein, shown in type characteristic code table 1 and 2 is specific as follows:
When air-conditioner exits after Auto-Sensing Mode, according to the root of the self check indicating fault code table looking up the fault shown in below, carry out power-off maintenance and after-sales service, to guarantee that air-conditioner recovers normal operating condition, wherein, shown in self check indicating fault code table is specific as follows:
The examples of implementation of the above are only the present invention's preferred embodiment, not with this, limit practical range of the present invention, therefore the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
