Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Fig. 1 is the process flow diagram of the fault detection method of air conditioner according to an embodiment of the invention.As shown in Figure 1, the fault detection method of the air conditioner of the embodiment of the present invention, comprises the following steps:
S1, obtains the acoustic information around air conditioner, and obtains the target operating condition of the air conditioner of user's setting.
Particularly, such as, air conditioner is in operational process, and the noise that air conditioner body produces can have certain feature, if compressor is when steady running, can produce the sound of a fixing frequency.And this voice users is difficult to discover in indoor, but this sound can by the copper pipe of cooling cycle system by transmission sound to indoor set, so, this sound can be collected by the voice pickup module (such as, microphone, acoustic pickup) of indoor set.Meanwhile, voice pickup module (such as, microphone, acoustic pickup) also obtains the sound and other background environment sound etc. that surrounding user sends.
In addition, also need the target operating condition of the air conditioner obtaining active user's setting, such as, the target operating condition of the air conditioner of user's setting is refrigeration mode, and temperature is 22 degree, and wind speed is large wind speed, has fishtail wind etc.
S2, analyzes acoustic information, to obtain the frequency of acoustic information.
Particularly, the acoustic information got is carried out to the Audio Signal Processing of the complexity such as spectrum analysis, to obtain the frequency of acoustic information.
S3, judges the source of acoustic information according to the frequency of acoustic information.
In one embodiment of the invention, wherein, the source of acoustic information is one or more in compressor operation sound, blower fan operating sound, refrigerant flowing sound, the sound of user and background environment sound.
Particularly, air conditioner in the running, the frequency that the building block of air conditioner is sounded and be different from the frequency of the sound of surrounding environment, such as, compressor operation frequency higher (frequency of the sound sent can reach more than 10kHz), the sound frequency high (frequency of sounding than compressor is low) of refrigerant friction copper pipe in refrigeration system, sound during indoor fan running takes second place, and the sound that user sends generally is in low-frequency range (such as, 80Hz-1200Hz).
Further, the frequency range residing for the frequency of acoustic information just can judge the source of acoustic information, and namely whom acoustic information sent by.
S4, carries out fault detect according to the source of acoustic information and target operating condition to air conditioner.
In one embodiment of the invention, wherein, the audio frequency range table that the building block of air conditioner is corresponding under target operating condition is prestored in air conditioner, according to the source of acoustic information and target operating condition, fault detect is carried out to air conditioner, specifically comprise: according to source and the target operating condition inquiry audio frequency range table of acoustic information; If the frequency of acoustic information exceeds the audio frequency range of corresponding building block, then judge that corresponding building block breaks down; If the frequency of acoustic information is in the audio frequency range of corresponding building block, then judge that corresponding building block normally runs.
Particularly, air-conditioning manufacturer can count each building block of air conditioner (such as according to air conditioner product inherent characteristic, compressor, blower fan, copper pipe etc.) operate corresponding audible frequency scope under different target operating condition, with the relation table between the audio frequency range setting up target operating condition and each building block sounding of air conditioner.Such as, when target operating condition is refrigeration, temperature 22 degree, when wind speed is large wind speed, the first sound audio frequency range of compressor operation institute sounding, the second sound audio frequency range etc. of blower fan institute sounding.
Further, such as, if the source of acoustic information is compressor operation sound, then inquire about in audio frequency range table according to target operating condition, compressor.If abnormal sound appears in the HFS of accessed acoustic information, such as, the frequency of HFS has exceeded the audible frequency under compressor maximum frequency of operation, so, just can judge that fault has appearred in compressor.
In one embodiment of the invention, according to the source of acoustic information and target operating condition, fault detect is carried out to air conditioner, specifically comprise: when acoustic information source corresponding to the duty of building block change time, obtain the variation tendency of the frequency of acoustic information; If the variation tendency of the frequency of acoustic information and the variation tendency of duty inconsistent, then judge that corresponding building block breaks down; If the variation tendency of the frequency of acoustic information is consistent with the variation tendency of duty, then judge that corresponding building block normally runs.
Particularly, such as, when compressor reaches raising frequency (or frequency reducing) condition in the running, normal, along with compressor operation frequency is accelerated (or reduction), the frequency that compressor is sounded can promote (or reduction), if now, the trend that the frequency of the high-frequency signal detected does not rise (or reduction), then can judge that compressor breaks down.
Again such as, when the frequency range of the acoustic information detected is refrigerant flowing during the sound frequency range of friction copper pipe, so, can determine whether refrigerant flowing is normal according to the frequency of acoustic information, as compressor at full speed (low speed) runs time, whether the speed of refrigerant flowing accelerates (reduction), or can judge whether pipeline blocks by this acoustic information thereupon.Similarly, operation detection can be carried out according to above-mentioned principle to the device that air-conditioning draught fan or other have specific audio frequency feature, and carry out breakdown judge in conjunction with the audio frequency characteristics that these devices are intrinsic.
In one embodiment of the invention, also comprising: when judging that air conditioner breaks down, generating information, to remind user.
Particularly, when judging that air conditioner breaks down, such as, there is fault in compressor, so, can pass through the display module display reminding information (e.g., display " compressor operating is abnormal ") of air conditioner, to remind user.Certainly, also can by the form reminding user of voice broadcast.
In one embodiment of the invention, before step S3, can also comprise: according to predeterminated frequency scope, acoustic information is screened, to remove sound and/or the background environment sound of user.
Particularly, in order to judge the source of acoustic information more accurately, according to the predeterminated frequency scope arranged, acoustic information can be filtered, filtering noise, such as, the sound that filtering user sends, background environment sound etc.
The fault detection method of the air conditioner of the embodiment of the present invention, obtain the acoustic information around air conditioner, acoustic information analysis is obtained to the frequency of acoustic information, the source of acoustic information is judged according to the frequency of acoustic information, and then according to the intrinsic audio frequency characteristics of some building blocks of air conditioner under target operating condition and current detection to the frequency of acoustic information judge whether air conditioner breaks down, with the reminding user when breaking down, thus improve the intelligent of air conditioner fault detection.
In order to realize above-described embodiment, the present invention also proposes a kind of failure detector of air conditioner.
