Whether system breaks down, so having reached the technique effect much sooner of the fault detect to refrigeration system, and due to being not required to
The experience of testing staff to be depended on, so have more accurate technique effect.
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment is
The a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.
On the one hand, the embodiment of the present invention provides a kind of information processing method, is applied to air-conditioning, refer to Fig. 1, concrete bag
Include:
Step s101: detect the sound letter of the throttling arrangement obtaining air-conditioning by being arranged at the sound detection device of air-conditioning
Breath；
Step s102: judge whether the sound value corresponding to acoustic information is less than predetermined threshold value；
Step s103: when sound value is less than predetermined threshold value it is determined that the refrigeration system of air-conditioning breaks down.
In step s101, throttling arrangement acts primarily as the effect of throttling and blood pressure lowering.Can for can multiple throttling arrangements, below
Enumerate three kinds therein to be introduced, certainly, in specific implementation process, be not limited to following three kinds of situations.
The first, particularly as follows: capillary tube, capillary tube can be the capillary tube being arranged at air-conditioner outdoor unit to throttling arrangement,
Can be the capillary tube of the indoor set being arranged at air-conditioning, this embodiment of the present invention is not restricted.Under normal circumstances, capillary tube patch
On the vaporizer of air-conditioning, in refrigeration systems, will be by larger when the liquid that condenser flows out is through tiny capillary tube
Resistance, therefore liquid refrigerant flow reduce, limit cold-producing medium enter vaporizer flow, make to keep relatively in condenser
Stable pressure, the pressure differential at capillary tube two ends also keeps stable, so that the refrigerant pressure of entrance vaporizer is reduced, carries out
Sufficiently evaporation endothermic, reaches the purpose of refrigeration, capillary tube typically adopt internal diameter 0.6～2.0mm about copper tube, its length
Depending on the flow determining after performance of refrigerant systems coupling.
Second, throttling arrangement, particularly as follows: expansion valve, rises before expansion valve mainly cold-producing medium entrance condenser condensation heat release
Hypotensive effect, but from unlike capillary-compensated, expansion valve is and the linkage of unit electronic-controlled installation, according to temperature-sensing probe institute
The temperature signal of transmission is carrying out refrigerant flow control.
The third, throttling arrangement particularly as follows: capillary tube and expansion valve, in this case, due to hair can be considered
Tubule and the acoustic information of expansion valve, so have more accurate technique effect.
In step s102, identical predetermined threshold value can be set for all of air-conditioning, for example: 10db, 20db etc.,
For the feature of different air-conditionings itself, different predetermined threshold value can be set, for example: for the less air-conditioning of noise, default threshold
Value is less, for example: 5db, 10db, that so can detect is more accurate；For the air-conditioning that noise is larger, predetermined threshold value is larger,
For example: 20db, 30db, so it is prevented from air conditioner noises are detected as the acoustic information of throttling arrangement, and then lead to produce mistake
Judged result by mistake.
If it is generally the case that sound value is less than predetermined threshold value, such as in step s103: predetermined threshold value is 20db, sound
It is worth for 0db, then explanation refrigeration system breaks down, for example: lack cold-producing medium, throttling arrangement blocking etc., so there is not system
The flowing of cryogen, and then the sound of cold-producing medium flowing is also can't detect by sound detection device.
Or it is directed to same air-conditioning, repeatedly carry out repeating to test, judge in the case that refrigeration system breaks down,
Sound value will usually be less than how many, for example, in the case that 5 refrigeration systems of detection break down, determines following sound respectively
Value: 10db, 12db, 15db, 20db, 25db, then may finally average as predetermined threshold value, for example: 20db, or
Take wherein minimum value as predetermined threshold value, for example: 10db etc., this embodiment of the present invention is not restricted.
As further preferred embodiment, judge the sound value corresponding to acoustic information whether less than predetermined threshold value it
Afterwards, method also includes:
When sound value is more than predetermined threshold value, determine that refrigeration system does not break down.
Because sound value is more than threshold value, then there is the flowing of cold-producing medium in explanation throttling arrangement, so determining refrigeration system
Do not break down.For example: if predetermined threshold value is 20db, sound value is 25db it is determined that refrigeration system does not break down.
As further preferred embodiment, judge the sound value corresponding to acoustic information whether less than predetermined threshold value it
Afterwards, refer to Fig. 2, method also includes:
Step s201: when sound value is more than predetermined threshold value, by the first voiceprint in acoustic information and default vocal print letter
Breath is mated；
Step s202a: if the first voiceprint mates with default voiceprint it is determined that event in refrigeration system
Barrier；
Step s202b: otherwise it is determined that refrigeration system breaks down.
In specific implementation process, vocal print had both had specificity, namely its voiceprint of different sound differs, vocal print
Also there is stability, namely be directed to same sound, its voiceprint is identical, so refrigeration in the throttling arrangement that can prestore
The voiceprint of the sound of agent flowing as default voiceprint, gathered by voice collection device obtain acoustic information it
Afterwards, from acoustic information, just extract the first voiceprint, then the first voiceprint is mated with default voiceprint.
In step s202a, because the first voiceprint is mated with default voiceprint, then explanation voice collection device is adopted
The sound that the acoustic information integrating flows as throttling arrangement inner refrigerant, so determine that refrigeration system does not break down.
In step s202b, because the first voiceprint with default voiceprint and mismatches, then voice collection device is described
The acoustic information the being gathered sound that not throttling arrangement inner refrigerant flows, and the possibly noise of air-conditioning itself or environment
Noise, so not cold-producing medium flowing in explanation throttling arrangement, so determining that refrigeration system breaks down.
As further preferred embodiment, when sound value is less than predetermined threshold value, method also includes:
Produce an information, to point out refrigeration system to break down.
In specific implementation process, air-conditioning can produce polytype information, be set forth below three kinds therein and enter
Row is introduced, and certainly, in specific implementation process, is not limited to following three kinds of situations.
The first, information produces information particularly as follows: voice messaging, namely by the speaker of air-conditioning, for example
Following information " refrigeration system of air-conditioning breaks down, and please overhauls in time and safeguards " is exported by speaker；
Second, information particularly as follows: text prompt information, for example: in the case that air-conditioning comprises display unit,
The display unit of air-conditioning exports following information " refrigeration system of air-conditioning breaks down, and please overhauls in time and safeguards "；
The third, information, particularly as follows: short message prompt information, if only having old man and child to be in family, all cannot
Air-conditioning is overhauled, so a short message prompt information can be produced, such as: in the after-sale service business of air-conditioning or family
Adult sends following short message prompt information " refrigeration system of air-conditioning breaks down, and please overhauls in time and safeguards " etc..
On the other hand, based on same inventive concept, the embodiment of the present invention provides a kind of air-conditioning, refer to Fig. 3, comprising:
Detection module 30, for detecting the sound of the throttling arrangement obtaining air-conditioning by being arranged at the sound detection device of air-conditioning
Message ceases；
Judge module 31, for judging whether the sound value corresponding to acoustic information is less than predetermined threshold value；
