Include following steps:
Step S102, the power supply that voltage detection unit detection air-conditioning uses；
Step S104, the processor coupled with above-mentioned voltage detection unit judges that whether the magnitude of voltage of above-mentioned power supply is predetermined
In the range of, and, in the case of the magnitude of voltage of above-mentioned power supply is not in above-mentioned preset range, send order, wherein, above-mentioned life
Order is used for carrying out alerting and/or being controlled above-mentioned air-conditioning.
Being detected the power supply of air-conditioning by voltage detection unit, the magnitude of voltage of power supply is to use a kind of processor to determine
No in predetermined scope, when the supply voltage detected not within the predefined range in the case of, this processor sends order, right
Air-conditioning is controlled or alerts, in order to user can find in time.By above-mentioned steps, reach air-conditioning power supply voltage
Carry out the purpose detecting and protecting, it is achieved thereby that reduce the economic asset loss technique effect of user, and then solve relevant
The technical problem that air conditioning for automobiles power supply voltage can not be detected and protects in technology.
When the supply voltage that detects situation not within the predefined range occurs, in order to realize user it can be found that therefore
Barrier, this detection method also includes: display module alerts according to mentioned order.By display module, that can think over is aobvious
Show whether fault occurs, make user find fault intuitively.
Under normal circumstances, during starting of air conditioner, can go out to have certain noise, by display module, fault can be entered
Row display, alternatively, above-mentioned display module includes at least one of: charactron, LED.By numeral method device, Ke Yixian
Show the failure code of power supply, by LED, trouble light can be shown, make user find fault more intuitively.Need explanation
It is that this indicating template can also is that other the device that can be used in display.
The power supply used air-conditioning to realize voltage detection unit detects, and needs to corresponding voltage
Reason, based on this, the alternating current voltage of the power supply that above-mentioned air-conditioning is used by above-mentioned voltage detection unit is converted to above-mentioned processor energy
Enough magnitudes of voltage accepted, wherein, above-mentioned magnitude of voltage is judged whether in above-mentioned preset range by above-mentioned processor.
It addition, in order to allow users to open easily or cancel voltage detection unit, alternatively, this detection method is also wrapped
Include: key-press module is cancelled or starts the detection function of above-mentioned voltage detection unit.By the way of button, user can be timely
Open or cancel voltage detection unit.Owing to display module can show failure code, it is therefore possible to use the mode profit of button
Malfunction coefficient is cancelled with button.And use the mode of button to exit fault protection scheme.
Alternatively, in the case of the magnitude of voltage of above-mentioned power supply is not in above-mentioned preset range, above-mentioned key-press module starts
The detection function of above-mentioned voltage detection unit；In the case of the magnitude of voltage of above-mentioned power supply is in above-mentioned preset range, above-mentioned press
Key module cancels the detection function of above-mentioned voltage detection unit.
Under normal circumstances, user will not stare at the display module of air-conditioning always, in order to be able to cause the attention of user, sends out in time
Existing fault, alternatively, the method also includes: by alarm times, alarm notifies that the detection function of above-mentioned voltage detection unit is
Cancel or start.Such as, being cut-in voltage detector unit by setting alarm times as 3 times, alarm times is to be for 1 time cancellation electricity
Pressure detector unit.It should be noted that the warning function of alarm can also continuously be reported to the police, according to the duration table reported to the police
Showing unlatching or the cancellation of voltage detection unit, e.g., long-time warning is to cancel, and the short time is for opening.
When air-conditioning on automobile is opened, it is generally required to open the electromotor of automobile, the startup of electromotor is relied on to be turned by kinetic energy
Turn to electric energy could air-conditioning be powered, but in this case, electromotor can run in running unavoidably
Fault, causes supply voltage unstable, and it can use too high or too low voltage to be powered caravan air-conditioning unavoidably, optional
Ground, above-mentioned air-conditioning is air conditioning for automobiles.Further, this automobile is caravan.By above-mentioned voltage detection method, reach automobile
Air-conditioning power supply voltage carries out the purpose detecting and protecting, it is achieved thereby that reduce the economic asset loss technology effect of user
Really, and then solve the technical problem that air conditioning for automobiles power supply voltage can not be detected and protects in correlation technique.Can
Selection of land: in the case of the supply voltage value of above-mentioned air conditioning for automobiles is not in above-mentioned preset range, on load control module controls
The load device stated on air conditioning for automobiles quits work.
When processor judges the voltage of this caravan air-conditioning not within the predefined range, processor enters supply voltage error protection
Pattern, above-mentioned load device includes at least one of: compressor, blower fan, waits all caravan air conditioner load to quit work at once,
And then reach to protect air-conditioning, reduce the effect of user's loss.
In conjunction with object lesson, as in figure 2 it is shown, user can be by the combination pre-set of caravan air-conditioning key-press module 50
Button carries out starting or shielding this supply voltage defencive function pattern, and can confirm it is to start also by the alarm number of times that pipes
It is to shield this supply voltage defencive function pattern, if user starts this supply voltage defencive function, voltage detection unit 20
By power supply 10 carries out the real-time detection of voltage, different ac voltages can be converted into process by this voltage detection unit 20
The magnitude of voltage that device 30 can receive, processor 30 is by carrying out Real-time Collection to the magnitude of voltage of voltage detection unit 20, if adopted
The magnitude of voltage of collection larger or smaller than the protection magnitude of voltage set, then judges the power supply electricity of this caravan air-conditioning within continuous time
Pressure is for non-predetermined range of voltages, and processor 30 enters supply voltage fault protection scheme, load control module 60 will to compressor,
All caravans air conditioner load such as blower fan quits work at once, the double eight numeral method failure codes on display module 40, corresponding
Mode indicating lamp under pattern carries out flash for prompting.Remind user's confirmation as early as possible process, it is to avoid produce bigger potential safety hazard and
Property loss.If after supply voltage protection occurs, when processor 30 detects that within continuous time voltage meets load fortune
The voltage range of row, then processor 30 will enter the mode of secession of supply voltage protected mode, the pattern instruction under associative mode
Lamp does not flashes, double eight numeral method failure codes of display module 40, after need to being shown by user key-press cancellation failure code,
Side exits supply voltage protected mode completely.All caravans air conditioner load such as compressor, blower fan can resume operation.By detection room
Whether the supply voltage of car air-conditioning is beyond the fault coverage set, failure judgement state simultaneously；And by charactron and/or LED
Display lamp carries out malfunction coefficient and informs user, allows user fix a breakdown, and protects machine, solves caravan air-conditioning power supply voltage
Detection and protection.
The invention described above embodiment, just to describing, does not represent the quality of embodiment.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
