Show unlatching or the cancellation of voltage detection unit, e.g., report to the police as cancelling for a long time, the short time is to open.
When air-conditioning on automobile is opened, generally require the electromotor opening automobile, rely on the startup of electromotor to turn kinetic energy
Turn to electric energy air-conditioning could be powered, but in this case, electromotor can run in running unavoidably
Fault, leads to supply voltage unstable, and it can be powered to caravan air-conditioning using too high or too low voltage unavoidably, optional
Ground, above-mentioned air-conditioning is air conditioning for automobiles.Further, this automobile is caravan.By above-mentioned voltage check device, reach to automobile
The purpose that air-conditioning power supply voltage is detected and protected, 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 protected in correlation technique.Can
Selection of land：In the case that the supply voltage value of above-mentioned air conditioning for automobiles is not in above-mentioned preset range, in load control module control
The load device stated on air conditioning for automobiles quits work.
Not within the predefined range, processor enters supply voltage error protection to the voltage judging this caravan air-conditioning when processor
Pattern, above-mentioned load device includes at least one of：Compressor, blower fan, wait all caravan air conditioner load to quit work at once,
And then reach protection air-conditioning, reduce the effect of user's loss.
In conjunction with specific example, as shown in Fig. 2 user can pass through the combination pre-setting of caravan air-conditioning key-press module 50
Button is started or is shielded 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 is carried out with the real-time detection of voltage, different ac voltages can be converted into processing by this voltage detection unit 20
The magnitude of voltage that device 30 can receive, processor 30 by Real-time Collection is carried out to the magnitude of voltage of voltage detection unit 20, if adopted
The magnitude of voltage of collection is larger or smaller than the protection magnitude of voltage of setting within continuous time, then judge the power supply electricity of this caravan air-conditioning
Press as non-predetermined range of voltages, 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 that confirmation is processed as early as possible, it is to avoid produce bigger potential safety hazard and
Property loss.If after supply voltage protection occurs, meet load fortune when processor 30 detects voltage within continuous time
Row voltage range, then processor 30 will enter supply voltage protected mode the mode of secession, under associative mode pattern instruction
Lamp does not flash, 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 detecting room
Whether the supply voltage of car air-conditioning is beyond the fault coverage setting, failure judgement state simultaneously；And pass through charactron and/or LED
Display lamp carries out malfunction coefficient and informs user, allows user to fix a breakdown, and protects machine, solves caravan air-conditioning power supply voltage
Detection and protection.
