Referring to Fig.1, the air-conditioning indoor and outdoor machine Wiring detection method of the embodiment of the present invention is vehicle-mounted suitable for air condition with camion
Air conditioner is mountable on motor vehicle, such as automobile, and is powered by Vehicular accumulator cell for its outdoor unit and indoor unit, and room
The electric energy of interior machine is accessed through outdoor unit.
In an embodiment of the present invention, which includes:
Step S100, the voltage value at the low-voltage power supply end and the voltage value at the high voltage supply end are detected；
Indoor pusher side electric-controlled plate, indoor heat exchanger, indoor fan, in some on-board air conditioners are usually provided in indoor unit
In, the structures such as PTC electric heater are additionally provided in indoor unit, be usually provided on indoor pusher side electric-controlled plate indoor machine controller,
The components work electrically-controlled component such as communicating circuit, and control indoor heat exchanger, indoor fan.In indoor unit, electric-controlled plate, interior are changed
The operating voltage of the power loads such as hot device and indoor fan is not quite similar, it is therefore desirable to provide different supply voltages.
It is understood that outdoor unit is the power supply of its electric-controlled plate by battery, or is exported after being converted into high pressure to room
Other power loads such as heat exchanger of outer machine.The power supply of the indoor unit of on-board air conditioner is to be provided by outdoor unit, namely be set to
Power supply unit in outdoor unit directly exports the voltage of battery, or exports after being converted into high pressure to the corresponding use of indoor unit
Electric loading.
Specifically, the indoor unit of air condition with camion has low-voltage power supply end and high voltage supply end, the air condition with camion
Outdoor unit has low-voltage output and high-voltage output end, and the indoor unit of the air condition with camion is supplied by low-voltage power supply end and high pressure

In the present embodiment, the low-voltage power supply end of indoor unit is that the power supply output end through outdoor unit is directly connect with power supply
, for accessing low pressure, such as 24V, 36V etc., for providing operating voltage, high pressure to indoor machine controller, communicating circuit etc.
Feeder ear then needs after the booster circuit of outdoor unit is boosted power supply, then accesses the high pressure after boosting, such as
200V, for the components such as indoor heat exchanger, indoor fan provide operating voltage namely low-voltage power supply terminate into voltage it is far small
Voltage in high voltage supply end.This allows for the high voltage supply end of indoor pusher side, low-voltage power supply end and ground terminal and outdoor unit
It needs to connect one to one between corresponding output end and ground terminal, once connection error, then may not have plant-grid connection, or
On high-tension side voltage accesses to low-voltage power supply end, and the voltage of low-pressure side accesses to high voltage supply end, so that the electricity consumption of low-pressure side
It loads the overtension born and burns, and on high-tension side power load then can not normally start because of the brownout of access
Work.
To prevent from causing indoor unit to damage after low-voltage power supply end, high voltage supply termination are wrong, the present embodiment is normal in air conditioner
Before opening work, when carrying out air-conditioning indoor and outdoor machine wiring detection, the virtual voltage at high voltage supply end is the boosting electricity of outdoor unit
Voltage before road is not boosted then exports after needing to be boosted circuit consumption.Only after air-conditioning indoor and outdoor machine wiring detection, institute
Wired connection is correct and after receiving air-conditioning open command, and the booster circuit of outdoor unit can just work, and the power supply electricity accessed
Pressure boosts to the supply voltage at high voltage supply end, can prevent the power supply line in indoor machine and outdoor unit in this way and between data line
It does not connect, and there are the voltage output for high-voltage output end when wiring dislocation, occur to low-voltage power supply end or indoor communication electricity
Road, and damage late-class circuit.And the high voltage supply before not boosting terminate into voltage can because booster circuit itself consumption
(diode is usually provided in booster circuit, so that the voltage of booster circuit output is power supply voltage-pipe power consumption pressure,
That is 24V-0.7V), and it is less than the voltage at low-voltage power supply end, therefore can be by detecting low-voltage power supply end, high voltage supply end both threads
Virtual voltage, and the voltage both compared is judged.If detecting high voltage supply end actual voltage ratio, low-voltage power supply end
Virtual voltage is high, then the supply lines misconnection being judged as between indoor unit and outdoor unit, namely the wiring at high voltage supply end connects at this time
It is connected to the low-voltage output of outdoor unit, and the wiring at low-voltage power supply end is then connected to the high-voltage output end of outdoor unit.
The present invention will test by detecting the voltage value at the low-voltage power supply end and the voltage value at the high voltage supply end
The voltage value at low-voltage power supply end and the voltage value at high voltage supply end be compared, when the voltage value at the low-voltage power supply end is less than
When the voltage value at the high voltage supply end, it is determined that wiring faults between the indoor unit and outdoor unit.The present invention can be in group
First time after replacement indoor unit perhaps outdoor unit or to on-board air conditioner in use, overhaul after installing on-board air conditioner
It afterwards reconnects power supply line, ground terminal and connection between outdoor unit and indoor unit, normally starts work in air conditioner
Before work, anti-wrong detection is carried out.The present invention is solved when there is picture and text to instruct or instruct without picture and text, asking for wiring dislocation occurs
Topic.Also, the present invention carries out fool proof operation without different joint styles, can quickly and easily realize that wiring detects,

It should be noted that in practical application, needing to supply by high voltage supply line, low pressure between outdoor unit and indoor unit
4 electric wire, ground line and connection routes are attached.When detection do not boost before high voltage supply terminate into voltage it is small
Voltage in low-voltage power supply end can be determined when the voltage for detecting low-voltage power supply end is greater than the voltage at high voltage supply end
The wiring of at least voltage output end of low-voltage power supply end and outdoor unit is that connection is correct.However indoor unit also needs to pass through connection
It is likely present when the voltage value at low-voltage power supply end is greater than the voltage value at the high voltage supply end with outdoor unit communication connection

Wiring is correct between indoor unit and the outdoor unit.
Wherein, preset voltage value can be set to 24V, or be greater than 24V, but be less than indoor unit 24V power supply system most
Big voltage bearing value.If the high voltage supply end of indoor unit and the high-voltage output end line of outdoor unit are correct, communication between the two
The line of line is also correct, then the voltage value at the high voltage supply end detected at this time is raised, and the electricity at high voltage supply end at this time
