First, this utility model is powered and is inputted positive binding post X1 and main power input negative binding post X2 acquirement by main power, and remember that the negative binding post X2 of main power input is of the present utility model with reference to ground, in the above, all of ground connection is connected all referring to binding post X2 negative with main power input.Simultaneously in order to meet the supply voltage (5V or the 3.3V) reality less than air-conditioner controller running voltage (12V or 24V) of microcontroller U1 demand, power transfer module U2 is used to change voltage.Power supply indicator L6 is used for indicating whether power supply powers normally, and when on and off switch S3 connects, power supply indicator L6 lights, and controls controller and is powered.
Background light on background signal controlled switch S1 Guan Bi air-conditioner controller obtains power supply and will be lit.Ignition switch on ignition control switch S2 simulation real vehicle, ignition control switch S2 closes simulation ignition switch and opens, and ignition control switch S2 disconnects simulation ignition switch and closes.
Air-conditioner controller can carry out PWM control by transistor Q1 controls end and regulate, by the actual voltage value obtained from air quantity feedback connection terminal J1, the air quantity wanted that PWM duty cycle reaches.Voltage at air quantity feedback connection terminal J1 realizes the brilliance control to air quantity display lamp L3, simulates the control of the wind speed to aerator with this, and air quantity display lamp L3 brightness the highest expression blower speed is the highest.Microcontroller U1 gathers the dividing potential drop at the air quantity feedback connection terminal J1 that resistance R6 obtains to differentiate the gear residing for air quantity simultaneously.
Compressor control binding post J3 obtains high-level compression machine and controls relay K 1 just Guan Bi, and compressor display lamp L4 is just lit.Microcontroller U1 just can obtain the dividing potential drop obtained from resistance R4 simultaneously, just can learn compressor start.
Rear defrosting binding post J4 is in high level state usually, and the binding post J4 that defrosts after defrosting after once needing to start will be pulled low, and so rear defrosting controls relay K 2 and will close, and rear defrosting display lamp L5 will be lit.
Air-conditioner controller has a pull-up resistor connected with vaporizer simulation potentiometer RV1 by evaporator temperature sensor binding post J9, and inside air-conditioner controller, gather the dividing potential drop on vaporizer simulation potentiometer RV1.Different resistances will obtain different partial pressure value and vary with temperature to simulate evaporator temperature sensor resistance with this.Just be can determine that the temperature value of vaporizer by the voltage got, this dividing potential drop also can be passed to microcontroller U1 and obtain temperature value through corresponding process simultaneously.
The actuating motor of on-board air conditioner is divided into the both types without feedback that band feeds back.Band feedback motor its be connected at outfan and a potentiometer, the change of outfan angle can be reflected as getting on potentiometer the change of voltage.As long as the two ends of potentiometer being connected the power supply of certain voltage, centre tap just can represent the position signalling of motor.Have only to two extreme positions, and all limited locations, so this motor to be ensured without the voltage fed back and turned over the regular hour, be parked in the two extreme position with regard to one surely.Pattern motor M1 and changes in temperature motor M2 is because wanting relatively accurate control position, so using the motor that band feeds back, microcontroller U1 just can know that motor location by the value obtaining feedback voltage, obtains the gear residing for pattern or changes in temperature further.And circulation motor M3 does not has this requirement, it is possible that use non-feedback motor, thus need to gather the positive J18 of circulation motor and circulation motor and drive control voltage above negative binding post J19 to judge motor whether action.In order to meet both control modes simultaneously, so having more the direct part gathering motor driven voltage signal with circulation motor M3 connection terminal portion than pattern motor M1 and changes in temperature motor M2 connection terminal portion.
During work, microcontroller U1 judges the gear of air quantity by gathering the voltage of R5, and shows in numeral method module D1；Microcontroller U1 calculates temperature value by gathering the voltage got on RV1 simultaneously, and shows in numeral method module D1；Microcontroller U1 can by gather the circulation feedback connection terminal J17 place of circulation motor M3 voltage or gather circulation motor drive positive binding post J18, circulation motor to drive the driving voltage at negative binding post J19 to judge on-board air conditioner is in interior circulation or outer circulation and circulates display lamp L2 by control and react；And microcontroller U1 can gather the feedback voltage of changes in temperature motor feedback binding post J14 to judge the changes in temperature gear of on-board air conditioner, and is shown in numeral method module D1；The feedback voltage of the drainage pattern motor feedback binding post J11 of microcontroller U1 meeting simultaneously judges the pattern residing for on-board air conditioner, and shown by mode indicating lamp group L1, which pattern current air-conditioning is in, microcontroller U1 will control to light blow face display lamp L11, blow face blow foot display lamp L12, blow foot display lamp L13, blow foot before defrost that display lamp in display lamp L14 and front defrosting display lamp L15；Buzzer B1 is configurable function, is configurable to during compressor work ring, and is configurable to ring when evaporator temperature is too low, it is also possible to be configured to the Shi Xiang etc. that the do not works when that compressor should working.
