Description
Technical field
The utility model relates to the control circuit of its various duties of control in the full automatic vehicle air conditioner.
Background technology
Exportable cold wind of motorcar air conditioner and hot blast are to regulate the temperature in the car.Its various duties are by manually operated, still are the degree big and little, door opening of hot blast, air quantity such as output cold wind, all by manually finishing.This brings burden to the driver, can disperse driver's energy, for traffic safety hides some dangers for.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of control circuit that can avoid the full automatic vehicle air conditioner of above-mentioned deficiency, it can according in the car, the outer temperature of car sends instruction, controls the various duties of air conditioner automatically.
The purpose of this utility model is achieved in that the automobile self-contained air-conditioner mainly is made up of compressor, damper system and control circuit etc., control circuit is by sensor (comprise car inner sensor, car outer sensor, cooling-water temperature sensor, sunlight sensor advance, gas sensor), scrambler, the A/D processor, button, microprocessor, comparer, blower control, PWM controller, the air door servomotor, back defrosting relay, compressor controller, LCD shows, interface circuit, light emitting diode is formed.The sensor output terminal connects the input end of A/D processor, and the output of A/D processor connects CPU (microprocessor), realizes the temperature acquisition of each temperature, and CPU carries out that data compare, judgement, computing.Output is connected the CPU input to scrambler with button, the output of CPU is connected with interface circuit, interface circuit output connects compressor controller, back defrosting relay, light emitting diode, by scrambler with press the defrost duty of relay, light emitting diode of key assignments fan blower wind speed, air door pattern, preset temperature and compressor, back.The CPU output terminal connects the blower control input end by comparer, realizes the vector controlled of fan blower, makes the interior air-supply of car more comfortable, nature.The PWM output of CPU drives the air door servomotor by pwm driver, constituting of damper system, driven by servomotor worm screw, worm screw and spiral gear engagement, spiral gear and several gears mesh the composition gear train assembly successively, realize slowing down, last gear in the gear train assembly and air door engagement have moving contact on last gear, on the change resistance track of potentiometer, as the input contact of potentiometer, the output termination CPU of potentiometer does computing to output signal.Make air-conditioning air door follow procedure and operation result adjust the pattern of wind pushing temperature and air-supply automatically.The output of CPU also will connect the input that LCD shows, the duty of air-conditioning is presented on the LCD intuitively.Binding operation and the CPU sampling, logic analysis, computing of automobile automatic air condition controller by man-machine interface reaches the air-conditioning duty of control automatically, makes the hommization of air-conditioning work more comfortable.
The utility model is compared with the prior art scheme, has the following advantages: it can according in the car, the outer temperature of the car duty of regulating air conditioner automatically, do not need manual intervention, the driver is freed the steering vehicle of concentrating one's energy from drive.
