[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is a functional-block diagram of the present utility model.
[specific embodiment]
Come the utility model is described in detail below in conjunction with specific embodiment.
See also shown in Figure 1, it is a kind of full automatic vehicle air-conditioner controller described in the utility model, it includes the LCD display circuit, keyboard circuit, the vehicle interior temperature sensor, the outer temperature sensor of car, evaporator temperature sensor, temperature sensor on the CPU board, the sunlight illuminance transducer, 4 position motors, the LIN bus transceiver, it is characterized in that: also include MCU, two 6 road half-bridge drivers and power amplifier able to programme, described LCD display circuit, keyboard circuit, the vehicle interior temperature sensor, the outer temperature sensor of car, evaporator temperature sensor, temperature sensor on the CPU board, the sunlight illuminance transducer, 4 position motors, the LIN bus transceiver all is connected to MCU, and two 6 road half-bridge drivers also link to each other with MCU with power amplifier able to programme.Described MCU adopts MC9S08AW32, is 8 MCU, contains the A/D circuit of 16 path 10 bit, and FLASH is 32K, and RAM is 2K.Described two 6 road half-bridge drivers adopt NCV7708A; it has two 6 road half-bridge drivers of protection fully; 6 low side controllers and 6 high-side driver can freely dispose; and can control separately; support the control of high-end, low side and H bridge; its input is connected to MCU, and output is connected to 3 position motors.Described power amplifier able to programme adopts a slice LM2902, and its input is connected to MCU, and output is connected to 1 position motors, compressor, cooling fan and demist circuit.Described vehicle interior temperature sensor, its R0=4.852K Ω, during variation of ambient temperature, the Rt value reduces to 0.6752K Ω from 332.1K Ω from-40 ℃ to+100 ℃; The outer temperature sensor of described car, its R0=4.852K Ω, during variation of ambient temperature, the Rt value reduces to 0.6752K Ω from 332.1K Ω from-40 ℃ to+100 ℃; Described evaporator temperature sensor, its R0=4.852K Ω, R15=2.341K Ω, during variation of ambient temperature, the Rt value reduces to 0.1167K Ω from 49.5074K Ω from-40 ℃ to+95 ℃.The current location of described 4 position motors can be detected by MCU, and 4 position motors are respectively temperature turnover panel motor, central turnover panel motor, pin hole/defrosting turnover panel motor and ventilation turnover panel motor.
The vehicle interior temperature sensor signal that the utility model device collects according to detection, the outer temperature sensor signal of car, sunlight illumination sensor signal, pin hole temperature sensor signal, the fresh air temperature sensor signal, the evaporator temperature sensor signal, pressure sensor signal, the feedback signal of air door servomotor, the feedback signal of air blast, the feedback signal of ECU, the feedback signal of compressor, signal such as the speed of a motor vehicle and rotating speed, calculate through internal processes, to temperature turnover panel motor, ventilation turnover panel motor, pin hole turnover panel motor, compressor, air blasts etc. are controlled, send the air-conditioner temperature and the air quantity that adapt to present case, make the interior air of car become comfortable, allow driving variable get easily.The setting of vehicle interior temperature, the rotating speed of air blast and defrosting.Air circulation and economic model also can manually be changed by the driver and conductor.
This product is set at three sections with its internal temperature:
LO shelves: be automobile total power refrigeration;
18 ℃～29 ℃ shelves; This is the scope that is provided with of normal temperature;
HI shelves: be the automobile heating with full power.
LO shelves and HI shelves are to take into full account in heat and severe cold weather, and the driver and conductor has just carried out total power refrigeration and heating into the car, makes the driver and conductor obtain comfortable sensation rapidly.We can make amendment the built-in temperature scope according to customer requirement.
Under the normal condition, generally we think that 22 ℃ is the temperature that allows the people comfortable the most, so during the stage, press the AUTO key in the temperature of HI and LO, can reach this setting value, and this value also can answer customer requirement that it is made amendment.
In order to strengthen the reliability of this air-conditioner controller, we adopt external temperature sensor and the fresh temperature sensor mode of trans-substitution mutually that allows.That is to say that when one of them quit work when these two sensors, air-conditioning can detect made mistakes, and in start prompting client error message, but air-conditioning operate as normal still, and the sensor that has quit work replaces its function by another sensor.Only when having detected fatal error message, the air-conditioner controller close compressor quits work.
This example is intended to illustrate utility model, and limits the utility model absolutely not, and this intelligent air condition controller can be used for various vehicles to be used.
