Described micro controller system is connected with voltage, current detection circuit.
Described keyboard circuit adopts three buttons, and namely setting key, temperature add, temperature subtracts, and adopt the mode of external interrupt to come input message.When having button to press, produce external interrupt signal to the external interrupt pin, thereby make micro controller system enter interrupt service subroutine, then scan successively the I/O mouth that is connected with micro controller system in interrupt service subroutine, judging is which button is pressed, and carries out corresponding function.
Described display circuit comprises a Liquid Crystal Display, Liquid Crystal Display with its little power consumption, volume is little, displaying contents is abundant, ultra-thin light and handy plurality of advantages, obtain using more and more widely in pocket meter and low-power consumption application system.
Be connected with memory device on described micro controller system.
The beneficial effects of the utility model are:
(1) energy savings, the saving fund.Problem of energy crisis will affect the fast healthy development of China's economy, find new forms of energy will be our future the solution party to, and solar power is exactly wherein a kind of.
(2) environmental protection.The vehicle solar semiconductor air-conditioning is that the direct current (DC) that utilizes solar cell to transform drives the semiconductor chilling plate refrigeration and can not produce pernicious gas.And traditional air conditioning for automobiles utilizes burns gasoline and obtain electric energy and drive.
(3) simple in structure, cheaply feasible.The automobile solar energy air-conditioning mainly is comprised of three parts: solar panel, refrigerating part, control part.To sum up can draw a automobile solar energy air-conditioning price 3000 yuan of left and right.
(4) be convenient to install and use.No matter be that new car or used car can be installed the automobile solar energy air-conditioning easily, we only need the solar cell of film-form (existing production both at home and abroad) is attached to the ceiling of car, then wire are accessed air-conditioning and get final product.

Fig. 2 is the utility model circuit diagram.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
as Fig. 1, shown in Figure 2, a kind of solar vehicle indoor temperature regulator, comprise photovoltaic cell and micro controller system, photovoltaic cell is connected with micro controller system through Three-end voltage stabilizer 7805, be the micro controller system power supply, because the power supply voltage request of micro controller system is 5V, and the voltage that is produced by photovoltaic cell is unsettled, therefore adopt integrated three-terminal regulator spare 7805 to be the micro controller system power supply here, the limit input voltage of Three-end voltage stabilizer 7805 is 36V, require the high 3-4V of minimum input voltage specific output voltage, also to consider to export and input the watt loss that a pressure reduction brings, so generally be input as between 9-15V, because the photovoltaic cell normal operation produces voltage at 18V, therefore here in order to reduce the watt loss that between output and input, pressure reduction brings, 4 common rectifier diodes of input end series connection, to reach the purpose of step-down, micro controller system is connected to Buck conversion circuit through driving circuit, Buck conversion circuit is connected to switch circuit, micro controller system is connected with switch circuit through relay, due to the I/O mouth power-handling capability of micro controller system is weak can't the driving switch circuit, control therefore should be designed for the relay switching circuit whether semiconductor chilling plate works, this circuit is namely be used to completing this function, micro controller system is connected with temperature sensing circuit, display circuit reaches the keyboard circuit that is used for the operation micro controller system, micro controller system is connected with voltage, current detection circuit, be connected with memory device on micro controller system.
Temperature sensing circuit is connected with temperature sensor, and the kind of temperature sensor is numerous, DALLAS(Dallas when the occasion of application and high precision, high reliability) the DS1820 temperature sensor produced of company takes as own duty.Extra small volume, ultralow hardware is opened and is disappeared, and antijamming capability is strong, and precision is high, and additional function is strong, makes DS18B20 more welcome.DS1820 only need to receive on an I/O mouth of micro controller system, so because single bus is out to leak the pull-up resistor that needs an external 4.7K; As adopting parasitic mode of operation, as long as the VDD power pins is in parallel with single bus.But in program design, parasitic mode of operation will have to the state of bus some special requirements.
Keyboard circuit adopts three buttons, and namely setting key, temperature add, temperature subtracts, and adopt the mode of external interrupt to come input message.When having button to press, produce external interrupt signal to the external interrupt pin, thereby make micro controller system enter interrupt service subroutine, then scan successively the I/O mouth that is connected with micro controller system in interrupt service subroutine, judging is which button is pressed, and carries out corresponding function.
Display circuit comprises a Liquid Crystal Display, Liquid Crystal Display with its little power consumption, volume is little, displaying contents is abundant, ultra-thin light and handy plurality of advantages, obtain using more and more widely in pocket meter and low-power consumption application system.
Solar energy shines on photovoltaic cell, produces vdc by photovoltaic cell.On the one hand due to driven a vehicle or the former so vdc that produce of weather more unstable, need on the other hand to carry out MPPT maximum power point tracking and control, so will pass through the DC/DC changer, become the operable galvanic current of semiconductor devices source.
At first the voltage that photovoltaic cell produces pass through Three-end voltage stabilizer 7805, and the stable DC voltage that produces 5V is powered to micro controller system, at first makes micro controller system work.Micro controller system carries out initialization to each several part, makes output voltage increase gradually thereby then change the PWM dutycycle, carries out simultaneously voltage, current detecting, as feedback signal, makes the output voltage stabilization of BUCK circuit at 12V.Wherein, the variation of PWM dutycycle is decided according to the electric current and voltage of current BUCK circuit by the MPPT algorithm, realizes thus MPPT maximum power point tracking, makes the solar panel horsepower output maximum.
Read at last the temperature of current environment by temperature sensor, then judged whether setting, if Temperature Setting is arranged, compare with setting value, when higher than setting value, to semiconductor devices energising action, control the work of semiconductor devices, reduce vehicle interior temperature; During lower than setting value, add counter-current to semiconductor devices when vehicle interior temperature, semiconductor devices is heated, the rising vehicle interior temperature is to reach the effect of controlling temperature in car.If pressing the system default scheme without the temperature setting rule processes.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
