Description

A kind of automotive air-conditioning controller

Technical field

The utility model relates to a kind of in-vehicle air conditioner, specifically a kind of automotive air-conditioning controller.

Background technology

Along with the fast development of economy, the living standard quality of people also improves, and automobile has been the walking-replacing tool of a lot of family, and on-board air conditioner can make people all feel more comfortable in severe winter or heat.Most of on-board air conditioner is arranged by ac control circuit and controls vehicle interior temperature in the market.But it is reported, once car internal-external temperature difference is more than 6 degree, human body will produce discomfort because of thermal ataxia, suffers from air conditioner disease, is easy to the illness causing flu, fever, and current on-board air conditioner can only manually control by knob, closedown air-conditioning can be forgotten time sometimes people leave car, thus waste electric energy, not only increase cost, and cause more carbon dioxide, contaminated environment.

Utility model content

The purpose of this utility model is to provide a kind of automotive air-conditioning controller controlling precisely, effectively can save electric energy, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme:

A kind of automotive air-conditioning controller, comprise Single-chip Controlling center, temperature difference Acquisition Circuit, on-board air conditioner controller, mode switch module, display screen and GPRS module, described Single-chip Controlling center connects temperature difference Acquisition Circuit, peripheral hardware button, power module, air-conditioner controller, mode switch module, display screen and sensor circuit respectively.

As preferred version of the present utility model: the main core component at described Single-chip Controlling center be MSP430 type single-chip microcomputer.

As preferred version of the present utility model: described sensor circuit uses TX982 type microwave induction controller as the human body induction module of main control unit.

As preferred version of the present utility model: described mode switch module is for realizing the switching of on-board air conditioner intelligent thermoregulating and manual temperature.

As preferred version of the present utility model: described display screen is LCD display.

Compared with prior art, the beneficial effects of the utility model are: the utility model automotive air-conditioning controller is by the temperature difference inside and outside two temperature sensor probe vehicles, peripheral hardware button is used to remain in certain temperature range by vehicle interior temperature and the outer temperature of car, effectively decrease the discomfort that people cause because car internal-external temperature difference is excessive, and Operation system setting sensor circuit, have in car during people and just can open air-conditioning, in car nobody time automatically close, effectively save the energy, and decrease pollution.

Accompanying drawing explanation

Fig. 1 is the structured flowchart of automotive air-conditioning controller;

Fig. 2 is the circuit diagram of sensor circuit;

Fig. 3 is the circuit diagram of temperature difference Acquisition Circuit.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1-3, a kind of automotive air-conditioning controller, comprise Single-chip Controlling center, temperature difference Acquisition Circuit, on-board air conditioner controller, mode switch module, display screen and GPRS module, described Single-chip Controlling center connects temperature difference Acquisition Circuit, peripheral hardware button, power module, air-conditioner controller, mode switch module, display screen and sensor circuit respectively.

The main core component at described Single-chip Controlling center be MSP430 type single-chip microcomputer.

Described sensor circuit uses TX982 type microwave induction controller as the human body induction module of main control unit.

Described mode switch module is for realizing the switching of on-board air conditioner intelligent thermoregulating and manual temperature.

Described display screen is LCD display.

Operation principle of the present utility model is: in Fig. 2, human body sensing chip IC 2 is TX982 type microwave induction controller, be arranged on automotive interior, and effective scope of detection is arranged on about 1 meter, when there being people to enter in the spatial dimension of TX982 type microwave induction controller, will reflection echo when human body enters electric field, TX982 type microwave induction controller utilizes microwave Doppler effect, the microwave signal received is processed, the output of TX982 type microwave induction controller adopts open collector to export, the inner triode ON 10 seconds when microwave circuit has detected that people is movable in monitoring range, charge discharging resisting on C3 is fallen.555 chip IC 1 form single stabilization delay circuit, and when the 2nd pin is lower than 1/3 supply voltage, the 3rd pin exports high level, relay J adhesive, the contact J-1 adhesive of relay J, export enabling signal out to Single-chip Controlling center, in Fig. 3, temperature difference Acquisition Circuit uses two TMP36 temperature sensor IC3, IC4 is as acquisition elements, wherein sensor IC 3 is placed on outdoor, sensor IC 4 is placed on indoor, temperature signal is converted to 1 pin and 2 pins that linear voltage signal outputs to operational amplifier IC5 respectively by two temperature sensors, operational amplifier IC5 forms subtracter, subtraction is carried out to two voltage signals of input, output voltage is made to be difference V-out after subtraction, difference signal V-out is input to Single-chip Controlling center, when freezing, the temperature difference of described indoor/outdoor temperature-difference setting unit arranges scope between 1-10 degree Celsius, generally arrange 5 degrees Celsius, when heating, the temperature difference of described indoor/outdoor temperature-difference setting unit arranges scope between 2-20 degree Celsius, generally arrange 10 degrees Celsius, understand temperature regime for the convenience of the user, the LCD display of display room internal and external temperature numerical value is provided with in temperature-control circuit, single-chip computer control system and air-conditioner controller combine, share other control module resource of ac control circuit, comprise the switch/VFC of air-conditioning, Executive Module etc., also mode switch module is provided with in system, when not wanting to use this temperature difference control model can any switching laws to ordinary temp control model, convenient to operation, system is by the temperature difference inside and outside two temperature sensor detecting chambers, by peripheral hardware button, indoor temperature and outdoor temperature are remained in certain temperature range, effectively decrease the discomfort that people cause because indoor/outdoor temperature-difference is excessive.People leaves car a period of time later, human body sensing chip IC 2 in sensor circuit detects less than human body signal, automatically air conditioning for automobiles can be disconnected, reduce energy waste and environmental pollution, mode switch module, for realizing the switching of on-board air conditioner intelligent thermoregulating and manual temperature, does not need can switch to general control mode when using intelligent temperature-difference to control.
