The utility model adopts four kinds of circuit to match with control device, by temperature control, wet control, smog control, and the control of irradiation degree can omnibearingly be controlled window opening device, not only can reduce labour intensity widely, increase work efficiency, and can realize the modern management of opening the door, windowing.

Fig. 1 is circuit connecting relation figure of the present utility model.

Circuit connecting relation in the accompanying drawing as previously mentioned, numeral display voltage gauge outfit cooperates four pieces of charactrons to form 3.5 digital display voltmeter heads by the integrated analog-to-digital conversion piece of large scale digital A/D7107, when the kilobit charactron shows that " 1 " and its excess-three figure place sign indicating number are completely without demonstration, represent that this voltmeter head input signal has surpassed the range upper limit, return it, when showing " 1 ", the expression input signal has surpassed lower limit.When the needs temperature is controlled, change-over switch K2 puts 2 grades, K5 and puts 1 grade, sensor RT converts variation of temperature to the variation of voltage signal, RT selects industry standard thermistor Pt100 for use, change-over circuit is made up of 2 amplifier 1IC1:A, 1IC1:B among the four high guaily unit LM324 and 1D1,1R8,1R9, RT, + 5V power supply provides the reference voltage source of 0.275V to 1IC1:A by the voltage stabilizing of current-limiting resistance 1R8 and 1D1, thermistor Pt100 serves as the negative feedback resistor of amplifier, and the variation of its resistance is by the voltage signal of 1IC1:A conversion into about 1～1.9V.In order to improve carrying load ability, added first-level buffer amplification 1IC1:B again and be opened in the measure error that different gears cause in order to remove to switch to close.Comparison circuit is made of 1IC1:C, and change-over switch K2 puts 2 grades, when K5 puts 1 grade, instrument displays temperature measured value, K2 are put 2 grades, when K3 puts 2 grades, the display setting temperature value, when measured value is lower than setting value, the high level about amplifier output 4V, make the J1 adhesive by 1R11,1D2,1BG1, the BG1 conducting, BG2 ends extremely, and J2 is positioned at 2, make FC work, motor D counter-rotating (promptly close window or close the door).Otherwise ZC work, motor just changes (promptly window or open the door), and FA2 is for closing the limit switch of window (door), and ZA2 is the limit switch of window (door).Design can guarantee that open and close can be inexcessive like this, and circuit two wet control digital display portion and temperature control are shared.When K2 puts 1 grade, can show humidity, thereby show humidity control, the low-frequency ac voltage that 2IC1:A and 2IC1:B produce in the circuit is added on the dew cell HPR through electric capacity 2C2,2C3, moisture signal is added in the inverting input of 2IC2:A, 2IC2:A and diode 2D1,2D2,2D3 constitute log compression circuit, and double rectification circuit, are used for compensating the non-linear of dew cell.2C4,2C5,2R7 elimination disturbing pulse only change its output voltage with the variation of relative humidity.2IC2:B constitutes a homophase amplifier, and 2RP2 carries out zero point to be regulated, and multiplication factor is decided with the ratio of 2R8 by 2RP3, through the relative moisture signal voltage of 2R9 output.When K2 puts 1 grade, K4 puts 1 grade, and instrument shows the moisture measurement value.When K4 puts 2 grades, the display setting value.When humidity reaches when setting value, 1IC1:D export high level, by 2R10,2D4, BG1 is ended extremely, BG2 conducting, FC work, motor reverse (promptly close window or close the door).Circuit three adopts 3QM-T2 type gas sensitive device, the resistance of gas sensitive device in clean air is set at Ra, drop to Rg behind the contact fuel gas, because the resistance of QM-T2 descends, 4BG1 ends extremely in the drawings, 4BG2 is also and then exhausted to be ended, its current collection resistance output high potential removes to control BG1, BG2, J2, makes FC get electric work by 4D1, the motor D counter-rotating, promptly realize smog control pass window, this action is still spacing by FA2.Circuit four has adopted light resistor, and when the unglazed photograph of light resistor, its resistance one is about 1500K Ω, and when illumination was arranged, its bright resistance was several kilo-ohms, and both differ bigger, and this circuit utilizes this characteristic that window opening device is controlled automatically.When daytime, light resistor was subjected to illumination, the GR value was very little, and 5BG1 does not work, and light-operated circuit is inoperative.When evening, light resistor GR is unglazed according to the time, GR is high-impedance state, the 5BG1 base potential rises, emitter stage is also exported high potential, removes to control BG1, BG2, J2, FC make the motor counter-rotating, thereby realizes the moving secretly control of closing window in sky.The utility model can also adopt manual overvide, when K5 puts 2 grades, temperature control, wet control, light-operated, cigarette control all are in closed condition, at this moment, circuit is connected hand gear, presses point driving switch ZA1, motor just changes, and presses point driving switch FA1, the motor counter-rotating can be played the effect of opening and closing door (window) equally.
