Referring to FIG. 7 , the hollow interlayer 10 is provided with an electric louver (not shown) communicating with the outside, and the outer side of the outer glass 1 is provided with a detection module for detecting an external environment and a control coupled to the detection module. The module is controlled by the detecting module, and the detecting module includes one or more of the wind detecting module 310, the temperature detecting module 320, and the rain detecting module 330, and can be set according to the user's preference, wherein the wind is set. The detecting module 310 is disposed outdoors for detecting external wind power. When the outside wind exceeds a preset value, the wind detecting module 310 outputs Va1, and the control module receives Va1 to determine whether to open the electric blinds according to the actual situation in the room, for example, when When the outside wind is too high and the indoor oxygen concentration is low, the control module can be ventilated through the window to ventilate the room. The user can also choose whether to activate this function according to his or her preference. Similarly, the temperature detecting module 320 is disposed outside the room for detecting the temperature of the outside, and when the outside temperature exceeds a preset value (or indoor temperature), the temperature detecting module 320 outputs Va2, The control module can judge whether to open the ventilation of the electric blind according to the indoor poetry situation. For example, when the external temperature is higher than the indoor predetermined temperature, the control module can be used to open the window for ventilation, thereby saving the use of the central air conditioner and having a certain energy saving effect. When the outside temperature is too low and the indoor temperature is higher than the preset temperature, the control module can also be used to control the electric blinds to open the window and ventilate, which can reduce the temperature of the room and save energy. Similarly, the rain detection The module 330 is also disposed outdoors for detecting the humidity of the outside. When the outside humidity exceeds a preset value (or indoor humidity), the rainwater detecting module 330 outputs the humidity detecting signal Va3, and the controller can be turned on by the controller to perform ventilation, thereby increasing Indoor air humidity, when the indoor is too humid, and the outdoor humidity is less than the indoor humidity, you can also open the electric blinds through the controller to change the air, thereby increasing the indoor air drying.

When the AND circuit receives Va1 and Va2 simultaneously, the control module controls the electric shutter to open. It means that the outside temperature is higher, but the wind is larger. At this time, if the glass curtain wall is opened, the indoor and outdoor air are continuously ventilated, and heat exchange occurs to keep the room dry. At this time, it is not necessary to turn off the glass curtain wall to turn on the air conditioner; In addition, when the outside temperature is high and the wind is small, there will be ventilation problems indoors and sultry; in addition, when the outside temperature is low and the wind is large, opening the glass curtain wall will make the room cold; likewise, when the outside temperature is low, When the wind is small, opening the glass curtain wall will make the room cold; based on the above four cases, the control module is only outside. Higher temperature, wind and the large glass walls open, in which case no air conditioning can be energy saving.

Moreover, when the wind detecting module 310 and the rain detecting module 330 work simultaneously, the wind detecting module 310 and the rain detecting module 330 not only transmit the wind detecting signal Va1 and the humidity detecting signal Va3 to the control module, and at the same time, the wind detecting module 310 and The rainwater detecting module 330 is further coupled to an AND circuit, and the input end of the AND circuit is configured to receive the wind detecting signal Va1 and the humidity detecting signal Va3. When receiving Va1 and Va3 at the same time, the control module controls the electric shutter to close, because, When the outside is raining, there is a possibility that rainwater enters the room through the glass curtain wall. At this time, if accompanied by wind, the rainwater must enter the room through the glass curtain wall; the wind detection module 310 can receive the wind when the ambient wind is large. When the pressure is large, the wind detecting signal is output, and the rain detecting module 330 can output the wind detecting signal when the environment is raining, that is, when the humidity of the environment is detected is large, when the two signals are complete, the control module controls the electric shutter to close, if the above When the three detection modules work simultaneously, the electric shutters are closed with a higher priority than the electric blinds. Kai, to prevent rain water into the room.

Referring to FIG. 8 , the wind detecting module 310 is configured as a monostable trigger circuit. When the pressure applied to the strain gauge R is large, the resistance of the strain gauge R is reduced, and the resistance strain gauge R and the potentiometer W1 are Common node generates low level The electrical signal, at this time, using the characteristics of the monostable trigger circuit, its output will output a high level.

Referring to FIG. 9, the temperature detecting module 320 is configured as a monostable trigger circuit. When the ambient temperature of the temperature sensitive resistor RT is high, the resistance of the temperature sensitive resistor RT is reduced, and the temperature sensitive resistor and the potentiometer W2 are common. The node generates a low-level voltage. At this time, the output of the monostable trigger circuit outputs a high level.

Referring to FIG. 10, the rainwater detecting module 33043 is set as a monostable trigger circuit. When the humidity of the humidity sensitive resistor YCG is large, the resistance value of the humidity sensitive resistor YCG is reduced, and the humidity sensitive resistor YCG and the potentiometer W3 are The common node generates a low-level electrical signal. At this time, using the characteristics of the monostable trigger circuit, the output of the monostable trigger circuit outputs a high-level signal.

At the same time, the signal DIR-A and the signal PWM are directly compared with the output signal PWM-B, due to the reverse action of the NOT circuit U3A. Therefore, the signal PWM-A and the signal PWM-B always have one output of 0, wherein the signal DIR-A (signal DIR) is the motor steering control signal outputted by the single chip AT89C51.

Referring to FIG. 12, the driving unit 350 is coupled to the commutating unit 340 for receiving the signals PWM-A and the signal PWM-B and the signals DIR-A and DIR-B. The driving unit 350 includes an H-bridge driving circuit, and the first a control unit and a second control unit.

When the DIR-A is 1, the switching device Q3 is turned on, and the signal PWM-A is 0 due to the state of the signal DIR-A, and the signal PWM-B is valid. The signal DIR-B is inverted with the signal DIR-A, and the signal DIR-B is 0. At this time, the switching device Q7 is turned off. Only the control signal PWM-B can be used to speed the motor. If the motor is defined as forward rotation at this time, when the signal DIR-A is 0, the switching device Q3 is turned off, the switching device Q7 is turned on, the signal PWM-A is valid, and the signal PWM-B is 0, and the motor is reversed.
