Five. the specific embodiment

As shown in Figure 1, a kind of chance wind and rain closes the window control device automatically and comprises deceleration device, transmission device, switch 1, rainwater inductor 2, KA ₁Relay 3, K ₁On move with the hand switch 4, K ₂Set aside drag switch 5, motor 6, it also comprises KA ₂Relay 7 or KA ₇Relay 7 and NTC ₁ Thermal resistor 8, NTC ₂ Thermal resistor 9, R ₁Resistance 10, amplifying circuit; With a KA who surveys the control of wind speed circuit ₂Relay 7 is in parallel with rainwater inductor 2 and switch 1, and and KA ₁Relay 3 signal of telecommunication ends connect, and survey the KA of wind speed circuit control ₂Relay 7 conductings, control KA ₁The A of relay 3 and A ₁End is in connection status, motor 6 forward rotation, A and A ₂End is in open-circuit condition, realizes impelling window to close by deceleration device, transmission device that motor 6 connects, surveys the KA of wind speed circuit control ₂Relay 7 disconnects, control KA ₁The A of relay 3 and A ₁End is in open-circuit condition, A and A ₂End is in connection status, and motor 6 backward rotation realize impelling window to open by deceleration device, transmission device that motor 6 connects, when window moves to certain state of opening or closing, touch K ₁On move with the hand switch 4 or K ₂Set aside drag switch 5, motor 6 is open-circuit condition and quits work.

With reference to Fig. 2, the KA of described survey wind speed circuit control ₇Connect between the relay 7 one end ground connection, the other end and constant-current source and be exposed to airborne NTC ₂ Thermal resistor 9 is not exposed to airborne NTC ₁ Thermal resistor 8 and KA ₇Relay 7, be exposed to airborne NTC ₂ Thermal resistor 9 parallel connections.NTC ₁ Thermal resistor 8 is not exposed in the air, is exposed to airborne NTC ₂ Thermal resistor 9 is subjected to Influences on Wind Velocity, and its resistance becomes big because of wind speed becomes big resistance temperature step-down resistance, realizes that then resistance is directly proportional NTC with wind speed ₂Its resistance of thermal resistor 9 (be in relative air do not flow in) and wind speed influence not quite, thereby make NTC ₁ Thermal resistor 8, NTC ₂ Thermal resistor 9 parallel connections and external constant-current source, process NTC ₂It is big that the electric current of thermal resistor 9 becomes, and produces enough big electric current and cause relay 7 work.This second way is complicated than Fig. 1, but effect is also better.
