Principle of work: infrared receiving tube is just relative with infrared transmitting tube in the sensor that the utility model adopts, because infrared light is different with airborne absorption coefficient in water, thereby also is different by the light intensity behind the empty G﹠W.When not having rainwater by receiving tube and power valve middle, receiving tube output high level; When rainwater during by receiving tube and power valve middle, receiving tube has received this variation, and output low level just can detect in view of the above whether rainwater is arranged.
Voltage comparator is an integrated transporting discharging nonlinear application circuit, and it is compared an analog quantity voltage signal and one with reference to fixed voltage, the two amplitude equate near, output voltage will produce transition, corresponding output high level or low level.Comparer can be formed the nonsinusoidal waveform translation circuit and be applied to fields such as analog and digital signal conversion.Transport property when Ui＜Ur, amplifier output Uo high level, when Ui＞Ur, amplifier output Uo low level.Therefore, be the boundary with Ur, when input voltage Ui changed, output terminal reflected two states, noble potential and electronegative potential.Integrated voltage comparator LM111 can become binary signal with analog signal conversion, promptly has only the discrete signal of high level and low level two states.Its characteristics: the open-loop gain than integrated transporting discharging is low, and offset voltage is big, and common-mode rejection ratio is little; But its response speed is fast, and the propagation delay time is short, and need not add amplitude limiter circuit and just can directly drive integrated digital circuits such as TTL, CMOS and ECL; Some chip belt load capacity is very strong, also can directly drive relay and pilot lamp.
Signal can be subjected to the interference of each side in practice, and can there be many clutter compositions in waveform, need handle waveform, and the utility model has utilized Schmidt trigger.The Schmidt trigger most important character is can input signal is shaped to the precipitous rect.p. in edge changing slowly.Simultaneously, Schmidt trigger also can utilize its hysteresis voltage to improve the antijamming capability of circuit.
Size is little, the advantage of light weight because infrared sensor has, and is installed on the telescopic clothes rack simpler; Auxiliary circuit is required to lack, can launch with direct current in low coverage, circuit is simple, stable performance.
When not having rainwater by infrared transmitting tube and infrared receiving tube middle, infrared receiving tube output high level, the P3 pin current potential of voltage comparator LM111 is greater than the P2 pin current potential of voltage comparator LM111, the P7 pin output low level of voltage comparator LM111, through the two-stage trigger to wave shaping, transistor Q1 is in cut-off state, and relay K is failure to actuate, and telescopic clothes rack is failure to actuate; When rainwater during by infrared receiving tube and infrared transmitting tube middle, intensity of illumination between infrared transmitting tube and the infrared receiving tube changes, therefore the electrical signal intensity of infrared receiving tube output also can change, output low level, the P3 pin current potential of voltage comparator LM111 is less than the P2 pin current potential of voltage comparator LM111, the P7 pin output high level of voltage comparator LM111, through the two-stage trigger to wave shaping, transistor Q1 is in state of saturation, the relay K action, drive the motor of telescopic clothes rack, clothes hanger withdrawal balcony.
A kind of flexible automatically clothes horse of rainwater of meeting of the utility model is reasonable in design, and controller is in light weight, volume is little.Utilize the absorption coefficient difference of infrared light in air and water, thus also different by the light intensity that receives behind the empty G﹠W.When the intensity of illumination of infrared beam changed, therefore the electrical signal intensity of receiving end output also can change, thereby the start-up control device sends signal.Not only practical, and bring great convenience to people's life.
