Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but be not intended to limit the scope of the present invention.
Embodiment：A kind of automobile intelligent wiper, including infrared Raindrop sensor module 1, motor drive module 3, windscreen wiper
Motor 4, wiper 5, motor message monitoring modular 6 and controller module 2, the infrared Raindrop sensor are mounted in automobile
Portion, the infrared Raindrop sensor module are messaging in the controller module, and the controller module is messaging in the motor and drives
Dynamic model block, the motor drive module communication and the rain shaving electrical machine, the wiper is mounted on the rain shaving electrical machine, described
Motor message monitoring modular is mounted on the wiper, and the motor message monitoring modular is messaging in the controller module.
The infrared Raindrop sensor module includes transmitting module and receiving module, and the transmitting module includes multi-harmonic-oscillations
Device and LED RF transmitters, the multivibrator are made of 555 timers and several resistance capacitance elements, institute
It states receiving module and includes photodiode, bandpass filter, frequency divider and 51 microcontrollers.
The operation principle of the infrared Raindrop sensor module is：Infrared Raindrop sensor module section is mainly by transmitting mould
Block and receiving module composition, the main chip of motor part is made of 74LS125.Due to using infrared ray in the design, and
Transmitting module is mainly that receiving module provides enough light radiant fluxs, therefore transmitting module is infrared by multivibrator and LED
Line transmitter, the multivibrator are made of 555 timers and several resistance capacitance elements, are driven by 555 timers
It is dynamic.The core of transmitter is oscillator, and multivibrator is a kind of self-maintained circuit, and the circuit is after being powered up without outer
Add trigger signal with regard to the rectangular pulse or square wave of certain frequency and amplitude can be generated, generally by integrated circuit phase inverter, NAND gate,

The multivibrator formed for 555 timers is driven infrared transmitting tube, then received by receiving module, photodiode
The signal received is limited in certain frequency through bandpass filter, then divided device is divided, and pulse signal is made to become millisecond
The order of magnitude, and then motor is controlled by microcontroller.
The infrared Raindrop sensor module is mounted on the windshield towards on the side of driver's cabin.Raindrop are fallen
Frequency on windshield
Infrared Raindrop sensor module senses the reflection and refraction that the size of rainfall mainly utilizes light by windshield
Principle, Fig. 2 are the refraction of light and reflection schematic diagram.It is understood that the big medium of refractive index is optically denser medium, small Jie of refractive index
Matter is optically thinner medium.And the optical index size of glass, water and air is glass>Water>Air.When light is by optically denser medium directive light
When dredging medium, refraction angle is more than incidence angle, and when incidence angle increases to a certain numerical value, refraction angle is up to 90 degree, at this time in light
Refracted light will not be occurred, that is, be totally reflected by dredging in medium.
According to above-mentioned optical principle, if LED RF transmitters is allowed to be more than 42 by incidence angle.Less than 63.It (can be according to reality
Border situation fine tuning) windshield, the infrared light total reflection formed in this way are injected, reflected ray is all received by photodiode.
When not having contacting rain water windshield, infrared ray is emitted from the LED in Raindrop sensor to windshield, the infrared ray of transmitting leads to
It crosses to reflect from windshield and be received by the photodiode in sensor, rainfall is calculated, and be converted into according to reflectivity
Electric signal is controlled, and specific works state is as shown in Figure 3.When rain, reflection light weakens, and rainfall is bigger, folding
It is more to penetrate (scattering) light, reflection light weaken, therefore the photodiode of Raindrop sensor only receive not spread it is red
Outer light, specific works state are as shown in Figure 4.
