Abstract
The invention discloses an intelligent windshield wiper which comprises a measurement control device, a windshield wiper body and a windshield washer fluid jetting device. The measurement control device is installed in an automobile, and the windshield wiper body and the windshield washer fluid jetting device are arranged on the automobile. The measurement control device comprises a microprocessor, a light beam emitting device, a light beam receiving sensor and a humidity sensor. The light beam emitting device, the light beam receiving sensor and the humidity sensor are all connected with the microprocessor. The light beam emitting device and the humidity sensor are arranged outside the automobile. The light beam emitting device is aligned to the light beam receiving sensor. The windshield wiper body and the windshield washer fluid jetting device are both connected with the microprocessor of the measurement control device. The intelligent windshield wiper can control the windshield wiper body to work according to the current light transmittance of a windshield, is not affected by any other factors, and is good in adaptability; in addition, the windshield wiper body can adjust the working frequency according to the light transmittance, small in error and high in working efficiency. The intelligent windshield wiper can also control the windshield washer fluid jetting device to jet windshield washer fluid according to the current humidity, automatically clean the windshield in non-rainy days, and ensure that the visual field for a driver is good.
Description
Technical field
The present invention relates to a kind of Vehicular device, specifically, is a kind of screen wiper and method of work thereof.
Background technology
While raining, raindrop can be low to the Windshield of automobile, make chaufeur cannot clearly observe the scene of vehicle front, must open wiper the ponding on Windshield is clear, the clear visual field of guarantee chaufeur, the generation avoiding traffic accident, but the wiper using at present all needs chaufeur manually to open work, and the frequency of operation of wiper also needs manual shift, troublesome poeration, if the force of rain diminishes, the wiper that frequency of operation is higher still impacts driver's the visual field, for fear of above-mentioned deficiency, there is automatic windshield wiper, by the water yield falling in tank, judge whether wiper works, but still there are a lot of problems in this automatic windshield wiper, when if the current speed per hour of automobile is very fast, rainwater may flow out from automobile both sides, do not fall into tank, cause the error in judgement of the water yield, affect the working effect of automatic windshield wiper, if vehicle is because the Windshield that other reasons causes is fuzzy, wiper still cannot automatic operation.
Summary of the invention
The present invention is directed to current wiper and need manual shift, troublesome poeration, automatic windshield wiper is when the speed of a motor vehicle is very fast, easily cause the error in judgement of the water yield, affect the working effect of automatic windshield wiper, cannot when other reasons causes Windshield fuzzy, carry out the problems such as work, design a kind of screen wiper and method of work thereof.
Screen wiper of the present invention, comprise the measuring and controlling that is arranged in automobile, be arranged on wiper, bath of glass jetting system on automobile, measuring and controlling comprises microprocessor, beam launcher, light beam receiving sensor, humidity sensor, beam launcher, light beam receiving sensor, humidity sensor are all connected with microprocessor, beam launcher and humidity sensor are arranged on automobile external, beam launcher alignment receiving sensor, wiper is all connected with the microprocessor of measuring and controlling with bath of glass jetting system.
The method of work of screen wiper, step is as follows:
1) microprocessor is controlled beam launcher to the light beam of light beam receiving sensor transmitting constant intensity, the intensity of light beam receiving sensor receiving beam measuring beam;
2) light beam receiving sensor sends to microprocessor by the beam intensity measuring, and microprocessor contrasts the fixed beam intensity of the beam intensity measuring and beam launcher, calculates the light transmittance of windshield;
3), if when light transmittance less than 100%, microprocessor is controlled wiper work, the ponding on cleaning Windshield, and according to the size of light transmittance, adjust the frequency of operation of wiper, microprocessor is the humidity of the current air of controlled humidity sensor measurement simultaneously;
4), if during current air humidity less than 100%, microprocessor is controlled bath of glass jetting system ejection bath of glass.
The invention has the beneficial effects as follows: screen wiper can be controlled wiper work according to the light transmittance when front windshield, be not subject to the impact of any other factor, strong adaptability, and wiper can be adjusted frequency of operation according to light transmittance, error is little, and work efficiency is high, also can control bath of glass jetting system ejection bath of glass according to current humidity, non-, Windshield is carried out to automated cleaning when rainy, guarantee that driver's seat is good.
Accompanying drawing explanation
The structured flowchart that accompanying drawing 1 is this screen wiper.
The specific embodiment
Screen wiper of the present invention, as shown in Figure 1, comprise the measuring and controlling being arranged in automobile, be arranged on the wiper on automobile, bath of glass jetting system, measuring and controlling comprises microprocessor, beam launcher, light beam receiving sensor, humidity sensor, beam launcher, light beam receiving sensor, humidity sensor is all connected with microprocessor, beam launcher and humidity sensor are arranged on automobile external, beam launcher alignment receiving sensor, wiper is all connected with the microprocessor of measuring and controlling with bath of glass jetting system.
Microprocessor is controlled beam launcher to the light beam of light beam receiving sensor transmitting constant intensity, the intensity of light beam receiving sensor receiving beam measuring beam; Light beam receiving sensor sends to microprocessor by the beam intensity measuring, and microprocessor contrasts the fixed beam intensity of the beam intensity measuring and beam launcher, calculates the light transmittance of windshield; If when light transmittance less than 100%, microprocessor is controlled wiper work, the ponding on cleaning Windshield, and according to the size of light transmittance, adjust the frequency of operation of wiper, microprocessor is the humidity of the current air of controlled humidity sensor measurement simultaneously; If during current air humidity less than 100%, illustrate that Windshield is the blurred vision being caused by other reasonses such as dusts, microprocessor is controlled bath of glass jetting system ejection bath of glass, and Windshield is cleaned.
