Description
Technical field
The present invention relates to the Automobile Products field, particularly a kind of Intelligent window wiper.
Background technology
While raining, people drive to travel and on the way can start windshield wiper and remove rainwater on glass, facilitate the driver to see road conditions clearly.But need to start manually windshield wiper, windshield wiper could be worked at every turn, and the each work-hours of windshield wiper is all fixed.Because each rainfall that rains is uncertain, when rainfall is large, rainwater has blocked sight line, need to start continually windshield wiper, has had a strong impact on driver driving; Rainfall hour, start after windshield wiper only need scrape back and forth several under just, but it must arrive the steady job time and just quits work.Wiper can not hommization, intelligentized work brings a lot of inconvenience and trouble to drivers, and very easily causes traffic accident rainy day thus.
Summary of the invention
The technical matters that the present invention solves is to provide the Intelligent window wiper control circuit of a kind of automatic control rain brush work-hours and state.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of Intelligent window wiper control circuit, be provided with pressure sensor, timer, control chip, rain brush driving circuit and storage battery in described control circuit, wherein accumulator output end is connected with the input end of timer, control chip, rain brush driving circuit respectively, the mouth of pressure sensor is connected with the control chip input end, timer and control chip interconnection, the control chip mouth is connected with the rain brush driving circuit input end for driving the rain brush action.
Owing to having adopted above technical scheme, the invention technological progress is as follows.
The present invention is simple in structure, easy to use.Rainy day, pressure sensor was experienced the weight of rainwater, sends signal to control chip when long-pending rain on glass, control chip is set the work-hours of rain brush, carry out timing by timer, control chip drives the rain brush drive circuit works, and the rain brush driving circuit drives rain brush work.Intelligent wiper has realized that automation ground starts and controls work-hours and drive the rainy day to bring convenience to drivers, and generation avoids traffic accident.
The accompanying drawing explanation
Fig. 1 is control circuit functional block diagram of the present invention.
Wherein: 1. pressure sensor, 2. timer, 3. control chip, 4. rain brush driving circuit, 5. storage battery.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further elaborated.
A kind of functional block diagram of intelligent wiper device control circuit as shown in Figure 1.Be provided with pressure sensor 1, timer 2, control chip 3, rain brush driving circuit 4 and storage battery 5 in control circuit; Wherein storage battery 5 mouths are connected with the input end of timer 2, control chip 3, rain brush driving circuit 4 respectively, and storage battery 5 provides working power for the control circuit normal operation.
Principle of work of the present invention is as follows: when long-pending rain on glass, pressure sensor 1 sends to control chip 3 by the pressure of experiencing rainwater by signal, control chip 3 calculates the interval time of rain brush action according to the information received, send to timer 2 to carry out timing the time calculated; Control chip 3 drives 4 work of rain brush driving circuit simultaneously, and rain brush driving circuit 4 drives rain brush work.
The rainwater of pressure sensor Real-Time Monitoring accumulation on glass, control chip just can ceaselessly be adjusted the interval time of rain brush action, there is no rainwater until on glass, rains while stopping, control chip 3 is no longer to rain brush driving circuit 4 sending action signals, and rain brush just quits work.Thereby the automation that realizes rain brush starts and the action interval time, to drivers to drive the rainy day to bring convenience, and effectively avoids causing because sight line is unclear the generation of traffic accident.
