Description
Technical field
The present invention relates to Automobile Products, particularly relate to a kind of intelligent windscreen wiper automatic control system.
Background technology
Rain brush is a kind of instrument simply cleared up to prevent rainwater and other pollutant effect sight lines on motor vehicles Herba Plantaginis glass.
Traditional batch (-type) rain brush, rain brush speed can divide three to level Four to carry out being manually adjusted by driver according to the sight line that rainfall impact is driven.Although present automobile becomes the most easily to drive, reliably.But drive the automobile of tradition rain brush, advancing in the rain when, also to divert one's attention to adjust rain brush, disperse the attention of motorist undoubtedly, traffic safety is made a strong impact.
Although some intelligent wiper can realize automatic control function, but the trouble of installation, in addition it is also necessary to automobile circuit is adjusted, allow some it is intended that car owner hang back.Some intelligent rain brush controller domestic, the most real intellectuality, they are only with speed hook, and the fast rain brush of car is fast, and the slow rain brush of car is slow, and car stops rain brush and stops.This windshield-wiper controller does not the most realize intellectuality, and only a kind of transitional product, can not reflect rainy truth, it is impossible to realize automatic speed regulating function.
Utility model content
The present invention proposes the windshield wiper control system that one is controlled automatically, response speed is fast and control is accurate, safe and intelligent.
The technical scheme is that and be achieved in that:
A kind of intelligent wiper control system, including: capacitance electrode, detection chip, power supply and single-chip microcomputer；Capacitance electrode is electrically connected with detection chip, and power supply provides electricity for rain brush automatic control system；Detection chip is electrically connected with single-chip microcomputer；Detection chip is connected by I2C bus with single-chip microcomputer；Capacitance electrode is provided with multiple test point；Rainwater is got on capacitance electrode, the capacitance change of detection chip detection capacitance electrode, the signal of detection is sent to single-chip microcomputer by data/address bus, the classification chart that the signal of the detection that single-chip microcomputer receives is corresponding with the changing value of electric capacity with the amount of rainfall preset judges, thus judge the size of amount of rainfall, then the frequency moved after controlling the unlatching of rain brush, and startup.
The intelligent wiper control system that the present invention provides, when rainwater reaches on capacitance electrode, electric capacity can change, and judges whether the size of rainfall and rainfall, the frequency being started by Single-chip Controlling rain brush and being started the most again by detecting its change.Being judged by capacitance detecting principle, it is judged that the most accurate, detected by data/address bus, the detection time is short.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the circuit block diagram of the present invention a kind of intelligent wiper control system.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
A kind of intelligent wiper control system, including: capacitance electrode 1, detection chip 2, power supply 3 and single-chip microcomputer 4；Capacitance electrode 1 is electrically connected with detection chip 2, and power supply 3 provides electricity for rain brush automatic control system；Detection chip 2 is electrically connected with single-chip microcomputer 4.
Preferably, described detection chip 2 is electrically connected with by serial ports (I2C) with described single-chip microcomputer 4, and it follows I2C bus protocol.
Preferably, described capacitance electrode 1 is provided with multiple test point.
Preferably, described detection chip 2 is electrically connected with by data/address bus with described single-chip microcomputer 4, and data/address bus uses I2C bus.
Preferably, described power supply 3 is automobile storage battery.
Preferably, described detection chip 2 is sensor.
Preferably, also include that rain brush drive control module 5, described rain brush drive control module 5 are electrically connected with described single-chip microcomputer 4.
Preferably, the intelligent wiper control system that the present invention provides, when rainwater is got on capacitance electrode, the capacitance of capacitor will change, and capacitance electrode adnexa is provided with multiple test point, therefore detection chip detection capacitance variations, and it is the most accurate in order to detect, therefore detection chip can also arrange multiple, the signal of detection chip detection sends single-chip microcomputer to by data/address bus, classification chart corresponding with the changing value of electric capacity with the amount of rainfall preset for the value of detection then can be judged by single-chip microcomputer, thus judge the size of amount of rainfall, it is light rain or moderate rain or heavy rain or extra torrential rain etc., control rain brush the most again to control to drive module to control whether rain brush is opened, and the frequency of motion after opening, realize intelligence to control automatically, and precisely the most quickly react.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
