Automatic starting system and method for automobile windshield wiper
2016
The invention relates to an automatic starting system for an automobile windshield wiper. A camera is connected with a control module to acquire information of raindrops on the outer side of a front windshield and send the information to an image processing system. The image processing system is connected with a humidity sensor to trigger the humidity sensor. The humidity sensor is connected with the input end of an operational amplifier to acquire humidity signals and send the humidity signals to the operational amplifier to be processed. The output end of the operational amplifier is connected with a single-chip microcomputer, and the processed humidity signals are sent to the single-chip microcomputer to be controlled. The single-chip microcomputer is connected with the windshield wiper to control the windshield wiper. The raindrops on the automobile front windshield and the transparency of the windshield are detected through the visual processing technology, the information of rainwater outside an automobile can be accurately judged, errors of a visual system are effectively corrected, and therefore the windshield wiper is more accurately controlled, a visual processing system and a humidity sensor detection system jointly act to judge whether the automobile windshield wiper is started or not, and the windshield wiper is more accurately controlled.
