Photoelectric sensing formula high -speed inlet gets to clamp and puts

The utility model discloses a photoelectric sensing formula high -speed inlet gets to clamp and puts, including go out to clamp put, photic ware, light projector and control box, its basic principle be utilize the light projector with light by lens with its focus and project the lens of photic ware, transmit again to the photo resistance, the photo resistance is transformed into the signal of telecommunication with the light signal of receiving, the control action of various differences can further be made to this signal of telecommunication. After the automobile sailed high -speed crossing into, the light between light projector and the photic ware was covered by the automobile body, and consequently photosensitive resistance detection changes the control action that the hairpin was made to the signal of telecommunication into to light signal's interrupt, after the automobile sailed out of high -speed crossing, the photo resistance obtained the new signal of telecommunication again and regains the card feed
