Far infrared light-supplemented system for snapping violated vehicles on road

Abstract

The invention relates to a far infrared light-supplemented system for snapping violated vehicles on the road. The traditional snapping instrument has to use a flash lamp, so the driving is influenced. The far infrared light-supplemented system comprises an optical part and an electronic control part. The optical part comprises a near-infrared light source, a light source drive, a transmitting light collecting lens, a transmitting light shaping device and a receiving light collecting lens; the electronic control part comprises a DSP central processor module, a data acquisition module, a vehicle overspeed detection module, a network transmission module and a power source module. The data acquisition module comprises a CCD (Central Data Display) photoelectric sensor, a video amplifier, a video A/D converter and an FPGA (Field Programmable Gate Array) processor, wherein a target surface of the CDD photoelectric sensor is positioned on a focus of the receiving light collecting lens of the optical part at the front end. By adopting the near-infrared light source as a light source for snapping, the invention solves the technical problem that the flash lamp in the traditional system flashes high light. The invention has the advantages of no high flashing light, no potential safety hazards, full automation and the like as well as compact structure and reasonable layout.

Description

technical field [0001] The invention belongs to the field of electronic information, and relates to an overspeed capture system, in particular to a vehicle overspeed capture system based on near-infrared light source supplementary light. Background technique [0002] In modern society, the development of expressways is very rapid, but the corresponding traffic management equipment is relatively backward. The cause of traffic accidents is usually caused by the speeding of vehicles, so it is very necessary to set up a set of safe and complete speeding capture and camera devices. [0003] Chinese Patent No. 200710303837.3 discloses an overspeed capture system, which can set different speed limit values ​​for different visibility situations; China Invention Patent No. 03103263. The light output time of the flash lamp reaches a certain intensity in an instant, and cooperates with the photosensitive moment of the CCD camera system to obtain higher energy. China Patent No. 200710...
