Abstract

The invention relates to a near-infrared supplementary light system for capturing images of road-violating vehicles. Existing capture instrument must use flashing light, affects driving. The invention includes an optical part and an electronic control part. The optical part includes a near-infrared light source, a light source driver, an emitted light condenser, an emitted light shaping device and a received light condenser; the electronic control part includes a DSP central processor module, a data acquisition module, a vehicle overspeed detection module, a network transmission module and a power supply module. The data acquisition module includes a CCD photoelectric sensor, a video amplifier, a video A / D converter and an FPGA processor. The target surface of the CCD photoelectric sensor is located at the focal point of the receiving light condenser of the front optical part. The invention adopts a near-infrared light source as a light source for snapping, thereby solving the technical problem of flashing strong light in the existing system. The invention has the advantages of no strong flash, no potential safety hazard, complete automation, 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. 20071...
