Paper Abstract

Road speed control humps have the effect of strengthening transportation safety by preventing traffic accidents. However, vehicles will produce strong mechanical vibrations when crossing speed control humps at high speed. These vibrations affect the passenger's comfort and cause machine parts damage. Early warning systems in vehicles for road speed control humps were designed based on DSP and CCD sensors. The system uses a CCD camera to take the picture of the road speed control humps. The image information is processed and recognised by DSP. Then the related voice and image information is given quickly and accurately after the system processes. This information will remind the driver to prepare for slowing down in good time, it makes them safe and comfortable to pass over the road speed control hump.TMS320DM642DSP early warning system in vehicles was illustrated from three aspects of the image collection module, the image discernment module and the early warning export module. TMS320C6x soft develop flow was introduced in this paper. The system has strong practicality, rapid response and well directed-viewing.
