| Abstract: | Self recognition instrument of road surface condition distinguishes the differences between reflectance and scattering coefficient among all kinds of road surface conditions and identifies them. In this paper, the detailed design of its photo-electric detection circuit, which realized the detection of diffuse and reflection signals in the complicated circumstances on the road, is introduced based on the principle of photo-electric detection. It has characteristics of steady performance, reliable operation, high accuracy and the like. |
