Abstract


In order to reduce the risk of traffic accidents caused by low visibility on highways, this study proposes a new type of energy-saving projection protruding signs based on the principle of hydraulic power generation and block section. The protruding signs utilize a hydraulic power generator comprised of a liquid pressure capsule, flow-regulating device, permanent-magnet generator, and so on, which can collect the pressure exerted by cars on the ground and convert it into electrical energy. The converted electric energy is calculated using a mathematical model, and a simulation model of hydraulic power generation is established using Matlab/Simulink. The protruding signs of this new lighting control system were designed based on the principle of block section theory, sensor technology, microcontroller technology, and Altium Designer software and other related tools. This system may dynamically and intelligently control the working condition of protruding signs and luminous colors on the road at different sections in accordance with real-time traffic conditions, which may help drivers understand road alignment conditions and the motion states of cars ahead clearly.
