ABSTRACT
This design take the monolithic integrated circuit as a core, uses main from the double MCU structure, takes the direct acting by the bi-color LED photo tube arrow and about the corner instructed, instructed by the LED nixietube as the countdown, takes the pedestrian general instruction by the bi-color LED lattice, realizes the special purpose vehicle examination by the digital coding wireless mode of transmission, has completed topic request all functions. Based on this, we additionally built the high resolution (320×240) large screen LCD real time display system each condition, simultaneously show date and time; Additionally built the pedestrian to pass through also matches by the image animation and the warm voice prompt; Additionally built has been possible to establish the branch separately according to the traffic congestion situation and the inferior yang or male principle general time, and carried on the optimization design to the system mechanism, the integrity has been good, user-friendly was strong, the reliability was high.
Key words: Double MCU Wireless transmission Bi-color LED lattice Optimization design
