Design of intelligent traffic signal controller

Aiming the deficiency of control performance of existing traffic signal controller, we finish whole design of intelligent traffic signal controller based on MPC8245 processor and Hard Hat Linux kernel. After designing minimum system of MPC8245, we extend Compact PCI bus so as to finish video capture, network communication, and serial communication utilizing all kinds of PCI card. In our systems we finish the functions of signal acquisition and control by a multi-serial port card based on Compact PCI bus, so we expound the design theory of multi-serial card, and the design method of drivers. In addition, we tailor Linux kernel and file system, and make system satisfy the application requirements of traffic signal control. As a result, traffic signal controller has strong intelligent control performance, and makes the implementation of intelligent traffic possible.
