Abstract. With the rapid development of urbanization in China, the problem of traffic congestion is becoming more and more serious. The development of an intelligent traffic signal control system to alleviate traffic congestion is a very valuable research subject. In this paper, the functional requirements of intelligent traffic signal control system are discussed, and the design scheme of intelligent control system of the traffic light is given on the basis of electronic information technology to provide some references for the relevant researchers.

Abstract. With the rapid improvement of the computer control system, the fault-tolerant computer control technology has been applied into many fields. Based on this actual background, the fault-tolerant technology of embedded computer control system is studied in this study, to improve the reliability of present computer system and guarantee the stability of system operation. To find out main system faults, the structure of computer fault-tolerance control system is presented at first, based on which the principal method to achieve the fault tolerance control system is derived. Finally, three principal redundancy methods to achieve the fault tolerance control system are provided, which can be helpful to improving the reliability and stability of the computer system operation
