摘　　要：针对目前交通信号机多采用定时控制或感应控制,难以实现真正意义上的交通参数动态优化,提出一种基于TMS320C6713DSP的自适应智能交通信号机的设计方案;由于选用了高速浮点处理器件,该系统可进行在线动态优化以实现自适应控制;文章详细介绍了系统组成和工作原理,并给出了具体的软硬件设计方案;使用结果表明,这种智能交通信号机系统性能稳定可靠,功能较强,可以方便地实现交通网络协调控制。Aiming at the defects of fixed time and inductive control in the present traffic signal control machine, a new self-adaptive network control machine based on DSP is designed. As selecting a high--speed float processor, the system may optimize the controlling parameter on--line to realize self--adaptive control. This paper discusses the structure and the operating principle of the system in details, and also introduces the software and hardware design. The practical application indicates that the machine possess of reliable performance and powerful functions, and is convenient to achieve the traffic network coordinated control.
