本设计以MSP430单片机为核心,外接外围电路构成基本电路,使硬件电路能适应所完成的控制功能。在Keil软件中编写C语言程序,最后用Proteus软件进行仿真,基本实现了智能交通控制系统的模拟。该系统可控制红、绿、黄灯按时间依次变换,并有倒读秒功能。在此基础上,通过传感器对车流量的情况进行数据采集。将采集的数据传送给控制中心,进行分析比较。根据比较的结果,将具体的车流量转换成两相位车流量大小的比值。根据比值转换成对红绿灯时间的控制,使交通信号灯时间可根据车流量改变,提高了交叉口的通行效率。

In recent years, with the rapid development of science and technology, a microelectronics technology, computer technology and communication technology as the leading information revolution is booming. Computer technology as one of the three, how to effectively combine with the practical application and play its role. SCM as a branch of computer technology, is constantly applied to the actual life, while driving the traditional control detection update. In real-time detection and automatic control of the application system, the microcontroller is often used as a core component, for the specific application of the characteristics of the object, together with other devices to be improved.
The design of the MSP430 microcontroller as the core, external peripheral circuit constitutes the basic circuit, so that the hardware circuit can be adapted to the completion of the control function. In the Keil software in the preparation of C language program, and finally with Proteus software simulation, the basic realization of the intelligent traffic control system simulation. The system can control the red, green and yellow lights in turn by time, and there are inverted seconds function. On this basis, through the sensor on the traffic situation for data collection. The collected data sent to the control center, for analysis and comparison. According to the comparison result, the specific traffic flow is converted into the ratio of the two-phase vehicle traffic size. According to the ratio of conversion to the traffic light time control, so that the traffic signal time can be changed according to traffic flow, improve the intersection of traffic efficiency.
