摘要
针对目前城市交通拥堵往往发生于交叉路口处的现状,采用VHDL语言编程在FPGA上设计了一款行驶车辆智能速度控制系统;该系统通过车载移动终端同十字路口固定终端实时完成信息交换来计算期望速度,其关键逻辑部件在Altera公司的FPGA开发套件QuartusII 9.0上予以实现;经过QuartusII 9.0时序仿真,4000m距离测试,误差为7.1m,达到了预期结果;结果说明该系统运行稳定可靠,得出的期望速度精确度高,文章提出的方案切实可行。
To ease the current urban traffic status that congestion always occurs at the intersection, a traveling vehicle intelligent speed control system is designed with VHDL language based on FPGA. The system complete the exchange of information between the vehicle mo- bile terminal and the crossroads fixed terminal in real time to calculate the desired speed. Its key logic components are realized in Altera corporation＇s FPGA kit QuartusII 9. 0. With timing simulation of QuartusII 9. 0, a test of 4000 meters is carried out, the error is 7.1 me- ters, expected result is achieved. The result shows that the system＇s operation is stable and reliable, and the desired speed on it is high preci- sion, and the proposed scheme is feasible.
