基于HCS12 单片机设计一种智能车系统。在该系统中,由红外光电传感器实现路径识别,通过对小车速度的控制,使小车能按照任意给定的黑色引导线平稳地寻迹。实验证明: 系统能很好地满足智能车对路径识别性能和抗干扰能力的要求,速度调节响应时间快,稳态误差小,具有较好的动态性能和良好的鲁棒性。-Based on the HCS12 MCU design an intelligent vehicle system. In this system, the path from the infrared photoelectric sensor to achieve recognition, through the car speed control, so that any given car in accordance with the black guide lines smooth tracing. Results show: The system can be well positioned to meet smart cars on the path to identify the requirements of performance and anti-jamming ability, speed adjustment quick response time, steady-state error is small, has good dynamic performance and good robustness.

交通灯: 1. 因为本设计是交通灯的控制,所以要先了解实际交通灯的变化规律。假设一个十字路口为东西南北走向。初始状态0为东西红灯,南北红灯。然后转状态1南北绿灯通车,东西红灯。过一段时间转状态2,南北绿灯闪几次转亮黄灯,延时几秒,东西仍然红灯。再转状态3,东西绿灯通车,南北红灯。过一段时间转状态4,东西绿灯闪几次转亮黄灯,延时几秒,南北依然红灯。最后循环至状态1。 2. 双色LED是由一个红色LED管芯和一个绿色管芯封装在一起,公用负端。当红色正端加高电平,绿色正端加低电平,红灯亮;红色正端加低电平,绿色正端加高电平,绿灯亮;两端都加高电平,黄灯亮。 急救车和交通灯: 中断服务程序的关键是:1. 保护进入中断时的状态,并在推出中断之前恢复进入时的状态;2. 必须在中断程序中设定是否允许中断重入,即设置EX0位。 本设计使用了INT0中断,一般中断程序进入时应保护 PSW,ACC以及中断程序使用但非其专用的寄存器。本设计中的INT0程序保护了PSW,ACC,2等三个寄存器并且在退出前恢复了这三个寄存器。另外中断程序中涉及到关键数据的设置时应关中断,及设置时不允许重入。本设计中没有涉及这种情况。 name:trled1.asm trled2.asm-traffic lights : 1. Because of the design of the traffic lights, so there must first understand the traffic lights change. Assuming a crossroads for the east-west north-south. Initial state of things 0 red light, red light north-south. Then the state opening of a north-south green, red things. For a period of time to state 2-green flashing yellow light switch several times, a few seconds delay, things are still red. Three sub-state, opening things green, red ligh
