prepared for the first national intelligent vehicle contest. The vehicle system, with
the Freescale16-bit single-chip MC9S12DG128 as its control microprocessor, uses
image-sensor module based on camera to obtain lane image information, then
abstract the black line on the contest lane by edge-detection method and calculate
the position difference between the vehicle and the black line with which we will
have a PID feedback control on the steering angle. The vehicle also uses a
speed-sensor made by ourselves to obtain the real time speed which will be used in a
speed feedback that adopts Bang-Bang control method. Certain algorithm will be
employed to analyze the lane styles in front of the vehicle and set different vehicle
speed according to the lane style. The mechanical structure and adjustment method
of the vehicle, the design, parameters, and relative tests of the vehicle steer module

Description: 我所做的单片机串行通信发射机主要在实验室完成,参考有关的书籍和资料,个人完成电路的设计、焊接、检查、调试,再根据自己的硬件和通信协议用汇编语言编写发射和显示程序,然后加电调试,最终达到准确无误的发射和显示。在这过程中需要选择适当的元件,合理的电路图扎实的焊接技术,基本的故障排除和纠正能力,会使用基本的仪器对硬件进行调试,会熟练的运用汇编语言编写程序,会用相关的软件对自己的程序进行翻译,并烧进芯片中,要与对方接收机统一通信协议,要耐心的反复检查、修改和调试,直到达到预期目的。-Abstract:
With the rapid development of science and technology in recent years, the application of SCM is the deepening of the same time promote the traditional control detection technologies are increasingly updated. In real-time detection and automatic control of microcomputer application system, the microcontroller is often used as a core component to use only SCM knowledge is not enough, but also according to the specific hardware architecture hardware and software, to be improved.
Crossroads shuttle vehicles, pedestrians bustling Dealers lane, walkways, and orderly. Rely on to achieve this orderly order? Rely on automatic command system of traffic lights.

Description: 以单片机为核心,设计一个简单交通灯控制系统,设A车道与B车道交叉组成十字路口,A是主道,B是支道。设计要求如下:
(1) 用发光二极管模拟交通信号灯、两个方向分别设置红、绿、黄3种通行指示灯,用按键开关模拟车辆检测信号。
(2) 正常情况下,A、B两车道轮流放行, A车道放行40秒,其中5秒用于警告,B车道放行25秒,其中5秒用于警告。有计时牌显示路口通行转换剩余时间。
(3) 在交通繁忙时,交通信号灯控制系统应有手控开关,可人为地改变信号灯的状态,以缓解交通拥挤状况。在B车道放行期间,若A车道有车而B车道无车,按下开关K1使A车道放行15秒;在A车道放行期间,若B车道有车而A车道无车,按下开关K2使B车道放行15秒。
(4) 有特种车辆如119、120通过路口时,系统可转为特种车辆放行,其他车辆禁止通行的状态,15s后系统恢复正常管理。
(5) 两个方向放行的时间可以通过键盘设置。
