急救车与交通灯）（1）南北与东西方向，每个方面由红黄绿三个灯控制（2）南北向：　红（30秒），黄（5秒），绿（25秒）　　　东西向： 红（35秒），黄（5秒），绿（25秒）　　　上述基本参数可以根据实际情况自行调整，灯的变化规律与实际路口规律相同，绿灯在最后5秒钟时，黄灯亮，然后红灯亮，不允许两个方面同时亮绿灯。（3）绿灯的时间显示在数码管上进行显示。（4）可以通过一个开关控制，当开关信号为0时，整个交通灯全灭提高要求：（1）设计一个紧急控制开关信号，当紧急开关信号为1时，两个方向的灯全为红灯。紧急开关撤消后，按照开关按下之前的状态继续运行（其参数要保存）。（2）设计一个夜间行车开关，当开关按下后，两个方向都只有黄灯闪烁，其它灯熄灭。（3）设计两个方向的亮时时间可调。-emergency vehicles and traffic lights) (1) North and South and east-west direction, each with three yellow-green from red lights control (2) to the north and south : red (30 seconds), yellow (5 seconds), Green (25 seconds) to things : red (35 seconds), yellow (5 seconds) Green (25 seconds) above basic parameters can be adjusted to the actual situation, the light changes with the actual law of the same intersection, the green light in the final five seconds, the yellow light is on, and then a red light, bright, not two fronts simultaneously bright green. (3) the green light at the time displayed on the digital display control. (4) can be controlled by a

具体的硬件结构,大家可以看 WS 系列产品的原理图 * 利用AT89S51单片机来制作一个手动计数器，在AT89S51单片机的P3.3管脚接一个轻触开关， * 作为手动计数的按钮. 数码管驱动采用动态扫描方式用单片机的P0.0－P0.7驱动数码管的段码， * P1.3 控制个位数码管的共阳极公共端，P1.2 控制十位数码管的共阳极公共端 * 通过按一下P3.3按键,数码管做 1 的累加, 实现00~99的计数功能,当计到99时又从00开始. * 大家可自行修改程序,扩展到0000~9999的计数范围-Specific hardware architecture, we can look WS schematic family of products using AT89S51* Single-chip to produce a manual counter, in the P3.3 pin MCU AT89S51 by one touch switch,* as a manual count of button. nixie tube driven by dynamic scanning with MCU P0.0-P0.7 driver code segment digital tube,* P1.3 control bit digital tube anode of a total public client, P1.2 control of 10 digital total anode tube through public client* P3.3 click buttons, a digital pipe to do one of the cumulative, realize 00 ~ 99 count function, when the total to 99 from 00 the beginning of time.* everyone can modify the program, extended to 0000 range of ~ 9999 count
