Description: 自动交通管理系统 用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁止线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示） 同时用2位数码管进行30秒钟递减时间显示。-automatic traffic management system using red, green, yellow a total of three light-emitting diodes, said two traffic lights, using SCM time simulation shows the regular traffic signal control. Signal changes in the law to be as follows : 1) Release Line : green clearance 25 seconds, bright yellow warning five seconds, and then the red-ban. 2) prohibit the lines : red-Ban 30 seconds, then green clearance. 3) When the red light in one direction- that if the direction of a car passed, the use of loudspeakers sound alarm. (Red light signals can hit 3- 5V analog said), while using two digital tube for 30 seconds decreasing time displayed. Platform: |

声光型数字温度报警器是基于单片机控制的数字化功能平台。以单片机为核心控制的电路，结合数码管及其它元器件的使用，温度传感器接收温度，通过电路，使它能在数码管上显示。
2、温度报警
通过C语言编写的程序来控制单片机的运行，设置上限温度，当温度达到所设定的温度时，蜂鸣器就接通，发出声音，提示温度超过所设定。
3．报警解除
当实际温度超过所设定的温度时，蜂鸣器报警，如果要切断报警，可以做出终止报警，但是温度还在数码管上显示。
-1, temperature display
The sound and light type digital temperature alarm is a digital function platform based on single chip microcomputer control. With single chip microcomputer as the core control circuit, combined with the use of digital control and other components, temperature sensor to receive temperature, through the circuit, so that it can display on the digital tube.
2, temperature alarm
Through the C language program to control the operation of the microcontroller, set the upper limit temperature, when the temperature reaches the set temperature, the buzzer will switch on, sound, prompt temperature exceeds the set.
3 alarm release
When the actual temperature exceeds the set temperature, the buzzer alarm, if you want to cut off the alarm, you can make the termination of the alarm, but the temperature is still displayed on the digital tube. Platform: |
