1.东西方向、南北方向均有红、黄、绿三种信号灯； 2.东西干道和南北干道，绿灯下情况通行，红灯情况下不行，黄灯情况下 慢行； 3.东西干道和南北干道交替控制； 4.实时提醒绿灯亮的剩余时间； 5.通行时间可调； 6.雾霾或夜间模式按钮按下，所有方向显示黄灯.(1. there are three red, yellow and green lights in east-west direction and north-south direction. 2. the East West trunk road and the north-south trunk road pass under the green light. 3. East and west main road and the north and South Main Road alternately control; 4. reminding the remaining time of the green light in real time; 5. the time can be adjusted; 6. haze or night mode button is pressed, all directions show yellow light.)

线路通断检测器的设计： 1．用压电陶瓷蜂鸣片作为电声元件。 2．用两根导线作为测试探针 3．线路通断是通过测试电阻的大小来判断，有以下三种情况： （1）若150Ω<Rx<900Ω，则蜂鸣片不发出声响。 （2）若Rx>900Ω或者Rx<150Ω，则蜂鸣片发出间歇式的滴－滴声响。 以上各临界阻值（150Ω和900Ω），允许误差±10％ 4．＋15V直流稳压电源需要设计。 (Line-off detector design: 1. Piezoelectric ceramic buzzer as the electro-acoustic components. 2. As a test probe with two wires 3. Lines off by testing the resistance to determine the size, the following three conditions: (1) If 150Ω <Rx <900Ω, the buzzer is not audible. (2) If Rx> 900Ω or Rx <150Ω, then the buzzer sent intermittent drip- drip sound. Above the critical resistance (150Ω and 900Ω), tolerance ± 10 4.+15 V DC power supply need to design. )

在Proteus环境下使用LM311电压比较器进行比较和整流。LM311电压比较器设计运行在更宽的电源电压，从标准的±15V运算放大器到单5V电源用于逻辑集成电路。 (LM311 compare shaping, using Proteus LM311 voltage comparator designed to operate over a wider supply voltage: 15V op amps from a standard to a single 5V power supply for the logic IC)
