vb写一个简单红绿灯程序代码,希望能注释和思路写清楚一点,我菜鸟!谢谢

'ZT是当前状态记录,Qzt是前状态记录,SJ是时间记录

红绿灯的plc简单编程是什么?

PLC的编程不同于电脑中软件编程,它需要对具体的输入/输出端口信号进行处理和操作(或者说对一个字节的每一个 bit 进行处理和操作)。

南北方向:

南北绿(8s),东西红(8s)

南北黄(2.1s),东西红(2.1s)

南北红(10.1s),东西绿(8s),东西黄(2.1s)

东西方向:

东西红(10.1s),南北绿(8s),南北黄(2.1s)

东西绿(8s),南北红(8s)

东西黄(2.1s),南北红(2.1s)

中央处理单元

中央处理器(CPU)是PLC的控制中枢,也是PLC的核心部件,其性能决定了PLC的性能。中央处理器由控制器、运算器和寄存器组成,这些电路都集中在一块芯片上,通过地址总线、控制总线与存储器的输入/输出接口电路相连。中央处理器的作用是处理和运行用户程序,进行逻辑和数学运算,控制整个系统使之协调。

用VB编写“红绿灯”程序

Dim s As Integer

Dim n As Integer

'单击“红灯”按钮

Private Sub Command1_Click()

Shape6.Visible = True : Shape7.Visible = False : Shape8.Visible = False

End Sub

'单击“黄灯”按钮

Private Sub Command2_Click()

Shape6.Visible = False : Shape7.Visible = True : Shape8.Visible = False

End Sub

'单击“绿灯”按钮

Private Sub Command3_Click()

Shape6.Visible = False : Shape7.Visible = False : Shape8.Visible = True

End Sub

'单击“自动”按钮

Private Sub Command4_Click()

Timer1.Enabled = True

Command1.Enabled = False

Command2.Enabled = False

Command3.Enabled = False

n = 0 : s = 0

End Sub

'单击“手动”按钮

Private Sub Command5_Click()

Timer1.Enabled = False

Label1.Caption = ""

Shape6.Visible = False

Shape7.Visible = False

Shape8.Visible = False

Command1.Enabled = True

Command2.Enabled = True

Command3.Enabled = True

End Sub

'时钟控件启动

Private Sub Timer1_Timer()

Select Case n

Case 0

Shape6.Visible = True

Shape7.Visible = False

Shape8.Visible = False

Label1.Caption = 3 - s

s = s + 1

If s 3 Then

n = 1

s = 0

End If

Case 1

Shape6.Visible = False

Shape7.Visible = True

Shape8.Visible = False

n = 2

Case 2

Shape6.Visible = False

Shape7.Visible = False

Shape8.Visible = True

Label1.Caption = 3 - s

s = s + 1

If s 3 Then

n = 0 : s = 0

End If

JS中制作红绿灯的代码?

只能修改页面统一代码中的颜色设置: a:hover { color: #FFFFFF; text-decoration: none; } a:visited { color: #fff; text-decoration: none; }

关于单片机简单的红绿灯程序问题

代码修改如下,经keil编译,proteus仿真结果为 P1.0亮10秒,然后P1.1亮2秒,然后P1.2亮10秒,最后P1.0亮10秒,,,

#include?reg51.h

sbit?R=P1^0;//HONG

sbit?W=P1^1;//HUANG

sbit?L=P1^2;//LV

unsigned?int?a,b=0;

//unsigned?char?code?c[]={0xfe,0xfc,0xfb};//1110,1100,1011

unsigned?char?code?c[]={0xfe,0xfD,0xfb,0xfd};//1110,1101,1011,1101//红?黄?绿?黄//修正黄灯的值,增加一个状态

void?timer10s?()?interrupt?1

{

?if?(a2000)

????{

????????TH0=0xec;//5ms

????????TL0=0x78;

????????a++;

??//??????b=0;//这里不能对b赋值

????????TR0=1;

????????TR1=0;//【增加】

????}

????if?(a=2000)

????{

????????TH0=0xec;

????????TL0=0x78;

????????a=0;

????????b++;//b=1;

????????if(b==4)?b=0;//【增加】

????????TR1=1;

????????TR0=0;//【增加】

????}

}

void?timer2s?()interrupt?3

{

???

???if?(a400)

????{

????????TH1=0xec;

????????TL1=0x78;

????????a++;

????????TR1=1;

????????TR0=0;

????}

????if?(a=400)

????{

????????TH1=0xec;

????????TL1=0x78;

????????a=0;

????????b++;//b=2;

????????//

????????if(b==4)?b=0;//【增加】

????????TR0=1;

????????TR1=0;//【增加】

????}

}

void?main?()

{

????EA=1;

????ET0=1;

????ET1=1;

????TMOD=0X11;

????TH0=0xec;//5MS

????TL0=0x78;

????TH1=0xec;

????TL1=0x78;

????TR0=1;

????TR1=0;

????P1=c[0];

????b=0;////【增加】

????while?(1)

????{

????????switch?(b)

????????{

????????????case?0x00:P1=c[0];break;

????????????case?0x01:P1=c[1];break;

????????????case?0x02:P1=c[2];break;

????????????case?0x03:P1=c[3];break;//增加一个状态

????????}

????}

}

以上代码可以优化,如下:

#include?reg51.h

sbit?R=P1^0;//HONG

sbit?W=P1^1;//HUANG

sbit?L=P1^2;//LV

unsigned?int?a,b=0;

unsigned?char?code?c[]={0xfe,0xfD,0xfb,0xfd};

void?timer10s?()?interrupt?1

{

????TH0=0xec;//5ms

????TL0=0x78;

????a++;

????if(TR1==1)?TR1=0;

????if?(a=2000)

????{

????????a=0;

????????b++;

????????if(b==4)?b=0;

????????TR1=1;

????????TR0=0;

????}

}

void?timer2s?()interrupt?3

{

????TH1=0xec;

????TL1=0x78;

????a++;?

????if(TR0==1)?TR0=0;

????if?(a=400)

????{

????????a=0;

????????b++;

????????if(b==4)?b=0;

????????TR0=1;

????????TR1=0;

????}

}

void?main?()

{

????EA=1;

????ET0=1;

????ET1=1;

????TMOD=0X11;

????TH0=0xec;//5MS

????TL0=0x78;

????TH1=0xec;

????TL1=0x78;

????TR0=1;

????TR1=0;

????a=0;//

????b=0;//

????while?(1)

????{

????????switch?(b)

????????{

????????????case?0x00:P1=c[0];break;

????????????case?0x01:P1=c[1];break;

????????????case?0x02:P1=c[2];break;

????????????case?0x03:P1=c[3];break;

????????}

????}
