武汉科技大学微机原理课程设计-模拟电梯系统(汇编)二○一三～二○一四学年第二学期电子技术学院电子信息工程系课程设计报告书班级：姓名：课程名称：微机原理及应用课程设计学时学分：1周1学分指导老师：杨君二○一三年十二月三十一日一、课程设计目的：综合运用本课程知识，利用集成电路设计实现一些中小规模电子电路或者完成一定功能的程序，以复习巩固课堂所学的理论知识，提高程序设计实现系统、绘制系统电路图的能力，为实际应用奠定一定的基础。二、课程设计时间安排：第一天：教师布置设计任务，讲解设计要求，提示设计要点。第二～三天：查阅资料（在图书馆或上网），提出设计方案。第三～七天：画出详细设计图（电路图），编写程序，调试程序，得出实验结果并写出设计报告。三、课程设计选题：设计要求:(1).在1--8楼之间一次可输入多个任意楼层号连续控制电梯按指定楼层号顺序上升与下降.以上过程完成后可重新输入任意楼层号连续控制电梯按指定楼层号顺序上升与下降.只有按ESC键才退出程序返回DOS状态。例如:1-3-5-7-6-4-2-1(可观察教十楼电梯的实际运行情况).(2).在1--7楼之间按任意顺序不连续控制电梯上升与下降.按一次计算机键盘的上箭头电梯上升一楼,按一次计算机键盘的下箭头电梯下降一楼.(上箭头的ASCII码19H,下箭头的ASCII码1AH.)(3).在电梯上升与下降过程中,要显示出1--7楼之间所要到达的楼层数,同时还要用箭头显示电梯是上升状态还是下降状态.(4).电梯运行到指定楼层后,打开电梯门，然后关门继续运行.(5).电梯运行时,在任意时刻遇到紧急情况时应能实时中断电梯运行.也可以AH=6屏幕初始化或上卷.AL=0整个窗口空白.INT10H;CH=左上角行号,CL=左下角列号.ENDM;DH=右上角行号,DL=右下角列号.;---------------------------------------POSMACRO;移动光标的宏MOVBH,00H;BH=页号DH,DL=行号,列号.MOVAH,02H;AH=2置光标位置.INT10HENDM;---------------------------------------HENGMACROX1,Y1,COLOR,X2;写横的宏LOCALBH1;定义标号MOVCX,X1;起始点横作标-->CXMOVDX,Y1;起始点纵作标-->DXBH1:MOVAH,0CH;写象素MOVAL,COLOR;设定颜色参数-->ALINT10HINCCXCMPCX,X2;写至终点横作标为止JNZBH1ENDM;---------------------------------------SHUMACROCX1,CY1,COLOR,CY2;写竖的宏LOCALBH2;定义标号MOVCX,CX1MOVDX,CY1BH2:MOVAH,0CHMOVAL,COLOR;AL=(00--0FH)共16种颜色.INT10HINCDXCMPDX,CY2JNZBH2ENDM;---------------------------------------DELAYMACRO;延时1s的宏LOCALREADPUSHDX;入栈，保护原有DX、CX中的数据PUSHCXSUBAX,AXINT1AH;INT1AH的0号功能读当前时钟值，CX:DX=时钟计数值MOVTIME,DXMOVTIME[2],CXREAD:SUBAX,AXINT1AHSUBDX,TIMESBBCX,TIME[2]CMPDX,DLYJBREADPOPCX;出栈，恢复现场POPDXENDM;---------------------------------------UPMACRON,DX1;小方块上升的宏LOCALUPA,UPB;定义标号MOVAL,N;小方块从N-1层上升至N层MOVCH,30;小方块上升一层，并且将下一层的小方块清除MULCH;30*N个像素MOVDX,430SUBDX,AX;430-30*N个像素得到画小方块的纵坐标下限值MOV[DZ],DXADDDX,20;每个小方块边长为20个像素MOVDX1,DX;得到纵坐标上限值UPA:HENG170,[DZ],0CH,190;画小方块INC[DZ]MOVAX,DX1CMP[DZ],AXJNZUPAADDDX,11;坐标调整到移动之前的坐标MOV[DZ],DXADDDX,20MOVDX1,DXUPB:HENG170,[DZ],00H,190;擦原小方块INC[DZ]MOVAX,DX1CMP[DZ],AXJNZUPBENDM;---------------------------------------DOWNMACRON,DX1;小方块下降的宏LOCALDOWNA,DOWNB;定义标号MOVAL,N;小方块从N+1层下降至N层MOVCH,30;小方块下降一层，并且将上一层的小方块清除MULCHMOVDX,430SUBDX,AXMOV[DZ],DXADDDX,20MOVDX1,DXDOWNA:HENG170,[DZ],0CH,190;画小方块INC[DZ]MOVAX,DX1CMP[DZ],AXJNZDOWNASUBDX,49MOV[DZ],DXADDDX,20MOVDX1,DXDOWNB:HENG170,[DZ],00H,190;擦原有小方块INC[DZ]MOVAX,DX1CMP[DZ],AXJNZDOWNBENDM;---------------------------------------CLOSEMACRO;画电梯关门状态的宏LOCALCEMOV[DZ],220CE:HENG210,[DZ],09H,370;电梯关门INC[DZ]CMP[DZ],420JNZCESHU291,220,02H,420;电梯大门缝隙SHU290,220,02H,420SHU289,220,02H,420ENDM;---------------------------------------HALFMACRO;画电梯半开门状态的宏LOCALHFMOV[DZ],221HF:HENG210,[DZ],09H,250;电梯半开门HENG252,[DZ],07H,328HENG330,[DZ],09H,370INC[DZ]CMP[DZ],420JNZHFSHU251,220,02H,420;电梯大门缝隙SHU329,220,02H,420ENDM;---------------------------------------FULLMACRO;画电梯全开门状态的宏LOCALFLMOV[DZ],221FL:HENG210,[DZ],09H,215;电梯全开门HENG217,[DZ],07H,363HENG365,[DZ],09H,370INC[DZ]CMP[DZ],420JNZFLSHU216,220,02H,420;电梯大门缝隙SHU364,220,02H,420ENDM;---------------------------------------PAUSEMACRO;电梯紧急暂停的宏LOCALWAIT,WANSUBAX,AXMOVAH,1INT16HCMPAL,'a';读取键盘缓存中是否有"a"，有就进入暂停等待循环，没有则退出JNZWANMOVDX,0301HPOSMOVDX,OFFSETMSG7;显示MSG7MOVAH,9INT21HMOVAH,0CH;清空键盘缓存INT21HWAIT:CLC;CF=0MOVAH,1INT16HCMPAL,'b';检测键盘缓存中是否有"b"，有就退出暂停等待循环，没有则继续循环JNZWAITWAN:MOVDX,0301HPOSMOVDX,OFFSETMSG6;用于将MSG7的信息擦除MOVAH,9INT21HMOVAH,0CHINT21HENDM;---------------------------------------datasegmentMSG1DB'Pleasepress"1-8"or"w/s"rootherstoterminate.(eg:1-3-8/w):$';输出多个空格是为了清空上一次的输入MSG2DB'Pleasepressanykey.','$'MSG3DB'Floor:$'MSG4DB'Direction:$'MSG5DB'To:$'MSG6DB'Whentheelevatorrunning,pleasepress"a"toemergencystop.$'MSG7DB'Pleasepress"b"tocontinue.$'MSG8DB'WUSTLiGang2014.2.5$'DATDB0FFH,0,255DUP(0)DLYEQU18DZDW0TIMEDW0,0NUM1DB1NUM2DB1COUNTDB0DX1DW0DX2DW0dataends;---------------------------------------stackssegmentSTADW100DUP(0)TOPDW?stacksends;---------------------------------------codesegmentassumecs:code,ds:data,ss:stacks;---------------------------------------startprocfarmovax,datamovds,axmovax,stacksmovss,axmovax,datamoves,axpushaxpushbxpushcxpushdxpushsipushdiMOVCX,0MOVDX,2479HMOVBH,7MOVAX,0601HINT10HMOVAX,0012H;置图形显示方式INT10H;640列*480行,16色.MOVDX,0;光标位置初始化POSHENG220,99,0AH,420;信息栏外边框HENG220,151,0AH,420SHU220,99,0AH,151SHU420,99,0AH,151HENG223,102,0AH,417;信息栏内边框HENG223,148,0AH,417SHU223,102,0AH,148SHU417,102,0AH,148CLOSE;电梯大门处于关闭状态HENG210,220,02H,370;电梯大门缝隙边框HENG210,420,02H,370SHU210,220,02H,420SHU370,220,02H,420HENG209,219,02H,371;加粗边框SHU209,220,02H,420SHU371,220,02H,420MOV[DZ],219MOVDX1,210MOVDX2,370SB1:HENGDX1,[DZ],03H,DX2;三维电梯上侧面DEC[DZ]INCDX1INCDX2CMP[DZ],180JNZSB1MOV[DZ],371MOVDX1,220MOVDX2,420SB2:SHU[DZ],DX1,03H,DX2;三维电梯右侧面INC[DZ]DECDX1DECDX2CMP[DZ],410JNZSB2MOV[DZ],421SB3:HENG160,[DZ],0EH,200;画电梯框架SUB[DZ],30CMP[DZ],151JNZSB3SHU160,181,0EH,422SHU200,181,0EH,422MOV[DZ],400BRICK:HENG170,[DZ],0CH,190;画初始小方块INC[DZ]MOVAX,420CMP[DZ],AXJNZBRICKMOVDX,072BHPOSMOVDL,NUM1ADDDL,30HMOVAH,2INT21H;初始楼层显示"1"MOVDX,1C3BHPOSMOVDX,OFFSETMSG8;显示MSG8MOVAH,9INT21HMOVDX,0723HPOSMOVDX,OFFSETMSG3;显示MSG3MOVAH,9INT21HMOVDX,081DHPOSMOVDX,OFFSETMSG4;显示MSG4MOVAH,9INT21HMOVDX,082DHPOSMOVDX,OFF
