8031工业顺序控制程序

第第页8031工业顺序控制程序8031工业顺序控制程序在工业控制中，象冲压、注塑、轻纺、制瓶等生产过程，都是一些继续生产过程，按某种顺序有规律的完成预定的动作，对这类继续生产过程的控制称顺序控制，象注塑机工艺过程大致按“合模注射延时开模产伸产退”顺序动作，用单片机最易实现。8031的P1.0~P1.6控制注塑机的七道工序，现模拟控制七只发光二极管的点亮，低电平有效，设定每道工序时间转换为延时，P3.4为开工启动开关，高电平动作。P3.3为外部故障输入模拟开关，低电平报警，P1.7为报警声音输出，设定6道工序只有一位输出，第七道工序三位有输出。程序框图程序ORG0190H019075907FPO10:MOVP1,#7FH019343B000ORLP3,#00H019630B4FDPO11:JNBP3.4,PO11;开工吗？019943A884ORLIE,#84H019C43B801ORLIP,#01H019F75D000MOVPSW,#00H;初始化01A2758153MOVSP,#53H01A575907EPO12:MOVP1,#7EH;第一道工序01A831F1ACALLPO1B01AA75907DMOVP1,#7DH;第二道工序01AD31F1ACALLPO1B01AF75907BMOVP1,#7BH;第三道工序01B231F1ACALLPO1B01B4759077MOVP1,#77H;第四道工序01B731F1ACALLPO1B01B975906FMOVP1,#6FH;第五道工序01BC31F1ACALLPO1B01BE75905FMOVP1,#5FH;第六道工序01C131F1ACALLPO1B01C375900FMOVP1,#0FH;第七道工序01C631A5ACALLPO1201C880DBSJMPPO1201CA8AF0PO16:MOVB,R2;保护现场01CC75907FPO17:MOVP1,#7FH;关输出01CF7520A0MOV20H,#0A0H;振荡次数01D2D297PO18:SETBP1.7;振荡01D431ECACALLPO1A;延时01D6C297CLRP1.7;停振01D831ECACALLPO1A;延时01DAD520F5DJNZ20H,PO18;不为0转01DDC297CLRP1.701DF31ECACALLPO1A;停振01E130B3E8JNBP3.3,PO17;故障消除吗？01E4AAF0MOVR2,B;恢复现场01E632RETI01E77A10PO19:MOVR2,#10H01E95113ACALLDELY;延时101EB22RET01EC7A06PO1A:MOVR2,#06H01EE5113ACALLDELY;延时201F022RET01F17A30P01B:MOVR2,#30H01F35113ACALLDELY;延时301F522RETORG0213H0213C002DELY:PUSH02H0215C002DEL2:PUSH02H0217C002DEL3:PUSH02H0219DAFEDEL4:DJNZR2,DEL4021BD002POP02H021DDAF8DJNZR2,DEL3021FD002POP02H0221D
