1、湖南工程学院课程设计课程名称过程控制课题名称储槽液位控制系统专业自动化班级0701学号3姓名李敬杰指导教师沈细群李亚2010年12月24日0设计内容与设计要求设计内容：在工业生产过程中，液体贮槽设备如进料罐、成品罐、中间缓冲容器、水箱等应用十分普遍，为保证生产正常进行，物料进出需均衡，以保证过程的物料平衡，因此工艺要求贮槽内的液位需维持在某个给定值上下，或在某一小范围内变化，并保证物料不产生溢出，要求设计一个液位控制系统。设计要求：1）确定系统设计方案；2）选择相应的仪器设备；3）MCGS软件组态相应的监控画面；4）完成控制算法程序设计；5）在DDC控制

2、装置中进行调试；0主要设计条件假设贮槽设备是一水箱，生产工艺要求水箱液位应保持在，设计控制系统满足该要求。说明书格式1.课程设计任务书2.目录3.系统总体方案选择与说明4.系统结构框图与工作原理5.各单元硬件设计说明及计算方法6.软件设计与说明（包括流程图）7.调试结果与必要的调试说明8.使用说明9.程序清单10.总结11.参考文献附录附录A系统原理图附录B程序清单0进度安排设计时间为两周第一周星期一、上午：布置课题任务，讲课及课题介绍下午：借阅有关资料，总体方案讨论星期二、确定总体设计方案星期三、选择相应的仪器设备，进行控制算法设计星期四、控制算法编程
