摘要
介绍了一种基于以太网的微机调度模拟屏控制系统。由于以太网具有应用广泛、成本低廉、通信速率高、通用性好、可连接节点多、扩展性强等特点,使得该系统与同类产品相比,具有强大的优势。同时该系统也具有一些自己独特的优点,如断电之后上电,能够恢复到原来的状态,以及事故报警功能。降低了事故造成的影响,并能预防重大事故的发生,具有很强的实际运用价值。重点介绍了该系统的软硬件结构以及储存其重要信息的93L C4 6的编程方法,并指出了容易出错的地方。
The Paper introduces ethernetbased control system of microcomputer scheduling and simulation screen.The system possesses great advantages including widely applicable,cheap cost, high communication rate,a great deal of nodes is available,and mighty expansibility. On the other hand,the system has special features.For example,it can recover to its original state after cutting off, and it can give an alert if there is an accident.These features can reduce the damage of accidents, and prevent the happen of fatal accidents.It is of great actual value.With an emphasis on it,software and hardware′s stucture and a method of programming of 93LC46,which stores important information are introduced. Emphasize some aspects which likely to make a mistake.
