一种微机监控系统的功能设计

FUNCTION DESIGN OF COMPUTER CONTROL SYSTEM

介绍了采用上位机和下位机构成的微机监控系统所完成的对现场数据进行实时监控和管理的各种功能，分别说明了上位机和下位机的程序设计方法，讨论了上位机和下位机在数据传输中应注意的问题。为提高监测的实时性，系统选用上、下２台微机，下位微机的任务是实时进行监控并给上位微机传送现场数据，其任务的简单性使得系统的可靠性得到提高。上位微机实时接收下位微机传来的数据组成报表和分析数据，使得工作人员能够利用报表和数据来指导生产和管理。

The thesis intrduces various function which are fulfiled by a computer control systemconsisting of a up-computer and a down-computer.It the meantime,the program designingmethods of the up-computer and the down-computer are separately illustrated.The prob-lems of the data transfer between the up-computer and the down-computer are discussed.The system uses two computers to enhance the real-time performance of monitoring andcontrol system。The task of the down-computer includes monitoring and transmitting datato the up-computer.Therefore,the simplicity of its task makes it reliable,The up-computerconstitutes production report and data analysis through receiving data transmitted by thedown-computer.The workers can make use of the report and data to guide production andsupervision.
