一、概述 在测控系统和工程应用中,常遇到若干工作同时进行的情况。因而分布式多微机控制成了一种常见的控制方式。 将微机应用于工业现场物料实时管理中,能大大提高物料计量的精度与称量的速度,同时还可完成各种信息报表的打印输出。本系统我们选择了研华工控IPC-286机作为分布式系统中的主、从控制单元,选择PCL-745通信卡作为网络中物理层,构成一个物料实时管理信息系统。该系统具有实时显示系统状态
First, an overview In the measurement and control systems and engineering applications, often encountered a number of work at the same time. Thus distributed multi-computer control has become a common control. The microcomputer used in real-time management of industrial field materials, can greatly improve the accuracy of material measurement and weighing the speed, but also to complete a variety of information report printout. The system we chose Advantech IPC IPC-286 machine as the main distributed system, from the control unit, select the PCL-745 communication card as the network physical layer, constitute a real-time management information system. The system has real-time display system status
