【摘要】 介绍一台12MeV,3kA,60ns直线感应加速器测控系统,一个基于Novell LAN的集中控制、分散采集数据的系统。系统由三个主要子系统组成。第一个子系统由一台上位PC机和由Bitbus相连的三台工控机组成,用于加速器运行状态和记录慢信号。200多台为束传输场供电的恒流源由第二个子系统测控,该子系统由一台PC机和置于每台恒流源内部的单片机单元、经光电隔离串接而成。快信号由第三个子系统记录处理。500 MHz～1 GHz带宽的示波器和多通道VXI波形记录仪经IEEE488连接到一台PC机上。所有数据都可传到工作站进一步处理。系统界面友好、易于操作。更多还原

【Abstract】 A control and monitoring system for a 12 MeV, 3 kA, 60 ns induction linac is presented. It’s a centralized control and distributed sampling system based on a Novell LAN. First of the three main subsystems consists of a supervisory PC and three front industrial control computers connected via Bitbus and is used for running the accelerator and recording slow signals. More than 200 current regulators for beam transport magnets are manipulated by the second subsystem with a PC and single chips inside the regulators connected serially through optical-electrical isolated interfaces. The fast signals are recorded and processed by the third subsystem. The oscilloscopes of 500 MHz- IGHz bandwidth and a 64-channel VXI waveform recorder are controlled by a PC via IEEE488. All the data acquired can be sent to a workstation for further analysis. The user-friendly interface makes the system easy to operate.更多还原
