摘　　要：本工作为1台10 MeV辐照用电子直线加速器研制控制系统。该控制系统采用分布式网络控制,由多个子系统构成。硬件采用SIEMENS PLC芯片和监控计算机,PLC间采用PROFIBUS、MPI等高速总线进行连接,与监控计算机采用以太网连接,使用TCP/IP协议,能在互联网上远程监视和维护,进行网络控制。软件采用STEP 7和C语言等编写,对各子系统及子系统间连接均采用独立的数据块和功能函数块。部分硬件功能由软件来实现,使得整个系统更易于测试、制造和维护升级。Control system of the 10 MeV electron linac using Distributed Control System(DCS) was studied. The hardware of control system consists of four SIEMENS PLCs and monitor computer, the software bases on STEP 7, Labwindows/CVI and SQL Server. The bus between the monitor computer and the main PLC is 100M industrial networks, between PLCs is MPI bus, between PLC and remote partner is PROFIBUS, between PLC and terminals is RS485/422. The software of control system can provide a friendly human machine interface to operate the machine, protect the human and equipment from risk, and storage the status of the accelerator real time to the database. The monitor and maintenance of the linac can been carried out not only on local computer or local network, but also in internet.
