反应堆物理启动试验设备信息共享系统研究

为了解决反应堆物理启动试验设备获取物理参数的准确性和实时性问题，提出建立一种物理启动试验设备信息共享系统，实现物理参数和试验数据的信息共享。利用以太网通讯技术，建立数据采集系统、物理启动监控平台和远程可视化系统之间的以太网通讯结构，形成客户端/服务器通讯模式，并采用Modbus TCP/IP通讯协议实现在监控平台实时共享物理参数的功能；利用局域网构建技术，构建物理启动监控平台与物理启动试验各个设备之间的星状网络结构，形成一个中心节点和若干分节点组合的方式，并采用RS-485串行通讯协议使得每个节点能在线显示反应堆物理参数和物理试验结果，实现反应堆操作人员、物理启动试验人员和远程监控人员同时共享启动试验数据的功能。

Information Sharing System of Reactor Physical Startup Experiment Devices

Information Sharing System is proposed in order to solve the problem about the accuracy and real-time of physical parameters obtained from reactor physical startup experiment devices. Ethernet communication structure is established among data acquisition system, physical startup monitoring platform and remote visualization system by using Ethernet communication technology, meanwhile, the client-server paradigm is established, and the physical parameters sharing function of the monitoring platform is realized by using Modbus TCP/IP protocol. By using LAN construction technology, star-shaped network structure among physical startup monitoring platform and physical startup experiment devices is established. The physical parameters and experiment results are displayed in each device by using RS-485 serial communication protocol, and the experiment data are shared among reactor operator, physical startup tester and remote monitor.
