Abstract: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.
