The control system of the large scientific device is a link for linking and coordinating the subsystems of the large scientific device and is also a platform for debugging and running the large scientific device. At present, a control system of a large scientific device is a distributed control system based on a network and consists of a management layer, a front-end control layer and a control local area network. The management layer consists of display equipment and a server and provides a Human Machine Interface (HMI) and various service functions; the front-end control layer receives the control of the management layer through the control local area network, forms a client server mode with the management layer, and the device controller completes the tasks of state monitoring and control, data calculation, data collection and the like of the front-end device.

With the development of technology, most front-end equipment of a large scientific device is intelligent equipment, and communication modes of the equipment can be divided into two types; one is that the front-end equipment directly adopts an Ethernet communication mode, and the other is that the front-end equipment adopts a serial port communication mode, and serial port communication can be converted into Ethernet communication through a serial server, so that all the front-end equipment can be uniformly controlled through the Ethernet mode. Because the control local area network extends downwards to the front-end equipment, communication wiring is very convenient, but all the front-end equipment are controlled through a single Ethernet, network load is large, data exchange among the equipment is too frequent, and the information safety problem exists. In addition, most of the existing equipment controllers are industrial personal computers arranged on a control field, rapid deployment of the system is not facilitated, and maintenance is not convenient enough.
