Title:
ENERGY DEGRADER CONTROL SYSTEM FOR SUPERCONDUCTING PROTON DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/103174
Kind Code:
A1
Abstract:
Disclosed is an energy degrader control system for a superconducting proton device. The control system comprises a PLC, an upper computer, a human-computer interface, a distributed I/O module, a graphite block, a servo controller, a grating ruler and a transmission mechanism, wherein the PLC is used for controlling an energy degrader; the upper computer is used for exchanging a complex operation function with the PLC by means of a bus; the human-computer interface is used for exchanging a parameter with the PLC by means of the bus; and the distributed I/O module is connected to the PLC by means of the bus. The control system has two control modes, i.e. a local control mode and a remote control mode. A double closed-loop redundant control system is constructed by taking the PLC as a core component of the energy degrader control system, by using PROFINET, OPC-UA, distributed I/O and servo control technology, and by combining the application of a touch screen and an industrial personal computer, such that the system operates reliably, responds rapidly, has a high precision and is highly integrated and intelligent, thereby satisfying the requirements for the energy degrader control system.
