High Intensity D-T Fusion Neutron Generator (HINEG) is an accelerator-based D-T fusion neutron facility, which parameters of neutron yield is designed to be the best in neutron generators in China and could be operated in continuous and pulsed modes. A dual-mode control system has been designed to achieve remote monitoring and control for HINEG. Distributed control technology is adopted in this control system due to all the devices dispersed along the beam line in different locations. A dual-mode friendly operation interface is developed for operators to manage the devices expediently through the intranet. Additionally, a multi-objective multi-parameter safety interlock system configured with a Safety PLC is constructed to protect the devices, controllers and operators. The safety interlock system could be triggered by intelligent fault diagnosis system to terminate HINEG operation and alarm within tens of milliseconds if the interlocking constraints are broken. For the controllers and devices are operated under high voltages about 400kV, strong electromagnetic fields and nuclear radiation conditions, many anti-interference measures are taken in this control system.
