Control bus system for neutral beam injector system

Abstract

The invention discloses a control bus system of a neutral beam injector system. The control bus system comprises a bus backboard, a controller card, an equipment card, an expansion card, a power supply module, a case, and other assemblies, wherein the bus backboard is arranged in the middle of the case, a system control bus is fixed on the bus backboard; the controller card, the equipment card and the expansion card are inserted on the bus backboard; the controller card and the equipment card are subjected to mutual operation and data exchange through the system control bus of the bus backboard, the expansion card is used for expanding the system control bus to a plurality of cases by virtue of an expansion cable; the power supply module provides a power supply for the controller card and the equipment card. The control bus system realizes integration of functional board cards by virtue of the control bus backboard by adopting a modular design, and is compact in structure; the anti-electromagnetic interference is easily improved; the difficulties of excessive interlocking protection wiring and incapability of performing online configuration on interlocking protection logics in the neutral beam injector system are solved; the control bus system has a hot plug function, and can be widely applied to the fields of field real-time control, computer control, industrial automation and the like.

Description

technical field [0001] The invention relates to computer control technology, in particular to the system control technology of an auxiliary heating neutral beam injector in the field of fusion. Background technique [0002] In today's increasingly intensified energy demand, the continuous and stable supply of energy is a reliable guarantee for the sustainable development of a country and nation. Fusion energy is considered to be an inexhaustible source of clean energy. Neutral beam injector (NBI) is an important auxiliary heating system for controllable magnetic confinement fusion devices. Although there are differences in the specific structures of NBIs used in different fusion devices, their system composition and working principles are basically the same. The typical structure of NBI includes power supply system, control system, water cooling system, and beamline composed of ion source, neutralization chamber, ion deflection system, power measurement target, vacuum pump...

AI Technical Summary

Problems solved by technology

However, the NBI system especially has its own unique characteristics of control requirements. During the construction process of the system, it is necessary to carry out chain protection for many signals scattered in the physical location of the NBI system. The signal wiring in the implementation process is too much, and the anti-electromagnetic interference ability is poor.

In order to realize the monitoring and protection of different systems, it is necessary to write proprietary control logic software, which cannot meet the high real-time control requirements of logic monitoring

Existing logic protection modules are physically dispersed, and there are many wirings between modules, which are realized by hardware circuits and cannot be programmed for logic

When repairing the hardware modules of the control system, it must be shut down, and hot swapping cannot be realized, which affects the logic control process of the system
