Abstract

The invention discloses an analog-signal interlocking protective controller used for a neutral-beam injector. The controller includes an analog-signal input module, a threshold setting module, a control bus, a communication module, an interlocking protective logic control module and a control-signal output module. An FPGA is adopted as a main controller of the analog-signal interlocking protective controller to receive external commands and manually set commands of the communication module and through control of the analog-signal input module and the threshold setting module, high-speed and reliable output of interlocking protective control signals of a hardware level is realized. The analog-signal interlocking protective controller used for the neutral-beam injector is capable of solving problems of high-speed interlocking protection and remote control, in which analog signals on a fusiondevice take part so that remote and local reliable control of interlocking protective control logic is realized. The controller is flexible to apply and is also widely applicable to other control application fields of interlocking protective control which has high analog-signal protective requirements.

Description

technical field [0001] The invention relates to fusion device protection technology, in particular to an analog signal chain protection controller technology for a neutral beam injector system. Background technique [0002] Today, with the increasing demand for energy, nuclear fusion, as a clean energy source, has attracted more and more attention. The neutral beam injector is one of the important heating means of the magnetic confinement nuclear fusion device. There are interlocking protection applications of a large number of analog signals in the neutral beam injector control system. Fast chain protection of analog quantity is a necessary means for safe and reliable operation of control system, especially in the control system of nuclear fusion device. [0003] The neutral beam injector in the important auxiliary heating system of the nuclear fusion device needs the transmission and transformation of various analog signals. In the actual neutral beam injector contr...
