The control and data acquisition system of a laser in-vessel viewing system

Rita C Pereira, Nuno Cruz, C Neri, M Riva, C.A.F Varandas2000年Fusion Engineering and DesignIF 1.7出版社

AbstractThis paper presents the dedicated control and data acquisition system (CADAS) of a new laser in-vessel viewing system that has been developed for inspection purposes in fusion experiments. CADAS is based on a MC68060 microprocessor and on-site developed VME instrumentation. Its main aims are to simultaneously control the laser alignment system as well as the laser beam deflection for in-vessel scanning, acquire a high-resolution image and support real-time data flow rates up to 2 Mbyte/s from the acquisition modules to the hard disk and network. The hardware (modules for control and alignment acquisition, scanning acquisition and monitoring) as well as the three levels of software are described.

本論文は、核融合実験における検査目的のために開発された、新しいレーザー容器内視認システム用の専用制御・データ収集システム(CADAS)について述べるものである。CADASは、MC68060マイクロプロセッサと、現場で開発されたVME計測機器に基づいている。その主な目的は、レーザーアライメントシステムと容器内走査用レーザービーム偏向を同時に制御し、高解像度画像を取得し、取得モジュールからハードディスクおよびネットワークへの最大2Mバイト/秒のリアルタイムデータ転送速度をサポートすることである。ハードウェア(制御・アライメント取得用モジュール、走査取得・監視用モジュール)ならびに3レベルのソフトウェアについて詳述する。
