大型集装箱检测系统管理站的任务需求分析与结构规划

由加速器周期性产生的Ｘ射线经前准直器成形为扇形脉冲束流，透过集装箱后再经过后准直器进入阵列探测器，再由前置放大器放大成形为电压信号送入采样保持电路，经多路选择器送去变换成为一组数字量，再经过一系列的预处理就可形成一列象素。由于集装箱是载于拖动装置上的，随着拖动装置的运动，这一列列的象素就可组成一幅完整的集装箱透视图，这样的一个完整过程由中心管理站统一控制和同步。本文介绍实时扫描数据获取与处理，并给

Task Analysis and Structure Scheme for Center Manager Station in Large Container Inspection System

LCIS works as follows: the accelerator generates beam pulses which are formed into fan shape; the scanning system drags a lorry with a container passing through the beam in constant speed; the detector array detects the beam penetrating the lorry; the projection data acquisition system reads the image system receives the projections and completes an inspection image of the lorry. All these works are controlled and synchronized by the center manage station. This paper will describe the process of the projection data acquisition in scanning mode and the methods of real time projection data processing. The task analysis and the structure scheme of center manager station is pressented in this paper. (
