摘要

摘要: 为了增大惯性约束聚变玻璃靶丸的磁悬浮力，通过热处理工艺对其表面金属氧化物涂层进行晶态调控从而增强磁性能的方法对热处理温度控制精度要求极高，需要从多方面对温度进行把控。目前基于圆图记录仪的温度测量手段已经不能满足惯性约束聚变对热处理温度开展实时多模态数据分析的要求。提出一种针对精密热处理过程温度测量的多模态重构方法，首先将精密热处理过程的温度数据进行数字化传输与存储，然后在计算机中进行多模态解析与重构，最后基于空间拓扑关系与特征参数标定结果，利用Corexy机构实现热处理温度的多模态重构。结果表明所提方法可以实现对温度调控过程的单一化模态分离与多模态重构，实现误差一般小于5%。

Abstract: In order to increase the magnetic levitation force of Inertial Confinement Fusion (ICF) glass target pellets, the temperature control accuracy of heat treatment is required to be very high by means of crystal state regulation of metal oxide coating on the surface of the glass target pellets through heat treatment process so as to enhance the magnetic properties.At present, the temperature measurement method based on circular graph recorder cannot satisfy the requirement of ICF when analyzing the heat treatment temperature in real time and multimodal. This paper proposes multimodal reconstruction method for precision heat treatment temperature measurement. First, the process temperature data is digitalized and transferred, and then reconstructed and multi-modally analyzed in the computer, finally based on spatial topological relations and characteristic parameters calibration results, using Corexy mechanism to realize multimodal reconstruction of heat treatment temperature. The results show that the proposed method can realize the single mode separation and multimodal reconstruction of the temperature control process, and the implementation error is generally less than 5%.This method can provide abundant heat treatment temperature data for precise physics experiments.
