摘要
目前针对气体泄漏热成像检测系统性能的相关评价技术还不够成熟,相应评价指标的测试系统及其测量方法尚无系统的研究报道。而常规热成像系统的性能评价方法难以直接用于评价气体泄漏热成像检测系统对泄漏气体的探测能力,本文结合泄漏气体特性及各测试系统的特点,设计了一种可测量多类性能指标的气体泄漏热成像检测系统性能的测试评价系统,并以乙烯和甲烷气体为检测目标在实验室环境中分别对 NECL、MRGC和 MDGC三种评价指标进行了实验测量,结果表明了测试评价系统的可行性和实用性。
Abstract
At present, the technology for the performance evaluation of gas leak thermal imaging detectors is not sufficiently well-developed, and there is no systematic research report on the test systems or methods of the corresponding evaluation index. However, it is difficult for the performance evaluation methods of conventional thermal imaging cameras to directly evaluate the detection capabilities of gas leak thermal imaging systems. We designed a test and evaluation system that can measure the performance of gas leak thermal imaging systems with multiple types of performance indicators. NECL, MRGC, and MDGC were measured experimentally in a laboratory environment with ethylene and methane gas as the detection target. The experimental measurements verify that the test evaluation system is feasible and practical.
