摘　　要：为克服传统的离线采样分析的不足,采用近红外检测方式对热脱水纤维素硝化脂(Nitrocellulose,NC)含水量进行检测。分析热脱水高危环境对基于近红外的脱水NC含水量检测的应用约束,并从应用安全性和检测准确性方面分析并选取有效措施保证该环境下近红外检测的实现。试验数据表明,近红外方式可以完成脱水纤维素硝化脂的安全、准确检测。将近红外检测平台与PLC控制平台相结合,实现了现场控制级对NC水分含量的在线准确检测。NIR detecting mode is adopted to detect moisture-content of NC, dehydrated with hot wind, avoiding the shortage of traditional sampling- analyzing offline. The surroundings, dehydrating Nitrocellulose with hot wind in it, is very dangerous. The restrictions on the application of the method of measuring content of moisture to nitrocellulose, dehydrated by hot wind, based on NIR in the surroundings, told above, is analyzed. With the security and the veracity of application of NIR analyzed, effective measure is chosen to insure the achievement of measuring with NIR. The test data shows that the NIR method can deal with the measure of moisture-content of NC safely and accurately. The method to integrate the platform of NIR surveymeter with PLC control system is designed to achieve the application of measure of moisture- content of NC accurately online with field controller.
