摘要
从分布式光纤测温系统的测温和定位原理出发,结合产品现状和煤矿井下的特殊情况,分析了系统空间分辨率、温度测量范围、温度测量准确度、定位准确度、单通道测试时间、报警预警功能等技术参数的特点,提出了建议性的技术要求并制定了合理的检测检验方法。
Based on the principle of temperature and positioning measurement of the distributed optical fiber temperature measurement system,the characteristics of the technical parameters such as the spatial resolution,the temperature measurement range,the accuracy of temperature measurement and positional resolution,the single channel test time and the fire warning function are analyzed in combination with the product status and the special situation of the coal mine.Technical requirements are suggested and reasonable testing and testing methods are developed.
