针对传统的热风炉测温监测系统测量范围小、精度较差等问题,本文提出了将分布式光纤测温系统优化后应用于热风炉监测,给出了该系统的组成结构和流程设计,提出了螺旋式缠绕热风炉的布设方式.优化使用平移算法对光信号进行光纤色散补偿.实验结果表明,使用优化算法后,去噪效果好且补偿了系统的光纤色散效应,系统平均误差由1.12下降到了0.35℃,测温精度有所提高.综上,优化后的分布式光纤测温系统能有效监测热风炉的连续温度,可以投入到实际测温中使用.
Optimization and Application of Distributed Temperature Sensing System in Hot Blast Stove Monitoring
Aiming at the problems of traditional hot blast stove temperature measurement monitoring system,such as small measurement range and poor accuracy,this paper proposes to optimize the distributed temperature sensing system and apply it to hot blast stove monitoring.The composition structure and flow design of the system are given,and the layout of spiral winding hot blast stove is proposed.The translation algorithm is used to compensate the optical fiber dispersion for light signal.The experimental results show that,after using the optimized algorithm,the denoising effect is good and the fiber dispersion effect of the system is compensated.The average error of the system is reduced from 1.12 to 0.35℃,and the temperature measurement accuracy is improved.In conclusion,the optimized distributed temperature sensing system can effectively monitor the continuous temperature of the hot blast stove and can be used in actual temperature measurement.
