摘　　要：为了实现在舱室的高温环境中高精度的声源定位,提出了一种用于高温舱室的基于约束总体最小二乘法变速度迭代扫描声源定位系统。通过实验在高温房间内布置二元声音传感器模块,搭建数据采集系统,上位机获取结果并结合使用该方法进行声源定位实验,实验结果表明,在40 m×20 m×6 m的高温区域中,声速起伏范围为±20 m/s,通过变速扫描最后得到的定位结果比常规声速340 m/s下的定位结果的均方根误差减小了2.7 m左右。In order to achieve high-precision sound source localization in the high-temperature environment of the cabin,a constrained total least squares variable velocity iterative scanning sound source localization system for the high-temperature cabin was proposed.In the experiment,a binary sound sensor module was placed in a high-temperature room,and a data acquisition system was established.The host computer obtained the results,and the sound source positioning experiment was conducted by combining the method.The experimental results show that in the high temperature area of 40 m×20 m×6 m,the range of sound velocity fluctuation is ±20 m/s,and the final positioning result obtained by variable speed scanning is about 2.7 m smaller than the root mean square error of the positioning result under the conventional sound speed of 340 m/s.
