  The quality of underground space information data has become a major problem
endangering the safety of underground space. After research and analysis, we
found that the current high accuracy information data remote detection methods
are limited to the detection of overground spaces objects, and are not
applicable to the detection of various information data in underground space.
In this paper, we analyze the spectral properties of the fractional-order
differential (FDO) operator, and establish mathematical model of remote
transmission and high-precision detection of information data, which realizes
the functions of high-precision and remote detection of information data. By
fusing the information data to detect the mathematical model in a long distance
and with high accuracy, A mathematical model has been established to improve
the quality of underground spatial information data. Through the application in
engineering practice, the effectiveness of this method in underground space
information data detection is verified.
