Abstract

The invention provides a subway tunnel deformation detection system, which comprises a laser radar, an encoder, an inertial navigation system, a synchronous acquisition system and an information fusion module which are arranged on a detection vehicle. The laser radar is used for detecting detection point information of a subway tunnel; the encoder is used for recording the driving mileage of a detection vehicle and generating counting pulses; the inertial navigation system is used for acquiring speed and position information of the detection vehicle in relative navigation coordinates; the synchronous acquisition system is used for collecting the detection point information of the subway tunnel, the counting pulses and driving mileage and the speed and position information of the detectionvehicle in the relative navigation coordinates; and the information fusion module is used for carrying out fusion and analysis on the information acquired by the synchronous acquisition system to obtain the deformation position information and deformation quantity of the subway tunnel. Therefore, the accurate measurement of the deformation position of the subway tunnel can be realized; and compared with the traditional detection mode, the provided system enables the detection efficiency to be improved.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a subway tunnel deformation detection system. Background technique [0002] In recent years, my country's urban rail transit industry has developed rapidly. However, problems such as tunnel deformation after the completion of the subway have seriously affected the safety of train operation. How to quickly and effectively detect the existing tunnels, so as to ensure the operation safety of the subway, has increasingly become the focus of attention of the majority of rail transit technicians. [0003] The deformation of the subway tunnel refers to the local deformation of the subway tunnel caused by the load of the ground and surrounding buildings and soil disturbance. Existing detection methods are generally based on manual work and small-scale detectors, which takes a long time to detect, and the operation efficiency is low. Contents of the invention [0004]...
