Abstract

The invention relates to an entire deformation detection system of a subway tunnel and belongs to the field of a tunnel engineering monitoring technology. The system integrally comprises a plurality of instrument stations distributed on the inner wall of a tunnel and stop-level monitoring systems in tunnel stops, image acquisition terminals in all the instrument stations are connected into a network through an RS485 bus and connected with monitoring computers in the stop-level monitoring systems, so that coordinate displacement change information of adjacent instrument stations, which is acquired and processed by the image acquisition terminals, can be sent to the stop-level monitoring systems and tunnel deformation conditions between two stops are summarized and analyzed by the monitoring computers integrally. In the invention, a network sensor technology and an image identification technology are used for the online real-time deformation monitoring of operating subway tunnels for the first time, the deformation condition of the tunnels can be analyzed according to tunnel deformation data, and disasters caused by serious deformation conditions of the tunnels can be alarmed in time.

Description

technical field

[0001] The invention relates to a system in the technical field of tunnel engineering monitoring, in particular to an overall deformation detection system of a subway tunnel. Background technique

[0002] my country's tunnel management and maintenance technology lags behind, maintenance technical specifications still need to be improved, and more research is needed on long-term tunnels. Although the technology of a complete set of tunnel operation monitoring system has been introduced in many tunnels in China, the effect is not satisfactory. The main reason is that the control mode is not practical, and it is rarely used in long tunnels. Therefore, it is extremely important and urgent to study the operation and maintenance technology and intelligent management system of subway tunnels. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an overall deformation detection system ...
