A data acquisition system for automatic monitoring of tunnel structure deformation

Abstract

The invention discloses an automatic monitoring data obtaining system for tunnel structural deformation. The automatic monitoring data obtaining system comprises a foreground system, a collecting system and a database server. The foreground system is internally provided with a data collecting module, a basic configuration module, a data view module and a virtual multi-serial port expanding module, and the foreground system is connected with the database server. The foreground system is sequentially in communication a data collecting system through the virtual multi-serial port expanding module, a communication network and an RTU module. Multiple virtual serial ports achieved in a multi-thread parallel communication mode through the multi-serial port expanding module are used for conducting multi-thread parallel communication and used for sending data packets requested by collection to the RTU module in a parallel mode. The foreground system analyses the measuring data packets from the RTU module and stores the packets into the database server. According to the automatic monitoring data obtaining system, the multi-thread parallel communication mode is adopted, parallel collection of data and high-speed data transmission operation are achieved, multiple sensors with different types are supported at the same time, expandability is good, the maintaining cost is low, the function of the system is simple, setting is simple and operation is convenient.

Description

technical field [0001] The invention relates to a tunnel monitoring and early warning system, in particular to an automatic monitoring data acquisition system for tunnel structure deformation monitoring, which belongs to the technical field of safety monitoring. Background technique [0002] With the rapid advancement of urbanization in China, rail transit will inevitably become an important tool for urban transportation, and there is a great demand for structural deformation monitoring projects during the operation of rail transit. During the construction of the subway, it may cause structural deformation or even damage to adjacent buildings (structures), underground pipelines (pipe culverts), underground engineering (subway tunnels, civil air defense fortifications, basements, etc.). At the same time, construction in the subway protection area may also cause deformation or even damage to the subway structure, which will affect the normal operation of the subway, or cause o...
