Tunnel displacement detecting system and detecting and calculating method

Abstract

The invention, which belongs to the technical field of tunnel monitoring, relates to a tunnel displacement detecting system and detecting and calculating method. The system comprises a plurality of integrated ranging units, a plurality of MCU control units, a plurality of PLC transceiver modules and an upper computer unit. Each integrated ranging unit is connected with one MCU control unit and onePLC transceiver module successively to form a measuring unit. The MCU control units are configured to process data collected by the integrated ranging units and transmit the data to the PLC transceiver modules; the PLC transceiver modules send the information to the upper computer unit; and the upper computer unit aggregates the data transmitted from the plurality of measuring units and displaysthe data. According to the invention, with introduction of PLC communication, a defect that the communication quality is affected by wireless signal attenuation in a tunnel, especially a long tunnel is overcome by combining the wireless module. Two kinds of different analysis methods are employed for different detection data; each new measuring value is added into the database according to each method and new data are learned continuously; and the data analysis capability is optimized.

Description

technical field [0001] The invention belongs to the technical field of tunnel monitoring, and relates to a tunnel displacement detection system and a detection calculation method. Background technique [0002] Monitoring and measuring in tunnel construction is a commonly used method for collapse prediction. In the tunnel monitoring and measurement project, the settlement of the tunnel vault is an important basis for judging the stability of the surrounding rock and guiding the construction, and is a must-measure item required by the tunnel and underground engineering construction specifications. [0003] At present, there are many researches on tunnel safety monitoring in foreign countries, but affected by various factors, the tunnel automatic monitoring system has yet to be matured, and the settlement of the vault still adopts the method of manual detection mainly and online real-time monitoring as a supplementary method. There is still a lot of research space for automati...

AI Technical Summary

Problems solved by technology

Domestically, it is relatively lagging behind in this regard, and many of them still adopt the method of manual inspection to monitor the safety of tunnels.

There are deficiencies such as poor real-time data, large interference with construction during the detection process, dangerous measurement work, high measurement costs, and poor unreliability of measurement data.
