Tunnel construction informatization dynamic monitoring system and monitoring method thereof

Abstract

The invention discloses a tunnel construction informatization dynamic monitoring system and a monitoring method thereof. The system comprises an industrial personal computer, a PLC (programmable logic controller) wireless controller, a high-configuration digital camera, a deformation monitoring sensitization part, digital display acquisition equipment, wireless transmission equipment and a dynamic design feedback device. The method includes: 1), controlling commands to be transmitted to the PLC wireless controller by a computer control main station and controlling the digital camera and the digital display acquisition equipment; 2), acquiring internal force monitoring data by the aid of the digital display acquisition equipment; and acquiring a deformation monitoring image via the deformation monitoring sensitization part by the digital camera; 3), transmitting a monitored value to the computer control main station by the aid of the wireless transmission equipment; 4), analyzing results by the computer control main station via a real-time analysis module; and 5), transmitting the analyzed results to the dynamic design feedback device, analyzing relative difference of the really monitored value and a standard value, and early warming in real time by an early warning module. The tunnel construction informatization dynamic monitoring system is scientific, safe and practical, the method is convenient, instant, fast and effective, and safety problems in construction monitoring of tunnels are avoided.

Description

technical field [0001] The present invention relates to a tunnel construction informatization dynamic design system and method, more specifically to DIC digital image correlation technology, wireless control and transmission technology, and also to a comprehensive evaluation and early warning technology, especially suitable for large tunnels in complex and harsh environments The real-time monitoring and information-based dynamic design are suitable for projects with high monitoring accuracy requirements. Background technique [0002] Due to the complex geological environment and lack of basic information in the construction of tunnels, the design of underground engineering cannot be completed in one step before construction starts. This is an important feature that distinguishes underground engineering from other civil engineering. Therefore, at present, the design and construction of tunnels in underground engineering widely adopt the information-based design-construction o...
