Long-term Monitoring System for Bridge, Dam, and Slope

FTJC-4 Dam and Slope Long-term Monitoring Automatic Monitoring System- Micro-Deformation Measurement System

I. System Overview

This system adopts the photoelectric imaging method, consisting of photoelectric targets, an imaging measurement system, a GPRS wireless network transmission system, and control center data acquisition and analysis software. It analyzes the micro-deformation of the measured target by capturing the image formed by the photoelectric target fixed on the object on the photosensitive device.

The system enables convenient remote monitoring via GPRS wireless networks, making it suitable for long-term monitoring and short-term observation in unmanned, hard-to-wire field environments. It features intelligent functions such as remote monitoring, automatic measurement cycles, real-time evaluation of measurement results, and real-time display of deformation trends. Field data can be collected on any internet-connected computer. This product can be applied in railway and highway bridge monitoring, landslide monitoring, dam deformation monitoring, subway monitoring, high-rise building monitoring, and more, making it an ideal system for automatic building deformation monitoring.

It can not only measure the micro-deformation of targets but also simultaneously monitor target vibrations. It provides parameters such as forced vibration frequency, natural frequency, and amplitude of the measured target, and through spectrum analysis, it can derive parameters like impact coefficient and power spectrum. The hardware, software, and accessories of the system, including their quantities and specifications, can be customized according to the actual needs of the project.
