BJFT-3C Long-term Monitoring System for Bridges and Large Structures
1. System Overview:
The BJFT-3C long-term monitoring system for bridges and large structures is composed of high-precision sensors, data transmission networks and background data monitoring and processing software, integrating current advanced computer technology, microelectronics technology, wired/wireless network communication and telemetry technology, and precision sensing technology. Various sensors of this system have high sensitivity, good stability, sturdiness and durability, are easy to install and use, and meet various requirements of field engineering sites. They can automatically measure and detect deformations of various solid structures, concrete structures, steel structures and so on in real time. The sensors, combined with the supporting sampling and analysis software of the system, can realize deformation monitoring of engineering structures such as bridges, roads, foundations and the like.
2. Bridge Monitoring or Detection Contents:
1) The magnitude of test load;
2) The distribution and magnitude of stress on the cross-sections of structural members, and the magnitudes of support reactions, thrust and the like;
3) Various static deformations of the structure, including horizontal displacement, deflection, relative slip, rotation angle and the like. Local damage phenomena of the structure, such as the distribution, width and depth of cracks and the like;
4) Dynamic characteristics of the structure, such as natural vibration frequency, period, attenuation characteristics and the like, as well as dynamic stress, dynamic displacement, velocity and acceleration and the like of the structure under dynamic loads.
3. System Composition:
The BJFT-3C long-term monitoring system for bridges and large structures is composed of self-developed intelligent digital sensors, wired or wireless transmission networks and background intelligent analysis and monitoring software.
