Bridge displacement monitoring system and bridge displacement monitoring method

Abstract

The invention discloses a bridge displacement monitoring system and a bridge displacement monitoring method. The system comprises a bridge displacement monitoring device, a communication device, a data management center and a user terminal, wherein the bridge displacement monitoring device transmits monitored bridge signals to the communication device through a wireless communication module; the communication device transmits the signals to the data management center through the wireless communication module; the data management center calculates the signals and then transmits the calculated signals to the user terminal. The bridge displacement monitoring system and the bridge displacement monitoring method have the benefits that real-time and long-term monitoring of lateral displacement, longitudinal displacement and vertical displacement of a bridge can be realized through measurement stations and a reference station which are provided with built-in GNSS receivers, safe and sound monitoring and prewarning of the bridge structure are realized; the measurement stations and the reference station can be synchronously measured without intervisibility between the measurement stations and the reference station; the signals are transmitted in a wireless manner, and high-precision three-dimensional coordinates can be provided in real time, so that manual testing time is shorted, the bridge management can realize automation and intelligentizing, and bridge safety monitoring and maintenance efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bridge structure health monitoring, in particular to a bridge displacement monitoring system and a monitoring method thereof. Background technique [0002] With the development of our country's social economy, the progress of science and technology, and the needs of transportation, many different types of bridges have emerged as the times require. Bridges are often hubs on traffic routes, directly related to social public safety, and their service life often lasts for decades or even hundreds of years. If potential safety hazards occur and fail to be warned in time, in extreme cases, it is easy to cause catastrophic accidents. Huge losses have been caused to people's lives, property and social resources. Correspondingly, the "National Medium and Long-term Science and Technology Development Plan Outline" has also incorporated public safety, health and risk monitoring into the national strategic developmen...

Problems solved by technology

The physical sensor method can only observe limited local deformation. The conventional geodetic method has a large workload, low efficiency, is greatly affected by the climate, and requires the monitoring point to be in sight with the base point. It is difficult to monitor the bridge in real time, accurately, and wirelessly. Measurement
