Method, system and ground-based navigation beacon for monitoring building deformation using radio and television data broadcasting

Abstract

The invention discloses a building deformation monitoring method and system with radio and television data broadcasting and a ground-based navigation beacon. The system mainly comprises a broadcastingstation, a deformation monitoring terminal, a deformation monitoring center and a ground-based beacon navigation and positioning receiver. The ground-based navigation beacon transmits signals for thedeformation monitoring data. Besides, the method comprises: step one, a broadcasting station broadcasts differential navigation correction information; step two, the deformation monitoring terminal receives a satellite navigation signal and differential navigation correction information; step three, the deformation monitoring terminal acquires own precise positioning timing information; step four, the deformation monitoring terminal sends the own positioning timing information to the deformation monitoring center and / or the ground-based beacon navigation positioning receiver; and step five, the deformation monitoring center receives the data transmission signal to perform deformation monitoring on a building where the deformation monitoring terminal is located. The building deformation monitoring method and system and the ground-based navigation beacon are suitable for deformation monitoring of buildings and / or non-buildings such as mountains.

Description

Technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a building deformation monitoring method, system and ground-based navigation beacon using radio and television data broadcasting. Background technique [0002] According to the "Engineering Survey Code GB50026-2007", deformation monitoring refers to the displacement, settlement, tilt, deflection, cracks and related influencing factors (such as the displacement, settlement, inclination, deflection, cracks, etc.) of structures and their foundations, building foundation pits, or rock and soil within a certain range Groundwater, temperature, stress and strain, etc.) are monitored, and the process of deformation analysis and prediction is provided. [0003] In recent years, with the rapid development of the civil construction industry, various high-rise civil buildings and large buildings such as bridges and dams have continued to emerge. In order to prevent the damage caused b...

AI Technical Summary

Problems solved by technology

In the traditional building deformation monitoring technology, the deformation monitoring terminal needs to continuously send the "raw navigation observations" of satellite navigation to the deformation monitoring center, and the amount of communication data is relatively large. Generally, it is based on a dedicated regional wireless network, optical fiber or mobile communication. As a means of information transmission between systems, the network either cannot cover a large area, or the construction is expensive, or requires continuous payment of communication fees, which limits the large-scale application of deformation monitoring technology
