Abstract

The invention discloses a bridge data base station based on a millisecond-level time synchronization technology. The bridge data base station comprises an MCU control circuit, an SD card interface circuit used for caching data, a 4G communication circuit used for realizing data communication between a data base station and a remote server, an RS485 communication circuit used for realizing communication between the MCU control circuit and a displacement sensor, a time synchronization circuit used for synchronizing the displacement sensor, and a power supply management circuit used for supplyingpower to the above circuits. The MCU control circuit is connected with the SD card interface circuit, the 4G communication circuit, the RS485 communication circuit and the time synchronization circuit. A millisecond-level time synchronization technology is adopted, displacement sensors are arranged at all monitoring points of a bridge, all the displacement sensors on a data bus are synchronized through a bridge data base station, and 24-hour uninterrupted millisecond-level synchronization error real-time monitoring is achieved.

Description

Technical field[0001]The invention relates to the technical field of bridge monitoring, in particular to a bridge data base station based on millisecond-level time synchronization technology.Background technique[0002]In recent years, due to the rapid development of economy and traffic, the rapid increase in traffic volume and the phenomenon of over-limit and overload have become prominent in countries all over the world. With the rapid economic development, the requirements for traffic capacity are constantly increasing, and the aging and functional degradation of many bridges have shown an accelerated trend. In order to ensure the safety and durability of large-scale bridge structures, and reduce and avoid major losses, it is urgent to monitor and evaluate the working conditions and structural characteristic parameters of bridge structures.[0003]As the daily traffic of vehicles forms a fast-moving load on the bridge, the stress points of the bridge are constantly changing, resultin...
