Example Embodiment

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0019] A bridge safety and health monitoring system includes a sensor group, a digital module group, a data concentrator and a monitoring center.

[0020] The monitoring center conducts data interaction with the data concentrator through the wireless network, and the data concentrator collects data from the field monitoring equipment through the fieldbus RS485 network.

[0021] The bridge safety and health monitoring system automatically monitors structural parameter information such as stress and strain, structural vibration, winding, cracks, settlement, and leakage of bridges, elevated roads and large overpasses through equipment installed on bridges, elevated roads and large overpasses. Then it is sent to the monitoring center through data collection and ...

Abstract

The invention discloses a bridge safety health monitoring system. The bridge safety health monitoring system comprises a sensor group, a digital module group, a data aggregator and a monitoring center, wherein the sensor group is used for monitoring structural parameters of a bridge; the digital module group is used for converting a multi-channel analog signal into a corresponding digital signal; the data aggregator is used for acquiring data of the digital module group through a field bus network; the monitoring center is used for performing data interaction with the data aggregator through a wireless network; the digital module group is connected with the data aggregator; the data aggregator is connected with the monitoring center; the sensor group comprises n sensors; the digital module group comprises n digital modules; the output ends of the sensors are connected with the input ends of corresponding digital modules; n is a positive integer. By adopting the bridge safety health monitoring system, the safety of bridge monitoring is enhanced, and high reliability and availability are achieved.

Description

technical field [0001] The invention relates to a bridge safety and health monitoring system, which belongs to the technical field of large old bridge safety monitoring. Background technique [0002] With the continuous deepening of modern theoretical research and the maturity and perfection of bridge construction technology, bridges built with various new materials and new techniques emerge in endlessly, but as time goes by, any highway bridge will eventually become an old bridge; The structure used will inevitably suffer from various damages due to various reasons, and there are various degrees of disease and defects, which require maintenance, reinforcement and transformation. Before maintenance and reinforcement, it is necessary to carry out reasonable inspection and evaluation, obtain the actual working condition and bearing capacity of the bridge, analyze the causes of disease and damage, and propose effective maintenance and reinforcement measures. Highway and bridge...
