Bridge safety online monitoring system

Abstract

The invention discloses a bridge safety online monitoring system, which comprises an optical fiber sensing analyzer, monitoring equipment, an optical path connecting box, a power supply module and a wireless transmission module, wherein the optical path connecting box, the power supply module and the wireless transmission module are connected with the optical fiber sensing analyzer, the monitoringequipment comprises a server and a large LED screen connected with the server, and the optical fiber sensing analyzer accomplishes information interaction with the server through the wireless transmission module. The invention solves a problem existing in the prior art that the dependence on manual inspection in the traditional bridge detection technology has limitations in practical applications, and provides a bridge safety online monitoring system. The bridge safety online monitoring system can respond timely to emerged potential safety hazards when being applied, and achieves real-time monitoring for various parameters such as the temperature, stress, vibration and crack variations of key parts of a bridge.

Description

technical field [0001] The invention relates to bridge safety monitoring equipment, in particular to an online bridge safety monitoring system. Background technique [0002] The traditional bridge inspection technology is to evaluate the safety status of the bridge structure through manual visual inspection or information obtained by means of portable instrument measurement. Manual bridge inspections are divided into regular inspections, regular inspections and special inspections. However, the manual bridge inspection method has great limitations in practical application. The shortcomings of traditional inspection methods are mainly manifested in: it requires a lot of manpower and material resources and has many inspection blind spots, which is especially prominent for modern large bridges; it is highly subjective and difficult to quantify; it lacks integrity. It can provide partial detection and diagnosis information, but cannot provide overall and comprehensive structur...

Problems solved by technology

[0004] The present invention solves the problem that the traditional bridge detection technology in the prior art has limitations in actual application by relying on manual inspection, and provides a bridge safety online monitoring system, which can respond to hidden safety hazards in time when it is applied, and realizes Real-time monitoring of various parameters such as temperature, stress, vibration, and gap changes in key parts of the bridge, and the health of the bridge can be judged by the analysis device based on the monitoring data. The bridge maintenance staff can truly understand the safety status of the bridge in real time. Various activities on the bridge provide an effective reference basis, and then ensure the safety of the bridge by providing the required early danger warning and damage assessment, thereby greatly enhancing the survivability of the bridge
