Monitoring and early warning system applied to bridge

Abstract

The invention provides a monitoring and early warning system applied to a bridge. The system comprises a power supply module, a force collection and analysis module, a GPRS gateway, a remote monitoring center, a communication gateway and a bridge repair server. The power supply module comprises a city power supply, a transformer and a voltage stabilizer. The output end of the city power supply is connected with the input end of the voltage stabilizer through the voltage stabilizer. The output end of the voltage stabilizer is connected with the input end of the force collection and analysis module. According to the monitoring and early warning system applied to the bridge, data collected in real time from all parts of the bridge are conveniently summarized and analyzed; the analysis result is accurate; the probability of false alarms can be reduced; when the stress on one or more places of the bridge is too large, the system automatically carries out on-site alarm and remote alarm, can be timely maintained, and is convenient, simple and practical; and the monitoring and early warning system applied to the bridge has the effect of double storage, which improves the safety of data storage.

Description

technical field [0001] The invention relates to the technical field of bridge monitoring, in particular to a monitoring and early warning system for bridges. Background technique [0002] Bridges play an important role in people's lives. Bridges bring convenience to our production and life, but at the same time there are many hidden safety hazards. For example, after a bridge has been used for a long time, the stiffness and bearing capacity of the bridge will be attenuated to varying degrees, so it is particularly important to monitor the health parameters of the bridge, especially to monitor the stress of the bridge. [0003] However, the traditional bridge monitoring system is prone to false alarms, and when the force on one or more places of the bridge is too large, it cannot automatically perform on-site and remote alarms, which is not convenient for timely maintenance; secondly, the traditional bridge monitoring The system cannot achieve the effect of dual storage. T...
