Bridge health monitoring system based on acoustic emission technology

Abstract

The invention discloses a bridge health monitoring system based on an acoustic emission technology. The bridge health monitoring system comprises a plurality of acoustic emission data acquirers, an acoustic emission signal processor, a monitoring platform system, a CAN bus and the internet, wherein the acoustic emission data acquirers are connected to one end of the CAN bus in series; the other end of the CAN bus is connected with the acoustic emission signal processor; the acoustic emission signal processor is connected with the monitoring platform system through the internet; each acoustic emission data acquirer consists of an acoustic emission sensor, a signal acquirer and a CAN bus transceiver, the output end of the acoustic emission sensor is connected with the input end of the signal acquirer, the output end of the signal acquirer is connected with the input end of the CAN bus transceiver, and the output end of the CAN bus transceiver is connected with the CAN bus. The bridge health monitoring system has the advantages that with adoption of the acoustic emission sensors, the safety health condition of each main part of a bridge can be monitored in real time, any potential safety hazards about the fatigue of the bridge is early warned, the bridge can be timely maintained, and the problem about health monitoring of the bridge is relatively well solved.

Description

technical field [0001] The invention relates to the technical field of bridge health monitoring, and in particular to a bridge health monitoring system based on acoustic emission technology. Background technique [0002] In recent years, the country has invested heavily in infrastructure construction, and the construction of various types of bridges has been fully developed, such as highway bridges and high-speed railway bridges. However, accidents such as bridge collapses also emerge in endlessly, some are caused by human factors such as cutting corners, and some are caused by technical defects in bridge health inspection / monitoring. At present, there is no technology that can effectively detect / monitor bridge health problems and monitor the health status of bridges in real time. Therefore, how to design a system that can effectively monitor the health of bridges, so that when an accident occurs, an early warning can be generated, so as to avoid the occurrence of casualtie...
