Research on Fault Monitoring Device of Highway Bridge Expansion Joint Based on Internet of Things Technology

Among various large-scale engineering structures, highway bridge structures are characterized by a large number, long service period, and huge investment. Therefore, any construction quality, safety accidents, natural disasters or structural aging, insufficient bearing capacity, etc. may cause the bridge as a whole or Natural cumulative damage and accidental damage occurred in expansion joints of highway bridges, which affected the safety of bridge operation. Therefore, a research on a fault monitoring device for highway bridge expansion joints based on the Internet of Things technology is proposed. Design the fault signal acquisition equipment of the Internet of Things technology, first analyze the basic characteristics of the road bridge expansion joint fault, design a signal collector based on the Internet of Things technology, and design a signal extractor based on the Internet of Things technology. Design a data acquisition card for the failure monitoring of highway bridge expansion joints. Finally, through example analysis, it is proved that the detection accuracy of the highway bridge expansion joint failure monitoring device combined with the Internet of Things technology is very high, and the fault monitoring accuracy is good, which meets the basic requirements of highway bridge expansion joint failure monitoring.
