Internet of Things-based health monitoring and security prewarning system of crane metal structure

Abstract

The invention discloses an Internet of Things-based health monitoring and security prewarning system of a crane metal structure. The Internet of Things-based health monitoring and security prewarning system comprises an Internet of Things sensing layer, an Internet of Things network layer and an Internet of Things application layer, wherein the Internet of Things sensing layer is used for acquiring an optical signal of a crane metal structure health parameter, demodulating the optical signal into an electric signal, compressing and packaging the sensing data electric signal and transmitting the compressed and packaged sensing data electric signal to the Internet of Things network layer; the Internet of Things network layer is used for receiving electric signal data, identifying the electric signal and sending identified data to the Internet of Things application layer; and the Internet of Things application layer is used for calculating the received data and judging that whether a warning signal is sent or not. The Internet of Things-based health monitoring and security prewarning system is capable of carrying out full-life circle real-time health monitoring and security prewarning on the heavy crane metal structure in an all-weather manner on the basis of an Internet of Things network, and has the characteristics of no electromagnetic interference, high precision, large measuring range, high reliability, long service life and the like.

Description

technical field [0001] The invention relates to the Internet of Things technology and the metal structure health monitoring technology of large cranes, in particular to a crane metal structure health monitoring and safety early warning system based on the Internet of Things. Background technique [0002] Hoisting machinery is the "backbone" of the production links of major industrial enterprises, but the situation and challenges facing the safety of large-scale hoisting machinery are very severe, and serious accidents still occur from time to time. With the rapid increase in the number of cranes in our country, the number of accidents has ranked first among all kinds of special equipment accidents for five consecutive years; On the one hand, the responsibility is heavier and the pressure is greater. Therefore, it is imperative to study crane safety early warning technology. At present, the domestic safety assurance for hoisting machinery is still based on the "regular main...

AI Technical Summary

Problems solved by technology

At present, the domestic safety assurance for hoisting machinery is still based on the "regular maintenance and after-the-fact maintenance" of the maintenance unit and the 2-year periodical inspection of the quality inspection department. Take more targeted and effective measures for the safety of large cranes to prevent various public safety accidents. Therefore, it is urgent to propose a targeted measure to prevent such accidents and ensure the health of the crane structure. Monitoring and safety early warning technology will emerge
