Research of Structural Health Monitoring System for the Crane Based on Wireless Strain Sensors

Abstract

Research on the field of crane health monitoring has been conducted for the strain monitoring demand on the using of key components of crane and major safety monitoring requirements of crane in China. Strain monitoring nodes based on wireless transmission network have been designed, and crane structure health monitoring system has also been developed on the basis of this technology. The system has been taken contrast experiments with strain gauge acquisition equipment on-site, and the results of experiments show that this system could not only measure accurate strain, but also realize the real-time monitoring and reflect the stress state of crane on operation in time.
