32 Safety Monitoring System for Crane Structure Based on Optical Fiber Sensor
Download citation file:
Established the stress on-line monitoring system of quayside container crane structure. Signal acquisition of the system used the fiber bragg grating sensors. Sensors in four parts of the crane were connected in series, and each part include 12 sensors. After the demodulated and analyzed of the sensor signals, monitoring results were displayed in the driver room and monitoring center on the ground. Every monitoring system was connected through LAN. This system realizes the online, continuous monitoring of the quayside container crane structures and provides the services of monitoring information query, remote management, situation assessment and warning forecast of crane metal...
