A Port Crane Strain Measurement System Using Integrated Foil Gauge
Abstract— A strain measurement system is designed to realize real-time monitoring of port crane strain and
estimate the fatigue life of port crane. On the hardware side,the differential input of weak signal of ST350
strain sensor is realized by high-precision amplifier AD620, and the interference is filtered by two-stage filter.
On the software side, the strain measurement system is developed based on C#.The system can acquire data
and store it to the SQL Server database. 8-level load spectrum of port crane is compiled based on MATLAB
to estimate the fatigue life of port crane.The interface program is written by VB.net to transmit the acquired
data to the PI System. The PI System canstore the data andpublish the conditionof port crane to the web
page.The test results show that the performance of strain measurement system real-timeis good, the
accuracyof the integrated foil gauge is good, the fatigue life of port crane can be effectively estimated.
