Wireless Data Acquisition from Bridge Monitoring
Baoshun Liu · 2015
This paper introduces composition of a system platform to collect data from a wireless monitoring bridge, develops software to receive data from monitoring bridge fixed with vibration sensors and temperature sensors.We use INV3020 made by Coinv(China Orient Institute of Noise & Vibration) as a lower-position machine.Communication protocols between INV3020 and upper-position machines have been defined during data acquisition of INV3020 and computers in a laboratory.Developed software with C sharp in the upper-position machine by the communication protocols enables to decode vibration and temperature signals collected by INV3020 and save them into database created by SQL Server.The upper-position machine can also control some actions of INV3020 regarding how to collect data and when to send time-domain waveform.3D GIS is used to show locations and status of sensors.There is a model library in the upper-position machine that can set limen to judge if the bridge works well.Research shows that INV3020 is an excellent product to monitor bridges, our developed software is a good try to receive data from monitoring bridge.
