1 Project Description
Hewlett-Packard has developed a new type of accelerometer. The new accelerometer allows for good dynamic range and very precise measurement of acceleration. The purpose of this project is to develop an example product for Hewlett-Packard that demonstrates the commercial application of the new accelerometer. The example product is a device that senses vibrations in a structure and displays the vibration data in a human-readable format through a web-accessible interface. This device will be temporarily installed on the Van Buren bridge in Corvallis, Oregon to monitor stress, strain and motion across that bridge.
The development of specialized sensors to detect wear in large structures has led to a new engineering discipline called Structural Health Monitoring (SHM). Civil Engineers use SHM systems to evaluate the integrity of structures and schedule preventative maintenance. Real-time accurate SHM is essential to improving the lifetime and safety of critical infrastructure.
This project will utilize six accelerometer devices placed evenly across the bridge to extract vibration data. One device will collect and process information from all six sensors and output a single data stream to a remote server. The data will be stored in a database on the server, where it can be displayed in an organized and cohesive fashion in real time with a web browser.
The devices will be compact, weatherproof, and battery powered.
The electrical engineering students will focus on system design, circuit board design and layout, and integration of sensors and interface electronics. The computer science students will work on remote web host platform development.
The sensor network and online monitoring functionality will make it easy for engineers to monitor structural health of bridges by allowing them to observe how the structure responds to the movement of vehicles across it.
