A Simple Instrumentation System for Large Structure Vibration Monitoring
Abstract: A conventional
instrumentation systems in monitoring vibration of large-scale infrastructure
building such as bridges, railway, and others structural building, generally
has a complex design. Makes it simple would be very useful both in terms of
low-cost and easy maintenance. To make system become simple, low cost, and easy
in maintenance, this paper proposes a distributed network for implementation
system. The system consists of field bus topology, using single-master
multi-slave architecture. Master is a control unit, built based on a PC
equipped with RS-485 interface. Slave is a sensing unit; each slave is built by
integrating a 3-axis vibration sensor within a microcontroller based data
acquisition system. Vibration sensor is designed using the main components of a
MEMS accelerometer. The software is developed for two functions; a control
system hardware and a data processing. To verify performance of the developed
instrumentation system, several laboratory tests have been performed. The
result shows that the system has good performance.
