Designing an Ardunio-microprocessor-and-Labview-based system for monitoring wave spread in the ground caused by constructing activities

摘要

There are many activities such as embankment vibratory rollers, piling, blasting tunnel ... causing wave spread in the ground that affect the surrounding buildings. The high ground wave may damage the surrounding buildings and hence may cause confrontations between the local resident community and the project owners. To determine the radius of vibration of each vibrating source that can damage the neighbouring buildings as the basis for planning, choosing construction technology, and designing damping methods to minimize the risk to the surrounding buildings, It is necessary to measure experimental vibration in the field. This paper describes how to install the Ardunio-circuit-based vibration measuring system , by using labview and shows some experimental results of measuring vibration transmitted to the ground caused by constructing activities in Da Nang, Vietnam. The results prove that the measuring system has a considerably low cost and meets the standards and precision according to Vietnamese ISO 7378 and DIN 4054. The software written on Labview platform is connected to the hardware to collect vibration signals from sensors, analyse measurement data, and then make reports on measurement results in table or chart formats to meet the current standard vibration measuring requirements.
