Microcontroller Based Low Cost Seismic Vibration Generating System

Studying and analysing earthquake signals, in some depth, is an important aspect of engineering, geophysics, and disaster management. At present seismic vibration analysis involves large-scale setups that require a considerable investment. Shake tables, underwater explosions, colliding large masses with shock absorbers, are all expensive, complex, and non-mobile processes of generating seismic vibrations. In the backdrop of the above, the purpose of the present study is rather modest, viz. to examine and suggest a viable and reliable low-cost technology with a portable method for producing seismic vibrations and foreshocks. To achieve the objective, a novel algorithm is devised, tested, and implemented employing a synchro, stepper motor, and microcontroller. The results were verified by using a technique that uses changes in the rotating magnetic field to measure velocity with high accuracy. The findings from the aforesaid method are quite accurate in comparison to the reference data. The analysis of the measurements performed in the frequency domain with MATLAB is in good concurrence with the benchmarked data. The present study provides an alternative and more economical method to analyse shockwaves and any seismic activity that takes place in the surrounding areas.
