Modular design of the Digital Control and Measurement System of a Falling Weight Deflectometer

Due to the devices required for deflection bowl based analysis, the timing of the processes is key as is how versatile and robust the control system must be for use on road sections. This document presents the methodology followed to create a control device that meets certain requirements for the tests considering the synchrony of the electro valves control, geophones sampling window, analog signal conditioning and digital processing, allowing the possibility of maintenance on field making it reliable, robust and easy to implement, especially in countries with limitations in the manufacture of electronic devices. The experimental results are presented with the help of a Python-based HMI.
