Proposal for an automation system of digital levels

This paper presents the methodology, results and conclusions of the development of an Automation System for Digital Levels - SAND, consisting of a platform that houses the stepper motor and gear systems. This platform is controlled by a microcontroller board, which allow the horizontal movement of digital topographic level, without interference from the observer. Furthermore, this platform also accommodates the engine that is used to perform the focusing of the image, in this case the vertical sights that are installed with the object you want to perform the monitoring. By employing techniques of leveling, the SAND performs readings of sight with bar codes, to determine the gaps between the points of interest, and thereby determine possible shifts in the structure. The system was developed to carry out the monitoring of structures such as bridges, viaducts, dams, buildings, real time, automatically, ie without the need for a Technician to operate the level. The results demonstrate the feasibility of the proposed methodology.
