Implementación de un prototipo de visualización digital inalámbrica mediante un Head Mounted Display Monocular para un voltímetro/amperímetro de corriente directa.

Abstract

The objective of the present work was to implement a prototype of digital wireless visualization by means of a Monocular Head Mounted Display (HDM) for a direct current voltmeter / ammeter, being the same a prototype of easy handling and interpretation of measurements in the electrical magnitudes. and current. The prototype called SeeLab.1 consists of four stages, related to each other allowing the measurement and sending of data through a wireless communication. The first stage is responsible for measuring voltage in a range since 0 to 120 V in direct current (DC), which after a process of signal conditioning is treated in an Arduino development card. The second stage, consists of the ammeter with the ability to measure current in a range of 0 to 3 amperes (A) in DC, in the same way as we worked with the voltmeter, the signal is conditioned and processed in the same development card. The third stage, consists of wireless communication through bluetooth technology, which normally works for the required distance. The fourth and final stage consists of the printing of the values in the monocular HMD by means of a process of reflection and refraction of light. Each magnitude that the device is capable of measuring was analyzed using ISO 17025 using the repeatability technique with which values less than 10% were found, showing that the device is stable in measurements. It is recommended to realize a mobile system in the HMD that helps in the improvement of the projected image approach, making an adjustable system for the perception of users with other visual problems.
