Abstract
Este Proyecto Fin de Carrera titulado “Desarrollo de Prototipo de Diana para el Guiado de una Tuneladora” implica el diseño y construcción de un modelo de diana que permita mejorar en alcance, precisión y tiempo los actuales modelos disponibles para el control y cálculo de la trayectoria de una máquina tuneladora durante el proceso de perforación. Esta diana dispone de dos paneles, uno translúcido y otro opaco, diseñados para permitir la incidencia de un haz de láser. Para mejorar el sistema, se utiliza un láser de color verde en sustitución a los actuales láseres de color rojo, el cual tiene un alcance efectivo de 200 metros frente a los 100 metros de los de color rojo. Para la detección del láser al incidir en los paneles de la diana, se utilizan dos cámaras que permiten obtener las imágenes a partir de las cuales se calcularán las posiciones de incidencia del láser, con lo que se obtendrán las desviaciones y ángulos que se producen en la máquina. Además, se requiere usar un inclinómetro que calcule el ángulo de giro en el eje de avance, puesto que no es visible para la diana. Todo esto ha requerido del desarrollo de un software en el entorno de programación Matlab, que controla todos los dispositivos hardware y calcula la posición en un sistema de referencia global de la máquina tuneladora. Además, para el control del inclinómetro, se ha desarrollado un software en lenguaje C por medio del software MPlabIDE. Por último, en este proyecto se ha desarrollado un método de comunicación con una interfaz gráfica de usuario (GUI) que permite la visualización de la trayectoria calculada en este proyecto, con el fin de conseguir una fácil interpretación por parte del operario que controla la tuneladora de los cálculos obtenidos. ____________________________________________________
The Final Project called “Developing a Target Prototype for a TBM or Tunnel Boring Machine (TBM) Guide” involves designing and building a type of target that improves the range, accuracy and time of the currently available models used to monitor and calculate a TBM´s journey during the drilling process. This target has two panels, one is translucent and the other one is opaque, they are designed to produce a laser beam. It uses a green coloured laser instead of the red lasers which are currently used to improve the system which has an effective range of 200 metres compared to that of the red laser range of 100 metres. Two cameras are used to detect the laser when it shines on the target’s panels. They take pictures that are used to calculate the position of the laser beam incidence, from which the deflections and angles produced in the machine are then calculated. An inclinometer is also needed to calculate the pivoting angle in the axis of advance as the target cannot detect it. Matlab development environment software is required to monitor all the hardware devices and calculate the position in the TBM´s whole reference system. C language software has also been developed using the MPlabIDE software to monitor the inclinometer. Finally, communication is established in this project using a graphical user interface (GUI) which allows the calculated journey to be displayed so that the operator controlling the TBM can easily understand the calculations obtained.
