Desarrollo de laboratorio remoto virtual para secuencias de cilindros hidráulicos de un banco de pruebas en el laboratorio de neumática y oleohidráulica de la Facultad de Mecánica.

Abstract

The purpose of this work was to develop a virtual remote laboratory (LRV) for hydraulic cylinder sequences in the pneumatics and oleohydraulics laboratory of the Faculty of Mechanics at ESPOCH, in order to improve the cognitive and practical learning of students of the subject. For this, the analysis and diagnosis of the existing test bench was carried out, determining the operating status, and obtaining the improvement parameters to solve the technological requirements of an LRV. Then, we proceeded to the development of the control circuit formed by: a Router to which a fixed IP was assigned and then a public IP for web access from any point, a camera for remote access, an HMI screen for the manipulation of local mode in the laboratory, a PLC (Programmable Logic Controller) that controls and automates the hydraulic system and a Raspberry Pi that fulfills the function of web server as well as data storage. A virtual platform was designed that allows the teacher to register the students and create practices; It allows students to schedule schedules to later carry out the practice in real time and be able to visualize it. To validate the work, performance tests and a conformity survey of students of the Faculty of Mechanics were carried out, where each one carried out different sequences requested in the laboratory guide without presenting any eventualities, in addition, the learning could be evaluated in the laboratory reports presented. Favorable results were achieved by achieving the objectives in the LRV proposal concluding that this type of project is feasible to condition other test benches. It is recommended to check the electrical and internet connections before operating the equipment and use the user and maintenance manuals to avoid damage.
