Implementación de un prototipo dosificador de alimento granulado para mascotas programable y controlado local y remotamente basado en las tecnologías GSM e IoT.

Abstract

The present work describes the implementation of a granulated food dispenser prototype with the purpose of contributing with pet caregivers. The development of the prototype began with the literature review on the architecture of the dispenser and the existing mechanism, for the dosage of granulated food. The modeling of the dispenser and the validation of its design were carried out in Solid Works 2018, through a static analysis it was determined that there is no danger of ruptures and deformations in the parts of the dispenser exposed to stress. It was determined through tests that the electromechanics allows a dosage of 12 grams per second, by filling the granulated food storage to the capacity of 800 grams and causing its total emptying it offers a maximum efficiency of 100%. Additionally, a water dosing system was incorporated based on a mini pump that provides a dosage of 21 milliliters per second. With the use of Python and its OpenCV library, a dog breed recognition system was code to define the amount of food that should be dosed. A local graphical interface as implement in which the desired amount of food and water can be varied and the dosage schedule can be programmed. In addition, the dispenser can be remotely monitored through the Ubidots IoT platform with efficiency of 97.7% and generate alerts signals of low feed and waters levels through GSM text messages and email. The opening to the improvement of the prototype is provided through the insertion of resources to generate a totally autonomous system and new functionalities to include medicines and vitamins.
