Diseño y simulación del sistema de adquisición de datos y tracking del proceso productivo del café: diseño y simulación del sistema de adquisición de datos basado en iot con lorawan para el proceso de tostado del café.

Abstract

The following document simulates the communication protocol, on-off control of a roaster and simulation of data visualization through an IoT platform for the coffee roasting process that is carried out in the Santa Elena Demonstration Farm located in the province of Pichincha, for this the necessary theory about the coffee roasting process and the communication architecture of LoRaWAN through Lora radiofrequency communication is determined, and the definition and use of IoT to determine the platform that allows visualizing the data through MQTT communication thus contracting a monitoring, data acquisition, collection and storage structure because the temperature information and its variation in the roasting process allow to represent a roasting curve that is very important to keep a record of roasting and determine the different levels of roasting of coffee in order to achieve an aroma and flavor according to the tastes of the consumer In addition, the detailed engineering necessary to implement this protocol is presented, taking into account the characteristics of the machine, its location and distance from the place where the Gateway would be located, which allows receiving the data and sending it to the LoRaWAN platform and through simulation. It is analyzed if it is appropriate to use this communication protocol through several parameters that must be taken into account when sending and receiving data.
