Incubadora avícola electrónica semiindustrial con monitoreo remoto de las condiciones de incubación a partir de Tecnología LoRa

Abstract

This research project describes the development of a semi-industrial poultry incubator with remote monitoring based on LoRa technology. The equipment was implemented with a maximum capacity of 352 hen eggs, and optimizes processes performed by operators or supervisors. The equipment is based on a LPWAN network and uses LoRa technology for wireless communication. The final node is controlled by a PLC controllino, which has connected sensors that send the temperature, humidity, and air quality signals inside the incubation chamber. Through programming, the system ensures the right conditions for the egg to hatch a new life. The temperature control is based on a 5v PID control that through a conditioning circuit supports an AC load up to 1500 watts and allows setting a specific temperature, humidity and air quality control is based on ON/OFF sentences. The data collected by the sensors are sent by SPI communication to the LoRa transmitter that modulates this information and sends it to the Gateway which is responsible for receiving the data from the end nodes and send all this information to the server that is hosted in a virtual machine in Microsoft Azure, so that they are subsequently stored in a MySQL table. Data is visualized through a graphical interface with the grafana tool allowing constant real-time monitoring of the magnitudes involved in the incubation process. Data is recorded in a table but data out of normal conditions range are stored in another table. Inappropriate conditions of the system are notified via telegram messages. The equipment was tested for 22 uninterrupted days, although the hatching cycle of chicken eggs is 21 days due to different biological factors of each egg, this time can increase up to 48 hours, in the test period hatchability was verified with stable Conditions to meet the requirements of the embryos.
