Implementación de una red CAN con conectividad a dispositivos IoT como solución de interconexión desde una plataforma abierta

Abstract

The present project developed is a solution to the need to connect devices with modern IoT technology in limited networks. The project aims to implement a CAN network with connectivity to IoT devices as an interconnection solution from an open platform, making it possible to manipulate its actuators and monitor sensors. A prototype was developed based on electronic devices that were previously analyzed using comparative matrices, and that helped to choose the components that were adapted to the needs and characteristics of this prototype. Several analyses were carried out to obtain an effective design in CAN connectivity, IoT devices and open platform. CAN communication was carried out using PIC microcontrollers, and data sent to the Thinger.io platform was carried out using a NodeMCU. In addition, an oscilloscope was used, which allowed for observations of the behavior of electrical signals, and for the connectivity analysis, the PRTG monitoring tool was used. In conclusion, for the evaluation of results, the effectiveness of the system and the application was verified, using established indicators, from which a 99.09% effectiveness in its operation was obtained as a result. The developed design is a low-cost solution.
