Diseño de un nodo LoRa-GPS para localización de bicicletas implementado en una red LoRaWAN

Abstract

In this degree project, a tracking device was developed to be implemented in a bicycle and thus add an additional level of security, using the theoretical and practical concepts of IoT, cloud computing and electronic design. In order to successfully achieve the stated objectives, it was proposed to work in several stages. Initially, it was necessary to identify the need and the problem and from this to seek and propose a practical solution for most people who have a bicycle as a means of transportation. The objectives and methodological design were established, the selection of the technologies to be used was made, selecting different devices that best fit the solution.

A test environment was implemented based on LoRa technology developed with a gateway, a commercial test device and a web page developed in Angular for the visualization of the data obtained. The design and construction of the final device with its own metrics and design was carried out, to meet the main objective of the project, but at the same time it can be mimicked on the bicycle. The connection was established between the embedded system and the gateway, which are responsible for processing and sending the data to the cloud, in this case the server chosen was ThingSpeak, and finally the correct operation of the web application that allows viewing the data stored in the cloud was verified.

The final results showed that the system presents a response according to the objectives set, since it was successfully developed a tracking device for bicycles with an accuracy and range similar to that provided by a commercial LoRa-GPS node, but with the advantage that the developed device is much smaller and easier to mimic and integrate into a bicycle. In addition, a web application was designed to visualize the different coordinates obtained by the device and sent to the server through a secure encrypted data communication.
