Implementación de un dispositivo móvil para el trazado y perfilación de rutas ciclísticas usando un altímetro y GPS para la promoción turística en la provincia de Chimborazo.

Abstract

In the present work, it was implemented a mobile device for the tracing and profiling of Cycling routes to carry out such tourist promotion in the province of Chimborazo. The NEO 6M GPS module was used as the basis for geolocation and the BME280 sensor for altitude measurement from barometric pressure, while for data processing the STM32F103C8T6 microcontroller was used. The device displays the measured values in an OLED screen, which are stored by means of buttons on a micro SD memory card in CSV format. The stored data was later imported into the database of the website: cicloturismochimborazo.com, which is in charge of presenting the technical and tourist information on cycling routes. The website was designed with the help of WordPress platform. From the tests carried out, it was obtained that the geopositioning system presents an average error of up to 4.5m and the altimetry system presents a maximum relative error of 0.30%. It was also determined that altitude measurements are affected by the variation of the reference atmospheric pressure and altitude gain. The device has of 21 hours of autonomy, an average recharge time of 4.35 hours and a total weight of 168 g. It was concluded that the device works properly and serves as a reliable tool for position and altitude recording of cycle routes. It meets autonomy requirements together with the visualization of the results on the website. In addition, it is a low-cost device compared to similar devices and displays a good cost-benefit ratio. It is recommended to analyze the possibility of increasing the autonomy time and reducing the size of the device.
