Diseño e implementación de un sistema IOT para pagos y control de acceso vehicular mediante la tecnología NFC para mejorar el tránsito en la EP-EMMPA.

Abstract

The objective of this work was to design and implement an Internet of Things (IoT) system for payments and vehicle access control using Near Field Communication (NFC) technology to improve traffic in the Municipal Public Company Mercado de Productores Agrícolas. San Pedro de Riobamba (EP-EMMPA), for which the state of the art of technologies was studied. When analyzing the current access control system to the establishment, traditional technologies were appreciated, without taking into account the user experience, generating vehicular congestion at the exit of the place; Thus, an IoT infrastructure was analyzed together with NFC that allows access to and exit from the place to be controlled autonomously and efficiently, allowing to alleviate the traffic problem; Thus, a prototype was designed with HTTP and MQTT as communication protocols, and cloud computing, which allowed data management remotely, through the design of a mobile application, the Google vision API with the development of a script in Python, which allowed the recognition of the vehicle license plate as an authentication method. For the analysis of the latency, the response time of the server, the delay of the API and the MQTT protocol were taken into account, resulting in 3693 msec at the entrance and 1640 msec at the exit, which in comparison with the current system would be considered very Well, the implemented and tested authentication methods generate a high degree of security against possible attempts to violate the system. It is concluded that the prototype reduced user waiting times by 80% compared to the current system, and has efficient security mechanisms that would allow a large-scale implementation of access control to the establishment. It is recommended to contract the hosting service with greater capacities according to the traffic that is going to be generated.
