Software de gerenciamento, armazenamento, processamento e visualização de dados em tempo real para aplicação no sistema telemétrico raibee

Abstract

This project aims to develop software for the RailBee® telemetric system based on the monitoring of city trains using wireless sensor network mechanisms and embedded systems. This software receives and displays, in real time, variable data for actual train speed, traction motor current, brake application, train suspension airbag pressure, cab condition (forward or reverse) and indication of doors (open or closed). The telemetric system has an innovative nature and is composed of four subsystems: a device embedded in the vehicle capturing the train’s information (mobile station), a repeater (router station) of radio frequency (RF), an RF signal converter Ethernet (base station) and a software for processing, storing and displaying data (central station). The main activities of the central station software are to process train data, display it to its Operational Control Center (CCO) users and store it in a database for future research. To achieve its objectives, the project is modeled by a microservice architecture and messaging broker system, in addition to allowing the competitor to run through multithreaded and a reactive user interface using websockets. The system maintains multiple simultaneous connections to embedded devices to receive train data packets. These packages are handled, stored in the database, and forwarded to storage queues, where the destination is a web application that displays train information to users. This real-time monitoring and archiving of this information enables analysis and reporting, improving the quality of service provided by the public transit company.
