Prototipo para el sistema de notificación de llegada de buses y aviso de paradas para personas con discapacidad visual

Abstract

The prototype designed and implemented provides assistance to people with visual disabilities at the moment to take the bus route and get off at the bus stop desired using an Android application. At first, the blind population that living in Quito DM is detailed. Features, operation and transmission technologies supported by each device used in the prototype (HC-05 module and nRF24L01 transceiver coupled in an Arduino UNO) is also presented. Android operating system and software used for application development is also described. The design and development of software includes the Android application configuration in which an algorithm compares the signals emitted by buses and bus stops, allowing announce the arrival of the chosen route and bus stops. In programming the Arduino UNO located on buses and bus stops is established the communication type and the signal to be transmitted. Finally through performance tests is specifed the power and speed of transmission of nRF24L01 transceivers. In addition, electric current consumption tests are made.
