Diseño e implementación de un prototipo de control domótico de bajo costo activado por voz para personas con discapacidad motriz.

Abstract

A prototype of low cost control home automation activated by voice to people with motor disability was designed and implemented in the present degree work. It allows controlling the actuators placed in the different environments of a home model such as bathroom, dining room, bedroom and living room through a web application that receives voice commands, converts them to text, compares them with previously established orders and controls events such as on-off lights, opening-closing door and window, on-off the fan or heater. The power to the actuators are 3.5 V to the LED diodes that simulate the lights and 9 V to the fan or heater. The web application was developed with natural language for turning on and off the actuators in the different home environments. The system works under a local network with internet access, both the actuators and the web application work through an Apache web server set on the Rasberry Pi development card model 3B. The web application was developed under the programming languages html, javascript, php and Python. The actuators that control the events of the lights are assisted by a circuit power elevator, implemented and connected to the various GPIO ports of the Raspberry Pi. The response time of all the actuators in the different tests carried out and in the time interval of one hour for 10 hours was optimal because they did not suffer significant changes. The prototype is of great help for people with some motor disability because their control depends mostly on the voice avoiding the limited movement that these people have. It is advisable to use the Google Chrome browser to the web application because it presents the best features to its correct functioning. KEY
