Construcción de un módulo electrónico de reconocimiento facial para un sistema domótico basado en protocolo de comunicación X10.

Abstract

The objective of this degree work was the construction of an electronic module of facial recognition for a home automation system based on the X10 communication protocol for access control, cascade classifiers were used for this purpose. In the detection of face, the LBPH algorithm (Local Binary Pattern Histograms) was used. Fort he communication of CM15A transceiver module and AM466, plug- in transceiver module, with the Raspberry pi 4, controller card, the installation of special libraries such as libusb1. 0.0, mochad and X10, was carried out, which allowed the bits of information to be transmitted through the power line. The variables considered were distance and change of lighting at different times of the day, under these parameters it was possible to determine that the algorithm achieved to detect, perform recognition, and allow access, resulting in efficiency of 95%. It is concluded that use of the X10 protocol represents a great advantage compared to other communication protocols thanks to the fact that it does not require additional wiring to send and receive data bits. When using the X10 protocol, it is recommended to have an external power backup system, to prevent unforeseen failures in the access control system due to power outage.
