Sistema domótico de cierre de ventanas inteligente para la seguridad de menores de edad en guardería

Abstract

Through the thesis project developed for a home automation security system for windows based on Python, the aim is to determine the height and position of children between 3 and 5 years of age, through the use of a camera that will be located in the upper corner of the hallway near the window in question, thus achieving identity recognition according to their facial physiognomy and sending alerts through the Telegram platform, thereby achieving notification and prevention to each of the responsible teachers. of the different classrooms of a children's center; Throughout the field work, it was possible to demonstrate the correct functioning of the home automation system, reducing the accident rate in the daycare center to which the system was applied, since when children approach the window at a certain distance, they look at the warning sign. a LEGO police officer, which is reproduced on an 80 mm x 50 mm screen, which uses audio to alert with the name of the boy or girl who approaches it, thus distracting them and reducing the danger. With the use of closing and opening actuators such as: limit switch, magnetic sensor, motor with encoder, full control of the window was achieved so that it closes automatically during the issuance of the alert. The estimation of poses and height was achieved, thanks to a system called ALPHA POSE, which allowed the aforementioned variables to be determined effectively. As an additional advantage, the use of the Raspberry Pi 4 card was implemented to obtain better functioning of the home automation system. In order to avoid possible future failures, the Wifi communication protocol was also used for better communication between the home automation system and the teacher's cell phone and finally the distracting signal system of the LEGO police officer, the same one who calls, was used. children's attention and causes them to ignore approaching the window, while the teacher receives the alert and acts immediately to avoid the possible accident.
