Smart Elevator Panel Using Voice Recognition System

Product Introduction:

Using artificial intelligence in voice recognition, this panel allows the user to move to different floors by calling the desired floor without pressing the elevator buttons. People with disabilities or children will be able to use the elevator easily by using this system.

This system has been implemented in 10 common languages of the world and the Persian language. The desired technology is one of the leading and practical technologies in the elevator industry. The design and fabrication of the inside and outside cabin panels are equipped with a Farsi voice processing machine, the ability to process multiple languages at the same time, removing noise and extra sounds, periodic updates, compatibility with old cabins, online and local voice processing for when the Internet is down.

Technical Specifications:

The final product is technically divided into two parts, inside and outside cabin panels, whose technical specifications differ.

* Key panel of outside cabin:

* one Arduino Microcontroller based on AVR ATmega328 to check the status of sensors and make appropriate decisions

* two potentiometers (10K ohm) to adjust sensitivity and calibrate

* 12 resistors (330 Ohm) to adjust sensitivity and calibrate

* one infrared receiver to receive commands from the user

* four infrared transmitters to receive commands from the user

* 4 Green LEDs to show sensor activity

* 4 Red LEDs to show sensor activity

* two capacitors (100nF) to adjust sensitivity and calibrate

* one capacitor (100uF) to adjust sensitivity and calibrate

* Key panel of inside cabin:

* one Raspberry Pi Element 14 Raspberry Pi 4 Model B is responsible for data processing and analysis.

* one condenser microphone: to connect to the Raspberry Pi to receive the user‘s voice

* 1 USB Type C power adapter to power Raspberry Pi

* 1 Micro SD 32GB class 10 memory card to boot the operating system and save data on the Raspberry Pi

* one 7-inch TFT touch screen to display Raspberry Pi images. This screen is not useful for elevator users and is only used for installation technicians.

* one mouse and one keyboard for technicians to access the Raspberry Pi and perform activities such as updating

Advantages:

* Preventing the spread of diseases caused by hand contact with an infected object

* Fixed the problem of placement of elevator keys for skyscrapers and tall buildings

* Easy to use for children and people with physical disabilities

* Affordable price
