voice operated intelligent lift or elevator
Abstract
The main aim of this project is to design and construct a voice operated lift/elevator control system. This system acts as human-machine communication system. Speech recognition is the process of recognizing the spoken words to take the necessary actions accordingly. User can also control the electrical devices like fan, door etc with the help of voice recognition system. This device is very helpful for paralysis, short height people and physically challenged persons. The speech recognition system provides the communication mechanism between the user and the microcontroller based lift control mechanism. This project makes use of a DC motor for moving the lift/elevator based on the voice/speech commands given by the user and voice recognition chip is used for recognition of the voice commands. Microcontroller is programmed, with the help of embedded C instructions. The
microcontroller is capable of communicating with all input and output modules. The voice recognition system which is the input module to the microcontroller takes the voice instructions given by the user as input and the controller judges whether the instruction is to lift upwards or to the downwards , and according to the users voice the switching mechanism controls the lift. The similar voice based commands also used to turn on/off
the fan inside the lift. Also, LCD display is available for visual information of operations being performed.
Project Abstract / Summary : Now-a-days we can find huge no of apartments crowded in nearby area with multi storage building capacity. The apartment consist of several floors. This project better suits for all, mainly for physically challenged people. To move from one floor to another we generally used staircase or lift which is normally operated by using switches. The main purpose of this project is to operate the lift by using voice command.
