ACTIVE KIOSK WITH SPEECH:
This project is an excellent tool for automatic information access & reference. The project is designed to Display the Messages like Tourist Information / Bus Timings etc. Here the highlight of the project is its ease of use & flexibility. The project also associated with a set of Voice Chips, so as to speech & conveys the pre-stored information about a Tourist Place or Bus Timings.
For example, when the project is used for Tourism purpose, the project is made to display the information about a tourist spot just by touching on the map. When a particular spot is touched, the project displays information like Distance, Bus Fare, timings etc.
The project can be customised to automatically provide all relevant information about Bust Timings, Product Info, Services etc.,
The project based on Microcontroller 89C51 (which is an Intel Architecture based chip) Micro-controller Based Displays are widely used where precision and accurate reading should be read on some sort of display unit.
Micro-controller Based Display Units have been with us since the early eighties and their significance has grown enormously over the past few years. They are used as display mechanisms in clocks and other pointer-based instruments, in industrial instruments where field reading should be adjusted, various testing & measuring tools and, of course, in commercial hand held gadgets.
METHODOLOGY:
This ACTIVE KIOSK WITH SPEECH system is just a starting point for exploration of Micro-controller chips. Hence it has few hardware parts with supporting software, which is inherited inside the memory of Micro-controller chip. One Key Pad is connected to Input Port of Mother Board, which contains Micro-controller chip, and output is taken across Output Port and connected to 7 Segment Display Board.
The data is to be sent to the 89C51Micro-controller chip by pressing keys on Key Pad as Input Data. The 89C51 Micro-controller chip receives this data at its Input port and manipulates it with the help of software and send the final output to Output Port. The 7 Segment Display board connected to this Output Board displays that data as visual representation of the key press action.
MAIN FEATURES OF THE PROJECT:
1. Versatile System for Information Display.
2. Low power consumption, and compact size,
3. High Useful for Blinds due to the Voice Capability,
4. Greater control range due the usage of re-programmable memory banks.
BLOCK DIAGRAM:
This ˜89C51 WITH LCD DISPLAY™ project is constructed around the smart and self-efficient Micro-controller chip.
Let us see each sub-blocks description in separate heading.
KEYPAD: This stage helps user to set the data [i.e., User Data] for display purpose. There are 0 to 9 numbered keys, which are used to set the User Data.
89C51 MICRO-CONTROLLER: The 89C51 Micro-controller is heart of this project. It is the chip that processes the User Data and executes the same. The software inherited in this chip manipulates the User Data and gives out the respective result to Display Unit.
7 SEGMENT DISPLAY: This module provides the visual presentation of the entered User Data for the user benefit. This module receives its information from Micro-controller, and not from the Keypad.
POWER SUPPLY UNIT: This unit supplies the regulated, constant working voltage to this system.
