SMART CAMPUS

 
In this project our aim is to implement the complete automation of our campus and making our campus smart. Here we trying to implement the four basic necessary needs of any campus and they are,

Secure money transfer system.
Intelligent information system.
Smart library management.
Student attendance and security system.

1)  Secure money transfer system
The main objective of this project is to make all the transaction in a campus without liquid cash. Students not need to keep cash  to purchase anything inside the campus ,they just need to swipe the card given to them . Then the sufficient amount is deducted from their account .They can use this facility for,
·       Canteen bill payment
·       Exam fee, fine, purchasing of books etc.
2)  Intelligent information system.

        The aim of this section is to develop an embedded system to make a smart display  system which displays the notice information when the authorized user send the notice message from his laptop or pc. This system is very useful in offices or colleges and information can be passed rapidly to all.

3)  Smart library management
        It actually provides solutions for library automations. By the proper implementation of this project we cannot need the librarian facility. We provide options for the following,
·       Auto text name and author name display
·       Taken date and renew date details
·       Theft identification of texts.

4)  Student attendance and security system.
        This option provides the attendance marking of students. We also provide option for the security of students.

AUTO SURVEILLANCE


                           Now a day, Building crashes are happening so frequently due to terrorism and natural imbalances like earthquakes. When such a disaster occurs, there is a probability for a human to get stuck in it. It's very tedious and dangerous for a person to enter into the affected area and monitor it. So we are developing a system to enter into that area which will monitor it.
                    
                        The system consists of two sections, ie, a controlling section and a vehicle part. The vehicle part is controlled from the controlling section with the help of wireless protocol called zigbee. The control section consists  of  a system from which the motion of vehicle is controlled . Basically four types of motions are incorporated.  The videos from the vehicle can be seen on the system placed in the control section. The communications between two sections is done using Zigbee protocol.

                      ZIGBEE MODULE is an IEEE 802.15 standard. It has a range of near 1 km and uses wireless communication. Generally they come in pairs and both of these are capable of transmitting and receiving data. It is connected to the PC through RS232 protocol. It is easy to use, requires minimal power and provides reliable delivery of critical data between devices.
                      
                    The vehicle part consists of a webcam through which the current status of the examined area can be viewed. The different angle of viewership can be obtained by rotating the vehicle. We also incorporated a sensor which will display the amount of temperature and detected the fire situation. All the monitored data’s are wirelessly transferred back to the monitoring station. So it is possible for an easy rescue.

Restaurant ordering System


Ordering is a major issue in every Restaurants. So inorder to help them we are introducing an embedded system which is capable of giving information about menu list in Restaurants.

In our project there are two sections.  An embedded  server and an embedded board in Tables in Restaurants. From Table we can request information about the Menu and check the availability of the order.We can avoid long waits at the cash counter by implementing this system.

           The  server will decode the informations send from the embedded board in the table and resend adequate informations. The embedded board  will again decode that information and will display on the LCD screen. So it’s a conveniant system for the customers.
