In this present world day by power usage is increasing, but power sources are not increasing to generate enough power for our needs. So it is compulsory for everyone to eliminate power waste methods. One of power wasting applications is present street light control system, in this many times the operator forgets to switch off the lights even after morning also and we do not have the option to switch on only a few lights at midnights as density of people is less at that time. And in the present system we need lots of manpower. We can eliminate this power wastage and reduce manpower with latest technologies that are coming out today.
Especially in mobile field so many applications are being developed to give us more information and entertainment. This project is designed with a combination of two latest and most demanding technologies that are Smart phone and Embedded Systems
A Smart phone is a mobile phone built on a mobile operating system, with more advanced computing capability and connectivity than a feature phone The first smart phones combined the functions of a personal digital assistant (PDA) with a mobile phone. Later models added the functionality of portable media players, low-end compact cameras, pocket, and GPS navigation units to form one multi-use device. Many modern Smartphone’s also include high-resolution touch screens and web browsers that display standard web pages as well as mobile-optimized sites. High-speed data access is provided by Wi-Fi and Broadband.
With present, phones like smart phones, we can browse everything from mobile itself.
.In this project we will create an application to control street lights from the webpage. This web page can be opened from anywhere using mobile or computer. On this web page we have some options or buttons to control the street lights, whenever we operate this application, then it sends commands to control system through internet links
At controlling system side we have Ethernet module, micro controller and load controlling circuits. Whenever this Ethernet module receives command from its web application then it transfers this command to micro controller. Micro controller will control the respective loads depends upon the command it received
This is very safe and secure and also we can control many loads without getting confused by adding names or images in the application. We can also control many streets from single applications by providing data into servers.
KEIL IDE for developing micro controller code
