Internet based advanced street light controlling system
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 option to switch on only few lights at mid nights as density of people is less at that time. And in present system we need lot of man power. We can eliminate this power wastage and reduce man power with latest technologies that are coming out today.
Now a day’s so many useful technologies are coming out to make our life style more comfort, luxurious and secure. Especially internet technology brings up many applications and advantages for present and future generations. Present world mostly is being controlled by internet. Previously internet is limited to only computers but because of the advancement in technology especially in mobile communication, now internet is completely being accessed by latest phones like Smart phones
In this project we will create an application to control street lights from webpage. This web page can be opened from anywhere using mobile or computer. In this web page we have some options or buttons to control the street lights, whenever we operate this application then it sends command to controlling system through internet link. At controlling system side we have Ethernet module, micro controllers, Zigbee transceivers 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. Using Zigbee we can control different streets from single Ethernet module by transferring command from one controller to another controller through Zigbee.
The communication between Internet and micro controller is established using Ethernet module and the controller is used in this project is ARM7 based LPC2148 32 bit controller.
The NXP (founded by Philips) LPC2148 is an ARM7TDMI-S based high-performance 32-bit RISC Microcontroller with Thumb extensions 512KB on-chip Flash ROM with In-System Programming (ISP) and In-Application Programming (IAP), 32KB RAM, Vectored Interrupt Controller, Two 10bit ADCs with 14 channels, USB 2.0 Full Speed Device Controller, Two UARTs, Two I2C serial interfaces, Two SPI serial interfaces Two 32-bit timers, Watchdog Timer, PWM unit, Real Time Clock with optional battery backup, Brown out detect circuit General purpose I/O pins.
wireless technology developed as an open global standard to address the unique needs of low-cost, low-power, wireless sensor networks.
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.
