I. INTRODUCTION The evolving technology of the modern age has made it necessary to control the existing technologies efficiently and comfortably. The consumers expect the development of products that are easy to use and are efficient and which can be bought at the lowest possible cost from the industry. The daily difficulties related to lighting automation faced by people ranging from industry professionals to modern day housewives have inspired this project. The concept aims at controlling lighting appliances ranging from industries to sub-urban homes using a web based application at the front end complemented by a end user application developed for the aimed location. The concept features on controlling of lighting appliances in groups as well as individually. The color and intensity of the lights can also be changed. The quick access feature is provided by the predefined and user definable presets. The other features include scheduling options, obtaining live feedback, receiving notifications and maintenance pop-ups, bill estimation, power consumption.

II. SYSTEM ARCHITECTURE

For better understanding the system architecture has been divided into 3 parts namely the web based part, the software part and the hardware part.

Fig. 1

Fig.1 depicts the system architecture while the working of the different parts is as follows: The web based part: In this part the functionality provided to the user incorporating the web-services is present. The webpage will give the user options like scheduling, changing color and intensity, grouping etc. The website has been developed using HTML 5 which is the latest industry standard. The login for the page incorporates PHP script, which improves the security. The changes made by the user to his particular account will be reflected in the database. For the creation and manipulation of databases MySql will be used. To make the website look better jQuery scripts have been used along with Cascaded Style Sheets (CSS). The user will login which will open a variety of options for the user to manipulate. The user can select the tab provided for a particular option to make changes. The user can group a number of lighting appliances as he wishes and these changes will be modified in the database. Similarly the user can schedule the lights to go on/off using the calendar tab provided where he has to select a date when he wants his system to be completely on/off. The color and intensity of the lighting appliances can be changed using the intensity and color tab. All these changes will be reflected in the database. This database will be maintained at a secure server so that the company can also track the usage and suggest any changes or discrepancies if any. The server software will be Apache server, which is also an industry standard and is used extensively on various platforms. The web-based part will also contain the ‘admin’ login for the administrator to look after the system. The admin login id

and password will be different than that of the user and will contain additional features as compared to that of the user id as the admin can control and manipulate the entire system. The admin can monitor user activity and can provide maintenance. The admin and add and delete the appliance according to the users need. The Software part: In this the software will communicate with the hardware. It is somewhat like an interface between the website and the hardware. The user commands need to translate into ZigBee recognized codes. The GUI for the software will be developed using Visual Basic (VB), which is also an industry leading standard. The basic coding for the ZigBee will be done using breakthrough code. Obtaining values from the micro-controller for each of the order given by the user through the software will be in binary form, which then will be transferred to the database for further processing. The login form will contain functionalities for user and admin login. After selecting the type of login the respective form will be loaded which will provide the respective functionalities depending on the type of login. The user can directly access the functionalities like grouping, color and intensity options etc. The admin at the other end has to select which user he wants to manipulate and then he has access to all the functions that the user has and also the maintenance options. The admin part of the software will have a graphical image of a room in which he an option to add appliances directly at the socket in the room as the image will show the socket positions. This will give the admin a simpler and easy to add and remove appliance in a particular working place. Similarly the user will also have a graphical image to control the appliance rather than selecting the appliance from a list box or a drop down box. The software will be connected a database of which we will be using to store the data of all the appliances similar in way we will be doing it in the web-based application. The database will store the number of appliances, the working place data, the MAC addresses of all the appliances for the controlling. It will also save the current status of the appliance as well as the groups, presets and the calendar data into it. The User’s profile will also be saved on the database and login details of user as well as of the admin.

The Hardware part: The hardware components will basically incorporate the following:

1. ZigBee Transmitter 2. ZigBee Receiver 3. Appliances 4. Development Board 5. Micro-controller

The ZigBee works on RF(radio frequency) and hence can communicate wirelessly. The ZigBee is a low cost, low power, wireless mesh network standard. The low cost allows to be

widely deployed in automation applications. Lower power usage allows longer life. Mesh networking provides high reliability and more extensive range. ZigBee builds upon the physical layer and media access control defined in IEEE standard 802.15.4 for low rate WPAN’s. The specification goes on to the complete standard by adding 4 main components namely, network layer, application layer, ZigBee device objects and manufacturer defined application objects which allow customization and favor total integration. The user will send the information, which will include the changes he wants to make using the web-based part and then this information will be stored at server will further forward this information to the end user machine where the software part will play its role. It will act as in interface and for this information to the ZigBee controller in ZigBee recognizable format. The ZigBee controller in turn will communicate with the ZigBee modules. At this point of time the micro-controllers will come into effect, as they are required to encode as well as decode the information sent and received. All this communication will be bi-directional and will make it easier and better as well as efficient.

Fig. 2

Fig.2 depicts the ZigBee cluster interacting with other system components. As shown in fig.2 the dotted bi-directional lines denote a wireless connection while the solid bi-directional lines denote wired connections. Blocks M1, M2, M3, M4, M5, denote the ZigBee modules. The block µC denoted the micro-controller ATmega16. The block M1 acts as a ZigBee controller, which is an interface for sending and receiving data between the micro-controller and the other ZigBee modules. The other ZigBee modules mark the end appliances. All the ZigBee modules are to be function set in ZigBee ROUTER/END DEVICE AT mode and the parameters to be set are PAN ID which must be same for all the ZigBee modules in the network, Destination Address Low which must be set to 0 for router mode and Baud Rate which must be same for all the modules in the network, for example, 9600. The ZigBee modules to be used will be Digi International XBEE series 2 OEM RF modules.

The tree view shows various lighting appliances being installed at user end and sorted according to the floor number and room number. The grid view shows the status of the appliances, the color values, the intensity, the group-id, the group status, the CCT value, the floor number and the room number. The control panel on the right is used to change the values of CCT, to change the status of the selected appliance, and the color values. The buttons at the bottom are used to configure the hardware part and perform operations like selecting a layout of the room, adding an appliance, deleting an appliance, and adding an appliance to a group.

V. ENHANCEMNETS

This type of automation system is mainly used for home automation systems. Its future scope also involves controlling robo-arms or octo-copters. It can be used in factories where high load requirement is not present. It can be used for communication where a bit of noise disturbance is tolerable, as the ZigBee devices being used are not totally immune to noise. This project can also be further developed for mobile platforms so as to achieve greater mobility. The future scope of the project can also be extended to control each and every home appliance, which may include fans, air conditioners, or even kitchen appliances.
