ATMEL AVR Based 32-BITS Data

In Embedded web technology a smart devices are controlled from a remote location via internet, through a web server. A client which may be a desktop computer or a mobile phone with the web browser, connected to the internet can control and monitor all actions of the smart device with special permissions and authentication. The combination of smart device and web server is Internet appliance. Handling of heavy machinery equipments in several places like, sugar industries, cotton mills, and substation is strenuous task. Collecting information of such heavy equipments like, noting down their operating parameters, their operating conditions is risky. Hence an effective system has been evolved to overcome such difficulties, which is known as SCADA. SCADA abbreviation is supervisory control and data acquisition. It has data acquisition feature as major role than controlling. It is mostly operated through Internet. The purpose of SCADA is to provide information regarding the equipments attached to it. It is the new technology evolved to overcome problems regarding data collection, decreasing human labor making dynamic decisions, communication with other substations. SCADA is used in generating stations and substations to communicate with other substations and control center via satellite. It’s application in substation; is being presented in this project. The threats that it is undergoing are also being presented. The protective measurements involved to protect it are clearly elucidated.
