An Embedded Web Server for Industrial Automation

In the present IT era, there is a great need of fully automated industrial system. With the growing popularity of Internet and the development of embedded technology, Web technology has been extended to the development and application of embedded system. In the future pervasive computing environment, people would be surrounded by a great multitude of microcomputers that would be embedded in home appliances, factory devices, and so on. It is a better choice for these devices to be embedded a Web server. An embedded Web server (EWS) is a microcontroller that contains an Internet software suite as well as application code for monitoring and controlling systems. The main aim of the project discussed in this paper is to use the personal computer (PC) with the Ethernet card to send the messages to remote locations which is received by the 32-bit ARM processor in order to control the devices in the real-time environment. By using this project, it is possible to change the status (ON/OFF) of any appliance connected to ARM processor board via Internet. The messages from the PC can also be sent to any remote locations in the world using this technology. The codes for the implementation of this project have been written in embedded C language as it is easy to understand and is suitable for the embedded system design. This project has been designed for monitoring and controlling the status of two devices. The client can monitor and control the status (ON/OFF) of the devices via Internet from any corner of the world.
