Embedded web server application for industrial automation

Abstract

Web Server based monitoring has been an issue for industries as they make use of PC-based servers which consume large power and occupy large area. This limitation can be overcome by replacing the existing PC-based server by an Embedded Web Server using Raspberry Pi. The prime objective of this paper is to design a remote data acquisition system which is controlled by Linux portable ARM processor and web server application with General Packet Radio Service (GPRS) technology. This system focuses not only on device monitoring but also controlling it. The monitoring and data collection is accompanied by a Short Message Service (SMS), an email alert which is initiated in order to avoid the occurrence of a critical event. The system is capable enough to withstand power failure and capable of restarting from the point of failure.
