Permanent Switchboard Monitoring using Embedded Web Server

Abstract

The proposed paper discusses the realization of a system  prototype  able  to  perform  a  permanent  monitoring  of  a  switchboard  in  order  to  allow  the  manufacturer  the  complete  management of all the measurable quantities in the switchboard, specially the sensed voltage for each line. The main purpose is to prevent any fault that can affect the switchboard and provide an  instant  alarming  if  anomalous  values  are  revealed.  The  significant   aspect   of   our   prototype   is   the   internetworking   between   several   standard   network   protocols.   In   fact,   the   acquisition  network  sends  the  acquired  data  using  the  EIA  485  serial protocol. These data are then collected into an embedded web  server  ad-hoc  developed.  The  server  can  be  connected  to  the  Internet  in  a  wired  and/or  wireless  way  using  the  IEEE  802.3   (Ethernet)   and   the   IEEE   802.11   (Wi-Fi)   protocols.   Finally, the web server uses standard TCP/IP protocols, such as HTTP   to   manage   the   web   pages   and   SMTP   to   dispatch   automatic alarm notifications via e-mails.
