Remote Access to Images and Control Information of a Supervision System Through GPRS

Abstract Real time access to control infonnation of supervision systems in large installations is extremely important in order to be able to act in time to critical situations. In this paper the viability of remote access to this information via GPRS is evaluated. Also evaluated are the request protocol image reception and information about the state of the equipment in the system, as well as the average transfer rate in order to establish the update of the information in real time, obtaining update times, for image and/or control data, which are acceptable for a supervision and control system.
