Integrated telemetric and telecommand solution based on wireless technology for refinement to urban services

Abstract

Advances in embedded computer technology have brought about the technical and economic viability of the spread of microprocessed control systems, which today constitute a common resource in all kinds of electronic equipment. The inclusion of communications facilities in these devices enables remote access to their functions, creating conditions for the implementation of telemetric and telecommand systems. Amongst the benefits sought, are the reduction in operating costs and the improvement of the quality of service by means of online monitoring, an increase in efficiency in the use of shared resources, better integration with management systems and decision support, refinement to security and new applications enabled through inter-device interaction. Focusing on the potential of this technology, this project aims to put into action a research plan aimed at setting up an integrated telemetric and telecommand system based on wireless communication via the mobile phone network. Exploring the most upto- date telecommunications and internet technologies, the mechanism was conceived to operate on the standard GSM cell channel, using the GPRS protocol (GPRS is designed for applications which require telemetric and telecommand systems with mobility and reliable continuous flow of information). The applications envisaged include sectors such as public services, logistical control, patrimonial security, domestic billing, environmental monitoring and the telemaintenance of equipment. (AU)
