Construction of Distributed Sensors Network Based on DTP/DIA

Present paper describes one of the systems with distributed data acquisition. The presented online sensors network covers the North-west region of Russia. Sensors measure atmospheric parameters: temperature, humidity and pressure. Measured data are transferred through Internet channels to database server every 5 minutes and may be also stored locally on the side of data source. All the acquired information is represented on the web-server http://thermo.karelia.ru/eng/. The sensors net is functioning on Data Transfer Protocol for Distributed Information Acquisition (DTP/DIA), which was designed especially for these purposes. The main features of DTP/DIA are simple implementation, reliability, ability to resolve various sources of information, support of up to 16 millions unique devices. In this net DTP/DIA uses TCP/IP packet as envelope.
