European Petrol Station Interface
The European Petrol Station Interface , or EPSI for short, is a manufacturer-independent, open interface standard in the petrol station sector.
history
EPSI was launched from 1997 to 2001 on the basis of a research project initiated and funded by the mineral oil industry (1991 to 1996) by the Physikalisch-Technische Bundesanstalt (PTB) and the German Scientific Society for Petroleum, Natural Gas and Coal ( DGMK ). In 1995 the first EPSI filling station went into operation in Cologne. By the end of the standardization project in 2001, well over 1,000 filling stations had been equipped with EPSI technology. EPSI is standardized in DIN 26050.
technology
EPSI is based on the DIN measurement bus and is a client-server based bus. Various interfaces to other media have been developed in the past. For example a TCP / IP interface that was developed at the TU Berlin.
Areas of application
EPSI should enable the simple networking of devices in the petrol station environment. The devices such. B. Car wash, cash register and gas pump do not have to be supplied by the same manufacturer in order to communicate with one another. Wireless communication, e.g. B. enable via WLAN.
