Remote control system using a gateway station for multi-protocol conversion

摘要

An information exchange system comprising a plurality of control nodes (2) and a plurality of remote user terminals (1), said control nodes (2) being able to send and receive information by means of signals being formated according to a first standard protocol, said remote user terminals being able to send and receive information by means of signals being formated according to a second standard protocol being different from said first standard protocol, wherein said system further comprises a gateway station (4) receiving from said control nodes signals being formated according to said first standard protocol, converting said signals into converted first signals being formated according to said second standard protocol and sending said converted first signals to at least one of said remote user terminals (1), and receiving from said remote user terminals (1) signals being formated according to said second standard protocol, converting said signals into converted second signals being formated according to said first standard protocol and sending said converted second signals to at least one of said control nodes (2).
