REMOTE ACCESS TO ELECTRONIC METERS USING A TCP/IP PROTOCOL SUITE

摘要

An electronic meter incorporates a TCP/IP protocol suite and an HTTP server (24) to provide two-way access to the meter incorporated into a gateway (20) serving multiple meters connected through a power line or wireless two-way network. The gateway (20) may incorporate an HTTP server (24) for accessing data from multiple meters (40) and for transmission of data to individual meters (40). Other aspects of the disclosed system include the use of a common gateway interface (26) for remote access to meter data and to set meter parameter using HTML forms in HTTP browsers; remote reading and setting of multiple meter parameters using a TCP/IP protocol suite; a TCP/IP protocol suite implemented in designated notes in a CEBus LAN (42) with remote access through TCP/IP (43) to routers and broutes and to individual meters on the LAN; and a SLIP-PPP (21) enabled gateway for remote TCP/IP access (22) through a serial interface to a single or multiple meter parameters.
