Document Type and Number:
Japanese Patent JP2007535182
Kind Code:
A
Abstract:
In a method and system of remote metering the consumption of utilities like electricity, water or gas, each of a plurality of remote meters (RM) measures a consumption and reports the measured consumption to a concentrator (C). The concentrator (C) communicates with a plurality of remote meters (RM) in order to collect consumption data and perform tasks related to the administration of its associated remote meters (RM). Each remote meter (RM) has a host controller (MCM) and a program memory storing programs for execution by the host controller (MCM). In order to update some or all of the application programs running on the host controller (MCM) of the remote meters (RM), the concentrator (C) transmits program data to the remote meters (RM) and the remote meters (RM) receive the program data and update at least a portion of the program stored in the program memory in accordance with the received program data.
