System for remote transfer and collection of data, in particular from meters
First Claim
1. A system for remote transfer and collection of data such as quantity of energy or fluid measured by meters, each meter including a data storage and transmission unit, said system comprising:
- collection means collected to a common wire connection; and
normally open addressable switch members disposed between said common wire connection and each of said meters, each said switch member including means responsive to a unique interrogation signal sent by the collection means over said common wire connection for closing said switch member and thereby enabling a stream of data to pass from a data transmission unit associated with a meter to said collection means; and
wherein each data storage unit contains data relating to the identity of its associated meter, which data is independent of the address of the associated switch member which address corresponds to the physical address of the switch member, wherein each corresponding data transmission unit includes means for transmitting data indicative of the identity of the meter to said collection means when interrogated.

Abstract
A system for remote transfer and collection of data such as quantities of energy of fluid measured by a utility meter. Each meter includes a unit for storing and transmitting date from the meter to a remote data collector via at least one common wire connection. The switch contains a memory having a unique ID code. The switch is selectively closed in response to an interrogation signal bearing the ID code of the switch in order to enable a stream of data to pass from the meter to the data collector, this stream of data including a meter identity indication different from the switch ID code.
