Title:
METHOD AND SYSTEM FOR READING INTELLIGENT UTILITY METERS
Document Type and Number:
WIPO Patent Application WO1999045510
Kind Code:
A3
Abstract:
A meter reading system and translation system as shown in Fig. 1 including an external modem module (EMM) (14), a hub (18), and a data collections system (20). The EMM communicates with one or more utility meters (12) and is preferably selected on the basis that it incorporates a communication format that is compatible with the communication format of the utility meter so that the meter does not require modification to be communicatively coupled to the EMM. The EMM obtains meter data from the meter and converts the data to a radio frequency (RF) format. The RF formatted data is then transferred to the hub. The hub then translates the RF data into an analog or digital telephone communication format, which is then transferred to the data collection system. The data collection system needs to recognize one communication format rather than attempting to accommodate numerous message formats.
