AI Technical Summary

Technical Problem

When installing battery-powered stationary measurement devices at multiple distributed installation locations, existing technologies suffer from long installation times and high battery consumption, especially when searching for a suitable LPWAN network. Traditional methods may require waiting for 15 minutes or more, resulting in low installation efficiency.

Method used

The Automatic Meter Reading System (ARS) is adopted, which uses a mobile installation device to send LPWAN connection candidate information, such as EARFCN, to the measuring device via short-range wireless communication. This helps the measuring device quickly establish an LPWAN connection. Combined with the LPWAN connection module, priority sorting search is performed, reducing installation time and battery consumption.

Benefits of technology

It significantly improves the efficiency of the installation process, reduces waiting time from minutes to seconds, and lowers battery consumption and installation costs.

Abstract

This disclosure relates to an automatic meter reading system (ARS) (1) for determining values ​​at multiple distributed installation locations and transmitting data containing said values ​​to a front-end system (HES) (3) via a low-power wide area network (LPWAN). The ARS (1) includes: an HES (3); multiple battery-powered fixed measuring devices (7), each measuring device (7) configured to be installed at one of the multiple installation locations and to determine said value at said one installation location, wherein each measuring device (7) includes an LPWAN connection module configured to establish a wireless communication connection to an LPWAN for transmitting data containing said value to the HES (3) via the LPWAN; and a mobile installation device (13) including a short... A short-range connection module is configured to establish a short-range wireless communication connection (15) to one of a plurality of measurement devices (7) to be installed at one of a plurality of installation locations. The short-range connection module is configured to send LPWAN connection candidate information to one of the plurality of measurement devices (7) to be installed at one of the plurality of installation locations via the short-range wireless communication (15). The LPWAN connection module of the one of the plurality of measurement devices (7) is configured to attempt to establish an LPWAN handshake connection at the one of the plurality of installation locations for the first time based on the received LPWAN connection candidate information.
