主要製品

スマート･ガス･メータは、ガスの流量測定に加え、ローカル･エリア･ネットワークや広域ネットワークへの無線接続により、インフラの保守、遠隔モニタ、および自動請求処理を行います。また、漏洩および衝撃検出システムを備えており、地震やガス漏れといった緊急時には即座に遠隔からガスを止めることができるため、安全性が大幅に向上します。スマート･ガス･メータはバッテリ給電式のため、システム構成において低消費電力デバイスがきわめて重要です。 STは、システム･レベルでの独自のアプリケーション･ノウハウや、半導体製品、評価ボード、ソフトウェア開発キットなどの幅広いポートフォリオにより、スマート･ガス･メータのスムーズな設計をサポートします。また、STの超低消費電力Sub-GHz RF通信ソリューションは、長距離通信（wM-Busや、LoRa®およびSigfox™といった独自LPWANプロトコルなど）と短距離通信（デュアル･インタフェースNFC / RFIDタグ、超低消費電力のBluetooth® Low Energy、および802.15.4システム･オン･チップなど）の主要通信プロトコルをすべてサポートしており、これらを超低消費電力マイクロコントローラSTM8LやSTM32Lと組み合わせることで、スマート･ガス･メータに求められる長いバッテリ駆動時間の実現に貢献します。

Our products and solutions

ST supports designers with our unique system-level application know-how and a compelling portfolio of semiconductor products, evaluation boards and software development kits to overcome the design challenges posed by smart gas meter applications.

Our ultra-low-power sub-GHz RF communication solutions support all major protocols: long-range – including WM-BUS and proprietary LPWAN protocols such as LoRa and Sigfox – and short-range such as dual NFC/RFID interface tags and ultra-low-power Bluetooth Low Energy (BLE) and 802.15.4 system-on-chips. Together with ultra-low-power STM8L or STM32L microcontrollers, our solutions help applications meet the battery lifetime expectancy needed in smart gas meters.
