Product Overview
The HGC Meter Data Concentrator is primarily used in remote meter reading systems, performing centralized data collection from heat meters, water meters, electricity meters, gas meters, valve control devices, and enabling remote data transmission. It is widely applied in heating, electricity, water supply, and natural gas industries. The device provides M-Bus and RS485 communication interfaces, making it compatible with slave devices using M-Bus or RS485 protocols. It can store collected data locally and connect to the internet via multiple communication methods such as 4G, 5G, LAN, and WiFi, enabling remote meter reading and monitoring functions.
Product Features & Advantages
- Remote upgrade and maintenance support: Supports OTA (over-the-air) remote upgrades, online management, and maintenance.
- Flexible development interfaces: Provides multiple secondary development interfaces, enabling easy integration into third-party meter reading management systems.
- High automation and reliability: Supports automatic periodic meter reading, automatic protocol parsing, offline operation, local data storage, fault reporting, and breakpoint retransmission.
- Wide compatibility: Compatible with a wide range of domestic and international water meters, electricity meters, heat meters, gas meters, ultrasonic heat meters, and flow meters.
- Integrated web-based management: Built-in web server allows configuration and management via browser, including parameter settings, manual meter reading, ID retrieval, historical data access, and acquisition cycle configuration.
- Dual metering modes: Supports both real-time active meter reading from the central system and local scheduled meter reading.
- Automatic time synchronization: The concentrator and gateway support automatic time synchronization, typically every 24 hours.
- Fault diagnostics and reporting: Supports system fault detection, diagnosis, and automatic reporting to the data center.
- Watchdog auto-recovery: Equipped with hardware watchdog function to automatically reset or reboot in case of system failure or power restoration.
