Modbus+4G enables smart electricity meters

In the era of rapid development in the Internet of Things (IoT) and smart grids, achieving efficient and stable remote collection and monitoring of electricity meter data has become a key requirement in the field of energy management. Shenzhen Huizhi Technology’s 4G industrial gateway, with its robust Modbus protocol compatibility and reliable 4G wireless communication technology, provides a dependable, all-in-one solution for electricity meter data integration.

Modbus+4G enables smart electricity meters

▶ Application Scenario Overview

Traditional electricity meter data collection typically relies on manual readings or wired communication, which suffers from low efficiency, high costs, and poor real-time performance. The Huizhi 4G gateway addresses these pain points through the following methods:

  • Remote Automated Collection: The gateway connects directly to electricity meters via Modbus RTU/TCP protocol, enabling real-time acquisition of data such as voltage, current, power, and energy consumption.
  • Wireless Transmission: Leveraging the 4G network, the gateway uploads data to cloud platforms or local servers, eliminating the need for complex wiring. This is especially suitable for distributed meter deployments in industrial parks, commercial buildings, photovoltaic power stations, and similar scenarios.
  • Edge Computing: The gateway features built-in data processing capabilities, such as filtering and alarm judgment, to pre-process raw data and reduce cloud-side load.

▶ Core Solution Advantages

Broad Compatibility

  • Supports the Modbus standard protocol, allowing integration with mainstream domestic and international meter brands (e.g., Siemens, Schneider, Wasion, etc.).
  • Provides RS-485/232 interfaces for flexible adaptation to various meter hardware.

Stable and Reliable Communication

  • 4G all-network design covers China Mobile, China Unicom, and China Telecom, ensuring adaptability in complex environments.
  • Features automatic reconnection and data cache retransmission mechanisms to guarantee data integrity.

Security and Ease of Use

  • Supports VPN, SSL/TLS encrypted transmission to prevent data leakage.
  • Offers a web-based configuration interface and remote management tools, supporting batch deployment and firmware upgrades.

▶ Future Scalability

The gateway supports integration with third-party platforms (such as Alibaba Cloud IoT, ThingsBoard, etc.), enabling future expansion to:

  • Linkage with photovoltaic and energy storage equipment for microgrid construction.
  • Integration with AI algorithms for power load forecasting.

▶ Conclusion

By leveraging the Modbus protocol, Shenzhen Huizhi Technology’s 4G gateway empowers intelligent metering, providing a complete “collection-transmission-analysis” chain for energy management. Against the backdrop of carbon neutrality goals, this solution will continue to help enterprises achieve green, efficient, and digital energy transformation.
