Company Background  

A major shipbuilding heavy industry enterprise operates across shipbuilding and repair, offshore engineering equipment, and heavy machinery manufacturing. In the past, energy consumption data for water, electricity, steam, and gas across its plant relied on manual meter reading and aggregation. This led to unclear energy accounting, rough management practices, and delayed data reporting, making it difficult to meet government mandates for online energy monitoring and constraining the company’s progress toward green manufacturing and digital transformation.

Solution Overview  

WideIOT has deployed energy data collection gateways to establish a complete energy data pipeline from the device layer to the platform layer, delivering comprehensive and reliable digital support for the energy management system. On-site instruments include various water, electricity, and gas meters, as well as steam flowmeters (primarily using the Modbus protocol). The energy data collection gateways use RS485 serial ports to poll multiple meters simultaneously, transmitting real-time energy data to both the enterprise energy management platform and the municipal monitoring platform. This enables functions such as energy monitoring, alerting, management, control, and data analytics, helping the factory achieve its goals of energy conservation, regulatory compliance, cost reduction, and operational efficiency.

Key Features

1. Versatile Connectivity – The gateways are equipped with multiple serial ports and network ports and support a wide range of communication protocols, including Modbus, DL/T645, IEC61850, and CJ188. They can integrate seamlessly with various smart meters for electricity, water, gas, and other utilities, enabling automated meter reading.

2. Industrial-Grade Reliability – Built to industrial standards, the gateways perform reliably in demanding factory and workshop environments. They support data retransmission with store-and-forward capabilities and multi-network backup to ensure data continuity and integrity. Remote configuration, diagnostics, and firmware upgrades are also supported, significantly reducing on-site maintenance costs.

3. Smart Alerting with Threshold Presets – Preset safety thresholds for energy metrics such as power factor, load rate, and energy intensity trigger automatic alerts when anomalies are detected. Notifications are sent to management via WeChat, SMS, or email, enabling rapid response to prevent energy waste and address potential safety hazards.

4. Multi-Center Data Sharing – The system supports simultaneous data transmission to multiple destinations, enabling seamless data sharing between the enterprise energy management platform and the municipal monitoring platform. This facilitates energy consumption analysis, auditing, and compliance reporting, ensuring that energy-saving initiatives are properly tracked and their effectiveness is clearly measured.

5. Extended Control Capabilities – By integrating with DCS, PLC, and other control systems, the gateway enables remote control of switches, valves, and other actuators. In the event of abnormal conditions, operators can take remote corrective actions to safeguard production, enhance safety, and minimize energy waste.
