Driven by the "dual carbon" goals (carbon peaking and carbon neutrality), industrial parks, as major energy consumers, are facing an urgent need to transition from extensive management to refined operations. In the past, electricity meters, water meters, and chiller units operated in silos, leaving energy data scattered like isolated islands. Leaks and inefficiencies were difficult to detect, and energysaving strategies had no data foundation.

Therefore, systematic, realtime monitoring of energy consumption in industrial parks is not only about keeping a "clear account" of every kilowatthour and every ton of water — it is also about uncovering energysaving potential through data insights and avoiding safety risks. It serves as the digital foundation for parks to move toward green, lowcarbon, and smart operations. To address this, WideIOT provides a comprehensive and reliable energy data collection gateway solution.

I. What Equipment Does It Collect?

1. Power Systems

Includes smart meters (monitoring electricity usage in office buildings, factories, and charging stations), distribution cabinets (voltage, current, power factor of main incoming cabinets), and photovoltaic inverters (power generation and instantaneous power from solar panels).

2. Water Supply / Heating Systems

Includes ultrasonic flow meters (monitoring total water usage and landscaping irrigation water usage), water pressure sensors, and thermal energy meters (monitoring chiller supply/return water temperature and heat).

3. Gas / Compressed Air Systems

Primarily gas flow meters to monitor natural gas consumption or compressed air flow from air compressor rooms.

4. Environment & HVAC

Includes temperature and humidity sensors (installed in equipment rooms and warehouses), central chiller unit PLCs (monitoring chilled water supply/return temperature and compressor frequency), and lighting circuit PLCs.

II. What Protocols Does It Support?

Modbus RTU/TCP – The most common protocol, used to connect to the vast majority of water, electricity, and gas meters, as well as temperature and humidity sensors in the park.

DL/T645 – Specifically used to interface with smart meters compliant with State Grid standards, allowing direct reading of meter base values, demand readings, and other raw data.

IEC 104 / 61850 – Mainly used for photovoltaic inverters, energy storage PCS (power conversion systems), and power distribution protection devices. These are high realtime protocols unique to power systems.

BACnet – For large industrial parks, central air conditioning and building automation systems typically use this protocol.

CJ/T 188 – Used to collect data from flow meters for purified or demineralized water.

III. Where Is the Data Transmitted?

Uplink:The gateway uses builtin 4G/5G (no cabling required), Ethernet, or WiFi for data transmission.

Access Protocols:The gateway standardizes the collected data into formats such as MQTT (standard IoT protocol), HTTP, or Modbus TCP.

Target Platform:The data is ultimately aggregated into a park energy management platform (e.g., WideIOT Cloud, customer's private cloud, or Alibaba Cloud/Huawei Cloud) for storage and analysis.

IV. What Functions Does It Provide?

1. Realtime dynamic dashboard on the park's central monitoring screen

Displays key parameters such as instantaneous power, current, voltage, water pressure, and flow for each building and critical piece of equipment in real time.

2. Customizable alerts

Users can set custom thresholds. When an alarm is triggered, the system sends notifications via WeChat, SMS, and email, enabling rapid fault location and corrective actions to ensure energy safety.

3. Energy reports for daily/weekly/monthly/yearly periods

Supports comparative analysis by building, floor, equipment type, and energy category (electricity, water, gas, heat), helping quickly identify anomalies and usage patterns.

4. Remote control and maintenance within permission management

Enables remote control, remote programming and debugging, and remote program upload/download for various automated PLC devices, improving work efficiency and management level.
