I. Typical Pain Points of Park Energy Consumption Management
- Extensive energy consumption and uncontrollable idle power waste
There is no separate power monitoring for public areas, tenant workshops and production lines. Invalid energy waste cannot be located, and energy-saving measures lack reliable data basis.
- Frequent disputes over metering and charging
Manual meter reading is prone to omission and errors. Household/branch metering is inaccurate, cost allocation lacks objective data, leading to frequent tenant disputes.
- High and rigid power consumption cost
Under the two-part electricity tariff system, transformer load and demand cannot be monitored, making it difficult to optimize basic electricity fees and power factor adjustment charges.
- Lack of early warning for power safety hazards
Overload, electric leakage and abnormal power consumption cannot trigger real-time alarms, resulting in high equipment loss and high risks of power outages and safety accidents.
- Low management efficiency
Reliance on manual inspection and offline accounting leads to high operation and maintenance costs, while management decisions lack data support.
II. Management Upgrade Enabled by Smart Meters
- Full visualized energy consumption
Real-time collection of power consumption data from tenants, public areas and workshops, displayed on a unified platform with clear and traceable cost structure.
- Accurate metering and automatic billing
Support precise household and branch metering, compatible with prepaid and postpaid modes. Automatic bill calculation reduces manual errors and billing disputes.
- Data-driven energy saving
Power consumption curves and load analysis locate energy waste points, providing data support for energy-saving renovation and load optimization.
- Power safety early warning
Smart meters report overload, overvoltage, undervoltage and abnormal power events in real time, with system linkage early warning to reduce potential safety risks.
- Automated management operation
Realize remote meter reading, remote switch control and automatic cost allocation, transforming management from experience-driven to data-driven mode.
III. Core Architecture of the Solution
1. Perception Layer
2. Network Layer
- Local Networking: Data is aggregated through concentrators and collectors and uploaded to local servers, meeting high-security and localized management requirements.
- Cloud Platform Networking: Data is transmitted directly to the cloud via IoT channels, featuring flexible deployment and easy maintenance, suitable for small and medium-sized parks.
3. Application Layer
IV. Typical Application Scenarios and Value
- Commercial Parks & Office Buildings
Adopt three-phase / single-phase DIN rail meters to realize accurate household metering, automatic data upload, automatic cost accounting and electronic reconciliation, improving tenant service experience and capital recovery efficiency.
- Industrial Parks
Deploy three-phase multi-function meters to realize branch metering and load monitoring for workshops, production lines and transformers, providing data support for demand optimization, power factor charge control and energy-saving renovation.
- Property Parks
