I. Typical Pain Points of Park Energy Consumption Management

1. 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.
2. 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.
3. 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.
4. 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.
5. 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

1. 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.
2. 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.
3. Data-driven energy saving

   Power consumption curves and load analysis locate energy waste points, providing data support for energy-saving renovation and load optimization.
4. 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.
5. 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

1. 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.
2. 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.
3. Property Parks

   Adopt prepaid smart meters to implement the pay-first-use-later mode and reduce arrears risks. Support automatic energy cost allocation for public areas and provide fair and transparent billing basis.
