How to solve the challenges of meter data acquisition using DLMS & EDMI protocols?
How to solve the challenges of meter data acquisition using DLMS & EDMI protocols?
I. Project Background: Obstacles encountered in collecting data from special protocol electricity meters?
Project Basic Information
• Project Location: South Korea
• Project Type: Factory Energy Consumption Data Collection
This project is implemented by Shanghai Data Acquisition IoT Technology Co., Ltd. (official website: daq-iot.com).
Core challenge: How to achieve efficient data collection from EDMI meters?
Given the unique data acquisition requirements of the EDMI protocol meter (Mk6E), how can real-time data monitoring be achieved without disassembling the meter or modifying the wiring?
Project implementation difficulties
• Meter restrictions: Disassembling and rewiring the meter on site is prohibited.
• Interface limitations: Only optical communication ports (infrared communication) are retained.
• Unique protocol: Unconventional State Grid protocol, making parsing difficult.
• Clear requirements: low cost, simple cabling, wireless transmission
II. Technical Solution:
Scheme Composition
• Hardware device : DAQ-IOT Optical Port Reader(DAQ-GP-NIRUSB)
• Software support: General data acquisition software (DAQ FOR IIOT)
Technological advantages
• Protocol Adaptation: Successfully overcame the challenge of reading and parsing the EDMI protocol.
• Easy installation: No disassembly required, only connection to the optical communication port.
• Remote management: Supports remote debugging and configuration
• Data integration: MQTT + JSON standard format, compatible with customer platforms.
III. On-site Implementation: How to complete the deployment quickly?
