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...
