1、 Project background: Is there any obstruction in the collection of special Protocol electric meters?

Basic project information

• Project location:Chongqing Port West PV power station(CGN Chongqing)

Project Type: PV Power Generation and Grid Connection Project Energy Monitoring

Core challenge: How to achieve efficient collection of EDMI meters?

How to achieve data monitoring of EDMI Protocol electric meter (Mk6E) without disassembling or changing the wiring, in the face of special collection requirements?

Difficulties in project implementation

Electricity meter restriction: On site electricity meters are prohibited from dismantling and connecting wires

Interface limitation: Only optical communication port (infrared communication) is retained

Protocol Special: Unconventional State Grid Protocol, difficult to parse

• Clear requirements: Low cost, easy wiring, wireless transmission

2、 Technical solution: How can infrared acquisition break through the barrier ofProtocol?
