The invention relates to the electric network pollution data collection technology, in particular to an electric network pollution data star-shaped collection system based on a PQDIF standard. The electric network pollution data star-shaped collection system based on the PQDIF standard solves the problems that an existing electric network pollution data collection system is poor in data collection real-time performance, poor in data transmission stability, low in data transmission speed and poor in data sharing performance. The electric network pollution data star-shaped collection system based on the PQDIF standard comprises power quality monitors, carbon footprint power monitors, a monitoring master station, a database server, client sides, exchanges, gateways and power lines, wherein all the power quality monitors and the first exchange jointly form a star-shaped topological structure, all the carbon footprint power monitors and the second exchange jointly form a star-shaped topological structure, and all the client sides and the fourth exchange jointly form a star-shaped topological structure. The electric network pollution data star-shaped collection system based on the PQDIF standard is suitable for collection of electric network pollution data.
