An intelligent three-phase power supply II-type collector is provided with a three-phase power supply working power supply module, an MCU control module, an RS485 communication module, a carrier communication module, a storage module and other functional modules. The three-phase power supply working power supply module comprises a power supply module for supplying power to the feed network circuitmodule by an ABC three-phase power supply and a power supply module for supplying power to the MCU module, the RS485 module and the carrier communication module; the RS485 communication module is used for processing a large amount of control chip software according to the phenomenon that various protocols of RS485 meters are different on site through RS485; the carrier communication module uploads power consumption data in a power line carrier mode through power line carriers and provides the power consumption data for the remote centralized meter reading system. And the MCU control module performs conventional stora
