Power management system

The invention provides a power supply management system, and the system comprises a plurality of power supply boxes which are connected in parallel, each power supply box comprises a plurality of intrinsic safety power supply assemblies which are connected in parallel, and the intrinsic safety power supply assemblies are used for obtaining the operation data of the corresponding intrinsic safety power supply assemblies; and each intrinsic safety power supply assembly comprises a micro-control unit and a data analysis unit, and the micro-control unit is used for sending the operation data to the data analysis unit through a carrier communication circuit. The power management system provided by the invention can digitize and monitor the operation data of the intrinsically safe power supply assembly, can analyze and process the operation data, can generate fault early warning when the intrinsically safe power supply assembly breaks down, improves the intelligent degree and safety of the power management system,
