Power device profile changing method and apparatus of one kind Plug

The present invention relates to a power apparatus, and device profile changing method of one kind of plug and play, belonging to the power communications technologies. In the present invention, when there is need to change the statute, the change notification receiving module specifications and recording time change statute, while suspending the statute change before parsing module corresponding to the Statute, changes corresponding to the Statute after starting parsing module; before treatment time change resolution module statute data cache data, and changes the time corresponding to the Statute after the change is transmitted to the parsing module parses the statute, in order to achieve the overall loading the new module parsing the statute, the invention in the case where the power device without stopping the operation, close the old module specifications to start a new analysis module, to ensure the normal operation of the entire power-line communications equipment, thereby increasing the flexibility of the system to update the statute module, reducing the duplication of development effort Statute Statute module developers, and improve the utilization rate of the statute module update efficiency.
