Abstract: This paper provided a method for remote update for routing management platform of power line carrier communication．It designs a complete set of communication protocol,and puts forward several mechanisms to assure the update of real-time and efficient．So secure,reliable and low-cost remote management can be achieved．It is generic and can guide practice to deal with the related problems.This described method has been tested at the laboratories and in the fields which can achieve real-time update for routing management platform,save a lot of manpower and material resources,greatly reduce the maintenance costs of L-PLC routing software．It can be applied for Automatic Meter Reading system in low-voltage power line carrier communication,especially for the system which consists of master station,concentrator,GPRS module and routing management platform.

Key words: Routing management platform,Real-time update,L-PLC,AMR,Secure,Reliable
