The invention discloses an intelligent remote
upgrade method of a collector in an electric meter collecting
system. The method comprises the following steps of making a main
station send a starting
upgrade command to the collector; making the collector extract detection information from a command frame in the starting
upgrade command; making the collector send a tentative frame to an
electricity meter within a domination area, executing the next step if an effective frame is successfully collected, or exiting upgrade if the effective frame is not successfully collected; making the main
station send an upgrade message to the collector; making the collector extract new
software version information from the upgrade message, comparing the new
software version with a current
software version, executing the next step if the new software version number is higher than the current software version number, or exiting upgrade if the new software version number is not higher than the current software version number; making the collector send a response frame to the main
station, exiting upgrade if a follow-up frame is not received within an
effective time range, decompressing the received frame and afterwards storing the frame in
external storage equipment if the frame is normally collected, and sending an upgraded frame after an upgrade message
tail frame is received. According to the intelligent remote upgrade method of the collector in the electric meter collecting
system, the collectors with addresses and without addresses can be subjected to intelligent remote upgrading.
