Electric energy meter communication method and system based on follow-up frame dynamic registration

The invention provides an electric energy meter communication method and system based on follow-up frame dynamic registration, and the method comprises the steps: initializing a communication channel and a preset number of follow-up frame storage spaces into an unregistered state after an electric energy meter is powered on; when the first frame of the data sub-frame is monitored, performing dynamic pairing registration on the communication channel and the subsequent frame storage space according to the registration states of the communication channel and the subsequent frame storage space and the preset emergency importance priority of the data frame; data frames are stored in the paired subsequent frame storage space for communication, and when data transmission is finished, a communication channel and the paired subsequent frame storage space are cancelled to be in an unregistered state. Through a follow-up frame dynamic registration mechanism, the coupling degree of each channel is low, resources can be r
