Centralized metering device and SV data forwarding method thereof

The invention belongs to the technical field of electric energy meter metering, and particularly relates to a centralized metering device and an SV data forwarding method thereof. The method specifically comprises the following steps: in order to solve the problem that the centralized metering device cannot dynamically forward the SV in a running state, the serial number of an SV receiving and metering function module is determined through a man-machine assembly module, and then the group number of the SV is determined from the determined SV receiving and metering function module so as to complete the forwarding of the required SV data. According to the invention, under the condition that equipment is not restarted, required SV data can be dynamically screened from multiple groups of SV inputs for forwarding, the problem that the centralized metering device cannot dynamically forward the SV in a running state is effectively solved, and the precision test of the centralized metering device is conveniently supp
