The invention discloses an
electricity consumption
information acquisition system clock management method and device. The method comprises an
electric energy meter
clock time checking step, wherein the
electric energy meter
clock time checking step comprises the specific steps of S1, enabling an
electricity consumption
information acquisition system to regularly obtain a clock of each
electric energy meter in an area for carrying out time checking, and searching the electric energy meters, the clock errors of which exceed a preset range, so as to obtain all the clock overproof electric energymeters; S2, judging a
clock error magnitude of each searched electric energy meter with overproof clock, if the
clock error magnitude is smaller than a preset error threshold, turning to execute the step S3, and otherwise, turning to execute the step S4; S3, generating a
broadcast time checking message through a
concentrator so as to carry out
broadcast time checking on a target electric energy meter with overproof clock; and S4, reporting an electric energy meter clock overproof event to a
master station so that the
master station carries out single-meter time checking on the target electricenergy meter with overproof clock. The method and device have the advantages of being simple in realization and low in cost, realizing the
intelligent management for the electric energy meter clocks,and being high in clock
correctness and
management efficiency.
