Abstract
The invention relates to a method for acquiring real-time time of a data acquisition module of an intelligent electric meter based on master station time. The method is characterized in that: in the previous time synchronization process of the intelligent electric meter, the data acquisition module stores the time difference between the master station time and the electric meter time into a memory chip; and in the next time synchronization, the data acquisition module adds the master station time and the time difference in the memory chip to obtain the real-time time. Thus, the real-time time of the data acquisition module can be acquired in an intelligent electric meter without a clock chip and a clock chip power supply, the problem that the real-time time can not be acquired in the case of power failure of batteries in the prior art is solved, the energy waste caused by the power supply of the batteries is avoided, and the entire power consumption of the intelligent electric meter is reduced. The method for acquiring real-time time of a data acquisition module of an intelligent electric meter based on master station time has the advantages of simple and convenient application mode, low realization cost and relatively wide application range.
