The processing method has the disadvantages that when the power failure occurs in the home of the user due to the fault of the line between the concentrator and the user electric energy meter, the master station cannot timely acquire the power failure information of the electric energy meter, and the power company cannot provide line emergency repair service for the user at the first time of the power failure accident, and even know that the power failure occurs in the home of the user after the complaint of the user. With the development of communication technology and the increasing demand of people on the quality of power service, an electric energy meter with a function of reporting power failure events in real time and a concentrator with a function of reporting power failure events in real time are produced.
In the prior art, CN201510193470, "a method for testing a power failure event of an electricity information acquisition terminal in a simulation field", is used for detecting a common electric energy meter, and a power failure event can be detected only by powering on the electric energy meter or the acquisition terminal again after power failure.
