Embodiment 1

[0043] The present invention provides a method for actively judging power failure and restoration, including a power failure judging method and a power restoration judging method, such as figure 1 As shown, the method for judging power recovery includes:

[0044] Get the power outage record set from the database, and extract the power outage time from the power outage record;

[0045] Obtain the difference between the power outage time and the system time. If the difference is greater than the preset threshold, check whether the communication with the terminal has been restored. If it has been restored, check the call test record to determine whether the power meter has been called and tested within the predetermined time. event;

[0046] If the power outage event of the electric energy meter has not been called and tested, then check the installation of the electric energy meter, and determine whether there is a smart electric meter according to the query result;

[0047] I...

Abstract

The embodiment of the invention proposes a power-off and power-on active judgment method, and belongs to the field of power equipment. The method comprises a power-off judgment method and a power-on judgment method, and specifically comprises the steps: obtaining a power-off record set from a database, and extracting power-off time in the power-off record; obtaining the difference between the power-off time and the system time, determining whether there is a need to detect a power-off event of an electric energy meter or not according to the difference, and carrying out the subsequent processing according to the detection result; obtaining the accurate power-off and power-on information through combining the record stored in the database with multiple presetting conditions, thereby solving problems of power-off and power-on alarm leakage and wrong alarm of a conventional terminal. A terminal equipment maintainer carries out the maintenance and change of a terminal with a fault timely according to the information, thereby guaranteeing the normal operation of power equipment, reducing the normal operation of the power equipment, reducing the probability of a power fault, and improving the user experience.

Description

technical field [0001] The invention belongs to the field of electric equipment, in particular to a method for actively judging power failure and recovery. Background technique [0002] Currently, due to technical limitations, the power supply department cannot monitor the power outage of a single user. Only when the user actively reports to the power supply department, the power supply department can learn the news of the user's power outage, which will imperceptibly reduce the user's experience. Contents of the invention [0003] In order to solve the shortcomings and deficiencies existing in the prior art, the present invention provides a method for solving the situation of missing alarms and false alarms of power failure and recovery in the existing terminals, and terminal equipment maintenance personnel can timely maintain the faulty terminals according to the information. and replacement, to ensure the normal operation of power equipment, reduce the probability of p...
