s4, reporting a power failure event: and reporting the current power failure event.
According to the power consumption information acquisition terminal power failure event reporting, whether the power failure event is abnormal or not is judged through preliminary screening based on power failure recovery time and comprehensive research and judgment based on voltage data after the power failure event is generated, the abnormal power failure event is screened by combining two judging processes, the power failure event is reported only when no abnormality exists after two judging processes, a large number of false alarm events can be screened, the accuracy of reporting the power failure event is greatly improved, the occurrence of false alarm is reduced, and the accuracy of fault research and judgment is greatly improved.
In this embodiment, the step S1 includes: when the power supply voltage is monitored to be lower than a preset power failure voltage threshold value, judging that the acquisition terminal is powered off, generating a corresponding power failure event, and when the power supply voltage is monitored to be higher than a preset power restoration voltage threshold value after the power failure event is generated, judging that the acquisition terminal is powered back, and generating a corresponding power restoration event.
In a specific application embodiment, a power failure voltage threshold and a complex voltage threshold are configured by taking a reference voltage with a specified proportion, preferably taking 60% of the reference voltage as a power failure voltage threshold and 80% of the reference voltage as a complex voltage threshold, and generating a power failure event is shown in fig. 2 and table 1.

In this embodiment, when the preliminary determination is performed in step S2, the determining includes determining a sequence relationship between the power failure time and the power restoration time, and if the power restoration time is earlier than the power failure time, determining that an abnormality exists. The logic for the formation of the power failure event is: when the power supply voltage of the terminal is lower than the power failure occurrence voltage limit value, a terminal power failure event is generated, after the power failure event is generated, when the power supply voltage is higher than the power failure recovery voltage limit value, a power recovery event is generated, namely the power recovery event must be later than the power failure event, and if the power recovery event is earlier than the power failure event, the power recovery event is abnormal. In the embodiment, the abnormal power failure event is identified by fully utilizing the power failure event forming logic of the acquisition terminal, so that the reporting strategy of the power failure event of the acquisition terminal is optimized.
When the preliminary judgment is carried out, the method also comprises the step of judging whether the data formats of the power failure time and the power restoration time are correct, such as whether the data formats are error data such as empty or messy codes.
When the preliminary judgment is performed, the method further comprises the step of judging whether the duration of the power failure time meets the preset requirement, wherein the duration of the power failure time is the power-on event occurrence time-power failure event occurrence time, if the duration of the power failure event is smaller than the preset minimum effective interval of the power failure time, the power failure event is judged to be an abnormal power failure event such as an instantaneous fault or remote signaling jitter, and the minimum effective interval of the power failure time can be specifically set according to the actual requirement.
In this embodiment, when the preliminary determination is performed in step S2, if any one of the following is specifically satisfied: and if the power restoration time is earlier than the power failure time, the power failure time and/or the power restoration time format error are met, or the duration time of the power failure time is smaller than the minimum effective interval of the preset power failure time, judging that the power failure event is abnormal. Through the steps, the power failure event of logic errors, the power failure event of error data such as empty or messy codes, the transient fault or the short-time power failure event such as remote signaling jitter and the like can be quickly and preliminarily screened, and unnecessary comprehensive judging steps and error reporting of abnormal power failure events are reduced.
After the preliminary screening is carried out on the power failure event, if the power failure event is judged to be an abnormal power failure event, the terminal only carries out local storage, and the normal mark position 0 of the event is marked, so that the power failure event is not sent; if no abnormality is determined, step S3 is executed to perform comprehensive research to further determine the validity of the event.

In the specific application embodiment, when whether the event is configured as a normal zone bit, if the event is generated by the mining terminal, after waiting for a preset time period, the event is normal, otherwise, the event is abnormal; when whether the event is effective or not is configured, if the power failure event corresponds to the duplicate event, the event is effective, and the user acquisition system generates an effective identification bit through the matching of the station area outage and the duplicate signal.
In the above preliminary screening step, the method may further configure and screen out a power failure event generated by an error under the condition of non-external power outage such as automatic restart of the terminal, so as to avoid reporting the power failure event generated by the error under the condition of non-external power outage such as automatic restart of the terminal.

And 3, after the step is finished, the power failure event which is judged to be abnormal is sent to a main station of the electricity consumption information acquisition system, and is stored locally, and the normal mark position 1 of the event is obtained. If it is determined in the steps S2 and S3 that there is an abnormality, the control unit stores the generated power failure event locally and does not report the power failure event, and the event normal flag is set to 0.
