The data verification method comprises the following steps:
1) The first day, the electric power acquisition terminal reads daily freezing data, in this embodiment, reads daily freezing electric quantity of the electric power acquisition terminal (electric energy meter) on one day, records the daily freezing electric quantity as data1, finds a corresponding storage position according to a daily freezing time scale, and stores the data;
2) The next day is entered, the electric power acquisition terminal carries out day freezing data reading, and the same is carried out, and the day freezing electric quantity of the electric power consumption terminal in one day is recorded as data2;
3) Comparing data2 with data1, and preliminarily judging whether data2 is correct or not by using the size comparison result of data1 and data 2:
3.1 Judging whether data2 > data1 is true or not, if yes, entering step 4); if not, preliminarily judging that the data2 has a problem, and entering the step 3.2 if not;
3.2 A data2 supplementing process is started, daily freezing data are read, and the data are read at certain time intervals, as in the embodiment, the data are read once every hour, and similarly, the daily freezing electric quantity of the last day is read, and the step 3.3) is carried out after refreshing the data2 once every reading;
3.3 Judging whether a day has elapsed, i.e. a day after 24 points have been crossed; if yes, the data is still wrong until the end of the present day, and the steps 7) and 4) are entered; if not, entering step 3.4);
3.4 Judging whether data2 > data1 is true or not, if yes, entering step 4); if not, the current data2 still has problems, is not stored, and is continuously read, and the step 3.2 is returned;
4) The third day is entered, the electric power acquisition terminal carries out day freezing data reading, and the day freezing electric quantity of the electric power consumption terminal in one day is also read and recorded as data3;
5) Comparing data3 with data2, and judging whether the data2 and the data3 are correct or not by using the size comparison result of the data2 and the data 3:
5.1 Judging whether data3 is more than data2 is true, if so, because data2 is more than data1, indicating that the current data2 is correct, finding a corresponding storage position according to a daily freezing time scale, then storing the current data2, and entering the step 6); if not, preliminarily judging that the data3 has a problem, and entering step 5.2 if not;
5.2 A data3 flow is supplemented, daily freezing data reading is carried out, and the data is read at certain time intervals, as in the embodiment, the data is read once every hour, and similarly, the daily freezing electric quantity of the last day is read, and the step 5.3) is carried out after refreshing the data3 once every reading;
5.3 Judging whether a day has elapsed, i.e. a day after 24 points have been crossed; if yes, the data is still wrong until the end of the present day, and the steps 7) and 6) are entered; if not, go to step 5.4);
5.4 Judging whether data3 & gtdata 2 is true or not, if so, finding a corresponding storage position according to a daily freezing time scale, then storing the current data2, and simultaneously entering the step 6); if not, the current data3 is judged to still have problems, the data is not stored, the copying is continued, and the step 5.2 is returned;

7) The data is wrong, 1 is arranged on the corresponding position of the stored information mark, and then the data is reported to the master station through an alarm.
In the steps 3) and 5), the step of performing the additional reading is performed, because the daily frozen electric quantity on the electric energy meter is not updated, and thus, the data of the electric power acquisition terminal is inconsistent with the data of the electric energy meter. For example, when the time of the electric energy meter is inconsistent with the time of the electric power collection terminal, the time of the electric power collection terminal is the third day, and the time of the electric energy meter stays on the second day (a condition that a difference of a few minutes may exist in general), the day freezing data2 of the last day collected by the electric power collection terminal is actually data1, so that collection errors can occur, and the problem can be solved by carrying out the copying.
