Embodiment 1

[0033] Figure 6 A flow chart of a data backfill method according to an embodiment of the present invention is shown. Continue to refer to figure 1 and Figure 4 , the data received at the data receiving end before and after the interruption of data communication is as follows figure 1 As shown, the data files containing missing data recorded by the data acquisition terminal are as follows Figure 4 In the situation shown, using the data backfilling method of the embodiment of the present invention, first, obtain such as Figure 4 As shown in the data file including the lost data, then, compare the collection time [13:20:06] of the data first received by the data receiving end after the recovery of the data communication with the collection time of each data in the obtained data file Time comparison, since there is only one data collection time [13:20:06] in the obtained data file, therefore, the data collection time [13:20:06] in the obtained data file is determined as th...

Embodiment 2

[0044] This embodiment provides a data backfilling device for implementing the above data backfilling method, the device includes a data acquisition module, a comparison module, a determination module, a data extraction module and a filling module.

[0045] Continue to refer to figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 ,Such as Figure 6 As shown, the data acquisition module is used to obtain such as Figure 4 Data files shown including missing data. The comparison module is first used to convert the figure 1 The shown data receiving end compares the collection time [13:20:06] of the data first received by the data receiving end after the recovery of data communication with the collection time of each data in the obtained data file, since there is only one Data collection moment [13:20:06], so, then, will figure 1 The data collection time [13:20:01] last received by the data receiving end before the interruption of data communication is compared with t...

Abstract

The invention provides a data backfill method and device. The data backfill method comprises the steps that a data file comprising lost data is obtained from a data collection end; the obtained data file is searched for the data loss end point and start point by comparing the data collection time of a data receiving end with the data collection time of the data collection end and comparing data values of the data receiving end and the data values of the data collection end, so that data between the data loss start point and the data loss end point in the obtained data file are determined to be within the range of the lost data of the data receiving end; the determined data in the lost data range are extracted; the data lost part of the data receiving end is filled with the extracted data.

Description

technical field [0001] The present invention relates to the technical field of data communication, and in particular, relates to data backfilling technology. Background technique [0002] The data backfilling in this article specifically refers to when the data collection terminal records the collected data and sends the collected data to the data receiving terminal, when the data communication between the data receiving terminal and the data collecting terminal is interrupted for some reason When the data is interrupted, the data receiving end may lose data. Therefore, after the data communication between the data receiving end and the data collecting end is resumed, it is necessary to obtain the data recorded by the data collecting end that was not received during the data communication interruption. The data received by the terminal is used to backfill the data, so as to present the complete received data on the data receiving terminal. [0003] In the prior art, data ba...
