Embodiment 1
[0043] For ease of understanding, see figure 1 , Embodiment 1 of a data restoration processing method provided by the present application, comprising:
[0044] Step 101. Add header and tail verification information to the collected sensor data. The header and tail verification information includes: header identification, tail identification and verification information.
[0045] It should be noted that the collection of sensor data is completed by the data collection gateway. After the sensor data is collected, the data collection gateway will add labels to the head and tail of the sensor data, and insert verification information into the data content. To be precise It is a check digit. The collection of sensor data has a time period, and a piece of sensor data is obtained every other cycle. Therefore, there is a sequence between the previous data and the next data, so the header identification of each sensor data is It is set to be consistent with the tail mark of the previo...

The invention discloses a data restoration processing method and device. The method comprises the steps of adding head and tail verification information to collected sensor data,when the head identifier of the current sensor data is inconsistent with the tail identifier of the previous sensor data or the total length of the current sensor data obtained by verification according to the verificationinformation is inconsistent with the length threshold, obtaining missing sensor data in the case of supplementary reading failure,performing missing bit verification on the missing sensor data according to a preset bit operation mode to obtain all missing bits of the missing sensor data, the missing bits including corresponding missing moments,calculating restoration parameters related to the missing moment,and calculating target sensor data of the missing bitsaccording to the restoration parameters and a preset restoration formula, and performing restoration operation. According to the method and the device, the technical problem of relatively low efficiency and security of data restoration and even integration due to lack of targeted analysis on the relationship between the data in an existing data restoration processing technology is solved.
Description
technical field [0001] The present application relates to the technical field of data processing, and in particular to a data restoration processing method and device. Background technique [0002] The power Internet of Things is a smart service system that focuses on all aspects of the power system, fully applies modern information technology and communication technology, and realizes the interconnection of all things and human-computer interaction in all aspects of the power system. It has the characteristics of comprehensive state perception, efficient information processing, and convenient and flexible applications. The construction of the power Internet of Things often requires the integration of multi-system data. During data integration, some data cannot be integrated in real time due to data source system maintenance or downtime, network failure, sensor network interruption, etc., or some data is missing due to packet loss in network transmission. At this time, it i...
