Embodiment Construction

[0033] Embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, various embodiments in the present application and various features therein can be combined arbitrarily with each other.

[0034] As mentioned above, in the smart energy ring network management system, SCADA data usually needs to be transmitted remotely. There are many uncertain factors in the transmission process, such as long network delay, network interruption, too many jumps, communication equipment Restart and so on cause data packet loss.

[0035] However, in the smart energy ring network management system, when there is no response to the SCADA data request, the request will be resent several times (generally 3 times). Request access again after the loop. Generally speaking, the reasons for the non-response of data requests are complicated. It may be restored after retrying in a short period...

Abstract

The invention discloses a data backfilling method, device and system. In one embodiment of the invention, the data backfilling method can comprise the following steps: when communication with a masterstation is interrupted, carrying out local data monitoring; and when it is monitored that there is a change in local data, generating a record for the changed data, and storing the record SCADA in apreset cache pool, so that the master station can obtain the changed data from the cache pool after communication is recovered. According to the embodiment of the invention, backfilling of the data collected by the SCADA can be realized, and data discontinuity caused by packet loss and the like is avoided.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data backfilling method, device, and system. Background technique [0002] In the smart energy ring network management system, the data of the Supervisory Control And Data Acquisition (SCADA) usually needs to be transmitted remotely, and there are many uncertain factors in the transmission process, such as long network delay, network interruption, Too many jumps, restart of communication equipment, etc. cause data packet loss. Contents of the invention [0003] In order to ensure the reliability of data transmission, the embodiment of the present application expects to provide a data backfill method, device, and system applicable to a smart energy ring network management system. [0004] According to one aspect of the present application, a data backfilling method is provided, including: [0005] When the communication with the master station is interr...
