Data access method for communication gateway machine of electric power auxiliary equipment

Abstract

The invention relates to a data access method for a communication gateway machine of electric power auxiliary equipment, which comprises the following steps: when the communication gateway machine of the auxiliary equipment receives real-time data, judging whether the current data volume or data backlog time reaches a set threshold value; if the judgment result is yes, compressing the current data and transferring the current data to a background storage server; when the auxiliary equipment communication gateway machine receives the retrieval instruction, compressing the current data and transferring to a background storage server, and then sending a query retrieval command; after the background storage server receives the query retrieval command, compressing and segmneting the retrieved data, and then forwarding the data to the auxiliary equipment communication gateway machine; and decompressing the data and performing integrity verification by the auxiliary equipment communication gateway machine, and finally feeding back the data to a retrieval party. According to the method, the problem of insufficient storage capacity of the communication gateway machine of the auxiliary equipment is effectively solved; and the data retrieval task is allocated to the background storage server, so that the real-time data communication performance of the auxiliary equipment communication gateway machine is improved.

Description

technical field [0001] The invention relates to the technical field of substation auxiliary equipment automation, in particular to a data access method for a communication gateway of electric auxiliary equipment. Background technique [0002] The power technology is changing with each passing day, and the operation is becoming more and more intelligent. The auxiliary equipment communication gateway, as the intermediate link of data transmission in the substation, carries a large amount of data collection and forwarding work. In order to improve its data processing speed, the auxiliary device communication gateway generally adopts an embedded device, which has a relatively fast data processing speed but a small storage capacity. These characteristics determine that there will be certain restrictions on historical data retrieval. The drawbacks of its weak storage capacity come to the fore when this historical data needs to be accessed for troubleshooting and predictive analys...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the data access problem of the auxiliary equipment communication gateway, a large-capacity storage medium can be added to the auxiliary equipment communication gateway, which can solve the storage limitation of the auxiliary equipment communication gateway, but at the same time also reduce the gateway itself Acquisition and forwarding capabilities, resulting in a decline in its collection and forwarding capabilities
