Intranet and extranet integrated power grid data communication system and method

Abstract

The invention discloses an internal and external network integrated power grid data communication system and method. The problems that in the prior art, a power grid independently uses a private network for communication, huge information amount interaction cannot be met, and data communication safety cannot be guaranteed when an external network is used are solved. The method comprises the following steps: S1, robot inspection: collecting power grid data; S2, encrypting the acquired power grid data; transmitting the encrypted power grid data to a cloud database through an external network, and transmitting a secret key to a control center through an internal network; S3, the control center obtaining the corresponding encrypted power grid data from the cloud database through the external network, decrypting the encrypted power grid data by using the secret key, and restoring the encrypted power grid data to obtain the original power grid data; and S4, the control center performing power grid fault diagnosis according to the original power grid data and judging whether the inspection object has a fault or not. Encrypted data is transmitted through the extranet, and a secret key is transmitted through the intranet, so that huge information interaction can be met, and meanwhile, the security of data transmission can be ensured.

Description

Technical field [0001] The present invention relates to a field of power grid data communication, and more particularly to an internal and external network fused grid data communication system. Background technique [0002] Currently, smart robots use private network communications. The special network refers to a secure and reliable professional network for a specific department or group (such as government affairs and public safety), which is independent of other communication networks. Intelligent Robots and Control Center constitute a local area network to implement mutual communication, isolated from the Internet, company information intranet, ensuring communication security of intelligent robots. [0003] However, as the grid is continuously expanded, the promotion of smart grid construction, power equipment, power terminal, user sharp increases, between equipment and equipment, equipment and users, the user and the user's information transfer interaction is burst out. Grow...

AI Technical Summary

Problems solved by technology

[0005] The present invention mainly solves the problem that the prior art power grid cannot meet the huge amount of information interaction by using private network communication alone, and cannot guarantee the security of data communication when using an external network; it provides a power grid data communication system that integrates internal and external networks, and transmits data through an external network. Encrypted data, the secret key is transmitted through the intranet, which can not only meet the huge amount of information interaction, but also ensure the security of data transmission
