A Video Security Access Solution Based on the State Grid's B-Interface Protocol

With the improvement of automation and intelligence in the power system, the demand for power grid security monitoring has increased. However, traditional monitoring systems face issues such as a large number of video terminals, inadequate security protection, and limited data processing capabilities. This paper proposes a video security access solution based on the State Grid's B-interface protocol, aiming to resolve these issues and provide a new approach for power grid security monitoring. The solution includes the development of a video security access module, innovation in protocol conversion technology, and the integrated application of security technologies. We comprehensively protect the secure access and data transmission of video services. It is applicable to scenarios such as transmission line monitoring, safety supervision and infrastructure, substation video monitoring, and distribution video monitoring, where there are significant needs for video access and data encryption.
