ABSTRACT

Due to the unidirectional isolation characteristics of state grid secure access platform, it is an important research problem of the full tracking of transmission line. Furthermore, it is crucial for full tracking transmission line to be succeeded to transfer the data of video monitoring network to the internal network smoothly. In this paper, we analyze the structure of the secure access platform and the characteristics of the video data transmission process and propose a new method to solve the problem of the internal and external video data exchanging, which can ensure the video data crossing through the safety access platform. We deploy an intranet server and an extranet server, moreover, the extranet server sends the UDP heartbeat packets to the intranet server to maintain the network connection via SIP port. So the video inviting command could be transferred through the secure access platform. The experimental results show that the method can solve the problem of secure platform isolation effectively, and ensure the data of video arriving monitoring at the internal network successfully.
