Description
Technical Field
The invention belongs to the technical field of cross-region communication, and particularly relates to a cross-region safe interaction method and system based on a power exchange network.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
At present, an independent power exchange network is established in a national power grid, and comprises an administrative exchange network and a dispatching exchange network. According to the characteristics of the electric power secondary system, the data communication network is divided into a production control large area and a management information large area, the production control large area is divided into a control area, namely a safety area I, and a non-control area, namely a safety area II, the information management large area is divided into a production management area, namely a safety area III, and a management information area, namely a safety area IV, safety protection is carried out between different network large areas through isolating devices, and the transmission rate is limited. As means for supporting important business such as administrative office and power grid dispatching, the power exchange network is independently networked, and along with the continuous advancement of digital transformation of companies, the safety interaction of the power exchange network, a production control area and a management information area is urgent.
The problems that exist are specifically analyzed as follows:
firstly, the information security interaction between the power exchange network and other network areas easily causes network congestion. The power exchange network is interconnected and communicated with the production control area and the management information area through a network isolation device special for power, and the device realizes information cross-area interaction in a read-write mode, however, because the power exchange network needs to transmit a large amount of media information, the information packets are more, the occupied bandwidth is larger, and network congestion at two ends of the isolation device is easy to cause.
And secondly, the call signaling negotiation across the network large area is difficult. The two users need to carry out call signaling negotiation at first, so that the IP address of the opposite party, media coding and decoding formats of the opposite party and the like are clear, the real-time requirement is high, and the signaling negotiation failure of the two parties of the call is easy to cause when a high concurrent call scene is encountered due to the limited transmission rate of the isolation device arranged between the power exchange network and other network areas.
Third, the user talk experience across the network area is poor. The voice between users is converted into RTP media stream for transmission, and due to the limited transmission rate of the isolation device, when a large number of users in different network areas talk, because the media message transmission is not timely, the conversation is intermittent, and the user experience is affected.

To achieve the above object, one or more embodiments of the present invention provide the following technical solutions: the method for safely interacting across the area based on the power switching network comprises the following steps:
acquiring data to be transmitted and classifying the transmitted data into media data and other data;
the media data is transmitted to an opposite terminal network after analog-digital conversion is carried out;
and caching and isolating the other data and transmitting the other data to an opposite-end network.

The one or more of the above technical solutions have the following beneficial effects:
the invention classifies the data flow to be transmitted, including signaling data, media data, management data, etc., and then formulates different cross-region interaction schemes according to the classification type. For media data, adopting a stripping media data protocol, converting the stripping media data protocol into an analog signal, transmitting the analog signal to an opposite terminal, converting the audio analog signal into a digital signal by the opposite terminal, repackaging the digital signal into an RTP media data stream, and transmitting the RTP media data stream into another network area; for signaling data and management data, a channel control scheduling algorithm is utilized to control on-off of buffers of different network areas while keeping physical isolation between two network areas, so that safe interaction between the power switching network and other network areas is realized.

detecting whether data exist in a queue of current storage state acquisition data and recording data or not at intervals of a time period;
if only one of the queues has data, transmitting the data in the queue in the current time period;
if the two queues have data, the data in the data queue is collected in the storage state in the current time period, and the data in the recording data queue is transmitted and stored in the next time period.
9. The power switching network-based cross-zone secure interactive system according to claim 5, further comprising an external network proxy and an external network portal; the external network proxy host is connected with the external network and the external network port respectively; the external network proxy host is used for carrying out decryption recombination posterior on data transmitted by an external network port and transmitting the data to the external network, and is also used for encrypting the data transmitted by the external network, stripping a protocol and transmitting the data to the external network port; the external network port is connected with the external network data processing module.
10. The power switching network-based cross-region secure interactive system according to claim 5, further comprising an intranet data reorganizing module, wherein the intranet data reorganizing module is configured to receive data of the external network digital-to-intranet analog-to-digital conversion module and the intranet data buffer module, perform protocol reorganization, and then transmit the data to the intranet.
