The invention discloses an electric transmission line monitoring communication system based on a super-distance wireless optical network. The system comprises a wireless private network communication sub-network or a wireless private network and optical fiber mixed communication sub-network, a super-distance optical fiber communication backbone network, a monitoring primary station and a system network manager. The super-distance wireless optical network is characterized in that the wireless private network and optical fiber mixed communication sub-network wirelessly converges monitoring nodes of a plurality of nearby towers in a transmission line, an OPGW (optical fiber composite overhead ground wire) optical fiber communication system realizes uplink of the multiple nodes wirelessly converged, the optical fiber convergence nodes are connected to a transformer substation through an ADSS (all-dielectric self-supporting optic fiber cable), the wireless communication sub-network converges nodes of a plurality of nearby towers from node to multiple nodes, convergence signals are transmitted to the transformer substation by a wireless node-to-node manner, and data transmission between the transformer substation and a power company headquarter is performed through the existing data networks.

The invention provides an intelligent front-end multimedia information acquisition system used for accurately monitoring power station equipment. The system comprises a plurality of groups of data acquisition devices arranged in a production area I. The data acquisition devices are connected with equipment systems in the production area I. The data acquisition devices are further connected with anintelligent front-end data server arranged in a production area II through a first one-way safety isolation device. The intelligent front-end data server is connected with a second one-way safety isolation device. The second one-way safety isolation device is connected with a cloud server arranged in a management information large area through a private network. The system does not perform the simple lossy compression on acquired real-time data, wherein the sampling frequency and the data compression are dynamically adjusted according to actual needs. Meanwhile, data acquired in real time arestored in a structured database, while data not acquired in real time are stored in a non-structured database. Moreover, the data acquired by the system has the advantages of accuracy, integrity andconsistency. The system is safe in data transmission and high in efficiency. The same coding rule is adopted, and the data application is more efficient, more convenient and more purposeful.

The invention relates to a distributed multi-branch VPN communication method and system, and a storage medium, and the method comprises the following steps: detecting the communication quality of each transit server, and calculating the link communication quality between different transit servers; responding to communication joining of the first terminal and the second terminal, searching a plurality of paths with the best communication quality between the first terminal and the second terminal according to the link communication quality between the different transit servers, and establishing a plurality of branches; and realizing the transmission mode of the plurality of branches as a VPN layer, and transmitting a link layer data packet on the VPN layer to realize communication between the first terminal and the second terminal. The multi-branch communication and the VPN layer are combined to ensure that a point-to-point communication link is not influenced by a single-point fault, ensure that the network redundancy bandwidth is fully utilized, and ensure that when a certain communication link section fails, redundancy switching can be performed without communication link breakage at all.
