Background
The Yunnan province is one of the nationwide provinces with the largest green power (hydroelectric power, wind power and photovoltaic) output, and is very urgent to the network construction of power transmission lines and cable tunnels after being overhead into the ground. But the coverage area of the power transmission line is wide, the terrain of the passing area is complex, the natural environment is severe, and great pressure is brought to the coverage of the communication network.
The Yunnan power grid company is responsible for power supply, power grid planning and construction, power grid operation, maintenance and management and other works in the jurisdiction. Most areas in Yunnan province are mountainous areas, forest coverage rate is high, terrains are complex, partial areas have no network coverage, and an operator network cannot comprehensively and effectively support power grid intelligent construction. Meanwhile, as the overhead lines of the urban area enter the ground, the operation and maintenance difficulty of the power grid on the underground wide cables is quite huge after the number of the cables is increased, and especially, early fault analysis is carried out on the daily maintenance, operation and maintenance and inspection work of the underground cables.
In the construction of a smart power grid, the different requirements of large bandwidth, low time delay, large connection, safety, reliability and isolation of application scenes such as power grid operation scheduling, power transmission line working condition monitoring, cable line working condition monitoring, smart inspection and the like can be met only by a communication network which stably operates for a long time. But because the field range of the power grid is wide, the power transmission line and the power transmission corridor need network coverage so as to carry out remote monitoring; meanwhile, after the overhead line of the urban construction transmission line enters the ground, the underground cable is linearly deployed, the line-along communication mainly depends on the underground optical network communication, and the underground cable and the overhead line are segmented, so that the wireless network and the wired network need to be connected. Therefore, network coverage of the channel corridors along the power grid main power transmission network and the cable tunnel after the power grid main power transmission network enters the ground at present seriously restricts the popularization of big data service for building the intelligent power grid in China.

In the embodiment, the data acquisition of the whole power transmission network is realized by combining the optical network with the wireless network and the phased array antenna connected in a multistage array mode, and a network foundation is provided for the comprehensive and timely acquisition of the routing inspection data of the power transmission network. Because the optical network needs to use optical fibers, it is difficult to separately adopt the optical network to realize the transmission of information of the transmission network in the air such as overhead lines of the transmission network, and the like. Because the power grid is widely distributed, if the pure dependence on a wireless network such as a 4G or 5G base station cannot realize the full coverage of wireless network signals in the area outside the optical network coverage area, the comprehensive monitoring of the power grid cannot be realized. Therefore, in the area where the 4G or 5G signals cannot cover, a phased array antenna is needed to expand the network. The phased array antenna has the advantages of simple structure, high speed, small size, intellectualization, low cost, light weight, low power consumption, high efficiency, long distance, large bandwidth, low time delay, mobility, beam scanning, beam forming and the like, is not the second choice for wireless network extension, and can be combined with a telecommunication 5G slice private network to carry out full network coverage.

The method adopts the phased array-based method to realize the aerial three-dimensional network coverage to provide stable, reliable and flexible individual communication support capability. The characteristics of no signal in power grid mountainous areas and interconnection and intercommunication of cable tunnel optical networks can be solved through the phased array antenna. The wireless network in this embodiment may be a 3G, 4G, or 5G communication network.
In one embodiment, the wireless network is connected with the monitoring center through a first path or a second path, wherein the first path is that the wireless network is connected with the monitoring center through a wireless private network, and the second path is that the wireless network is connected with the monitoring center through a ring network;

The monitoring coverage expansion and edge calculation functions are realized based on the fusion terminal, the existing power grid transmission line assets are in linear layout, and the problem of multiple optical distribution in the traditional PON is difficult to solve.
