Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
As shown in fig. 1, a fully-connected smart grid communication method is proposed, where the grid includes an above-ground power transmission line and an overhead line, and an underground cable, and the fully-connected smart grid communication method includes the following steps: in the area where underground cables are laid, parameter signals of an overground power transmission line or an overhead line are transmitted in a wireless communication mode to be monitored;
parameter signals of underground cables are transmitted based on a mode of combining PON communication and PLC communication for monitoring; laying optical fibers in a main network of the underground cable, transmitting parameter signals of the main network of the underground cable to the wireless communication on the ground for monitoring based on PON communication; parameter signals of a slave network of the underground cable are transmitted to a main network of the underground cable based on a PLC communication mode, and then transmitted to an above-ground wireless communication for monitoring based on PON communication.
Among them, wireless communication is simple to set up, and therefore transmission of parameter signals of a power transmission line and an overhead line on the ground is performed based on wireless communication. The effect of adopting a wireless network to communicate the parameter signals of the underground cable is poor, so that a PON and PLC combined mode is adopted for communication. Compared with an active system, the industrial PON communication network has the advantages of saving optical cable resources, sharing bandwidth resources, being high in network building speed, being low in comprehensive network building cost and the like. An optical network in the power industry generally adopts an EPON communication network, which is one type of industrial PON networks and is also a pure optical medium network, so that the electromagnetic interference and lightning influence of external equipment are avoided, the fault rate of circuits and the external equipment is reduced, the system reliability is improved, and the maintenance cost is saved. In areas where underground cables are laid, the laying of the underground cables comprises the forms of underground power cable tunnels, underground power cable direct burial, cable ducts, pipe banks and the like. The underground power cable tunnel is a main trunk of the underground cable, a main network of the underground cable is arranged in the underground power cable tunnel, optical fibers are laid in the main network, EPON communication is adopted, and parameter signals are transmitted to an overground wireless communication network. The underground power cable is directly buried, and the cable trench and the cable duct are slave networks of the underground cable, parameter signals of the slave networks are transmitted to a main network EPON communication network of the underground cable by local PLC power line carrier communication, and then the parameter signals are transmitted to an overground wireless communication network.
In one embodiment, in areas without underground cabling, the parameter signals of the power transmission lines or overhead lines on the ground are transmitted for monitoring based on wireless communication.
In the embodiment, in the area without underground cable laying, the parameter signal is directly transmitted in a wireless communication mode to be monitored. And selecting a proper communication mode according to the existence of the underground cable to build a corresponding communication network. When the system is used, the communication modes are deployed according to different specific application scenes so as to be suitable for use in various scenes. The requirement of low power consumption is guaranteed while the requirement of timely and smooth communication of different scenes is met, and the construction cost is reduced. The embodiment is based on the combination of a wireless network, a PON network and PLC communication, realizes the intelligent management of the whole power transmission network, and achieves the full coverage of the power transmission network communication network. The wireless network in this embodiment may be a 3G, 4G, or 5G communication network.
In one embodiment, the wireless communication transmits signals based on 5G communication.
Among them, 5G communication has advantages of low latency, high-speed communication, and the like. The wireless communication described in the present embodiment is therefore based on 5G communication transmission signals.
As shown in fig. 2, in one embodiment, the manner of transmitting signals in the 5G communication includes the following steps:
in an area covered by 5G signals, parameter signals of a power grid are directly transmitted by adopting 5G communication; and in the area without 5G signal coverage, a RIS phased array is built to carry out relay communication so as to transmit the parameter signal to the area with 5G signal coverage.
Because the power grid is widely distributed, if the full coverage of wireless network signals cannot be realized by simply depending on a 4G or 5G base station, the power grid cannot be monitored in all directions. Therefore, in the area where the 4G or 5G signals cannot cover, a phased array antenna is required to be used for expanding the network. The phased array antenna has the advantages of simple structure, high speed, small volume, 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, can be combined with a telecommunication 5G slice private network to carry out full network coverage, realizes the network coverage of a power transmission line corridor, and finally forms the intelligent full-connection network coverage of an overhead line and a full power transmission line channel of an underground cable. Generally, the area where underground cables are laid is an urban area, 5G signals are covered, the existing 5G network can be applied to achieve network coverage, and a phased array antenna expansion network is not needed.
In one embodiment, constructing the RIS phased array comprises the steps of: the RIS phased array antenna is arranged at an overhead line tower extended from the 5G tail end, and other RIS phased array antennas are arranged in other areas without 5G signal coverage according to the coverage distance of the RIS phased array antenna, so that wireless communication is realized in all the areas.
Wherein, the area without 5G signal coverage arranges a plurality of RIS phased arrays, makes the transmission of parameter signal through more than one RIS phased array can pass the signal to the area with 5G signal coverage.
In one embodiment, the RIS phased array antenna is a fixed phased array antenna or a mobile phased array antenna, including an onboard mobile phased array antenna; the RIS phased array antenna is accessed to the 5G network through the 5G gateway; the RIS phased array antenna establishes a wireless communication link with the monitoring equipment through microwaves; and in the movement process of the monitoring equipment, the antenna beams of the RIS phased array antenna automatically switch the angle so as to establish real-time communication connection with the monitoring equipment.
Monitoring equipment such as a monitoring camera and the like is connected to the wireless network bridge through the switch, and the wireless network bridge is connected with the wireless network to realize real-time return of monitoring data; in a wireless network, an RIS phased array antenna is connected with a 5G gateway of a 5G network through a switch to realize data access. The communication coverage distance of the RIS phased array antenna is related to the antenna model power and the like, and in the embodiment, the directional wave beam emitted by the antenna is selected to realize the wireless network coverage in the area within 20 kilometers of the visual distance. If a fixed phased array antenna is adopted, the RIS phased array antenna can be arranged on the top of the pole tower. The monitoring device is used for monitoring devices such as a camera, a sensor, a mobile terminal, an unmanned aerial vehicle and a robot, and can be used for acquiring parameter signals including but not limited to current signals, voltage signals, temperature signals or video signals. The monitoring equipment is connected with the RIS phased array through the switch and further connected with a 5G network and the like, real-time return and two-way communication of monitoring images, monitoring data and mobile terminal data are realized, and data access is realized. Particularly, when the monitoring facilities is for being used for the unmanned aerial vehicle that electric power patrolled and examined, because be in motion state during the unmanned aerial vehicle monitoring, consequently for better establishment wireless communication link, during the unmanned aerial vehicle flight, antenna beam automatic switch-over angle (switching speed 2 microseconds) remains throughout to establish real-time communication with unmanned aerial vehicle and is connected, realizes 5G network broadband interconnection and high-speed wireless data transmission. The model of the phased-array antenna is R1-C11-1, and the specific performances are as follows: antenna size: 500x400x470 mm; the weight of the antenna is 8.6 Kg; the power supply range is DC 9-36V; the temperature range is-40 to 85 ℃; the antenna frequency is 5.8GHz communication frequency band; the antenna gain is 18 dBi; the polarization mode is linear polarization; the standing-wave ratio is 1:3: 1; the input impedance is 50 omega; side lobe level: less than or equal to-15 dB; front-to-back ratio of 28 dB; the half-power beam width is less than or equal to 8.8 degrees. Unlike conventional phased array antennas, which use expensive TR elements to control the phase of the array elements, each element of an electromagnetic surface reflection array antenna has its own integrated phase modulation and radiation functions. Therefore, when the electromagnetic wave irradiates the entire surface, beam focusing and scanning can be achieved in space by controlling the phase of each element. In actual control, the control circuit board which takes the FPGA as a main control chip is adopted to carry out digital control on the PIN diode integrated on the reflection electromagnetic surface unit, so that the effect of controlling antenna beams is achieved. The antenna has the outstanding advantages of simple structure, low cost, light weight, low power consumption, high efficiency and the like.
