[0008] A second direction power grid is composed of at least two second direction power grid rails, both of which extend along a second direction of a horizontal plane and have no intersections with each other;

[0009] Among them, the first direction power grid rail and the second direction power grid rail are both used for the aircraft to obtain power in the air. The first direction power grid rail and the second direction power grid rail are erected in the air. The first direction power grid and the second direction power grid are arranged in layers up and down in the height direction. The first direction power grid rail and the second direction power grid rail form a 3D power grid grid with intersections, and the projection of the 3D power grid on the horizontal plane is in a grid shape.

[0010] In some embodiments, optionally, the first-direction power grid rail and the second-direction power grid rail are both whole-section or segmented power grid rails.

[0011] In some embodiments, optionally, the first direction power grid line rail and the second direction power grid line rail are AC power grid line rails or DC power grid line rails.

[0012] In some embodiments, optionally, the low-altitude line-track type 3D power grid aircraft operation network system also includes a take-off and landing platform, and the take-off and landing platform is located near the first direction power grid line track and the second direction power grid line track.

[0014] In some embodiments, optionally, the low-altitude wire-track type 3D power grid aircraft operation network system also includes an aircraft, which flies along a first direction power grid track or a second direction power grid track to obtain power, and during the flight, changes the flight direction in the following manner: specifically: switching to another direction power grid track at the intersection of the first direction power grid track and the second direction power grid track to obtain power, and flying along the other direction power grid track.

[0015] In some embodiments, optionally, the first direction power grid rails, the second direction power grid rails and the communication cables are all erected in the air through power grid towers, and the communication cables below the first direction power grid rails and the second direction power grid rails have color markings set at equal intervals, which are used as flight references in the first direction and the second direction, and color markings are provided at different heights of the power grid towers, which are used as flight references in the height direction.

[0016] In some embodiments, optionally, the first direction and the second direction are two directions perpendicular to each other.

[0017] In some embodiments, optionally, a low-altitude linear track type 3D power grid aircraft operation network system also includes a take-off and landing platform, a power grid tower monitoring electronic eye, a power grid tower communication receiving transmitter and a background management station. The take-off and landing platform is set on the ground or on the roof of a building. The take-off and landing platform is equipped with a power supply control system, a gravity sensing device, a monitoring system, a charging system and a communication system.

[0026] like Figure 1 and 2 As shown, a low-altitude linear track type 3D power grid aircraft operation network system includes:

[0027] A first-direction power grid is composed of at least two first-direction power grid rails 1, and the first-direction power grid rails 1 extend along a first direction of a horizontal plane and have no intersections with each other;

[0028] The second direction power grid is composed of at least two second direction power grid rails 2, and the second direction power grid rails 2 extend along the second direction of the horizontal plane and have no intersections with each other;

[0029] Among them, the first direction power grid track 1 and the second direction power grid track 2 are both used for the aircraft to obtain power in the air. The first direction power grid track 1 and the second direction power grid track 2 are erected in the air. The first direction power grid and the second direction power grid are arranged in layers up and down in the height direction. The first direction power grid track 1 and the second direction power grid track 2 form a 3D power grid grid with an intersection, and the projection of the 3D power grid on the horizontal plane is in a grid shape.

[0030] The aircraft flies along the first direction power grid rail 1 or the second direction power grid rail 2 to obtain power, and during the flight, changes the flight direction in the following manner: specifically: switching to the other direction power grid rail at the intersection of the first direction power grid rail 1 and the second direction power grid rail 2 to obtain power, and flies along the other direction power grid rail.

[0031] The aircraft is generally an unmanned aircraft, but may be a manned aircraft, especially a manned aircraft with an automatic driving function.

[0032] The first-direction power grid line rail 1 and the second-direction power grid line rail 2 are erected in the air through the power grid tower 3. According to the ground power grid policy, low-altitude planning requirements and actual terrain conditions, the height and spacing of the first-direction power grid line rail 1 and the second-direction power grid line rail 2, the position and number of the power grid tower 3, and the specific routing of the first-direction power grid line rail 1 and the second-direction power grid line rail 2 extending in the first direction and the second direction are designed. Preferably, the first-direction power grid line rail 1 and the second-direction power grid line rail 2 extend in a straight line along the first direction and the second direction, and each first-direction power grid line rail 1 of the first-direction power grid is arranged parallel to each other, and each second-direction power grid line rail 2 of the second-direction power grid is also arranged parallel to each other, forming a rectangular 3D power grid grid. However, according to actual conditions, the first-direction power grid line rail 1 and the second-direction power grid line rail 2 may need to extend in a winding manner along the first direction and the second direction, and each first-direction power grid line rail 1 and each second-direction power grid line rail 2 are not arranged completely in parallel, but are only arranged roughly in parallel.

[0033] The first direction grid track 1 and the second direction grid track 2 are collectively referred to as grid tracks. The grid tracks extend in a straight line, and the grid towers 3 are also arranged in a straight line. The grid towers 3 of the first direction grid track 1 are designed to be as high as possible, and the grid towers 3 of the second direction grid track 2 are also designed to be as high as possible. That is, the plane where the first direction grid and the second direction grid are located is parallel to the horizontal plane, but there is a height difference between the two.

[0034] The first-direction grid rail 1 and the second-direction grid rail 2 are AC grid rails, more specifically single-phase AC grid rails, and the two parallel rails of the single-phase AC grid rail are the live wire 4 and the neutral wire 5, respectively. According to the design requirements, high-voltage power can be transmitted, and low-voltage power can also be transmitted. Because the grid rails are not suitable for long-distance suspension or in order to match the grid load and ensure grid load balance, the first-direction grid rail 1 and the second-direction grid rail 2 are disconnected after extending a certain length to become segmented grid rails. When the aircraft encounters a segment during continuous operation, it can jump over the segment and continue to fly along the grid rail to draw power.

[0035] The first direction grid track 1 and the second direction grid track 2 can also be DC grid tracks, which are determined according to the power consumption properties of the aircraft. The two parallel tracks of the DC grid track are respectively the positive line and the negative line, and the voltage is selected according to the design requirements.

[0036] The first direction and the second direction are two directions perpendicular to each other, namely the longitudinal direction and the transverse direction. The intersection height of the first direction grid line track 1 and the second direction grid line track 2 is a planned and designed safe height. The intersection point can be suspended from each other or located on tower heads of different heights of the same grid tower 3.

[0037] The low-altitude line-track type 3D power grid aircraft operation network system also includes a take-off and landing platform 7, which refers to a special platform for designated take-off or landing provided for the aircraft. The take-off and landing platform 7 is located near the first direction power grid line track 1 and the second direction power grid line track 2, and is preferably arranged around the power grid tower 3, so as to facilitate the work and operation of various monitoring and communication facilities.

[0038] The take-off and landing platform 7 is set on the ground or on the roof of a building. The take-off and landing platform 7 is equipped with a power supply control system, a gravity sensing device, a monitoring system, a charging system and a communication system. The power supply control system is connected to the gravity sensing device, the monitoring system, the charging system and the communication system to power and control them. The gravity sensing device is set on the take-off and landing platform 7 to sense the take-off and landing of the aircraft. The monitoring system is used to monitor the position and working status of the take-off and landing platform 7. The charging system is used to charge the aircraft. The communication system is a wired and 5G communication system, and the monitoring system at least includes electronic eye monitoring and position monitoring.

[0039] The low-altitude line-track type 3D power grid aircraft operation network system also includes a communication cable 6, a power grid tower monitoring electronic eye 8, a power grid tower communication receiving and transmitting device 9 and a background management station.

[0040] There are communication cables 6 in the slightly lower space below the first direction power line rail 1 and the second direction power line rail 2. The communication cables 6 are erected in the air together with the first direction power line rail 1 and the second direction power line rail 2. The communication cables 6 are specifically located between the two lines of the power line rails and are relatively parallel and independent to the two lines of the power line rails.

[0041] The communication cable 6 is different from the power grid line rail, is not a bare cable, and has an outer insulating layer with a higher insulation grade. Since the rigidity of the communication cable 6 is not large, it needs to be hung by a high-strength suspension cable during installation.

[0042] The communication cable 6 is used to connect and communicate information between the power grid tower monitoring electronic eye 8, the power grid tower communication receiving transmitter 9, the take-off and landing platform 7 and the background management station in a wired manner.

[0043] The power grid tower monitoring electronic eyes 8 are installed in different directions of the top, waist and base of the power grid tower 3. The power grid tower monitoring electronic eyes 8 are used to obtain monitoring data around the power grid tower 3 and transmit the monitoring data to the background management station. After the background management station analyzes and processes the received data, it makes correct operation and management instructions to ensure the safety and reliability of the entire system operation.

[0044] The power grid tower communication receiving and transmitting device 9 is arranged on the power grid tower 3, and can be installed on the top of the power grid tower 3, and can transmit satellite communication data, real-time flight feedback data of aircraft, meteorological environment data, take-off and landing platform feedback data and other big data generated during the operation of the entire power grid. The big data is transmitted to the background management station through the communication cable 6 for analysis and processing, and correct operation and management instructions are made to ensure the safety and reliability of the entire low-altitude flight. The background management station is actually the operation management and operation center of the entire system.

[0045] The communication cables 6 below the first direction power grid line rail 1 and the second direction power grid line rail 2 are provided with color marks arranged at equal intervals, which are called line rail color marks and are used as flight references in the first direction and the second direction. There are color marks at different heights of the power grid tower 3, which are called height color marks and are used as flight references in the height direction.

[0046] There are also color marks on the landing platform 7. The color marks on the landing platform 7 are letter-type color marks with a reflective function. Different letter-type color marks are set on different landing platforms 7 to allow the aircraft to distinguish which landing platform 7 it is parked on. Different letter-type color marks at different positions on the same landing platform 7 are used to allow the aircraft to identify the position of the landing platform 7 on which it is parked. For example, Figure 1 In the figure, the letter-shaped color markings on the landing platform 7 near the middle power grid tower 3 are C1 and C2, and the landing platform 7 is landing platform C. The letter-shaped color markings on the landing platforms 7 near the power grid towers 3 at the four corners are A1 and A2, B1 and B2, D1 and D2, E1 and E2, and the landing platforms 7 are landing platform A, landing platform B, landing platform D, and landing platform E. If the aircraft recognizes the letter-shaped color marking C1 when parked, it means that the aircraft is parked at the C1 position of the landing platform C near the middle power grid tower 3. In order to show the letter-shaped color markings on the landing platform 7 Figure 1 The take-off and landing platform 7 drawn in the figure is the front side of the take-off and landing platform 7.

[0047] Assume that the aircraft parked at position A1 of landing platform A receives a flight plan, and the destination is position E2 of landing platform E. The background management station issues a flight command to the aircraft and gives a flight path. The aircraft identifies the height color mark on the power grid tower 3, flies upward along the power grid tower 3 to the second direction power grid line track 2, and then flies to the position of the power grid tower 3 near the landing platform C along the second direction power grid line track 2 by identifying the line track color mark, and then descends to the first direction power grid line track 1 by identifying the height color mark and the line track color mark, and then flies to the position of the power grid tower 3 near the landing platform E along the first direction power grid line track 1, and then lands at the E2 position of the landing platform E by identifying the height color mark and the letter color mark E2 of the landing platform E, completing a flight process.

[0048] Specifically, the color mark on the communication cable 6 is installed on the suspension cable for hanging the communication cable 6. The color mark is in the shape of a strip and is made of ultra-light aviation aluminum profile. The surface is coated with a reflective fluorescent powder with strong adhesion. There are two conventional colors, silver and orange. When installing, the color mark is installed on the suspension cable at equal intervals according to the designed spacing. The color marks at different heights of the power grid tower 3 refer to the reflective fluorescent powder with strong adhesion applied at different heights of the power grid tower 3. There are two conventional colors, silver and orange. The color mark on the landing platform 7 is also a reflective fluorescent powder with strong adhesion applied on the landing platform 7. Of course, the color marks on the communication cable 6, the power grid tower 3 and the landing platform 7 can also adopt other color mark processing modes, and the color of the color mark can also be determined according to actual requirements. The length of the color mark is selected according to the specific application.

[0049] The low-altitude line-track type 3D power grid aircraft operation network system of the present invention uses low-altitude flying aircraft as the flight or transportation unit, and the 3D power grid grid is the power source of the aircraft. The first direction power grid and the first direction power grid have a certain absolute height difference, that is, the first direction power grid and the first direction power grid are not in the same plane. Therefore, the first direction power grid and the first direction power grid and the vertical take-off and landing line of the take-off and landing platform 7 form a 3D network for aircraft flight. Various low-altitude aircraft can complete orderly take-off and landing, grab the power grid line rail for charging, one-way continuous flight, jump the power grid line rail breakpoint flight, change the power grid line rail in different directions to turn the flight, jump and avoid in flight, and other flight working modes in the 3D network under the operation of the background management station and the service monitoring of various security systems.

[0050] The entire 3D power grid aircraft operation network system provides a relatively safe and reliable operation system for low-altitude cargo and manned aircraft transportation; because of the design of direct power supply from the power grid, the aircraft can theoretically achieve unlimited endurance; the entire system has wired, wireless and satellite systems, which can work simultaneously or independently, and can ensure the safety and stability of the entire operation system. All monitoring big data obtained by the system can provide data supplements for the social management system and complement other flight routes without affecting special flight routes; although the entire system still requires some power grid infrastructure, the construction and maintenance costs are absolutely much lower than those of ground road systems and rail transit systems.
