[0043] like Figure 1 As shown, the embodiment of the present invention provides a communication range extension method, which is applied to Figure 2 The communication extended-range system 20 is shown.

[0044] Figure 2 In the embodiment, the communication range extension system 20 includes an operation control device 21, a controlled device 22, a signal repeater 23 and a buoyancy balloon 24. The operation control device 21 is connected to the controlled device 22 through the signal repeater 23, the buoyancy balloon 24 is arranged on the signal repeater 23, the signal repeater 23 is fixed on the ground through a height fixing line 25, and the operation control device 21 controls the suspension height of the buoyancy balloon 24 by adjusting the length of the height fixing line 25.

[0045] It should be noted that, in the embodiment of the present invention, the operation control device is a remote control device, which can remotely control the operation of the signal repeater 23 and remotely adjust the length of the height fixed line 25, wherein the height fixed line 25 may include a height fixed line body and a height fixed line length control device, and the operation control device adjusts the length of the height fixed line 25 by sending instructions to the height fixed line length control device.

[0046] Figure 1 The communication range extension method includes but is not limited to the following steps:

[0047] S101. The operation control device receives an extended range instruction.

[0048] The extended range instruction includes a preset height of the signal repeater. In a specific application, the preset height is the shortest distance between the signal repeater and the ground of a fixed height fixed line.

[0049] In a specific application, the range extension instruction is generated according to the application environment of the communication range extension system 20, that is, according to the location of the signal repeater and the surrounding obstacle information of the signal repeater, such as the height of the building where the signal repeater is located, the height of the building and the height of the trees that block the signal repeater, etc. If the height of the building where the signal repeater is located is A and the height of the building that blocks the signal repeater is B, the range extension instruction includes "adjusting the preset height of the signal repeater to BA".

[0050] It should be noted that the range extension instruction in the embodiment of the present invention is generated according to the application environment of the communication range extension system 20. In actual application, the operation control device periodically receives the range extension instruction. When the application environment of the communication range extension system 20 changes, the range extension instruction changes. According to the communication range extension method provided in the embodiment of the present invention, the communication range extension system 20 automatically changes the height of the signal repeater according to steps S101 to S104.

[0051] S102. Calculate the length of the fixed altitude line and the traction buoyancy value that the buoyancy balloon needs to achieve according to the extended range instruction.

[0052] In the above step S102, the length of the height fixing line is greater than or equal to the preset height.

[0053] In the above step S102, the traction buoyancy value that the buoyancy balloon needs to reach is greater than the sum of the gravity value of the signal repeater and the gravity value of the height fixed line.

[0054] It should be noted that the length of the fixed height line is greater than or equal to the preset height. Therefore, in an embodiment of the present invention, when calculating the gravity value of the fixed height line, the gravity of the fixed height line is calculated according to the preset height of the signal repeater in the extended range instruction as the length of the fixed height line.

[0055] In the above step S102, calculating the traction buoyancy value that the buoyancy balloon needs to achieve includes:

[0056] Get the reserved safety factor;

[0057] Towing buoyancy value = (mass of signal repeater + mass of height fixed line) x (1 + reserved safety factor).

[0058] The reserved safety factor is a natural number greater than 0 and less than 1. In one embodiment, the value of the reserved safety factor is 0.2.

[0059] In an embodiment of the present invention, a safety factor is reserved so that the traction buoyancy value that the buoyancy balloon needs to achieve must be greater than the gravity value of the signal repeater and the gravity value of the height fixing line, thereby ensuring that the buoyancy balloon can tow the signal repeater to the preset height required by the extended range instruction.

[0060] S103, inputting safety gas into the buoyancy balloon until the buoyancy of the buoyancy balloon reaches the traction buoyancy value.

[0061] In the above step S103, the safety gas is a gas having a density lower than that of air.

[0062] In the embodiment of the present invention, the traction buoyancy value is converted into a measurable radius of the buoyancy balloon to achieve accurate control of the traction buoyancy value, wherein the radius of the buoyancy balloon is obtained by measuring the circumference of the sphere of the buoyancy balloon.

[0063] It is understandable that the traction buoyancy value is a theoretical value, and therefore, it can be calculated before the above step S103, including: calculating the traction radius of the buoyancy balloon when the buoyancy of the buoyancy balloon reaches the traction buoyancy value.

[0064] In specific applications, first, set the traction buoyancy value to F 浮力 , then F 浮力 =(G 中继器 +G 固定线 )*(1+0.2 预留安全系数 ), where G 中继器 is the gravity of the signal repeater, G 固定线 is the gravity of the highly fixed line.

[0065] Then, F 浮力 It can also be expressed as, F 浮力 =ρ 空气 V 浮力气球 ;

[0066] Among them, V 浮力气球 =(4 / 3)πR 牵引 3.

[0067] Then we can calculate the traction radius of the buoyancy balloon when the buoyancy of the buoyancy balloon reaches the traction buoyancy value, that is, R in the above formula 牵引 .

[0068] The buoyancy of the buoyancy balloon in step S103 reaches the traction buoyancy value, including:

[0069] Measuring the circumference of the buoyancy balloon to obtain the current radius of the buoyancy balloon;

[0070] When the current radius of the buoyancy balloon reaches the traction radius, the buoyancy of the buoyancy balloon reaches the traction buoyancy value.

[0071] In a specific application, the circumference of the buoyancy balloon is measured, and the current radius of the buoyancy balloon is set as R 当前 ,

[0072] Where, C buoyancy balloon = 2πR 当前 , then when the measurement obtains C 浮力气球 Later, you can get R 当前 .

[0073] Then when R 当前 For the above R 牵引 , the buoyancy of the buoyancy balloon reaches the traction buoyancy value.

[0074] In the embodiment of the present invention, after the buoyancy of the buoyancy balloon reaches the traction buoyancy value, that is, inputting safety gas into the buoyancy balloon until the buoyancy of the buoyancy balloon reaches the traction buoyancy value, the method includes:

[0075] The input of safety gas into the buoyancy balloon is stopped, and the buoyancy balloon is sealed.

[0076] In the communication range-extending system 20 provided in the embodiment of the present invention, the buoyancy balloon further includes an air valve. In the embodiment of the present invention, the buoyancy balloon is sealed by closing the air valve.

[0077] S104. Towing the signal repeater to the preset height and fixing it by the buoyancy balloon.

[0078] In the above step S104, the process of the buoyancy balloon pulling the signal repeater to the preset height actually provides the buoyancy balloon with an upward force to increase the height of the signal repeater from the ground. At the same time, the height fixing line provides a downward pulling force to constrain the height of the signal repeater from the ground, thereby stabilizing and fixing the signal repeater at the preset height.

[0079] In the embodiment of the present invention, the structure of the communication range-extending system 20 is optimized to optimize the fixing effect in the above step S104.

[0080] Figure 2 In the embodiment, the communication range extension system 20 further includes a manual axle adjuster 26 and a buckle 27 for fixing the manual axle adjuster 26 . The manual axle adjuster 26 and the buckle 27 are arranged on the ground where the height fixing line 25 is fixed.

[0081] Based on this, in the above step S104, the signal repeater is towed to the preset height and fixed by the buoyancy balloon, including:

[0082] The length of the height fixing line is adjusted to the preset height by the hand-cranked axle adjuster so that the buoyancy balloon pulls the signal repeater to the preset height, and the hand-cranked axle adjuster is fixed by the buckle to fix the length of the height fixing line, i.e., the preset height.

[0083] Figure 2 In the embodiment, the communication range extension system 20 further includes a traction fixed line 28, one end of which is connected to the signal repeater 23 and the other end of which is fixed on the ground. In addition, the traction fixed line 28 includes multiple groups, which are used to stabilize the position of the signal repeater 23 suspended in the air, ensure that the signal repeater 23 can be suspended in the air to a preset height, and increase the stability of the communication range extension system 20.

[0084] It should be noted that the operation control device 21 described in the embodiment of the present invention can be a ground operator, and the controlled device 22 can be a drone, then the signal repeater is used to receive and forward the remote control signal of the ground operator, and receive and forward the image transmission signal of the drone. The operation control device 21 can also be a mobile terminal, and the controlled device 22 can be a host electronic device, then the signal repeater is used to receive and forward the control signal of the mobile terminal, and receive and forward the working status signal of the host electronic device. Through the embodiment of the present invention, the signal relay communicator is set on the shield between the ground operator and the drone flight area, or on the shield between the mobile terminal and the host electronic device area, and then the height of the suspended signal repeater is controlled by adjusting the hand-cranked wheel axle adjuster to reduce the blocking effect of obstacles such as buildings and mountains, and the assembly and disassembly is convenient and quick, the device is highly flexible, the equipment is convenient to maintain, and the equipment cost is low.
