Description

Technical Field

[0001] The present invention belongs to the technical field of wireless communications, and in particular relates to a forest area self-organizing network communication system based on unmanned aerial vehicles (UAVs). Background Art

[0002] When a forest fire or other emergency occurs in a forest area, a large number of ground workers are usually required to work together to respond. This collaborative work among ground workers across the forest area relies on an effective dispatch and command system. Currently, however, most ground workers in forest areas still collaborate using walkie-talkies, a method that is not suitable for emergency situations. The information it can convey is limited, and poor communication can easily lead to inadequate dispatch of ground personnel, resulting in casualties or property damage. Therefore, a more efficient forest operation networking system is urgently needed. Summary of the Invention

[0003] The purpose of the present invention is to provide a forest area self-organizing network communication system based on drones to solve the above-mentioned problems existing in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] The present invention provides a forest area self-organizing network communication system based on unmanned aerial vehicles (UAVs), comprising a UAV, a UAV remote control, a sky terminal and several ground terminals. The UAV establishes a UAV data transmission connection with the UAV remote control. The sky terminal is mounted on the UAV, establishes a signal connection with the UAV, and establishes a wireless communication connection with each ground terminal. The ground terminal is provided with a positioning module for receiving positioning information. The ground terminal is used to send the positioning information to the sky terminal and receive the command information sent by the sky terminal. The sky terminal is used to transmit the positioning information to the UAV and receive the command information transmitted by the UAV and send the command information to the ground terminal. The UAV is used to send the positioning information to the UAV remote control and receive the command information sent by the UAV remote control and transmit the command information to the sky terminal. The UAV remote control is used to receive the positioning information and send the command information to the UAV.

[0006] When it is used, ground workers carry ground terminals to perform corresponding operations in the forest area. UAV operators can control the drone to fly above the forest area through the drone remote control, so that the sky terminal on the drone and the ground terminal carried by the ground workers can establish a stable wireless communication connection. When the ground workers are working in the forest area, the ground terminals they carry can obtain positioning information in real time through the positioning module and send the positioning information to the sky terminal. The sky terminal then transmits the positioning information to the drone. The drone sends the positioning information of each ground terminal to the drone remote control through the digital transmission channel. The positioning information of each ground terminal and the corresponding ground workers are displayed to the drone operator through the drone remote control. The drone operator can use the drone remote control to send corresponding command information to the drone. The drone transmits the command information to the sky terminal, and the sky terminal then sends the command information to the corresponding ground terminal to dispatch and command the corresponding ground workers.

[0007] In one possible design, the sky terminal establishes a LoRa wireless network connection with each ground terminal.

[0008] In one possible design, the sky terminal includes a first microcontroller, a drone interface and a first LoRa transparent transmission module. The first microcontroller is connected to the drone interface and the first LoRa transparent transmission module respectively. The drone interface is used to establish a signal connection with the drone, and the first LoRa transparent transmission module is used to establish a LoRa wireless network connection with various ground terminals.

[0009] In one possible design, the first microcontroller is further connected to a first status indicator light and a first control button.

[0010] In one possible design, the first microcontroller adopts an STM32F405RGT6 microcontroller, the drone interface adopts a Type-C interface, and the first LoRa transparent transmission module adopts a GC433-TC018 LoRa transparent transmission module.

[0011] In one possible design, the ground terminal includes a second microcontroller and a second LoRa transparent transmission module, the second microcontroller is connected to the second LoRa transparent transmission module, and the second LoRa transparent transmission module is used to establish a LoRa wireless network connection with the sky terminal.

[0012] In one possible design, the second microcontroller is further connected to a second status indicator light and a second control button.

[0013] In one possible design, the second microcontroller adopts an STM32G070RBT6 microcontroller, and the second LoRa transparent transmission module adopts a GC433-TC018 LoRa transparent transmission module.

[0014] Beneficial effects: The present invention can quickly build an operational communication network in forest areas to achieve efficient positioning and tracking of ground workers and precise dispatch and command, improve the efficiency and safety of ground workers' operations in forest areas, eliminate the situation where ground personnel are not dispatched in place due to poor communication, reduce casualties or property losses, and is suitable for scene operations when forest fires or other emergencies occur in forest areas.

The specific structural and functional details disclosed herein are merely intended to describe exemplary embodiments of the present invention. However, the present invention may be embodied in a variety of alternative forms, and should not be construed as being limited to the embodiments set forth herein.

[0030] Example:

[0031] This embodiment provides a forest area self-organizing network communication system based on drones, such as Figure 1 As shown, it includes a drone 1, a drone remote controller 2, a sky terminal 3 and several ground terminals 4. The drone 1 establishes a drone data transmission connection with the drone remote controller 2. The sky terminal 3 is mounted on the drone 1, establishes a signal connection with the drone 1, and establishes a wireless communication connection with each ground terminal 4. The ground terminal 4 is provided with a positioning module for receiving positioning information. The ground terminal 4 is used to send the positioning information to the sky terminal 3 and receive the command information sent by the sky terminal 3. The sky terminal 3 is used to transmit the positioning information to the drone 1 and receive the command information transmitted by the drone 1, and send the command information to the ground terminal 4. The drone 1 is used to send the positioning information to the drone remote controller 2 and receive the command information sent by the drone remote controller 2, and transmit the command information to the sky terminal 3. The drone remote controller 2 is used to receive the positioning information and send the command information to the drone 1.

[0032] In specific implementations, ground workers carry ground terminals 4 while performing tasks within a forested area. A drone operator controls drone 1 via drone remote control 2, allowing drone 1 to fly above the forested area. This allows drone 1's sky terminal 3 to establish a stable wireless communication connection with the ground terminal 4 carried by the ground worker. Sky terminal 3 can then establish a LoRa wireless network connection with each ground terminal 4. While each ground worker is working within the forested area, their ground terminal 4 uses a positioning module (which can be a Beidou or GPS module) to obtain real-time positioning information and transmit it to sky terminal 3. Sky terminal 3 then transmits this positioning information to drone 1, which then transmits the positioning information from each ground terminal 4 to drone remote control 2 via a digital transmission channel. This information is then displayed to the drone operator via drone remote control 2, indicating the positioning information of each ground terminal 4 and the corresponding ground worker. The drone operator can then use drone remote control 2 to send command information to drone 1, which then transmits this information to sky terminal 3, which then sends this information to the corresponding ground terminal 4 to coordinate and direct the ground workers.

[0033] Furthermore, the sky terminal 3 includes a first microcontroller, a drone interface and a first LoRa transparent transmission module. The first microcontroller is connected to the drone interface and the first LoRa transparent transmission module respectively. The drone interface is used to establish a signal connection with the drone 1, and the first LoRa transparent transmission module is used to establish a LoRa wireless network connection with each ground terminal 4. The first LoRa transparent transmission module can receive the positioning information sent by the ground terminal 4, and then transmit the positioning information to the first microcontroller, which transmits the positioning information to the drone 1 through the drone interface. For example, the drone 1 can be a DJI drone, and the signal docking application between the drone 1 and the mounted sky terminal 3 is realized through the PSDK development toolkit. The first microcontroller can be used as follows Figure 2 and Figure 3 The STM32F405RGT6 microcontroller shown in the figure; the drone interface can be used as shown in the figure. Figure 4 The Type-C interface shown; the first LoRa transparent transmission module can be used as shown Figure 5 The GC433-TC018 LoRa transparent transmission module shown.

[0034] The ground terminal 4 includes a second microcontroller and a second LoRa transparent transmission module, the second microcontroller is connected to the second LoRa transparent transmission module, and the second LoRa transparent transmission module is used to establish a LoRa wireless network connection with the sky terminal 3. The second microcontroller can be used as follows Figure 6 The STM32G070RBT6 microcontroller shown in the figure, the second LoRa transparent transmission module can be used as shown in the figure. Figure 5The GC433-TC018 LoRa transparent transmission module shown.

[0035] The first microcontroller can also be connected to a first status indicator light and a first control button; the first status indicator light can indicate the working status of the sky terminal 3, such as the operating status, network status, power status, etc.; the first control button can be used to control the working status of the first microcontroller. The second microcontroller can also be connected to a second status indicator light and a second control button; the second status indicator light can indicate the working status of the ground terminal 4, such as the operating status, network status, power status, etc.; the second control button can be used to control the working status of the second processor. The first status indicator light and the second status indicator light can both be used as follows Figure 7 The LED indicator light, the first control button and the second control button can be used as shown in the following example: Figure 8 At the same time, the first microcontroller and the second microcontroller are also configured with corresponding peripheral circuits, such as a crystal oscillator circuit, a burning interface circuit, a debugging interface circuit, etc.

[0036] The sky terminal 3 and the ground terminal 4 can also be equipped with corresponding power modules for power supply. The power modules include: Figure 9 The first power conversion circuit shown and Figure 10 The second power conversion circuit shown; the first power conversion circuit can input a 2.7V-28V (such as 12V) power supply for power conversion, output a 5V power supply, and an operating current of 200mA; the second power conversion circuit can input a 2.7V-28V (such as 12V) power supply for power conversion, output a 3.3V power supply, and an operating current of 500mA.
