Problems solved by technology

For the long-distance and high-altitude communication environment, it is obviously unable to meet the communication requirements
[0005] Foreign countries use over-the-horizon communication terminals to achieve communication. This communication method is also based on a limited communication range and cannot perform thousands of miles of high-altitude operations.
[0006] The control is generally a point-to-point control mode, which is difficult to achieve multiple access, communication, and monitoring, which increases the management of relevant departments

Embodiment 1

[0040] figure 1 It is a block diagram of the UAV communication system based on the 4G / 5G wireless network provided by this embodiment. like figure 1As shown, the drone communication system based on 4G / 5G wireless network includes multiple drones 1 , multiple wireless base stations 2 , IDC room 3 and multiple user terminals 4 . The UAV 1 and the wireless base station 2 are connected through a 4G / 5G wireless network, the wireless base station 2 and the IDC room 3 are connected through an optical fiber network, and the IDC room 3 and the user terminal 4 are connected through a wired / wireless network. Make a communication connection. The IDC computer room 3 can also be connected to the cloud. The use of 4G / 5G wireless network to realize air-to-ground data transmission is a special network completely different from the existing consumer-grade communication network; during network operation, multiple drones can be controlled simultaneously for multi-dimensional operations; drone-...

no. 1 example

[0049] According to the first embodiment of the present invention, the mission computer at the airborne end of the UAV will receive the control information from the flight controller, and at the same time transmit the command data from the command center to the flight controller. At the same time, the task computer completes the parameter control of the payload equipment and the processing and transmission of the payload data. The mission computer can also access the data of the RTK reference station, carry out precise repositioning processing on the GPS data, improve the accuracy of flight control, and ensure the safety of multiple aircraft operating in the air.

[0050] According to an embodiment of the present invention, the present invention provides that the onboard end of the UAV provides energy to each component by an energy device, which can be turned off and on by a switch, and the energy device includes at least a generator.

[0051] The UAV communication network bas...

Embodiment 2

[0053] This embodiment provides a 4G / 5G wireless network-based UAV communication method, which is applied to a user terminal, including the following steps: the ground control terminal of the user terminal repeatedly sends broadcast information on an idle channel, and waits for a response; the ground control terminal If the response signal sent by the wireless device on the drone's onboard side is received, a communication connection is established with the wireless device on the drone's onboard side, and the ground control terminal and the wireless device on the drone's onboard side enter the handshake authentication stage. If the ground control terminal does not receive the response signal sent by the wireless device on the drone's airborne terminal, it will reconnect.

[0054] According to an embodiment of the present invention, the working process of the ground end part includes:

[0055] S1-01: Access the information of multiple drones and establish a communication connec...

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle communication, in particular to a communication system and method for an unmanned aerial vehicle based on a 4G / 5G wireless network. Background technique [0002] As the application of drones becomes more and more widespread, the application scenarios are gradually increasing, and the use in public monitoring environments such as pipeline inspections and forest fire prevention is becoming more and more urgent. However, these operating environments are relatively harsh, and traditional station installation is difficult and maintenance costs are high, which poses great challenges to the normal operation of drones. The traditional UAV measurement and control is based on mobile ground communication terminals as the main means. This communication method has the characteristics of flexible construction and construction as it is used. However, due to the limitation of the visual condition...
