[0028] In view of the above-mentioned problems faced by different drone communication terminals in software development (faced with various complicated communication protocols, low terminal IP resource utilization, difficulty in automatic connection due to network interruption and poor communication quality), the present invention integrates 5G communication technology and proposes a 5G communication terminal software driver optimization method to meet the requirements of automatic adaptation of drone communication terminals to any type of communication protocols, high terminal IP resource utilization, automatic network reconnection, etc., to ensure high-speed and stable transmission of communication terminal data.

[0031] The method for optimizing the software driver of the drone 5G communication terminal of the present invention is a communication terminal driver program. In one embodiment of the present invention, the communication terminal driver program structure is as follows: Figure 2 shown.

[0032] See also Figure 2 The communication terminal driver includes a main control module, a network connection module and a serial port processing module; the main control module mainly realizes the communication protocol data processing; the network connection module mainly realizes the connection between the communication terminal and the 5G network signal, the communication protocol data is sent and received through the 5G network signal, and the 5G network signal status detection; the serial port processing module mainly realizes the data interaction between the communication terminal and the drone control terminal.

[0033] Now combined Figure 2 The main functions of each module are described in detail.

[0034] 1)Serial port processing module

[0035] (a) Create an image data sending function to receive and process the acquired camera image data in real time, and use RSTP streaming to send the camera image data to the server via the 5G network signal, and then display it on the ground control end to ensure that the ground control end monitors the environment around the drone and ensures the safety of the drone flight;

[0036] (b) Create a serial port RS232 transceiver function and a serial port RS422 transceiver function to meet the needs of the communication terminal to exchange data with the drone control end through the serial port RS232 or serial port RS422; specifically, the serial port RS232 transceiver function includes a serial port RS232 receiving function and a serial port RS232 sending function. The serial port RS232 receiving function is used to receive the downlink telemetry data sent by the drone control end to the communication terminal through the serial port RS232, and the serial port RS232 sending function is used for the communication terminal to send uplink remote control data to the drone control end through the serial port RS232; the serial port RS422 transceiver function includes a serial port RS422 receiving function and a serial port RS422 sending function. The serial port RS422 receiving function is used to receive the downlink telemetry data sent by the drone control end to the communication terminal through the serial port RS422, and the serial port RS422 sending function is used for the communication terminal to send uplink remote control data to the drone control end through the serial port RS422;

[0037] The serial port RS232 transceiver function sets a delay timer according to the data transmission frequency to transmit and receive data (uplink remote control data or downlink telemetry data) at the serial port RS232. Similarly, the serial port RS422 transceiver function sets a delay timer according to the data transmission frequency to transmit and receive data (uplink remote control data or downlink telemetry data) at the serial port RS422, that is, the prior art needs to abandon the reading method based on the communication protocol frame header, check code and protocol byte length, so that the communication terminal can adapt to the communication protocol data transmission and reception in any format;

[0038] The serial port RS232 receiving function and the RS422 receiving function realize receiving the downlink telemetry data sent from the drone control end to the communication terminal, and set up the telemetry data flag bit for the main control module to judge and process, and call the network port sending function in the main control module to send the downlink telemetry data to the ground control end; the serial port RS232 sending function and the serial port RS422 sending function realize sending the uplink remote control data obtained from the network port receiving function to the drone control end;

[0039] 2) Network connection module

[0040] (a) Using the TCP protocol to create a TCP network connection function to connect the communication terminal to the 5G network signal; setting a corresponding login number for each communication terminal to connect to the server to ensure the transmission and reception of remote control, telemetry, and image data between the communication terminal and the server;

[0041] (b) Creating a network port transceiver function, the network port transceiver function includes a network port receiving function and a network port sending function; the network port receiving function is used to receive the uplink remote control data sent by the ground control end to the communication terminal through the server and the 5G network signal, and set the remote control data flag; the network port sending function is used for the communication terminal to send the downlink telemetry data from the drone control end and the camera image data from the camera to the server through the 5G network signal;

[0042] (c) Create a 5G network signal status real-time detection function to determine the network signal quality by judging the network signal status parameters in real time. The judgment result is fed back to itself in real time for judgment and processing. When the communication terminal is disconnected from the 5G network signal due to 5G network signal problems (no 5G network signal), the 5G network signal status real-time detection function will send a connection instruction to the TCP network connection function after the 5G network signal is restored. The TCP network connection function reconnects the communication terminal to the 5G network signal to achieve automatic network reconnection;

[0043] 3) Main control module

[0044] (a) Create a thread function, and simultaneously start the serial port RS232 transceiver function, serial port RS422 transceiver function, network port transceiver function, and 5G network signal status real-time detection function to ensure that the communication protocol data between the communication terminal and the drone control terminal and the ground control terminal can be sent and received in real time, and continuously detect the 5G network signal in real time to ensure that the network signal can be searched after the network connection is interrupted until the network signal is restored, and then reconnect to the server;

[0045] (b) Create a terminal tag adding function to set a distinguishable terminal tag number for each communication terminal. When a communication terminal sends downlink telemetry data, the terminal tag number of the communication terminal is added to each downlink telemetry data packet using the terminal tag adding function. This is used by the ground control end to identify the downlink telemetry data sent by different communication terminals. This allows multiple communication terminals to share an IP address to connect to the server. The ground control end only needs to identify the data source based on the terminal tag number, which greatly reduces the use of IP addresses and improves the utilization rate of terminal IP resources.

[0046] (c) Create a communication protocol data processing function, and determine whether the communication protocol data is uplink remote control data from the ground control end to the UAV control end, or downlink telemetry data from the UAV control end to the ground control end according to the data flag bit of different communication protocol data. If the data flag bit is the remote control data flag bit, the communication protocol data processing function calls the serial port sending function (serial port RS232 sending function or serial port RS422 sending function) to transmit the communication protocol data (uplink remote control data) to the UAV control end. If the data flag bit is the telemetry data flag bit, the communication protocol data processing function calls the network port transceiver function to transmit the communication protocol data (downlink telemetry data) to the ground control end.

[0047] The drone 5G communication terminal software driver optimization method of the present invention realizes the functions of receiving and sending downlink telemetry data and camera image data from the drone end to the ground end, and uplink remote control data from the ground end to the drone end, while ensuring the stability of the network connection, thereby ensuring the stable remote control operation and flight safety of the drone.
