In an example, referring to fig. 3, two intercom terminal devices in the first communication device group are communicatively connected using an ad hoc network communication protocol; two intercom terminal devices in the second communication device group are in communication connection by adopting an ad hoc network communication protocol.
It should be appreciated that the Ad-hoc network communication protocol (Ad-hoc Network Protocol) allows devices in the first communication device group and the second communication device group to autonomously discover and establish connections without relying on a preconfigured infrastructure. The device can automatically join or leave the network according to the requirement, so that the self-adaption and flexibility of the network are improved.
In an example, the unmanned aerial vehicle communication module is initialized, and after the unmanned aerial vehicle is started, the wireless communication module built in the unmanned aerial vehicle is started, so that the unmanned aerial vehicle can send and receive wireless signals. Initializing the terminal device group communication module to ensure that each intercom terminal device in the first terminal device group and the second communication device group is powered on and that the wireless communication module thereof is also powered on.
In an example, a Wireless Local Area Network (WLAN) or point-to-point connection is established, and if Wi-Fi is used, the drone may create a WLAN hotspot to which intercom terminal devices in the two device groups connect.
In an example, if a point-to-point communication technology such as Zigbee, loRa, etc. is used, the direct communication connection is established through a preset frequency channel or frequency. And verifying the connection state, wherein the unmanned aerial vehicle and the terminal equipment group mutually send test signals, and verifying whether the communication connection is successfully established.
Step 102: determining a target usage area of the second communication device group; the unmanned aerial vehicle is controlled to put the second communication equipment group into the target use area; and in the target use area, communication connection is established among the intercom terminal devices in the second communication device group by adopting an ad hoc network communication protocol.
In an example, geographical location information is obtained, and the current location information of the drone is obtained using a GPS module or other positioning technology (e.g., beidou, GLONASS, etc.) on the drone. And determining the specific position coordinates required to be put in by the second communication equipment group according to the task demand.
In an example, a flight path is planned, and an optimal flight path is planned according to the current position of the unmanned aerial vehicle and the target use area, so that obstacles and a limited area are avoided. And controlling the unmanned aerial vehicle to put the second communication equipment group into the target use area.
In an example, the second group of communication devices is mounted. And mounting a mounting device on the unmanned aerial vehicle, and fixing the second communication equipment set below or on the side surface of the unmanned aerial vehicle. And starting the unmanned aerial vehicle to fly, and controlling the unmanned aerial vehicle to fly to the target using area according to the planned flight path.
In an example, when the drone approaches the target area of use, accurate positioning is performed by sensors (e.g., cameras, infrared sensors, etc.) on the drone. And controlling the unmanned aerial vehicle to slow down and hover, then releasing the mounting device, and throwing the second communication equipment set to a designated position.
Step 103: and when the minimum distance between the first communication equipment group and the second communication equipment group is larger than the preset distance, controlling the unmanned aerial vehicle to enter a relay communication mode, wherein the unmanned aerial vehicle is a relay node between the first communication equipment group and the second communication equipment group in the relay communication mode.

In the relay communication mode, the unmanned aerial vehicle can monitor the stability and the signal quality of a communication link, and adjust and optimize according to requirements.
It should be appreciated that in the relay mode, the drone establishes a communication connection with at least one intercom terminal device of the first group of communication devices; and the unmanned aerial vehicle and at least one intercom terminal device in the second communication device group establish communication connection.
In this case, the drone may forward the signal from the first communication device group to the second communication device group upon receiving it; the drone may forward the signal from the second communication device group to the first communication device group upon receiving it.
Because the two intercom terminal devices in each communication device group are in communication connection by adopting an ad hoc network communication protocol; therefore, when one intercom terminal device in the second communication device group receives voice data forwarded from the unmanned aerial vehicle, the voice data can be transmitted to each intercom terminal device in the second communication device group through the Ad-hoc protocol.

The minimum distance of the first communication device group and the second communication device group is monitored in real time using a GPS module or a signal strength measurement module. And triggering the unmanned aerial vehicle to enter a relay communication mode when the distance exceeds a preset distance threshold. After receiving the trigger signal, the unmanned aerial vehicle enters a relay communication mode and starts to serve as a relay node between the first communication equipment group and the second communication equipment group. Ensuring that the drone can stably receive and forward communication signals between the two groups of devices.
In an example, the drone monitors the quality of the communication link between the first communication device group and the second communication device group in real-time, using parameters such as signal strength (RSSI), signal-to-noise ratio (SNR), data transmission rate, bit error rate, and the like. It is determined whether the current communication link quality is below a preset value. And if the quality of the communication link is lower than a preset value, starting to adjust the flight position and the flight height of the unmanned aerial vehicle. And according to the signal strength feedback, the unmanned aerial vehicle is moved to the direction with weaker signal, so that the unmanned aerial vehicle is ensured to be in the optimal relay position. The flying height of the unmanned aerial vehicle is adjusted to avoid the obstacle, so that a better signal transmission effect is obtained. And continuously monitoring the quality of the communication link, dynamically optimizing in the adjustment process, and gradually approaching the optimal position and the flying height until the quality of the communication link is larger than or equal to a preset value.
It should be appreciated that in severe environments, such as mountains, forests, and other terrain-complex areas, the unmanned aerial vehicle may avoid obstacles by adjusting the altitude, optimize the signal transmission path, and reduce signal interference and attenuation. This mechanism makes the communication between groups of communication devices more reliable, reducing the risk of communication interruption.
