[0018] Figure 1 The following is a flowchart of a drone search and rescue method provided in an embodiment of the present application. The method can be executed by a drone search and rescue device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, which can be a mobile terminal, a PC, or a server. Figure 1As shown, the method includes:

[0019] S110. Determine a signal frequency sweep instruction based on the heartbeat information sent by the search and rescue base station through a control system.

[0020] The control system can be integrated into any mobile device, such as a mobile phone or a computer, or integrated into a remote controller of a drone, wherein the drone has a built-in search and rescue base station.

[0021] The search and rescue base station interacts with the control system via a control link of the UAV.

[0022] In this embodiment, the search and rescue base station and the control system communicate and transmit via the control link of the drone, which can ensure the continuity and stability of communication, thereby improving the search efficiency.

[0023] In this embodiment, after the search and rescue base station is powered on, the search and rescue base station can send heartbeat information to the control system to notify the control system that the search and rescue base station is in a normal working state. The control system determines the signal frequency sweep instruction based on the heartbeat information sent by the search and rescue base station, which can ensure the accurate transmission of the signal frequency sweep instruction, and can adjust the signal frequency sweep instruction according to the heartbeat information, thereby ensuring the smooth progress of the search and rescue process and improving the search and rescue efficiency.

[0024] S120. Determine a frequency sweep result based on the signal frequency sweep instruction by the search and rescue base station.

[0025] In this embodiment, after the search and rescue base station in the drone receives the signal scanning command, the drone flies around the target area, and the search and rescue base station scans the operator signal to obtain the scanning result. Among them, the target area can be understood as the area that needs to be searched and rescued.

[0026] S130. Determine signal configuration parameters based on the frequency scanning result through a control system.

[0027] In this embodiment, the control system can dynamically adjust the signal configuration parameters according to the frequency scanning results to ensure the continuity and reliability of subsequent communication between the search and rescue base station and the target terminal device, thereby improving the search and rescue efficiency.

[0028] The frequency scanning result includes operator signals and non-operator signals.

[0029] Optionally, the control system determines signal configuration parameters based on the frequency scanning result, including: if the frequency scanning result is an operator signal, extracting signal configuration parameters corresponding to the operator signal; if the frequency scanning result is no operator signal, using preset parameters as signal configuration parameters for simulating the operator signal.

[0030] In this embodiment, when the search and rescue base station in the drone performs a frequency scanning operation and finds the presence of an operator signal, the search and rescue base station sends the frequency scanning result to the control system, and the control system extracts the configuration parameters of the operator signal. These parameters may include frequency (EARFCN), cell identifier (PCI), bandwidth, transmission power (pmax), etc. If the frequency scanning result shows that no operator signal is detected, the control system will use preset parameters to simulate the configuration parameters of the operator signal. These preset parameters can be set according to standards or historical data to create a virtual network environment in areas where there is no actual operator signal coverage.

[0031] In this embodiment, the signal configuration parameters are differentiated according to whether there is an operator signal or not. When there is a real operator signal, the parameters of the real operator signal are extracted as the signal configuration parameters. When there is no operator signal, the configuration parameters of the operator signal are simulated to ensure the continuity of the communication connection, and at the same time, more stable services can be provided to users, enhancing user experience and improving the efficiency and safety of search and rescue.

[0032] In this embodiment, there is no restriction on the preset parameters, for example, the parameters may be the following: E-UTRA absolute radio frequency channel number (earfcn) / frequency band (band) / physical cell identifier (pci) / tracking area code (tac) / cell identifier (cellid) / maximum transmit power (pmax) / public land mobile network (plmn) / bandwidth (bandwith).

[0033] S140. Determine identification information of a target terminal device based on the signal configuration parameters through the search and rescue base station.

[0034] The target terminal device can be understood as a mobile device of the trapped person, such as a mobile phone. In this embodiment, the identification information is not limited, and it only needs to be able to uniquely identify the terminal device, such as an International Mobile Equipment Identity code.

[0035] In this embodiment, the search and rescue base station simulates the normal operation of the operator based on the signal configuration parameters, so that the target terminal devices around the search and rescue base station are all connected to the search and rescue base station. After the target terminal devices around the search and rescue base station are successfully connected to the search and rescue base station, the search and rescue base station can obtain the identification information of the target terminal devices.

[0036] Optionally, the search and rescue base station determines the identification information of the target terminal device based on the signal configuration parameters, including: communicating and connecting with terminal devices around the search and rescue base station in accordance with the signal configuration parameters to obtain a connection result; determining that the connection result is the identification information of a terminal device that is successfully connected; and determining the identification information of at least one target terminal device from all successfully connected terminal devices based on the identification information.

[0037] In this embodiment, the search and rescue base station attempts to establish a communication connection with surrounding terminal devices (such as mobile phones, radio beacons, etc.) according to the signal configuration parameters. The search and rescue base station obtains the connection results with the surrounding terminal devices by sending signals and listening for responses. The connection results include successful connection. For successfully connected terminal devices, the search and rescue base station will record the identification information of all successfully connected terminal devices. Since the terminal devices of the rescuers are included in all successfully connected terminal devices, the identification information of the terminal devices of the rescuers needs to be eliminated. Therefore, the terminal device of the trapped person can be determined based on the identification information of the terminal devices of the rescuers from the identification information of all successfully connected terminal devices, the terminal device of the rescuers can be eliminated, and the terminal device of the trapped person can be used as the target terminal device, so that the identification information of at least one target terminal device can be obtained.

[0038] In this embodiment, the method of determining the identification information of at least one target terminal device from all successfully connected terminal devices based on the identification information can improve the accuracy of search and rescue.

[0039] Optionally, after determining the identification information of the target terminal device based on the signal configuration parameters by the search and rescue base station, the method further includes: determining search and rescue statistical information based on the identification information of the target terminal device and pre-stored identity information by a control system.

[0040] The pre-stored identity information can be understood as the identity information of the trapped person. In this embodiment, there is no limitation on the specific identity information, for example, it can be a mobile phone number, name, gender, etc.

[0041] Among them, the search and rescue statistical information may include the number of trapped persons, information of trapped persons, etc.

[0042] In this embodiment, the control system analyzes the identification information of the target terminal device to obtain the corresponding identity information. If it matches the pre-stored identity information successfully, the number of trapped persons and the identity information of the trapped persons can be obtained, and the search and rescue statistical information can be sent to the search and rescue equipment.

[0043] S150. Determine the location information of the target terminal device based on the power information transmitted by the target terminal device at a set frequency domain location through a search and rescue device, so as to perform personnel search and rescue based on the location information.

[0044] In this embodiment, the search and rescue personnel hold the search and rescue equipment and obtain the specific location of the trapped person through the search and rescue equipment, so as to rescue the person. Specifically, the search and rescue equipment determines the location information of the target terminal device based on the power information transmitted by the target terminal device at the set frequency domain position. Among them, the power information can be understood as the signal power intensity. In this embodiment, the location of the target terminal device can be accurately calculated based on the power information transmitted at the set frequency domain position, thereby improving the search and rescue efficiency.

[0045] Optionally, before determining the location information of the target terminal device based on the power information transmitted by the target terminal device at a set frequency domain position through the search and rescue equipment, so as to conduct personnel search and rescue based on the location information, it also includes: sending interaction instructions to the target terminal device through the search and rescue base station, so that the target terminal device interacts with the search and rescue base station at the corresponding set frequency domain position and within the corresponding transmission power range in accordance with the interaction instructions.

[0046] In this embodiment, the search and rescue base station sends an interactive instruction to the target terminal device. The interactive instruction includes operating parameters that the target terminal device needs to follow, such as a specific transmission power range and a set frequency domain position. After receiving the interactive instruction, the target terminal device will adjust its own transmission power and frequency domain position according to the transmission power range and the set frequency domain position in the interactive instruction to improve the accuracy of the search and rescue equipment in determining the target terminal device. The transmission power range can be understood as a range of larger signal power strength to meet the needs of the search and rescue scenario.

[0047] The technical solution of the embodiment of the present application is to determine the signal frequency sweep instruction based on the heartbeat information sent by the search and rescue base station through the control system; determine the frequency sweep result based on the signal frequency sweep instruction through the search and rescue base station; determine the signal configuration parameters based on the frequency sweep result through the control system; determine the identification information of the target terminal device through the search and rescue base station based on the signal configuration parameters; determine the location information of the target terminal device based on the power information transmitted by the target terminal device at a set frequency domain position through the search and rescue device, so as to search and rescue personnel based on the location information.
