Description

Technical Field

[0001] This application relates to the field of signal transmission technology, and in particular to a signal transmission system, method, drone, drone control equipment, and computer program product for unmanned aerial vehicles (UAVs). Background Technology

[0002] Transmission lines are exposed to the air for extended periods, making them susceptible not only to the pressure of power loads but also to damage from external forces such as lightning flashovers, pollution corrosion, and wind and rain. This results in potential hazards such as worn and missing insulators, broken conductor strands, and missing vibration dampers. To promptly eliminate these hazards and ensure the safety of power supply, regular inspections of the transmission lines and their surroundings are necessary. However, the surrounding environment of transmission lines may contain complex terrain and vegetation, necessitating the use of drones for intelligent inspections.

[0003] In traditional technologies, signal transmission between the drone and its control equipment typically involves deploying a signal receiver and receiving antenna on the drone itself, and a signal transmitter and transmitting antenna on the drone's control device. The control device sends control signals to the drone via the transmitting antenna, instructing it to transmit image signals in return. The drone receives the control signals via its receiving antenna and transmits image signals back, thus achieving signal transmission between the drone and its control device. However, using traditional drone signal transmission systems presents challenges due to the significant distance between the receiving and transmitting antennas, leading to antenna mismatch. Furthermore, the transmitted signals are easily blocked by obstacles, resulting in a short signal transmission distance. Summary of the Invention

[0004] Therefore, it is necessary to provide a signal transmission system, method, drone, drone control equipment, and computer program product for drones with long signal transmission distances to address the above-mentioned technical problems.

[0022] According to the third routing information, the data signal and the first routing information are transmitted to the third network chip of the next relay drone. The third network chip of the next relay drone is instructed to repeatedly perform the operation of obtaining the third routing information corresponding to the next relay drone when the topological distance between the relay drone and the communication base station is greater than the preset threshold, and transmitting the data signal and the first routing information to the third network chip of the next relay drone according to the third routing information, until the topological distance between the relay drone and the communication base station is less than the preset threshold, and then transmitting the data signal and the first routing information to the communication base station.

[0023] In one embodiment, the number of relay drones is multiple;

[0024] The first network chip is also used for:

[0025] If the topological distance between the target UAV and the communication base station is greater than a preset threshold, the target routing information and the target relay UAV corresponding to the target routing information are determined from the second routing information corresponding to the multiple relay UAVs based on the base station routing information of the communication base station.

[0026] According to the target routing information, the data signal and the first routing information are transmitted to the third network chip of the target relay UAV.

[0027] In one embodiment, the relay drone is equipped with a mobile base station;

[0044] Figure 1 An exemplary signal transmission system 100 for a drone is shown, comprising: a target drone 102, a communication base station 104, and a drone control device 106.

[0045] Among them, the target drone 102 can be used to characterize the working drone that performs inspection operations.

[0046] The target drone 102 may be equipped with a first network chip. The first network chip can be used to characterize a chip with signal transmission and reception capabilities, such as a wireless network card, a SIM card (Subscriber Identity Module), etc.

[0047] The data signal can be, but is not limited to, any one or more of a variety of signals, including image signals, sound signals, or temperature signals. In one example, if an image acquisition device is deployed in the target drone 102, the data signal detected by the target drone 102 can be an image signal. In another example, if an acoustic acquisition device is deployed in the target drone 102, the data signal detected by the target drone 102 can be a sound signal.

[0048] Communication base station 104 can be used to characterize an interface device for mobile devices to access the Internet, such as a public mobile communication base station.

[0049] The drone control device 106 can be used to control a drone. A second network chip may be deployed in the drone control device 106. In one example, the drone control device 106 can be, but is not limited to, any of the following devices: personal computer, laptop, smartphone, tablet, IoT device, and portable wearable device. The IoT device can be a smart TV, smart in-vehicle device, etc. The portable wearable device can be a smartwatch, smart bracelet, head-mounted device, etc.

[0050] The first routing information can be used to characterize the network address of the drone control device 106.

[0051] Specifically, during the operation of the target drone 102, the first network chip in the target drone 102 can be set to an active state. The data signals detected by the target drone 102 and the first routing information of the drone control device 106 corresponding to the target drone 102 are transmitted to the communication base station 104 via the first network chip. The first routing information can be information stored in the target drone 102 during its factory configuration phase, or it can be information received through the first network chip.

[0052] In one example, the target drone 102 can transmit the detected data signal to the communication base station 104 in real time, or it can periodically transmit the detected data signal within a preset period to the communication base station 104. In another example, the target drone 102 can also transmit the detected data signal to the communication base station 104 in response to receiving the data acquisition signal forwarded by the communication base station 104.

[0053] The communication base station 104 can wirelessly receive data signals transmitted by the target drone 102 and the first routing information of the drone control device 106. According to the first routing information of the drone control device 106, it transmits the data signals detected by the target drone 102 to the drone control device 106 wirelessly. In one example, the communication base station 104 can perform filtering and / or signal amplification processing on the received data signals to enhance their signal strength. In another example, the wireless communication method can be, but is not limited to, any of the following: wireless network communication, radio frequency signal communication, Bluetooth communication, etc.

[0054] The drone control device 106 can wirelessly communicate with the communication base station via the second network chip and receive data signals sent by the communication base station 104. Subsequently, the drone control device 106 can process the data signals to determine the status of the area inspected by the target drone 102.

[0055] The aforementioned UAV signal transmission system utilizes a target UAV, a communication base station, and UAV control equipment to construct the system. The target UAV is equipped with a first network chip, which transmits data signals detected by the target UAV and first routing information from the corresponding UAV control equipment to the communication base station. The communication base station receives the data signals and the first routing information and transmits the data signals to the UAV control equipment according to the first routing information. The UAV control equipment is equipped with a second network chip, which receives data signals and communicates with the communication base station. The communication base station acts as a signal relay station between the target UAV and the UAV control equipment. This not only avoids the problem of obstacles affecting direct signal transmission between the target UAV and the UAV control equipment but also utilizes the signal forwarding capability of the communication base station to further extend the signal transmission distance. Furthermore, when forwarding signals through the communication base station, the base station can enhance the signal, thereby improving the signal strength during transmission.

[0056] In one embodiment, the first network chip is further configured to: determine base station routing information of the communication base station based on the first routing information; determine the topological distance between the communication base station and the target drone based on the base station routing information and the drone routing information corresponding to the target drone; and transmit the data signal and the first routing information to the communication base station if the topological distance between the target drone and the communication base station is less than a preset threshold.

[0057] Specifically, the target drone can perform the following operations via the first network chip: Based on first routing information, determine the communication base station corresponding to the drone control device, and determine the base station routing information of the communication base station. Perform calculations on the base station routing information corresponding to the communication base station and the drone routing information corresponding to the target drone to determine the topological distance between the communication base station and the target drone in the wireless network. Compare the topological distance with a preset threshold. If the topological distance between the target drone and the communication base station is less than the preset threshold, transmit the data signal and the first routing information to the communication base station, instructing the communication base station to send the data signal to the drone control device according to the first routing information. The preset threshold can be determined based on the communication transmission distance of the first network chip.

[0058] In one example, if the topological distance between the target drone and the communication base station is determined to be less than a preset threshold, the communication base station is determined to be within the signal transmission range of the target drone, and the target drone can directly transmit signals with the communication base station. In another example, if the topological distance between the target drone and the communication base station is determined to be greater than a preset threshold, the target drone and the communication base station cannot communicate directly, and a third-party device is needed as a relay station for signal transmission between the target drone and the communication base station.

[0059] In this embodiment, by determining the topological distance between the communication base station and the target UAV, and when the topological distance between the target UAV and the communication base station is less than a preset threshold, the data signal and the first routing information are transmitted to the communication base station, which can improve the transmission efficiency of the data signal.

[0060] In one embodiment, the drone's signal transmission system also includes a relay drone.

[0061] The relay drone may be equipped with a third network chip, which is used to access the multi-hop wireless network and communicate with the communication devices under the multi-hop wireless network.

[0062] Multi-hop wireless networks can be, but are not limited to, any of the following types of networks: Ad Hoc networks (a type of mobile network without wired infrastructure support, where all nodes are mobile hosts), MWN networks (Multi-Hop Wireless Networks, a type of multi-hop wireless network), and Mesh Networks (a type of multi-hop wireless network).

[0063] Specifically, the target drone can establish a multi-hop wireless network through the first network chip. The drone routing information of the target drone and the base station routing information of the communication base station are processed to determine the topological distance between the target drone and the communication base station in the multi-hop wireless network. If the topological distance between the target drone and the communication base station in the multi-hop wireless network is greater than a preset threshold, it is determined that the target drone and the communication base station cannot communicate directly. The second routing information corresponding to the relay drone under the multi-hop wireless network is obtained. According to the second routing information, data signals and the first routing information are sent to the third network chip in the relay drone through the multi-hop wireless network, instructing the third network chip to send the data signal to the communication base station.

[0064] The relay drone can connect to a multi-hop wireless network through a third network chip, receive data signals and first routing information sent by the target drone through the multi-hop wireless network, and establish a connection with the communication base station through the third network chip to transmit the data signals and first routing signals to the communication base station.

[0065] In this embodiment, when the topological distance between the target drone and the communication base station in the multi-hop wireless network is determined to be greater than a preset threshold, the data signal of the target drone and the first routing information of the drone control device are sent to a relay drone. The relay drone then forwards the signal to the communication base station, thereby improving the communication distance of the signal transmission system. Furthermore, since the drone signal transmission system provided in this embodiment uses a relay drone for signal transmission, it leverages the high signal transmission efficiency of the relay drone, allowing the user to promptly obtain the data signal detected by the target drone while it is operating. This avoids the problem of the drone colliding with or hitting power lines due to a lack of signal during power line inspections.

[0066] In one embodiment, for each relay drone, the corresponding third network chip is further configured to: when the topological distance between the relay drone and the communication base station is greater than a preset threshold, obtain the third routing information corresponding to the next relay drone; transmit the data signal and the first routing information to the third network chip of the next relay drone according to the third routing information; instruct the third network chip of the next relay drone to repeatedly perform the operation of obtaining the third routing information corresponding to the next relay drone and transmitting the data signal and the first routing information to the third network chip of the next relay drone according to the third routing information when the topological distance between the relay drone and the communication base station is greater than the preset threshold, until the topological distance between the relay drone and the communication base station is less than the preset threshold, and transmit the data signal and the first routing information to the communication base station.

[0067] Specifically, after the current relay drone receives the data signal and first routing information sent by the target drone, it determines the topological distance between the current relay drone and the communication base station in the multi-hop wireless network. If the topological distance between the current relay drone and the communication base station is greater than a preset threshold, it obtains the third routing information corresponding to the next relay drone in the multi-hop wireless network. According to the third routing information, the data signal and the first routing information are transmitted to the third network chip of the next relay drone. The third network chip of the next relay drone repeats the operation performed by the third network chip of the current relay drone until the topological distance between the current relay drone and the communication base station in the multi-hop wireless network is less than the preset threshold, at which point the current relay drone is instructed to transmit the data signal and the first routing information to the communication base station.

[0068] In this embodiment, several relay drones in a multi-hop wireless network forward the data signal and first routing information of the target drone until the data signal and first routing information are transmitted to the communication base station, which can improve the signal transmission distance.

[0069] In one embodiment, a multi-hop wireless network may employ an Ad Hoc network.

[0070] Specifically, the target drone can establish an Ad Hoc network through the first network chip and communicate with relay drones within the Ad Hoc network. When the topological distance between the target drone and the relay drone is less than a preset threshold (i.e., both drones are within each other's communication coverage area), the target drone can communicate directly with the relay drone through the Ad Hoc network. When the topological distance between the relay drone and the communication base station exceeds the preset threshold, the target drone needs to acquire another relay drone from the Ad Hoc network and use that drone to forward signals until the topological distance between the relay drone and the communication base station is less than or equal to the preset threshold. At this point, the data signal and first routing information are directly sent to the communication base station.

[0071] In this embodiment, by employing an Ad Hoc network as a multi-hop wireless network, signal transmission between the target UAV and the relay UAV is achieved. Leveraging the characteristics of Ad Hoc networks, each relay UAV within the network acts as a route, enabling the acquisition of routing information and the transmission and reception of signals, thereby improving signal transmission efficiency. Furthermore, because Ad Hoc networks use packet switching mechanisms from computer networks rather than circuit switching, they can quickly establish a mobile communication network anytime, anywhere, without requiring hardware infrastructure support, and are independent of existing network communication facilities, thus possessing a degree of independence.

[0072] In one embodiment, there are multiple relay drones. The first network chip is further configured to: when the topological distance between the target drone and the communication base station is greater than a preset threshold, determine the target routing information and the target relay drone corresponding to the target routing information from the second routing information corresponding to the multiple relay drones based on the first routing information, and transmit the data signal and the first routing information to the third network chip of the target relay drone according to the target routing information.

[0073] Specifically, multiple relay drone nodes can exist in the multi-hop wireless network established by the first network chip of the target drone. When the topological distance between the target drone and the communication base station exceeds a preset threshold, the target drone cannot directly transmit signals to the communication base station and needs to forward signals through relay communication equipment. Based on the base station routing information of the communication base station and the drone routing information of the target drone, the target routing information, which has a topological distance to both the communication base station and the target drone less than the preset threshold, and the target relay drone corresponding to the target routing information, is determined from the second routing information corresponding to the multiple relay drones in the multi-hop wireless network. According to the target routing information, data signals and the first routing information are sent to the target relay drone through the multi-hop wireless network, instructing the third network chip of the target relay drone to send the data signals and the first routing information to the communication base station.

[0074] In this embodiment, by determining the target relay drone based on the base station routing information of the communication base station when there are multiple relay drones and the topological distance between the target drone and the communication base station is greater than a preset threshold, the efficiency of determining the target relay drone can be improved, thereby improving the efficiency of signal transmission.

[0075] In one embodiment, a mobile base station is deployed on the relay drone. When operating normally, the mobile base station transmits data signals and first routing information to the drone control device via Ethernet. A third network chip transmits the data signals and first routing information to the communication base station via a multi-hop wireless network when the mobile base station malfunctions.

[0076] Specifically, a mobile base station can be deployed within the relay drone. When the mobile base station is functioning normally, the target drone can transmit data signals and initial routing information to the relay drone's mobile base station via Ethernet. Upon receiving the data signals and initial routing information, the mobile base station can reshape and amplify the data signals. Following the initial routing information, it then transmits the processed data signals to the drone's control equipment via Ethernet.

[0077] In the event of a mobile base station failure, the relay drone cannot communicate with the target drone and its control equipment via Ethernet. The target drone can send data signals and first routing information to the relay drone's third network chip via the first network chip, instructing the third network chip to transmit the data signals and first routing information to the communication base station via a multi-hop wireless network, so that the communication base station can forward the data signals to the drone control equipment.

[0078] In one example, when the mobile base station is operating normally, the third network chip of the relay drone can be in a powered-off state or a low-power state. In this case, the relay drone can avoid connecting to the multi-hop wireless network established by the target drone's first network chip.

[0079] In another example, the target drone can be configured to transmit signals in a specific order. For instance, it can first send data signals and initial routing information to the relay drone via Ethernet. If the Ethernet communication is not completed within a preset time period, the data signals and initial routing information are then sent to the relay drone's third network chip using the first network chip.

[0080] Compared to traditional UAV signal transmission systems that rely solely on relay UAVs carrying mobile base stations to establish communication between the target UAV and the mobile base station, as well as between the UAV control equipment and the mobile base station via Ethernet, the UAV signal transmission system provided in this embodiment reduces signal transmission costs and enhances UAV signal regeneration by utilizing the mobile base station for signal forwarding when the mobile base station is functioning normally. Furthermore, it mitigates the impact of mobile base station failures on signal transmission and increases the signal transmission distance by utilizing a third network chip for signal forwarding when the mobile base station is malfunctioning.

[0081] In one embodiment, such as Figure 2 As shown, a signal transmission system 200 for unmanned aerial vehicles (UAVs) is provided, including: a target UAV 202, a relay UAV 204, a communication base station 206, and a UAV control device 208.

[0082] The target drone 202 is equipped with the first network chip.

[0083] The relay drone 204 is equipped with a third network chip and a mobile base station.

[0084] A second network chip is deployed in the drone control device 208.

[0085] Specifically, the target drone 202 can transmit the detected data signal and the first routing information of the drone control device 208 to the mobile base station of the relay drone 204 via Ethernet. When the mobile base station is functioning normally, the mobile base station of the relay drone 204 can transmit the data signal to the drone control device 208 corresponding to the first routing information via Ethernet.

[0086] In the event of a mobile base station failure, if the target UAV 202 determines that signal transmission has failed within a preset time after transmitting a signal via Ethernet, it can establish a multi-hop wireless network through the first network chip. The first network chip can then transmit the data signal and first routing information to the third network chip in the relay UAV 204 via the multi-hop wireless network, instructing the third network chip to transmit the data signal and first routing information to the communication base station 206, so that the communication base station 206 can forward the data signal to the UAV control device 208.

[0087] In one example, when the topological distance between the relay drone 204 and the communication base station 206 is greater than a preset threshold, the third network chip is also used to obtain the second routing information of the next relay drone 204, send the data signal and the first routing information to the third network chip of the next relay drone 204, and instruct the third network chip of the next relay drone 204 to repeat the above operation until the distance between the relay drone 204 and the communication base station 206 is less than the preset threshold, and then send the data signal and the first routing information to the communication base station 206 through the third network chip.

[0088] In this embodiment, a signal transmission system for the drone is constructed using a target drone, a relay drone, a communication base station, and drone control equipment. A first network chip is deployed in the target drone, a third network chip and a mobile base station are deployed in the relay drone, and a second network chip is deployed in the drone control equipment. When the mobile base station is functioning normally, Ethernet is used to enable communication between the target drone and the relay drone, and between the relay drone and the drone control equipment. This not only reduces signal transmission costs but also allows the relay drone to amplify the data signal, increasing the strength of the transmitted signal. When the mobile base station is faulty, a multi-hop wireless network is established using the first network chip. This multi-hop wireless network enables communication between the target drone and the relay drone, allowing each relay drone to act as a route, possessing the ability to acquire routing information and send / receive signals, thereby improving signal transmission efficiency and distance.

[0089] Based on the same inventive concept, this application also provides a signal transmission method for a drone to implement the signal transmission system of the drone mentioned above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more drone signal transmission method embodiments provided below can be found in the limitations of the drone signal transmission system described above, and will not be repeated here.

[0090] In one embodiment, such as Figure 3As shown, a signal transmission method for a drone is provided, applied to a drone signal transmission system. The drone signal transmission system includes a target drone, a communication base station, and a drone control device. The target drone has a first network chip deployed in it, and the drone control device has a second network chip deployed in it. The method includes the following steps:

[0091] Step S302: The data signal detected by the target UAV and the first routing information of the UAV control device are transmitted to the communication base station through the first network chip.

[0092] In step S304, the data signal is sent to the UAV control device via the communication base station according to the first routing information.

[0093] Step S306: Receive data signals through the second network chip of the drone control device.

[0094] Specifically, the UAV's signal transmission system can transmit the data signal detected by the target UAV and the first routing information of the corresponding UAV control device to the communication base station via the target UAV's first network chip. The communication base station amplifies and shapes the data signal, and then sends the processed data signal to the UAV control device according to the first routing information. The second network chip of the UAV control device receives the data signal sent by the communication base station.

[0095] The above-mentioned signal transmission method for drones enables communication between the target drone and the communication base station through a first network chip, amplifies and shapes the data signal through the communication base station, and enables communication between the communication base station and the drone control equipment through a second network chip. This method can improve the signal strength during signal transmission and increase the signal transmission distance.
