Description

Communication circuit systems, unmanned aerial vehicles and communication methods Technical Field

[0001] This disclosure relates to the fields of communication technology and unmanned aerial vehicle (UAV) technology, specifically to a communication circuit system, an unmanned aerial vehicle, and a communication method. Background Technology

[0002] With the rapid development of unmanned aerial vehicles (UAVs), various wireless communication functions can be implemented on UAVs. For example, UAVs can use image transmission signals to transmit the image information they have acquired to the control terminal. Another example is that UAVs can continuously broadcast monitoring signals indicating their flight status during operation, allowing regulatory authorities to receive and analyze these signals, thereby analyzing and monitoring the UAV's operational status.

[0003] However, different wireless communication functions typically require signals based on different communication protocols. For example, the communication protocol used for image transmission signals differs from that used for surveillance signals. If a single antenna is used to transmit both image transmission and surveillance signals, signal transmission relies on time-division multiplexing of the antenna, resulting in low image transmission efficiency and impacting the system throughput of the unmanned aerial vehicle. Summary of the Invention

[0004] In view of this, the present disclosure provides a communication circuit system, an unmanned aerial vehicle, and a communication method.

[0032] The embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the disclosure. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the present disclosure for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0033] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0034] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0035] When using expressions such as "at least one of A, B, and C", they should generally be interpreted in accordance with the meaning that is commonly understood by a person skilled in the art (e.g., "a system having at least one of A, B, and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B, and C, etc.).

[0036] With the rapid development and widespread application of unmanned aerial vehicles (UAVs), an increasing number of application scenarios require UAVs to have operational identification capabilities. The implementation of UAV operational identification generally relies on a separate signal link from the image transmission signal link. For example, in one scenario, a WiFi / BT signal link can be used to implement broadcast operational identification.

[0037] Figure 1 shows a schematic diagram of the communication circuit system of an example unmanned aerial vehicle.

[0038] In the example communication circuit system 100 shown in Figure 1, the image transmission signal link 110 may include an image transmission signal chip 111, a first radio frequency front-end device 112, a second radio frequency front-end device 113, and a first combiner 114. The WiFi / BT signal link 120 may include a WiFi / BT signal chip 121 and a second combiner 122. The WiFi / BT signal link 120 and the image transmission signal link 110 can be communicatively connected to the antenna 140 through the radio frequency switch 130, respectively. The image transmission signal chip 111 can transmit a 2.4 GHz image transmission signal via antenna 140 through the first RF front-end device 112, the first combiner 114, and the RF switch 130. Similarly, the image transmission signal chip 111 can transmit a 5 GHz image transmission signal via antenna 140 through the second RF front-end device 112, the first combiner 114, and the RF switch 130. The WiFi / BT signal chip 121 can transmit a 2.4 GHz monitoring signal or a 5 GHz monitoring signal via antenna 140 through the second combiner 122 and the RF switch 130. Both the 2.4 GHz and 5 GHz monitoring signals can be used to achieve the unmanned aerial vehicle's operational identification function.

[0039] Since the WiFi / BT signal link 120 and the image transmission signal link 110 use the same antenna for signal transmission, they need to operate in a time-sharing manner. That is, if the WiFi / BT signal link 120 is active, the image transmission signal link 110 cannot operate, and vice versa. Therefore, if the UAV uses the WiFi / BT signal link 120 to broadcast signals while in flight, the RF switch 130 connects the antenna 140 and the WiFi / BT signal link 120, and the image transmission signal link 110 is inactive. This results in a shorter image transmission time for the UAV, leading to a decrease in the system throughput. Furthermore, the UAV requires additional computing resources to control the time-sharing operation of the image transmission signal link 110 and the WiFi / BT signal link 120, placing higher demands on the performance of the UAV's flight control computer.

[0040] In view of this, embodiments of the present disclosure provide a communication circuit system to at least partially solve the problems described above.

[0041] Figure 2 schematically illustrates a communication circuit system according to an embodiment of the present disclosure.

[0042] As shown in Figure 2, the communication circuit system 200 may include a first communication chip 210, a second communication chip 220, a combiner 230, and an antenna 240.

[0043] The first communication chip 210 can be any type of SDR (Software Defined Radio) chip, and is not limited here. The first communication chip 210 can encode and modulate image data to generate and transmit image transmission signals.

[0044] The second communication chip 220 can be any type of wireless network communication chip, and is not limited thereto. The second communication chip 220 can process the flight status data of the unmanned aerial vehicle to generate monitoring signals, and transmit these monitoring signals via broadcast. The monitoring signals can be signals used for broadcast-style operation identification, and the implementation forms of the monitoring signals include WiFi signals, Bluetooth signals, etc.

[0045] Optionally, the image transmission signal and the monitoring signal can be obtained by encoding based on different communication protocols.

[0046] The combiner 230 can be a duplexer. The combiner can utilize the frequency division function of high-pass, low-pass, or band-pass filters to allow the same antenna to use two signal paths, thereby enabling the same antenna or transmission line to receive and transmit signals of two different frequencies. In the embodiments of this disclosure, the frequency division terminal 231 of the combiner 230 can be connected to the first communication chip 210 and the second communication chip 220, and the combining terminal 232 of the combiner 230 is communicatively connected to the antenna 240.

[0047] Antenna 240 can be any type of radio frequency antenna, which can refer to a device used to transmit and receive radio waves. Antenna 240 can be used to transmit a combined signal, which may include image transmission signals and / or monitoring signals.

[0048] For example, in one operating condition, the first communication chip 210 can transmit an image transmission signal, the combiner 230 can generate a combined signal based on the image transmission signal, and the antenna 240 can transmit the combined signal generated from the image transmission signal. In another operating condition, the second communication chip 220 can transmit a monitoring signal, the combiner 230 can generate a combined signal based on the monitoring signal, and the antenna 240 can transmit the combined signal generated from the monitoring signal. In yet another operating condition, the first communication chip 210 can transmit an image transmission signal, the second communication chip 220 can transmit a monitoring signal, the combiner 230 can generate a combined signal based on the image transmission signal and the monitoring signal, and the antenna 240 can transmit the combined signal generated from the image transmission signal and the monitoring signal.

[0049] According to embodiments of this disclosure, when the frequency band of the image transmission signal is different from that of the monitoring signal, the combiner can combine the image transmission signal from the first communication chip and the monitoring signal from the second communication chip for transmission through its combining function. Therefore, while the UAV is performing operational identification, its image transmission communication function with the ground terminal will not be affected, thereby improving the image transmission performance of the UAV and increasing the system throughput of the UAV.

[0050] The communication chip may have a communication port through which it can communicate with external devices. In some embodiments, the first communication chip may include a first communication terminal, the second communication chip may include a second communication terminal, and the number of combiners in the communication circuit system may be only one. The antenna may include a first antenna.

[0051] Figure 3A schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0052] As shown in Figure 3A, the communication circuit system 300 may include a first communication chip 310, a second communication chip 320, a combiner 330, and a first antenna 340.

[0053] The first communication chip 310 may include a first communication terminal IO1, and the second communication chip 320 may include a second communication terminal IO2. The first communication chip 310 can be used to transmit image transmission signals through the first communication terminal IO1, and the second communication chip 320 can be used to transmit monitoring signals through the second communication terminal IO2.

[0054] A communication chip can transmit a single frequency band signal through a single communication terminal. Alternatively, the first communication chip can also be used to transmit image transmission signals of different frequency bands through a first communication terminal, and the second communication chip can also be used to transmit monitoring signals of different frequency bands through a second communication terminal. For example, the first communication chip 310 may include a first communication terminal IO1 transmitting an image transmission signal in the 2.4 GHz band or an image transmission signal in the 5 GHz band. The second communication chip 320 may include a second communication terminal IO2 transmitting a monitoring signal in the 2.4 GHz band or a monitoring signal in the 5 GHz band. The frequency bands of the signals transmitted by the first communication chip 310 and the second communication chip 320 through the communication terminals can be controlled by a processor and are not limited here.

[0055] The frequency divider of the combiner 330 can be connected to the first communication terminal IO1 and the second communication terminal IO2 respectively to realize the communication connection between the first communication chip 310 and the second communication chip 320. The combiner terminal of the combiner 330 can be connected to the first antenna 340.

[0056] In the embodiments of this disclosure, the frequency band of the image transmission signal and the frequency band of the monitoring signal that the communication circuit system 300 can transmit are different. For example, if the frequency band of the image transmission signal is 5G, then the frequency band of the monitoring signal can be 2.4G. As another example, if the frequency band of the image transmission signal is 2.4G, then the frequency band of the monitoring signal can be 5G. No limitation is made here.

[0057] In the embodiments of this disclosure, the combiner 330 can be used to generate a first combined signal based on the image transmission signal and the monitoring signal, and the first antenna 340 can be used to transmit the first combined signal, thereby achieving synchronous transmission of the image transmission signal and the monitoring signal through frequency division multiplexing.

[0058] The following description uses the example of 2.4G or 5G as the frequency bands for both image transmission and monitoring signals to illustrate the signal transmission operation of the communication circuit system 300.

[0059] Figure 3B schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0060] As shown in Figure 3B, under a signal transmission condition of the communication circuit system 300, the first communication chip 310 can transmit a 5G band image transmission signal through the first communication terminal IO1, and the second communication chip 320 can transmit a 2.4G band monitoring signal through the second communication terminal IO2. The combiner 330 can combine the 5G band image transmission signal and the 2.4G band monitoring signal into a first combined signal, and transmit the first combined signal through the first antenna 340.

[0061] Figure 3C schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0062] As shown in Figure 3C, under another signal transmission condition of the communication circuit system 300, the first communication chip 310 can transmit a 2.4G band image transmission signal through the first communication terminal IO1, and the second communication chip 320 can transmit a 5G band monitoring signal through the second communication terminal IO2. The combiner 330 can combine the 2.4G band image transmission signal and the 5G band monitoring signal into a first combined signal, and transmit the first combined signal through the first antenna 340.

[0063] As another optional implementation, the first communication chip may include multiple first communication terminals, the second communication chip may include multiple second communication terminals, and the number of combiners in the communication circuit system may be multiple. The first communication chip can transmit image transmission signals through multiple first communication terminals, and the second communication chip can transmit monitoring signals through multiple second communication terminals.

[0064] Optionally, in each signal transmission condition of the communication circuit system, the first communication chip can transmit the image transmission signal through only one of the multiple first communication terminals, and correspondingly, the second communication chip can also transmit the monitoring signal through only one of the multiple second communication terminals.

[0065] Each combiner can be used to combine two signals from different frequency bands. Specifically, the frequency divider of each combiner can be connected to a first communication terminal and a second communication terminal, respectively. The frequency band used for transmitting the image transmission signal at the first communication terminal and the frequency band used for transmitting the monitoring signal at the second communication terminal of each combiner are different. The combining terminals of these multiple combiners can all be connected to an antenna for communication.

[0066] Each of the multiple combiners can transmit the combined signal through one antenna. Alternatively, to reduce the hardware cost and size of the communication circuit system, an RF switch can be added to the communication circuit system. Through the gating function of the RF switch, the signal transmission function of multiple combiners can be multiplexed using fewer antennas.

[0067] In embodiments of this disclosure, the antenna may include a first antenna and a second antenna, and the communication circuit system may also include a first radio frequency switch. The first radio frequency switch may include a first contact, a second contact and a plurality of third contacts. The first contact may be connected to the first antenna, the second contact may be connected to the second antenna, and each third contact may be connected to the combining terminal of a combiner.

[0068] The following description uses an example where the first communication chip includes two first communication terminals and the second communication chip includes two second communication terminals to illustrate the embodiments of this disclosure. In this embodiment, the number of combiners can be two, and the first radio frequency switch can be a double-pole double-throw switch.

[0069] Figure 4A schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0070] As shown in Figure 4A, the communication circuit system 400 may include a first communication chip 410, a second communication chip 420, a first combiner 431, a second combiner 432, a first radio frequency switch 440, a first antenna 451, and a second antenna 452.

[0071] The first communication chip 410 may include a first communication terminal IO1_1 and a first communication terminal IO1_2. The first communication chip 410 can transmit image transmission signals of different frequency bands through the first communication terminal IO1_1 and the first communication terminal IO1_2. For example, the first communication chip 410 can transmit a 2.4G frequency band image transmission signal through the first communication terminal IO1_1, or the first communication chip 410 can transmit a 5G frequency band image transmission signal through the first communication terminal IO1_2.

[0072] The second communication chip 420 may include a second communication terminal IO2_1 and a second communication terminal IO2_2. The second communication chip 420 can transmit monitoring signals in different frequency bands through the second communication terminal IO2_1 and the second communication terminal IO2_2. For example, the second communication chip 420 can transmit a 2.4 GHz monitoring signal through the second communication terminal IO2_1, or the second communication chip 420 can transmit a 5 GHz monitoring signal through the second communication terminal IO2_2.

[0073] The frequency divider of the first combiner 431 can be connected to the first communication terminal IO1_1 and the second communication terminal IO2_2, respectively. The first combiner 431 can be used to combine 2.4G band image transmission signals and 5G band monitoring signals. The frequency divider of the second combiner 432 can be connected to the first communication terminal IO1_2 and the second communication terminal IO2_1, respectively. The second combiner 432 can be used to combine 5G band image transmission signals and 2.4G band monitoring signals.

[0074] The first radio frequency switch 440 may include a first contact C1, a second contact C2, a third contact C3_1 and a third contact C3_2. The first contact C1 can be connected to the first antenna 451, the second contact C2 can be connected to the second antenna 452, the third contact C3_1 can be connected to the combining terminal of the first combiner 431, and the third contact C3_2 can be connected to the combining terminal of the second combiner 432.

[0075] In embodiments of this disclosure, the frequency bands of the image transmission signal and the monitoring signal transmitted by the communication circuit system under a signal transmission condition may be different.

[0076] Optionally, the first communication chip can be used to transmit image transmission signals through a first target communication terminal, which can be connected to the frequency divider of a first target combiner; the second communication chip can be used to transmit monitoring signals through a second target communication terminal, which can be connected to the frequency divider of the first target combiner; the first target combiner can be used to generate a first combined signal based on the image transmission signal and the monitoring signal; the first radio frequency switch can be used to transmit the first combined signal through a first antenna via a first contact, or the first radio frequency switch can be used to transmit the first combined signal through a second antenna via a second contact. In embodiments of this disclosure, the first target communication terminal belongs to multiple first communication terminals, the first target combiner belongs to multiple combiners, and the second target communication terminal belongs to multiple second communication terminals.

[0077] Taking the communication circuit system 400 as an example, the first target combiner may be the first combiner 431, and the first radio frequency switch 440 may transmit the first combining signal through the first contact C1 and the first antenna 451.

[0078] Figure 4B schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0079] As shown in Figure 4B, under one signal transmission condition, the first communication chip 410 can transmit a 2.4G band image transmission signal through the first communication terminal IO1_1, and the second communication chip 420 can transmit a 5G band monitoring signal through the second communication terminal IO2_2. The first combiner 431 can combine the 2.4G band image transmission signal and the 5G band monitoring signal to obtain a first combined signal. The first combined signal can be transmitted to the first radio frequency switch 440 via the third contact C3_1. The communication circuit system 400 can control the third contact C3_1 and the first contact C1 in the first radio frequency switch 440 to connect, so that the first combined signal can be transmitted through the first contact C1 and the first antenna 451.

[0080] For example, the first target combiner can be the second combiner 432, and the first radio frequency switch 440 can transmit the first combiner signal through the second contact C2 and the second antenna 452.

[0081] Figure 4C schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0082] As shown in Figure 4C, under another signal transmission condition, the first communication chip 410 can transmit a 5G band image transmission signal through the first communication terminal IO1_2, and the second communication chip 420 can transmit a 2.4G band monitoring signal through the second communication terminal IO2_1. The second combiner 432 can combine the 5G band image transmission signal and the 2.4G band monitoring signal to obtain a first combined signal. The first combined signal can be transmitted to the first RF switch 440 via the third contact C3_2. The communication circuit system 400 can control the connection between the third contact C3_2 and the second contact C2 in the first RF switch 440 so that the first combined signal can be transmitted via the second contact C2 and the second antenna 452.

[0083] In embodiments of this disclosure, under another signal transmission condition, the frequency band of the image transmission signal and the frequency band of the monitoring signal transmitted by the communication circuit system can be the same.

[0084] Optionally, the first communication chip can be used to transmit image transmission signals through a first target communication terminal, which can be connected to the frequency divider of a first target combiner; the second communication chip can be used to transmit monitoring signals through a second target communication terminal, which can be connected to the frequency divider of a second target combiner; the first target combiner can be used to generate a second combined signal based on the image transmission signal; the second target combiner can be used to generate a third combined signal based on the monitoring signal; the first radio frequency switch can be used to transmit the second combined signal through a first antenna via a first contact, and transmit the third combined signal through a second antenna via a second contact. In embodiments of this disclosure, the first target communication terminal belongs to multiple first communication terminals, the first target combiner belongs to multiple combiners, the second target communication terminal belongs to multiple second communication terminals, and the second target combiner belongs to multiple combiners.

[0085] Taking the communication circuit system 400 as an example, the first target combiner may be a first combiner 431, and the second target combiner may be a second combiner 432.

[0086] Figure 4D schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0087] As shown in Figure 4D, under another signal transmission condition, the first communication chip 410 can transmit a 2.4G band image transmission signal through the first communication terminal IO1_1, and the second communication chip 420 can transmit a 2.4G band monitoring signal through the second communication terminal IO2_1. The first combiner 431 can use the 2.4G band image transmission signal as a second combined signal and transmit it to the first RF switch 440 via the third contact C3_1. The second combiner 432 can use the 2.4G band monitoring signal as a third combined signal and transmit it to the first RF switch 440 via the third contact C3_2. The communication circuit system 400 can control the third contact C3_1 and the first contact C1 in the first RF switch 440 to be connected, and the third contact C3_2 and the second contact C2 to be connected, so that the second combined signal can be transmitted via the first contact C1 and the first antenna 451, and the third combined signal can be transmitted via the second contact C2 and the second antenna 452.

[0088] Alternatively, under another signal transmission condition, the first communication chip 410 can also transmit 5G band image transmission signals through the first communication terminal IO1_2, and the second communication chip 420 can also transmit 5G band monitoring signals through the second communication terminal IO2_2. For the sake of simplicity, these will not be elaborated here.

[0089] Optionally, the communication chip in the communication circuit 400 can also transmit signals in different frequency bands through a single communication terminal. For example, the first communication chip 410 can transmit image transmission signals in the 2.4G or 5G frequency band through the first communication terminal IO1_1, and can also transmit image transmission signals in the 2.4G or 5G frequency band through the first communication terminal IO1_2; the second communication chip 420 can transmit monitoring signals in the 2.4G or 5G frequency band through the second communication terminal IO2_1, and can also transmit monitoring signals in the 2.4G or 5G frequency band through the second communication terminal IO2_2.

[0090] Figure 4E schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0091] As shown in Figure 4E, in another signal transmission scenario, the first target combiner can be, for example, the first combiner 431. The first RF switch 440 can transmit the first combined signal via the first antenna 451 through the first contact C1. This differs from the signal transmission scenario shown in Figure 4B. The first communication chip 410 can transmit a 5G band image transmission signal through the first communication terminal IO1_1, and the second communication chip 420 can transmit a 2.4G band monitoring signal through the second communication terminal IO2_2. The first combiner 431 can combine the 5G band image transmission signal and the 2.4G band monitoring signal to obtain the first combined signal. The first combined signal can be transmitted to the first RF switch 440 via the third contact C3_1. The communication circuit system 400 can control the connection between the third contact C3_1 and the first contact C1 in the first RF switch 440 so that the first combined signal can be transmitted via the first contact C1 and the first antenna 451.

[0092] Similarly, under other signal transmission conditions, under the control of the processor, the first communication chip 410 in the communication circuit system 400 can transmit image transmission signals of different frequency bands through the same first communication terminal, and the second communication chip 420 can transmit monitoring signals of different frequency bands through the same second communication terminal. For example, in another signal transmission mode, different from the signal transmission mode shown in Figure 4C, the first communication chip 410 can transmit a 2.4G band image transmission signal through the first communication terminal IO1_2, and the second communication chip 420 can transmit a 5G band monitoring signal through the second communication terminal IO2_1; in another signal transmission mode, different from the signal transmission mode shown in Figure 4D, the first communication chip 410 can transmit a 5G band image transmission signal through the first communication terminal IO1_1, and the second communication chip 420 can transmit a 5G band monitoring signal through the second communication terminal IO2_1; or, in another signal transmission mode, the first communication chip 410 can transmit a 2.4G band image transmission signal through the first communication terminal IO1_2, and the second communication chip 420 can transmit a 2.4G band monitoring signal through the second communication terminal IO2_2. For simplicity, these details will not be elaborated further here.

[0093] As another optional implementation, the first communication chip includes multiple first communication ports, which can be divided into multiple communication port groups, and each communication port group can include a first communication terminal. The first communication chip can synchronously transmit multiple image transmission signals in a single signal transmission mode, that is, it can transmit image transmission signals separately through multiple communication port groups.

The third antenna 542 can be used to transmit one 5G band image transmission signal.

[0108] In the embodiments of this disclosure, by transmitting multiple image transmission signals in a single signal transmission mode using the first communication chip, the signal bandwidth of the image transmission signals can be effectively improved, thereby increasing the throughput of the image transmission communication system. In some embodiments, the frequency bands of the image transmission signals transmitted by the first communication chip 510 through the first communication terminal IO1_1 and the first communication terminal IO1_2 may be different. For example, the first communication chip 510 may transmit a 5G frequency band image transmission signal through the first communication terminal IO1_1 and a 2.4G frequency band image transmission signal through the first communication terminal IO1_2; or, the first communication chip 510 may transmit a 2.4G frequency band image transmission signal through the first communication terminal IO1_1 and a 5G frequency band image transmission signal through the first communication terminal IO1_2, and so on. For the sake of simplicity, these will not be elaborated here.

[0109] Optionally, the first communication chip may include more than two communication port groups. The following description uses an example where the first communication chip includes three communication port groups to illustrate an embodiment of this disclosure. In this example, the number of combiners can be one, and the antenna may include a first antenna and two third antennas.

[0110] Figure 5D schematically illustrates a communication circuit system according to another embodiment of the present disclosure.

[0111] As shown in Figure 5D, the communication circuit system 500B may include a first communication chip 510, a second communication chip 520, a combiner 530, a first antenna 541, a third antenna 542, and a third antenna 543.

[0112] The first communication chip 510 may include a first communication port group 511, a second communication port group 512, and a second communication port group 513. The first communication port group 511 may include a first communication terminal IO1_1, the second communication port group 512 may include a first communication terminal IO1_2, and the second communication port group 513 may include a first communication terminal IO1_3. The second communication chip 520 may include a second communication terminal IO2.

[0113] Optionally, the first communication chip 510 can transmit multiple image transmission signals of different frequency bands through the first communication terminal IO1_1. Similarly, the first communication chip 510 can transmit multiple image transmission signals of different frequency bands through the first communication terminal IO1_2, and the first communication chip 510 can transmit multiple image transmission signals of different frequency bands through the first communication terminal IO1_3. Correspondingly, the second communication chip 520 can transmit multiple monitoring signals of different frequency bands through the second communication terminal IO2.

[0114] Optionally, the frequency band of the image transmission signal transmitted by the first communication chip 510 through the first communication terminal IO1_1 may be different from the frequency band of the monitoring signal transmitted by the second communication chip 520 through the second communication terminal IO2. The combiner 530 can be used to generate a first combined signal based on the image transmission signal and the monitoring signal, and the first antenna 541 can be used to transmit the first combined signal. While the first communication chip 510 transmits the image transmission signal through the first communication terminal IO1_1, the first communication chip 510 can also transmit one image transmission signal each through the first communication terminals IO1_2 and IO1_3 respectively, and the third antennas 542 and 543 can each be used to transmit one image transmission signal. Optionally, the frequency bands of the image transmission signals transmitted by the first communication chip 510 through the first communication terminals IO1_1, IO1_2, and IO1_3 may be the same. For example, the first communication chip 510 can transmit a 5G band image transmission signal through the first communication terminals IO1_1, IO1_2, and IO1_3 respectively. Alternatively, the image transmission signals transmitted by the first communication chip 510 through the first communication terminals IO1_1, IO1_2, and IO1_3 can be in different frequency bands. For example, the first communication chip 510 can transmit a 5G band image transmission signal through the first communication terminal IO1_1, a 2.4G band image transmission signal through the first communication terminal IO1_2, and an 800M band image transmission signal through the first communication terminal IO1_3, and so on. No limitation is made here. The image transmission signals of the 5G band, 2.4G band, and 800M band can be obtained by processing the same image data using different encoding methods. That is, the image transmission signals of the 5G band, 2.4G band, and 800M band can be used to transmit the same image data to ground equipment.

[0115] As another optional implementation, the first communication chip includes multiple first communication ports, and the number of first communication ports used to transmit image transmission signals in the same frequency band can be multiple. Therefore, the multiple first communication ports of the first communication chip can be divided into multiple communication port groups. Each communication port group can include multiple first communication terminals, and the frequency bands of the image transmission signals transmitted by the multiple first communication terminals within a communication port group are all different. For example, the first communication chip can include m×n first communication ports, which can be divided into m communication port groups. Each communication port group can include n first communication ports, and these n first communication ports can be used to transmit image transmission signals from the first frequency band to the nth frequency band. The first communication chip can synchronously transmit multiple image transmission signals in one signal transmission mode, that is, it can transmit image transmission signals separately through multiple communication port groups. The second communication chip can include a second communication terminal, which can be used to transmit monitoring signals through the second communication terminal. The multiple communication port groups can include a first communication port group and at least one second communication port group.

The frequency division terminal of each combiner is connected to a second communication terminal and a first communication terminal of a first communication port group, respectively. The combining terminals of the multiple combiners are communicatively connected to an antenna. The frequency band of the image transmission signal transmitted by the first communication terminal of the first communication port group connected to the frequency division terminal of each combiner and the frequency band of the monitoring signal transmitted by the second communication terminal are different.

[0117] In embodiments of this disclosure, the combining end of each combiner can transmit a combining signal via an antenna, and each first communication end included in each second communication port group can be communicatively connected to an antenna so that each first communication end included in each second communication port group can transmit a transmission signal via an antenna. Optionally, to reduce the hardware cost and size of the communication circuit system, an RF switch can be added to the communication circuit system. Through the gating function of the RF switch, the signal transmission functions of multiple combiners and the signal transmission functions of multiple first communication ends included in each second communication port group can be multiplexed using fewer antennas.

[0118] In embodiments of this disclosure, the antenna may include a first antenna, a second antenna, and at least one third antenna. The number of the third antennas may be the same as the number of the second communication port groups. Each third antenna may be connected to one of the plurality of first communication terminals included in a second communication port group.
