Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative labor are within the protection scope of the present application.

[0041] In the related art, for the data transmission and communication of the long-distance unmanned rotorcraft, the 4G or 5G wireless communication module on the unmanned rotorcraft is used to communicate with the relay base station laid within the communication range of the communication module through the way of laying relay base stations on the ground, but this communication method needs to design the route in advance when the unmanned rotorcraft flies for a long distance, so that the unmanned rotorcraft and the relay base station can maintain good visibility and are not blocked by the terrain or the object when the unmanned rotorcraft flies based on the route, so as to avoid the abnormality of the communication link between the unmanned rotorcraft and the relay base station, which makes the route design very complex and difficult to implement. Once there is a shielding situation between the unmanned rotorcraft and the relay base station, the communication between the unmanned rotorcraft and the relay base station will be abnormal or interrupted, which affects the data transmission efficiency of the unmanned rotorcraft and reduces the communication reliability of the unmanned rotorcraft.

[0042] In the embodiment, considering the communication mechanism that the relay base station can communicate with the satellite, a satellite communication module and a long-wave second communication module are arranged on the unmanned rotorcraft, a 4G or 5G communication module is arranged below the unmanned rotorcraft, a long-wave first communication module for communicating with the long-wave second communication module is arranged in the unmanned rotorcraft cabin, the data transmission of the unmanned rotorcraft under the shielding of the rotor is realized, the data transmission of the 4G or 5G communication module to the relay base station is interrupted in the case that the unmanned rotorcraft and the relay base station are shielded, the to-be-transmitted data is transmitted to the long-wave first communication module, the long-wave first communication module is used to transmit the to-be-transmitted data to the long-wave second communication module, the long-wave second communication module transmits the to-be-transmitted data to the satellite communication module, the satellite communication module transmits the to-be-transmitted data to the satellite, communication between the satellite and the relay base station is realized, thereby providing a rotorcraft satellite communication method which is not shielded by the rotor, realizing real-time communication between the unmanned rotorcraft and the relay base station, and ensuring that the relay base station receives the to-be-transmitted data in the process of long-distance flight, and ensuring that the unmanned rotorcraft communication link can stably transmit data and communicate.

[0043] Referring to Figure 1 The embodiment of the utility model provides a kind of communication method based on rotorcraft, which can include the following steps:

[0044] S101, after monitoring the communication module and the communication anomaly of ground relay base station, fly control computer is transmitted to the to-be-transmitted data of communication module, it is transmitted to the long-wave first communication module by cable between long-wave first communication module, wherein, the rotor of the rotorcraft is provided with satellite communication module and long-wave second communication module, and in the rotorcraft cabin below the rotorcraft, the long-wave first communication module for communicating with the long-wave second communication module is arranged;

[0045] In the embodiment, as an optional embodiment, the rotorcraft is an unmanned rotorcraft. The communication module in the rotorcraft cabin includes but is not limited to: 4G communication module, 5G communication module, etc. Among them, the 4G communication module or 5G communication module is the module for communication between the rotorcraft and the ground relay base station in the related technology. However, the 4G communication or 5G communication will be interrupted in the case that the rotorcraft and the relay base station are shielded, thereby affecting the data transmission of the rotorcraft, and the communication reliability of the rotorcraft is not high.

[0046] In the embodiment, the ground relay base station can realize communication with the satellite, and the communication between the ground relay base station and the satellite will not be affected by the terrain and the shielding of the ground object. As an optional embodiment, in the case that the communication between the 4G communication module or 5G communication module and the ground relay base station is affected by shielding, the communication between the rotorcraft and the ground relay base station is realized by using the satellite.

[0047] In this embodiment, in order to reliably receive satellite signals and transmit data to the satellite, the satellite communication module on the rotorcraft for communication with the satellite needs to be arranged on the rotor of the rotorcraft so that there is no obstruction between the satellite and the satellite communication module. Since the 4G communication module or the 5G communication module is arranged in the rotorcraft cabin below the rotor of the rotorcraft, during the flight of the rotorcraft, due to the rapid rotation of the rotor, an obstruction is formed between the satellite communication module and the 4G communication module or the 5G communication module, so that the data on the 4G communication module or the 5G communication module cannot be effectively transmitted to the satellite communication module. Further, above the rotorcraft, except for the rotor space, there is no other effective space, so after the satellite communication module is installed on the rotor, the satellite communication module rotates synchronously with the rotor, and the 4G communication module or the 5G communication module in the rotorcraft cabin is moving relative to the rotor, so that communication between the satellite communication module and the 4G communication module or the 5G communication module cannot be realized through wired communication. Therefore, as an optional embodiment, long-wave communication is considered to be arranged between the satellite communication module and the 4G communication module or the 5G communication module, so that the long-wave communication can effectively pass through the obstruction formed by the rapid rotation of the rotor, that is, the satellite communication module and the long-wave second communication module are arranged on the rotor of the rotorcraft in advance, and the long-wave first communication module for communication with the long-wave second communication module is arranged in the rotorcraft cabin below the rotorcraft.

[0048] In this embodiment, as an optional embodiment, the communication frequency (frequency point) of the long-wave first communication module and the long-wave second communication module includes but is not limited to 315MHz and 433MHz. As an optional embodiment, the communication frequency of the long-wave first communication module in this embodiment is 433MHz, so that the existing 433MHz frequency point related communication equipment can be used, and the development and design of the long-wave first communication module are not required.

[0049] In this embodiment, as an optional embodiment, the communication between the communication module and the ground relay base station is monitored by using a target semiconductor processing board, for example, an STM32 processing board.

[0050] In this embodiment, as an optional embodiment, when the communication between the communication module and the ground relay base station is monitored to be abnormal, the following is included:

[0051] The communication module sends heartbeat information to the ground relay base station according to a pre-set heartbeat period;

[0052] If the heartbeat threshold is exceeded and the heartbeat response information returned by the ground relay base station has not been received, communication abnormality information is sent to the target semiconductor processing board.

[0053] In the embodiment, the communication module exceeds the pre-set heartbeat threshold, and has not received the heartbeat response information from the ground relay base station, so it is determined that the communication between the communication module and the ground relay base station is abnormal, and the target semiconductor processing board is informed. In the subsequent process, if the communication module always determines that the communication between the communication module and the ground relay base station is abnormal, the target semiconductor processing board is no longer informed.

[0054] In the embodiment, the satellite communication is used as a supplement to the communication between the communication module and the ground relay base station, and is used when the communication between the communication module and the ground relay base station is abnormal, and is stopped when the communication between the communication module and the ground relay base station is restored to normal, so as to improve the working life. Therefore, as another optional embodiment, the method further comprises:

[0055] If the time from sending the heartbeat information to the ground relay base station to receiving the heartbeat response information returned by the ground relay base station does not exceed the pre-set heartbeat threshold, the communication recovery information is sent to the target semiconductor processing board.

[0056] In the embodiment, the target semiconductor processing board receives the communication recovery information, starts the communication between the communication module and the ground relay base station, stops the satellite communication, and directly receives the heartbeat response information returned by the ground relay base station within the pre-set heartbeat threshold, and no longer sends the communication recovery information to the target semiconductor processing board.

[0057] In the embodiment, as an optional embodiment, the data to be transmitted by the flight control computer to the communication module is transmitted to the long-wave first communication module through the cable between the long-wave first communication module and the target semiconductor processing board, and the method comprises:

[0058] The target semiconductor processing board receives the communication abnormality information, receives the data to be transmitted output by the flight control computer, and transmits the data to be transmitted to the long-wave first communication module through the cable between the target semiconductor processing board and the long-wave first communication module.

[0059] In this embodiment, the flight control computer is a computer provided on the rotorcraft for receiving data collected by each sensor arranged on the rotorcraft, and sending instructions transmitted by the communication module to each sensor. The flight control computer processes the data collected by each sensor, and transmits the data to the target semiconductor processing board through a cable between the flight control computer and the target semiconductor processing board. The target semiconductor processing board receives the data to be transmitted transmitted by the flight control computer, and transmits the received data to be transmitted to the currently determined data transmission link through the cable according to the currently determined data transmission link. For example, after the target semiconductor processing board receives the communication abnormality information, the currently determined data transmission link is the satellite communication link, and the data to be transmitted is transmitted to the long-wave first communication module through the cable; for another example, the communication module confirms that the communication between the communication module and the ground relay station is restored to normal by sending heartbeat information to the ground relay station, and after the communication module sends the communication recovery information to the target semiconductor processing board, the target semiconductor processing board determines that the currently determined data transmission link is the 4G communication link between the communication module and the ground, and then transmits the data to be transmitted to the communication module through the cable, so that the communication module modulates the data to be transmitted to the frequency point of the communication module and sends it.

[0060] In this embodiment, as an optional embodiment, the flight control computer and the target semiconductor processing board are in wired communication (serial communication), and the target semiconductor processing board and the communication module, and the target semiconductor processing board and the long-wave first communication module are in wired communication.

[0062] In this embodiment, the long-wave first communication module receives the data to be transmitted transmitted from the target semiconductor processing board through the cable, and modulates the data to be transmitted according to the communication frequency (frequency point) of the long-wave first communication module. The modulated data to be transmitted is transmitted to the long-wave second communication module through the long-wave antenna.

[0063] In this embodiment, the frequency point of the long-wave first communication module is 433MHz, and the wireless signal of 433MHz is strong, has long transmission distance, strong penetration and diffraction ability, small transmission process attenuation, and can effectively penetrate the shielding formed by the fast rotating rotor.

[0064] S103, control the long-wave second communication module to demodulate and obtain the data to be transmitted, and transmit it to the satellite communication module;

[0065] In the embodiment, the long-wave second communication module receives the modulated to-be-transmitted data by using the long-wave antenna, demodulates the received modulated to-be-transmitted data, obtains the to-be-transmitted data, and transmits the to-be-transmitted data to the satellite communication module through a cable between the long-wave second communication module and the satellite communication module.

[0066] In S104, the satellite communication module modulates the received to-be-transmitted data to a communication frequency of a satellite, transmits the to-be-transmitted data to the satellite, and enables the satellite to transmit the received to-be-transmitted data to the ground relay base station.

[0067] In the embodiment, the satellite communication module modulates the received to-be-transmitted data according to a frequency point of the satellite, transmits the modulated to-be-transmitted data to the satellite through a satellite antenna, and transmits the to-be-transmitted data to the ground relay base station through the satellite, thereby effectively transmitting the data of the rotorcraft to the ground relay base station in the case that the communication module and the ground relay base station are blocked, and ensuring the reliability of data transmission.

[0068] The communication method based on a rotorcraft in the embodiment of the utility model, through the communication module and the ground relay base station after monitoring the communication abnormality, the flight control computer is transmitted to the to-be-transmitted data of the communication module, through the cable between the long-wave first communication module and the long-wave second communication module, is transmitted to the long-wave first communication module, wherein, the rotorcraft is provided with the satellite communication module and the long-wave second communication module on the rotor, and the long-wave first communication module that communicates with the long-wave second communication module is arranged in the rotorcraft cabin below the rotorcraft, the long-wave first communication module modulates the received to-be-transmitted data to the communication frequency of the long-wave first communication module, and is transmitted to the long-wave second communication module, the long-wave second communication module demodulates and obtains the to-be-transmitted data, and is transmitted to the satellite communication module, the satellite communication module modulates the received to-be-transmitted data to the communication frequency of the satellite, and is transmitted to the satellite, to enable the satellite to transmit the received to-be-transmitted data to the ground relay base station. In this way, by arranging the long-wave second communication module on the rotorcraft and arranging the long-wave first communication module that communicates with the long-wave second communication module below the unmanned rotorcraft, data transmission of the unmanned rotorcraft under the shielding of the rotor is realized, thereby in the case that the rotorcraft and the ground relay base station are blocked, the to-be-transmitted data is transmitted to the ground relay base station through the long-wave first communication module, the long-wave second communication module, the satellite communication module and the satellite, an effective supplement to the communication between the communication module and the ground relay base station is formed, the data transmission efficiency can be effectively improved, and the reliability of data transmission is ensured.
