Description

Technical Field

[0001] This utility model discloses a lightweight scattering mobile antenna device, belonging to the field of communication technology; it is suitable for two-end scattering communication stations to carry out scattering communication in a mobile environment. Background Technology

[0002] Due to the Rayleigh fading characteristic of the scattering channel, the signal reception is weak at long communication distances. Traditional scattering antenna devices are limited by narrow antenna beam angles, insufficient real-time antenna alignment, and inability to maintain attitude stability in mobile environments. They can only be used in applications such as "communication in stillness" and "communication when stopped," and cannot support scattering communication in mobile environments. This greatly limits the application areas of scattering communication. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the problem that traditional scattering antenna devices cannot support scattering communication in mobile environments, and to provide a lightweight scattering mobile communication antenna device.

[0004] The present invention achieves the above-mentioned technical effects by adopting the following technical solution:

[0005] A lightweight scattering dynamic mid-channel antenna device includes an antenna base (utility model 1), an antenna turntable (utility model 2), a scattering parabolic antenna (utility model 3), an azimuth driver (utility model 7), an elevation driver (utility model 8), and an antenna control unit (utility model 10); it also includes a Beidou four-arm spiral main antenna (utility model 4), a Beidou four-arm spiral secondary antenna (utility model 5), a Beidou main unit (utility model 6), an inertial navigation system (utility model 9), and an equipment monitoring unit (utility model 11).

[0006] The antenna base utility model 1 is used to support the entire device; the antenna turntable utility model 2 is installed on the antenna base and is used to support the scattering parabolic antenna utility model 3, the Beidou four-arm spiral main antenna utility model 4, the Beidou four-arm spiral secondary antenna utility model 5, the Beidou main unit utility model 6, the azimuth driver utility model 7, the elevation driver utility model 8, the antenna control unit utility model 10, and the equipment monitoring unit utility model 11.

[0007] The utility model 3, a scattering parabolic antenna, is used to transmit and receive scattering signals, providing a hardware foundation for establishing a scattering communication link; the utility model 4, a Beidou four-arm spiral main antenna, and the utility model 5, a secondary antenna, are respectively connected to the Beidou main unit utility model 6, and are used to receive Beidou positioning and orientation signals.

[0008] The Beidou main unit utility model 6 is connected to the equipment monitoring unit utility model 11 for sending and receiving Beidou short messages, and for parsing the positioning and orientation signals received by the Beidou four-wall spiral main antenna utility model 4 and the secondary antenna utility model 5, and reporting the parsed positioning and orientation data to the equipment monitoring unit utility model 11.

[0009] The equipment monitoring unit utility model 11 is connected to the antenna control unit utility model 10. It is used to monitor the parameter status of the lightweight scattering dynamic mid-channel antenna device and to exchange position information with the other end communication station. It sends the positioning and orientation data and the communication azimuth angle calculated by the position information of the two end communication stations to the antenna control unit utility model 10.

[0010] Both the azimuth driver utility model 7 and the elevation driver utility model 8 are connected to the antenna control unit utility model 10, and are used to drive the antenna to rotate in the horizontal and vertical directions, respectively.

[0011] The inertial navigation system utility model 9 is fixed on the antenna base and connected to the antenna control unit utility model 10, and uploads the device attitude data to the antenna control unit utility model 10.

[0012] Furthermore, the equipment monitoring unit 11 is used to monitor the parameter status of the lightweight scattering mobile communication antenna device, and before the scattering communication link is established, it interacts with the other end of the scattering communication station via Beidou short message. After the scattering communication link is established, it interacts with the other end of the communication station via the scattering communication link, calculates the communication azimuth angle in real time based on the position information of the two communication stations, and sends the calculated communication azimuth angle and the positioning and orientation data reported by the Beidou host 6 to the antenna control unit 10.

[0013] Furthermore, the antenna control unit 10 controls the azimuth and elevation angles of the antenna by controlling the azimuth driver 7 and the elevation driver 8. Based on the overall attitude data of the device reported by the inertial navigation system 9 and the positioning and orientation data and communication azimuth angle data issued by the equipment monitoring unit 11, the antenna azimuth and elevation angles are adjusted in real time to keep the attitude of the scattering parabolic antenna stable in the mobile environment, thereby achieving the stability of the scattering communication link.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model utilizes the overall attitude data of the device provided by the inertial navigation system to adjust the azimuth and elevation angles of the scattering parabolic antenna in real time under moving conditions, so that the absolute direction angle and elevation angle of the scattering parabolic antenna remain stable during movement.

[0016] 2. Before the scattering communication link is established, the present invention uses Beidou short message to exchange positions between communication stations. After the scattering communication link is established, the scattering communication link is used to exchange positions. During the movement, the communication azimuth angle is adjusted in real time to ensure the stability and reliability of the scattering communication link in the mobile environment.
