Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle information transmission, and specifically relates to a multi-band anti-interference unmanned aerial vehicle data transmission link. Background Art

[0002] With the development of drone technology, drones are increasingly being used in various fields. For example, drones can be used for aerial photography, reconnaissance, etc. During the execution of such tasks, drones need to communicate with the ground operator to enable the ground operator to perform the next command operation based on the information sent back by the drone.

[0003] However, due to the distance limitation of signal transmission, the existing UAV data transmission link has low efficiency in data transmission, which affects the working efficiency of the UAV. Utility Model Content

[0004] The main purpose of the utility model is to provide a multi-band anti-interference UAV data transmission link, which is used to improve the data transmission efficiency of the UAV.

[0005] To achieve the above objectives, the utility model provides a multi-band anti-interference UAV data transmission link, which includes a sky end and a receiving end. The sky end includes a connecting line and a signal transmitter. The receiving end includes a shell. Five receiving antennas are arranged on the shell. The five receiving antennas are arranged with different signal receiving frequencies.

[0006] The data transmission of drones generally prefers high frequencies, because high-frequency signals have a larger bandwidth and can transmit data with a larger code stream. However, the transmission distance of high-frequency signals is not far. When the receiving end detects that the signal strength is lower than the set value, it will seamlessly switch to a relatively low frequency. Conversely, it will gradually use higher-frequency signals for large-code stream data transmission. The five receiving antennas with different signal receiving frequencies set in this solution can switch the frequency of the received signal according to the distance of the drone, thereby ensuring that the data signal has a certain strength while improving the efficiency of drone data transmission as much as possible.

[0007] In a possible implementation, the receiving frequencies of the five receiving antennas are, from left to right, 433 MHz, 868 MHz, 1.4 GHz, 2.4 GHz, and 5.8 GHz.

[0008] In a possible implementation, a data communication interface RJ45 is provided on the side of the housing, and the data communication interface RJ45 is used to transmit data information received by the receiving end to the outside.

[0009] In a possible implementation, three of the five receiving antennas are vertically arranged on the top surface of the housing, and the remaining two are symmetrically arranged on both sides of the housing and extended upward after being bent once. This solution reduces the volume of the housing of the receiving end, reduces the occupied space, and facilitates installation.

[0010] In a possible implementation, a universal tripod screw hole is provided at the bottom of the housing, and the receiving end is installed and fixed through the tripod screw hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0015] See attached figure Figure 1 , Figure 1 This is a schematic diagram of a multi-band anti-interference UAV data transmission link structure provided by the utility model, such as Figure 1 As shown, the utility model provides a multi-band anti-interference UAV data transmission link, which includes a sky end 1 and a receiving end 2, wherein the sky end 1 includes a connecting line 3 and a signal transmitter 4, and the receiving end 2 includes a shell 5, and five receiving antennas 6 are arranged on the shell 5, and the five receiving antennas 6 are arranged with different signal receiving frequencies.

[0016] The above-mentioned sky terminal 1 is installed on the drone and is used to transmit data signals to the receiving terminal 2. It can simultaneously send out five data signals corresponding to the receiving frequencies of the receiving antenna 6.

[0017] The data transmission of the UAV generally gives priority to high frequency, because the high frequency signal has a larger bandwidth and can transmit data with a larger code stream, but the transmission distance of the high frequency signal is not far. When the receiving end 2 detects that the signal strength is lower than the set value, it will seamlessly switch to a relatively low frequency. Conversely, it will gradually use higher frequency signals for large code stream data transmission. The five receiving antennas 6 with different signal receiving frequencies set in this scheme can switch the frequency of the received signal according to the distance of the UAV, thereby ensuring that the data signal has a certain strength while improving the efficiency of the UAV data transmission as much as possible.

[0018] In a possible implementation, the receiving frequencies of the five receiving antennas 6 are, from left to right, 433 MHz, 868 MHz, 1.4 GHz, 2.4 GHz, and 5.8 GHz.

[0019] In a possible implementation, a data communication interface RJ45 (reference numeral 7) is disposed on the side of the housing 5. The data communication interface RJ45 is used to transmit the data information received by the receiving end 2 to the outside.

[0020] In a possible implementation, three of the five receiving antennas 6 are vertically arranged on the top surface of the housing 5, and the remaining two are symmetrically arranged on both sides of the housing 5 and extended upward after being bent once. This solution reduces the volume of the housing 5 of the receiving end 2, reduces the occupied space, and facilitates installation.

[0021] In a possible implementation, a universal tripod screw hole 8 is provided at the bottom of the housing 5. The tripod screw hole is used to install and fix the receiving end 2.
