Description

Technical Field

[0001] The utility model relates to a wireless laser communication device, in particular to a wireless laser communication device for an unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicles. Background Technique

[0002] In recent years, with the rapid development of the unmanned aerial vehicle industry, the application range of unmanned aerial vehicles has become wider and wider. Equipping unmanned aerial vehicles with laser communication devices has become an important research direction due to its unique advantages. Compared with ground communication networks, unmanned aerial vehicle communication networks have the advantages of simple deployment, strong mobility, and high flexibility. By using an aerial unmanned aerial vehicle platform, obstacles can be avoided, and a communication link can be quickly established, which plays an important role in scenarios such as emergency disaster relief. The unmanned aerial vehicle laser communication system includes an APT subsystem, a communication subsystem, and a master control subsystem.

[0003] Chinese Patent No. CN202110945456.5 provides a miniaturized unmanned aerial vehicle laser communication device, including a transmitting optical system, a transmitting mirror, a perforated mirror, a servo swing mirror, a beam splitter, a tracking and capturing lens group, a CMOS camera, a communication receiving lens group, and an APD detector. The laser emitted by the transmitting optical system is reflected by the transmitting mirror and then reaches the servo swing mirror through the perforated mirror, and is reflected by the servo swing mirror and then emitted to a cooperating laser communication device; the laser communication device simultaneously receives the laser signal emitted by the cooperating laser communication device. The received laser is split by the beam splitter after being reflected by the reflecting surfaces of the servo swing mirror and the perforated mirror. The optical path after the beam splitter is divided into two parts. Among them, the transmitted light is received by the APD detector after passing through the communication receiving lens group, and the reflected light is received by the CMOS camera after passing through the tracking and capturing lens group. The present invention simplifies the system complexity by the cooperation of the perforated mirror and the energy beam splitter; the energy loss is low, and no stray light is introduced.

[0004] However, although the above case simplifies the system complexity, has low energy loss, and does not introduce stray light, when the unmanned aerial vehicle is flying, due to more water vapor at high altitudes, the lens on the laser communication device will be covered with a layer of water mist, affecting the communication of the laser communication device carried by the unmanned aerial vehicle.

The connector 209 is a connection terminal that can connect the optical transceiver module 204 and the antenna module 208 together. The model of the lead screw motor 205 is preferably a 16GA030 / 050 lead screw reduction motor. Operating the lead screw motor 205 to start can make the mounting shell 203 slide inside the chute 202, so that when the drone hovers, the horizontal position of the optical transceiver module 204 can be slightly moved to achieve fine adjustment of the optical transceiver module 204, facilitating communication between the laser communication device carried by the drone and the laser communication device on the ground. The dust removal assembly 300 is installed on the outer wall of one side of the housing 201 by bolts. A chute 202 is provided on the outer wall of one side of the housing 201. The mounting shell 203 is slidably connected inside the chute 202. The lead screw motor 205 is installed on the outer wall of one side of the housing 201 by bolts. The output end of the lead screw motor 205 is located inside the chute 202, and the output end of the lead screw motor 205 is fixedly connected to the mounting shell 203. The cover plate 206 is installed on the top of the housing 201 by bolts. The connector 209 is installed on the bottom side of the inner wall of the housing 201 by bolts. The power module 207 and the antenna module 208 are arranged inside the housing 201. The optical transceiver module 204 is electrically connected to the power module 207 and the antenna module 208 respectively through wires. The optical transceiver module 204 is embedded inside the mounting shell 203 by bolts, and the optical transceiver module 204 is electrically connected to the connector 209 through a wire.

[0025] As a technical optimization solution of the present utility model, the dust removal component 300 includes an installation cover 301, an installation cylinder 303, a dustproof net 304, an electric heating sheet 305 and a fan 306. The model of the electric heating sheet 305 is preferably bs-7366, and the model of the fan 306 is preferably a DC4010 cooling fan. The installation cylinder 303 is integrally formed on the outer wall of one side of the installation cover 301. A plurality of air outlets 302 are provided on the outer wall of one side of the installation cover 301. The fan 306 and the electric heating sheet 305 in the dust removal component 300 will start, so that hot air is blown onto the lens of the optical transceiver module 204, thereby drying the water mist and dust on the lens of the optical transceiver module 204, avoiding the influence on laser communication caused by the water mist or dust covering the lens of the optical transceiver module 204, improving the anti-interference ability of the device. The dustproof net 304 is installed at one end of the installation cylinder 303 through bolts, and the electric heating sheet 305 and the fan 306 are installed inside the installation cylinder 303 through bolts.

[0026] As a technical optimization solution of the present utility model, the rotation component 100 includes a connecting frame 101. Two connecting plates 102 are integrally formed on the outer wall of one side of the connecting frame 101. The connecting plates 102 can cooperate with bolts to connect the connecting frame 101 with the drone. A driving motor 103 is installed inside the connecting frame 101 through bolts. The model of the driving motor 103 is preferably 57BYGH650-23. An installation bearing 104 is installed on the outer wall of one side of the connecting frame 101 through bolts. Operating the driving motor 103 to start will cause the housing 201 to rotate around the installation bearing 104, causing the communication component 200 to rotate, so as to facilitate the optical transceiver module 204 to rotate to find a suitable position to communicate with the laser communication device on the ground. The housing 201 is installed on the outer wall of one side of the installation bearing 104 through bolts, and the output end of the driving motor 103 is fixedly connected to the housing 201.

[0027] When the utility model is in use, the device can be connected to the drone through the cooperation of bolts and the connecting plate 102. Then, when the drone flies, the optical transceiver module 204 will be activated, causing the device to emit laser light and connect to the communication device on the ground. During the connection process, the driving motor 103 can be operated to start, causing the housing 201 to rotate around the mounting bearing 104, rotating the communication component 200, so that the optical transceiver module 204 can rotate to find a suitable position to communicate with the laser communication device on the ground. At the same time, during this process, the lead screw motor 205 can be operated to start, causing the mounting shell 203 to slide inside the chute 202, so that when the drone hovers, the horizontal position of the optical transceiver module 204 can be slightly moved to achieve fine adjustment of the optical transceiver module 204, facilitating the communication between the laser communication device carried by the drone and the laser communication device on the ground. Subsequently, when the drone flies to a high altitude, the fan 306 and the electric heating sheet 305 in the dust removal component 300 will be activated, causing hot air to blow onto the lens of the optical transceiver module 204, thereby drying the water mist and dust on the lens of the optical transceiver module 204, avoiding the influence on laser communication caused by a side of water mist or dust covering the lens of the optical transceiver module 204, and improving the anti-interference ability of the device.
