Description

Technical Field

[0001] This utility model relates to the field of laser remote sensing equipment and satellite orientation, and in particular to an orientation system for laser wind radar. Background Technology

[0002] With the development of the new energy economy and the low-altitude economy, the market demand for laser wind radar is increasing. The prerequisite for obtaining wind field data is to have an accurate reference system. However, the existing laser wind radar technology does not have a directional system and requires manual measurement to determine the direction as a reference system. Furthermore, the existing positioning devices cannot obtain accurate coordinate position information, which affects the reliability of wind field data.

[0003] First, laser wind radar itself does not have a built-in azimuth reference system. The determination of its beam direction usually depends on external references, such as manually set markers, compasses, or GNSS. In practical applications, operators need to manually measure the installation angle of the radar and input it into the system. This process is not only cumbersome, but also prone to human error.

[0004] Secondly, although some lidar systems combine GPS or inertial measurement units for auxiliary positioning, GPS signals are easily blocked in scenarios such as urban canyons, forests, or indoors, leading to positioning drift or failure. Inertial navigation systems will accumulate errors after long-term operation, especially under vibration or motion, the azimuth accuracy will gradually decrease.

[0005] Finally, in mobile measurement scenarios, the radar's orientation will constantly change with the platform's movement. Due to the lack of a real-time, high-precision orientation system, it is difficult to stably calibrate the radar beam's direction, especially under bumpy or turbulent conditions, which may cause the scanning trajectory to deviate from expectations and affect the spatial consistency of wind field data.

[0006] Therefore, a directional system for laser wind radar is provided to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a directional system for laser wind radar that uses satellites to perform directional functions, thereby solving the problem that laser wind radar cannot obtain standard position information when measuring wind, or that there is a large difference in the azimuth of the standard position measured before and after, and improving the accuracy of the wind field reference system and coordinate azimuth.

[0008] To achieve the above objectives, this utility model provides a directional system for a laser wind measuring radar, including a laser wind measuring radar and a receiver box disposed inside the laser wind measuring radar. The receiver box is connected to a main receiver via a first SMA cable, and to a slave receiver via a second SMA cable. The receiver box is connected to a microcomputer via a USB adapter cable. The receiver box is provided with a first SMA interface, a second SMA interface, and a first USB interface.

[0009] Preferably, the main receiver includes a main receiver head and a first magnetic base. The main receiver head is provided with a third SMA interface. One end of the first SMA cable is connected to the first SMA interface, and the other end of the first SMA cable is connected to the third SMA interface.

[0010] Preferably, a first threaded rod is provided between the main receiving head and the first magnetic base, a first threaded groove is provided at the bottom of the main receiving head, a second threaded groove is provided at the top of the first magnetic base, one end of the first threaded rod is connected to the first threaded groove through a threaded structure, and the other end of the first threaded rod is connected to the second threaded groove through a threaded structure.

[0011] Preferably, the receiver includes a receiver head and a second magnetic base. The receiver head is provided with a fourth SMA interface. One end of the second SMA cable is connected to the second SMA interface, and the other end of the second SMA cable is connected to the fourth SMA interface.

[0012] Preferably, a second threaded rod is provided between the receiving head and the second magnetic base, a third threaded groove is provided at the bottom of the receiving head, a fourth threaded groove is provided at the top of the second magnetic base, one end of the second threaded rod is connected to the third threaded groove through a threaded structure, and the other end of the second threaded rod is connected to the fourth threaded groove through a threaded structure.

[0013] Preferably, the microcomputer is provided with a second USB interface, one end of the USB adapter cable is connected to the first USB interface, and the other end of the USB adapter cable is connected to the second USB interface.

[0014] Preferably, the microcomputer has a built-in electronic compass interface. The electronic compass interface displays information including operation buttons, compass image, current compass angle, current direction, latitude and longitude, battery level, environmental information, and angle of deviation from north. The setting buttons include a serial port selection button, a refresh direction button, an auto-rotate button, a stop button, and a sensitivity adjustment button. The environmental information includes temperature, air pressure, and altitude.

[0015] Therefore, the directional system for laser wind radar using the above-described structure of this utility model has the following beneficial effects:

[0016] (1) This solution provides high-precision position and attitude information via satellite, which makes up for the lack of positioning capability of lidar itself, corrects the small displacement or vibration of the radar installation platform, ensures the geographic reference accuracy of wind measurement data, and improves directional stability.

[0017] (2) This solution does not rely on ground references. Satellite signals can directly provide absolute coordinates in remote areas without ground infrastructure, which shortens the equipment installation and startup time and expands the applicable scenarios of radar.

[0018] (3) The orientation system of this solution is directly integrated with the radar control system, realizing fully automatic orientation correction, reducing the need for manual periodic calibration, and lowering the operation and maintenance costs.
