Description

Technical Field

[0001] The present invention relates to the technical field of drone detection, and in particular to a drone zero-value detection device. Background Art

[0002] With the rapid development of drone technology, its applications in military, civilian, and commercial fields are becoming increasingly widespread. The flight stability and safety of drones directly depend on the precise calibration of their sensors and actuators. However, due to factors such as ambient temperature, humidity, and vibration, drone sensors and actuators may experience zero-value drift, leading to flight control failure or even accidents.

[0015] Working principle: When the device is needed, first install the detection module at the center of gravity of the drone, ensure that the installation angle of the sensor group is consistent with the coordinate system of the drone, then start the drone power, the detection module starts to collect data and perform signal conditioning, and then the data processing module analyzes and processes the conditioned signal to determine whether there is zero-value drift, and then the communication module transmits the processing results to the ground control station, and the operator calibrates or adjusts according to the results. The sensor group in the detection module collects the attitude and position information of the drone in real time, and the signal conditioning circuit filters and amplifies the signal output by the sensor and transmits it to the data processing module; the microprocessor in the data processing module analyzes and processes the signal, determines whether there is zero-value drift, and stores the processing results in the memory; the communication module transmits the processing results to the ground control station for the operator to monitor and adjust in real time, thereby achieving high-precision drone zero-value detection, improving the flight stability and safety of the drone, and being able to detect and correct zero-value drift in time during flight, thereby ensuring that the drone maintains a stable attitude and heading during flight.

[0016] When the first motor drives the forward and reverse screws to rotate, it drives the fixed shaft to slide in the grooves of the forward and reverse screws. The forward and reverse screws then slide in the chute through the brush plate driven by the connecting block. The brush plate can then clean the dust on the surface of the detection module and the data processing module. When adjusting the communication module, the detection module and the data processing module are also cleaned, thereby ensuring that they are always clean, improving detection accuracy and data processing efficiency, and also helping to reduce wear and failure rate of the detection module and the data processing module, thereby extending their service life. This not only reduces the maintenance cost of the drone, but also improves the reliability and availability of the drone.

[0017] When the first motor drives the forward and reverse screw rods to rotate, the connecting rod is driven to slide on the second support frame through the forward and reverse screw rods, and then the connecting frame is driven to rotate on the second support frame through the connecting rod, and the connecting frame can drive the connecting frame to swing through the connecting shaft, and the worm is driven by the second motor to rotate the second support frame, and the worm drives the connecting shaft to rotate in the connecting frame through the worm gear, and then the connecting frame can be driven to swing through the worm gear, and the threaded rod can be driven to rotate in the base by twisting the handle, and the clamping arm can be driven to slide on the slide rail through the threaded rod, and the limiting rod can be driven to slide in the base through the clamping arm, so that the communication module can be clamped and fixed. At the same time, it also achieves the effect of flexibly adjusting the position angle of the communication module, thereby improving the efficiency and reliability of data transmission. In complex and changeable flight environments, such as mountainous areas and between high-rise buildings in cities, communication signals may be blocked or interfered with. By flexibly adjusting the position angle of the communication module, the device can help drones better adapt to these environments and ensure the continuity and stability of communication. At the same time, it also achieves the effect of quickly installing or replacing communication modules. When a drone or related equipment fails, quickly installing or replacing the communication module can significantly reduce downtime, which is crucial for tasks that require continuous operation or rapid response.

[0018] The present invention provides a drone zero-value detection device. It has the following beneficial effects: 1.

At the same time, real-time monitoring is also achieved, and zero-value drift can be discovered and corrected in time during flight, thereby ensuring that the drone maintains a stable attitude and heading during flight.

[0019] 2. In the present invention, the first motor drives the forward and reverse screws to rotate, which in turn drives the fixed shaft to slide in the grooves in the forward and reverse screws, and then drives the brush plate to slide in the slide groove, thereby achieving the effect of cleaning the detection module and the data processing module while adjusting the communication module, thereby ensuring that they always remain in a clean state, thereby improving the detection accuracy and data processing efficiency.

[0020] 3. In the present invention, when the first motor drives the forward and reverse screws to rotate, the connecting rod can be driven to slide in the second support frame, and then the connecting frame can be driven to rotate on the second support frame, wherein the second motor drives the worm to rotate in the second support frame, and the worm drives the connecting shaft to rotate in the connecting frame through the worm gear, and then the connecting frame can be driven to swing through the worm gear, which also achieves the effect of flexibly adjusting the position angle of the communication module, thereby ensuring the continuity and stability of communication.
