Description

A UAV camera zoom control system for transmission line inspection

technical field

The invention relates to an unmanned aerial vehicle camera zoom control system oriented to transmission line inspection.

Background technique

Transmission lines with high transmission voltage are usually installed in open and remote areas in an elevated manner, which is extremely inconvenient for manual inspection. At present, UAVs are used to inspect transmission lines to improve work efficiency. UAVs are equipped with camera components to take pictures of transmission lines Instead of manual inspection. In the prior art, the camera component on the UAV is a fixed-focus camera. When cruising, the fixed-focus camera cannot zoom to further change the viewing angle. Therefore, when shooting some target details, it needs to be very close to the power transmission line to get a clearer picture. images, however, drones are too close to power transmission lines to meet safety requirements.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide an unmanned aerial vehicle camera zoom control system oriented to transmission line inspection.

The technical solution adopted by the present invention to solve its technical problems is:

An unmanned aerial vehicle camera zoom control system oriented to transmission line inspection, including a control device arranged on the ground, a control module arranged on the unmanned aerial vehicle, a steering gear and a camera component with a zoom ring, the control module controls the connection The steering gear, the output shaft of the steering gear is fixedly socketed with the gear, the gear is meshed with the zoom ring of the camera component, the control device is wirelessly connected to the control module and can control the rotation of the steering gear to drive the gear transmission to adjust the zoom Ring, so as to realize the zoom of the camera part.

In another preferred embodiment, the control device adjusts the focal length of the imaging component according to the distance between the imaging target and the drone, and the greater the distance, the greater the focal length.

In another preferred embodiment, the drone is provided with a distance measuring device for measuring the distance between the camera target and the drone, and the distance measuring device is wirelessly connected with the control device and can measure the distance of the camera target The distance value is fed back to the control device.

In another preferred embodiment, the control module, camera components and steering gear are detachably installed on the platform of the drone.

The beneficial effects of the present invention are:

1. The control module is wirelessly connected to the control device and can control the rotation of the steering gear and adjust the zoom ring through gear transmission, so as to realize the zoom of the camera component, and remotely mechanically control the zoom of the camera component, which can maintain safety during power inspections At the same time, the details of the power facilities are photographed to ensure the safe operation of the drone while taking into account the ability to capture details of the camera components to prevent omissions in inspections.

2. Adjust the focal length of the camera part according to the distance between the camera target and the drone, and ensure the imaging clarity while changing the viewing angle.

3. The control module, camera components and steering gear are detachably installed on the gimbal of the drone, which is convenient for disassembly and replacement, and can be adapted to different camera components.

The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments; however, a UAV camera zoom control system oriented to transmission line inspection of the present invention is not limited to the embodiments.

Detailed ways

Embodiment, referring to Fig. 1 and Fig. 2, a UAV camera zoom control system oriented to transmission line inspection of the present invention includes a control device 100 arranged on the ground end, a control module 200 arranged on the UAV, The steering gear 300 and the camera part 400 with the zoom ring 410, the control module 200 controls and connects the steering gear 300, the output shaft of the steering gear 300 is fixedly socketed with the gear 310, and the gear 310 and the camera part 400 The zoom ring 410 is meshed, the control device 100 is wirelessly connected to the control module 200 and can control the rotation of the steering gear 300 and adjust the zoom ring 410 through the transmission of the gear 310, so as to realize the zoom of the camera part 400, and remotely mechanically control the camera part 400 Zooming can capture details of power facilities while maintaining a safe distance during power inspections, ensuring the safe operation of drones while taking into account the ability of the camera component 400 to capture details and prevent inspection omissions.

The control device 100 adjusts the focal length of the imaging component 400 according to the distance between the imaging target and the UAV. The greater the distance, the greater the focal length, so as to ensure imaging clarity while changing the viewing angle. The distance measurement between the camera target and the UAV can be approximated by the naked eye observation of the operator on the ground, and the operator then controls and adjusts the steering gear 300 through the control device 100 . It is also possible to set a range-finding device for measuring the distance between the camera target and the drone on the drone, and the range-finder is wirelessly connected to the control device 100 and can feed back the distance value of the camera target measured by it to The control device, the operator on the ground controls and adjusts the steering gear 300 through the control device 100 . The distance measuring device may be an infrared distance measuring device, an ultrasonic distance measuring device, a laser distance measuring device or the like. The control module 200, the camera component 400 and the steering gear 300 are detachably installed on the platform 500 of the drone, which is convenient for dismantling and replacement, and can be adapted to different camera components.

The above-mentioned embodiments are only used to further illustrate a kind of unmanned aerial vehicle camera zoom control system oriented to transmission line inspection of the present invention, but the present invention is not limited to the embodiments.
