Description

[0002] With the in-depth use of unmanned plane in the power grid field, power equipment inspection through unmanned plane has become a trend. Unmanned plane has the characteristics of high flight height and wide field of view, and when it is applied in power equipment inspection, it can inspect places that cannot be inspected by people and robots, and can timely find equipment defects and hidden dangers of power equipment. When the equipment defects and hidden dangers are found, the staff can timely treat the defects.

[0003] In the process of using unmanned plane to inspect power equipment, the distance between unmanned plane and power equipment is very important.

In the prior art, the unmanned plane is provided with an RTK module, which can accurately control the position of the unmanned plane, so as to ensure the distance between the unmanned plane and the power equipment.

[0004] However, it is found in practice that because the power equipment will cause electromagnetic interference to the RTK module, positioning error is often too large, which leads to the problem that the unmanned plane is close to the power equipment, and the unmanned plane and the power equipment both have safety risks.

When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0024] In the present disclosure, the orientation words such as "inner" and "outer" are defined according to the contour of the corresponding parts themselves unless otherwise stated. The terms such as "first" and "second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance.

[0025] Embodiment 1

[0026] The UAV 1 safety inspection system of the present embodiment can avoid the UAV 1 being too close to the power equipment and prevent the UAV 1 from colliding with the power equipment. The UAV 1 safety inspection system of the present embodiment includes the UAV 1, the distance measuring module 2, and the control module.

[0027] In the present embodiment, the UAV 1 flies along the set inspection path of the power equipment. A plurality of predetermined detection positions are arranged on the set inspection path of the power equipment, and the number of detection positions is determined according to the actual situation, for example, 5 detection positions, 10 detection positions, or 15 detection positions, etc. The power equipment to be detected is installed at each detection position. When the UAV 1 flies along the set inspection path, the UAV 1 can pass through the plurality of detection positions arranged above in sequence. The UAV 1 can realize the detection of the power equipment by shooting the image of the power equipment at the position. Of course, the UAV 1 can also be configured with relevant detection devices to realize the detection of the power equipment.

[0028] The UAV 1 in the present embodiment is a conventional rotor type UAV 1. The UAV 1 is configured with an RTK module, which can be integrated inside the UAV 1. The RTK module is used to obtain the spatial position of the UAV 1. Therefore, the UAV 1 moves towards the predetermined detection position under the guidance of the RTK module.

[0029] The RTK module is susceptible to electromagnetic interference generated by the power equipment, which causes the movement direction of the unmanned aerial vehicle 1 to deviate. Therefore, the embodiment preferably provides the ranging module 2 at the bottom of the unmanned aerial vehicle 1. When the unmanned aerial vehicle 1 moves towards the predetermined detection position according to the guidance of the RTK module, the ranging module 2 works at the same time to detect the distance between the unmanned aerial vehicle 1 and the power equipment. When the distance between the unmanned aerial vehicle 1 and the power equipment is less than a threshold value, the unmanned aerial vehicle 1 can hover to avoid moving towards the power equipment and prevent the unmanned aerial vehicle 1 from colliding with and damaging the power equipment.

[0030] In order to install the ranging module 2, the embodiment provides an installation shell 21 at the bottom of the unmanned aerial vehicle 1. Figure 1 As shown in the figure, the installation shell 21 can be a plastic shell. As shown in the figure, Figure 2 The installation shell 21 is internally structured with a containing cavity. The installation shell 21 is installed on the abdomen of the unmanned aerial vehicle 1 by configuring fasteners. At the same time, when the installation shell 21 is installed on the abdomen of the unmanned aerial vehicle 1, the bottom of the installation shell 21 is located above the bottom of the support 11 of the unmanned aerial vehicle 1, so that when the unmanned aerial vehicle 1 is parked on the ground, the bottom of the installation shell 21 has a gap with the ground to avoid being damaged by friction.

[0031] It can be understood that the installation shell 21 in the embodiment is detachably installed by fasteners. Therefore, after completing the inspection work, the installation shell 21 can be separated from the unmanned aerial vehicle 1. Then the unmanned aerial vehicle 1 can perform other work tasks to improve the utilization rate of the unmanned aerial vehicle 1.

[0032] The ranging module 2 in the embodiment includes a magnetic field detection device and an electric field detection device. The magnetic field detection device can be a magnetic field detection device in the prior art, and the electric field detection device can also be an electric field detection device in the prior art. The ranging module 2 is installed in the installation shell 21, and the installation shell 21 provides an installation basis for the magnetic field detection device and the electric field detection device. In implementation, it can be installed in the installation shell 21 by adhesion or fasteners.

[0033] The magnetic field detection device in the embodiment is used to detect the magnetic field strength. When the unmanned aerial vehicle 1 approaches the power equipment, the distance between the unmanned aerial vehicle 1 and the power equipment is shortened, so that the magnetic field detection device can detect a stronger magnetic field strength, and the electric field detection device can also detect a stronger electric field strength. When the magnetic field detection device detects that the magnetic field strength exceeds a threshold value, and / or the electric field detection device detects that the electric field strength exceeds a threshold value, the unmanned aerial vehicle 1 stops moving to avoid collision with the power equipment. After the unmanned aerial vehicle 1 completes the inspection, the unmanned aerial vehicle 1 moves away from the position.

[0034] It can be understood that the magnetic field detection device and the electric field detection device are preferably configured simultaneously in the embodiment, but in some embodiments, only one of the magnetic field detection device and the electric field detection device can be provided.

[0035] The ranging module 2 and the unmanned aerial vehicle 1 are in signal connection with the control module in the embodiment, and the control module can be an industrial computer module in the prior art. When the ranging module 2 detects that the unmanned aerial vehicle 1 is close to the power equipment, the ranging module 2 transmits a signal to the control module, and the control module controls the unmanned aerial vehicle 1 to hover, so as to avoid the unmanned aerial vehicle 1 from continuing to approach the power equipment.

[0036] Embodiment 2

[0037] The embodiment is improved on the basis of the embodiment 1. When the unmanned aerial vehicle 1 is close to the power equipment due to an unexpected situation and the distance exceeds a threshold value, the unmanned aerial vehicle 1 is prone to collide with the protruding part of the power equipment when moving away from the power equipment. Therefore, it is the most secure for the unmanned aerial vehicle 1 to move away from the power equipment along the safe path.

[0038] The camera is also installed in the housing 21 in the embodiment, and the camera can be configured in multiple and faces different directions. Meanwhile, an indicator lamp is arranged outside the power equipment, and the indicator lamp is arranged in the safe path of the power equipment. The indicator lamp is in signal connection with the control module. The camera configured on the unmanned aerial vehicle 1 can identify the position of the indicator lamp, and then feedback the information to the control terminal.

[0039] Taking a use scenario as an example: when the unmanned aerial vehicle 1 approaches the power equipment, the control module controls the indicator lamp to light. At this time, the position of the indicator lamp is identified through the camera. Then the position signal is fed back to the control module. Finally, the remote operator can manually take over the unmanned aerial vehicle 1, and operate the unmanned aerial vehicle 1 to move along the direction of the indicator lamp, so as to realize that the unmanned aerial vehicle 1 moves away from the power equipment along the safe path, and prevents the unmanned aerial vehicle 1 from colliding with the power equipment.

[0040] The above is only an embodiment of the present application, and the well-known specific structure and characteristics in the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be regarded as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
