TECHNICAL FIELD

[0001] The utility model belongs to the positioning system field, concretely relates to photovoltaic cleaning system. BACKGROUND

[0002] The visual guidance module is a positioning navigation system based on image recognition technology, which is widely used in production and life. For example: the unmanned aerial vehicle can realize accurate positioning through the visual positioning system. The visual positioning system usually includes a positioning mark and a camera module for identifying the positioning mark. The positioning mark is set at the positioning position, the camera module identifies the positioning mark, and finally the position of the positioning system is identified through calculation.

[0003] In the prior art, the guide mark of the visual positioning system is usually a T-shaped or H-shaped color mark, which is recognized by the camera module according to the corresponding color and symbol. For example: black T-shaped mark.

[0004] However, since the camera module in the prior art identifies by color and symbol, in order to facilitate the identification of the camera module (especially to facilitate the identification of the unmanned aerial vehicle in the air), the guide mark needs to be set to a larger size. Obviously, when the size of the guide mark is large, the conventional guide mark cannot be set in some special application scenarios (for example: the guide mark needs to be set on some devices and equipment with small size). INVENTION CONTENTS

[0006] In order to achieve the above purpose, the utility model provides a visual positioning system, which comprises an indicator light and a mounting component, the indicator light is installed on the mounting component, the indicator light is set to multiple, and the multiple indicator lights are arranged and combined to form an indicator symbol.

[0007] The indicator symbol is formed by the arrangement and combination of the indicator light. When the indicator light emits light, the indicator light combination forms a light mark. Compared with the shape and color recognition in the prior art, the light mark composed of light can be set to a smaller size.

[0011] The guide mark emitted by the ring-shaped indicator light is more convenient for calculating the positive center of the guide mark, thereby facilitating subsequent positioning.

[0012] Preferably, the indicator light arrangement combination is preferably formed into a circular shape.

[0013] Preferably, since the conventional infrared LED indicator light has problems such as uneven light emission and poor heat dissipation, the indicator light of the present application is a four-core LED lamp bead.

[0014] The indicator light is set to a four-core LED lamp bead, which has higher light emission efficiency, more uniform brightness, higher stability and longer service life, and stronger practicality.

[0015] Preferably, the mounting component is a PCB board.

[0016] Preferably, in order to achieve better heat dissipation effect, the PCB board is an aluminum-based PCB board.

[0017] Compared with the conventional PCB board, the aluminum-based PCB board has better heat dissipation effect, which can help to improve the service life of the indicator light.

[0018] The utility model discloses a second aspect provides a kind of visual guidance module, including camera module, control module and above-mentioned guide mark, the camera module is connected with the control module signal, the camera module is used to identify the guide mark.

[0021] The RTK module is set to cooperate with image recognition to complete positioning, and the positioning accuracy is higher.

[0022] The utility model discloses a third aspect of a kind of photovoltaic cleaning systems, including unmanned aerial vehicle, photovoltaic cleaning device and above-mentioned visual guidance module;

[0023] The unmanned aerial vehicle is configured with the camera module, and the photovoltaic cleaning device is provided with the guide mark.

[0024] Preferably, in order to realize the connection and release of the unmanned aerial vehicle and the photovoltaic cleaning device, the scheme further comprises a docking structure, the docking structure comprises a magnetic component and an electromagnet module, the magnetic component and the electromagnet module are arranged on the unmanned aerial vehicle and the photovoltaic cleaning device respectively, and the electromagnet module is adsorbed and connected with the magnetic component.

[0025] The magnetic component and the electromagnet module are adsorbed and connected, so that the unmanned aerial vehicle is connected with the photovoltaic cleaning device. When the magnetic component and the electromagnet module are separated, the unmanned aerial vehicle is separated from the photovoltaic cleaning device.

[0026] The beneficial effect of the utility model lies in: the scheme forms an indication symbol through the arrangement and combination of the indicator light. When the indicator light emits light, the indicator light combination forms a light identification. Compared with the shape and color identification in the prior art, the light identification formed by light can be set to be smaller in size. BRIEF DESCRIPTION OF DRAWINGS

[0032] In order to make the purpose, technical scheme and advantages of the embodiments more clear and obvious, the utility model is further described in detail below in combination with the drawings and embodiments. When the following description relates to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0033] In the present disclosure in the microblog, the orientation words such as "inner, outer" are defined according to the contour of the corresponding parts themselves unless otherwise indicated. The terms such as "first, second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance.

[0034] Example 1

[0035] The basics are as follows: Figure 1 As shown, a guide sign includes a mounting component 2 and an indicator light 1, with the indicator light 1 mounted on the mounting component 2. The indicator light 1 is an infrared indicator light 1, and more preferably, it is a four-core LED. The infrared indicator light 1 is easier to identify than other indicator lights 1, which helps improve identification accuracy. The mounting component 2 is specifically a PCB board; furthermore, to achieve better heat dissipation, the PCB board in this embodiment is preferably an aluminum-based PCB board.

[0036] In this embodiment, multiple indicator lights 1 are provided, and the specific number can be 10, 14, 24, or 30, etc. The number of indicator lights 1 is not limited. In this embodiment, the indicator lights 1 are arranged in a uniform manner, and the uniformly arranged indicator lights 1 form an indicator symbol.

[0037] In this embodiment, the indicator symbol is set as a ring. The ring-shaped indicator symbol makes it easier to calculate the exact center of the symbol, thereby improving the positioning accuracy.

[0038] It is understood that in this embodiment, the indicator lights 1 are arranged and combined to form a ring. However, in some other embodiments, the indicator lights 1 can also be combined to form other shapes of indicator signs, such as rectangles or ovals.

[0039] It is understood that in this embodiment, indicator symbols are formed by combining indicator lights 1. Compared with the conventional indicator symbols formed by combining symbols and colors in the prior art, the indicator lights 1 emit more conspicuous light, so even if the size of the guide sign is reduced, it can still achieve a more accurate indication effect, thus solving the shortcomings of the prior art.

[0040] Example 2

[0041] This embodiment provides a visual guidance module, such as Figure 2 As shown, it includes the guide sign, camera module 3 and control module 4 of embodiment 1.

[0042] In this embodiment, the camera module 3 and the control module 4 are in a signal-connected state. The camera module 3 includes a camera, which is used to capture images of the guide signs and feed these images back to the control module 4. In this embodiment, the control module 4 can be an industrial control computer module or other control modules. After the control module 4 receives the image captured by the camera, the control module 4 can perform positioning based on the image.

[0043] To improve positioning accuracy, this embodiment also includes an RTK module. The RTK module and the control module 4 are in a signal connection state. The RTK module and the camera module 3 cooperate with each other for positioning.

[0044] For example, when positioning is needed, first, the RTK module is used for preliminary positioning, and then when the camera module 3 is close to the guide mark to a predetermined distance, such as 10 meters, the camera module 3 is used to identify the guide mark to further improve the positioning accuracy. Alternatively, the RTK module is used for positioning, and when the positioning is about to be completed, the camera module 3 is used to identify the guide mark to determine whether the positioning is wrong.

The electromagnet module 52 is installed at the top of the photovoltaic cleaning device, and the electromagnet module 52 is an electromagnet device in the prior art.

[0049] For example, when the photovoltaic cleaning device needs to be transported, the magnetic component 51 hung by the unmanned aerial vehicle can be adsorbed to the electromagnet module 52 to realize the fixed connection of the unmanned aerial vehicle and the photovoltaic cleaning device. When the photovoltaic cleaning device needs to be released, the magnetic component 51 hung by the unmanned aerial vehicle is adsorbed to the electromagnet module 52 to separate the unmanned aerial vehicle from the photovoltaic cleaning device.

[0050] In order to ensure the docking success rate of the magnetic component 51 and the electromagnet module 52, the electromagnet module 52 is installed on the guide plate in the embodiment, and the electromagnet module 52 is located at the center position of the guide mark, as shown in Figure 4The center position of the guide mark is recognized by the camera arranged on the unmanned aerial vehicle, and then the magnetic component 51 is moved to the center position of the guide mark by the unmanned aerial vehicle, so that the magnetic component 51 and the electromagnet module 52 are accurately docked, and the docking success rate of the unmanned aerial vehicle and the photovoltaic cleaning device is improved.
