DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] Now, a shore-based integrated radar optoelectronic tracking device provided in an embodiment of the present application is described. Figure 1 , a shore-based integrated radar optoelectronic tracking device, including a controller 3, an optoelectronic component and a radar component.

[0026] The controller 3 is arranged on the base 1 . The base 1 is further provided with a metal stabilizing platform 2 . The controller 3 is embedded in the metal stabilizing platform 2 .

[0027] The top of the controller 3 is provided with a first motor 4, the top of the first motor 4 is connected with a first turntable 5, and a photoelectric component is provided on the first turntable 5. The first motor 4 drives the first turntable 5 to rotate, thereby driving the photoelectric component to rotate left and right.

[0028] Specifically, the optoelectronic component includes two symmetrically arranged fourth motors 6, one of which is connected to a visible light camera 9 via a rotating shaft 7, and the visible light camera 9 is arranged in the first cavity; the other fourth motor 6 is connected to an infrared camera 8 via another rotating shaft 7, and the infrared camera 8 is arranged in the second cavity. A light shield 10 is arranged on the top of the visible light camera 9 and the infrared camera 8. A temperature sensor 91 and a heating element 92 are arranged at the bottom of the first cavity where the visible light camera 9 is located.

[0029] Furthermore, the visible light camera 9 and the infrared camera 8 are both provided with anti-fog coatings.

[0030] The photoelectric component is divided into left and right wings, and the two wings can be driven independently; the left wing is a high-definition visible light camera 9 with anti-fog coating, which is driven to rotate by one of the fourth motors 6 connected to a shaft 7, and the shooting posture is adjusted up and down, which is responsible for collecting daytime image information; the right wing is a high-definition infrared camera 8 with anti-fog coating, which is driven to rotate by another fourth motor 6 connected to another shaft 7, and the shooting posture is adjusted up and down, which is responsible for collecting image information at night or under extreme weather conditions; the switching between the visible light camera 8 and the infrared camera 8 is controlled by the controller 3; the first cavity where the visible light camera 9 is located is embedded with a humidity sensor 91, which is responsible for monitoring the internal and external air humidity and uploading it to the controller 3. When the critical value is triggered, the heating unit 92 is started to evaporate the water vapor inside the visible light camera 9, reduce the frost fog of the visible light camera 9 to obtain high-quality images; the thermal infrared camera 8 mainly relies on the thermal radiation emitted by the object to form an image, and its image quality is less affected by water vapor condensation, so the humidity sensor and heating element are not set in the second cavity where the infrared camera 8 is located. A light shield 10 is provided on the top of the visible light camera 9 and the infrared camera 8 to reduce glare.

[0031] The optoelectronic component is connected to the second turntable 11 via a rotatable connecting shaft 17. The second turntable 11 is provided with a second motor 12, and the second motor 12 is connected to the radar component. The upper and lower ends of the connecting shaft 17 can rotate freely and independently, so that the radar component and the optoelectronic component are independent of each other when they are adjusted horizontally. The second motor 12 drives the second turntable 11 to rotate, thereby driving the radar component connected to the second motor 12 to rotate left and right, so as to adjust the radar component in the horizontal direction.

[0032] Specifically, the radar assembly includes a radar 15, which is connected to the third motor 14 through one end of a rotating rod 16. The third motor 14 is arranged on the right side wall of the support arm 13, and the other end of the rotating rod 16 is connected to the left side wall of the support arm 13 through a bearing; the bottom of the support arm 13 is fixedly connected to the second motor 12, and the third motor 14 drives the radar 15 to flip up and down.

[0033] The left and right sides of the rotating rod 16 are respectively mounted on the support arm 13 through bearings and the third motor 14. The radar 15 is arranged in the middle part of the rotating rod 16 and performs rapid scanning as the rotating rod 16 rotates. When the target enters the warning area and is captured by the radar 15, it is tracked to capture the position, speed, distance and other information of each target.

[0034] When the optoelectronic assembly is in use, the controller 3 starts the visible light camera 9 and / or the infrared camera 8 to collect target image information according to demand.

[0035] The controller 3 is used to control each motor and perform photoelectric posture calculation. When the radar 15 captures the target, the controller 3 calculates the angle at which the photoelectric component rotates to the target based on the known target information. The functions of the controller belong to the prior art. For example, the controller 3 performs photoelectric posture calculation, and the controller with the application publication number CN108582077A and the patent name of a controller in a method for controlling an intelligent service robot, or other controllers in the prior art that can realize photoelectric posture calculation can be used.

[0036] See also Figure 2 , Figure 3 The first turntable 5 includes an upper table 51 and a lower table 52 . The output shaft of the first motor 4 passes through the lower table 52 and is connected to the upper table 51 . The lower table 52 is fixedly arranged and connected to the housing of the first motor 4 .

[0037] The upper table 51 is connected to a rotatable upper triangular block 511 on its side. The upper triangular block 511 is inverted, with a solid structure at the bottom and a hollow structure at the top. Figure 6 , Figure 7 Such an arrangement enables the upper triangular block 511 to always be in an inverted state under the action of gravity. A lower triangular block 521 is fixedly arranged on the side of the lower table 52, and the lower triangular block 521 is arranged upright.

[0038] When the upper table 51 rotates counterclockwise, see Figure 4 , the upper triangular block 511 rotates to the left side of the lower triangular block 521, and the hard contact stops the rotation; when the upper table 51 rotates clockwise, see Figure 5 , the upper triangular block 511 rotates to the right side of the lower triangular block 521, and the rotation stops due to hard contact; with this structure, the rotation of the first turntable 5 can be made no more than 360°, thus avoiding the winding problem of the connecting wires between the controller 3 and the visible light camera 9, the infrared camera 8, and the radar 17, and greatly reducing the fault problems caused by line problems.

[0039] In the actual production of this application, the length of the base 1 is 504 mm, the height of the controller 3 is 260 mm, the length and width are both 404 mm, the length, width and height of the radar are all 294 mm, and the length, width and height of the visible light camera 9 and the infrared camera 8 are all 200 mm.

[0040] The present application provides a shore-based integrated radar optoelectronic tracking device, which combines a radar component and an optoelectronic component, is small in size, simplifies the layout and maintenance of the device, and realizes the tracking coordination of the radar component and the optoelectronic component on the target under the drive of the first motor and the second motor. At the same time, an anti-fog coating is used inside the visible light camera and the infrared camera, and a temperature sensor and a heating element are installed inside the visible light camera to prevent the visible light camera from generating fog and ensure the clarity of the visible light camera.

[0041] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
