Description

Technical Field

[0001] This utility model relates to the field of radar equipment technology, and in particular to an extension device for monitoring radar. Background Technology

[0002] Ground-based radar is a monitoring device used in fields such as emergency rescue and support, open-pit mine slope deformation, urban subsidence, and landslides. With the development of geological disaster monitoring technology, ground-based synthetic aperture radar is also widely used in the process of geological disaster monitoring.

[0003] However, existing ground-based radar systems do not provide ideal visualization of the monitored area, requiring experienced professionals for application and analysis. They cannot accurately correspond to the actual location information of the monitored area, making it difficult to quickly identify potential hazards. Therefore, depending on the application scenario, different performance indicators of optical sensors may be required for assistance, and functions such as optical 3D modeling also need to be completed by independent systems. Furthermore, GNSS data acquisition by ground-based radar is generally achieved using dedicated surveying equipment. Both of these tasks require human operation, and the acquired data also needs to be manually copied, stored, and processed. From the perspective of the application of ground-based radar systems, the level of system integration and automation is not high.

[0004] When deploying applications, the variety of equipment makes them inconvenient to carry and transport, especially in the emergency rescue industry where high efficiency and accuracy are required. The large number of equipment types also increases the probability of errors. Installing accessories involves using tools and screws to secure them, and then connecting the two parts of the equipment together with cables and connectors, making installation and disassembly time-consuming.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] like Figures 1 to 5 As shown, a radar monitoring extension device 100 includes a housing 1, two optical sensors 2, two GNSS positioning modules 3, and an interactive unit 4.

[0026] The housing 1 has an elongated structure, including an upper cover 11, a lower cover 12, and two cover plate assemblies 13. The upper cover 11 is made of plastic and has good electromagnetic wave penetration. Each end of the upper cover 11 has a window 111, and the front side has a first communication interface 112 and a power interface 113. The first communication interface 112 is used for external communication. The bottom of the lower cover 12 has a second communication interface 121 for communication with the main unit of the ground-based radar 200. The cover plate assembly 13 includes a cover plate 131 and a silicone cover 132. The cover plate 131 has a circular opening 1311 in the middle, and a sliding groove 1312 is provided around the side wall of the cover plate 131. The cover plate 131 slides onto the window 111 of the upper cover 11 via the sliding groove 1312. The opening 111 is connected to the sliding groove 1312 to increase the sealing effect. The lower end of the silicone cover 132 is movably hinged to the lower end of the cover plate 131. The upper end of the silicone cover 132 is provided with a buckle that is snapped onto the cover plate 131. The buckle includes a female buckle 1313 on the upper end of the cover plate 131 and a male buckle 1321 on the upper end of the silicone cover 132. By pressing the male buckle 1321 on the upper end of the silicone cover 132, it can be snapped onto the female buckle 1313 for sealing and fixation. The silicone cover 132 can be used to protect the camera of the optical sensor 2. A support piece 14 is provided inside each of the two ends of the housing 1. The support piece 14 abuts against the front and rear sides of the housing 1. In order to reduce weight, the upper cover 11 is made of non-metallic material, and the support piece 14 plays a supporting and reinforcing role to prevent the upper cover 11 from deforming. An indicator light 15 is provided at the bottom of the housing 1 to indicate the working status of the extension device 100. The side wall of the housing 1 is provided with heat dissipation holes 16 for heat dissipation of the internal components of the housing 1. The bottom of the housing 1 is provided with a quick-release connector 17, which can realize quick installation and disassembly with the ground-based radar 200.

[0027] The two optical sensors 2 are disposed inside the housing 1, and the camera of the optical sensor 2 is correspondingly disposed in the circular opening 1311 of the cover plate 131. The optical sensor 2 is generally a camera. Cameras have different focal lengths and the size of the camera will be different. Depending on the optical sensor installed, the cover plate assembly 13 with a circular opening 1311 of different sizes can be selected and installed on the window 111. The cover plate assembly 13 only needs to slide on the window 111 of the upper cover 11 through the sliding groove 1312, which is simple and convenient to replace and supports tool-free replacement. This realizes the selection of different configurations of the optical sensor 2, which to a certain extent expands the application range of the expansion device 100 and meets the customization needs of different customers.

[0028] The two GNSS positioning modules 3 are installed inside the housing 1 and are located at opposite ends of the housing 1.

[0029] The interactive device 4 is communicatively connected to the optical sensor 2 and the GNSS positioning module 3.

[0030] The housing 1 has a long strip structure, which is more conducive to the two optical sensors 2 to perform three-dimensional optical modeling and also helps the two GNSS positioning modules 3 to improve positioning accuracy.

[0031] The expansion device 100 features a lightweight design and incorporates multiple sensors with a compact structure. Optical sensor replacement is quick and easy, supporting tool-free replacement and convenient portability. It provides a platform for expanding the capabilities of ground-based radar, including rapid optical modeling and GNSS positioning. The optical modeling function digitizes the monitoring area, reproducing a virtual space. Using GNSS positioning information, the radar monitoring results are registered with the digital twin model of the monitoring area, resulting in rich and highly visualized monitoring effects. This effectively improves the applicability of the visualized portable ground-based radar application and supplements and enriches its functionality.

[0032] This invention integrates the optical sensor 2 and the GNSS positioning module 3 within the expansion device 100, providing rapid optical modeling and GNSS positioning capabilities for the ground-based radar 200. It features a compact structure, high integration, and ease of portability and transportation. A first communication interface 112 allows for external communication during standalone applications, while a second communication interface 121 enables internal communication with the ground-based radar 200 during integrated applications. A cover plate assembly 13 slides onto the window 111, allowing for quick replacement of the cover plate assembly to accommodate different optical sensor models, simplifying the process. This invention is a simple, integrated radar expansion device with a high degree of system automation, enabling rapid component replacement, tool-free installation, and easy portability.
