Description

Technical Field

[0001] This utility model relates to the field of drone detection, and in particular to a 5G explosion-proof drone detection terminal. Background Technology

[0002] With the rapid development of the low-altitude economy, the widespread adoption of drone technology and the surge in the risk of "black flights" have created a sharp contradiction. For Zone 1 / 2 explosive-prone areas such as petrochemical plant oil storage tank areas and the vicinity of oil-immersed transformers in substations, the threat of "black flights" by drones is particularly deadly—they may carry ignition sources and cause explosions, or steal production data or collide with precision instruments by carrying equipment. Once an accident occurs, it will cause economic losses of hundreds of millions of yuan and major casualties. After the opening of low-altitude airspace, the number of consumer-grade and industrial-grade drones has exploded. "Black flight" incidents frequently occur in explosive-prone areas such as substations, petrochemical plants, and core areas of large-scale events, causing equipment shutdowns, explosion hazards, and information leaks. In order to avoid safety hazards caused by drones, it is necessary to use detection equipment to detect drones. Currently, drone detection technologies are mainly divided into three categories: radar detection, optical detection, and radio frequency detection. However, both methods have fatal flaws when used in explosive-related locations, specifically: Existing equipment is completely inadequate to meet the above requirements: traditional low-speed, small radars use ordinary aluminum alloy shells with low protection levels, failing to isolate flammable and explosive gases and dust in explosive environments; their internal power supplies lack intrinsic safety measures, and the radio frequency modules operate at high energy levels, far exceeding the safety thresholds specified in standards, making them highly susceptible to becoming ignition sources. Relying on a single sensing dimension results in numerous detection blind spots: radar systems have short detection ranges for DIY plastic drones and cannot distinguish between birds and small drones, leading to a high false alarm rate; optical detection systems experience a sharp decline in image quality at night or in dense fog, resulting in poor detection performance. Utility Model Content

[0003] The main purpose of this utility model is to provide a 5G explosion-proof drone detection terminal, which can effectively solve the problems of low overall protection strength, poor explosion-proof effect, small detection range and poor detection effect.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A 5G explosion-proof drone detection terminal includes a base. A DMR antenna is fixedly installed on one side of the base. A battery, a 5G communication module, a Beidou positioning module, a Bluetooth module, a detection module, and a DMR communication module are fixedly installed inside the base. The DMR communication module is electrically connected to the battery, signal connected to the DMR antenna, and signal connected to a noise reduction circuit. A cover is fixedly installed at one end of the base. A detection component is embedded in the outer wall of the cover, and a protective cover is snapped onto the outer wall of the cover. The detection component is signal connected to the detection module. The 5G communication module, the Beidou positioning module, the Bluetooth module, the detection module, and the DMR antenna are all electrically connected to the battery. The 5G communication module communicates bidirectionally with an external 5G base station. The Bluetooth module is electrically connected to the battery and signal connected to the detection module, and is used to connect to external Bluetooth peripherals and transmit detection data. The base and the cover are made of explosion-proof alloy material.

[0005] Preferably, the overall protection level of the base and the cover is IP68, and the whole machine has passed ExibIICT4Gb explosion-proof certification.

[0006] Preferably, the 5G communication module supports SA / NSA dual-mode 5G network, the detection module is bidirectionally connected to the 5G communication module, and the UAV detection data processed by the detection module is transmitted to the 5G communication module.

[0007] Preferably, the detection component includes an NFC mounting plate, an expansion interface, a main camera, a macro camera, a night vision light, a night vision camera, a flash, a thermal imaging module, and a radio frequency sensor. The radio frequency sensor covers the 2.4G / 5.8G frequency band. In conjunction with the main camera, the night vision camera, and the thermal imaging module of the detection module, it can detect mainstream drones, FPV racing drones, and DIY drones. The NFC mounting plate is fixedly connected to the cover. The expansion interface, the main camera, the macro camera, the night vision light, the night vision camera, the flash, the thermal imaging module, and the radio frequency sensor are all fixedly connected to the NFC mounting plate. The expansion interface is electrically connected to the battery and signal connected to the detection module, respectively, for powering external devices and transmitting data.

[0008] Preferably, the battery is an intrinsically safe high-density lithium polymer battery that meets the ExibIICTGb explosion-proof standard.

[0009] Preferably, the base is equipped with an integrated noise reduction circuit, which is connected to the 5G communication module and the DMR communication module respectively.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The entire unit has passed the ExibIICT4Gb explosion-proof certification. The base and cover are made of explosion-proof alloy materials and have an IP68 protection explosion-proof sealing ring design. The battery is intrinsically safe and meets the same level of explosion-proof standards. During power supply, the radio frequency energy is ≤0.019mJ and the surface temperature is ≤135℃. It can operate stably for a long time in Zone 1 / 2 explosion-proof environments, solving the pain point of traditional equipment being "easy to cause ignition and explosion" and avoiding equipment downtime or safety accidents.

[0011] 2. By integrating detection components and employing four-mode detection—visible light (main camera / macro camera), infrared (night vision camera / night vision light), thermal imaging, and radio frequency—along with the feature fusion algorithm of the detection module, the detection probability of mainstream consumer drones, FPV racing drones, and DIY plastic drones is improved. The detection range is stable and long. In low-light environments at night or when drones are "silently cruising," the thermal imaging module can capture thermal radiation signals, solving the problem of missed detections in traditional single detection methods and improving detection accuracy.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-4As shown, a 5G explosion-proof drone detection terminal includes a base 1. A DMR antenna 5 is fixedly installed on one side of the base 1. Inside the base 1, a battery 2, a 5G communication module 3, a Beidou positioning module 4, a Bluetooth module, a detection module 800, and a DMR communication module are fixedly installed.

The 5G communication module 3, Beidou positioning module 4, Bluetooth module, detection module 800, and DMR antenna 5 are all electrically connected to the battery 2. The 5G communication module 3 communicates bidirectionally with an external 5G base station. The dental module is electrically connected to battery 2 and signal-connected to detection module 800, and is used to connect to external Bluetooth peripherals and transmit detection data. The base 1 and cover 6 are made of explosion-proof alloy material, and the overall protection level of the base 1 and cover 6 is IP68. The whole machine has passed ExibIICT4Gb explosion-proof certification. Battery 2 is an intrinsically safe high-density lithium polymer battery that complies with the ExibIICT4Gb explosion-proof standard. 5G communication module 3 supports SA / NSA dual-mode 5G network. Detection module 800 and 5G communication module 3 are connected bidirectionally. The drone detection data processed by detection module 800 is transmitted to 5G communication module 3. The base 1 has an integrated noise reduction circuit, which is signal-connected to 5G communication module 3 and DMR communication module 9.

[0016] The detection module 800 transmits structured detection data, including terminal location, drone information, and timestamps, to the 5G module via a bidirectional signal connection with the 5G communication module 3. Leveraging the SA / NSA dual-mode network support of the 5G communication module 3 and the existing 5G base station in the factory area, data can be uploaded to the factory security management platform in real time without the need for a dedicated transmission link. This significantly reduces deployment costs and allows the remote control center to quickly and accurately monitor the dynamics of unauthorized drone flights, preventing sensitive information leaks or production safety risks caused by drone intrusion. Simultaneously, the entire system connects via Exi... With bIICT4Gb explosion-proof certification, the base 1 and cover 6 are made of explosion-proof alloy materials with an IP68 protection level, which can effectively isolate flammable and explosive gases and dust in Zone 1 / 2 explosion-prone environments such as oil storage tank areas in petrochemical plants. At the same time, the battery 2 is an intrinsically safe high-density lithium polymer battery that meets the ExibIICT4Gb explosion-proof standard. There is no radio frequency energy exceeding the standard or surface high temperature hazard during power supply. It avoids ignition risks from both electrical and physical perspectives, ensuring long-term stable operation of the equipment in high-risk environments and avoiding accidents such as explosions and equipment shutdowns caused by equipment problems.

[0017] Example 2 like Figure 5As shown, in one embodiment, the detection component 8 includes an NFC mounting plate 801, an expansion interface 802, a main camera 803, a macro camera 804, a night vision light 805, a night vision camera 806, a flash 807, a thermal imaging module 808, and a radio frequency sensor. The radio frequency sensor covers the 2.4G / 5.8G frequency band. In conjunction with the main camera 803, night vision camera 806, and thermal imaging module 808 of the detection module 800, it can detect mainstream drones, FPV racing drones, and DIY drones. The NFC mounting plate 801 is fixedly connected to the cover 6.

The expansion interface 802 is electrically connected to the battery 2 and signal connected to the detection module 800, respectively, for powering external devices and transmitting data.

[0018] By integrating a main camera 803, a night vision camera 806, a thermal imaging module 808, and a radio frequency sensor covering the 2.4G / 5.8G frequency bands into the detection component 8, multi-dimensional detection collaboration can be achieved. During the day, the main camera 803 captures the visible light characteristics of the drone. At night / in low light environments, the night vision light 805 is triggered to work with the night vision camera 806 to collect infrared images. At the same time, the thermal imaging module 808 captures the thermal radiation signals of the drone's motor and battery 2. Even when facing "silent" DIY drones or small plastic target drones, it can accurately locate them through thermal features or radio frequency signals, effectively solving the problems of traditional detection methods. Addressing the issue of low detection probability in low-light environments, for small targets, and for silent drones, this device can reliably detect mainstream drones, FPV racing drones, and DIY drones, improving detection reliability across all scenarios. The expansion interface 802 of the detection component 8 is electrically connected to the battery 2 and signal-connected to the detection module 800, providing power to external devices and enabling data interaction between them. It can be expanded to include functions such as "drone deterrence" and "long-distance precise ranging" according to actual needs, without requiring modifications to the main terminal structure, significantly improving the device's functional adaptability and meeting the differentiated prevention and control needs of different scenarios.

[0019] Working principle: Install the device in the designated location and fully charge or continuously power battery 2. During operation, intrinsically safe battery 2 provides safe power to each module to avoid excessive radio frequency energy and maintain a surface temperature ≤135℃. The detection component, through visual detection of "main camera 803 + night vision camera 806 + thermal imaging module 808" and radio frequency detection with radio frequency sensor, works in conjunction with detection module 800 to achieve multi-source data acquisition from mainstream drones, FPV racing drones, and DIY drones, with a stable detection distance ≥1.5km. The data processed by detection module 800 is transmitted via bidirectional signal from 5G communication module 3. The device can upload data to the management platform in real time using an external 5G base station without the need for additional transmission links. Simultaneously, the DMR communication module connects to the DMR antenna 5 and the noise reduction circuit integrated within the base 1, enabling on-site personnel to communicate over a private network and reducing noise interference in the industrial environment. The Bluetooth module connects to the detection module 800 to support data transmission from external Bluetooth peripherals, while the expansion interface 802 allows for the connection of external devices for functional expansion. With a power consumption of ≤20W and a weight of ≤1kg, the device can be fixedly installed in explosion-proof cabins or quickly deployed in mobile modular units, meeting the diverse prevention and control needs of explosive-related locations.
