Description

Technical Field

[0001] This utility model relates to the field of wireless image transmission reconnaissance equipment technology, and in particular to a hand-thrown wireless image transmission reconnaissance equipment. Background Technology

[0002] With the increasing demand for reconnaissance and monitoring missions in high-temperature environments from industries, military, and emergency rescue sectors, existing hand-launched wireless image transmission reconnaissance equipment often faces technical bottlenecks in practical applications, failing to operate stably for extended periods in extreme high-temperature environments. High-temperature environments severely test the internal electronic components, battery systems, and sensing modules of the equipment. Traditional battery systems, in particular, have limited heat resistance and are prone to performance degradation, insufficient battery life, or even thermal runaway under high-temperature conditions, leading to safety risks such as explosions and fires.

[0003] Current image acquisition equipment used in high-temperature environments primarily relies on traditional chemical batteries or external power sources. However, in scenarios such as fire scenes, desert areas, or high-temperature industrial zones, deploying external power sources is impractical, and battery life is extremely limited, preventing the equipment from completing long-term image acquisition and stable transmission tasks. This problem is particularly prominent in critical missions such as fire reconnaissance, environmental monitoring, and military observation, seriously impacting emergency response and personnel safety.

[0004] Therefore, there is an urgent need for a hand-launched wireless image transmission reconnaissance device that can adapt to extreme high-temperature environments, has long-term working capability, and does not require traditional battery power, so as to achieve true self-powered, remote monitoring and stable operation. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of this invention is to provide a hand-launched wireless image transmission reconnaissance device, comprising: a high-temperature resistant shell for protecting internal functional components in high-temperature environments, the high-temperature resistant shell being made of a high-temperature resistant material and possessing compressive strength and corrosion resistance; a thermoelectric power generation device for converting thermal energy from an external heat source into electrical energy through the Seebeck effect, the thermoelectric power generation device comprising: a hot end for absorbing heat from the external heat source; a cold end isolated from the external heat source, thereby creating a temperature difference between the hot end and the cold end and outputting electrical energy; a control module for controlling the operating status of the device; a wireless image transmission module for transmitting acquired image data to a remote receiving terminal in real time; and a heat insulation structure for suppressing the conduction of external heat to the cold end to maintain a stable cold end temperature, thereby ensuring continuous electrical energy output from the thermoelectric power generation device.

[0006] In one possible implementation, the high-temperature resistant shell includes a base layer made of titanium alloy, the outer surface of which is covered with a ceramic thermal barrier coating to enhance heat resistance and improve the overall corrosion resistance of the shell.

[0007] In one possible implementation, the hot end of the thermoelectric power generation device forms thermal contact with an external heat source via a heat-conducting channel disposed on the high-temperature resistant outer shell. The heat-conducting channel is made of a highly thermally conductive material to improve heat transfer efficiency.

[0008] In one possible implementation, a thermally conductive interface material is provided between the heat-conducting channel and the hot end to reduce thermal resistance and improve heat transfer efficiency.

[0009] In one possible implementation, the cold end is surrounded by a multi-layer insulation structure, which includes a ceramic fiber layer and a polyurethane foam layer to suppress external heat conduction to the cold end.

[0010] In one possible implementation, the cold end is thermally connected to a metal heat sink disposed inside the insulation structure. The metal heat sink is used to release the residual heat generated by the cold end to the low-temperature cavity side in order to maintain the cold end temperature stability.

[0011] In one possible implementation, the wireless image transmission module includes an infrared imaging unit and an image transmission unit. The infrared imaging unit is used to acquire image data of a high-temperature area, and the image transmission unit is used to transmit the image data in real time as a video stream to a remote receiving terminal.

[0012] In one possible implementation, the image transmitting unit supports image compression coding and multi-channel concurrent transmission to improve data transmission stability in high-temperature or strong interference environments.

[0013] In one possible implementation, the control module is connected to an infrared sensor signal and is used to identify the location or direction of the target heat source based on the infrared thermal imaging signal, and to control the image acquisition area to cover the target area.

[0014] In one possible implementation, multiple fixed-mount cameras are also included to simultaneously acquire image data from multiple angles and transmit the image data to a remote receiving terminal.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Based on the above technical solution, this utility model provides a hand-launched wireless image transmission reconnaissance device comprising a high-temperature resistant shell, a thermoelectric power generation device, a control module, a wireless image transmission module, and a heat insulation structure. The high-temperature resistant shell is made of high-temperature resistant material to protect internal functional components in high-temperature environments. The thermoelectric power generation device converts the thermal energy of an external heat source into electrical energy through the Seebeck effect, providing continuous power to the device. The control module manages the operating status. The wireless image transmission module enables remote real-time transmission of image data. The heat insulation structure maintains a stable cold-end temperature and improves thermoelectric efficiency. The synergistic effect of these structures allows the device to operate stably and continuously supply power even in high-temperature environments, ensuring the continuity and reliability of image acquisition and transmission. By integrating efficient thermoelectric conversion and thermal isolation design, the device possesses the ability to operate autonomously without external power supply, while ensuring complete transmission of image data in high-interference and high-heat scenarios, improving the overall practicality and security of the system. This effectively solves the problems of power interruption, system instability, and poor image transmission faced by existing image acquisition devices in high-temperature or extreme environments.

[0027] Figure 1 A schematic diagram of the internal structure of a hand-launched wireless image transmission reconnaissance device provided in an embodiment of this utility model; Figure 2 This is a schematic diagram of an image transmission system; Figure 3 This is a schematic diagram showing the linkage between control module 5 and the infrared sensor.

[0028] Please see Figure 1-2In one possible implementation, a hand-launched wireless image transmission reconnaissance device includes a high-temperature resistant shell 1, a thermoelectric power generation device 2, a control module 5, a wireless image transmission module 6, and a heat insulation structure 7. The high-temperature resistant shell 1 is made of materials with high melting points, strong corrosion resistance, and good mechanical strength (such as titanium alloys and ceramic composites), and is used in high-temperature environments such as steel smelting furnaces, boiler inspection areas in thermal power plants, deep geothermal exploration wells, and fire rescue operations, effectively isolating the internal components from heat radiation and high-pressure gases. The thermoelectric power generation device 2 includes a hot end 3 and a cold end 4. The hot end 3 faces an external high-temperature heat source and rapidly absorbs heat through a thermally conductive interface material 9 (such as graphite sheets). The cold end 4 is isolated from the environment by a high-efficiency heat insulation layer, establishing a stable temperature difference between the cold end 4 and the hot end 3, thereby utilizing the Seebeck effect to stably output electrical energy. The control module 5 coordinates and controls the image acquisition, processing, compression, and wireless transmission processes, ensuring the system responds on demand and maintains a high energy efficiency ratio. The wireless image transmission module 6 integrates an infrared imaging sensor and a communication chip to quickly transmit captured images to a remote terminal in the form of a data stream, enabling real-time monitoring and data retention in high-temperature operating environments. The equipment is surrounded by a multi-layered heat insulation structure 7, effectively preventing ambient heat from affecting the cold end 4, thereby ensuring the long-term, stable operation of the power generation system.

[0029] This device achieves remote image monitoring through thermoelectric conversion and wireless communication. Specifically, the thermoelectric power generation device 2 uses the Seebeck effect driven by the temperature difference between the hot end 3 and the cold end 4 to generate a voltage in the conductive material, thereby continuously powering the device. This is particularly suitable for high-risk, high-temperature environments where conventional power sources cannot be accessed. In the image acquisition stage, the infrared imaging component captures thermal images of the target area, which are then compressed and encoded under the command of the control module 5, and the image data is transmitted to the backend in real time by the wireless image transmission module 6. This process is especially important in metallurgical furnace inspection, internal gas pipeline inspection, internal inspection of petrochemical cracking towers, and fire rescue scenarios, ensuring that operators can obtain real-time image information without entering dangerous areas. At the fire rescue site, the device can quickly determine the distribution of the fire source, fire intensity, and high-temperature areas through infrared imaging technology, ensuring the safe distance for search and rescue personnel, while providing accurate heat source information to effectively guide the direction of firefighting. The thermal insulation structure 7 adopts a multi-layer composite thermal insulation design, which effectively isolates the interference of external high temperature on cold end 4, maintains the temperature difference between hot end 3 and cold end 4, provides stable working conditions for the thermoelectric power generation module, and thus realizes the self-powered closed-loop operation of the equipment in a high-temperature environment.

[0030] This equipment integrates thermoelectric power generation, a high-temperature resistant structure, and a wireless image acquisition and transmission module, enabling image monitoring without an external power supply. This significantly expands its applicability in extreme industrial environments. Specifically, in ultra-high-temperature environments such as steelmaking, aluminum electrolysis, and glass melting furnaces, the equipment can operate long-term without requiring a maintenance-free power supply system, significantly reducing the frequency and cost of manual intervention. The equipment achieves contactless image acquisition, improving operator safety. Through infrared imaging and real-time image stream transmission technology, maintenance personnel can obtain equipment status and anomaly warnings immediately, improving emergency response efficiency. The high-temperature resistant shell and composite insulation design ensure stable operation in harsh environments, demonstrating strong environmental adaptability. The thermoelectric power generation module requires no fuel or external energy, making it environmentally friendly and suitable for the widespread application of high-temperature waste heat recovery monitoring systems. In fire rescue scenarios, the equipment's high stability and self-powered capability ensure that rescue teams can continuously rely on it for real-time monitoring of high-temperature areas. Especially at large-scale fire disaster sites, the equipment effectively reduces the risk to on-site personnel, provides accurate heat source location, and improves rescue efficiency and safety.

[0031] In one possible implementation, the high-temperature resistant outer shell 1 consists of a titanium alloy substrate layer, with its outer surface covered by a ceramic thermal barrier coating to enhance the structural stability and corrosion resistance of the equipment in high-temperature environments. Titanium alloy itself possesses high strength, high-temperature resistance, and corrosion resistance, making it suitable for long-term application in harsh environments. The ceramic thermal barrier coating effectively isolates heat transferred from external heat sources. It is primarily composed of zirconium oxide, alumina, or their composites, and the coating method can be plasma spraying or thermal spraying, ensuring it adheres tightly to the metal surface to form a robust thermal barrier layer.

[0032] When the equipment is in a high-temperature environment, external heat flow first acts on the ceramic coating. The low thermal conductivity of the ceramic layer allows it to reflect and block a large amount of heat from entering, acting as the first line of thermal insulation. Even if residual heat is conducted to the underlying titanium alloy substrate, its excellent high-temperature mechanical properties are sufficient to resist thermal stress and physical deformation, maintaining the stability of the entire structure. This combination of two layers significantly reduces the heat transfer rate and improves the overall heat resistance limit, making it particularly suitable for blast furnace inspection, external monitoring of chemical reactors, and mobile monitoring equipment in fire accidents.

[0033] In terms of material selection, titanium alloys can be replaced with other alloys possessing high strength and high-temperature stability, such as nickel-based alloys or stainless steel, depending on specific requirements. The material of the outer ceramic coating can also be adjusted according to the target temperature and environmental corrosivity. For example, rare-earth stabilized zirconia coatings can be used to improve long-term thermal stability, or multi-layered composite structures can be introduced to adapt to dynamic thermal shock environments. Furthermore, in terms of process implementation, in addition to thermal spraying, laser cladding or sol-gel methods can also be used to construct the ceramic layer to meet the technical requirements of different equipment manufacturing processes.

[0034] Please see Figure 1 In one possible implementation, the hot end 3 of the thermoelectric power generation device 2 forms thermal contact with an external heat source through a heat-conducting channel 8 disposed on the high-temperature resistant outer casing 1. The heat-conducting channel 8 is made of a highly thermally conductive material to improve heat transfer efficiency. This heat-conducting channel 8 is typically made of materials such as copper, aluminum, or graphite, which have good thermal conductivity and can quickly and effectively transfer heat from the external heat source to the hot end 3. The design of the heat-conducting channel 8 can be optimized according to actual needs, for example, by increasing the surface area or changing the shape of the channel to further improve heat transfer efficiency.

[0035] In practical applications, the heat conduction channel 8 efficiently transfers heat from the heat source to the hot end 3. The hot end 3 absorbs heat from the external environment, creating a thermoelectric electromotive force between itself and the cold end 4, thus realizing the thermoelectric power generation process. The hot end 3 is designed to be in close contact with the external heat source, ensuring full heat absorption and improving thermoelectric conversion efficiency. The material and shape of the heat conduction channel 8 can be adjusted according to different high-temperature environments to achieve optimal heat transfer, making it suitable for high-temperature environments such as metallurgy and high-temperature power generation.

[0036] The advantage of this design lies in its ability to significantly improve the thermal energy conversion efficiency of the thermoelectric power generation device 2 by optimizing the materials and structure of the heat conduction channel 8. The high thermal conductivity material allows the hot end 3 to quickly acquire heat, reducing heat loss and effectively improving the device's self-powering capability. Especially in fire rescue or other high-temperature emergency scenarios, the device can operate continuously and efficiently without relying on an external power source, ensuring uninterrupted on-site monitoring and data transmission.

[0037] In one possible implementation, a thermally conductive interface material 9 is provided between the thermally conductive channel 8 and the hot end 3 to reduce thermal resistance and improve heat transfer efficiency. The thermally conductive interface material 9 can be a flexible graphite pad, thermally conductive silicone grease, phase change material, or metal foil layer, etc. These materials have good thermal conductivity and can fill the microscopic gaps between the contact surfaces of the thermally conductive channel 8 and the hot end 3, effectively eliminating thermal resistance problems caused by uneven contact and ensuring efficient heat transfer from the thermally conductive channel 8 to the hot end 3.

[0038] In high-temperature applications, such as industrial heat treatment furnaces, pipeline thermal monitoring, or fire emergency sites, the application of thermally conductive interface material 9 is particularly crucial. Because the structural assembly of equipment may contain minor misalignments or interface deformation caused by thermal expansion, simple metal-to-metal contact is insufficient to achieve ideal heat conduction. Introducing thermally conductive interface material 9 enhances the continuity of the heat flow channel while maintaining close contact, ensuring thermal stability at the thermal contact surface even after thermal shock or prolonged operation.

[0039] This structure improves the overall thermal response speed of the system, enabling the hot end 3 to reach its operating temperature more quickly and establish a stable temperature difference. This is beneficial for the thermoelectric power generation device 2 to achieve rapid start-up and stable operation in scenarios with transient high temperatures or drastic temperature fluctuations. The selection of the thermal interface material 9 can also be optimized according to the temperature limits, chemical stability, and mechanical compliance under different environments to meet a wider range of high-temperature equipment integration needs.

[0040] Please see Figure 1 In one possible implementation, the outer periphery of the cold end 4 is covered with a multi-layered thermal insulation structure 10 to suppress external heat conduction to the cold end 4, thereby maintaining its low temperature state. The thermal insulation structure 10 includes a ceramic fiber layer and a polyurethane foam layer. The ceramic fiber layer is close to the surface of the cold end 4 and has excellent high-temperature thermal insulation performance, capable of withstanding ambient temperatures up to 1000°C and effectively blocking radiation and conductive heat. The polyurethane foam layer is wrapped on the outside, mainly providing porous thermal insulation and a certain degree of mechanical cushioning protection.

[0041] In practical operation, the thermoelectric power generation device 2 relies on the temperature difference between the hot end 3 and the cold end 4 to continuously output electrical energy. However, maintaining the low temperature of the cold end 4 under high-temperature environments is extremely challenging. By covering the cold end 4 with a multi-layer insulation structure 10, the thermal interference from external heat sources can be significantly reduced, allowing the temperature of the cold end 4 to remain within a stable range for extended periods. Ceramic fiber materials can withstand short-term high-temperature impacts, while polyurethane foam forms an additional thermal insulation buffer on the outer layer of the structure, helping to slow down the heat conduction rate and improve the overall durability and environmental adaptability of the insulation structure 10.

[0042] This structure is particularly suitable for equipment exposed to prolonged heat, such as pipeline crossing monitoring devices, high-temperature storage status monitoring nodes, or fire emergency communication relay equipment. In these applications, the stable performance of the multi-layer insulation system allows the cold end 4 to continuously participate in thermoelectric power generation, preventing energy supply interruptions due to rapid increases in ambient temperature, thereby ensuring the continuous operation of critical functions such as monitoring and image transmission.

[0043] In terms of materials, different types of ceramic fibers (such as alumina ceramic fibers and aluminosilicate ceramic fibers) can be selected and combined with polyurethane foam layers of different densities according to the specific thermal environment level. The thickness of the insulation layer can also be adjusted to adapt to space constraints to ensure a compact structure and stable performance.

[0044] Please see Figure 1 In one possible implementation, the cold end 4 is thermally connected to a metal heat sink 11 disposed inside the insulation structure 10. The metal heat sink 11 is used to guide the residual heat generated by the cold end 4 to the low-temperature cavity side for release, thereby maintaining the temperature stability of the cold end 4. The heat sink is generally made of copper, aluminum, or composite thermally conductive alloy materials, possessing high thermal conductivity and good heat diffusion capability. Its shape can be finned, porous, or arranged in a ring to enhance the heat dissipation area and heat convection efficiency.

[0045] During equipment operation, although the cold end 4 is insulated, it may still gradually accumulate heat due to internal heat conduction or prolonged operation. The metal heat sink 11, by being tightly connected to the cold end 4, forms a low thermal resistance channel, which quickly transfers excess heat to the cavity space in the lower temperature region and releases it through natural convection or radiation, thereby preventing the temperature of the cold end 4 from rising too quickly and affecting the temperature difference conditions for thermoelectric power generation.

[0046] This structure is particularly suitable for equipment operating continuously for extended periods under high-temperature conditions, such as downhole temperature recorders, boiler wall monitoring modules, or wireless relay nodes deployed at fire accident sites. The introduction of the metal heat sink 11 effectively improves the system's thermal balance capability, enabling the cold end 4 to maintain a lower operating temperature, thereby ensuring a stable and continuous Seebeck effect in generating output voltage.

[0047] The heat sink can be installed using threaded connections, press-fitting, or thermally conductive adhesive bonding to adapt to different structural design requirements. Depending on actual heat dissipation needs, the area and thickness of the heat sink can be adjusted, or a microchannel structure can be used to improve heat diffusion capabilities. Furthermore, the overall heat dissipation efficiency can be further enhanced by combining this with the spatial layout of the cryogenic cavity.

[0048] Please see Figure 1-3In one possible implementation, the wireless image transmission module 6 includes an infrared imaging unit 12 and an image transmission unit 13. The infrared imaging unit 12 is used to acquire image data of the high-temperature area, and the image transmission unit 13 is used to transmit the image data to a remote receiving terminal in real time as a video stream. The infrared imaging unit 12 uses a high-sensitivity infrared sensor, which can clearly capture images of heat sources in high-temperature environments and obtain thermal radiation information of the high-temperature area through the sensor's detection area. The image transmission unit 13 compresses and encodes these thermal imaging image data and transmits them to the remote monitoring system in real time as a video stream via a wireless communication network (such as Wi-Fi, LoRa, or 5G networks), ensuring that remote personnel can obtain on-site heat source images in a timely manner for further analysis and decision-making.

[0049] In application, the wireless image transmission module 6 plays a crucial role in areas such as fires, high-temperature industrial zones, and monitoring of thermal power equipment. Especially in fire rescue scenarios, the infrared imaging unit 12 can quickly pinpoint the precise location of the fire source, the development of the fire, and the temperature distribution of the surrounding environment, providing rescue personnel with safe and effective escape routes and firefighting strategies. The image transmission unit 13 ensures that the command center can understand the situation on-site in real time through remote transmission, allowing for timely adjustments to the rescue plan.

[0050] Furthermore, the image transmission unit 13 can be equipped with an intelligent compression algorithm that dynamically adjusts the image quality and compression ratio based on network bandwidth conditions during transmission, ensuring stable video transmission even in environments with limited bandwidth or strong interference. The wireless communication module supports multi-channel concurrent transmission to ensure efficient and stable data transmission even in complex environments.

[0051] In one possible implementation, the image transmission unit 13 supports image compression coding and multi-channel concurrent transmission to improve the transmission stability of image data under high temperature or strong interference environments. The image compression coding section can integrate efficient image encoding and decoding algorithms, such as H.264, H.265, or AV1 standards, which can significantly reduce data size while maintaining image clarity, thereby alleviating the burden on wireless transmission bandwidth. The compression process is completed in real time through a hardware encoder or embedded algorithm module, ensuring high synchronization between image acquisition and transmission.

[0052] Multi-channel concurrent transmission mechanisms allow image data to be transmitted in segments simultaneously across multiple communication channels. For example, a frame of image can be divided into several data packets and transmitted in parallel across multiple frequency bands or antenna paths, thereby improving overall throughput and enhancing anti-interference capabilities. This technology is particularly suitable for environments with strong electromagnetic interference, metallic shielding, or high thermal radiation, such as metallurgical smelting areas, oil and gas well exploration, nuclear power plant maintenance areas, and the interior of building structures at fire scenes.

[0053] In these complex operating conditions, traditional single-channel transmission methods often face problems such as data packet loss, latency, or image stuttering. However, the multi-channel concurrent function of the image transmission unit 13 can automatically select the optimal channel or dynamically switch among multiple paths to ensure that critical image information is continuously and completely transmitted to the backend. Combined with compression coding mechanisms, the image stream still has good adaptability and transmission stability even in environments with poor network conditions.

[0054] The image sending unit 13 can also be equipped with a built-in cache management module and a packet loss retransmission mechanism to improve fault tolerance, and support edge processors to perform preliminary analysis and intelligent distribution of images, further improving remote response efficiency.

[0055] In one possible implementation, the control module 5 is connected to the infrared sensor signal and is used to identify the location or direction of the target heat source based on the infrared thermal image signal, and to control the image acquisition area to cover the target area. The control module 5 receives the thermal image signal from the infrared sensor, analyzes and identifies areas with higher temperatures in the image, which may represent potential heat sources such as fire sources, overheated equipment, or other hazardous areas. Based on the infrared thermal image data, the control module 5 can calculate the precise location and direction of movement of the heat source and automatically adjust the viewing angle or focal length of the image acquisition unit to ensure that the target heat source is always within the image acquisition range.

[0056] This automatic tracking function plays a crucial role in scenarios such as fire rescue, industrial high-temperature detection, and equipment fault diagnosis. For example, in fire rescue, control module 5 can automatically identify flames or high-temperature areas and adjust the position of the equipment or the angle of camera 14 to ensure real-time capture of the fire source and changes in fire intensity. This function improves the accuracy and efficiency of on-site monitoring, enabling the remote command center to make decisions and carry out corresponding emergency responses more quickly.

[0057] Furthermore, control module 5 can also collaborate with other sensors (such as temperature sensors and gas sensors) to perform diversified data fusion analysis, enabling a more comprehensive assessment of heat sources in the target area. This data can then be used for intelligent adjustments to the image acquisition area, ensuring that the monitoring equipment always provides the clearest images in the most critical areas, avoiding any potential risks being overlooked.

[0058] In one possible implementation, a hand-launched wireless image transmission reconnaissance device further includes multiple sets of fixedly mounted cameras 14 for simultaneously acquiring image data from multiple angles and transmitting the image data to a remote receiving terminal. These cameras 14 can comprehensively monitor the same target area from different directions and viewing angles, thereby providing multi-dimensional image information. These cameras 14 generally employ high-resolution infrared or visible light sensors, enabling them to adapt to working requirements in extreme environments and ensuring that image quality is not affected by high temperature, high humidity, or strong interference.

[0059] The deployment of multiple cameras 14 can effectively solve the blind spot problem of traditional single-view monitoring. For example, at a fire scene, multiple cameras 14 can be deployed in different building corners or hard-to-reach areas to acquire information such as the location of the fire source, the direction of fire spread, and smoke concentration in real time, providing a more comprehensive on-site image. The images captured by these cameras 14 are transmitted in real time to a remote monitoring terminal via a wireless transmission module. Command center personnel can make quick decisions and allocate firefighting resources and personnel based on image data from different angles.

[0060] Furthermore, the multiple cameras 14 can automatically adjust their viewing angle or focal length according to the instructions of the control module 5 to cope with different environmental changes or target dynamics. For example, when a new heat source or temperature anomaly is detected, the control module 5 can automatically instruct the relevant cameras 14 to adjust their angles and lock onto the target area in real time to ensure the acquisition of critical image data. The flexible arrangement and automatic adjustment capability of the cameras 14 enable the device to have stronger adaptability and emergency response capabilities in complex and variable high-temperature environments.

[0061] Please see Figure 1 In one possible implementation, a hand-launched wireless image transmission reconnaissance device further includes multiple sets of fixedly installed cameras 14 for simultaneously acquiring image data from multiple angles and transmitting the image data to a remote receiving terminal. These cameras 14 can comprehensively monitor the same target area from different directions and viewing angles, thereby providing multi-dimensional image information. These cameras 14 generally employ high-resolution infrared or visible light sensors, enabling them to adapt to working requirements in extreme environments and ensuring that image quality is not affected by high temperature, high humidity, or strong interference.
