In urban building fire early warning systems, it can regularly inspect densely populated areas of old buildings to promptly identify areas with abnormal temperatures caused by electrical aging, short circuits, and other problems. In post-earthquake life search and rescue operations, it can accurately locate the heat source of living beings, clearly perceiving the presence of life signs in rubble even at night or in low light conditions. In post-flood search and rescue operations, it can be mounted on drones or other equipment to comprehensively scan disaster areas and promptly identify the heat source of trapped individuals. The "dual-spectrum gimbal and real-time image transmission system" is existing technology. Model: Z-2Mini Intelligent 4K Full-Color Night Vision Mini Dual-Light Pod.

[0031] Working process of infrared thermal imaging intelligent inspection module 2:

[0032] 1. Data Collection

[0033] Image Capture: The target area is simultaneously captured using a 4K resolution visible light camera and a long-wave infrared uncooled thermal imaging camera within the dual-spectrum gimbal. The two cameras play different roles in different scenarios. In well-lit conditions, the visible light camera provides a clear image of the target area; in nighttime or low-light environments, the visible light camera, powered by the AI-ISP full-color night vision imaging engine, still achieves good full-color observation results, while the infrared thermal imaging camera focuses on capturing the temperature distribution of the target area.

[0034] Target Detection and Tracking: Leveraging the AI ​​multi-target detection and tracking capabilities of the dual-spectrum gimbal, the system intelligently identifies targets such as pedestrians and vehicles in the captured footage. During inspections, if a specific target is detected, such as a heat source of a living being in a life-saving search and rescue scenario, the pod can continuously lock onto and track it to ensure that the target is not lost.

[0035] 2. Data Transmission and Analysis

[0036] Real-time image transmission: The real-time image transmission system transmits visible light images and infrared thermal images captured by the dual-spectrum pan-tilt unit to the monitoring terminal in real time. Monitoring personnel can view the situation of the target area on the terminal in real time.

[0037] Abnormality analysis: At the monitoring terminal, the image transmitted back is analyzed using advanced infrared thermal imaging technology. In urban building fire warning, attention is paid to whether there are temperature abnormal areas caused by electrical aging, short circuit, etc.; in post-earthquake life search and rescue and post-flood personnel search, the main detection is whether there is a life heat source. Once an abnormal situation is found, the system will promptly issue an alarm.

[0038] 3. Result feedback and follow-up processing

[0044] When installing, the docking seat 3-3 is inserted from the rear side of the connecting seat 3-2 to the front, so that the connecting seat 3-2 is in contact with the rear side wall of the docking groove 3-3-1, at this time, the extension hole is aligned with the lock hole 3-3-2, and under the elastic force of the spring 3-4, the lock block 3-5 penetrates the extension hole and the lock hole 3-3-2 in turn, so as to connect the docking seat 3-3 and the connecting seat 3-2 together; when disassembling, the two lock blocks 3-5 are simultaneously squeezed to the middle by using a tool, the lock blocks 3-5 compress the spring 3-4, and when the lock blocks 3-5 are separated from the lock hole 3-3-2, the docking seat 3-3 is pulled out to the front, so that the docking seat 3-3 is separated from the connecting seat 3-2.

[0047] The working process of the intelligent air-drop transport module 4:

[0048] Preparation stage

[0049] 1. Material loading: The staff will place the urgently needed materials such as food, medicine, tents, etc. with a total weight not exceeding 5 kg in the material carrying part of the air-drop transport module. Ensure that the materials are securely fixed to avoid shaking or falling during transportation and dropping.

[0050] 2. Parameter setting: According to the specific location information of the disaster-stricken population concentration area or the designated location of the rescue personnel, such as latitude and longitude, altitude, etc., combined with the meteorological conditions (wind speed, wind direction, temperature, etc.) of the drop site, the control system accurately sets the throwing parameters of the air-drop transport module, including throwing strength, angle and time, to ensure that the throwing accuracy error is ≤0.5 m.

[0051] 3. System self-check: Before dropping, the system automatically conducts a comprehensive self-check on the crank slider-rudder linkage mechanical structure, checks whether the connection of each part is stable, the movement is smooth, and the electrical system and control system are working normally. Only when all self-check results are qualified, the module will enter the state of waiting for dropping.

[0052] Transportation phase

[0053] 1. Transport carrier movement: The transport carrier flies or moves according to the predetermined route and height to the target drop site. In the process of flight, real-time data from the navigation system and sensors are received and processed to ensure the accuracy and stability of the flight path.

[0054] 2. Real-time monitoring and adjustment: During transportation, the control system of the module continuously monitors its own state and environmental information such as attitude, speed, acceleration, etc. If there are changes in air flow, wind direction, etc., the system will automatically adjust the flight attitude and speed of the transport carrier according to the preset algorithm, and dynamically correct the throwing parameters to ensure that the materials can be accurately dropped.

[0055] Throwing phase

[0056] 1. Approach to target: When the transport carrier approaches the target drop site, the control system accurately calculates the throwing time according to the real-time position information and the preset throwing parameters. When reaching the optimal throwing point, the system issues a command to start the crank slider-rudder linkage mechanical structure.

[0057] 2. Material throwing: After receiving the command, the rudder starts to rotate, driving the crank slider mechanism to move. The crank slider mechanism converts the rotary motion of the rudder into linear motion, generating enough force to throw the materials out of the module. During the throwing process, the system will ensure that the materials fly to the target location along the predetermined trajectory according to the previously set throwing strength and angle.

[0058] 3. Precision control: During the material dropping process, the module may be equipped with high-precision positioning systems and sensors to monitor the flight trajectory and position of the material in real time. If the flight trajectory of the material deviates, the system will make timely adjustments by adjusting the remaining material dropping method or using the module's own attitude adjustment device to ensure that the final delivery precision error is ≤0.5m.

[0059] Homing phase

[0060] 1. Mechanical structure reset: After the material dropping is completed, the steering engine reverses and drives the crank slider mechanism back to the initial position. During the reset process, the system will accurately control the movement of the mechanical structure to ensure that each component is accurately homed, preparing for the next delivery.

[0061] 2. State feedback: After the module is homed, the system will feedback the current state information to the operator, including the position of the mechanical structure, the working state of the system, etc. The operator can judge whether the module is normally homed and whether it can perform the next material loading and delivery task according to the feedback information.
