Description

Technical Field

[0001] The present invention belongs to the technical field of alarm devices, and more specifically, particularly relates to a quick-disassembly and assembly multifunctional alarm fire rescue detection device. Background Art

[0002] Fire rescue alarm equipment refers to a series of equipment that can automatically or manually send out alarm signals to notify the fire department, relevant rescue personnel and surrounding personnel when a fire or other emergency occurs. These devices are an important part of the fire safety system. Their main function is to transmit danger information in a timely and accurate manner, buy time for rescue, and reduce losses caused by fire. Existing fire rescue alarm equipment includes the following structures: 1. Visible light imaging: Visible light imaging devices in existing technologies, such as digital cameras and smart phones, mainly rely on CCD or CMOS sensors to capture visible light, convert it into electronic signals, and then process and display it.

[0003] 2. Thermal imaging: Thermal imaging technology usually uses an infrared focal plane array (FPA detector) to capture the thermal radiation of the target and convert it into electrical signals to generate images.

[0004] 3. 5G backward compatibility: 5G backward compatibility technology provides faster data transmission speeds and lower network latency than 3G.

[0005] 4. Real-time video transmission: Existing real-time video transmission technologies such as HLS and NDI rely on different encoding algorithms and network protocols.

[0006] Beidou Positioning: As one of the global satellite navigation systems, the Beidou system provides high-precision positioning services.

[0007] The Chinese patent publication number is: CN218784266U, a fire communication device and a helmet. The fire communication device of this embodiment can free hands, and can provide real-time feedback of audio and video information of the rescue scene, which can effectively improve the efficiency of rescue communication.

[0008] Existing fire rescue alarm equipment has the following disadvantages: 1. Existing equipment has separate visible light imaging and thermal imaging devices, and their data formats and transmission methods may be different. If you want to use both types of imaging data to analyze the fire and find trapped people at the same time, you need to switch between different display devices or software platforms, which not only wastes time, but is also prone to errors in emergency situations; 2. In addition to imaging equipment, it is also necessary to carry a variety of independent equipment such as gas detection equipment and manual alarm equipment. These devices have different shapes, sizes and mounting methods. It is difficult to carry them all on the body effectively and ensure that they will not fall or be damaged during the operation. There are certain limitations.

[0009] In view of this, the existing structure and defects are studied and improved, and a quick-disassembly and assembly multifunctional alarm fire rescue detection device is provided, in order to achieve the purpose of having more practical value. Summary of the invention

[0025] Working principle: In the first step, the firefighter turns on the helmet equipment, the battery in the battery compartment 14 supplies power to each module (such as the SOS button 11, the visible light lens 15, the thermal imaging lens 16, etc.), the circuit main board 62 is initialized, and the self-check is performed to see whether each component is working normally, including checking whether the lens can shoot normally, whether the human detector 3 and the gas detector 4 can collect data normally, whether the display screen 2 can display normally, and whether the speaker 13 and the communication microphone 6 can communicate normally. At the same time, the display screen 2 has a touch screen function, and the control of each structure is realized through touch screen control; In the second step, the visible light lens 15 and the thermal imaging lens 16 work simultaneously. The visible light lens 15 captures visible light images of the surrounding environment, and the thermal imaging lens 16 collects infrared thermal images of objects and transmits image data to the circuit main board 62.

In the high-intensity firefighting work, firefighters may have abnormal heart rate or decreased blood oxygen saturation due to excessive physical exertion, inhalation of harmful gases, etc. The module can quickly detect these changes and issue an alarm to ensure the life safety of firefighters; The device integrates a visible light lens 15 and a thermal imaging lens 16 to simultaneously obtain conventional visible light images and infrared thermal images. In firefighting scenes, the visible light lens 15 is used to clearly observe scene details under normal light conditions, such as building structures and equipment appearances, while the thermal imaging lens 16 can play a key role in thick smoke and dark environments to discover hidden fire sources, overheated equipment, or trapped personnel. This multifunctional perception method enables firefighters to have a more comprehensive understanding of the surrounding environment and greatly improves their ability to respond to complex fire scenes. The device integrates the gas detection circuit mainboard 62, the nuclear radiation detection module 44 and the gas detection sensor 45 through the gas detector 4, and can simultaneously detect the concentration and nuclear radiation level of multiple harmful gases. At the fire scene, in addition to the threats of flames and high temperatures, the leakage of harmful gases and the possible nuclear radiation risks are also huge safety hazards. This integrated detection function enables firefighters to perceive danger in advance and take corresponding protective measures; In the third step, after receiving the data from each module, the circuit main board 62 processes and integrates the data. For example, the image data of the visible light lens 15 and the thermal imaging lens 16 are synthesized or switched to be displayed on the display screen 2. The firefighter's physical condition is judged based on the data of the human body detector 3. The surrounding environment is judged based on the data of the gas detector 4 whether there is excessive harmful gas or abnormal nuclear radiation. At the same time, combined with the position information of the positioning module 61, the processed information is displayed in real time on the display screen 2, including the picture taken by the lens, physical condition indicators, gas and radiation detection results, etc.; Step 4: If the circuit board 62 finds dangerous conditions such as high temperature and high pressure, abnormal human health indicators, excessive harmful gases or abnormal nuclear radiation during data processing, the circuit board 62 will trigger the speaker 13 to sound an alarm. At the same time, the mobile network connected by the SIM card in the SIM card slot 52 sends data related to the dangerous situation to the command center, and the firefighters can also communicate with the command center or teammates through the communication microphone 6 to report the on-site situation or receive instructions; The device is equipped with a SIM card slot 52, so that the helmet can access the mobile network. This function realizes real-time data transmission between the device and the command center or other related platforms. Firefighters can send various information on the scene (such as environmental data, their own health status, etc.) to the command center in a timely manner, and can also receive instructions and feedback from the command center, thereby ensuring the circulation of information and the efficiency of command. In the fifth step, if the data in the helmet device needs to be displayed on a larger screen, the data can be transmitted to an external display device through the HDMI interface 5, and the Type-C interface 51 can be used to connect other devices for data transmission or charging, such as transmitting the collected data to a computer for more detailed analysis; The device is provided with an HDMI interface 5 and a Type-C interface 51. The HDMI interface 5 is convenient for transmitting images and data acquired by the helmet to an external large-screen display for on-site command decision-making or post-analysis. In addition to being used for charging, the Type-C interface 51 can also be used for data transmission, and can transmit data in the device to other devices for storage, analysis and other operations, thereby increasing the flexibility of data interaction. The device provides a quick way for firefighters to ask for help in dangerous situations through the SOS button 11. When encountering an emergency situation such as being trapped or injured, by pressing the SOS button 11, the device can send a distress signal through the network or other communication methods, and the signal contains positioning information, which is convenient for rescue personnel to quickly locate, greatly improving the survival probability of firefighters in dangerous environments; This device uses the speaker 13 as an alarm output device and works in coordination with various detection modules.
