Description

Technical Field

[0001] This utility model relates to the field of personal protective equipment for firefighters, and in particular to a firefighter distress call device with image transmission function. Background Technology

[0002] According to relevant national and industry standards such as GB / T 29178, XF621, and XF622, firefighter distress calls are essential equipment for firefighters during firefighting and rescue operations and are mandatory. All firefighters participating in firefighting and rescue operations must wear them. However, currently, firefighter distress calls have relatively limited functionality, generally only providing audible and visual alarms. Firefighters also need to carry individual image transmission devices during firefighting and rescue operations, typically carried and used by communication support personnel or fire reconnaissance personnel. These devices require handheld infrared thermal imagers and various detection devices. The large number of these devices, each with relatively limited functionality, not only increases the quantity and weight of equipment carried by firefighters but also complicates firefighting and rescue operations when multiple devices are used simultaneously, increasing the burden on firefighters and hindering real-time observation of the fire scene. Therefore, there is an urgent need for a firefighter distress call device with image transmission capabilities to solve these problems. Utility Model Content

[0003] The present invention aims to provide a firefighter distress call device with image transmission function to solve the problems of heavy usage burden, inconvenience of use and insufficient integration of functions of existing fire-fighting equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The basic technical solution provided by this utility model is as follows: a firefighter distress call device with image transmission function, including a distress call device housing, a top cover, and a back clip housing. The top cover is equipped with a display screen and a communication module. The top cover is mounted on the distress call device housing, which is equipped with a distress call button. The distress call device housing is equipped with an audio-visual module, an image module, an integrated module, a main control chip, and a power supply component. The main control chip interacts with the display screen, audio-visual module, image module, integrated module, and communication module, and controls their corresponding actions. The audio-visual module includes a directional indicator light and a buzzer. The directional indicator light passes through a through hole on the top cover and is located on its surface. The communication module is located to one side of the directional indicator light. The image module includes an infrared thermal imaging camera and a low-light visible light camera. The infrared thermal imaging camera and the low-light visible light camera are mounted in a through hole on the back of the distress call device housing. The integrated module includes a sensor component, a positioning component, and a communication component.

[0006] Preferably, the sensor assembly includes a motion sensor, a high-precision barometric pressure sensor, and a gyroscope, and the positioning assembly uses a Bluetooth AOA / AOD module and a multi-mode GNSS for joint positioning.

[0007] Preferably, an external interface board is provided inside the distress call device housing. The external interface board is electrically connected to the main control chip. The interface end of the external interface board is located at the through hole on the side of the distress call device housing. A sealing cover is provided on the through hole on the side of the distress call device housing.

[0008] Preferably, a sealing ring is provided between the distress call device housing and the top cover, and a camera protective plate is provided on the back of the distress call device housing.

[0009] Preferably, the distress call device housing is adapted to the back clip housing, the back clip housing is provided with a slot, the slot is adapted to a locking block, and the locking block is set on the back clip plate.

[0010] Preferably, the back clip housing is provided with a protrusion, which is located on the side of the emergency call button.

[0011] The basic technical solution's principle and beneficial effects are as follows: Images are acquired through an infrared thermal imaging camera and a low-light visible light camera. After processing by the main control chip, the real-time images are displayed on a screen. The system can switch between infrared and visible light imaging depending on the fire situation. Firefighters can view the real-time images on the screen for ease of use, and the images are transmitted to the command center in real-time via a communication component, facilitating their understanding of the fire situation. The communication module collects and transmits sound, which is then processed by the communication component and the main control chip to transmit wireless signals, facilitating communication between firefighters and with the command center. Sensor components can monitor the movement of firefighters; when firefighters are moving normally... The directional indicator light remains constantly lit. When the sensor component detects that a firefighter has not moved for 30 seconds, it issues an alarm. The main control chip then controls the directional indicator light to flash infrared and visible light, simultaneously activating a buzzer to produce a sound. This, along with the positioning component, helps locate the trapped firefighter, allowing other firefighters to quickly find them. Additionally, the distress call device is mounted near the firefighter's shoulder, close to their ear. The buzzing sound can help rouse an unconscious firefighter, improving their survival rate. When in danger, firefighters can also press the distress call button to activate the distress function, further enhancing the device's functionality. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-4 As shown: A firefighter distress call device with image transmission function includes a distress call device housing 1, a top cover 2, and a back clip housing 16. The top cover 2 is equipped with a display screen 3 and a communication module 14. The top cover 2 is mounted on the distress call device housing 1. A distress call button 4 is located on the distress call device housing 1. Inside the distress call device housing 1 are a sound and light module 7, an image module 8, an integrated module 9, a main control chip 10, and a power supply assembly 12. The main control chip 10 interacts with the display screen 3, the sound and light module 7, the image module 8, the integrated module 9, and the communication module 14. And control its corresponding actions; the sound and light module 7 includes a directional indicator 701 and a buzzer 702. The directional indicator 701 passes through the through hole on the top cover 2 and is located on its surface. The communication module 14 is located on one side of the directional indicator 701; the image module 8 includes an infrared thermal imaging camera 801 and a low-light visible light camera 802. The infrared thermal imaging camera 801 and the low-light visible light camera 802 are installed in the through hole on the back of the distress caller housing 1; the integrated module 9 includes a sensor assembly 901, a positioning assembly 902 and a communication assembly 903.

[0019] The specific implementation process is as follows:

[0020] In use, by operating the display screen 3, the infrared thermal imaging camera 801 and the low-light visible light camera 802 on the image module 8 are turned on. The distress call device is then attached to the firefighter's clothing. In the fire scene or other rescue location, the image module 8 captures images and can switch between infrared and visible light imaging according to the situation. The image module 8 transmits the data to the main control chip 10, which processes it and then wirelessly transmits the image to the command center via the communication component 903. This allows the command center to observe and understand the situation and better direct the firefighters on site. After the open flame is extinguished, the firefighters can remove the distress call device and turn on the display screen 3 to view the infrared image captured by the infrared thermal imaging camera 801 in real time. This allows them to observe the scene and check for any remaining internal fire points or other scattered, hidden fire points, facilitating the monitoring of residual fires. During fire rescue operations, firefighters can activate the communication module 14 by pressing the button on the side of the distress call device housing 1, allowing them to communicate with teammates and other personnel. The command center communicates and coordinates; during fire rescue operations, the sensor component 901 in the integrated module 9 monitors the firefighters' movement status in real time. When they are moving normally, the main control chip 10 controls the directional indicator 701 on the sound and light module 7 to remain constantly lit, serving as a warning of their location. When the sensor component 901 detects that a firefighter has not moved for thirty seconds, it issues an alarm feedback, which is transmitted to the main control chip 10. The main control chip 10 then controls the directional indicator 701 to flash infrared and visible light, and activates the buzzer 702 to emit a buzzing sound. In complex environments, the infrared flashing light allows for better detection by infrared thermal imaging worn by other teammates, improving search efficiency. At the same time, the positioning component 902 locates trapped firefighters, and the communication component 903 wirelessly transmits the signal to their teammates and the command center, facilitating the rapid locating of trapped firefighters. Furthermore, when a firefighter is in danger, pressing the distress call button 4 can quickly activate the alarm without waiting for movement monitoring. Compared to traditional simple sound and light distress call devices, its functions are more integrated and comprehensive.

[0021] In this embodiment, the sensor component 901 includes a motion sensor, a high-precision barometric pressure sensor, and a gyroscope. The positioning component 902 uses a Bluetooth AOA / AOD module and multi-mode GNSS for joint positioning. The motion sensor can monitor the movement status of firefighters and determine whether their movement is normal. The high-precision barometric pressure sensor can detect minute changes in air pressure, and the accuracy of converting these changes into altitude changes can reach ±0.1 meters. If a drop in altitude exceeding a threshold (e.g., more than 3 meters) is detected within a short period (e.g., 0.5-2 seconds), the gyroscope can detect whether the firefighters are experiencing physical imbalance, and determine whether they have stepped into a hole or fallen from a height. This information is then fed back to the main control chip 10 to determine whether to issue an alarm. When conducting fire rescue outdoors, multi-mode GNSS satellite positioning can accurately locate the firefighters in open areas. When conducting indoor rescue, multi-mode GNSS may fail. The Bluetooth AOA / AOD module is used to calculate the signal direction by phase difference and combine it with the movement signals of each firefighter to locate them, providing basic data support for the rescue.

[0022] In this embodiment, an external interface board 11 is provided inside the distress call device housing 1. The external interface board 11 is electrically connected to the main control chip 10. The interface end of the external interface board 11 is located at the through hole on the side of the distress call device housing 1, and a sealing cover 5 is provided on the through hole on the side of the distress call device housing 1. The sealing cover 5 can seal the external interface to prevent water ingress or blockage; the external interface board 11 allows the distress call device to be connected to other devices for functional expansion.

[0023] In this embodiment, a sealing ring 13 is provided between the distress call housing 1 and the top cover 2, and a camera protective plate 6 is provided on the back of the distress call housing 1. The sealing ring 13 can prevent water from entering the distress call, increase its reliability, and extend its service life.

[0024] In this embodiment, the distress call housing 1 is adapted to the back clip housing 16. The back clip housing 16 is provided with a slot 17, which is adapted to a locking block 19. The locking block 19 is disposed on the back clip plate 18. By snapping the back clip housing 16 onto the distress call housing 1, the two can be connected. Through the cooperation of the locking block 19 and the slot 17, the back clip plate 18 can be quickly connected to the back clip housing 16. The back clip plate 18 allows the distress call to be conveniently and securely mounted on the firefighter, facilitating the firefighter's equipment.

[0025] In this embodiment, a protrusion 15 is provided on the back clip housing 16, and the protrusion 15 is located on one side of the emergency call button 4. The protrusion 15 is slightly higher than the emergency call button 4, which can prevent the emergency call button 4 from being accidentally squeezed, causing a false alarm and wasting resources.
