Description

Technical Field

[0001] This utility model relates to the technical field of fire-fighting equipment, and in particular to a fire rescue command device. Background Technology

[0002] In traditional fire and rescue systems, firefighters dispatched to a fire scene for reconnaissance, firefighting, and other operations can only communicate with the command center via police walkie-talkies. However, due to the complexity of fire scene conditions and the multitude of emergencies, firefighters may be unable to promptly request assistance from the command center after encountering danger, thus missing the optimal rescue opportunity. At the same time, the command center cannot obtain real-time and dynamic information about the situation of the firefighters, and commanders cannot provide precise instructions, preventing the command system from functioning at its maximum potential.

[0003] Therefore, Chinese patent CN2899322Y discloses a multi-point wireless distress call device for firefighters in fire scenes. When firefighters wear the handset to enter a fire scene or accident site for disaster reconnaissance, fire fighting and rescue, and disaster relief, once they encounter a dangerous situation that threatens their personal safety, the handset will manually or automatically send out continuous alarm sound signals, location flashing signals, and alarm working status radio signals. The commander of the main unit can confirm that the firefighter is in danger based on the alarm working status radio signals received by the main unit and can immediately dispatch rescue personnel to provide assistance.

[0004] However, this device can only provide rescue after firefighters are in danger, and cannot provide advance evacuation. Furthermore, the sub-unit and main unit are separate, making storage and retrieval inconvenient. Moreover, the device cannot monitor the real-time location of individual firefighters; in large factory areas with complex road networks, firefighters may get lost and encounter danger during emergency evacuations, making it difficult to return to safety.

[0027] After adopting the above technical solution, using this fire rescue command equipment, firefighters can quickly retrieve the sub-units from the cabinet and wear them when entering the scene for rescue and firefighting. The command box and main unit can be placed in a safe and open area, allowing the commander to conduct command from a safe location. By setting up main and sub-slots, each walkie-talkie can be conveniently stored and preserved. Moreover, the cover can be closed onto the cabinet to form a portable command box. In the event of a fire, the command box and multiple walkie-talkies inside can be quickly carried to the scene, preventing any walkie-talkies from being lost. After opening the cover, firefighters can accurately and quickly retrieve and wear each sub-unit, making it convenient and quick to use, saving time in putting on equipment, and facilitating efficient firefighting.

[0028] The firefighters' handset can not only communicate with the main unit in real time, but also detect the temperature and gas concentration in the fire scene. Once the temperature or gas is abnormal, the alarm module of the handset will be triggered to issue an audible and visual alarm to remind the firefighters to evacuate. In addition, the handset can also transmit the data detected in the fire scene to the command box. The commander can use the display screen to judge the ambient temperature and ambient gas concentration in the area where each firefighter is located and predict in advance whether there are risks such as combustion and explosion. In other words, the commander can notify the firefighters to take evacuation in advance.

[0029] The firefighter's sub-unit can also detect the firefighter's stationary state, meaning it can detect whether the firefighter is moving. If it detects that the firefighter has remained still for a certain period, it can determine that the firefighter may have fainted due to inhaling harmful gases or fallen to the ground due to other accidents. At this point, the control module will trigger the alarm module to issue an audible and visual alarm, and simultaneously transmit a rescue signal to the command box. The commander can then promptly dispatch search and rescue personnel to the scene. Furthermore, the sub-unit's audible and visual alarm can alert other firefighters or rescue personnel to quickly locate the fallen firefighter, thereby improving rescue efficiency and firefighter safety.

[0030] Furthermore, the display screen can show a real-time map of the rescue site, and in conjunction with the sub-unit's position detection module, it allows commanders to easily observe the positions of firefighters on the map, facilitating overall command and control. This includes directing firefighters to attack the fire or guiding them through evacuation routes. The laser module emits a directional laser beam into the sky. During an emergency evacuation, firefighters can follow the direction of this directional laser beam to avoid getting lost. Attached Figure Description

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] like Figures 1 to 11 As shown, a fire rescue command device in this embodiment includes a command box 100 and several walkie-talkies 200;

[0046] The walkie-talkie 200 includes a main unit 201 and multiple sub-units 202 capable of communicating with each other; in this embodiment, the sub-units 202 can realize the detection of firefighters' stationary status, ambient temperature, ambient gas concentration, firefighters' location, and sound and light alarms.

[0047] The main unit 201 may have the same structure as the sub-unit 202, or it may only have an intercom function. Firefighters carry the sub-unit 202 with them when entering the fire scene, while the main unit 201 is located in a safe area and carried by the commander to facilitate communication with teammates attacking the fire scene.

[0048] The command box 100 includes a box body 101 and a cover 102, and the command box 100 is equipped with a display module 20, an information module 30, a map module 40, a laser module 50 and a wireless module 60, which are electrically connected to the command and control module 10 respectively. The command and control module 10 is wirelessly connected to the wireless module 90 of the slave unit 202 through the wireless module 60, and is used to receive and display the data detected by the slave unit 202.

[0049] The top surface of the housing 101 is recessed with a main compartment 103 and several sub-compartments 104. The main compartment 103 is used to hold the main unit 201, and each sub-compartment 104 is used to hold the sub-units 202. The cover 102 is hinged to one side of the top surface of the housing 101. By setting the main compartment 103 and sub-compartments 104, each walkie-talkie 200 can be conveniently stored. Moreover, the cover 102 can be closed onto the housing 101 to form a portable command box 100. In the event of a fire, the command box 100 and the multiple walkie-talkies 200 inside can be quickly carried to the scene without any walkie-talkies 200 being lost. After opening the cover 102, firefighters can accurately and quickly take out each sub-unit 202 for wearing. It is convenient and quick to use, saving time in putting on equipment and facilitating efficient firefighting.

[0050] The display module 20 is a display screen 21 installed on the cover 102; the information module 30 is used to record the ambient temperature and ambient gas concentration detected by each sub-unit 202; the map module 40 is used to pre-store map data; the map data in the map module 40 can be pre-stored according to the city where the firefighter is located. For example, map data of all key fire-fighting units in the city can be pre-entered and corresponding fire-fighting plans can be set for easy access later. Of course, this map data can also be integrated in real time with the map and positioning functions of existing navigation software.

[0051] The display module 20's screen 21 displays data recorded by the information module 30 on the left and a rescue site map 41 on the right, simultaneously marking the positions of each sub-unit 202 on the rescue site map 41. Each sub-unit 202 represents a firefighter teammate. By displaying the ambient temperature and ambient gas concentration of each firefighter's environment on the screen 21, the commander can promptly determine whether each firefighter is in a dangerous environment. For example, the commander can determine whether the temperature at the firefighter's location is too high, whether there is a high concentration of flammable gas in the gas, whether the explosion limit has been reached, etc. Once a dangerous factor is detected, the commander can use the main unit 201 to issue a targeted and rapid warning, calling the corresponding firefighter to evacuate, preventing the firefighter from falling into danger, improving the safety of the fire rescue process, and protecting the lives of firefighters.

[0052] Furthermore, the display screen 21 can also display the rescue site map 41 in real time, and in conjunction with the firefighters' positions detected by the sub-unit 202, it can facilitate the commander to observe the positions of each firefighter on the rescue site map 41, making it convenient to coordinate and command, direct firefighters to surround the fire scene or guide firefighters to retreat routes, etc.

[0053] The laser module 50 is used to emit a directional laser beam into the sky. Therefore, in the event of an emergency and during evacuation, firefighters can follow the direction of this directional laser beam to avoid getting lost. Typically, this directional laser beam can illuminate up to 10 kilometers above the ground.

[0054] In summary, by using this fire rescue command equipment, firefighters can quickly take out the sub-unit 202 from the box 101 and wear it when entering the scene for rescue and firefighting. The command box 100 and the main unit 201 can be placed in a safe and open area, and the commander can conduct command from a safe location.

[0055] The firefighter's handheld device 202 can not only communicate with the main unit 201 in real time, but also detect the temperature and gas concentration in the fire scene. Once the temperature or gas is abnormal, the handheld device 202 will issue an audible and visual alarm to remind the firefighters to evacuate. In addition, the handheld device 202 can also transmit the data detected in the fire scene to the command box 100. The commander can predict in advance whether there is a risk of combustion or explosion based on the ambient temperature and ambient gas concentration of each firefighter's area. In other words, the commander can notify the firefighters to take precautions in advance.

[0056] The firefighter's sub-unit 202 can also detect the firefighter's stationary state, that is, whether the firefighter is in motion. When it detects that the firefighter has remained still for a certain period of time, it can be determined that the firefighter may have fainted due to inhaling harmful gases or fallen to the ground due to other accidents. At this time, the sub-unit 202 will issue an audible and visual alarm and transmit a rescue signal to the command box 100. The commander can then promptly dispatch search and rescue personnel to the scene. Moreover, the audible and visual alarm of the sub-unit 202 can alert other firefighters or rescue personnel to promptly discover the fallen firefighter, so as to find the fallen person in a complex fire scene with dense smoke in time, thereby improving rescue efficiency and firefighter safety.

[0057] In this embodiment, the command and control module 10 includes a control board 11 and several control buttons 12 located on the top surface of the housing 101. Each control button 12 includes a single-person evacuation button 121, a full evacuation button 122, and a laser control button 123. Each control button 12 is electrically connected to the control board 11, and the control board 11 is electrically connected to each module inside the command box 100. Each single-person evacuation button 121 corresponds to a sub-unit 202 and is used to independently control whether the corresponding sub-unit 202 plays an evacuation alarm. The full evacuation button 122 is used to control whether all sub-units 202 play an evacuation alarm. When the commander observes changes in the fire scene environment, he can press the single-person evacuation button 121 as needed to make the corresponding sub-unit 202 issue an evacuation alarm to remind the firefighters in the corresponding area to evacuate. When the fire scene collapses or the fire spreads, the full evacuation button 122 can also be pressed to remind all firefighters to evacuate in an emergency.

[0058] Compared to calling for evacuation via intercom, by setting a single-person evacuation button 121 and a full evacuation button 122 on the command box 100, and enabling the sub-unit 202 to issue a dedicated evacuation alarm, firefighters can be reminded to evacuate more quickly and accurately.

[0059] The laser control button 123 is used to control whether the laser module 50 emits laser light. The commander presses the laser control button 123 as needed to turn on the laser.

[0060] In this embodiment, the top surface of the housing 101 is recessed with multiple front-to-back side-by-side internal attack group areas 105. In this embodiment, there are three internal attack group areas 105, and each internal attack group area 105 has three sub-slots 104 spaced apart from left to right. That is, there are nine walkie-talkie 200 handsets 202 in the housing 101, which can be numbered 1-9 and can be used by three internal attack teams. Each internal attack team includes three teammates. A single retreat button 121 is provided on the front side of each sub-slot 104. Each teammate can bind their identity to the handset 202 in each sub-slot 104 in advance, and the information column of the corresponding handset 202 displayed on the display screen 21 can be accompanied by the corresponding teammate's name.

[0061] The command and control module 10 also includes multiple group retreat buttons 124 corresponding to the number of internal attack group zones 105. Each group retreat button 124 is distributed one-to-one with each internal attack group zone 105. The group retreat button 124 is used to trigger whether each sub-unit 202 in the corresponding internal attack group zone 105 plays a retreat alarm. Thus, by additionally setting up group retreat buttons 124, all teammates in the relevant area can be retreated simultaneously.

[0062] In this embodiment, the command box 100 may also be equipped with a face detection module 70; the face detection module 70 includes a face recording module 71, a camera 72 disposed on the cover 102, and a trigger switch 73 disposed in each sub-slot 104. The face recording module 71 is electrically connected to the command and control module 10, the trigger switch 73, and the camera 72; each trigger switch 73 will automatically trigger the face recording module 71 after the sub-machine 202 in the sub-slot 104 is removed, and the face recording module 71 controls the camera 72 to detect and record the face.

[0063] Therefore, the sub-unit 202 does not need to be bound to the identity of the firefighter in advance. When the firefighter takes the sub-unit 202, the trigger switch 73 will be automatically triggered. At the same time, the camera 72 will capture and record the corresponding facial image, so that the firefighter's face can be bound to the corresponding sub-unit 202 among 1-9. The corresponding facial image can also be sent to the command and control module 10 through the facial recording module 71, and then transmitted and displayed on the display screen 21 through the command and control module 10. The facial image can then be associated with the corresponding sub-unit 202, which is convenient for the commander to observe, judge and call.

[0064] The trigger switch 73 adopts existing technology, and the figure shows a schematic diagram. The trigger switch 73 can be an elastic contact structure such as a spring pin or a spring sheet. When the slave device 202 is taken out from the slave container 104, the trigger switch 73 can be automatically triggered, making it more convenient to use.

[0065] Furthermore, both the main container 103 and the sub-container 104 can be equipped with a container charging device 106, and both the main unit 201 and the sub-unit 202 are equipped with a walkie-talkie charging device 203. The container charging device 106 and the walkie-talkie charging device 203 cooperate to charge the containerized main unit 201 and sub-unit 202.

[0066] The charging slot 106 and the walkie-talkie charging device 203 can be connected via Type-C / USB interfaces, wireless charging modules, or magnetic charging structures similar to those between wireless earphones and earphone holders. Furthermore, the charging slot 106 can be integrated with the aforementioned trigger switch 73 into a single structure. For details, please refer to existing technologies.

[0067] In this embodiment, the main sump 103 and the sub-sump 104 can be vertically slotted or obliquely slotted. This embodiment takes oblique slotting as an example. Setting oblique slotting can reduce the thickness of the box 101, so as to facilitate the carrying and storage of the command box 100.

[0068] The laser module 50 is disposed on the top surface of the opened cover 102 and can emit a directional indicator laser upward after the cover 102 is opened; the box 101 and / or cover 102 of the command box 100 are also provided with an alarm horn 107 electrically connected to the command and control module 10; in this embodiment, the alarm horn 107 is disposed on the left and right sides of the box 101. When the fire spreads, when the commander presses the evacuation button 122, the alarm horn 107 can be triggered simultaneously to emit a piercing alarm to remind nearby personnel to evacuate.

[0069] The housing 101 is equipped with a housing battery 108, which is used to power the modules inside the command box 100. The housing battery 108 can also be connected to the mains power for charging.

[0070] The front side of the box 101 may also be provided with a handle 109 for easy access to the mobile command box 100.

[0071] like Figures 7 to 11 As shown, the sub-unit 202 in this embodiment includes a device body 81 and an intercom module 82, a temperature detection module 83, a control module 84, a gas detection module 85, a stationary detection module 86, an alarm module 87, an intercom battery 88, a location detection module 89, and a wireless module 90 integrated on the device body 81.

[0072] The control module 84 is electrically connected to the gas detection module 85, the stationary detection module 86, the alarm module 87, the position detection module 89, and the wireless module 90; the walkie-talkie battery 88 is used to power the various modules of the walkie-talkie 200.

[0073] The device body 81 of the sub-unit 202 in this embodiment is provided with a microphone speaker 821 of the intercom module 82 on its left or right side; the top surface of the device body 81 is provided with a temperature display panel 831 of the temperature detection module 83; the front of the device body 81 is provided with a gas detection probe 851 of the gas detection module 85 and an information display window 852, the information display window 852 being used to display the concentration of the detected gas; the stationary detection module 86 includes an acceleration sensor 861, the acceleration sensor 861 being used to sense the speed of the device body 81; the alarm module 87 includes an alarm speaker 871 and several alarm indicator lights 872; the alarm speaker 871 is used to emit an audible alarm, and the alarm indicator lights 872 are used to emit a visual alarm.

[0074] Therefore, the gas detection probes 851 of the gas detection module 85 are located on the front of the main body 81 of the device, which can detect the concentration of various gases in the environment in a timely manner. Once a gas concentration is detected to be too high, a signal can be transmitted to the control module 84 in a timely manner. The control module 84 then triggers the alarm speaker 871 of the alarm module 87 to emit a first sound and the alarm indicator light 872 to emit a first flashing light. The volume of the first sound is just loud enough for firefighters to hear, so as to warn firefighters to evacuate in time, thereby improving the safety of fire rescue and preventing firefighters from being in danger. At the same time, the gas detection probes 851 and the microphone speaker 821 are placed separately to avoid the gas exhaled during communication affecting the detection accuracy of the gas detection probes 851.

[0075] The accelerometer 861 of the static detection module 86 is used to detect the speed of the main body 81 of the device, that is, to detect whether the firefighter is moving. When the accelerometer 861 continuously detects that the speed of the main body 81 of the device is zero for a certain period of time, it can be determined that the firefighter may be unconscious due to inhaling harmful gases or has fallen to the ground due to other accidents and is in a static state. At this time, the control module 84 triggers the alarm speaker 871 of the alarm module 87 to emit a second sound and the alarm indicator light 872 to emit a second flashing light based on the signal provided by the accelerometer 861. The volume of the second sound can be greater than that of the first sound, so as to prompt other firefighters to discover the fallen firefighter in time for timely rescue, thereby improving the safety of firefighters. The second flashing light can also be distinguished from the first flashing light by using different colors, flashing frequencies, or brightness, which can be set according to actual needs.

[0076] The second sound and the second flashing light can serve as the aforementioned audible and visual alarm.

[0077] In this embodiment, each module can adopt existing technology. The control module 84 can be designed with a single-chip microcomputer for simple programming to receive signals from the gas detection module 85 and the static detection module 86, and control the alarm module 87 to operate. This part can refer to existing technology. By reasonably arranging the corresponding module functions on each side of the main body 81 of the device, the uses of the walkie-talkie 200 can be greatly enriched, realizing functions such as intercom communication, temperature detection, gas detection, static detection, and sound and light alarms, which can effectively improve the safety of firefighters in fire rescue.

[0078] In this embodiment, there may be four gas detection probes 851, which detect gases including H2S (hydrogen sulfide), CO (carbon monoxide), O2 (oxygen), and Ex (combustible gases, such as methane, acetylene, biogas, oil gas, ethanol, etc.). The information display window 852 can show the concentration of each gas, facilitating observation and judgment by firefighters.

[0079] In this embodiment, alarm indicator lights 872 are provided at the four corners of the front of the main body 81 and at the top and bottom of the left and right sides. This ensures that the main sides of the main body 81 can emit light indicators, reducing the possibility of light being blocked.

[0080] In this embodiment, the stationary detection module 86 further includes two switch buttons 862. The two switch buttons 862 are respectively located on the left and right sides of the main body 81 of the device. When both switch buttons 862 are pressed simultaneously, they control whether the acceleration sensor 861 operates. Since firefighters inevitably collide with the outside environment during firefighting operations, the use of two separately positioned switch buttons 862 prevents accidental shutdown and ensures the continuous operation of the stationary detection module 86. This also ensures that the alarm module 87 can sound normally should a firefighter fall to the ground. In other words, both switch buttons 862 must be pressed simultaneously to activate and deactivate the stationary detection module 86, preventing the alarm module 87 from sounding when the walkie-talkie 200 is not in use.

[0081] In this embodiment, the alarm module 87 further includes a shut-off button 873; the shut-off button 873 is disposed on the top surface of the device body 81; the shut-off button 873 is electrically connected to the control module 84 and is used to shut off the alarm speaker 871 and the alarm indicator light 872. When a firefighter does not faint but remains stationary for an extended period, causing the alarm module 87 to sound an alarm, the alarm speaker 871 and the alarm indicator light 872 can be temporarily shut off by manually pressing the shut-off button 873.

[0082] In this embodiment, the alarm speaker 871 can be located on the back or left and right sides of the device body 81 to make full use of the space of the device body 81. In this embodiment, the alarm speaker 871 is located on the back and can be an independent power speaker to ensure sufficient alarm volume. Of course, the alarm speaker 871 and the microphone speaker 821 can also be integrated into one unit to share a single speaker.

[0083] In this embodiment, the wireless module 90 further includes a retractable antenna 91; the retractable antenna 91 is disposed on one side of the top surface of the device body 81. This facilitates information transmission of the walkie-talkie 200 and enhances the quality of walkie-talkie calls.

[0084] In this embodiment, the information display window 852 and the gas detection probe 851 on the front of the main body 81 of the device are arranged vertically; between the two, there is also a power button 853 and an operation button 854. The power button 853 is used to start the gas detection module 85 and light up the information display window 852, and the operation button 854 is used to control the interface switching of the information display window 852.

[0085] Furthermore, the power button 853 can be integrated with the two switch buttons 862 into one unit, and the static detection module 86 and the gas detection module 85 can be turned on simultaneously through the two switch buttons 862.

[0086] In this embodiment, the gas detection module 85 further includes a strobe light 855, which is disposed on the front of the device body 81 and connected to the control module 84. That is, when the gas detection module 85 detects that the corresponding gas concentration is too high, it can also trigger the strobe light 855 to light up, so as to improve the warning effect.

[0087] In the illustration of this embodiment, the switch button 862 and the off button 873 are shown as simple protruding button structures. However, in practice, the switch button 862 and the off button 873 can also be designed as structures hidden on the surface of the device body 81 to further reduce the possibility of accidental touch and improve the durability and service life of the buttons.
