Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting rescue command system. Background Art

[0002] In traditional firefighting and rescue systems, firefighters deployed to a fire scene for investigation, firefighting, and other operations can only communicate with the command center via police walkie-talkies. However, due to the complexities of a fire scene and the frequent occurrence of emergencies, firefighters may be unable to call the command center for help in a timely manner, missing the best opportunity for rescue. Furthermore, the command center is unable to obtain real-time and dynamic information about the firefighters' situation, hindering commanders from providing precise commands and limiting the effectiveness of the command system.

[0003] Therefore, Chinese patent CN2899322Y discloses a multi-point wireless distress call device for firefighters at fire scenes. When a firefighter carries a handset with him / her into a fire scene or accident scene to conduct disaster reconnaissance, fire fighting and rescue, and emergency relief, if he / she encounters a dangerous situation that threatens his / her personal safety, the handset will manually or automatically send out a continuous alarm sound signal, a positioning strobe light signal, and an alarm working status radio signal. The commander of the main unit can confirm that the firefighter is in distress based on the alarm working status radio signal received by the main unit and can immediately dispatch rescue personnel to provide assistance.

[0004] However, this device can only assist firefighters after they are in danger, not beforehand. Furthermore, the neutron and main units are separate, making storage and access difficult. Furthermore, the device cannot monitor the location of firefighters in real time. In some large industrial plants, with complex roads, firefighters could get lost and get into danger during an emergency evacuation, preventing them from reaching safety. Summary of the Invention

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] like Figures 1 to 11 As shown, a fire rescue command system of this embodiment includes a command box 100 and several intercoms 200; The intercom 200 includes a host 201 and multiple sub-machines 202 that can communicate with each other; the sub-machines 202 of this embodiment can realize firefighter stillness detection, ambient temperature detection, ambient gas concentration detection, firefighter position detection and sound and light alarms.

[0024] The host 201 can have the same structure as the slave 202, or it can only have an intercom function. Firefighters carry the slave 202 with them when entering a fire scene, while the host 201 is in a safe area and is carried by the commander to facilitate communication with teammates attacking the fire scene.

[0025] The command box 100 includes a box body 101 and a cover body 102, and is provided 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 sub-machine 202 through the wireless module 60, and is used to receive data detected by the sub-machine 202 and display it.

[0026] The top surface of the box body 101 is concavely provided with a main storage slot 103 and several sub-slots 104, the main storage slot 103 is used for accommodating the main unit 201 in a removable manner, and the sub-slots 104 are used for accommodating each sub-machine 202 in a removable manner; the cover body 102 is hinged to one side of the top surface of the box body 101 in an openable and closable manner; by providing the main storage slot 103 and the sub-slots 104, each intercom 200 can be conveniently stored and preserved, and the cover body 102 can be covered on the box body 101 to form a portable command box 100. When a fire hazard occurs, the command box 100 and the multiple intercoms 200 inside can be quickly brought to the scene without missing the intercoms 200; and after opening the cover body 102, the firefighters can accurately and quickly take out each sub-machine 202 for wearing, which is convenient and fast to use, can save time in wearing equipment, and is convenient for efficient firefighting.

[0027] The display module 20 is a display screen 21 mounted on the cover 102. The information module 30 is used to record the ambient temperature and gas concentration detected by each slave unit 202. The map module 40 is used to store map data. The map data in the map module 40 can be pre-stored based on the city where the firefighter is located. For example, map data for all key firefighting units in the city can be pre-entered and corresponding firefighting plans can be set up for easy subsequent use. Of course, this map data can also be integrated with the map and positioning functions of existing navigation software in real time.

[0028] The left side of the display screen 21 of the display module 20 can display the data recorded by the information module 30, and the right side displays the rescue site map 41 while marking the position of each sub-machine 202 in the rescue site map 41; each sub-machine 202 represents a firefighter teammate, and by displaying the ambient temperature and ambient gas concentration of each firefighter's environment on the display screen 21, the commander can promptly determine whether each firefighter is in a dangerous environment, for example, 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 make targeted and quick reminders through the host 201, call the corresponding firefighters to retreat, and prevent the firefighters from falling into danger, which can improve the safety of the firefighting and rescue process and protect the lives of firefighters.

[0029] Moreover, the display screen 21 can also display the rescue scene map 41 in real time, and in conjunction with the firefighter positions detected by the sub-unit 202, it is convenient for the commander to observe the positions of each firefighter in the rescue scene map 41, facilitate overall command, and can command the firefighters to besiege the fire scene or guide the firefighters to retreat routes, etc.

[0030] The laser module 50 is used to emit a directional laser upward. Thus, during an emergency, firefighters can follow the direction of the directional laser to avoid getting lost. Typically, the laser can illuminate an altitude of up to 10 kilometers.

[0031] In summary, by adopting this fire rescue command system, when entering the scene for rescue and fire fighting, each firefighter can quickly take out the sub-machine 202 from the box 101 and wear it with them, while the command box 100 and the main machine 201 can be placed in a safe and open area, and the commander can command in a safe area.

[0032] The firefighter's sub-machine 202 can not only communicate with the host machine 201 in real time, but also detect the temperature and gas concentration in the fire scene. Once the temperature or gas is abnormal, the sub-machine 202 will be triggered to emit an audible and visual alarm to remind the firefighters on the scene to retreat actively. Moreover, the sub-machine 202 can also transmit the data detected in the fire scene to the command box 100. The commander can predict in advance whether there are risks such as combustion and explosion based on the ambient temperature and ambient gas concentration of the area where each firefighter is located. That is, the commander can notify the firefighters to take precautions in advance.

[0033] The firefighter's handset 202 can also detect the firefighter's stationary state, that is, whether the firefighter is moving. If the firefighter remains stationary for a certain period of time, it can be determined that the firefighter has fainted due to inhaling harmful gases or collapsed due to other accidents. At this time, the handset 202 will emit an audible and visual alarm and simultaneously transmit a rescue signal to the command box 100, allowing the commander to promptly dispatch search and rescue personnel to the scene. The audible and visual alarm of the handset 202 can also prompt other firefighters or rescue personnel to promptly discover the fallen firefighter, making it easier to find the fallen firefighter in a fire scene with dense smoke and complex conditions, thereby improving rescue efficiency and enhancing the safety of firefighters.

[0034] In this embodiment, the command and control module 10 includes a control panel 11 and a plurality of control buttons 12 provided on the top surface of the housing 101. The control buttons 12 include a single-person retreat button 121, a full-person retreat button 122, and a laser control button 123. Each control button 12 is electrically connected to the control panel 11, which is in turn electrically connected to the modules within the command box 100. Each single-person retreat button 121 corresponds to a corresponding slave unit 202 and is used to independently control whether the corresponding slave unit 202 plays a retreat alarm. The full-person retreat button 122 is used to control whether all slave units 202 play a retreat alarm. When the commander observes changes in the fire scene environment, he or she can press the single-person retreat button 121 as needed to cause the corresponding slave unit 202 to issue a retreat alarm, prompting firefighters in the corresponding area to retreat. When the fire scene collapses or spreads, he or she can also press the full-person retreat button 122 to remind all firefighters to retreat urgently.

[0035] Compared to calling for evacuation through an intercom, by setting a single-person retreat button 121 and a full-person retreat button 122 on the command box 100 and enabling the slave 202 to issue a dedicated retreat alarm, firefighters can be reminded to evacuate more quickly and accurately.

[0036] The laser control button 123 is used to control whether the laser module 50 emits laser or not. The commander presses the laser control button 123 as needed to turn on the laser.

[0037] In this embodiment, the top surface of the box 101 is recessed with a plurality of internal attack grouping areas 105 arranged side by side in front and back. In this embodiment, there are three internal attack grouping areas 105, and each internal attack grouping area 105 is provided with three sub-slots 104 spaced apart on the left and right. That is, there are nine intercoms 200 and sub-units 202 in the box 101, which can be numbered 1-9 and can be used by three internal attack teams, each of which includes three teammates; a single retreat button 121 is provided on the front side of each sub-slot 104; each teammate can bind his identity with the sub-unit 202 in each sub-slot 104 in advance, and the information column of the corresponding sub-unit 202 displayed on the display screen 21 can be attached with the corresponding teammate's name.

[0038] The command and control module 10 also includes a plurality of group retreat buttons 124 corresponding to the number of internal attack grouping areas 105. Each group retreat button 124 is located adjacent to each internal attack grouping area 105 and is used to trigger each slave 202 within the corresponding internal attack grouping area 105 to play a retreat alarm. Thus, by providing additional group retreat buttons 124, all teammates in the corresponding group can evacuate simultaneously.

[0039] In this embodiment, a face detection module 70 may also be provided in the command box 100; the face detection module 70 includes a face recording module 71, a camera 72 provided on the cover 102 and a trigger switch 73 provided in each sub-slot 104, and the face recording module 71 is electrically connected to the command 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 taken out, and the face recording module 71 controls the camera 72 to detect the face and record it.

[0040] Therefore, the sub-machine 202 does not need to be bound to the identity of a firefighter in advance. When a firefighter uses the sub-machine 202, the trigger switch 73 will be automatically triggered, and then the corresponding facial image will be recorded through the camera 72 at the same time, so that the face of the firefighter can be bound to the corresponding sub-machine 202 among No. 1-9. The corresponding facial image can also be sent to the command and control module 10 through the face recording module 71, and transmitted and displayed on the display screen 21 through the command and control module 10. The facial image can be associated with the corresponding sub-machine 202, which is convenient for the commander to observe, judge and call.

[0041] The trigger switch 73 adopts the existing technology, which is schematically shown in the figure. The trigger switch 73 can be an elastic contact structure such as a spring pin or a spring piece. When the sub-machine 202 is taken out of the sub-housing 104, the trigger switch 73 can be automatically triggered, which is more convenient to use.

[0042] Furthermore, the main container 103 and the sub-compartment 104 can be provided with a container charging device 106, and the host 201 and the sub-machine 202 are both provided with a walkie-talkie charging device 203. The container charging device 106 and the walkie-talkie charging device 203 cooperate to charge the accommodated host 201 and sub-machine 202.

[0043] The charging slot device 106 and the intercom charging device 203 can be used to charge via an interface structure such as Type-C / USB, a wireless charging module, or a magnetic charging structure similar to that between wireless headphones and a headphone jack. Furthermore, the charging slot device 106 and the trigger switch 73 can be integrated into a single structure. For details, please refer to the prior art.

[0044] In this embodiment, the main container slot 103 and the sub-container slot 104 can be vertical slots or oblique slots. This embodiment takes oblique slots as an example. Setting oblique slots can reduce the thickness of the box body 101 to facilitate carrying and storage of the command box 100.

[0045] The laser module 50 is arranged on the top surface of the cover 102 after it is opened, and can emit a direction-indicating laser upward after the cover 102 is opened; the box 101 and / or the cover 102 of the command box 100 are also provided with an alarm speaker 107 electrically connected to the command and control module 10; the alarm speaker 107 of this embodiment is arranged on the left and right sides of the box 101. When the fire spreads, when the commander presses the retreat button 122, the alarm speaker 107 can also be triggered synchronously to emit a shrill alarm to remind all nearby personnel to evacuate.

[0046] A box battery 108 is provided in the box 101 , and the box battery 108 is used to power the modules in the command box 100 . The box battery 108 can also be connected to the mains for charging.

[0047] The front side of the box 101 may also be provided with a box handle 109 to facilitate taking the mobile command box 100.

[0048] like Figures 7 to 11 As shown, the sub-machine 202 of 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 stillness detection module 86, an alarm module 87, an intercom battery 88, a position detection module 89 and a wireless module 90 integrated on the device body 81.

[0049] 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 intercom battery 88 is used to power each module of the intercom 200 .

[0050] In this embodiment, the left or right side of the device body 81 of the sub-machine 202 is provided with a microphone speaker 821 of the intercom module 82; the top surface of the device body 81 is provided with a temperature display panel 831 of the temperature detection module 83; the front surface of the device body 81 is provided with a gas detection probe 851 and an information display window 852 of the gas detection module 85, and the information display window 852 is used to display the concentration of the detected gas; the stationary detection module 86 includes an acceleration sensor 861, and the acceleration sensor 861 is 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 issue a sound alarm, and the alarm indicator lights 872 are used to issue a light alarm.

[0051] Thus, the gas detection probes 851 of the gas detection module 85 are disposed on the front of the device body 81 and can promptly detect the concentrations of various gases in the environment. Once an excessively high concentration of a particular gas is detected, a signal can be promptly transmitted to the control module 84. 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 sufficient for firefighters to hear, thereby alerting them to evacuate in a timely manner, thereby improving the safety of firefighting and rescue operations and preventing them from falling into danger. Furthermore, the gas detection probes 851 and the microphone speaker 821 are placed separately to prevent exhaled gas from affecting the detection accuracy of the gas detection probes 851 during intercoms.

[0052] The accelerometer 861 of the stationary detection module 86 is used to detect the speed of the device body 81, that is, to detect whether the firefighter is in motion. When the accelerometer 861 continuously detects zero speed of the sensing device body 81 for a certain period of time, it can be determined that the firefighter is stationary, perhaps fainting from inhaling harmful gases or collapsing due to other accidents. 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 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 the volume of the first sound, so that it can cooperate with the light to prompt other firefighters to promptly discover the fallen firefighter, facilitate timely rescue, and thus improve the safety of the firefighter. The second flashing light can also be distinguished from the first flashing light, using different colors, flashing frequencies, or brightness, etc., which can be set according to actual needs.

[0053] The second sound and the second flashing light may be the aforementioned sound and light alarm.

[0054] In this embodiment, each module can adopt existing technology. The control module 84 can be simply programmed with a single-chip microcomputer to receive signals from the gas detection module 85 and the stillness detection module 86, and control the operation of the alarm module 87. This part can refer to the existing technology. By reasonably arranging the corresponding module functions on each side of the device body 81, the use of the walkie-talkie 200 can be greatly enriched, and functions such as intercom calls, temperature detection, gas detection, stillness detection, and sound and light alarms can be realized, which can effectively improve the firefighting and rescue safety of firefighters.

[0055] In this embodiment, there may be four gas detection probes 851, detecting gases including H2S (hydrogen sulfide), CO (carbon monoxide), O2 (oxygen), and Ex (combustible gases such as methane, acetylene, biogas, oil gas, ethanol, etc.). Furthermore, the information display window 852 can display the concentration of each gas, facilitating observation and judgment by firefighters.

[0056] In this embodiment, the alarm indicator lights 872 are provided at the four corners of the front face and the upper and lower ends of the left and right sides of the device body 81. This ensures that the main sides of the device body 81 can emit light indications to reduce the possibility of light being blocked.

[0057] In this embodiment, the inactivity detection module 86 also includes two switch buttons 862, located on the left and right sides of the device body 81, respectively. When both switch buttons 862 are pressed simultaneously, they control the operation of the acceleration sensor 861. Since firefighters inevitably collide with the outside world during firefighting, the provision of two separate switch buttons 862 prevents accidental activation of the inactivity detection module 86. This prevents accidental activation of one switch button 862, which could cause the inactivity detection module 86 to cease operation. This ensures the continued operation of the inactivity detection module 86 and ensures that the alarm module 87 can properly sound an alarm in the event that a firefighter collapses. Specifically, both switch buttons 862 must be pressed simultaneously to activate the inactivity detection module 86 during operation, and both switch buttons 862 must be pressed simultaneously to deactivate the inactivity detection module 86 during deactivation. This prevents the alarm module 87 from sounding an alarm even when the intercom 200 is not in use.

[0058] In this embodiment, the alarm module 87 further includes an off button 873 disposed on the top surface of the device body 81. The off button 873 is electrically connected to the control module 84 and is used to silence the alarm speaker 871 and the alarm indicator light 872. If the firefighter has not fainted but has been immobile for an extended period, causing the alarm module 87 to sound an alarm, the off button 873 can be manually pressed to temporarily silence the alarm speaker 871 and the alarm indicator light 872.

[0059] In this embodiment, the alarm speaker 871 can be located on the back or on one of the left or right sides of the device body 81 to fully utilize the space of the device body 81. In this embodiment, the alarm speaker 871 is located on the back and can be a speaker with independent power to ensure sufficient alarm volume. Of course, the alarm speaker 871 can also be integrated with the microphone speaker 821 to share a single speaker.

[0060] In this embodiment, the wireless module 90 further includes a telescopic antenna 91, which is disposed on one side of the top surface of the device body 81 to facilitate information transmission of the intercom 200 and enhance intercom call quality.

[0061] In this embodiment, the information display window 852 and the gas detection probe 851 are distributed up and down on the front of the device body 81; a power button 853 and an operation button 854 are provided between the two. 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.

[0062] Furthermore, the power button 853 and the two switch buttons 862 may be integrated into one, and the stillness detection module 86 and the gas detection module 85 may be turned on synchronously through the two switch buttons 862 .

[0063] 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 of this embodiment detects that the corresponding gas concentration is too high, it can also trigger the strobe light 855 to light up, thereby enhancing the warning effect.

[0064] In the diagram of this embodiment, the switch button 862 and the off button 873 are shown as simple protruding button structures. In practice, the switch button 862 and the off button 873 can also be designed as a structure hidden on the surface of the device body 81 to further reduce the possibility of accidental touches and improve the durability and service life of the buttons.
