Description

Technical Field:

[0001] The present invention relates to the technical field of fire extinguishing, and in particular to a carbon dioxide fire extinguishing system applied to vehicle intelligence and its ship. Background Art:

[0002] Carbon dioxide is widely used on ships. After being liquefied under high pressure, carbon dioxide is canned and stored. When it is sprayed, its volume expands sharply and absorbs a large amount of heat, which can reduce the temperature at the fire site. At the same time, it dilutes the oxygen concentration in the protected space to achieve the effect of extinguishing fire by asphyxiation. Carbon dioxide is an inert gas, cheap in price, does not pollute the fire site environment during fire extinguishing, and quickly dissipates after fire extinguishing without leaving traces.

[0003] It should be noted that carbon dioxide has an asphyxiating effect on the human body, and the system can only be used in unmanned places. When installed and used in places where people often work, appropriate protective measures should be taken to ensure the safety of personnel.

[0004] The carbon dioxide automatic fire extinguishing system can be divided into a total flooding fire extinguishing system mode and a local application fire extinguishing system mode according to its designed application form. The total flooding fire extinguishing system mode means that within a certain period of time, a certain concentration of fire extinguishing agent is sprayed into the protected area and evenly fills the entire protected area. The total flooding fire extinguishing system mode should be used for fire protection of enclosed protected areas where the fire generation location cannot be predicted in advance. The local application fire extinguishing system mode directly sprays the fire extinguishing agent onto the protected object at the designed spraying intensity and lasts for a certain period of time. The local application fire extinguishing system mode should be used for fire protection of local non-enclosed places where the fire generation location can be predicted in advance. The combined distribution system refers to a protection form in which a set of carbon dioxide automatic fire extinguishing systems protects multiple protected areas. If the number of protected areas or protected objects is 5 or more, standby bottle groups should be equipped, and the fire extinguishing agent dosage should not be less than the designed dosage.

[0005] The carbon dioxide fire extinguishing system is divided into a high-pressure carbon dioxide fire extinguishing system and a low-pressure carbon dioxide fire extinguishing system. The high-pressure carbon dioxide system sets several gas cylinder groups, and several high-pressure gas cylinders are set in each gas cylinder group. The low-pressure carbon dioxide system is set as a larger liquid tank.

[0037] Specific embodiments of the present application are hereinafter described with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present application and can be implemented in various ways. Well - known and / or repetitive functions and structures are not described in detail to clarify the true intention based on the user's historical operations and to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but are merely used as a basis for the claims and a representative basis for teaching those skilled in the art to use the present application in substantially any suitable detailed structure in a variety of ways.

[0038] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", all of which may refer to one or more of the same or different embodiments according to the present application.

[0039] According to the characteristics and extinguishing methods of carbon dioxide fire extinguishing agent, the carbon dioxide fire extinguishing system can be used to extinguish: ① gas fires that can cut off the gas source before extinguishing; ② liquid fires or fires of meltable solids such as paraffin and asphalt; ③ fires on the surface of solids and some deep - seated solid fires such as cotton, wool, fabrics, paper, etc.; ④ electrical fires, such as those of transformers, oil switches, electronic equipment, etc.

[0040] The carbon dioxide automatic fire extinguishing system consists of main equipment such as a gas fire alarm control system, an audible and visual alarm device, a CO2 control box, emergency start and stop buttons, fire extinguishing agent storage cylinders, container valves, high-pressure hoses, selector valves, check valves, gas path control valves, pressure switches, nozzles, starting cylinders, pipelines, etc. It can form various forms such as a unit independent system or a combined distribution system to implement fire protection for a single area or multiple areas. The CO2 system is a gas fire extinguishing system. The principle is that CO2 is heavier than air in weight and does not support combustion. After the oxygen in the cabin burns out and CO2 is released, it fills the vehicle cabin, and since there is no O2 to support combustion, combustion cannot occur. The CO2 system is also a very dangerous system, and when it is used and released, personnel must evacuate safely. When a fire occurs, in the fire alarm system, personnel must wait until all the personnel in the vehicle cabin have safely evacuated before manually starting the CO2 system control box to extinguish the fire. When extinguishing the fire, the audible and visual alarm is activated to remind personnel to evacuate safely again. The spread of a fire is very rapid, which is relatively unfavorable for extinguishing the fire. It is very likely that a small fire will quickly expand, resulting in the inability to achieve the fire extinguishing effect even when the CO2 system is started, and the loss caused by the fire will be even greater. Therefore, it is necessary to optimize the original system design to improve the fire extinguishing effect.

[0041] Figure 1 Schematic diagram of a thermal detection image in an embodiment of the present invention; Figure 2 Schematic diagram of the system architecture in another embodiment of the present invention; Figure 3 Schematic diagram of the layout of the gas cylinders in the fire extinguisher gas source compartment in another embodiment of the present invention. As Figures 1 to 3 shown, in one embodiment, the present invention provides a carbon dioxide fire extinguishing system applied to a ship cabin. The carbon dioxide fire extinguishing system applied to the ship cabin includes:

[0042] A thermal analysis monitoring system for sending the monitoring results to the carbon dioxide fire extinguishing device, determining whether to extinguish the fire according to the detection results, and closing the ventilation system if fire extinguishing is required;

[0043] An AI smoke and fire recognition system for judging the fire extinguishing control mode of the carbon dioxide fire extinguishing device according to the smoke and fire images of the thermal analysis monitoring system. Among them, the AI smoke and fire recognition system has a smoke and fire recognition model, and the smoke and fire recognition model is trained with real-time detection data for each frame of raw data.

[0044] In this embodiment, a specific implementation manner of a carbon dioxide fire extinguishing system applied to a ship's cabin is provided. It should be noted that in the prior art, point-to-point temperature measurement is performed through smoke sensors or thermal energy sensors, etc., and then fire extinguishing is carried out through spraying and other methods. However, for the cabins inside a ship, especially for ships similar to cargo ships or even roll-on / roll-off ships carrying vehicles, due to the relatively large area, this sensor method can no longer meet the needs of this scenario. Therefore, a thermal analysis detection system is introduced to analyze the thermal image. The specific analysis method is as follows:

[0045] Obtain the thermal image of the real-time predetermined area;

[0046] According to the thermal changes of the thermal image under different working conditions, extinguish the fire by different carbon dioxide fire extinguishing methods.

[0047] Furthermore, when the temperature in a part of the predetermined area exceeds the predetermined threshold, extinguish the fire in that part of the area.

[0048] If the temperature in the predetermined area exceeding the predetermined range of area exceeds the predetermined threshold, extinguish the fire in the entire area.

[0049] In addition, according to the smoke and fire image, the trend of the fire can be judged, and carbon dioxide fire extinguishing is carried out on the predetermined area according to the trend of the fire.

[0050] Because the gas source of carbon dioxide is used once in the application environment of the ship. When it is used again, it needs to be restarted, refilled and repaired. Therefore, the gas source resources are limited. Moreover, the cabins inside the ship, especially the cargo ship, are relatively large. So if comprehensive area fire extinguishing is simply used, the gas source may be quickly consumed. In order to further extinguish the fire efficiently, since the flow direction of the temperature can reflect the trend of the fire, fire extinguishing can be carried out according to the flow direction of the temperature, and the flow rate of carbon dioxide can be controlled targeted to carry out regional fire extinguishing.

[0051] In one embodiment, the thermal analysis monitoring system uses infrared imaging technology for monitoring.

[0052] In one embodiment, thermal imaging superposition is realized through dual-light fusion technology.

[0053] In one embodiment, the carbon dioxide fire extinguishing system applied to vehicle intelligence further includes a fire control station, and the fire control station is arranged in the superstructure area of the ship.

[0054] In one embodiment, the carbon dioxide fire extinguishing system applied to vehicle intelligence further includes an audible and visual alarm, and the audible and visual alarm realizes the alarm function according to the fire extinguishing situation.

[0055] In one embodiment, the carbon dioxide fire extinguishing device includes multiple groups of carbon dioxide cylinder groups, and the carbon dioxide cylinder groups are arranged in the ship's cabin through pipelines.

[0056] In one embodiment, the carbon dioxide fire extinguishing device further includes a carbon dioxide control box, and the carbon dioxide control box includes the fire control station, the alarm relay box, and a control device;

[0057] The control device is electrically connected to the alarm relay box;

[0058] The alarm relay box is electrically connected to the audible and visual alarm.

[0059] In one embodiment, the carbon dioxide fire extinguishing system applied to vehicle intelligentization further includes a spraying device for spraying and cooling in the cabin.

[0060] In one embodiment, the cabin has a cabin door.

[0061] In one embodiment, the present invention further provides a ship with a carbon dioxide fire extinguishing system applied to vehicle intelligentization. The ship includes the carbon dioxide fire extinguishing system applied to the ship's cabin as described above, and the system is arranged in the cabin.

[0062] Design solution: To achieve the above functions, the following problems need to be solved: 1) Intelligent fire monitoring and rapid response When a car catches fire, the fire is confined inside the car's outer shell, and the temperature cannot be quickly transmitted to the outside and detected by the temperature fire alarm probe. This causes the temperature fire alarm probe to not give an alarm in the shortest time, delaying the fire extinguishing time. 2) Fire process monitoring and fire control In view of the characteristic that a car fire may reignite, monitor the fire process, analyze the fire status in real time, and avoid the occurrence of secondary fires. It can also give feedback on the fire extinguishing effect, monitor the status of the fire area, and judge whether the fire area allows personnel to enter. 3) Safe evacuation of personnel Ensure the rapid and safe evacuation of personnel, and at the same time shorten the preparation time. 4) Intelligent auxiliary system Take relevant measures and equipment to reduce the possibility of fire, make an intelligent auxiliary judgment on the fire, assist the captain in fire extinguishing operations, or make decisions such as escaping or abandoning the ship. Countermeasures: 1) Study the characteristics of the initial stage of a car fire, use infrared thermal imaging technology, and through intelligent data analysis, the aim is to detect the occurrence of a fire faster than the external temperature fire alarm probe at the initial stage of the fire and make a rapid response, so as to be able to carry out fire extinguishing operations using the golden fire extinguishing time at the initial stage of the fire. Design a CCTV system with thermal imaging monitoring to monitor the temperature change of the garage deck. When the camera detects abnormal temperature, trigger the alarm of the CCTV workstation. Timely eliminate the cars that may catch fire. Through the temperature measurement model, strict calibration and standardized inspection process, effectively improve the accuracy of temperature measurement. Make the temperature difference fluctuation of temperature measurement small and the stability better; The dual-light fusion technology, superimposed in the thermal imaging, can show the light details, which is convenient for judgment. Support flexible multi-rule layout of points, lines, and frames to meet the temperature measurement needs of key areas and special points.

[0063] Through comprehensive analysis, when it is determined that fire extinguishing is required in a certain area, the CCTV will transmit the result to the CO2 system via signal. The CO2 system will activate the audible and visual alarm, and at the same time, shut down the ventilation system to isolate the air. When the personnel have safely evacuated, the CO2 system will start to extinguish the fire. 2) Analyze the situation of smoke and fire in the video through a set of AI algorithms. Smoke and fire recognition algorithm based on the deep integration of deep learning and AI: Learn from the cases of global vehicle combustion, and analyze samples in different climates and environments comprehensively, so as to obtain a high-precision smoke and fire recognition algorithm that is most similar to the current ship. Use raw data to detect each frame in real time and perform adaptive fast dynamic detection to achieve faster detection and alarm of smoke and fire. Through thermal imaging technology and AI monitoring, judge the situation after fire extinguishing, determine whether the fire extinguishing effect has been achieved, prevent misoperation and re-ignition after combustion, and also avoid the danger caused by personnel staying in it. 3) Personnel safety evacuation system The CO2 system for fire extinguishing is very dangerous because this gas can cause asphyxiation to people and it is a one-time dangerous fire extinguishing system. Therefore, the CO2 system must be activated only after the personnel have safely evacuated. The CO2 room and the fire control station are the operating rooms of the CO2 system, but when there is a fire, the personnel are relatively scattered. If the CO2 system is activated after all personnel have arrived at the report, the opportunity for CO2 fire extinguishing will be delayed... 5 Generally, there are more personnel in the engine room, superstructure, and cab. The engine room is the main working area, and the superstructure is the rest area. Set the fire control station in the superstructure area to solve the problem of personnel arrival in the superstructure area. There are usually people staying on duty in the centralized control room of the engine room and the superstructure cab to operate the ship's navigation and they cannot evacuate. Therefore, a collection terminal is set up in each of the centralized control room and the cab. This terminal is a face recognition intelligent system to avoid misjudgment and omission of personnel. When there is a fire, there will be an audible and visual alarm, and the personnel will quickly evacuate the burning deck and rush to the centralized control room, cab, CO2 room, and fire control station. According to the principle of proximity, as long as the personnel escape to any of the above areas, data collection can be achieved. After all the personnel have arrived, the captain will activate the CO2 fire extinguishing system to extinguish the fire. This saves time and also takes into account the personal safety issue. The design is reasonable and effective, improving the convenience and intelligence of the CO2 system. 4) Auxiliary system Set up an auxiliary system. In addition to the CO2 fire extinguishing system, other equipment and measures are also set up for comprehensive functions. Auxiliary configuration system: 1) There should be no less than 2 sets of handheld foam fire extinguishers in the vehicle loading cabin. 2) Fresh water pipes are configured in the open loading area, and automatic sprinkler cooling is started under high-temperature climate conditions. Fire extinguishing reminder system: When it is found that the CO2 system in the current fire area fails to achieve the expected fire extinguishing effect continuously, it will automatically alarm - for fire extinguishing and remedial measures, reminding the captain to make a judgment and perform corresponding operations. Escape reminder system: This system can guide the safe escape route and direct the personnel in the fire area to escape safely nearby. It can also comprehensively analyze and judge that the fire is out of control, or the fire extinguishing in the key area is out of control, which may lead to risks such as explosion, and automatically give an audible and visual alarm to abandon the ship, switch the escape equipment, and guide the crew to perform escape / abandon ship operations according to the instructions.In summary, the intelligent CO2 system is designed for prevention, startup, re-ignition monitoring, as well as fire extinguishing effect remedy and escape reminder of the auxiliary system. Its functions are relatively comprehensive and powerful. In addition to being automated, the functions can also be manually switched to achieve comprehensive human-machine judgment and use.

[0064] Beneficial effects:

[0065] Describe the advantages of the invention over the prior art, and specifically analyze the problems solved by the invention in the prior art, the defects overcome in the prior art, and the reasons for the advantages.

[0066] This method makes up for the lack of prevention function, remedy function, re-ignition monitoring function, safe evacuation function, and escape judgment function in the traditional system. This method takes into account aspects such as design, prevention, monitoring, remedy, escape / abandon ship, etc. It uses new technologies such as thermal imaging and AI integration to maximize the protection of vehicle safety, property, and personal safety. Its functions are relatively comprehensive and powerful, realizing the all-round intelligent design of the CO2 fire extinguishing system.
