Description

Technical Field

[0001] The present invention belongs to a design method for a comprehensive fire management system, especially applied to the design field of a comprehensive fire management system for a smart city. Background Art

[0002] Currently, the causes of fires in cities mainly include electrical fires, fires caused by combustibles in production and life, and fires caused by the natural environment. The fire areas mainly occur in residential areas, factory areas, cultivated land, forest areas and other regions. However, the design of a comprehensive fire management system for a smart city has not yet taken shape. Fire alarm systems are designed for only one type of fire cause. Each electrical fire monitoring system, production and life combustible fire monitoring system, and natural environment fire monitoring system are independent of each other, resulting in a large number of independent fire systems in the smart city, lacking linkage and unified management.

[0003] Currently, the focus of fire prevention is mainly on the post-treatment of fires, with insufficient depth in pre-event prevention. The processing procedures such as discovering a fire, reporting an alarm, issuing a fire extinguishing order, and the firemen extinguishing the fire are carried out serially under manual command, resulting in low fire prevention efficiency and lack of comprehensive intelligent disposal.

[0004] Neither the firemen nor the personnel in the command center know the distribution of people, property, and dangerous goods at the fire scene and its surrounding areas. They still need to find people familiar with the area on-site to inquire after arriving at the scene, and some even need to look for relevant information such as building materials to make a fire extinguishing plan, wasting valuable fire-fighting time. Without being able to quickly and comprehensively understand all the information at the scene, the optimal fire disposal plan cannot be made in the first place.

[0005] Currently, there is no overall management and research specifically for large-area monitoring of the entire urban area, multiple types of targets, and prevention of multiple fire causes. However, from the perspective of urban fire safety, it is necessary to consider comprehensively and prevent and control comprehensively.

[0006] Currently, the fire disposal system lacks monitoring and early warning of the people around the fire and information collection work, delaying the critical period of fire disposal and causing unnecessary economic losses and casualties.

[0007] Currently, the main fire alarm method relies on telephone alarms. The alarm method is single, the information is not clear, and it needs to be confirmed by querying the background, delaying the critical period of fire situation disposal, and unable to timely warn the people around, increasing the risk of casualties.

[0008] Currently, the fire brigade only dispatches after receiving an alarm and needs to communicate with the relevant person in charge after arriving at the destination to understand the fire situation and the surrounding conditions. There is a problem that the fire brigade cannot timely obtain the information of the fire scene and its surrounding areas in the process.

[0009] Currently, in the prevention and control of electrical fires, the main equipment is electrical monitoring devices, which are mainly responsible for monitoring, alarming, and controlling functions. After a fire event occurs at the trigger threshold, there is no analysis and prediction of electrical parameters, and it is impossible to achieve the effect of alarming and handling before the fire, lacking the prevention, early warning, and comprehensive management of electrical fires.

[0010] Currently, the monitoring of combustible fires in production and life mainly relies on indoor monitors, with insufficient subdivision of usage scenarios, resulting in insufficient alarm sensitivity, delaying the alarm time, or being too sensitive, leading to false alarms and easily causing human damage.

[0011] Currently, the monitoring of natural environment fires in urban areas mainly relies on high-point fire monitoring, mainly for post-event monitoring and alarming, lacking the recognition of characteristic scenarios in the monitoring area and the assessment of risk levels at different times, and unable to accurately determine the location, scope, and trend of the fire.

[0012] Currently, the command and management platform focuses on the way of reporting level by level, resulting in information loss and untimely update. Information asymmetry is likely to cause misjudgment and misoperation, thus missing the critical period for fire extinguishing.

[0013] Currently, the command and management platform lacks the assessment of each link in the operation of the system and the overall operation effect. There are some links with poor effects, which may affect the fire prevention efficiency and delay the fire prevention time.

[0014] Currently, the command and management platform is a static implementation of the current design concept, lacking the auxiliary decision-making ability of self-improvement, self-correction, and self-evolution, and lacking the vitality of continuous application and adjustment. Summary of the Invention

[0016] To solve the above-mentioned existing technical problems in the fire prevention of smart cities, the purpose of the present invention is:

[0017] Design a comprehensive fire management system for smart cities to improve the efficiency of fire prevention and disposal in the management area of smart cities.

[0018] To achieve the above-mentioned invention purpose, the following technical solutions are adopted:

[0019] The comprehensive fire management system for smart cities mainly includes a fire monitoring terminal 1, a transmission network 4, a monitoring and management command platform 2, and a fire handling unit 3.

[0020] The fire monitoring terminal 1 mainly includes an indoor monitoring sensor 11, a power monitoring controller 12, a high-point fire monitor 13, and a public monitoring unit 14.

[0021] The indoor monitoring sensor 11 mainly includes special substance sensors such as a smoke sensor with customized sensitivity, a temperature sensor with customized sensitivity, and a combustible gas sensor.

[0022] Customized sensitivity smoke sensors are mainly deployed in indoor enclosed environments and alarm according to the concentration of smoke during a fire. However, in different usage scenarios, the concentration of smoke is closely related to the fire situation. In a smoke-free area, as long as there is smoke, there is a possibility of a fire. The smoke detector is set to the smoke-free level and will alarm immediately when smoke is detected, enabling the quick discovery of a fire. In high-risk areas with a high fire risk, the smoke monitoring sensitivity is appropriately increased. In a family bedroom, smoking may occur, and the smoke concentration generated during smoking does not trigger an alarm. In a family kitchen and a commercial kitchen, there is often smoke, and the alarm value needs to be set according to the daily smoke situation. In public areas of shopping malls, factory areas, and special places, smoke sensors with different sensitivities need to be selected according to different actual usage situations. The smoke detector is established as different scenario models, and different safety alarm parameter thresholds are set. When the alarm threshold is reached, the local alarm of the speaker is triggered, shortening the time for fire monitoring. When the local alarm is triggered, the fire information is simultaneously sent to the monitoring and management command platform and all levels of fire response units through the transmission network.

[0023] Customized sensitivity temperature sensors are mainly used in certain scenarios where substances are not easily ignited to produce smoke, but the temperature has risen to a very high level, presenting a high probability of fire hazards. Since the smoke detector cannot alarm in time, the temperature sensor needs to set a safe temperature monitoring threshold to give an early warning before a fire occurs, compensating for the risk of failure in fire smoke monitoring.

[0024] Combustible gas sensors are selected according to the characteristics of the gas used. In production and daily life, when the gas leaks to a certain extent, there is no smoke and no temperature increase, but there is a high fire hazard. Smoke monitoring and temperature monitoring can only alarm after a fire occurs, failing to achieve early warning and prevent fires. Selecting gas sensors can give an early warning before a fire occurs in a timely manner, avoiding the fire risk.

[0025] Special substance sensors mainly give an early warning based on the characteristic changes of the substance. When a fire is about to occur to a special substance, the change in characteristic parameters is faster than the change in temperature parameters and smoke sensor parameters. Using this characteristic change as the alarm parameter is more sensitive. The early warning time for fire alarms will be much earlier than that of other parameter early warnings, and the possibility of preventing a fire is greater.

[0026] The power monitoring controller 12 mainly has two functions. One is to monitor the magnitude of current, the temperature of the cable, and the line voltage. The other is to alarm and control the on / off of the circuit based on the analysis of the magnitude and change of the monitored data. According to the cable characteristics and the set parameters, the thresholds are mainly divided into three levels. The first is the safe level. When the voltage, temperature, and current magnitude and change are all within the safe range, no alarm is given. The second is the early warning level. When the voltage, temperature, and current magnitude and change are outside the safe level but have not reached the set limit values of voltage, temperature, and current, there is a potential risk of electrical fire. It is transmitted to the monitoring and management command platform for early warning and reported to the lowest-level fire handling unit through the transmission network with one key. At this time, according to the actual risk situation, the monitoring and management command platform and the fire handling unit can also choose to cut off the power remotely first and wait for the affiliated fire handling unit to check for potential hazards, so as to pre-check potential hazards and prevent the occurrence of fires. The third level is the risk level. At this time, the voltage, current, or temperature value will exceed the limit value of the cable or design, triggering the alarm unit. It is transmitted to the monitoring and management command platform and the regional fire handling unit for alarm through the transmission network with one key, and a power-off command is directly sent to the controller, and the controller cuts off the circuit.

[0027] The high-temperature fire monitor 13 mainly consists of a monitor and a data analysis server, which can achieve unattended and uninterrupted operation, automatically analyze and judge video image information; timely detect abnormal smoke and early signs of fire in the monitored area, and give fire alarms and fire trend analyses in the fastest and best way; effectively assist firefighters in handling fire crises and minimize false alarms and missed alarms; at the same time, it can also view the real-time image of the scene, directly command and dispatch fire fighting based on the intuitive picture, and can also automatically locate the location, scope, and trend of the fire area and give reasonable fire extinguishing suggestions.

[0028] The monitor can automatically identify residential areas, factory areas, forest areas, cultivated land areas, and special area scenes according to the monitored area and establish a feature database, and set different monitoring levels such as high-risk periods and normal periods according to the risk probability.

[0029] The data analysis server can calculate the geographical location of the fire according to the target area, calculate the length of the fire spread according to the monitoring screen, judge the development trend of the fire according to the local meteorological information and on-site characteristics, and judge the distribution of personnel, property, and dangerous goods around according to the feature information database, which is convenient for the command center and the fire handling unit to make reasonable and comprehensive judgments and reduce the loss of the fire.

[0030] The public monitoring unit 14 mobilizes the power of the public to achieve "joint prevention and control by the masses", improves the monitoring density of people, expands the alarm methods, can be deployed on the mobile phones of the masses, automatically obtains location information according to the mobile phone positioning function, takes fire pictures and videos and other fire information, and transmits it to the monitoring management command platform and the regional fire emergency handling unit for alarm with one key through the transmission network, and timely reminds the surrounding public monitoring units of the risks and fire situations. After the fire alarm and early warning, the information is continuously updated, so that the monitoring management command platform and the regional fire emergency handling unit can obtain on-site information in a timely manner during command and dispatch, ensure scientific and reasonable command and dispatch, and achieve efficient fire extinguishing. In normal times, the public monitoring unit can report the flammable items it knows and file them for record, continuously improve the item fire information database, and conduct control before the fire occurs.

[0031] The monitoring management command platform 2 mainly includes a monitoring module, a management module, a database module, a command module, an effect evaluation module and a system evolution module, and has functions of monitoring, management, database establishment and analysis processing, command, and effect evaluation. The system has perfect functions. The monitoring management command platform adopts a multi-level management method, and different priorities are set for different institutions or units. Any mode of separate vertical management, separate horizontal management, and mixed management of vertical management and horizontal management can be adopted.

[0032] The monitoring module monitors the fire alarm situation in the target area in real time. When the fire monitoring end detects a fire, the monitoring module automatically alarms the duty personnel and locks the nearby area for analysis and processing. The duty personnel can conduct manual command or automatically issue it to the corresponding fire emergency handling unit according to the plan.

[0033] The management module mainly sets up management institution units, management personnel units and management equipment units. The management institution units can set different levels according to different management institutions. Each management institution can set management personnel at different levels, which is suitable for a multi-level grid management system. The management equipment unit conducts online monitoring and management of all node terminal devices. When a device fails, the location and fault information of the faulty device can be clearly displayed on the management equipment management map, and an alarm is issued in a timely manner.

[0034] The database module includes a map database unit, a feature database unit and a fire event information database. The map database unit can build two-dimensional and three-dimensional geographic information databases, and all devices and information are vividly marked on the map. The feature database is analyzed, processed and divided on the map and integrated with the three-dimensional stereoscopic map. When a fire occurs in the target area, not only the geographic information is displayed, but also all nearby relevant information is directly and intuitively and vividly displayed on the map at the same time. The fire event information database records the whole process of the fire event and provides basic data for the effect evaluation module.

[0035] The command module sets up a command and dispatch system, a fire situation status information map, a trend graph, disposal suggestions, and information on the progress of fire disposal units.

[0036] The command and dispatch system can be manually commanded or automated. Ordinary warning information can be automatically notified to relevant fire disposal units for self-inspection and disposal according to the pre-set algorithm, greatly reducing the workload of manual labor. In case of a severe fire situation alarm, manual intervention command can be adopted.

[0037] The command and dispatch system can be linked to the monitoring around the fire to view the on-site situation, providing comprehensive and intuitive on-site information for command and fire disposal.

[0038] The fire situation status information map shows information such as the geographical location of the fire, fire type, fire scope, meteorological information, distribution of surrounding personnel, property distribution, and distribution of dangerous goods.

[0039] The trend graph is a pre-judgment trend graph of the fire development automatically made by the system based on information such as the geographical location of the fire, fire type, fire scope, and meteorological information, for reference by fire disposal units and command personnel.

[0040] Based on the trend graph and information such as the distribution of surrounding personnel, property distribution, and distribution of dangerous goods, the system automatically makes disposal suggestions. The disposal principle is to prioritize all factors, with the highest priority for personnel, and the priorities of factors such as property and dangerous goods being defined according to the actual situation.

[0041] The processing progress and situation of the fire disposal unit are synchronized to the command module in real time for the overall judgment and command of the command center.

[0042] The effect evaluation module evaluates the advantages and disadvantages in the fire disposal process by recording and analyzing various elements such as "people, events, objects, vehicles, time, results (people, finances, materials, impacts)" in each link of the fire disposal, making horizontal comparisons with fire incidents in other regions and vertical comparisons with fire incidents in this region.

[0043] The system evolution module mainly puts forward optimization suggestions for the entire system disposal process based on the system operation status and the analysis results of the effect evaluation module, and can set automatic optimization or manual optimization by decision-makers, continuously improving the disposal and operation efficiency of the entire system, adapting to changes in business and requirements, and making this system have tenacious application vitality through evolution.

[0044] Fire disposal unit 3 mainly includes a fire situation information map, path navigation, fire situation trend and suggestions, and a reporting module. It has functions such as fire situation information display, path navigation, synchronization of fire situation trend and suggestions information, and manual or automatic reporting of processing information to the monitoring and management command center. Fire disposal units are divided into different priorities to adapt to different management models and are under the control and dispatch of the monitoring and management command center.

[0045] The fire situation information map mainly displays the fire situation information of the alarm points and the surrounding characteristic information in a three-dimensional graph. The path navigation automatically allocates the optimal path selection and time judgment from the fire point to the fire situation disposal unit. The fire situation trend and suggestions synchronize the fire situation trend and suggestion information and command orders from the monitoring, management, and command platform to this unit. The reporting module mainly transmits location information, on-site situations, handling situations, etc. to the superiors.

[0046] The path navigation can automatically locate the position of the fire situation disposal unit in real time, automatically select a path in combination with the alarm location provided by the monitoring, management, and command center, and estimate the approximate path time according to the nature of the fire situation disposal unit, saving the operation time of manual inquiry and address input, and reaching the fire scene as soon as possible.

[0047] The fire situation trend and suggestion module can synchronize the information of the monitoring, management, and command center in real time.

[0048] The reporting module mainly transmits the location information, on-site pictures, voices, videos and other on-site situations, handling plans, results and other situations to the superiors.

[0049] The transmission network 4 mainly includes various communication methods such as narrowband Internet of Things, 3G / 4G / 5G mobile Internet, WIFI / bridge, optical fiber / network cable, etc.

[0050] The indoor monitoring sensors and power monitoring controllers require less data traffic and have a wide distribution range. It is more suitable to use the narrowband Internet of Things.

[0051] The high-point fire monitors need to transmit a large amount of data, and the environment where they are located may be complex. The WIFI / bridge and optical fiber / network cable transmission methods are used.

[0052] The public monitoring unit and the fire situation disposal unit need to send or receive on-site information in real time and are widely distributed. The 3G / 4G / 5G mobile Internet transmission method is used.

[0053] The beneficial effects of the present invention:

[0054] A comprehensive smart city fire management system improves the efficiency of fire prevention and disposal in the smart city management area, reduces the probability of fire occurrence, shortens the disposal time, and facilitates a comprehensive grasp of information disposal. Description of the Drawings

[0055] Figure 1 Schematic diagram of the module composition of the comprehensive smart city fire management system. Detailed Implementation Modes

[0056] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0057] To solve the problem of smart city fire prevention within the town area, an embodiment of the present invention adopts a comprehensive smart city fire management system.

[0058] The system mainly includes a fire monitoring terminal 1, a transmission network 4, a monitoring and management command platform 2, and a fire handling unit 3.

[0059] The fire monitoring terminal 1 mainly includes an indoor monitoring sensor 11, a power monitoring controller 12, a high-temperature fire monitor 13, and a public monitoring unit 14.

[0060] The indoor monitoring sensor 11 mainly includes special substance sensors such as a smoke sensor with customized sensitivity, a temperature sensor with customized sensitivity, and a combustible gas sensor.

[0061] The smoke sensor with customized sensitivity is mainly deployed in an enclosed indoor environment and alarms according to the concentration of smoke during a fire. In a smoke-free area, the smoke detector is set to the smoke-free level and will alarm immediately when smoke is detected, enabling quick discovery of a fire. In a high-risk area with a high fire risk, the smoke monitoring sensitivity is appropriately increased. For the smoking level in a family bedroom, the smoke concentration generated during smoking does not trigger an alarm. For the family kitchen level and the commercial kitchen custom level, and for public areas in shopping malls, factory areas, and special places, smoke sensors with different sensitivities need to be selected according to different actual usage situations. When the smoke detector reaches the alarm threshold, it triggers a local alarm through a speaker, shortening the fire monitoring time. When a local alarm is triggered, the fire information is simultaneously sent to the monitoring and management command platform and all levels of fire handling units through the transmission network.

[0062] The temperature sensor with customized sensitivity is mainly used in certain scenarios where substances are not easily ignited to produce smoke, but the temperature has risen to a very high level, presenting a high probability of fire hazards. Since the smoke alarm cannot alarm in time, the temperature sensor needs to set a safe temperature monitoring threshold to give an early warning before a fire occurs, compensating for the risk of failure in fire smoke monitoring.

[0063] The combustible gas sensor selects different gas sensors according to the characteristics of the gas used. In production and life, when the gas leaks to a certain extent, there is no smoke and no temperature rise, but there is a high fire hazard. Smoke monitoring and temperature monitoring can only alarm after a fire occurs, failing to give an early warning to prevent a fire. Selecting a gas sensor can give an early warning before a fire occurs in a timely manner, avoiding the fire risk.

[0064] The special substance sensor mainly gives early warnings in advance according to the characteristic changes of the substance. When a special substance is about to catch fire, the change of characteristic parameters is faster than that of temperature parameters and smoke sensor parameters. Using this characteristic change as the alarm parameter is more sensitive. The early warning time of fire alarm will be much earlier than that of other parameter early warnings, and the possibility of preventing fire occurrence will be greater.

[0065] The power monitoring controller 12 mainly has two functions. One is to monitor the current magnitude, cable temperature and line voltage. The other is to alarm and control the on-off of the circuit according to the analysis of the monitored data magnitude and changes. According to the cable characteristics and the set parameters of the design, it is mainly divided into three levels. The first is the safety level. The voltage, temperature, current magnitude and changes are all within the safe range, and no alarm is given. The second is the early warning level. The voltage, temperature, current magnitude and changes are outside the safety level, but have not reached the set limit values of voltage, temperature and current. There is a potential risk of electrical fire. It is transmitted to the monitoring and management command platform for early warning and reported to the lowest-level fire situation disposal unit of its own through the transmission network with one key. At this time, according to the actual risk situation, the monitoring and management command platform and the fire situation disposal unit can also choose to cut off the power remotely first and wait for the affiliated fire disposal unit to investigate potential hazards, so as to pre-investigate potential hazards and prevent the occurrence of fires. The third level is the risk level. At this time, the voltage, current or temperature value will exceed the limit value of the cable or design, triggering the alarm unit, which is transmitted to the monitoring and management command platform and the regional fire situation disposal unit for alarm through the transmission network with one key, and a power-off command is directly sent to the controller, and the controller cuts off the circuit.

[0066] The voltage generally fluctuates within a certain range, which is normal. During the actual power consumption process, there may be high voltage and low voltage, causing the equipment to operate within the non-working voltage safety range. If the equipment runs for a long time, there will be a certain risk of electrical fire, reminding the relevant person in charge of a certain equipment operation risk.

[0067] If the current suddenly increases, it may be that electrical equipment has been added. The fire situation disposal unit notifies the affiliated fire situation disposal unit to confirm. If it is true, it is normal. If it is not true, it may be a line hidden danger or someone has privately added electrical equipment. Remind the person in charge to conduct a check and eliminate the fire risk at the budding stage.

[0068] The high-precision fire monitor 13 mainly consists of a monitor and a data analysis server, which can work unattended and continuously, automatically analyze and judge video image information, promptly detect abnormal smoke and early signs of fire in the monitored area, give fire alarms and analyze the fire situation in the fastest and best way, effectively assist firefighters in handling fire crises, and minimize false alarms and missed alarms. At the same time, it can also view real-time images of the scene, directly command and dispatch fire fighting based on the intuitive pictures, automatically locate the position, scope and trend of the fire area, and give reasonable fire fighting suggestions.

[0069] The monitor can automatically identify scenes such as residential areas, factory areas, forest areas, cultivated land areas and special areas according to the monitored area, establish a feature database, and set different monitoring levels such as high-risk periods and normal periods according to the risk probability.

[0070] The data analysis server can calculate the fire geographical location according to the target area, calculate the fire spread length according to the monitoring video, judge the fire development trend according to the local meteorological information and on-site characteristics, and judge the distribution of people, property and dangerous goods around according to the feature information database, which is convenient for the command center and the fire situation disposal unit to make reasonable and comprehensive judgments and reduce the loss of the fire.

[0071] According to the geographical coordinates of this monitoring point, the height h of the monitoring point, the rotation angle v and the pitch angle m of the monitoring point, and the focal length of the monitoring point, calculate the fire geographical location. The distance l between the fire location and the monitoring point is l = h * tan(m). Combine the recognition range of the image to calculate the fire spread length and area, combine the time factor to calculate the spread of the fire situation, combine meteorological factors such as wind, temperature, rainfall and snow to predict the fire trend, and give fire situation disposal suggestions based on the feature information database.

[0072] The public monitoring unit 14 mobilizes the power of the public to achieve "joint prevention and control by the masses", improves the monitoring density of people and expands the alarm methods. It can be deployed on the mobile phones of the masses. According to the mobile phone positioning function, it automatically obtains the positioning information, takes fire pictures and videos and other fire information, and synchronizes them to the monitoring management command platform and the regional fire situation disposal unit for alarm through the transmission network with one key. It also timely reminds the surrounding public monitoring units of the risks and fire situations. After the fire alarm and early warning, the information is continuously updated, so that the monitoring management command platform and the regional fire situation disposal unit can obtain on-site information in time during command and dispatch, ensure scientific and reasonable command and dispatch, and achieve efficient fire fighting. In normal times, the public monitoring unit can report the flammable items it knows and file them for record, continuously improve the item fire information database, and conduct control before the fire occurs.

[0073] The monitoring, management, and command platform 2 mainly includes a monitoring module, a management module, a database module, a command module, an effect evaluation module, and a system evolution module, and has functions such as monitoring, management, database establishment and analysis processing, command, and effect evaluation. The system has perfect functions. The monitoring, management, and command platform adopts a multi-level management method, and different priorities are set for different institutions or units. Any mode of separate vertical management, separate horizontal management, or a combination of vertical and horizontal management can be adopted.

[0074] The monitoring module monitors the fire alarm situation in the target area in real time. When a fire is detected by the fire monitoring terminal, the monitoring module automatically alarms the duty personnel and locks the nearby area for analysis and processing. The duty personnel can conduct manual command or automatically send it to the corresponding fire handling unit according to the pre-set plan.

[0075] The management module mainly sets up management institution units, management personnel units, and management equipment units. The management institution units can set different levels according to different management institutions. Each management institution can set management personnel at different levels, which is suitable for a multi-level grid management system. The management equipment unit conducts online monitoring and management of all terminal devices of all nodes. When a device fails, the location and fault information of the faulty device can be clearly displayed on the management equipment management map, and an alarm is given in a timely manner.

[0076] The database module includes a map database unit, a feature database unit, and a fire event information database. The map database unit can build two-dimensional and three-dimensional geographic information databases, and all devices and information are vividly marked on the map. The feature database is analyzed, processed, and divided on the map and integrated with the three-dimensional map. When a fire occurs in the target area, not only geographical information is displayed, but also all nearby relevant information is directly and intuitively displayed on the map at the same time. The fire event information database records the entire process of fire events and provides basic data for the effect evaluation module.

[0077] The command module sets up a command and dispatch system, a fire situation information map, a trend map, disposal suggestions, and information on the progress of the fire handling unit.

[0078] The command and dispatch system can conduct manual command or automated command. Ordinary early warning information can be automatically notified to the relevant fire handling units for self-inspection and disposal according to the pre-set plan algorithm, greatly reducing the workload of manual labor. Manual intervention command can be adopted in case of severe fire situation alarms.

[0079] The command and dispatch system can be linked to the monitors around the fire to view the on-site situation, providing comprehensive and intuitive on-site information for command and fire disposal.

[0080] The fire situation information map displays information such as the geographical location information of the fire, the type of fire, the scope of the fire, meteorological information, the distribution of surrounding personnel, the distribution of property, and the distribution of dangerous goods.

[0081] The trend chart is a pre-judgment trend chart of the development of the fire situation automatically made by the system based on the geographical location information of the fire, the type of fire, the scope of the fire, meteorological information, etc., for the reference of the fire situation disposal unit and the command personnel.

[0082] Based on the trend chart and information such as the distribution of surrounding personnel, property, and dangerous goods, the system automatically makes disposal suggestions. The disposal principle is to prioritize all factors, with personnel having the highest priority, and the priorities of factors such as property and dangerous goods being defined according to the actual situation.

[0083] The processing progress and situation of the fire situation disposal unit are synchronized to the command module in real time for the overall judgment and command of the command center.

[0084] The effect evaluation module evaluates the advantages and disadvantages in the fire disposal process by recording and analyzing various elements such as "people, events, objects, vehicles, time, results (people, property, objects, impacts)" in each link of the fire disposal, making horizontal comparisons with fire situation events in other regions and vertical comparisons with fire situation events in this region.

[0085] The system evolution module mainly puts forward suggestions for optimizing the disposal process of the entire system according to the system operation status and the analysis results of the effect evaluation module, and can set automatic optimization and manual optimization by the decision-maker, continuously improving the disposal and operation efficiency of the entire system, adapting to changes in business and requirements, and enabling this system to have tenacious application vitality through evolution.

[0086] The fire situation disposal unit 3 mainly includes a fire situation information map, path navigation, fire situation trend and suggestions, and a reporting module. It has functions such as displaying fire situation information, path navigation, synchronizing fire situation trend and suggestions information, and manually or automatically reporting processing information to the monitoring and management command center. The fire situation disposal unit is divided into different priorities to adapt to different management modes and is under the control and scheduling of the monitoring and management command center.

[0087] The fire situation information map mainly displays the fire situation information of the alarm point and the surrounding characteristic information in a three-dimensional graphic. The path navigation automatically allocates the optimal path selection and time judgment from the fire point to the fire situation disposal unit. The fire situation trend and suggestions synchronize the fire situation trend and suggestions information and command orders from the monitoring and management command platform to this unit. The reporting module mainly transmits location information, on-site situation, processing situation, etc. to the superior.

[0088] The path navigation can automatically locate the position of the fire situation disposal unit in real time, automatically select a path in combination with the alarm location provided by the monitoring and management command center, and estimate the approximate path time according to the nature of the fire situation disposal unit, saving the manual operation time and reaching the fire scene as soon as possible.

[0089] The fire situation trend and suggestions module can synchronize the information of the monitoring and management command center in real time.

[0090] The reporting module is mainly used to report the on-site situation such as the location information, on-site pictures, voice, video, etc., as well as the handling solutions and results to the superiors.
