Description

Technical Field

[0001] The present invention relates to the field of fire protection joint control computer control technology, and in particular to a gas control method and a fire protection pipeline system, device and storage medium. Background Art

[0002] Firefighting gases such as nitrogen and carbon dioxide are used in firefighting, and their effects in extinguishing fire and preventing the spread of fire are significant.

[0003] The manufacturer is considering installing fire gas fire extinguishers in the corridor. When a fire occurs, the fire gas fire extinguishers in each indoor area are opened to release fire gas, reducing the oxygen concentration in the space, thereby extinguishing the fire or delaying the fire. However, in actual applications, when a fire occurs, there are still people in the corridor. The release of fire gas reduces the oxygen concentration, and the smoke in the fire will put the escapees in a harsh environment. If used during the day when people are awake, the escapees can escape while the fire gas spreads to various areas. However, when people are asleep, even if a fire alarm sounds, they cannot respond immediately. If the fire gas is activated at this time, the people are likely to suffocate in their sleep. Therefore, the use of fire gas actually reduces the chance of survival. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a gas control method and a fire-fighting pipeline system, device, and storage medium to reasonably release fire-fighting gas, automatically form an environment suitable for personnel escape and delay fire, and provide conditions for safe rescue.

The gas tank is docked, and the outlet end is docked with the outlet of the indoor area. The switching air-regulating component includes at least a first ventilation state and a second ventilation state and can switch between each other. In the first ventilation state, the first air inlet end and the air outlet end are connected, and the second air inlet end and the air outlet end are disconnected. In the second ventilation state, the first air inlet end and the air outlet end are disconnected, and the second air inlet end and the air outlet end are connected; the control module is electrically connected to each detection component and the switching air-regulating component respectively, and the control module executes a gas control method, which includes: continuously monitoring the smoke concentration signal uploaded by each smoke sensor; when the smoke concentration signal exceeds the fire smoke concentration signal, the smoke concentration signal is automatically controlled. concentration threshold, send a fire alarm message, and derive the indoor area where the fire occurs according to the smoke sensor that uploads the smoke concentration signal that exceeds the fire smoke concentration threshold; obtain the human biological signal uploaded by each human detection component, wherein the human biological signal is used to characterize whether there is a person in the indoor area where the human detection component is located; divide each indoor area into a first indoor area where no person exists and a second indoor area where a person exists according to the human biological signal uploaded by each human detection component; switch the switching air conditioning component of the first indoor area to the second ventilation state, and adjust the outlet flow rate of the fire-fighting gas so that the oxygen concentration of the indoor area drops to below the first indoor area. an oxygen concentration threshold; determining whether the indoor interval on fire belongs to the second indoor interval, and if so, switching the switching air conditioning component of the indoor interval on fire between the first ventilation state and the second ventilation state, and adjusting the outlet flow rate of the fire-fighting gas and / or air so that the oxygen concentration of the indoor interval is maintained at the second oxygen concentration threshold; switching the switching air conditioning component of the second indoor interval that is not on fire to the first ventilation state, and adjusting the outlet flow rate of the air so that the oxygen concentration of the indoor interval is maintained at a third oxygen concentration threshold, wherein the first oxygen concentration threshold is less than the second oxygen concentration threshold, and the second oxygen concentration threshold is less than the third oxygen concentration threshold.

[0006] A gas control method according to an embodiment of the present invention has at least the following beneficial effects:

[0007] In the present gas control method, the first air inlet end of the switching air conditioning component is connected to the fan of the air conditioning system, and the air outlet of the switching air conditioning component is connected to the air outlet of the central air conditioning in the indoor area. When no fire occurs, each switching air conditioning component is in the first ventilation state, and the air conditioning system outputs airflow through the air outlet of each indoor area to adjust the ambient temperature of the indoor area. Each smoke sensor detects the smoke concentration of each indoor area accordingly. When the smoke concentration exceeds the fire smoke concentration threshold, it proves that a fire has occurred, and a fire alarm message is immediately triggered. The fire alarm message can be sent to each user's mobile phone through the cloud server to notify personnel to evacuate. Of course, some personnel may fail to check the fire alarm message in time and fail to evacuate immediately. Therefore, firstly, the indoor area where the fire occurs is obtained according to the smoke sensor that uploads the smoke concentration signal exceeding the fire smoke concentration threshold, and at the same time, each indoor area is divided into a first indoor area and a second indoor area according to the human biological signal fed back by each human detection component. For the first indoor area where no one is present, regardless of whether there is a fire or not, the air conditioning component is switched to the second ventilation state, and the oxygen concentration of the indoor area drops to below the first oxygen concentration threshold. The first oxygen concentration threshold is much lower than the oxygen concentration in normal air. If the indoor area is on fire, the oxygen concentration of the indoor area can be reduced to extinguish the fire and hinder the spread of the fire as much as possible. If the indoor area is not on fire, the fire is not easy to spread to the area with lower oxygen concentration. The indoor interval of the fire is reduced to reduce the possibility of ignition of objects in the indoor interval caused by nearby fire. As for the second indoor interval where people are present, it is first determined whether the indoor interval where the fire breaks out belongs to the second indoor interval. If it does, while hindering the burning of the fire, it is necessary to consider the basic oxygen supply needs for maintaining the survival of personnel, and switch the air conditioning component between the first ventilation state and the second ventilation state, and at the same time adjust the outlet flow rate of the fire-fighting gas and / or air so that the oxygen concentration in the indoor interval is maintained at the second oxygen concentration threshold value. The second oxygen concentration threshold value is slightly lower than the oxygen concentration in normal air, which can meet the basic oxygen supply needs of the personnel in the indoor interval, and because the indoor interval has been on fire, the personnel in the indoor interval will also be relatively safe. If the fire is discovered early, the evacuation time will be relatively early. In addition, the oxygen concentration in the air is appropriately reduced to hinder the spread of the fire. After the personnel are evacuated, the oxygen concentration can be reduced to the first oxygen concentration threshold as soon as possible. For the second indoor area where no fire has occurred, it is not easy for personnel to find the fire. Considering that the personnel are sleeping soundly, normal air circulation is required here. The air conditioning component is switched to the first ventilation state to maintain the oxygen concentration in the indoor area at the third oxygen concentration threshold to ensure the normal oxygen supply needs of the personnel and prevent the suffocation of the personnel due to the use of fire-fighting gas. This design reasonably releases the fire-fighting gas to automatically form an environment suitable for personnel escape and delay the fire, providing conditions for safe rescue.

The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0032] like Figures 1 to 5 As shown, a gas control method according to an embodiment of the first aspect of the present invention is applied to a fire protection pipeline system, wherein the fire protection pipeline system includes a gas storage tank 110, multiple detection components 120, multiple switching gas adjustment components 130 and a control module 140, the gas storage tank 110 is used to store fire protection gas for fire protection, and multiple detection components 120 are respectively arranged in each indoor interval, the detection component 120 includes a smoke sensor 121, a human body detection component 122 and an oxygen concentration sensor 123, and the switching gas adjustment components 130 are arranged in each indoor interval one by one, and each switching gas adjustment component 130 includes a first air inlet end, A second air inlet end and an air outlet end, the first air inlet end is connected to the fan of the air conditioning system, the second air inlet end is connected to the gas storage tank 110, and the air outlet end is connected to the air outlet 160 in the indoor area. The switching air conditioning component includes at least a first ventilation state and a second ventilation state and can switch between each other. In the first ventilation state, the first air inlet end and the air outlet end are connected, and the second air inlet end and the air outlet end are disconnected. In the second ventilation state, the first air inlet end and the air outlet end are disconnected, and the second air inlet end and the air outlet end are connected; the control module is electrically connected to each detection component and the switching air conditioning component, and the control module executes the gas control method.

[0033] It should be noted that the fire protection pipe system can be used in the fire protection control of buildings, such as Figure 1 Taking the floor plan of as an example, many buildings now have central air-conditioning systems. Usually, multiple indoor areas in the building plan include the hall, living room, master bedroom, first bedroom, second bedroom, kitchen, etc., and each indoor area is basically provided with an air outlet 160. The air-conditioning system usually includes a fan, a refrigeration device and an air duct shell connected to each air outlet 160. The fan guides the air flow to pass through the refrigeration end of the refrigeration device, and then guides the air flow to each air outlet 160 through the air duct shell. A regulating valve is provided near each air outlet 160. The regulating valve is used to control the size of the air flow. In this design, the fire protection pipe system is installed in the air-conditioning system, and the switching air conditioning component can select a three-position three-way solenoid valve, and the regulating valve is replaced by each switching air conditioning component.

[0034] The gas storage tank 110 may be a high-pressure gas storage tank 110 , which may compress and store a large amount of firefighting gas to meet the demand of filling the indoor area. Specifically, the firefighting gas may include nitrogen, carbon dioxide, and the like.

[0035] The human body detection device can use a pyroelectric scanning radar installed on the top of the indoor area to facilitate scanning of the indoor area to detect whether there is a human biological reaction. Each indoor area is also equipped with a smoke sensor and an oxygen concentration sensor to detect the smoke concentration and oxygen concentration of the indoor area.

[0036] Among them, the control module may include an MCU or a CPU and its associated circuits. The control module can be connected to the monitoring background through a bus. When a fire alarm is triggered, the fire alarm information can be sent to the monitoring background, and the monitoring background will issue a warning. At the same time, it can be sent to each user's mobile phone via SMS, WeChat, etc. to remind, evacuate and evacuate the user.

[0037] like Figure 4 As shown, the gas control method includes:

[0038] S410, continuously monitoring the smoke concentration signal uploaded by each smoke sensor;

[0039] S420, when the smoke concentration signal exceeds the fire smoke concentration threshold, a fire alarm message is sent, and the indoor area where the fire occurs is obtained according to the smoke sensor that uploads the smoke concentration signal exceeding the fire smoke concentration threshold;

[0040] S430, obtaining human biological signals uploaded by each human detection component, wherein the human biological signals are used to indicate whether there is a person in the indoor area where the human detection component is located;

[0041] S440, dividing each indoor area into a first indoor area 210 where no human beings exist and a second indoor area 220 where human beings exist according to the human biological signals uploaded by each human body detection element;

[0042] S450, switching the switching air conditioning component of the first indoor interval 210 to the second ventilation state, and adjusting the outlet flow rate of the firefighting gas so that the oxygen concentration in the indoor interval decreases to be lower than the first oxygen concentration threshold;

[0043] S460, determining whether the indoor area where the fire occurs belongs to the second indoor area 220, and if so, switching the air conditioning component of the indoor area where the fire occurs between the first ventilation state and the second ventilation state, and adjusting the outlet flow rate of the fire-fighting gas and / or air so that the oxygen concentration of the indoor area is maintained at the second oxygen concentration threshold;

[0044] S470, switch the switching air conditioning component of the second indoor interval 220 where no fire has occurred to the first ventilation state, and adjust the air outlet flow rate so that the oxygen concentration in the indoor interval is maintained at a third oxygen concentration threshold, wherein the first oxygen concentration threshold is less than the second oxygen concentration threshold, and the second oxygen concentration threshold is less than the third oxygen concentration threshold.

[0045] It should be noted that for the regulation of the outlet flow rate of fire-fighting gas and / or air, the switching air regulating component selects a three-position three-way solenoid valve. When the switching air regulating component is switched to the first ventilation state, the control module can control the opening of the switching air regulating component to adjust the flow rate of air flowing through. Similarly, when the switching air regulating component is switched to the second ventilation state, the control module can control the opening of the switching air regulating component to adjust the flow rate of fire-fighting gas flowing through.

[0046] In the present gas control method, the first air inlet end of the switching air conditioning component is connected to the fan of the air conditioning system, and the air outlet 160 of the switching air conditioning component is connected to the air outlet of the central air conditioning in the indoor area. When no fire occurs, each switching air conditioning component is in the first ventilation state, and the air conditioning system outputs airflow through the air outlet of each indoor area to adjust the ambient temperature of the indoor area. Each smoke sensor detects the smoke concentration of each indoor area accordingly. When the smoke concentration exceeds the fire smoke concentration threshold, it proves that a fire has occurred, and a fire alarm message is immediately triggered. The fire alarm message can be sent to each user's mobile phone through the cloud server to notify personnel to evacuate. Of course, some personnel may fail to check the fire alarm message in time and fail to evacuate immediately. Therefore, firstly, the indoor area where the fire occurs is obtained according to the smoke sensor that uploads the smoke concentration signal exceeding the fire smoke concentration threshold, and at the same time, the indoor areas are divided into the first indoor area 210 and the second indoor area 220 according to the human biological signals fed back by the human body detection parts. For the first indoor area 210 where no one is present, regardless of whether there is a fire or not, the air conditioning component is switched to the second ventilation state, and the oxygen concentration in the indoor area drops to below the first oxygen concentration threshold, which is much lower than the oxygen concentration in normal air. If the indoor area is on fire, the oxygen concentration in the indoor area can be reduced to extinguish the fire and hinder the spread of the fire as much as possible. If the indoor area is not on fire, the fire is not easy to spread to the oxygen concentration threshold. The lower indoor interval reduces the possibility of nearby fires causing ignition of objects in the indoor interval. As for the second indoor interval 220 where people are present, it is first determined whether the indoor interval where the fire occurs belongs to the second indoor interval 220. If it does, while hindering the burning of the fire, it is necessary to consider the basic oxygen supply needs for maintaining the survival of personnel, and switch the air conditioning component between the first ventilation state and the second ventilation state, and at the same time adjust the outlet flow rate of the fire-fighting gas and / or air so that the oxygen concentration in the indoor interval is maintained at the second oxygen concentration threshold value, which is slightly lower than the oxygen concentration in normal air and can meet the basic oxygen supply needs of the personnel in the indoor interval. Moreover, since the indoor interval has been on fire, the personnel in the indoor interval The occurrence of fire will also be discovered earlier, and the evacuation time will be relatively early. In addition, the oxygen concentration in the air is appropriately reduced to hinder the spread of fire. After the personnel are evacuated, the oxygen concentration can be reduced to the first oxygen concentration threshold as soon as possible. For the second indoor interval 220 where no fire has occurred, it is not easy for personnel to discover the fire. Considering that the personnel are sleeping soundly, normal air circulation is required here, and the air conditioning component is switched to the first ventilation state to maintain the oxygen concentration in the indoor interval at the third oxygen concentration threshold to ensure the normal oxygen supply needs of the personnel and prevent the suffocation of the personnel due to the use of fire-fighting gas. This design reasonably releases the fire-fighting gas, automatically forms an environment suitable for the escape of personnel and delays the fire, and provides conditions for safe rescue.

[0047] like Figure 1 As shown, for some indoor intervals that are opposite or connected to each other, such as a hall and a living room, two rooms with opposite doors, etc., there is a large area for gas exchange between the two. Therefore, when a large amount of firefighting gas is released in one room, the firefighting gas will flow toward the other room, so that if there is someone in the other room, no matter how much air is output from the other room, the oxygen concentration will be reduced to a lower level. Therefore, in some embodiments of the present invention, there is at least one gas balance interval group in each indoor interval, and each gas balance interval group includes two paired indoor intervals. The gas control method also includes:

[0048] When one indoor interval in the gaseous balance interval group is the first indoor interval 210, and the other indoor interval is the second indoor interval 220, the ratio of the outlet flow rate of the air in the second indoor interval 220 to the outlet flow rate of the fire-fighting gas in the first indoor interval 210 is adjusted so that the oxygen concentration in the second indoor interval 220 is maintained at the third oxygen concentration threshold.

[0049] When installing the fire protection pipe system for this apartment, the staff needs to set which indoor intervals are paired with each other in the system of the control module to form a gas balance interval group.

[0050] For two indoor intervals in the gaseous balance interval group, when one of them is the first indoor interval 210 and the other indoor interval is the second indoor interval 220, when the oxygen concentration in the second indoor interval 220 is low and needs to be increased, the control module not only needs to increase the air outlet flow rate of the switching air conditioning component of the second indoor interval 220, but also needs to reduce the air outlet flow rate of the fire gas of the switching air conditioning component of the first indoor interval 210 in the gaseous balance interval group, which is specifically equivalent to adjusting the ratio of the air outlet flow rate of the second indoor interval 220 to the air outlet flow rate of the fire gas of the first indoor interval 210.

[0051] During the escape process, the escape route may need to pass through the first indoor interval 210. In the first indoor interval 210, the oxygen concentration is low. When the escapee is suddenly stranded during the escape process, suffocation is likely to occur. Therefore, in some embodiments of the present invention, Figure 5 As shown, the gas control method also includes:

[0052] S510, when a request for escape of a person is obtained;

[0053] S520, according to the escape request of the person, the indoor area where the escaped person is located is obtained;

[0054] S530, analyzing the escape route and multiple indoor sections that the escape route passes through based on the indoor section where the escapee is located and the escape exit 230 based on the apartment distribution map;

[0055] S540, the oxygen concentration in the second indoor area 220 passed by the escape route continues to be maintained at the third oxygen concentration threshold;

[0056] S550, raising the oxygen concentration in the first indoor area 210 passed by the escape route to approach a second oxygen concentration threshold;

[0057] S560: Output escape route information and escape permission instruction.

[0058] The escapee can wirelessly send an escape request to the cloud server through a mobile phone or other smart device, and the cloud server then sends the escape request to the corresponding control module. The mobile phone is also provided with positioning information, and the control module can thereby derive the indoor interval where the escapee is located. When installing the fire protection pipe system, the staff has already entered the household distribution map into the working system of the control module. The control module can analyze which indoor intervals the escapee needs to pass through from the indoor interval where the escapee is located to the escape exit 230 based on the household distribution map. Among these indoor intervals, some may be the first indoor interval 210, and some may be the second indoor interval 220. If it is the second indoor interval 220, it proves that there are still people in this indoor interval, and thus the oxygen concentration continues to be maintained at the third oxygen concentration threshold. If it is the first indoor interval 210, the oxygen concentration needs to be increased to approach the second oxygen concentration threshold first, and then the escape route and the escape permission instruction are sent to the escapee. The escapee immediately makes an escape action after receiving the escape permission instruction.

[0059] In some embodiments of the present invention, the step of increasing the oxygen concentration in the first indoor interval 210 passed by the escape route to approach the second oxygen concentration threshold value includes:

[0060] Switching the switching air conditioning component of the first indoor zone 210 from the second ventilation state to the first ventilation state, and recording the switching time value;

[0061] When the switching time value reaches the ventilation estimated time threshold, the step of outputting escape route information and escape permission instructions is entered.

[0062] In order to buy escape time for the escapees, after the switching air conditioning component of the first indoor interval 210 is switched from the second ventilation state to the first ventilation state, the air outlet outputs air to the first indoor interval 210, but the oxygen concentration in the space may not be able to rise to the second oxygen concentration threshold immediately. The specific rising speed depends on the actual scenario, and air will continue to be output to the first indoor interval 210 in the future. Therefore, in this process, there is no need to wait until the oxygen concentration is fully increased to the second oxygen concentration threshold. Instead, the switching time value is recorded after the switching air conditioning component of the first indoor interval 210 is switched from the second ventilation state to the first ventilation state. After the switching time value reaches the ventilation estimated time threshold, the escapees can be notified to start evacuating. Specifically, the ventilation estimated time threshold can be 10s, 15s, 20s, etc., which is set by the staff.

[0063] In some embodiments of the present invention, the escape route and the multiple indoor sections through which the escape route passes are analyzed based on the indoor section where the escapee is located and the escape exit 230 based on the apartment distribution map, including:

[0064] The output shows the indoor area where the escapee is located, the escape exit 230, and the distribution map of the apartment types;

[0065] Obtaining an interval selection instruction, wherein the interval selection instruction is used to select an indoor interval of at least one route;

[0066] An escape route is planned according to the indoor area where the escapee is located, the escape exit 230 and the indoor areas along the way, and multiple indoor areas passed by the escape route are obtained.

[0067] The escapees are at the scene and have a better understanding of the on-site environment. Therefore, an opportunity is provided here for the escapees to adjust the escape route according to the actual situation. The control module outputs data to the smart device to present the indoor area where the escapees are located, the escape exit 230 and the apartment distribution map. The escapees can select the indoor area of ​​the route, and then the control module generates an escape route according to the area selection instruction selected by the escapees, and obtains the multiple indoor areas passed by the escape route to control the switching air conditioning components of these indoor areas.

[0068] In some embodiments of the present invention, the switching air conditioning component of the first indoor interval 210 is switched to the second ventilation state, and the outlet flow rate of the fire fighting gas is adjusted so that the oxygen concentration in the indoor interval decreases to be lower than the first oxygen concentration threshold value, which includes:

[0069] After the switchable air conditioning component of the first indoor area 210 is switched to the second ventilation state, the firefighting gas is output to the indoor area at the first outlet gas flow rate;

[0070] After the oxygen concentration in the indoor area drops to reach a first oxygen concentration threshold, the firefighting gas is output to the indoor area at a second outlet gas flow rate, wherein the first outlet gas flow rate is greater than the second outlet gas flow rate.

[0071] It is understandable that the weight of some fire-fighting gases is less than that of air, and the air outlet 160 is generally installed above the indoor interval. The fire-fighting gas will float on the top of the indoor interval, and the fire-fighting purpose cannot be achieved. Therefore, in the first indoor interval 210, when the air conditioning component is switched to the second ventilation state at the beginning, the oxygen concentration in the first indoor interval 210 is relatively high. At this time, the output of the fire-fighting gas is controlled by a higher first air outlet flow rate. The impact of the fire-fighting gas output is used to allow the fire-fighting gas to sink and diffuse to more areas of the indoor interval. When the oxygen concentration in the indoor interval drops to reach the first oxygen concentration threshold, the first air outlet flow rate is changed to the second air outlet flow rate to maintain the output of the fire-fighting gas to the indoor interval. The second gas storage flow rate is relatively slow, which can reasonably maintain the oxygen concentration in the indoor interval so that the oxygen concentration is lower than the first oxygen concentration threshold, but will not cause excessive consumption of the fire-fighting gas.

The detection component 120 includes a smoke sensor 121, a human body detection component 122 and an oxygen concentration sensor 123. The switching gas adjustment components 130 are arranged in each indoor interval one by one.
