All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the invention may be practiced other than those illustrated or described herein, and that the words "first", "second", etc. do not necessarily distinguish one element from another, but rather denote any number of elements, e.g., a first element may be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
Among various disasters, a fire disaster is one of the most common main disasters threatening public safety and social development, and when a fire disaster occurs, huge economic losses are often caused. The fire disaster is divided into a fire disaster occurring in an indoor scene and a fire disaster occurring in an outdoor scene, and for the fire disaster occurring in the indoor scene, when the fire disaster occurs, the fire can be extinguished through a fire-fighting spraying system; for the fire disaster that outdoor scene took place, especially this kind of environment that has more combustible substance of traditional wooden structure village, under the influence that receives the strong wind weather, the spreading of condition of a fire is comparatively rapid, and traditional village outdoor scene can't install fire sprinkler system, leads to the conflagration that outdoor scene took place, and the condition of a fire is very difficult to control.
Moreover, the fire-fighting spraying system used in the indoor scene cannot accurately spray the fire extinguishing agent to the fire area due to the fact that the fire-fighting spraying system does not have the recognition function, the spraying range of the fire extinguishing agent is large, and the fire-fighting spraying system is not suitable for the indoor scene with more electronic equipment.
Aiming at the limitation of the prior art, the invention provides a fire extinguishing method which can determine a fire passing area and a possible fire spreading area when a fire disaster occurs, control fire extinguishing equipment to spray fire extinguishing agents to the fire passing area and the fire spreading area, effectively prevent the fire spreading while extinguishing the fire, greatly improve the fire extinguishing efficiency and reduce the economic loss caused by the fire disaster.
The fire extinguishing method provided by the embodiment of the invention is described in detail by specific embodiments and application scenarios thereof with reference to the attached drawings.
As shown in fig. 1, an embodiment of the present invention provides a fire extinguishing method, which may include the following steps 101 to 103:
Wherein the prevention and control area includes: a first region and a second region. The first area is a fire passing area, and the second area is a fire spreading area. The environmental parameters include: wind direction and wind speed.
Illustratively, the fire passing area is an area where a fire occurs, and the fire spreading area is a possible fire spreading area predicted based on the wind direction and the wind speed of the current environment.
It can be understood that when a fire disaster occurs, the fire condition is influenced by weather, the spreading speed of the fire condition is high, and the fire condition is difficult to be effectively controlled only aiming at the fire extinguishing action of a fire passing area. Therefore, the possible spreading area of the fire can be predicted according to the wind direction and the wind speed of the former environment, and the flame retardant zone is established on the spreading area to play a role in blocking the spreading of the fire.
Illustratively, the fire extinguishing apparatus may include: the remote fire extinguishing equipment comprises a folding arm support, a rotating arm support, a water spraying suspension and the like, and the direction of the remote fire extinguishing equipment can be adjusted.
For example, the step of determining the first area in step 101 may include the following steps 101a1 and 101a2:
101a1, acquiring monitoring information fed back by at least one fire detection sensor.
And step 101a2, under the condition that the monitoring information indicates that a fire occurs, determining the position information of the fire point corresponding to each sensor according to the position information of each sensor in the target sensors.
And step 101a3, determining the first area according to the position information of the ignition point corresponding to each sensor.
Wherein the object sensor is a sensor that detects a fire among the at least one fire detection sensor. The object sensor may include at least one fire sensor.
Illustratively, the fire detection sensor is a device for detecting a fire and finding out a fire in a fire-fighting automatic fire alarm system, and is used for monitoring whether a fire occurs in an environment. The fire detection sensor may include: temperature sensors, smoke sensors, radiant light intensity sensors, and the like. The fire detection sensor can convert characteristic physical quantities of fire, such as temperature, smoke, gas and radiation intensity, into electric signals and send alarm signals, namely the monitoring information, to an automatic fire alarm system.
For example, the fire protection fire automatic alarm system may determine an ignition point based on location information of a fire detection sensor transmitting an alarm signal after receiving the alarm signal transmitted from the fire detection sensor. After that, the overfire region, i.e. the above-mentioned first region, can be accurately calculated from a plurality of ignition points.
Specifically, the position information of the temperature sensor that detects a high temperature may be used to determine the position information of the ignition point, and the fire passing area may be further determined by the radiant light intensity sensor.
For example, in order to be able to accurately calculate the fire passing area, it is necessary to establish a coordinate system for a site where fire detection sensors are provided and determine three-dimensional coordinates of each fire detection sensor. When a fire disaster occurs, the fire passing area can be determined according to the three-dimensional coordinates of the target sensor.
For example, as shown in fig. 2, taking a fire extinguishing system formed by arranging fire detecting sensors in villages and using arm supports as fire extinguishing equipment as an example, a spatial coordinate system of a village area is constructed according to longitude and latitude coordinates of the villages and a topographic map, and three-dimensional coordinates of electrical fire monitoring equipment (namely, the fire detecting sensors comprise a smoke alarm, a gas detector and the like) are determined based on the coordinate system. When the fire detection sensor detects that a fire occurs, the area where the fire occurs can be determined according to the position coordinates of the fire detection sensor.
For example, the step of determining the second area in step 101 may include the following steps 101b1 and 101b2:
step 101b1, according to the wind direction of the current environment, determining a second area which is adjacent to the first area and is along the direction indicated by the wind direction.
And step 101b2, determining the area of the second area according to the wind speed of the current environment.
For example, after the first area is determined, the possible spread area of the fire may be determined according to the wind direction and the wind speed of the current environment collected by the sensor. Specifically, the position of the spreading area relative to the fire passing area can be determined according to the wind direction of the current environment, and further, the area size of the spreading area is determined according to the wind speed of the current environment, and the flame retardant zone is established based on the spreading area.
It can be understood that the higher the wind speed of the current environment is, the higher the speed of fire spreading is, and at this time, fire extinguishing agent needs to be sprayed to a larger area of spreading area to ensure that the fire cannot cross the spreading area and spread to other areas.
And 102, determining target equipment according to the prevention and control distance of each fire extinguishing equipment in at least one fire extinguishing equipment.
For example, the installation position of the at least one fire extinguishing apparatus may be determined according to the distribution of the objects to be monitored and the control distance of the fire extinguishing apparatus. The target to be monitored can be a building in an outdoor scene, and can also be equipment such as tables, chairs and the like in an indoor scene.
It can be understood that, in order to realize the full coverage of the area, the installation position of the fire extinguishing apparatus needs to be reasonably planned according to the distribution situation of the targets to be monitored and the prevention and control distance of the fire extinguishing apparatus, so as to ensure that each target to be monitored is within the prevention and control range of the fire extinguishing apparatus. Wherein more fire extinguishing equipment can be arranged according to the importance degree, the important target or the important area.
Illustratively, the target device includes: a first target device and a second target device.
Illustratively, for the first area and the second area, different fire extinguishing devices may be used for rescue, and the step 102 may include the following steps 102a1 to 102a3:
102a1, determining the prevention and control range of each fire extinguishing apparatus according to the second position information of each fire extinguishing apparatus in the at least one fire extinguishing apparatus and the prevention and control distance of each fire extinguishing apparatus.
And 102a3, determining the fire extinguishing equipment with the control range overlapping with the first area as the first target equipment.
And 102a3, determining the fire extinguishing equipment with the control range overlapping with the second area as the second target equipment.
Illustratively, the second position information is three-dimensional coordinate information of the fire extinguishing apparatus located in the coordinate system. And determining the prevention and control range of each fire extinguishing device according to the three-dimensional coordinate information of each fire extinguishing device and the prevention and control distance of each fire extinguishing device.
For example, as shown in fig. 2, according to a village space coordinate system, a position coordinate of each fire-fighting arm support (i.e., the fire-extinguishing device) may be determined, and when a fire occurs, the position coordinate of each fire-fighting arm support, a position coordinate of a fire detection sensor that sends an alarm signal, and a wind speed and a wind direction collected by a wind speed and direction indicator may be reported to a fire early-warning system, and the fire early-warning system determines a fire-extinguishing scheme.
For example, each of the at least one fire arm support may be a multi-section foldable arm support, or a fire arm support combining a telescopic arm support and a foldable arm support. The fire-fighting arm support can comprise a first arm section and a second arm section, and the fire-fighting arm support can be a multi-section folding arm support and can also be a fire-fighting arm support with a telescopic arm section and a folding arm section combined together. That is, the first arm section may be a folding arm section or a telescopic arm section, and the second arm section may be a folding arm section or a telescopic arm section. The first arm section and the second arm section may each include at least one arm section, and the at least one arm section may further include arm sections of different types.
It should be noted that the fire-fighting boom can be installed at a fixed position in the monitoring area, so that the fire-fighting boom can timely participate in fire extinguishing when a fire occurs.
For example, in order to establish the flame retardant belt as quickly as possible, the step 102 may include the following steps 102b:
and 102b, determining the number of the second target devices according to the area size of the second area.
Illustratively, the larger the area of the second zone, the greater the number of fire suppression devices that need to spray fire suppressant onto the zone in order to be able to build the fire retardant zone as quickly as possible.
In a possible implementation manner, the calculation formula of the prevention and control distance of the fire extinguishing apparatus, which is influenced by the wind speed, can be the following formula one:
D defend (= D-D:. Alpha.). Cos θ (formula one)
Wherein, D is defend The distance for preventing and controlling the fire extinguishing equipment; d is the maximum distance of the fire extinguishing equipment for spraying the fire extinguishing agent, alpha is a wind speed coefficient, and theta is an included angle between a connecting line of the fire extinguishing equipment and a fire passing area and a wind direction.
It will be appreciated that the faster the wind speed, the greater the effect on the coverage of the extinguishing agent sprayed by the extinguishing device, and therefore the wind speed and wind direction effects need to be taken into account when determining the control distance for each extinguishing device. Meanwhile, the same fire extinguishing apparatus can spray fire extinguishing agent only for one area, and thus, fire extinguishing apparatuses corresponding to the first area and the second area need to be calculated respectively.
And 103, controlling the target equipment to spray fire extinguishing agent to the control area.
Illustratively, the fire extinguishing agent may include: gaseous extinguishing agents, water and water-based extinguishing agents, foam extinguishing agents, solid extinguishing agents, and the like.
For example, after the first area and the second area are determined, and the first target device spraying the fire extinguishing agent to the first area and the second target device spraying the fire extinguishing agent to the second area are determined, the first target device may be controlled to spray the fire extinguishing agent to the first area, and the second target device may be controlled to spray the fire extinguishing agent to the second area.
Illustratively, the step 103 may include the following steps 103a:
103a, controlling the first target device to spray fire extinguishing agent to the first area, and controlling the second target device to spray fire extinguishing agent to the second area.
Illustratively, when the fire early warning system detects that a fire possibly exists, the control center determines the fire point position by comparing the monitoring systems. The control system distributes fire extinguishing equipment participating in fire extinguishing and fire extinguishing equipment preventing and controlling fire spreading by comprehensively analyzing the influence of wind direction and wind speed on fire. And the control system determines a prevention and control range according to the actual prevention and control distance of each fire extinguishing apparatus, and determines the fire extinguishing apparatus participating in fire extinguishing according to whether the first area and the second area are overlapped with the prevention and control range of each fire extinguishing apparatus.
In one possible implementation manner, under the condition that the wind speed of the current environment is smaller than a preset threshold value, the first target equipment is controlled to spray the fire extinguishing agent to the first area, and the second target equipment is controlled to start and enter a standby state so as to prepare for spraying the fire extinguishing agent to the second area; and under the condition that the wind speed of the current environment is greater than or equal to a preset threshold value, controlling the first target equipment to spray fire extinguishing agent to the first area, and controlling the second target equipment to spray fire extinguishing agent to the second area.
Specifically, under the condition that the fire extinguishing apparatus is a fire arm support, controlling the second target apparatus to start and enter a standby state includes: and controlling the boom of the second target device to be unfolded, and controlling the fire extinguishing agent spraying device on the boom to face the second area.
For example, referring to fig. 2, as shown in fig. 3, after the position coordinates of each fire arm support and the position coordinates of a fire point are determined according to a spatial coordinate system, the prevention and control range of each fire arm support is determined according to the prevention and control distance of each fire arm support obtained by the first formula, and after the actual position information is compared, the fire arm supports (i.e., the target devices) participating in fire fighting are determined. Specifically, if the ignition point is located in the prevention and control range of a certain arm support, the arm support is unfolded, and the water pump is started and sprays water to extinguish fire; if the distance between the ignition point and the arm support exceeds the prevention and control range but exceeds within 30 percent, the arm support is unfolded, the water pump is not started, and the arm support is controlled to be in a standby state to deal with the possible fire spreading condition at any time; if the distance between the ignition point and the arm support exceeds the prevention and control range and exceeds 30%, the arm support part is unfolded, the water pump is not started, and the arm support is controlled to be in a standby state.
It should be noted that the control flow diagram of the fire arm support shown in fig. 3 describes a control method of a fire extinguishing apparatus by taking an ignition point (the first area) as an example, and for the second area, the control method may be referred to control the fire arm support.
According to the fire extinguishing method provided by the embodiment of the invention, when a fire disaster occurs, the fire passing area can be determined according to the information acquired by the fire detection sensor, and the fire spreading area can be determined according to the wind speed and the wind direction of the current environment. And then, determining fire extinguishing equipment participating in fire extinguishing according to the prevention and control range of each fire extinguishing equipment, and respectively spraying fire extinguishing agents to the fire passing area and the fire spreading area. According to the fire extinguishing method provided by the embodiment of the invention, the fire extinguishing agent is sprayed to the fire passing area, and meanwhile, the flame retardant zone can be established, so that the fire extinguishing efficiency is greatly improved.
It should be noted that, in the embodiment of the present invention, the fire extinguishing method provided in the embodiment of the present invention is described in detail by taking an outdoor village scene as an example, but the fire extinguishing method is not limited to be only used in an outdoor scene, and the fire extinguishing method may also be applied to an indoor scene, for example, an indoor scene such as a warehouse.
