Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, with reference to fig. 1, a fire alarm method according to an embodiment of the present invention includes the following steps:
step S101: and detecting target environment data in the designated area in real time, wherein the target environment data comprises target color data, target temperature data, target sound data, target spreading speed data and target duration time data.
In the detection range of the fire alarm device (including indoor and outdoor designated areas), various environmental data are continuously detected 24 hours a day, so that a basis is provided for accurately judging the fire. The flame is colored when fire occurs, and the color of the flame generated by different combustibles is different, so that the temperature and vibration state of the flame are different. Therefore, if only the same or similar color as that of the flame is detected, it can be primarily judged that the fire is occurring, but the fire cannot be determined, and further judgment of the temperature and vibration state is required to make an accurate judgment.
Optionally, the target environmental data further includes environmental data such as target ultraviolet intensity, target environmental humidity, target environmental oxygen concentration, etc., and if the target environmental data is abnormal, it may be primarily determined that a fire disaster occurs, and the abnormal environmental state indicates that any one of the following occurs: the target ambient temperature is greater than or equal to a preset ambient temperature, the target ambient humidity is less than or equal to a preset ambient humidity, the target ultraviolet light intensity is greater than or equal to a preset ultraviolet light intensity, and the target ambient oxygen concentration is less than or equal to a preset ambient oxygen concentration.
Step S102: and judging whether the target flame color generated by the corresponding flame in the appointed area is detected.
The target flame color is a flame color generated by various combustibles during combustion, and can be obtained by taking a picture through a camera, and when the target flame color is detected, the following steps are further needed to judge whether a fire disaster has occurred or not.
Step S103: if the target flame color generated by the corresponding flame in the appointed area is detected, acquiring the target flame temperature corresponding to the target flame color, and further judging whether the target flame temperature is larger than or equal to a preset temperature threshold value.
Wherein, the flame is necessary or generated after the fire disaster happens, and the temperature of the flame is far higher than the normal environment temperature, but the flame is not necessarily generated when the temperature reaches the preset temperature threshold (flame temperature), and other conditions of generating high temperature exist, such as the condition that the temperature generated by cooking in an electromagnetic oven is very high, the temperature of frying oil in a kitchen also reaches the very high temperature, but the fire disaster does not happen.
Step S104: if the target flame temperature is greater than or equal to a preset temperature threshold, further judging whether the target flame vibration sound generated by corresponding flame is detected in the designated area.
Wherein, every thing that moves has its fixed vibration sound, and the vibration sound of flame is different with other things, and the flame has its fixed vibration frequency, can distinguish other vibration frequencies, and this is the basis of judging the flame that produces.
Step S105: if the target flame vibration sound generated by corresponding flame is detected in the designated area, further judging whether the target flame vibration sound is detected in the designated area and is in a spreading state of an expanded area.
However, if a flame is generated, a target flame vibration sound corresponding to the flame is detected in the specified area, and a fire is not necessarily generated, and normal artificial fire cooking or artificial smoke ignition by using a lighter is possible, so that further judgment is required. When the target flame vibration sound is detected to be in the spreading state of the expansion area, the flame generated by normal artificial fire cooking or smoking is not shown, and the fire disaster actually occurs. Alternatively, even if the target flame vibration sound is not in an extended area of spread, the alarm is given for a long duration, and the duration of flame generation is an important fire judgment basis, so that the fire is likely not to spread, but the valuable articles are burned out in one place for a long time, which causes a significant loss.
Step S106: if the target flame vibration sound is detected to be in the spreading state of the expanding area in the appointed area, judging that a fire accident occurs in the appointed area, and performing relevant alarm processing. The alarm processing is not limited to the scope of the present embodiment, and any alarm processing method that is advantageous for fire rescue can be used as the alarm processing method of the present embodiment.
In this embodiment, optionally, the determining that a fire accident occurs in the specified area, and performing alarm processing includes:
first, continuing to detect the target environmental data in the specified range in real time, and further judging whether the target duration of the target flame vibration sound in the specified area is longer than a preset duration. Some of these fires are only mild, burn out in a short time, and do not spread elsewhere, which is a low risk fire. However, the fire in some fires is very large and quickly spreads to other places, resulting in large-area disasters.
Secondly, if the target duration of the target flame vibration sound in the appointed area is longer than the preset duration, judging that the fire accident is an appointed-level fire accident, and shooting a target fire scene video in the appointed area.
The target fire scene video within the appointed range is shot, so that related departments can intuitively and vividly know the condition of the fire, and the rapid expansion of fire rescue work is facilitated.
Thirdly, acquiring target position coordinates corresponding to the appointed area, and sending the target position coordinates and the target fire scene video to institutions including fire departments and resident authorities for processing. Therefore, residents can escape in time, and firefighters can also extinguish fire and rescue in time.
In this embodiment, optionally, the determining whether the target flame color generated by the flame corresponding to the occurrence of the flame in the specified area is detected includes:
first, all the environmental colors appearing in the designated area are acquired, wherein all the environmental colors comprise the colors of all objects in the designated area, and the colors of different objects are different from the colors of flames.
Secondly, comparing all the environmental colors with various pre-stored flame colors in a pre-stored flame color database, and judging whether target contrast colors which are the same as or similar to the pre-stored flame colors exist in all the environmental colors. The various pre-stored flame colors in the pre-stored flame color database are flame colors generated when various combustible matters collected in advance are combusted, and the flame colors comprise smoke colors generated by the flames and normal shapes.
Thirdly, if the target contrast color which is the same as or similar to the pre-stored flame color exists in all the environmental colors, whether the target contrast color is in a motion state is further judged. Wherein when a flame is generated, the flame is necessarily moving and cannot be stationary, so that it is necessary to determine whether the target contrast color is a flame color by judging whether the target contrast color is in a moving state.
Fourth, if the target contrast color is in a motion state, determining that the target flame color generated by corresponding flame in the designated area is detected.
In this embodiment, optionally, the further determining whether the target flame vibration sound generated by the flame correspondence is detected in the specified area includes:
first, a target air vibration frequency in the designated area is further detected, wherein when a flame is generated, the air vibration is inevitably driven, and the frequency of the flame vibration has an inherent range.
And secondly, judging whether the target air vibration frequency is in a vibration frequency range generated by corresponding flame.
Thirdly, if the target air vibration frequency is within a vibration frequency range generated by corresponding flame, judging that the target flame vibration sound generated by corresponding flame is detected in the designated area.
In this embodiment, optionally, the further determining whether the target flame vibration sound is detected in the specified region in a spread state of an enlarged region includes:
first, the target smoke concentration in the appointed area is obtained, whether the target smoke concentration is in an increased state is further judged, the increase of the target smoke concentration indicates that the fire is continuously expanded, and the fire is not normally generated by people.
Second, if the target smoke concentration is in an increased state, further acquiring the target oxygen concentration in the designated area, and further judging whether the target oxygen concentration is in a decreased state, wherein more oxygen is consumed after the fire is increased, and the oxygen concentration in the designated area is necessarily decreased.
Third, if the target oxygen concentration is in a reduced state, it is determined that the target flame vibration sound is detected in the specified region in a spread state of an enlarged region.
In this embodiment, optionally, the determining that a fire accident occurs in the specified area and performing related alarm processing includes:
first, according to the target flame color and the target flame temperature, the type of the target object corresponding to the fire disaster is obtained, because the fire disaster conditions generated by different objects are different, and the dangerous grade coefficients are different. For example, flammable and explosive objects and chairs differ in their paper and the consequences of combustion are different.
And secondly, generating target fire type and target risk level data according to the target object type, wherein the target fire type and the target risk level data are used for reference of firefighters, and the firefighters can take relevant rescue measures according to the target fire type and the target risk level data.
Thirdly, acquiring target position coordinates corresponding to the appointed area, and sending the target position coordinates, the target fire type and the target hazard level data to an appointed address for processing. Among them, it is very important to acquire a fire place (target position coordinates) and time, so that firefighters can quickly arrive at the fire place.
In this embodiment, optionally, the acquiring the target position coordinate corresponding to the specified area, and sending the target position coordinate, the target fire type, and the target hazard class data to a specified address for processing includes:
first, the fire extinguishing device is started to extinguish fire in the appointed area. Alternatively, the fire is extinguished by spraying water, or spraying powder.
Secondly, sending a state video corresponding to the current fire to the designated address once every preset time period until the fire is ended. This is in order to communicate the fire situation to the relevant departments in real time, which is advantageous for firefighters to make the most appropriate rescue mode.
