The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

The intelligent fire alarm method provided by the embodiment of the invention is applied to one or more terminals. The intelligent fire alarm method can also be applied to a hardware environment consisting of a terminal and a server connected with the terminal through a network. Networks include, but are not limited to: a wide area network, a metropolitan area network, or a local area network. The intelligent fire alarm method of the embodiment of the invention can be executed by a server or a terminal; or may be performed by both the server and the terminal.

For another example, the method provided by the present invention may also be operated on a server or other devices in the form of a Software Development Kit (SDK), an interface of the intelligent fire alarm function is provided in the form of an SDK, and the terminal or other devices may implement hand tracking through the provided interface.

Example one

Fig. 1 is a flowchart of an intelligent fire alarm method according to an embodiment of the present invention. The execution sequence in the flowchart may be changed and some steps may be omitted according to different requirements.

And S11, receiving a fire alarm command.

In some embodiments, a fire APP (hereinafter, referred to as "fire APP") may be installed in the terminal in advance, and the fire APP may be used to detect a fire risk, obtain fire information, receive a fire alarm command, and the like. When a user finds that fire danger exists or thinks that fire alarm is necessary, a fire alarm instruction can be manually input through a fire APP of the terminal. The user-entered fire alarm instruction may include a combination of one or more of the following: inputting preset text information, for example, inputting the text "fire"; inputting preset voice information, for example, inputting voice 'alarm'; and touching a preset button or icon of the fire APP.

In some embodiments, at least one sensor may be integrated into the terminal in advance, the sensor may be a thermal sensor such as a thermistor or the like, or a gas sensor detecting a gas such as carbon monoxide, carbon dioxide, hydrogen or NOx which may indicate a fire, and the signal detected by the thermal sensor and/or the gas sensor may be used by the terminal to determine whether a fire is present in the environment. That is, the terminal may determine whether to trigger a fire alarm command according to the signal detected by the at least one sensor and a preset alarm condition, and when it is determined that the signal detected by the at least one sensor satisfies the preset alarm condition, the terminal automatically triggers the fire alarm command.

The preset alarm condition is a preset alarm condition, and may include, but is not limited to: when the temperature in the air is detected to exceed a preset first temperature threshold value and the input operation of a user is detected within a preset first time period, determining that the preset alarm condition is met; when the temperature in the air is detected to exceed a preset second temperature threshold value, determining that the preset alarm condition is met; when the gas concentration in the air is detected to exceed a preset first gas concentration threshold value and the input operation of a user is detected within a preset second time period, determining that the preset alarm condition is met; and when the gas concentration in the air is detected to exceed a preset second gas concentration threshold value, determining that the preset alarm condition is met. Wherein the preset first temperature threshold is smaller than the preset second temperature threshold, and the preset first gas concentration threshold is smaller than the preset second gas concentration threshold. The preset first time period may be the same as or different from the preset second time period.

The preset first temperature threshold (for example, 20 degrees) is set to be smaller than the preset second temperature threshold (for example, 50 degrees) and the preset first time period, so that when the temperature in the air exceeds the preset first temperature threshold but does not exceed the preset second temperature threshold, the time is buffered for the user, and the user can decide whether to input an alarm instruction or when to input the alarm instruction according to the situation of the fire scene, for example, when the range of the fire scene is small and a convenient fire extinguishing device is arranged around the fire scene, and the user can select not to trigger the alarm instruction when controlling or extinguishing the fire in the preset first time period. Meanwhile, when the temperature in the air is within the preset first time period (for example, 1 minute), the preset first temperature threshold value is suddenly increased to the preset second temperature threshold value, and the user does not have time or cannot input the operation, an alarm instruction can be automatically and quickly triggered. The purpose of setting the preset first gas concentration threshold (e.g., 20%) to be smaller than the preset second gas concentration threshold (e.g., 30%) and the preset second time period (e.g., 30 seconds) is the same as the above temperature, and detailed description thereof is omitted here.

The terminal receives the fire alarm instruction when detecting the fire alarm instruction input by the user and/or when detecting that the preset alarm condition is met.

And S12, responding to the fire alarm command, and acquiring the sensing information of a plurality of sensors.

In some embodiments, the sensed information may include, but is not limited to: the burning value, the wind direction value, the smoke concentration value, the temperature value, the flame value, the heartbeat value, the blood pressure value, the breathing frequency and the like of the combustible materials at the fire scene.

In some embodiments, the sensors may be built in the terminal or may be in communication connection with the terminal, and the sensing information of the sensors may be obtained by:

1) the method comprises the steps of obtaining signals detected by at least one sensor built in the terminal through reading;

2) the terminal is used for receiving an external device in communication connection with the terminal.

The external devices may include, but are not limited to: smoke sensor, position sensor, temperature sensor, humidity sensor and photosensitive sensor. Preferably, the external device is a smoke sensor, when the concentration of smoke in the air is 0.1mg/m³The smoke sensor can respond quickly, and the response time is less than 30 seconds.

And S13, judging whether the fire alarm instruction is effective or not according to the sensing information.

As an alternative embodiment, the determining whether the fire alarm command is valid according to the sensing information may include:

The combustion value and the wind direction value with different units can be normalized to the range of (0,1) through a preset function, then whether the current environment of the terminal is really conflagration occurrence or not is further judged by combining the combustion value of combustible materials and the current wind direction value, if the conflagration occurrence and the current wind direction value have an enlarged trend, the fire alarm instruction is determined to be effective, and the condition that the user unconsciously starts the fire APP to trigger the fire alarm instruction can be avoided.

As another alternative, the determining whether the fire alarm command is valid according to the sensing information may include:

judging whether the minimum value is larger than a preset physiological parameter threshold value, wherein the preset physiological parameter threshold value is a preset physiological parameter and is a physiological parameter critical value representing that the user is in an unconscious state;

Whether the user is in the unconscious state or not is further judged by combining physiological parameters (such as heartbeat, blood pressure and breathing frequency) of the user, and if the user is in the unconscious state, the fire alarm instruction can be determined to be effective.

When it is determined that the fire alarm command is valid, performing step S14; when it is determined that the fire alarm command is invalid, step S15 is performed.

And S14, acquiring a fire video of a fire scene, and sending a fire alarm instruction carrying the fire video and the sensing information to an alarm terminal.

In some embodiments, a preset camera can be used for shooting a real-time fire video of a fire scene, the camera can be used for shooting the fire scene in 360 degrees without dead angles, the camera can be in real-time communication with the terminal, and the terminal can acquire the fire video shot by the camera in real time and send a fire alarm instruction carrying the fire video and the sensing information to an alarm terminal. The alarm terminal may be an alarm platform center, typically a 119 alarm center.

And S15, outputting a prompt of fire self-rescue measures to guide the user to carry out self-rescue.

When the fire alarm instruction is determined to be invalid, a prompt of fire self-rescue measures can be output, for example, a preset voice or a preset fire-fighting learning video is input to guide a user how to prevent excessive smoke from being inhaled, how to use fire-extinguishing equipment, how to escape and the like, so that the user can carry out self-rescue before rescuers arrive, and more survival opportunities are strived for. In addition, when the fire alarm instruction is determined to be invalid, the fire alarm instruction is not sent to the alarm terminal, and waste of fire fighting resources can be reduced.

And S16, acquiring the time when the fire alarm instruction is sent to the alarm terminal.

And after the terminal sends the fire alarm instruction carrying the fire video and the sensing information to an alarm terminal, acquiring the current sending time.

S17, if the sending time is determined to be in the daytime, acquiring road condition information of the road in real time and sending the optimal path plan to the alarm terminal; and if the sending time is determined to be at night, obtaining street lamp information of the road in real time and sending the optimal path plan to the alarm terminal.

Generally, if a fire alarm command is sent in the daytime, although enough rescue workers are allocated on the side of the alarm terminal, the pedestrian flow and the traffic flow on the road are large in the daytime, and related people cannot timely arrive at the fire scene due to road congestion. However, if the fire alarm command is transmitted at night, it is difficult to allocate a large number of executives to perform rescue work at the first time due to the inconvenience at night, insufficient allocation of rescuers, and the like, and thus the terminal may perform different operations according to the transmission time of the fire alarm command in order to adapt to various situations.

If the sending time of the fire alarm instruction is in the daytime, the terminal can acquire real-time road condition information between the terminal and the alarm terminal, and the road condition information comprises: the quality information of the road and the congestion information of the road are obtained, and the road with good road surface quality and less congestion is used as an optimal path plan, so that rescuers at the alarm terminal can arrive at a fire scene for rescue at the highest speed in time, and casualties and property loss are reduced. If the sending time of the fire alarm instruction is at night and an additional external factor, namely brightness, needs to be considered, the terminal can acquire the lighting facilities and can be used as an optimal path plan in a normally working road section, so that the rescuers at the alarm terminal can arrive at the fire scene for rescue at the highest speed in time, and the rescuers can be ensured to drive safely in the journey to the fire scene.

As an optional embodiment, when receiving the fire alarm command, the method may further include: outputting preset prompting information to prompt a user to input the number of people trapped in a fire scene and the reason of fire occurrence; and sending the number of trapped people and the fire occurrence reason input by the user to the alarm terminal.

The preset prompting information can be used for prompting in a text mode or a voice mode, a user inputs the number of people trapped in a fire scene and the reason of fire (such as natural combustible materials, artificial longitudinal fire, line aging and the like) according to the preset prompting information, and sends the number of people trapped in the fire scene, the reason of fire, the fire video and the fire alarm instruction of the sensing information to the alarm terminal after receiving the prompting information input by the user, so that the rescuers at the alarm terminal can obtain more detailed and accurate fire information, and the rescuers at the alarm terminal can make an accurate fire rescue decision in time.

As an alternative embodiment, when it is determined that the fire alarm command is valid, the method may further include: determining the fire level of a fire scene; judging whether the fire level is greater than a preset fire level threshold value or not; and when the fire level is determined to be greater than or equal to the preset fire level threshold value, sending fire alarm information to a terminal of a manager to which the user house belongs.

The fire alarm information may include: the terminal comprises a current geographic position, a fire level and a fire video of the fire scene. The preset fire grade threshold value is a preset fire grade and is a critical value for distinguishing a fire grade of a fire scene into a high grade or a low grade. When the fire level of the fire scene is greater than or equal to the preset fire level threshold, determining that the fire level is a high level, which indicates that the fire of the fire scene is serious, the smoke concentration of the fire scene is high, the temperature is high, the flame radiation is large, the fire hazard degree is high, and the destructive power is strong; and when the fire grade of the fire scene is smaller than the preset fire grade threshold value, determining the fire grade as a low grade, which indicates that the smoke concentration, the temperature and the flame radiation of the fire scene are low, the fire hazard degree is low, and the destructive power is weak.

In some embodiments, the determining a fire classification of the fire scene may specifically include: carrying out weighted summation on the smoke concentration value, the temperature value and the flame value according to a preset calculation rule to obtain the fire level of the fire scene, wherein the preset calculation rule is as follows: yi ═ e^xi-e^-xi)/(e^xi+e^-xi) S is a 1| y1| + a 2| y2| + a 3| y3|, and a1+ a2+ a3 ═ 1, xi represents the smoke concentration value, temperature value, and flame value, a1 is a weight value set in advance for the smoke concentration value, a2 is a weight value set in advance for the temperature value, a3 is a weight value set in advance for the flame value, and S is the calculated fire level. yi ═ e^xi-e-^xi)/(e^xi+e-^xi) The purpose of (a) is to normalize the smoke concentration value, temperature value and flame value to within a range of (-1,1), and further to within a range of (0,1) by taking absolute values.

When the fire level is determined to be a high level, namely under the condition that the fire on the fire scene is determined to be serious, the fire alarm information is sent to the terminal of the management personnel belonging to the house, so that the management personnel belonging to the house can timely carry out early rescue work before the rescue personnel at the alarm terminal arrive at the fire scene, all rescue opportunities are strived for as much as possible, and the rescue personnel at the alarm terminal are prevented from giving an alarm in time and delaying rescue.

As an optional embodiment, after the acquiring the fire video of the fire scene, the method may further include: analyzing the reason of the fire according to the fire video, and determining the type of the fire; and controlling a corresponding fire extinguishing device to extinguish the fire according to the fire type.

In some embodiments, the terminal may pre-store a plurality of fire types and corresponding fire suppression devices. The fire type may be set according to "fire classification" released by national standards revision. The fire extinguishing device can realize network connection through the Internet of things and can be intelligently controlled.

The analyzing the cause of the fire according to the fire video specifically comprises: extracting each frame image in the video; judging whether a preset substance appears in each frame image; when it is determined that a preset material is present, a fire type is determined according to the preset material. For example, when the fire disaster video is judged to have fire disasters such as wood, cotton, wool, hemp, paper and the like, the fire disaster type is determined to be a type A fire disaster; judging whether fires such as gasoline, kerosene, crude oil, methanol, ethanol, asphalt, paraffin and the like appear in the fire video, and determining the type of the fire as a B-type fire; judging whether a potassium, sodium, magnesium, aluminum magnesium alloy fire and the like appear in the fire video, and determining the fire type as a D-type fire; and when the cooking appliances appear in the fire video, determining that the fire type is the F-type fire.

For example, when the type of fire is determined to be a class E fire, i.e., a live fire, the knife switch may be controlled to automatically power off, thereby cutting off the line power in the house and controlling further deterioration of the fire. For another example, when it is determined that the type of the fire is a class F fire, that is, a fire of cooking materials in the cooking appliance, the cooking appliance may be controlled to be automatically turned off.

According to the fire video, the fire type is determined and the corresponding fire extinguishing device is controlled to extinguish the fire, so that the input operation of a user can be effectively reduced, particularly, when the user is in the situation that the consciousness is fuzzy and the user can not input any operation, the fire type can be automatically determined according to the fire video, and then the corresponding fire extinguishing device is controlled to extinguish the fire, so that the source of fire occurrence is effectively blocked, and the fire behavior is reduced.

In summary, the intelligent fire alarm method of the present invention implements quick alarm through the fire APP and automatic alarm through detecting whether a preset alarm condition is met, and when receiving an alarm instruction, first obtains sensing information of the current environment of the terminal, and further determines that the fire alarm instruction is valid according to the sensing information, and then obtains a fire video of a fire scene, and sends the fire alarm instruction carrying the fire video and the sensing information to the alarm terminal. The method can avoid false alarm, provide more detailed and accurate fire information during alarm, and facilitate the rescuers at the alarm terminal to make accurate fire rescue decisions in time. And meanwhile, the time of the fire alarm instruction sent to the alarm terminal is obtained, and different optimal path plans are selected and provided for the quotation terminal according to the sending time, so that rescuers at the alarm terminal can arrive at a fire scene at the highest speed in time for rescue.

And secondly, when the fire alarm instruction is determined to be invalid, outputting a prompt of a fire self-rescue measure to guide the user to carry out self-rescue, so that the user can carry out self-rescue before rescuers arrive to strive for more survival opportunities, and when the fire alarm instruction is determined to be invalid, the fire alarm instruction is not sent to the alarm terminal, and the waste of fire-fighting resources is reduced. In addition, the fire type is determined according to the reason of the fire video analysis; according to the extinguishing device that the fire type control corresponds puts out a fire, can block the source that the conflagration took place, reduces the intensity of a fire.
