Referring to fig. 1, the smoke detection system includes a processor 100 and a memory 200, and the memory 200 stores a smoke detection program. The smoke detection program is configured to be executed by the processor 100, and the processor 100 executes the smoke detection program to realize the smoke detection method, so that the smoke detection system can be applied to large indoor places, such as airport halls, train station waiting halls, theaters, gymnasiums and the like, can automatically identify and lock areas where smoke is generated by burning of articles, can be used as a smoke detection system, can detect smoke generated by smoke, find smoking behaviors in time, quickly lock smokers, effectively reduce smoking behaviors and provide a brand-new smoke control means for managers.
Referring to fig. 2, the smoke detection method includes:
step S11: detecting the components of the air to be detected in the area to be detected;
step S12: judging whether the components of the air to be detected comprise preset components or not; if the air to be detected comprises preset components, executing step S13; otherwise, continue to execute S11;
step S13: tracking an initial location of smoke generation in an area to be detected;
step S14: locating an initial location of said aerosol generation;
step S15: an alarm is issued.
In this embodiment, the area to be detected is a monitoring range of the smoke detection system, and by acquiring the air to be detected in the area to be detected and detecting components in the air to be detected, it is determined whether preset components exist, specifically, the preset components may be chemical substances generated after combustion of an article, including but not limited to carbon monoxide, chlorine, phosgene, ammonia, sulfur dioxide, liquefied petroleum gas, nicotine and tar; specifically, the initial position of the smoke generation is the position of the article when the article burns, the article burns to generate smoke, and the position of the burning object displayed in the smoke detection system is the initial position of the smoke generation. Taking a cigarette as an example, by detecting the content of nicotine and/or tar in the region to be detected, if the content of nicotine and/or tar exists, it can be known that someone is smoking in the region to be detected; and detecting the initial position of the cigarette which is ignited by the smoker in the area to be detected and generates the smoke, narrowing the monitoring range according to the detected initial position of the cigarette which generates the smoke, locking the smoking object, performing locking monitoring and giving an alarm to the smoker in the smoking area. Specifically, the detection of the preset components is a step of detecting components in the air so as to judge whether the combustion products exist or not; the initial position that the locking smog produced can carry out the surveillance video to the initial position that the smog that detects produced through the camera to after the initial position that detects the smog and produce the alarm, monitoring personnel can lock the initial position that produces the smog and produce, find the source of article burning.
Preferably, the smoke detection system maintains a sleep state to save energy consumption when the concentration of the air to be detected is normal, and in particular, before step S11, the method further includes:
step S21: detecting whether the concentration of the air to be detected reaches an early warning threshold value; if the concentration of the air to be detected reaches the early warning threshold value, executing step S22: otherwise, returning to step S21;
step S22: and detecting the components of the air to be detected in the area to be detected.
Specifically, the air concentration of the area to be detected is generally constant, and when smoke is generated in the area to be detected, the smoke detection system is awakened because the smoke can increase the air concentration of the area to be detected, and the preset components are detected by sucking the air to be detected.
Preferably, in step S12, the step of determining whether the air to be detected includes preset components specifically includes:
step S31: detecting whether the content of a preset component in the air to be detected exceeds a preset component threshold value or not; if the preset components in the air to be detected exceed the preset component threshold value, executing the step S32, otherwise, returning to the step S11;
step S32: and judging that the area to be detected comprises the ignition objects.
Preferably, referring to fig. 3, when the smoke detection system is used to detect whether there is smoking in the area to be detected, in step S12, the smoke detection method includes:
step S41: detecting whether the tar content in the air to be detected exceeds a preset tar threshold value; if the tar content in the air to be detected exceeds a preset tar threshold, executing step S42: otherwise, returning to step S11;
step S42: judging whether the nicotine content in the air to be detected exceeds a preset nicotine threshold value or not; if the nicotine content in the air to be detected exceeds a preset nicotine threshold value, executing step S43; otherwise, returning to continue the step S11;
step S43: and judging that the lighted cigarette exists in the area to be detected.
In this embodiment, the air to be detected is subjected to data collection and further analysis processing. The ignition object to be detected is a lighted cigarette, and whether tar and nicotine components are contained in the air to be detected or not is mainly judged so as to judge whether the concentration increase in the air to be detected is caused by smoking the cigarette or not. If nicotine and tar are included at the same time, smoking behavior of the cigarette can be determined. If tar and nicotine components are not simultaneously detected in the air to be detected, the system is judged to be not smoking smoke, and no further action is taken.
In addition, referring to fig. 4, when the location of the smoke source is located, step S13 includes:
step S51: detecting heat information of the area to be detected;
step S52: judging whether an area with heat information exceeding a heat threshold exists in the area to be detected; if the area to be detected has an area with heat information exceeding a heat threshold, executing step S53; otherwise, continue to step S51;
step S53: the area exceeding the thermal threshold is identified as the initial location of smoke generation.
Specifically, the heat information monitoring can be obtained by detecting an infrared thermal sensor of the camera. The detection range of the area to be detected can be places with larger space ranges such as an airport hall, a railway station waiting hall and a stadium, and the camera is arranged in the places such as the airport hall, the railway station waiting hall and the stadium to acquire pictures of the places. Specifically, the area to be detected can be divided into a plurality of different sub-areas, and when the area with the heat information exceeding the heat threshold is detected, the sub-area with the heat information exceeding the heat threshold is set as the initial position of smoke generation, so that the initial position of smoke generation can be monitored in an amplification manner. Taking smoking behavior as an example, ignition of a cigarette can cause the temperature of air near the cigarette to rise, the specific position of a smoker in the area to be detected can be found by detecting the heat information of the area to be detected, and the position of the smoker is marked as a smoking area, so that the smoke detection system can perform locking detection on the smoking area, and a monitoring worker can find the smoker.
Preferably, referring to fig. 5, in an embodiment, in step S52, the method for determining the initial position of smoke generation further includes:
step S61: accumulating the heat duration time that the heat information of the area to be detected exceeds the heat threshold value;
step S62: judging whether the heat duration time exceeds a preset first time or not; if the heat duration time exceeds the preset first time, executing the step S53, otherwise, returning to continue executing the step S51;
step S63: the area exceeding the thermal threshold is identified as the initial location of smoke generation.
Specifically, the burning of smog can continuously give off the heat for temperature around rises, through detecting the temperature, can judge smog source position. For example, when the cigarette is lit, the temperature is emitted for a period of time, and further, when the heat duration time when the accumulated heat information exceeds the heat threshold exceeds a preset first time, it can be determined that someone is smoking in the area, and the area is identified as the initial position of smoke generation.
Preferably, referring to fig. 6, in another embodiment, in step S52, the method for determining the location of the smoke source further includes:
step S71: if the area to be detected has an area with heat information exceeding a heat threshold value, marking the area as a possible initial position;
step S72: the number of times the region in which the cumulative thermal information exceeds the thermal threshold is marked as a possible initial position;
step S73: judging whether the times that the same area is marked as the possible initial position within the preset second time is greater than the preset times or not; if the number of times that the same area is marked as the possible initial position within the preset second time is greater than the preset number of times, performing step S64, otherwise, continuing to perform step S61;
step S74: identifying the possible initial location as an initial location of smoke generation;
specifically, the initial position may be a region in which the infrared thermal sensor detects that the time at which the heat information exceeds the heat threshold is less than the first time in the region to be detected. A smoker may put down after smoking a cigarette so that the infrared thermal sensor cannot detect the temperature and thus cannot determine the smoking area. Therefore, in the second time, if the possible initial position of the heat information exceeding the heat threshold value appears in the area to be detected for multiple times, the area is directly judged as the initial position of the smoke generation.
Preferably, step S14 includes:
step S81: acquiring an image of the area to be detected;
step S82: and acquiring an image of the initial position generated by the smoke according to the corresponding coordinate of the initial position generated by the smoke in the area to be detected.
