Detailed Description
The present application is described in further detail below with reference to the accompanying drawings.
In modern cities, many people do not understand the common sense of home safety to cause fire accidents, and the main reason of home fire is that because of paralytic significance, no preventive measures are actively taken, so that in the home, the smoke alarm can be installed to monitor the smoke concentration in the home at all times, thereby reducing the influence caused by the fire.
The smoke alarm can prevent fire by monitoring the smoke concentration, the smoke at the beginning of the fire can be accumulated under the indoor ceiling, the smoke detector can monitor and detect the existence of the smoke in real time, and the environment is periodically detected at intervals. When the smoke concentration entering the smoke detector reaches a threshold value, radioactive substances in the ionic smoke sensor inside the smoke alarm can generate current, and when smoke particles in the smoke enter the sensor, the current can be disturbed, so that the alarm sounds.
Since a total monitoring room is arranged in each cell, the total monitoring room comprises a plurality of cameras and smoke alarms, wherein the cameras can monitor the whole cell. And each household people room, the public corridor and the general monitoring room are provided with corresponding smoke alarms. When the smoke alarm in the resident room gives out alarm sound, the smoke alarm in the general monitoring room can give out alarm sound as well, and unnecessary panic can be caused.
In order to enable the smoke alarm in a resident room and the smoke alarm of the master monitoring alarm to accurately send out alarm sounds, so that damage caused by fire is reduced. Referring to fig. 1, the method comprises the steps of:
s100, acquiring smoke concentration information.
The smoke concentration information is characterized by being the current indoor smoke concentration information, when smoke exists in the room, the smoke is concentrated on the ceiling, and then enters the smoke alarm to be received by the smoke detector, so that the current smoke concentration information can be obtained. The smoke concentration information comprises a smoke concentration signal and a change concentration, wherein the smoke concentration signal is characterized as a current smoke concentration signal, and the change concentration is characterized as a change concentration of smoke in a preset time.
Because there may be many people in the room to smoke, the indoor smoke concentration is too big, and then can make the smoke detector detect, can make the smoke alarm send out alarm sound, therefore, when obtaining smoke concentration information, need to judge whether indoor smoke concentration is because of catching fire according to smoke concentration information. Judging whether the room catches fire or not according to the smoke concentration information,
s200, comparing the smoke concentration signal with a preset concentration signal, and if the smoke concentration signal is larger than the preset concentration signal, comparing the smoke concentration signal with a first preset concentration according to the change concentration and judging whether the room catches fire or not.
And S300, if the change concentration is smaller than the first preset concentration, judging that the room is not on fire, and if the change concentration is not smaller than the first preset concentration, judging that the room is on fire.
The preset concentration signal is characterized by the lowest concentration of the alarm sound of the smoke alarm, and the first preset concentration signal is characterized by the lowest concentration change value for judging fire.
Here, if the smoke concentration signal is smaller than the preset concentration signal, it is determined that the room is not on fire. Compared with the preset concentration signal, the first preset concentration is larger than the preset concentration signal, the preset concentration signal is characterized in that the indoor smoke concentration reaches the lowest concentration possible to catch fire in the judging room, and the first preset concentration represents the lowest concentration possible to catch fire in the judging room.
When the smoke alarm acquires a smoke concentration signal and a change concentration, whether the smoke concentration signal in the room reaches the preset concentration signal or not is acquired by comparing the smoke concentration signal with the preset concentration signal, then, after the smoke concentration signal in the room reaches the preset concentration signal or not, whether the indoor smoke concentration is too high or not due to indoor multi-person smoking is judged, so that whether the change concentration in the preset time is in an increasing state or not is required to be judged, if the change concentration exceeds the first preset concentration, the indoor ignition is indicated, and otherwise, the indoor ignition is not caused. Here, the preset time may be set in advance.
And S400, if the room is not on fire, controlling the alarm in the total monitoring room to not give out alarm sound.
For example, the preset concentration signal is 100ppm at this time, where ppm represents the concentration of the gas volume in the volume of the object. The first preset concentration is 300ppm, the smoke concentration signal obtained in the room is 155ppm, the change concentration in 2 seconds is 100ppm, the smoke concentration signal in the room is larger than the preset concentration signal, but the change concentration signal in the room is smaller than the first preset concentration, the smoke concentration in the room is possibly increased due to smoking of multiple people at the moment, or the smoke concentration is possibly increased due to cooking, at the moment, the alarm in the room is controlled to give out an alarm sound, and the alarm in the general monitoring room does not give out an alarm sound.
If the preset concentration signal is 100ppm and the first preset concentration is 300ppm, the smoke concentration signal obtained from the room is 155ppm, the change concentration in 2 seconds is 350ppm, and the room can be judged to be on fire through calculation, so that the controller controls the smoke alarm in the room to give out alarm sound.
If the indoor ignition is caused by the combustion of the power socket, and at the moment, an alarm sound is sent out through the indoor smoke alarm, indoor personnel can immediately carry out corresponding operation by hearing the alarm sound, the ignition source is timely extinguished, and at the moment, if the smoke alarm in the general supervision control room is directly made to send out the alarm sound, the personnel are further panicked.
And S500, if the indoor fire is judged, comparing the change concentration with a second preset concentration and judging whether the indoor fire is artificially controllable.
In order to acquire the fire condition more accurately after the indoor fire is acquired, and then the fire alarm can be timely reported, therefore, after the indoor fire is determined, whether the indoor fire is controllable needs to be judged according to the smoke concentration information.
S600, if the change concentration is smaller than the second preset concentration, the indoor fire behavior is judged to be controllable, and if the change concentration is not smaller than the second preset concentration, the indoor fire behavior is judged to be uncontrollable.
The second preset concentration is characterized by the lowest change concentration of the smoke alarm with overlarge fire, when the change concentration is smaller than the second preset concentration, the indoor fire is indicated to be manually controllable, only the indoor smoke alarm is needed to be sounded at the moment, otherwise, the indoor fire is judged to be manually uncontrollable, and the smoke alarms in the control room and the general monitoring room are required to be sounded. The second predetermined concentration has a value greater than the first predetermined concentration compared to the first predetermined concentration because the indoor smoke concentration signal exceeds the second predetermined concentration, indicating that the fire in the room is not controllable, and the surface is the indoor fire concentration signal when the indoor smoke concentration signal exceeds the first predetermined concentration.
Here, the fire in the determination chamber is artificially controlled by default if an adult is present in the chamber and the adult is in a state of normal activity. The indoor actual condition is obtained through the camera, no person, only child and the old people inconvenient to move in the room are judged according to the indoor condition shot by the camera, at the moment, the controller judges through the indoor condition shot by the camera, and the controller controls the smoke alarm of the total monitoring room to send out alarm sounds on the assumption that no person, only child and the old people inconvenient to move are in the room, so that the total monitoring room can contact the owner for fire extinguishment at the first time. The camera is installed in resident's room, and the controller only can obtain the photo that the camera took when catching fire or facing the rescue.
S700, if the indoor fire is manually controllable, the indoor alarm is controlled to give out alarm sound, and the general monitoring indoor alarm does not give out alarm sound.
For example, if the preset concentration signal is 100ppm, the first preset concentration is 300ppm, the second preset concentration is 500ppm, at this time, the smoke concentration signal obtained from the room is 155ppm, and the variation concentration is 350ppm, by calculation, it can be determined that the fire in the room is on fire, and the fire in the room is in manual control. Thus, the controller controls the smoke alarm in the room to sound an alarm.
S800, if the indoor fire is not controllable, controlling the indoor alarm and the general monitoring indoor alarm to give out alarm sounds.
If the preset concentration signal is 100ppm, the first preset concentration is 300ppm, the second preset concentration is 500ppm, at the moment, the smoke concentration signal obtained indoors is 155ppm, the change concentration is 550ppm, and the indoor fire can be judged to be on fire through calculation, and the indoor fire is in artificial uncontrollable. Therefore, the controller controls the smoke alarm in the room and the smoke alarm in the general monitoring room gives out alarm sound.
The fire is extinguished from the beginning to the end, and the initial fire is most easily extinguished, but the fire extinguishing method must be correctly applied to effectively extinguish the initial fire. In another embodiment, after determining that the indoor fire is artificially controllable, the method comprises the steps of:
s710, judging whether open fire exists according to the smoke concentration information.
In order to enable residents to extinguish a fire at an early stage of formation, it is necessary to determine whether there is an open fire, specifically, whether there is an open fire according to smoke concentration information, referring to fig. 2, the method comprises the steps of:
s711, an indoor temperature change value is acquired.
S712, comparing the indoor temperature change value with a preset temperature threshold.
S713, if the indoor temperature change value is greater than the preset temperature threshold value, judging that open flame exists in the room.
And S714, if the indoor temperature change value is smaller than the preset temperature threshold value, judging that the indoor open fire exists.
The indoor temperature change value is characterized as a temperature change value of indoor temperature in preset time, and the preset temperature threshold is characterized as the lowest temperature of indoor judgment of open fire.
S720, if open fire exists in the room, the indoor smoke alarm gives out alarm sound and carries out voice broadcasting with reminding to start the fire extinguishing device.
Assuming that the preset time is 2 seconds, the indoor temperature change value is 20 degrees at this time, the preset temperature threshold value is 25 degrees, and the fact that no open fire exists in the room at this time can be judged through calculation of the controller, at this time, the controller needs to control the indoor smoke alarm to send alarm sound and prompt to start the voice broadcast of the fire extinguishing device.
And S730, if the open fire does not exist in the room, the indoor alarm gives an alarm sound and carries out voice broadcasting of reminding to start the smoke exhaust device.
Assuming that the preset time is 2 seconds, the indoor temperature change value is 20 degrees, and the preset temperature threshold value is 25 degrees, the controller can calculate to determine that there is no open flame in the room. At this time, the controller needs to control the indoor smoke alarm to send out alarm sound and carry out voice broadcasting with reminding to start the smoke exhaust device.
In another embodiment, for some old people, the cooking fume exhauster is easy to forget to turn on during cooking, so that cooking fume can be generated, and the old people can be in a fume environment for a long time, so that the risks of lung cancer and cardiovascular and cerebrovascular diseases can be increased. Therefore, when it is determined that the room is not on fire, it may be caused by the oil smoke. The smoke concentration information also comprises smoke particles, and if the room is not ignited, the method comprises the following steps:
s310, acquiring a smoke type according to the smoke particles, and judging whether the smoke type is lampblack.
And S320, if the smoke type is judged to be oil smoke, controlling the indoor alarm to send out a first warning signal.
And S330, if the smoke type is judged not to be the lampblack, controlling the indoor alarm to send out a second warning signal.
Wherein, smog particle characterization is the inside granule of smog, and first warning signal characterization is the signal of reminding people to open the lampblack absorber. The second warning signal is characterized as a signal prompting a person to open a window. In this embodiment, the first warning signal may emit a warning sound at a first interval time through the smoke alarm, and may be accompanied by a bright green light; the first warning signal can send out warning sounds at second intervals through the smoke alarm and is accompanied by bright yellow light; the first interval is shorter than the second interval.
Specifically, for detecting the type of indoor smoke, according to an electrochemical monitoring principle, whether smoke particles exist or not can be monitored, when the smoke particles exist, the smoke type is caused by the smoke, and the controller can control an indoor alarm to send out a first warning signal; otherwise, the smoke type is not caused by the oil smoke, and the controller controls the indoor smoke alarm to send out a second warning signal.
When the fire is uncontrollable, the most important is the help of personnel and the timely fire extinguishing of the fire. If the indoor fire is not controlled artificially, the method comprises the following steps:
s810, acquiring indoor information.
S811, judging whether a person exists in the room according to the indoor information.
And S812, if a person exists in the room, controlling the total monitoring room to give out an alarm sound by an alarm and give out a rescue signal.
And S813, if no person exists in the room, controlling the alarm of the total monitoring room to give out an alarm.
The indoor information comprises whether a person exists or not, the indoor information can be acquired through the camera, and the shouting sound of the indoor person can also be acquired through the sound sensor, so that whether the person exists in the room or not is judged. The rescue signal is characterized by being a signal sent by a smoke alarm in the general monitoring room, at the moment, the smoke alarm in the general monitoring room sends out continuous alarm sound, and the smoke alarm sends out red light.
For a building to hold a plurality of residents, people of other residents need to be evacuated as early as possible when an uncontrollable fire disaster occurs, so that if the indoor fire is artificially uncontrollable, the method further comprises the following steps:
s820, acquiring the fire position according to the smoke position.
S821, acquiring a plurality of surrounding alarm positions according to the fire position.
S823, sequentially controlling the positions of the alarms to give out alarm sounds.
The controller determines the position of the smoke alarm which gives out alarm sound according to the position of the fire, and then can obtain the position of the fire, and can determine the corresponding smoke alarm according to the position of the fire to obtain a plurality of alarms, so as to control the plurality of alarms to give out alarm sound, warn people of fire and need to walk an escape passage.
The implementation principle of the fire monitoring method based on the smoke alarm provided by the embodiment of the application is as follows:
