Detailed Description
The embodiment of the application discloses a building intelligent sensing method.
Referring to fig. 1, a building intelligent sensing method includes:
and S100, acquiring the smoke concentration detected by a preset smoke sensor.
In this embodiment, the smoke sensor is provided with a built-in buzzer, and the buzzer sounds a warning sound after the smoke sensor gives an alarm.
In practice, a fire is usually accompanied by the production of a large amount of smoke containing a large amount of minute solid particles floating in the air, and a smoke sensor is used to monitor the concentration of the solid particles in the air.
In addition, the smoke sensor can also sense smoke generated by tobacco.
S200, acquiring a preset temperature value detected by the temperature sensor.
The temperature sensor is used for detecting the temperature in the corridor, and particularly, the temperature sensor can be replaced by a temperature and humidity sensor.
In a specific implementation, one smoke sensor and one temperature sensor may be installed at each fixed distance from the roof of each corridor.
It should be noted that there is no execution sequence between step S100 and step S200, that is, the execution sequences between step S100 and step S200 may be interchanged.
And S300, based on the smoke concentration and the temperature value, giving out fire early warning.
The central control host can predict the fire according to the smoke concentration and the temperature value and send out fire early warning.
Specifically, the fire early warning comprises a first-level fire early warning and a second-level fire early warning;
referring to fig. 2, based on the smoke concentration and the temperature value, the step of sending out the fire early warning includes:
s301, judging whether the temperature value is larger than or equal to a preset first temperature threshold value.
The development process of fire is mainly divided into 5 stages, namely an incubation stage, an initial stage, a development stage, a fierce stage, a descent stage and an extinction stage. In the embodiment, the prediction is only made in the initial stage and the incubation stage of the fire;
in the stage of fire incubation, a large amount of smoke is usually generated firstly, open fire is not formed, and the combustion temperature is gradually increased; in the initial stage of a fire, the smoke flowing speed is slow, open fire is generated, the flame of the open fire is not high, the combustion temperature is gradually increased, and the radiant heat is gradually enhanced; in the development stage of fire, a large amount of smoke is diffused, the combustion temperature is further improved, the radiant heat is further enhanced, the combustion speed is accelerated, and open fire gradually spreads; in the violent stage of the fire, the combustion temperature is highest and the radiant heat is strongest. The initial stage and the incubation stage of the fire are the optimal fire extinguishing period.
In this embodiment, the first temperature threshold represents the temperature in the corridor at the initial stage of the fire. In this embodiment, the first temperature threshold is set to 60 degrees celsius, that is, when the temperature in the corridor is greater than or equal to 60 degrees celsius, the central control host determines that the normal indoor temperature is exceeded, and determines that there is a fire risk, and at this time, the central control host executes the next step.
And S302, if so, judging whether the smoke concentration is greater than or equal to a preset first smoke concentration threshold value.
When the temperature value detected by the temperature sensor is greater than or equal to the first temperature threshold, the central control host judges whether the smoke concentration is greater than or equal to the first smoke concentration threshold, and the first smoke concentration threshold corresponds to the smoke concentration at the initial stage of the fire. In this embodiment, the first smoke concentration threshold is set to 500ppm, that is, when the smoke concentration detected by the smoke sensor is greater than or equal to 500ppm, the central control host executes the next step.
And S303, if so, sending out a first-level fire early warning.
If the temperature value is greater than or equal to the first temperature threshold value and the smoke concentration is greater than or equal to the first smoke concentration threshold value, the central control host judges that the fire is in an initial stage and sends out first-level fire early warning.
Referring to fig. 2, after the step of issuing the primary fire warning, the method further includes:
s304, judging whether a preset flame sensor detects a flame signal or not;
after the central control host sends out the early warning of the first-level fire, the central control host judges whether the flame signal detected by the flame sensor is received, if so, the central control host indicates that open fire is generated at the moment, and the fire is put out and put out for life as soon as possible.
S305, if yes, judging that fire occurs, and sending fire information to a receiving end;
the central control host receives the flame signal detected by the flame sensor, namely, the flame signal indicates that open fire is generated, and the central control host judges that fire occurs and sends fire information to the receiving end. The specific receiving end can be a computer, a mobile phone or a tablet.
If the central control host does not receive the flame signal detected by the flame sensor, step S302 is executed.
S306, if not, judging whether the smoke concentration is larger than or equal to a preset second smoke concentration threshold value.
In this embodiment, the second smoke concentration threshold is set at 200 ppm. The first smoke concentration threshold is greater than the second smoke concentration threshold.
It should be noted that the first smoke density threshold and the second smoke density threshold need to be set according to the size of the space and the required sensitivity, and the first smoke density threshold and the second smoke density threshold set in this embodiment are only used as references.
And S307, if so, sending out a secondary fire early warning.
If the temperature value is greater than or equal to the first temperature threshold, the smoke concentration is less than the first smoke concentration threshold and is greater than or equal to the second smoke concentration threshold, the central control host judges that the fire disaster is in the incubation stage, and secondary fire early warning is sent out.
If not, go to step S310.
S308, if the temperature value is smaller than the first temperature threshold, whether the temperature value is larger than or equal to a preset second temperature threshold is judged.
In this embodiment, the second temperature threshold is set to 50 degrees celsius. For example, if the temperature value is 55 degrees, at this time, the temperature value is less than the first temperature threshold value by 60 degrees celsius and is greater than or equal to the second temperature threshold value by 50 degrees celsius, and at this time, the central control host executes the next step.
The first temperature threshold is greater than the second temperature threshold.
And if so, executing the step of judging whether the smoke concentration is greater than or equal to a second smoke concentration threshold value. I.e. step S306 is performed.
If the temperature value is between the second temperature threshold and the first temperature threshold, the central control host compares the smoke concentration with the second smoke concentration threshold.
And if the smoke concentration is greater than or equal to the second smoke concentration threshold value, executing the step of sending out the secondary fire early warning. Namely, step S307 is executed.
If the temperature value is between the second temperature threshold and the first temperature threshold and the smoke concentration is greater than or equal to the second smoke concentration threshold, the central control host determines that the fire is in the incubation stage. Because the first smoke concentration threshold is greater than the second smoke concentration threshold, when the temperature value is between the second temperature threshold and the first temperature threshold and the smoke concentration is greater than or equal to the first smoke concentration threshold, the central control host also judges that the fire is in the incubation stage and sends out secondary fire early warning.
If the temperature value is smaller than the second temperature threshold, step S311 is executed.
It should be noted that the emergency degree of the first-level fire warning is greater than that of the second-level fire warning.
Specifically, after the step of sending out the secondary fire warning, the method comprises the following steps:

When the temperature in the corridor is higher than the normal room temperature value and the smoke concentration is in a normal condition, the condition is an abnormal condition.
And S310, if so, judging that an abnormal condition occurs, and sending an alarm signal to a receiving end.
Based on step S309, if the temperature in the corridor is higher than the normal room temperature value and the smoke concentration is in the normal condition, the central control host determines that the condition is abnormal, and sends an alarm signal to the receiving end, so that the background staff can see the alarm signal and process the alarm signal in time.
Specifically, after the step of sending the alarm signal to the receiving end, the method further comprises the following steps:
s311, judging whether the temperature value is smaller than a second temperature threshold value;
after the step of sending the alarm signal by the central control host, the central control host judges whether the temperature value detected by the temperature sensor is smaller than a second temperature threshold value. And if the temperature value is less than the second temperature threshold value, indicating that the temperature in the corridor is within the normal room temperature range.
S312, if yes, judging whether the smoke concentration is greater than or equal to a second smoke concentration threshold value;
if the temperature value is smaller than the second temperature threshold value, namely the temperature in the corridor is in the normal room temperature range at the moment, the central control host machine compares the smoke concentration detected by the smoke concentration sensor with the second smoke concentration threshold value. In this embodiment, the second smoke concentration threshold represents the smoke concentration of the largest smoking in the corridor, that is, people working in the office building are prohibited from smoking in the corridor by setting the second smoke concentration threshold.
And S313, if so, sending smoke alarm information to a receiving end.
If the smoke concentration is higher than the second smoke concentration threshold value, the central control host machine judges that someone smokes in the corridor at the moment, and sends smoke alarm information to the receiving end.
If not, go to step S315.

when the central control host judges that a person smokes in the corridor, the exhaust fan is started to discharge smoke in the corridor. Specifically, the exhaust fan and the central control host can be connected through a wire or a wireless connection. And after the central control host starts the exhaust fan, the current smoke concentration in the corridor is obtained in time.
Specifically, after the step of obtaining the smoke concentration detected by the smoke sensor, the step of determining whether the smoke concentration is greater than or equal to a second smoke concentration threshold is performed.
And S315, if the smoke concentration is smaller than the second smoke concentration threshold value, controlling the exhaust fan to be closed.
And if the smoke concentration acquired by the central control host through the smoke sensor is less than the second smoke concentration threshold, indicating that the smoke concentration in the corridor is restored to a normal level at the moment. At the moment, the central control host controls the exhaust fan to be closed.
Specifically, after the step of sending out the fire early warning, the step of sending out alarm signal and the step of sending out smoke alarm information, include:
and S316, calling a preset real-time picture of the camera.

In the concrete implementation, the number of floors can be corresponded in the corridor codes, namely, the background staff can know the floors corresponding to the corridor according to the corridor codes.
When the smoke sensor gives an alarm, the central control host acquires the smoke sensor code of the smoke sensor giving the alarm from the management database. The smoke sensor alarm in the embodiment of the application refers to the fact that the smoke concentration detected by the smoke sensor is larger than or equal to a first smoke concentration threshold value or the smoke concentration is larger than or equal to a second smoke concentration threshold value.
