Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, a fire alarm method based on the internet of things disclosed in the embodiment of the present invention mainly includes the following steps:
s101, obtaining temperature values of a plurality of monitoring points;
s102, obtaining smoke concentration values of a plurality of monitoring points;
the main purpose of the two steps is to collect information for providing judgment basis for follow-up. There are two pieces of information collected, one being temperature and one being smoke concentration. When a fire disaster occurs in a building, open fire and dense smoke can appear, the two signals are easy to acquire, and the acquisition technology is mature.
S103, displaying the obtained temperature values and the smoke concentration values of the plurality of monitoring points;
the step is to display the collected temperature values and the smoke concentration values of the plurality of monitoring points, wherein the display places are located at each monitoring point, and certainly, the display places can also be displayed in a background, a monitoring room, a security room and the like.
S104, comparing the obtained temperature value and the corresponding early warning value of the same monitoring point with the corresponding early warning value respectively to obtain a first comparison value and a second comparison value;
when the first comparison value and the second comparison value are both greater than the early warning value, each monitoring point sends out alarm information and gives out the position of the abnormal monitoring point;
when one of the first comparison value and the second comparison value is larger than the corresponding alarm value, each monitoring point sends out alarm information and gives the position of the abnormal monitoring point.
Judging according to the acquired temperature value and smoke concentration value of each monitoring point, wherein the judging modes comprise two modes, the first mode is that the temperature value and the smoke concentration value of the same monitoring point are respectively compared with corresponding early warning values, and when the temperature value and the smoke concentration value exceed the early warning values, a fire disaster occurs at the monitoring point; and the second method is to compare the fire alarm values with corresponding alarm values respectively, wherein when one alarm value exceeds the corresponding alarm value, the fire disaster appears at the monitoring point, so that the judgment can improve the judgment accuracy and reduce the probability of misjudgment.
After a fire occurs, each monitoring point sends out alarm information and gives the position of the abnormal monitoring point, so that the notification coverage area can be increased as much as possible, and when an escape person escapes, the escape person can plan a proper escape route according to the position of the escape person and the relative position of the abnormal monitoring point, and the escape rate can be effectively increased.
For example, in a high-rise building, a monitoring point can be arranged on each floor, so that an escape person can judge whether a fire point is positioned below or above according to the obtained information, then a proper escape route is selected, the escape person escapes from the high-rise building as soon as possible when the escape person is positioned below the fire point, the escape person can pass through the fire point when the escape person is positioned above the fire point, and the escape person can escape to a high place or wait for rescue at home when the escape person cannot pass through the fire point.
As regards the manner of presentation of the fire point, it can be directly shown as several stories, or it can be presented schematically in a plan view identical to the building.
In order to further improve the success rate of escape, in an embodiment, when one of the temperature value and the smoke concentration value exceeds the early warning value, image information corresponding to the monitoring point is obtained, and then the obtained image information is displayed to each monitoring point.
Therefore, the escape personnel can immediately know the actual situation of the fire point while obtaining the alarm information, can make more accurate judgment, and can escape from the building at the fastest speed if the position of the escape personnel is above the fire point and the escape personnel finds that the exit personnel has the crossing condition. Of course, when the situation such as false alarm and detection occurs, the property can be informed to be processed or returned, and the escape is not needed.
In the process of giving out image information, the possibility of privacy leakage exists, so when the temperature value and the smoke density value are both reduced to be lower than the corresponding early warning value, the image information channel for obtaining the corresponding monitoring point is closed, and the condition of privacy leakage is reduced.
When the image information channel corresponding to the monitoring point is closed, two modes of immediate closing and delayed closing are available, wherein delayed closing means that after the temperature value and the smoke concentration value are both reduced to be lower than the corresponding early warning values, the image information still has a period of time, and the period of time is mainly used for avoiding the condition that the acquired temperature value and the smoke concentration value fluctuate to cause misjudgment.
The alarm information is sent by various signals such as sound signals, light signals, vibration signals and the like, so that the probability of receiving by people in the building is improved.
When the temperature value and the smoke concentration value are both reduced to be lower than the corresponding early warning value, the alarm information is stopped from being sent, and the phenomenon that the normal life order is disturbed by long-time alarm information sending after the normal state is recovered is avoided.
Certainly, the alarm information is stopped being sent in two modes, namely immediate closing and delayed closing, wherein the delayed closing means that the alarm information is still sent for a period of time after the temperature value and the smoke concentration value are both reduced to be lower than the corresponding early warning values, and the time is mainly used for avoiding the situation that the collected temperature value and the smoke concentration value fluctuate to cause misjudgment.
The invention also discloses a fire alarm device, which mainly comprises the following modules:

In one embodiment, in order to provide more information, an image function is added, and the function is mainly realized by an image information acquisition module and a third display module, wherein the image information acquisition module is used for acquiring image information of an environment where the image information acquisition module is located, and the third display module is used for displaying the acquired image information.
The image information acquired by the image information acquisition module is the image information of the abnormal monitoring point, the number of the third display modules is multiple, and the image information displayed by the third display modules is the same and is the image information of the abnormal monitoring point. Since the fire is most violent in the first place of a general fire, and particularly, in the case of a fire, it is difficult to determine which place is the most violent through an image according to the development of the fire, so that in the present embodiment, only the first place of the fire is displayed, and the determination can be made according to the fire at the first place.
