Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, specific embodiments accompanied with figures are described in detail below, and it is apparent that the described embodiments are a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making creative efforts based on the embodiments of the present invention, shall fall within the protection scope of the present invention.
Example 1
The condition of gathering nature appears in the public place, and security protection staff is more still adopt artificial form to remind, and is not only inefficient, can't in time remind corresponding personnel to pay attention to the protection distance, also can additionally increase a large amount of costs of labor simultaneously, does not accomplish to play more security protection effects through limited staff.
Therefore, referring to fig. 1 and fig. 2, the present invention provides a self-adjusting security alarm system, which includes:
the infrared detection module 100 is configured to acquire a thermal image of a person in a specified area in real time, determine whether the density of the person in the specified area reaches a threshold value according to the thermal image, and send a determination result to the self-adjustment module 200;
the self-adjusting module 200 is connected with the infrared detection module 100, and autonomously adjusts the security alarm module 300 according to the judgment result, including increasing and decreasing the broadcast loudness and the broadcast frequency;
and the security alarm module 300 is connected with the self-adjusting module 200 and used for making regional broadcast reminding through broadcasting.
It is understood that thermal imaging of personnel can be achieved according to infrared technology, so that monitoring of the number of personnel in a designated area is achieved, and when the number of personnel reaches an alarm value, corresponding security and protection alarm measures can be carried out through the self-adjusting module 200.
The self-adjusting module 200 is used for performing autonomous intelligent adjustment on the security alarm module 300, and increasing broadcast loudness and broadcast frequency when the number of people reaches an alarm value; when the number of people is long, generally set to 1h, and the alarm value is not reached, the probability that the situation of people gathering occurs near the monitoring time is lower by default, and the loudness and the playing frequency of the broadcast are properly reduced, as shown in the following table 1, the table is a broadcast state performance table under different conditions:
table 1: broadcast status performance table under different conditions
Situation type red early warning orange early warning green security
Broadcast loudness (DB) 15010050
Play frequency (time/min) 1053
As can be seen from table 1 above, when the infrared detection module 100 detects that a large amount of aggregation occurs in a designated area, which is generally set to be more than 30% of the designated area, the occurrence of red warning is defined, the broadcast loudness is increased to 150db at this time, and the playing frequency is increased to 10 times/min; when the infrared detection module 100 detects that a small amount of aggregative conditions occur in a designated area and is generally set to be less than 10% of the designated area, an orange early warning is defined to occur, the broadcast loudness is adjusted to 100db at the moment, and the playing frequency is adjusted to 5 times/min; when the infrared detection module 100 detects that no aggregation condition occurs in the designated area or the aggregation duration is less than 6s, green security is defined to occur, the broadcast loudness is adjusted to 50db at the moment, and the playing frequency is adjusted to 3 times/min.
Further, the infrared detection module 100 includes:
the partition unit is used for partitioning the designated area;
the infrared detection unit is connected with the partition unit and is used for respectively acquiring the thermal images of the personnel in the designated area after the partition in real time;
the judgment unit is connected with the infrared detection unit and used for respectively judging whether the personnel density in each designated area after partitioning reaches a threshold value according to the thermal image;
and a sending unit connected to the determining unit, for sending the determination result to the self-adjusting module 200.
It should be noted that:
the partitioning unit is used for partitioning the designated area, on one hand, the use of high-quality infrared detection devices can be reduced, so that the cost is reduced, on the other hand, after a certain designated area is detected and partitioned, each detection device can be respectively managed in a respective monitoring area, the monitoring accuracy is realized, and meanwhile, the complexity of algorithm processing is reduced.
It is worth noting that: the partition unit carries out partition of the designated area according to monitoring of 10-12 m2 by each infrared detection unit.
And the infrared detection unit generally adopts a passive infrared/microwave infrared detector.
And the judgment unit adopts an AT89Sxx series single chip microcomputer.
It is worth noting that: and defining the personnel density in each designated area to reach 2 artificial monitoring threshold values per square meter.
Further, the determining unit further includes a delay determining unit for determining a time duration of the monitoring threshold reached when the determining unit determines that the monitoring threshold is reached, and transmitting the determination result to the self-adjusting module 200 through the transmitting unit when the time duration reaches a predetermined value.
Wherein the defined value is 6 s.
It is understood that the delay determination unit determines the duration of the reaching of the monitoring threshold, and considering that the mobility of the crowd exists, when the monitoring threshold is reached to trigger the self-adjusting module 200, the density of people is reduced below the monitoring threshold at the next moment along with the movement of the crowd, so that the calculation amount and the ineffective intervention of the self-adjusting module 200 can be greatly reduced by introducing the delay determination unit for determination.
When the duration reaches a defined value, the self-adjusting module 200 increases the loudness of the broadcast and speeds up the frequency of the broadcast.
According to the invention, the infrared detection module is used for judging the adjustment change condition of the self-adjusting module, the self-adjusting module is used for increasing and decreasing the broadcast loudness and the broadcast frequency, and the intelligent detection means is used for replacing the manual operation mode for operation, so that a large amount of manual investment is reduced, meanwhile, more security effects are achieved through limited staff, and the security control of public places in an epidemic situation period is facilitated.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
