As shown in fig. 1 and 2, in the embodiment, the effective range 2 of the conventional sound-light alarm includes the areas including the non-control targets 4a, 4b, 4c, 4d and the control target 5a, while the effective range 3 generated by the sound wave expelling system provided by the present invention may only include the area where the control target 5a is located, which is obviously smaller than the effective range of the conventional sound-light alarm, and can selectively warn or expel a specific person.
As can be seen from fig. 1, although the coverage area of the conventional sound and light alarm is large, there is no selectivity, and it is impossible to distinguish the control target 5a from the non-control targets 4a, 4b, 4c, 4d, and even if a certain control effect can be produced, the user-friendly benefit of most of the non-control targets 4a, 4b, 4c, 4d is impaired, so the use effect is not good. The present invention, however, uses the sound focusing technique so that the repulsive sound wave can be focused in a small range, and can accurately strike the prevention and control target 5a, but the prevention and control targets 4a, 4b, 4c, 4d are not affected.
As shown in FIG. 2, the height from the ground of the intelligent direction-changeable sound wave expelling system 1 is H, a horizontal turning angle α and a vertical turning angle β. the setting of the height from the ground H can make the expelling sound wave accurate to people, and the installation height H exists in the horizontal direction, so that the intelligent direction-changeable sound wave expelling system 1 does not affect the non-prevention and control targets 4a, 4b, 4c and 4d at the same horizontal height when in use.
As shown in fig. 1, 2 and 3, the intelligent direction-changeable sound wave expelling system 1 is not only used at a single angle, and due to the electric pan-tilt 14, the intelligent direction-changeable sound wave expelling system has strong maneuverability on the basis of being accurate to people when used, the horizontal steering angle α can reach 170 degrees, and the vertical steering angle β can reach 110 degrees.

The intelligent management platform 11 may manage several sets of intelligent steerable acoustic ejection systems distributed within the network 6 simultaneously.
As can be seen from fig. 3, the control command and the configuration information of the intelligent management platform 11 are issued through the network 6, and the related control command and the configuration information are processed by the intelligent camera module 12 and then issued to the directional acoustic wave module 13 and the electric pan-tilt 14. The intelligent camera module 12 manages the sound production of the directional sound wave module 13 and the rotation of the electric pan-tilt 14.
In the embodiment, as can be seen from fig. 4, the coverage of the sound wave expelling effective range 3 of the present invention is not consistent with the coverage of the wide-angle camera shooting range 7, and the wide-angle camera shooting range 7 of the present invention is larger than the sound wave expelling effective range 3 of the present invention, because the smart camera is responsible for the collection and analysis of real-time conditions in a larger range, if the collection range is smaller, the effect of the smart analysis in the full range cannot be achieved. The effective range 3 of the sound wave expelling is smaller so as to more accurately expel the sound wave to the prevention and control target.

Data and various information interactions exist among the camera 122, the intelligent analysis component 123 and the storage component 125, such as configuration information, black and white lists of human faces and other information. The intelligent analysis component 123 is responsible for intelligent analysis and behavior judgment of behaviors including facial recognition, limb motion recognition, border-crossing detection and the like, and the judgment result is used for driving the electric pan-tilt 14 to point to the prevention and control target 5a, and meanwhile, the analysis result is uploaded to the intelligent management platform 11. The storage component 125 may be in the form of a micro SD card or a Flash chip.

The audio power amplifier 133 adopts a D-type power amplifier form, and has the advantages of small heat generation, high power and the like. Class D power amplifiers refer to class D audio power amplifiers (sometimes also referred to as digital power amplifiers). By controlling the on and off of the switching unit, the amplifier driving the speaker is called a class D amplifier. Class D amplifiers are suitable for use in the present invention or other high power applications. The efficiency of the class D power amplifier can reach 100% under the ideal condition. The sound source 134 adopts 2k-4kHz sine wave frequency sweeping signals, and according to the listening characteristics of human ears, the human ears are most sensitive to the sound with the frequency of 2k-4kHz, and the larger hearing sensitivity can be achieved only by smaller amplitude in the frequency band.

Generally, the method comprises the following steps of after-treatment and passive prevention and control, namely monitoring, problem finding, calling monitoring and personnel handling. There are few prior or in-advance treatment modes, namely condition anticipation and advance treatment, and the invention can perform real-time treatment on the prior or in-advance event.
2. The intelligent direction-changeable sound wave expelling system provided by the invention has stronger sound stimulation and can not cause permanent damage to human hearing. According to the characteristics of audition of human ears, the developed 2k-4k sound source has strong stimulation to the human ears. In the 2k-4k audio frequency range, the sound pressure level required to achieve the same listening loudness of the human ear is the lowest, the sound production efficiency is the highest in this interval, and the human ear is the most sensitive. By matching with a high-power D-type power amplifier, the sound intensity of the invention reaches more than 125dB, people can be overloaded and efficiently driven away in a short time, the escape desire is strong, the device is far away from the scene of the incident, and the human body cannot be injured and the hearing can not be damaged.
3. The invention not only has the general face recognition function, but also can automatically recognize blacklist personnel, automatically recognize human body characteristic actions (such as fighting) and automatically start the full-automatic mode integrating sound wave expelling, thereby greatly reducing the workload of watchmen.
4. The invention has the capability of accurately controlling people, and the prior security equipment can only control a group of people or a class of people, has poor prevention and control effect and is easy to accidentally injure irrelevant people.
