In the present embodiment, safety monitoring is carried out to region at one, monitor camera 1 is installed in monitoring area, is acquired in real time
The image information of monitoring area.Monitoring area is preset in image intelligent analysis module 2 and invades target, by vehicle in the present embodiment
Or people or ship be set as intrusion target.Monitor camera 1 is persistently monitored monitoring area, and the image of acquisition is believed
Breath is sent in image intelligent analysis module 2.When intrusion target enters monitoring area, image intelligent analysis module 2 passes through figure
As the relative position of recognizer comparison intrusion target and monitoring area, such as judgement intrusion target enters in monitoring area, then determines
Start to strong acoustic device 4, while analysis result is sent to the strong sound intelligent control module 3 of orientation, orients strong sound intelligent control mould
Block 3 receives analysis as a result, orienting the transmitting of strong acoustic device according to reception result control orients strong sound, orients strong sound emission to invading mesh
At mark, warning intrusion target orients strong acoustic device 4 and stops the strong sound of transmitting orientation.Meanwhile it can be sent out according to the difference of penetration distance
The strong sound of orientation of different parameters is penetrated, it, can the lesser strong sound of orientation of emissive porwer such as when the rigid intrusion monitoring region of intrusion target.Such as
Intrusion target ignores warning, continues intrusion monitoring region, can the biggish strong sound of orientation of emissive porwer.It can invading according to intrusion target
Enter the parameter of the strong sound of orientation of distance controlling transmitting.
It further include holder, the monitor camera 1, image intelligent analysis module 2, the strong acoustic device 4 of orientation and orientation are strong
Sound intelligent control module 3 is arranged on holder.Holder is the stabilizer for video camera, plays the role of balance and stability, together
Shi Yuntai can be rotated, so that video camera be driven to rotate, convert monitoring visual field.The strong sound system of intelligent positioning is one at this time
Body structure, holder makes monitor camera 1 have bigger monitoring visual field, while the image information of its acquisition is more stable clear
It is clear.
The image intelligent analysis module 2 may be provided at Cloud Server or remote server or local server.It can
Pre-set image intelligent analysis module 2, in the strong sound system of the arrangement intelligent positioning by the image of other modules and server
Intelligent analysis module 2 connects, and improves arrangement speed.Meanwhile the intelligent analysis module 2 of Cloud Server is set with higher
Arithmetic speed and bigger memory space.
As shown in figure 3, the strong acoustic device 4 of the orientation includes four strong acoustic generators 41 of orientation, four orientations
Line between strong acoustic generator 41 forms quadrangle k；The power ratio of four strong acoustic generators 41 of orientation is equal to four
Orient the distance ratio that strong acoustic generator 41 arrives the diagonal line intersection point o of quadrangle k.The described control of image intelligent analysis module 2 with
The smallest strong acoustic generator 41 of orientation of target range is invaded to start.The strong acoustic generator of the orientation 41 is by image intelligent
Analysis module 2 and the strong sound intelligent control module 3 of orientation control.In the present embodiment, four strong acoustic generators 41 of orientation are set
Set on four vertex of quadrangle k, the strong acoustic generator 41 of orientation described in four be respectively defined as the strong acoustic generator of the first orientation,
The strong acoustic generator of second orientation, third orient strong acoustic generator, the 4th strong acoustic generator of orientation.The strong acoustic generator of first orientation,
The strong acoustic generator of second orientation, third orient the distance point of strong acoustic generator, the 4th strong acoustic generator of orientation to diagonal line intersection point o
Not Wei 500m, 200m, 300m and 250m, then the first strong acoustic generator of orientation, the strong acoustic generator of the second orientation, third orient strong sound
Generator, the 4th power ratio for orienting strong acoustic generator are followed successively by 10:4:6:5.In actual use, the first strong sound of orientation occurs
The quadrangle k that device, the strong acoustic generator of the second orientation, third orient strong acoustic generator, the 4th strong acoustic generator of orientation is formed is to cover
Based on lid monitoring area, strong sound can be oriented by adjusting the strong acoustic generator of the first orientation, the strong acoustic generator of the second orientation, third
Generator, the 4th orient the position of strong acoustic generator to adapt to monitoring area of various shapes.When quadrangle k just covers monitoring
When region, the central point of diagonal line intersection point o substantially monitoring area.When monitor camera 1 finds intrusion target, image intelligent
Analysis module 2 will select the orientation strong acoustic generator 41 nearest with intrusion target range, controls the strong acoustic generator 41 of the orientation and sends out
The strong sound of orientation is penetrated, intrusion target is warned.By above-mentioned setting, guaranteeing that orienting strong acoustic device 4 covers monitoring area
Under the premise of, the distance selection according to each strong acoustic generator 41 of orientation apart from diagonal line intersection point o orients the function of strong acoustic generator 41
Rate keeps the power selection of the strong acoustic generator 41 of the orientation reasonable, and the power for avoiding selection is excessive and causes to waste, while again
Guarantee that everywhere monitoring area can be radiated by orienting strong acoustic device 4.It simultaneously can be flexible according to the shape and landform of monitoring area
The setting position for orienting strong acoustic generator 41 is set, keeps the applicability of the strong sound system of the intelligent positioning wide.
Pass through setting monitor camera 1, image intelligent analysis module 2, the strong acoustic device 4 of orientation and the strong sound intelligent control of orientation
Module 3 warns intrusion target with the strong sound of orientation.The directive property for orienting strong sound is strong, will not generate shadow to ambient enviroment
It rings, avoids generating noise in ambient enviroment；Compared to common acoustic, the effective distance for orienting strong sound is remote, makes the intelligent positioning
The warning distance of strong sound system is remote, can warn intrusion target in remote position；Compared to common acoustic, strong sound is oriented for invading
Enter the warning of target and expel that effect is stronger, while the power of the different strong sound of orientation can be set according to application environment, it is high-power
The strong sound of orientation have and stronger expel effect；Strong sound emission will can be accurately oriented by orienting strong sound intelligent control module 2
To intrusion target, good warning is played to intrusion target and expels effect；Orient strong sound transmitting pass through it is intelligentized
System control, is not necessarily to manual intervention, and intelligence degree is high.
For those skilled in the art, it can make other each according to the above description of the technical scheme and ideas
The corresponding change of kind and deformation, and all these changes and deformation all should belong to the protection model of the claims in the present invention
Within enclosing.
