Intelligent direction-changeable sound wave expelling system

Abstract

The invention discloses an intelligent direction-changeable sound wave expelling system. The system comprises a directional sound wave module, an electric pan-tilt and an intelligent vidicon module. The directional sound wave module comprises a sound production assembly and a sound directional assembly used for limiting the spread direction of sounds produced by the sound production assembly. Theelectric pan-tilt comprises a translation shaft module used for driving the directional sound wave module to horizontally move and a pitching shaft structure used for driving the directional sound wave module to do pitching motion. The intelligent vidicon module comprises a vidicon and an intelligent analysis assembly used for carrying out face recognition or behavior recognition on images. When set human faces or set behaviors are recognized, the intelligent analysis assembly controls the electric pan-tilt to drive the directional sound wave module to face the positions of the set human facesor set behaviors and controls the directional sound wave module to produce sounds. By means of the system, criminals or criminal behaviors can be recognized, active in-process intervention can be selectively carried out on criminals in crowds, and the active defense function is achieved.

Description

technical field [0001] The invention relates to the field of intelligent security technology, in particular to an intelligent variable-directional sound wave expulsion system. Background technique [0002] With the development of society, the flow of people has increased, and the flow of people has become more and more complex. The management pressure on the floating population is increasing. The number of public security cases is increasing year by year. The safety management of people and the active prevention of safety are put on the agenda, especially It is a challenge to safety management. [0003] In recent years, cases of theft of important items and cases of missing students have been on the rise, destroying a good social security environment and having a serious impact on family life. Although the government has increased the distribution of social monitoring points and achieved important results, electronic monitoring and checkpoints are still passive and static s...

AI Technical Summary

Problems solved by technology

Although the government has increased the distribution of social monitoring points and achieved important results, electronic monitoring and checkpoints are still passive and static safety precautions, which cannot provide real-time and active alarms or reminders, and cannot activate active prevention for safety. The investment cost of case detection is getting higher and higher, the public security police often suffer from passive prevention, and there is no effective means to take the initiative to attack

The only prevention and control equipment such as sirens and lights can play a certain role in active prevention and control, but there is no selectivity for dealing with the crowd, and the deterrence is not enough to achieve the expected treatment effect
