Special flexible multifunctional acoustic wave denial equipment for police car and a control method thereof

Abstract

The invention relates to special flexible multifunctional acoustic wave denial equipment for a police car and a control method thereof. The equipment is installed in a police car and is powered by a police car vehicle-borne power supply. The device comprises a computer, a power amplifier circuit, a camera, a single chip microcomputer, and a plurality of transducers. The camera is connected to the computer which is connected to the single chip microcomputer, and the single chip microcomputer is connected to a plurality of MOS tubes. Each of the MOS tubes is connected to a transducer in series and then is connected in parallel to form a transducer array. The transducer array is connected to the power amplifier circuit in parallel to form acoustic wave denial devices. The acoustic wave denial devices are distributed at two sides of the camera. According to the special flexible multifunctional acoustic wave denial equipment and the control method, according to the direction and distance of a dispersed target, an acoustic wave emitting direction and a maximum sound pressure level are adjusted, the equipment has a function of flexible combination, and thus the electric energy use amount of the acoustic wave denial equipment is reduced. A warning lamp on a shell has a warning function and has the advantages of a light weight and a small volume, and so the police car has the functions of reducing air resistance and reducing the fuel consumption of the police car in the process of running.

Description

technical field [0001] The invention relates to the technical field of strong sound rejection equipment, in particular to a special flexible and multifunctional sound wave rejection equipment for police cars and a control method. Background technique [0002] Sound wave rejection equipment is a directional sound transmission device that can realize long-distance shouting, warning, and deterrent functions, and can transmit unusually clear sound effects at extremely long distances, even through certain buildings. The sound wave rejection equipment is different from the traditional sound wave equipment. It has the characteristics of strong directivity, long action distance, high sound pressure level and safe use. It not only ensures the effectiveness and accuracy of long-distance sound transmission, but also ensures the Disperse the security of the target population. [0003] In the prior art, people usually install the sound wave rejection equipment on the top of the police c...

Problems solved by technology

[0003] In the prior art, people usually install the sound wave rejection equipment on the top of the police car, so that the sound wave rejection equipment can achieve the purposes of anti-terrorism, stability maintenance, regional alert, law enforcement, protection, etc., but the vehicle-mounted sound wave rejection equipment in the prior art When the equipment is working, all the transducers installed are always used and closed at the same time, and the flexible combination of the transducers cannot be performed according to the location of the dispersing target and the distance of the dispersing target, so that the vehicle power supply The electricity consumption of the

Moreover, the vehicle-mounted sound wave rejection equipment in the prior art has a large overall weight, large volume, and unreasonable structural design, so that the police car generates a lot of air resistance during driving, especially when driving at high speed, which is not conducive to the driving process of the police car. reduction in fuel consumption
