Description

Remote sound servo monitor

Technical Field

The utility model relates to a servo watch-dog of long-range sound belongs to control technical field.

Background

With the progress of society and the improvement of living standard of people, safety is more and more important to people, including the safety of people and objects. In order to ensure the safety to the maximum extent, a large number of monitoring cameras are installed in corners of the society, even buses and private cars. However, for some places with complex environments and large areas, the arrangement difficulty of the monitoring cameras is high. If a fixed camera is adopted, the camera needs to be installed in multiple arrangements and angles, which can increase economic burden; if the camera with the rotary pan-tilt is adopted, although the installation number can be reduced, a monitoring blind area is left in the rotating process.

Disclosure of Invention

The utility model aims at solving the above problem, provide long-range sound servo watch-dog, confirm the direction of control according to the sound signal's in a distance amplitude intensity, realize single watch-dog and to the full coverage control of complex environment.

The utility model provides a technical scheme that its technical problem adopted is:

the remote sound servo monitor comprises a monitoring cloud deck provided with a camera, an angle detection module for measuring a rotation angle is arranged on the monitoring cloud deck, a plurality of remote sound acquisition devices installed at a remote position are further included, an electronic control device is arranged in the cloud deck and comprises a processor for performing centralized control, the processor is connected with the camera and the angle detection module, the remote sound servo monitor also comprises a WiFi module and a cloud deck driving device which are connected with the processor, the WiFi module is connected with the remote sound acquisition devices through a wireless WiFi network, the remote sound acquisition devices comprise a second processor for performing centralized control and a power interface, the second processor is connected with a second WiFi module and a sound acquisition module, the second processor is provided with a filtering algorithm to remove signals which are output by the sound acquisition module and are lower than an environmental noise threshold value, the processor is internally provided with a control method.

The holder driving device comprises a driving motor and a gear set.

The angle detection module is set as an absolute value type encoder.

The beneficial effects of the utility model are that: the sound collection device is arranged at an important position of a monitoring environment, the monitoring direction is selected according to the amplitude of the sound signal, and the single monitor is used for monitoring the complex environment in a full-coverage mode, so that the installation quantity of the monitors is reduced, and the sound collection device has good economic value.

The processor is internally provided with a control method, and the control method comprises the following steps:

(1) and sound signal acquisition: the remote sound acquisition device samples sound signals at different positions through the sound acquisition module; the processor reads the sound signals of the remote sound acquisition device through the WiFi module, if no signal exists, the step (2) is executed, otherwise, the comparison is carried out, the position with the highest sound amplitude is obtained, and the step (3) is executed;

and (1) collecting sound of each position of a monitoring place to determine an adopted monitoring mode.

(2) And the tripod head patrols: the processor controls the monitoring holder to rotate at a constant speed through the holder driving device, and the processor performs video acquisition through the camera and stores the video;

the step (2) is a common inspection mode, and aims at quiet monitoring places without places needing important attention.

(3) And fixed-point monitoring: the processor controls the monitoring holder to rotate through the holder driving device, the camera points to the position with the highest sound amplitude, and the processor performs video acquisition and storage through the camera.

And (3) a fixed-point monitoring mode is adopted, and the condition that the sound at a certain position in a monitoring place exceeds an environmental noise threshold value, the amplitude is maximum and important attention is needed is met.

And (3) after the step (2) or the step (3) is finished, returning to the step (1) again, and collecting the sound signals again and judging.
