A kind of intelligent monitoring device
Technical field
The invention belongs to monitoring device technical fields, and in particular to a kind of intelligent monitoring device.
Background technique
Monitor refers to the general name that video, audio signal are included and stored using camera shooting storage equipment, such as China
Monitoring camera disclosed in patent CN102984445A is arranged in shell including camera and the shell being mounted on camera
Functional module, video reception output device and power supply unit, camera, functional module and video reception output device respectively with
Power supply unit connection, as closed-circuit control is increasingly popularized civilian and commercial use, monitor is widely used in various necks
Domain all plays the role of escorting in business administration and social security.
But in outdoor monitor, due to being chronically exposed in air, up and-down vehicle and pedestrian can make
Dust raises, thus the mirror surface of monitor usually can adhering dust, and monitor is typically mounted at higher position, clean
When it is inconvenient, so the monitor that uses will affect the shooting matter of monitor due to being infected with more dust for a long time
Amount, to reduce the effect of monitoring and shooting.
The prior art is usually cleaned after dust excessively influences shooting quality again, but since dust is viscous for a long time
It is attached on mirror surface, cleaning difficulty is larger after exposing to the sun and rain.
Summary of the invention
The purpose of the present invention is to provide a kind of monitoring devices, to overcome the mirror surface of monitor of the prior art viscous for a long time
The problem that attached dust makes cleaning difficulty big.
A kind of intelligent monitoring device of this programme, including camera, power supply unit and the shell being mounted on camera, institute
It states shell and is equipped with dust catcher, dust detector and the controller being electrically connected with power supply unit, the output of the dust detector
End is electrically connected with the input terminal of controller, and the output end of the controller is electrically connected with the input terminal of dust catcher, the dust catcher
There are two at least, set up separately in the two sides of mirror surface, the dust catcher includes suction inlet, and the suction inlet is towards mirror surface.
The working principle of the invention: intelligent monitoring device of the invention, including camera, power supply unit and it is mounted on camera shooting
Dust catcher, dust detector and the controller being electrically connected with power supply unit, dust detector is arranged in shell on head on shell
The dust concentration of environment is detected, once discovery dust concentration is more than the threshold value of setting, control will be passed the signal along to
On device, controller just issues the signal of starting to dust catcher, due to dust catcher at least there are two, and set up separately the two of mirror surface
Dust on mirror surface after starting dust catcher, can be adsorbed by suction inlet towards mirror surface, avoid dust in mirror by side
It is stopped on face and also avoids to need the problem of cleaning.
Beneficial effects of the present invention: intelligent monitoring device of the invention does not glue also using preparatory effect in dust
With regard to carrying out dust suction processing before being attached on mirror surface, therefore even if blowing and raining, mirror surface will not be acted on dust, so that mirror surface can
It is clean to be always maintained at, cleaning step is avoided, while also ensuring the shooting quality of intelligent monitoring device.
Preferred embodiment one, the dust catcher further include sweep-up pipe, collecting chamber, gas chamber, air bag and electric pushrod, and suction inlet is set
It sets on sweep-up pipe, wherein sweep-up pipe, collecting chamber, gas chamber and air bag are sequentially connected to, and gas chamber is cylindrical, and gas chamber is equipped with exhaust
Mouthful, the cover plate that exhaust outlet is completely covered is hinged on gas chamber, the side wall of air bag is in corrugated tube shape, and air bag is connected with to compressed gas
The electric pushrod of capsule, the electric pushrod are electrically connected power supply unit.In use, suction inlet is directed at mirror surface, electric pushrod
Starting pushes air pocket motion, compresses to the air of the gas chamber of fixed volume, generates pressure, under the effect of the pressure, cover plate
It is opened, air is discharged from exhaust outlet, and near vacuum in entire dust catcher generates negative pressure, in suction inlet and exhaust ports and outside
Boundary's atmospheric pressure generates pressure difference, is discharged on air bag, air bag Rapid reset, forms suction, under the action of suction, cover plate is closed
It closes, dust is inhaled into air by suction inlet, is entered in collecting chamber by sweep-up pipe and is collected, and dust is being vented in order to prevent
When be discharged, therefore one-way cock is set on sweep-up pipe, filter disc is set in exhaust ports.
Further, the caliber of the sweep-up pipe is sequentially increased towards collecting chamber direction.In order to keep suction bigger, ash is being absorbed
When dirt, because absorption area is limited, so that the suction of unit area becomes much larger, fast and easy draw dust.
Preferred embodiment two, to state dust catcher include that the sweep-up pipe being sequentially communicated, electric blower room and dust bag, suction inlet are set
It sets on sweep-up pipe, electric blower is equipped in electric blower room, the electric blower is electrically connected power supply unit.Electronic drum
Blower starts, and negative pressure is formed in electric blower room, is drawn so that generating suction at sweep-up pipe convenient for the absorption to dust
Dust enter in dust bag and collect.
Further, bag shaped structure is made by the material with aeration in the dust bag.It is intended that do not influence dust and
Exhaust.
Further, the power supply unit includes battery, and the battery is electrically connected photovoltaic solar panel.To reduce energy
Consumption, electric power are provided by solar energy.
