The automatic cleaning device is scientific and reasonable in design, and simple in structure, can effectively achieve automatic operation of window cleaning, and not only greatly lowers work force, but also avoids scratches in the window.
Description
Technical field
The utility model belongs to the video security monitoring field, especially a kind of auto cleaning system of anti-explosion surveillance camera form.
Background technology
Explosion-proof video camera belongs to the anti-explosion surveillance series products, be explosion-proof industry and monitoring trade in conjunction with product, the operation principle of explosion-proof video camera is suppress the generation of blast four key elements and accomplish that electric equipment products still work at high-risk environment, and four key elements of blast are respectively: 1. scene has imflammable gas, dust and mixture and forms finite concentration; 2. there is sufficient oxygen at scene with combustible generation combustion reaction; 3. on-the-spot have enough temperature can cause mixture in oxygen generation combustion reaction; 4. site space is assembled even explosion of finite concentration in the narrow and small heat short time that is enough to make after burning.
Known according to the working environment of explosion-proof video camera, for in dust and mixture monitoring environment are arranged, explosion-proof video camera must be equipped with viewing window cleaner, as rain brush or wiper etc., existing explosion-proof video camera all is provided with viewing window cleaner basically, the use of its viewing window cleaner is estimated manual control by staff in master-control room, if in monitoring environment visibility preferably under environment, such control method is simply effective, but more at dust, under the poor monitoring environment of visibility, if only cleaned by the artificial visually examine, must cause personnel's fatigue and clean the omission, so not only can affect the IMAQ quality of explosion-proof monitoring system, even can make its video monitoring function lose efficacy, there is again current viewing window cleaner generally to adopt rain brush or windscreen wiper, rain brush or wiper are mainly used in clean rainwater, it in explosion-proof environment, is mainly dust, rain brush or wiper are bad to the granule dust cleaning effect, and the scraping blade of rain brush or wiper is easily scraped and is damaged the form sheet in clean form.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of auto cleaning system of simple in structure, easy to operate anti-explosion surveillance camera form is provided.
Technical solutions of the utility model are achieved in that
A kind of automatic cleaning apparatus of anti-explosion surveillance camera form, comprise video acquisition device, viewing window cleaner, the motor for driving viewing window cleaner, visibility sensor and MCU, the input of described video acquisition device and visibility sensor is connected MCU, the output of MCU connects motor, and this motor drives viewing window cleaner to rotate.
And described viewing window cleaner comprises support, jet flexible pipe, hairbrush body, described support upper end is equipped with the hairbrush body, on this hairbrush body, is shaped with a plurality of ventholes, this venthole and the jet soft pipe connection be arranged in support.
And described venthole is two, and the vertical spacing setting.
Advantage of the present utility model and good effect are:
1, native system judges the form clean-up performance by the visibility numerical value of visibility sensor and video acquisition device collection is different, makes clean intelligent, the hommization of form.
2, the viewing window cleaner of native system adopts and be shaped with two ventholes on the hairbrush body, this two ventholes and jet soft pipe connection, thereby the small dust that will be attached to the form surface by the outside inject high pressure gas of jet flexible pipe dispels, and coordinate the swing of hairbrush can remove fast the dust on form surface.
3, the utility model design science is reasonable, simple in structure, effectively realizes the automation mechanized operation of clean form, guarantees the definition of monitored picture, not only greatly reduces the labour, and has avoided the form cut.
The accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is the structural representation of the utility model cleaning device;
Fig. 3 is control flow chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of automatic cleaning apparatus of anti-explosion surveillance camera form, as shown in the figure, comprise video acquisition device, viewing window cleaner, the motor for driving viewing window cleaner, visibility sensor and MCU, the input of described video acquisition device and visibility sensor is connected MCU, the output of MCU connects motor, and this motor drives viewing window cleaner to rotate.
In the present embodiment, described viewing window cleaner comprises support 3, jet flexible pipe 4, hairbrush body 1 as shown in Figure 2, described support upper end is equipped with the hairbrush body, vertically is shaped with two ventholes 2 on this hairbrush body, this venthole and the jet soft pipe connection be arranged in support.
Control flow chart of the present utility model is as shown in Figure 3:
Video acquisition device gathers video image (step 101) and sends to MCU to carry out image processing (step 102), calculate video image visibility numerical value B(step 103 by MCU), now visibility sensor is by the visibility numerical value A(step 105 detected) send to MCU(104), then A and B are compared and carry out difference calculating (A-B) (step 106), if the difference obtained is greater than the threshold values that native system arranges, MCU will judge that the cleanliness factor of video monitoring apparatus front end form is poor, it is the quality that form has affected the video acquisition device IMAQ, now MCU will send a signal to motor and make its running (step 107), motor will drive viewing window cleaner form will be cleaned to (step 108), if the difference obtained is less than the threshold values that native system arranges, MCU will judge that the cleanliness factor of video monitoring apparatus front end form is better, and form does not affect the quality of video acquisition device IMAQ, at this moment will return to step (step 104).
The utility model has the advantages of and be:
After motor obtains MCU unlatching control signal, the hairbrush of viewing window cleaner is swung, simultaneously to the jet flexible pipe inflation in support, the venthole that gases at high pressure are shaped with from the hairbrush body by jet flexible pipe is outwards jet, remove the granule dust on the form (not shown) by gases at high pressure, under synergy by hairbrush body and jet flexible pipe, not only effectively remove fast the granule dust that is attached to the form surface like this, also effectively avoided the form cut simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
