Abstract
The invention relates to a flue dust particle vision sampling system and a monitoring method thereof, wherein, an image sensor and an illumination light source are arranged at the port of a flue gas discharge channel of a flue reflecting conditions of dust particles discharged to the air, and the image sensor acquires the flue dust image information in the flue and enters a computer for processing data through an acquisition card, so the system can realize the on-line real-time detection to flue gas discharge and provide the powerful gist for controlling the atmospheric pollution.
Description
Technical field
The present invention relates to a kind of detection sampling system, particularly a kind of visual sense sampling system of air flue soot dust granule.
Background technology
Along with the mankind to the going deep into of the understanding of smoke contamination harmfulness, people have higher requirement also corresponding various emission standards and the rules formulated of national governments to the concentration and the particle diameter of the flue dust of each pollution source discharging.The control of gross contamination emission is a complicated system engineering, and determines that the discharge capacity of pollutant is the basis of overall control.The measurement of the discharge capacity of pollutant needs certain detection means, and testing result is to weigh direct, the most convictive voucher that respectively pollutes unit discharge.For flue dust control, record smoke dust discharge concentration and can further calculate the total emissions level of emission source within a certain period of time.Therefore, the development on-line continuous is measured the instrument system of soot dust granule thing particle diameter and concentration, and the control atmospheric pollution is had very important meaning.
The sampling of air flue soot dust granule is the primary part that realizes that the soot emissions online in real time detects.Therefore, for the air flue soot dust on-line monitoring system that adopts computer vision technique, clearly to obtain the image information of flue be system's key of success to high-quality.
Flue is an airtight environment, its inwall adhesion person soot dust granule.If adopt common means pickup image, because the soot dust granule that flows in as a setting flue inwall and the flue has same color, what therefore obtain is monochrome image without any content, can't therefrom differentiate or identify soot dust granule.
Summary of the invention
The present invention be directed to the existing problem that lacks effective air flue soot dust granule Image Acquisition and monitoring technology, a kind of vision method of sampling of air flue soot dust granule has been proposed, clearly high-quality obtains the image information of flue, has reflected chimney of equal valuely and finally has been discharged into soot dust granule situation in the atmosphere.
Technical scheme of the present invention is: a kind of visual sense sampling system of air flue soot dust granule, comprise the flue and the fume emission passage that can reflect the soot dust granule situation that enters in the atmosphere, it is characterized in that also comprising imageing sensor, lighting source, heat insulation air curtain curtain, image pick-up card, computing machine, imageing sensor and lighting source are installed in the ipsilateral opening part of fume emission passage, heat insulation air curtain curtain wherein is installed in the middle of imageing sensor and the lateral opening place, prevent and remove window surface and adhere to soot dust granule, the lighting source setting angle makes the horizontal pickup axis of the optical axis of lighting source and imageing sensor intersect at the centre position of flue, the focusing surface that guarantees imageing sensor has enough illumination, and the flue dust picture information that imageing sensor obtains in the flue is sent in the computing machine by image pick-up card.
Beneficial effect of the present invention is: the present invention realizes that the soot emissions online in real time detects, and provides strong foundation to the control atmospheric pollution.
Description of drawings
Fig. 1 is the vision method of sampling synoptic diagram of air flue soot dust granule of the present invention.
Embodiment
The vision method of sampling synoptic diagram of air flue soot dust granule of the present invention as shown in Figure 1, flue 8 is seals of a dark, so images acquired must adopt the caesium lamp to produce uniform directional light herein by certain light source 1.Imageing sensor 2 and lighting source 1 are installed in the lateral opening place of fume emission passage 8.Flue herein be the fume emission passage (boiler-＞electrostatic precipitator-＞flue-＞chimney) a part, it has reflected chimney of equal valuely and finally has been discharged into soot dust granule 4 situations in the atmosphere.Be the ambient temperature conditions that guarantees that imageing sensor can operate as normal, lateral opening at the fume emission passage of imageing sensor 2 correspondences is installed a heat insulation air curtain curtain 3, it adopts the high temperature of the isolated flue inside of heat-resisting high printing opacity quartz glass, air curtain curtain technology can prevent and remove window surface and adhere to soot dust granule, otherwise the laying dust that window surface produces can make the imageing sensor can not be clear even can't obtain the image of flue inside.When installation diagram image-position sensor 2 and lighting source 1, the optical axis 5 that makes lighting source and the horizontal pickup axis 7 of imageing sensor intersect at the centre position of flue, it is sample region 6, the position that light source is installed and the angle of inclined light shaft guarantee that the focusing surface of imageing sensor has enough illumination, but do not illuminate the background of imaging, can clearly obtain the flue dust picture information in the middle of the flue 8 like this.Can not satisfy requirement like this if install, soot dust granule is difficult to recognize on homochromy background so.Image pick-up card 9 is sent into computing machine after the image information of imageing sensor 2 is converted to digital form, and industrial computer 10 is with data storage and show, can also reach the control survey warning function by computer application software.
Industrial computer handles, shows that free defined parameters and setup parameter value generate chart to data by software, set ultimate value and report to the police, and formation can monitor dust concentration and the monitoring system of reporting to the police at any time, and the concrete monitoring of software operation steps of giving an example is as follows:
1, sets emission measurement program run zero-time;
2, set the setting of the smoke granularity limit, promptly alarm parameters is set;
3, the reduced parameter limit is provided with, and draws correlation curve;
4, the normal/abnormal indication of light source, light source just often are green, if become redness unusually, it is excessive that the expression light source may have been gone bad or light-source brightness is decayed, and need more change the bulb;
5, particle diameter (X-axis)-granule number (Y-axis) histogram shows;
6, data and curves shows, time-granularity (%) figure, transverse axis corresponding data writing time, the corresponding smoke granularity of the longitudinal axis;
7, alarming horn switch opens, smoke granularity will be sent chimes of doom greater than setting value;
8, print the alert data functional switch automatically and open, set the time span value of printing alert data automatically, promptly send the constantly forward and backward time span value of reporting to the police; Smoke granularity according to the automatic print data curve of setting of time value, shows to exceed standard value and time during greater than setting value.
Above setting operation can be set according to concrete needs are selected, to realize the function of on-line real time monitoring and warning.
