DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an overall configuration for monitoring a contamination state of a filter according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the filter condition monitoring apparatus 101 can determine a contamination state for each filter corresponding to a plurality of filters built in the purification apparatus. The filter condition monitoring apparatus 101 can determine whether filter replacement or filter sterilization is necessary depending on the contamination state of the determined filter. Thereafter, the filter condition monitoring apparatus 101 may transmit a message or an image to the user or the manager so that the corresponding filter can be replaced or sterilize the filter region of the filter contaminated by the source.

More specifically, although not shown in FIG. 1, the filter condition monitoring apparatus 101 may include an image collection command delivery unit, an image information reception unit, an image information determination unit, and a sterilization processing command delivery unit.

The image acquisition command transfer unit may transmit an image acquisition command to the contamination filter processing unit 104 to monitor the Nth filter 105 among the plurality of filters embedded in the purification apparatus. More specifically, the image collection command transfer unit may select the Nth filter 105 to check the contamination state of the filter among a plurality of filters built in the purification apparatus. The image collection command delivery unit may deliver an image collection command for monitoring the selected Nth filter 105 to the contamination filter processing unit 104. [ Here, the image acquisition command transfer unit may transmit the image acquisition command to the guide rail controller 102 that manages the guide rail 103 connected to the contamination filter processing unit 104.

For example, the guide rail controller 102 controls the contamination filter processing device 104 to move along the guide rail 103 in accordance with a predetermined monitoring period or a user / manager monitoring command to check the contamination state of the filter .

The guide rail controller 102 is connected to the contamination filter processing unit (not shown) connected to the guide rail 103 to the point where the Nth filter 105 in the purifier unit is located in order to perform monitoring in accordance with the image collection command transmitted from the image collection command delivery unit 104 to move. Then, the guide rail controller 102 can transmit the image collection command transmitted from the image collection command delivery unit to the contamination filter processing unit 104. [ For example, the guide rail controller 102 may transmit a 'Control Sign' corresponding to the image acquisition command to the contamination filter processing unit 104.

The contamination filter processing unit 104 may collect image information about the Nth filter 105 disposed at a point moved within the purifier according to the guide rails 103. [ The image information may include a first real image and a first fluorescence image for the Nth filter 105. To this end, the contamination filter processing unit 104 may output the light source to the Nth filter disposed in the purifier corresponding to the image collection command received from the filter condition monitoring apparatus 101. [ Here, the light source may include a white light source and a multi-wavelength light source, and a more detailed structure of the light source will be described with reference to FIG.

The contamination filter processing unit 104 may collect the first real image and the first fluorescence image related to the contaminated state of the Nth filter 105 from which the light source is output. The contamination filter processing unit 104 transfers the first actual image and the first fluorescence image collected by the guide rail controller 102 and can maintain the standby state until the next command is transmitted from the guide rail controller 102 . Then, the guide rail controller 102 can transmit the first real image and the first fluorescent image received from the contamination filter processing unit 104 to the filter condition monitoring apparatus 101.

The filter condition monitoring apparatus 101 can receive the first actual image and the first fluorescence image collected from the guide rail controller 102 through the contamination filter processing unit 104. [ The filter condition monitoring apparatus 101 analyzes the types of contaminants adsorbed on the filter by comparing and analyzing the received first real image and the first fluorescent image, , Whether cleaning or sterilization is necessary.

In addition, when the filter sterilization is required due to a contamination source, the filter condition monitoring apparatus 101 can sterilize the contaminated area of the contaminated filter through the ultraviolet sterilizing light source based on the image information. In other words, the filter condition monitoring apparatus 101 determines whether sterilization by a microorganism is necessary in the contamination source, and outputs the ultraviolet sterilizing light source to the filter using the contamination filter processing unit 104 according to the determined result, It is possible to sterilize the microorganisms adsorbed on the microorganisms.

Here, the contamination filter processing apparatus 104 adjusts the wavelength (UV-A, UV-B, UV-C region), intensity and sterilization time of the sterilizing light source according to the kind and density of the microorganisms adsorbed in the filter, Fine sterilization can be performed. In addition, the control can be adjusted based on the information obtained through the data comparison and analysis based on the image information and the ultraviolet sterilization characteristic data of the microorganisms stored in the memory.

In addition, when filter replacement is required, the filter condition monitoring apparatus 101 may transmit replacement information for a filter that is required to be replaced to a user or an administrator to the user terminal.

2 is a view showing a detailed configuration of a contaminated filter treating apparatus according to an embodiment.

Referring to FIG. 2, the contaminated filter processing apparatus 201 is built in a purifier and is movable along a guide rail corresponding to a filter to be monitored. The first actual image and the second actual image 1 Fluorescence images can be collected. At this time, the contamination filter processing apparatus 201 moves according to a predetermined monitoring cycle and a user or an administrator's command according to a guide rail, and collects image information on a plurality of filters built in the purification apparatus.

For example, when it is desired to check the contamination state of the Nth filter, the filter condition monitoring apparatus may transmit an image collection command to the guide rail controller for checking the contamination state of the Nth filter. The guide rail controller transfers the received image acquisition command to the contamination filter processing apparatus 201 and the contamination filter processing apparatus 201 can move to a position where the contamination state of the Nth filter can be confirmed along the guide rail. Thereafter, the contamination filter processing unit 201 outputs a light source to the filter, collects the first real image and the first fluorescent image for the filter, and returns to the standby state when the image collection is completed, and waits for receiving the next command .

To this end, the contamination filter treatment apparatus 201 may be located within the frame 206 to move its position within the purifier. This may be to isolate the contaminated filter treatment apparatus 201 from external contaminants. Then, the frame 206 is connected to the guide rail, and the position can be moved to monitor a plurality of filters embedded in the purifier. When the first actual image and the first fluorescence image of the filter are collected by the contamination filter processing unit 201 according to the image collection command, the frame 206 can open / close the cover formed on one side.

In other words, the light source may include a white light source 205 and a multi-wavelength light source 204. The white light source 205 may be a light source for obtaining a first actual image of the filter. The multi-wavelength light source 204 may be a light source for inducing fluorescence emission of microorganisms to acquire a first fluorescence image, and may have a wavelength in a region close to ultraviolet rays or ultraviolet rays.

The image acquisition device 202 may acquire a first real image and a first fluorescence image of a filter to be monitored. For example, the image acquisition device 202 may include an apparatus or device for acquiring images such as an image sensor, a photodetector, and a camera.

The sterilizing light source 203 may be an ultraviolet light source for sterilizing the microorganisms adsorbed by the filter when the filter is contaminated by a contaminant formed by microorganisms. In one example, the sterilizing light source 203 may be an ultraviolet light source in the UV-A, UV-B, and UV-C regions.

Here, the present invention may include an optical lens 207 for outputting a light source with a filter having a large area in consideration of an area of a filter and collecting an image. In other words, by disposing the optical lens 207 on the front surface of the light source and the image acquisition device 202 to collect more accurate image information from the filter having a large area, the output range of the light source output to the filter and the image acquisition Area can be expanded. For example, the present invention can be applied to the front surface of a white light source 205, a sterilization source 203 and a multi-wavelength light source 204, as shown in FIG. 2, with optical lenses 207 ', 207 ", 207' Respectively. The optical lens 207 may be disposed on the front surface of the image acquisition device 202 according to the present invention.

Accordingly, since the light source is output to a wide area of the filter through the optical lens 207 and the image can be collected, the image information can be collected more effectively.

Each component constituting the pollution filter processing apparatus 201 can be disposed so as to be opposed to or viewed obliquely from an object to be monitored, and the position, arrangement and number (number) between the respective components can be varied And the like.

In addition, the decontamination filter processing apparatus 201 may perform a collecting operation for collecting the first real image and the first fluorescent image through the image acquiring device 202 while turning on the white light source and the multi-wavelength light source, respectively .

The guide rails can be extended to various forms such as straight lines, curved lines, and lungs depending on the internal structure of the purifying device and the purifying system. In addition, the pollution filter processing apparatus can perform a plurality of filter state monitoring and sterilization by moving inside complex purification apparatus and purification system along guide rails that can be expanded in various forms.

Each of the graphs shown in Fig. 4 shows emission wavelengths according to excitation wavelengths for each of tryptophan, nicotinamide adenine dinucleotides (NADH) and riboflavin (Riboflavin). Here, tryptophan is one of the protein-constituting amino acids, nicotinamide adenine dinucleotide (NADH) is a non-protein necessary for the activity of an intracellular enzyme protein, and riboflavin can be a vitamin B complex.

Fluorescence microbes including these are excited by high-energy ultraviolet or near-blue wavelengths (280 to 450 nm), and the visible light region (350 to 520 nm) of blue and green wavelength regions with relatively low energy Emitting layer.

Therefore, the present invention can collect fluorescence images by the microorganisms adsorbed on the filter using the fluorescence reaction characteristics depending on the presence or absence of numerous microorganisms, bacteria, pathogens, etc. containing the biological components and the degree of distribution within the filter , And analysis can be performed. The present invention can also analyze the species and density of microorganisms through the wavelength and intensity analysis of the excitation-emission spectrum.

FIG. 5 is a graph showing excitation-emission spectrum of biological components and cells showing fluorescence characteristics according to one embodiment.

The graph shown in FIG. 5 shows the fluorescence characteristics of Tryptophan, NADH and Riboflavin as well as Staphylococcus aureus (S. aureus), Bacillus subtilis (B. subtilis) and Pseudomonas fluorescens fluorescence: P. fluorescens), Yersinia pestis (Y. pestis), Micococcus lysodeikticus (M. lysodeikticus), Clostridium perfrignens (C. perfrignens) and the like. Here, Staphylococcus aureus can be a cause of diseases such as food poisoning, skin inflammation, otitis media, cystitis and the like. Bacillus, Pseudomonas fluorescens, Pest bacteria, M. lysodeikticus and C. perfrignens may be various bacterial cells widely distributed in nature such as soil, hay, and dust.

Here, it can be seen that the fluorescence characteristics of various components and cells are different from each other through the graph showing the emission intensity normalized by the excitation-emission spectrum and the intensity of the excitation light for the causative bacteria of various diseases and various bacterial cells. From this, it can be seen that the present invention can grasp the kinds of microorganisms through the excitation-emission spectrum analysis of the fluorescent microorganisms and increase the measurement accuracy by increasing the fluorescence microbe emission intensity through the adjustment of the intensity of the excitation light source .
