Abstract
Description
本新型關於一種粒子偵測裝置，且特別關於一種可偵測空氣中粒子信息的粒子偵測裝置。 The present invention relates to a particle detecting device, and more particularly to a particle detecting device capable of detecting particle information in the air.
一般環境與職業環境中，有害性因子入侵人體最主要的途徑為經由呼吸而來。根據統計，90%的工業中毒來自呼吸。因此，勞動部擬修法將生物性因子納入作業環境監測的項目中。 In the general environmental and occupational environment, the most important way for harmful factors to invade the human body is through breathing. According to statistics, 90% of industrial poisoning comes from breathing. Therefore, the Ministry of Labor intends to amend the biological factors into the project of environmental monitoring.
生物氣膠是生物性危害因子(真菌、細菌、病毒等)藉由附著於空氣中的粉塵微粒而來。當這些生物氣膠進入人體肺臟組織及其內不斷地循環時，這些空氣污染物可快速地經由呼吸作用造成人體呼吸器官及全身性的傷害。 Biogas gels are biological hazards (fungi, bacteria, viruses, etc.) that come from dust particles attached to the air. When these biogas gels enter the human lung tissue and circulate continuously, these air pollutants can quickly cause respiratory and systemic damage to the human body through respiration.
決定人體危害程度的主要關鍵因素與生物氣膠之粒徑大小有相當大的關係。當生物氣膠粒徑的大小不同，其在呼吸系統沉積的位置也不同。粒徑大小介於在2.5μm-10μm可以通過鼻腔的過濾而排除。至於可呼吸性與不可呼吸性的粒徑分界通常在5μm，並以重力沉積的方式被吸入而沉積在人體的呼吸道。 The main key factors determining the degree of human hazard have a considerable relationship with the size of the biogas gel. When the size of the biogas gel is different, it is also different in the location of the respiratory system deposition. Particle sizes ranging from 2.5 μm to 10 μm can be excluded by filtration through the nasal cavity. As for the respirability and non-respirability, the particle size boundary is usually 5 μm, and is inhaled by gravity deposition to deposit in the respiratory tract of the human body.
小於5μm的粒子會到達下呼吸道，而大於3μm之氣膠容易於支氣管 沈積。小於3μm之氣膠則容易於肺泡區沈積。由於生物性氣膠具有生物性，且大多數真菌孢子的粒徑大小介於2μm-10μm。換言之，這些粒子容易穿透人類的下呼吸道，進而導致感染，並對人體健康構成威脅。 Particles smaller than 5 μm will reach the lower respiratory tract, while gas gels larger than 3 μm are easier for the bronchus Deposition. A gas gel of less than 3 μm is easy to deposit in the alveolar region. Since bio-gas gels are biological, most fungal spores have a particle size ranging from 2 μm to 10 μm. In other words, these particles easily penetrate the lower respiratory tract of humans, which in turn leads to infection and poses a threat to human health.
因此，如果能夠設計出一種方便偵測空氣中粒子大小的裝置，並且將其偵測結果即時傳送給偵測人員，特別是涉及放在不同地點的多個偵測裝置的資訊整合，將能對於環境狀態監控提供有效積極的貢獻。 Therefore, if it is possible to design a device that can easily detect the particle size in the air and transmit the detection result to the detection personnel in real time, especially the information integration involving multiple detection devices placed in different locations, Environmental status monitoring provides an effective and positive contribution.
根據本創作的一個實施例，提供一種粒子偵測裝置，用於測定一待測空氣中粒子的分佈情況。這個粒子偵測裝置包括至少一過濾結構、空氣導道、至少一雷射探頭，以及一處理電路。 According to an embodiment of the present invention, a particle detecting device for determining the distribution of particles in an air to be tested is provided. The particle detecting device includes at least one filter structure, an air channel, at least one laser probe, and a processing circuit.
這裏提到的至少一過濾結構具有多數預定孔徑的空洞，可供小於該預定孔徑的粒子通過。空氣導道則透過幫浦等方式，將該待測空氣導流經該至少一過濾結構。為了過濾出不同粒徑的粒子，這個粒子偵測裝置可以具有多個不同預定孔徑的過濾結構。舉例來說，這些過濾結構可以是具有均勻孔洞的金屬篩選階層。 The at least one filter structure referred to herein has a plurality of voids of a predetermined pore size for passage of particles smaller than the predetermined pore size. The air channel guides the air to be tested through the at least one filtering structure through a pump or the like. In order to filter out particles of different particle sizes, the particle detecting device may have a plurality of filtering structures of different predetermined pore sizes. For example, these filter structures can be metal screening levels with uniform holes.
例如，每一階具有400個孔洞，而每階的孔徑為0.25mm、0.35mm、0.53mm、0.71mm、0.91mm、1.18mm。在流量28.3公升/分鐘之下之截取之截取粒徑分別7.0、4.7、3.3、2.1、1.1及0.65μm。在實作中，這個粒子偵測裝置可以用慣性衝擊器(inertial impactor)原理來設計。 For example, each step has 400 holes, and the aperture of each step is 0.25 mm, 0.35 mm, 0.53 mm, 0.71 mm, 0.91 mm, 1.18 mm. The intercepted particle sizes taken at a flow rate of 28.3 liters/min were 7.0, 4.7, 3.3, 2.1, 1.1, and 0.65 μm, respectively. In practice, this particle detection device can be designed using the principle of an inertial impactor.
所謂慣性衝擊器的原理，主要是利用微粒的空氣氣動力特性，來收集微粒。當含有微粒的空氣從噴嘴中噴出，碰到下方的收集板或衝擊板等接收器時，進而流線幾乎突然彎曲90度時，氣流中具有足夠慣性的微粒無法跟隨流線彎曲而衝擊在衝擊板上，而慣性較小的微粒比較能跟隨流線 彎曲，不會被衝擊板所收集。藉此，可以在衝擊器上收集不同孔徑的粒子進行進一步的分析。例如，在衝擊器上安置培養皿，對於粒子進行生物培養微生物或是利用顯微鏡、光譜儀等儀器對於所蒐集的樣本進行分析，進而取得相關的粒子信息。 The principle of the so-called inertial impactor is mainly to collect the particles by utilizing the aerodynamic characteristics of the particles. When the air containing the particles is ejected from the nozzle and hits the receiver such as the collecting plate or the impact plate below, and the flow line is almost suddenly bent by 90 degrees, the particles having sufficient inertia in the air flow cannot bend along the flow line and impact the impact. On the board, particles with less inertia can follow the streamline Bent, not collected by the impact plate. Thereby, particles of different pore sizes can be collected on the impactor for further analysis. For example, a culture dish is placed on the impactor, the microorganism is cultured for the particles, or the collected sample is analyzed by an instrument such as a microscope or a spectrometer to obtain related particle information.
除了上面說的元件，這個粒子偵測裝置的雷射探頭可用於偵測通過對應之該至少一過濾結構之該待測空氣中之粒子相關信息。雷射探頭可透過雷射光遮斷效應來計算粒徑與粒子數量。對應的處理電路則與該雷射探頭連接，計算出出該粒子相關信息。為了能即時傳送相關信息，這個粒子偵測裝置也可以配置Wi-Fi等網路介面，將該粒子相關信息傳送到一網路。 進而觀測人員可以直接存取這個粒子偵測裝置的粒子相關信息，或是這個網路介面將信息登載在網路上的資料庫，觀測人員則透過存取此資料庫即時取得所需信息，或進行相關的資料處理與統計分析。 In addition to the elements described above, the laser probe of the particle detecting device can be used to detect particle related information in the air to be tested passing through the corresponding at least one filter structure. The laser probe can calculate the particle size and the number of particles by the laser light blocking effect. A corresponding processing circuit is connected to the laser probe to calculate the particle related information. In order to transmit relevant information in real time, the particle detecting device can also be configured with a network interface such as Wi-Fi to transmit the particle related information to a network. In turn, the observer can directly access the particle-related information of the particle detecting device, or the network interface can display the information in the database on the network, and the observer can obtain the required information by accessing the database, or perform the information. Related data processing and statistical analysis.
除此之外，因應不同的應用需求，例如需要同時檢測許多地點的空氣品質，這些粒子偵測裝置可以設置在不同的地點。並且，在這些粒子偵測裝置中可以設置GPS等定位裝置。處理電路可以將定位電路所定出的地理位置，連同偵測導的粒子相關信息傳送到網路。因此，除了透過接收器上培養皿進行相關的生物檢測培養分析，也可以處理即時大量的信息，做適當即時的回應。 In addition, these particle detection devices can be placed at different locations in response to different application needs, such as the need to simultaneously detect air quality in many locations. Further, a positioning device such as a GPS can be provided in these particle detecting devices. The processing circuit can transmit the geographical location determined by the positioning circuit, together with the detected particle related information, to the network. Therefore, in addition to the relevant bioassay culture analysis through the Petri dish on the receiver, it is also possible to process an instant large amount of information and make an appropriate immediate response.
舉例來說，觀測培養皿並不容易知道上面的微生物是集中在什麼時間點出現。但如果有雷射探頭跟通訊的功能，觀測人員可以檢測何時具有異常狀況，並進而規劃行程，更有效地找出污染源頭的所在。 For example, observing a petri dish is not easy to know at what point in time the above microorganisms are concentrated. However, if there is a laser probe and communication function, the observer can detect when there is an abnormal situation, and then plan the itinerary to find out more effectively the source of the pollution.
這些過濾結構跟對應的雷射探頭可以做成模組，以層層疊接的方式加以組裝。這樣便構成多級的粒子偵測儀器。 These filter structures and corresponding laser probes can be made into modules and assembled in layers. This constitutes a multi-level particle detection instrument.
透過上述的粒子偵測裝置，觀測人員可以快速有效的取得所需的信 息，並即時進行因應，例如發布警報。此外，由於信息可以傳送到雲端進行處理，觀測人員進而可透過各種大數據的資料分析技巧，更有效地找出各種有價值的信息。例如，找出某些位置、某些粒子跟某些疾病之間的關聯。 Through the above particle detection device, the observer can quickly and efficiently obtain the required letter. Interest, and respond immediately, such as issuing an alert. In addition, because information can be transmitted to the cloud for processing, observers can use various data analysis techniques of big data to more effectively find out valuable information. For example, find out the association between certain locations, certain particles, and certain diseases.
因此，這樣的粒子偵測裝置達成了過去沒有的便利性與彈性。除了仍然可以用傳統的方式取得樣本進行進一步的精密分析，使用同一組偵測機器即可達到即時監控的功能，對於空氣污染防治與環境分析提供了重大的助益與貢獻。 Therefore, such a particle detecting device achieves convenience and flexibility that have not been achieved in the past. In addition to the traditional method of obtaining samples for further precision analysis, the same set of detection machines can be used to achieve real-time monitoring functions, which provides significant benefits and contributions to air pollution prevention and environmental analysis.

請參照圖1。圖1示範根據本創作的一個實施例，提供一種粒子偵測裝置，用於測定一待測空氣中粒子的分佈情況。這個粒子偵測裝置包括三個過濾結構101、111、121、空氣導道、三個雷射探頭104、114、124，以及一處理電路。在這個例子中，處理電路包括處理器15與通訊模組16。箭頭表示空氣導道造成的空氣流動路徑。空氣導道可以用不同的結構設計，包括提供推力的幫浦，以及導引空氣流過預定路徑的相關管路結構。 Please refer to Figure 1. Figure 1 illustrates an embodiment of the present invention for providing a particle detecting device for determining the distribution of particles in an air to be tested. The particle detecting device includes three filter structures 101, 111, 121, an air channel, three laser probes 104, 114, 124, and a processing circuit. In this example, the processing circuit includes a processor 15 and a communication module 16. The arrows indicate the air flow path caused by the air channel. The air guides can be designed in different configurations, including a pump that provides thrust and associated piping structures that direct air through a predetermined path.
這三個過濾結構101、111、121具有多數預定孔徑的空洞，可供小於該預定孔徑的粒子通過。空氣導道則透過幫浦等方式，將該待測空氣導流經這些過濾結構101、111、121。為了過濾出不同粒徑的粒子，這個粒 子偵測裝置可以具有多個不同預定孔徑的過濾結構。舉例來說，這些過濾結構可以是具有均勻孔洞的金屬篩選階層。 The three filter structures 101, 111, 121 have a plurality of voids of a predetermined pore size through which particles smaller than the predetermined pore size can pass. The air channel guides the air to be tested through the filter structures 101, 111, 121 through a pump or the like. In order to filter out particles of different particle sizes, this grain The sub-detection device can have a plurality of filter structures of different predetermined apertures. For example, these filter structures can be metal screening levels with uniform holes.
例如，每一階具有400個孔洞，而每階的孔徑為0.25mm、0.35mm、0.53mm、0.71mm、0.91mm、1.18mm。在流量28.3公升/分鐘之下之截取之截取粒徑分別7.0、4.7、3.3、2.1、1.1及0.65μm。在實作中，這個粒子偵測裝置可以用慣性衝擊器(inertial impactor)原理來設計。 For example, each step has 400 holes, and the aperture of each step is 0.25 mm, 0.35 mm, 0.53 mm, 0.71 mm, 0.91 mm, 1.18 mm. The intercepted particle sizes taken at a flow rate of 28.3 liters/min were 7.0, 4.7, 3.3, 2.1, 1.1, and 0.65 μm, respectively. In practice, this particle detection device can be designed using the principle of an inertial impactor.
所謂慣性衝擊器的原理，主要是利用微粒的空氣氣動力特性，來收集微粒。當含有微粒的空氣從噴嘴中噴出，碰到下方的收集板或衝擊板等接收器102、112、122時，進而流線幾乎突然彎曲90度時，氣流中具有足夠慣性的微粒無法跟隨流線彎曲而衝擊在衝擊板上，而慣性較小的微粒比較能跟隨流線彎曲，不會被衝擊板所收集。藉此，可以在衝擊器上收集不同孔徑的粒子進行進一步的分析。例如，在衝擊器上安置培養皿103、113、123，對於粒子進行生物培養微生物或是利用顯微鏡、光譜儀等儀器對於所蒐集的樣本進行分析，進而取得相關的粒子信息。 The principle of the so-called inertial impactor is mainly to collect the particles by utilizing the aerodynamic characteristics of the particles. When the air containing the particles is ejected from the nozzle and hits the receivers 102, 112, 122 such as the lower collecting plate or the impact plate, and the flow line is almost suddenly bent by 90 degrees, the particles having sufficient inertia in the air flow cannot follow the flow line. Bending and impacting on the impact plate, while particles with less inertia can follow the streamline and are not collected by the impact plate. Thereby, particles of different pore sizes can be collected on the impactor for further analysis. For example, the culture dishes 103, 113, and 123 are placed on the impactor, the microorganisms are cultured for the particles, or the collected samples are analyzed by instruments such as a microscope or a spectrometer to obtain related particle information.
除了上面說的元件，這個粒子偵測裝置的雷射探頭104、114、124可用於偵測通過對應之該至少一過濾結構之該待測空氣中之粒子相關信息。雷射探頭104、114、124可透過雷射光遮斷效應來計算粒徑與粒子數量。對應的處理電路則與該雷射探頭104、114、124連接，計算出出該粒子相關信息。 In addition to the elements described above, the laser probes 104, 114, 124 of the particle detecting device can be used to detect particle related information in the air to be tested that passes through the at least one filter structure. The laser probes 104, 114, 124 can calculate the particle size and the number of particles by the laser light blocking effect. Corresponding processing circuits are connected to the laser probes 104, 114, and 124 to calculate the particle related information.
請參考圖2，其示範雷射探頭偵測粒子的系統示意圖。首先，雷射探頭21可發射雷射光到具有待測空氣的區域，這些雷射光會被空氣中的粒子20部分遮斷，進而在感測器220上呈現對應的結果。這個結果可以是數位影像，也可以是其他的電子信息。處理電路221對於這些偵測結構進行分析與計算，取得所需的粒子信息。這些粒子信息透過通訊電路222，例如 各種有線或無線網路傳送到網路23，進而觀測人員可透過監控系統24或是電腦、手機或平板等終端設備25即時取得相關的信息，並且進行所需的分析跟因應操作。 Please refer to FIG. 2, which illustrates a system diagram of a laser probe detecting particles. First, the laser probe 21 can emit laser light to an area having air to be tested, which is partially blocked by the particles 20 in the air, thereby presenting corresponding results on the sensor 220. This result can be a digital image or other electronic information. The processing circuit 221 analyzes and calculates these detection structures to obtain desired particle information. These particle information is transmitted through the communication circuit 222, for example Various wired or wireless networks are transmitted to the network 23, so that the observer can instantly obtain relevant information through the monitoring system 24 or the terminal device 25 such as a computer, a mobile phone or a tablet, and perform required analysis and operation.
為了能即時傳送相關信息，這個粒子偵測裝置也可以配置Wi-Fi等網路介面，例如圖1中的通訊模組16，將該粒子相關信息傳送到一網路。進而觀測人員可以直接存取這個粒子偵測裝置的粒子相關信息，或是這個網路介面將信息登載在網路上的資料庫，觀測人員則透過存取此資料庫即時取得所需信息，或進行相關的資料處理與統計分析。 In order to transmit relevant information in real time, the particle detecting device can also be configured with a network interface such as Wi-Fi, such as the communication module 16 in FIG. 1, to transmit the particle related information to a network. In turn, the observer can directly access the particle-related information of the particle detecting device, or the network interface can display the information in the database on the network, and the observer can obtain the required information by accessing the database, or perform the information.

除此之外，因應不同的應用需求，例如需要同時檢測許多地點的空氣品質，這些粒子偵測裝置可以設置在不同的地點。並且，在這些粒子偵測裝置中可以設置GPS等定位裝置。處理電路可以將定位電路所定出的地理位置，連同偵測導的粒子相關信息傳送到網路。因此，除了透過接收器上培養皿進行相關的生物檢測培養分析，也可以處理即時大量的信息，做適當即時的回應。 In addition, these particle detection devices can be placed at different locations in response to different application needs, such as the need to simultaneously detect air quality in many locations. Further, a positioning device such as a GPS can be provided in these particle detecting devices. The processing circuit can transmit the geographical location determined by the positioning circuit, together with the detected particle related information, to the network. Therefore, in addition to the relevant bioassay culture analysis through the Petri dish on the receiver, it is also possible to process an instant large amount of information and make an appropriate immediate response.

請參照圖3，其例示一種疊接的模組化粒子偵測裝置。在這個粒子偵測裝置中，有六個針對不同粒徑設計的模組31、32、33、34、35、36。這些模組31、32、33、34、35、36有自己的接收器與雷射探頭371、372、373、374、375、376。這些雷射探頭371、372、373、374、375、376取得的信息可以透過Wi-Fi模組39傳送到其他的電子裝置或是本地網路或是網際網 路。待測空氣301依序流經各模組的過濾結構，最後由導管38流出。各個模組的雷射探頭提供對應的粒子信息，整合處理後傳給觀測人員進行處理。 Please refer to FIG. 3, which illustrates a stacked modular particle detecting device. In this particle detecting device, there are six modules 31, 32, 33, 34, 35, 36 designed for different particle sizes. These modules 31, 32, 33, 34, 35, 36 have their own receiver and laser probes 371, 372, 373, 374, 375, 376.
