本發明係關於一種無線空氣品質監控系統,特別是一種依據該等感測傳送板之電氣特性以及頻率響應特性,判斷該等感測傳送板所量測之污染源種類,進而調整該等污染源之濃度值之量測範圍之無線空氣品質監控系統。 The invention relates to a wireless air quality monitoring system, in particular to determining the types of pollution sources measured by the sensing transmission boards according to the electrical characteristics and frequency response characteristics of the sensing transmission boards, and thereby adjusting the concentration of the pollution sources. A wireless air quality monitoring system that measures the range of values.
在目前每人每天約有80%至90%的時間處於室內環境中(包括在住家、辦公室或其他建築物內),室內空氣品質的良窳,直接影響工作品質及效率,因此室內空氣污染物對人體健康影響應當受到重視。近年來室內空氣健康危害的議題逐漸被大家所重視,尤其是最近二、三十年來大眾生活型態的改變,使得人們在密閉的居住空間或是辦公空間裏享受空調系統帶來的舒適便利之餘,「病態建築物症候群」(Sick Building Syndrome)也應運而生。在密閉的建築物內,如果室內通氣量不足時,污染物就容易蓄積而導致室內空氣品質惡化。 At present, about 80% to 90% of the time per person per day is in an indoor environment (including in a home, office or other building). The quality of indoor air quality directly affects work quality and efficiency, so indoor air pollutants The impact on human health should be taken seriously. In recent years, the issue of indoor air health hazards has gradually been valued by everyone. In particular, the changes in the way of life in the past two or three decades have made people enjoy the comfort and convenience of air-conditioning systems in confined living spaces or office spaces. Yu, "Sick Building Syndrome" (Sick Building Syndrome) also came into being. In a closed building, if the indoor ventilation is insufficient, the pollutants will easily accumulate and the indoor air quality will deteriorate.
另外,室外的污染物也有可能是影響室內空氣品質的因素,包括戶外汽機車、工廠排放的廢氣,或是因中央空調冷氣系統的外氣進氣口或濾網未定期清理而孳生的微生物等。台灣地處亞熱帶,屬於長年潮濕高溫的氣候型態,黴菌及細菌尤其容易孳生,因此必須更注意空調通風系統的定期維護。室內空氣品質對於經常在室內的兒童、孕婦、老人和慢性病人更是特別重要。 In addition, outdoor pollutants may also be factors affecting indoor air quality, including outdoor steam locomotives, exhaust emissions from factories, or microorganisms that are generated by the external air intake or filter screen of the central air-conditioning system. . Taiwan is located in the subtropical zone and belongs to the climatic pattern of long-term humid and high temperature. Molds and bacteria are particularly prone to twinning, so it is necessary to pay more attention to the regular maintenance of air-conditioning ventilation systems. Indoor air quality is especially important for children, pregnant women, the elderly and chronic patients who are often indoors.
有關空氣品質無線監測系統研究包括監測硬體和軟體設備,其功能為 將硬體介面的整合,藉由監測軟體加以配合的系統,其中重點工作內容包括以下四項:1.氣體感測器整合;2.資料擷取模組及監測軟體開發;3.無線通訊模組信號傳輸;以及4.空氣品質無線監測平台架構設計。 Research on air quality wireless monitoring systems includes monitoring hardware and software devices, the function of which is The integration of the hardware interface, through monitoring the software to cooperate with the system, the key work includes the following four items: 1. gas sensor integration; 2. data acquisition module and monitoring software development; 3. wireless communication mode Group signal transmission; and 4. Air quality wireless monitoring platform architecture design.
上述四項系統即完成室內空氣品質無線監測模組,並應用於實地進行長時間連續監測且設計動態指標系統提供使用者即時瞭解目前所處建築物之室內室外空氣品質現況,由於使用單點量測方式,並未考量到室內環境地區大小,因此可能無法表達某地區室內空氣品質指標數據分析,加上感測器種類是固定而不可更換,因此僅能感測一種污染源,且無法預測未來之空氣品質,而不利於監測人員使用。 The above four systems complete the indoor air quality wireless monitoring module, and are applied to the field for long-term continuous monitoring and design dynamic indicator system to provide users with instant access to the current indoor and outdoor air quality status of the current building, due to the use of single point quantities. The measurement method does not consider the size of the indoor environment. Therefore, it may not be able to express the analysis of indoor air quality indicators in a certain area. In addition, the sensor type is fixed and cannot be replaced, so it can only sense one source of pollution and cannot predict the future. Air quality is not conducive to the use of monitoring personnel.
