本計畫主要工作為提升空氣品質監測中心主機資訊安全防護功能、強化空氣品質系統資料處理功能、充實空氣品質資料庫內容，以強化空氣品質監測網資料中心系統於資訊安全、資料處理及資料完備等各面向的機能。 　　為避免網際網路使用者直接存取中心端資料庫伺服器資料，可能造成的資訊安全風險，本計畫建立與監測網資料隔離的資料發佈資料庫，並設計完備的資料發佈機制，以安全的方式進行內外網段空氣品質資料庫同步。此外，在使用者管理上，透過強化使用者登入安全管理、增加稽核功能、重新設計權限管理系統等設計，解決日益繁複系統權限管理需求。 　　為因應評估新一代空氣品質指標AQI對台灣得適用性，增加AQI空氣污染指標計算及報表功能，可計算小時、日、區域等AQI值並進行各項統計計算，並新增各式AQI相關報表。 　　為使系統具備空氣網站主題的風貌，重新設計網站風格，使網站風格呈現具環境保護概念的視覺效果。在改善使用者操作介面上，以重新設計的選單操作方式、單視窗的查詢介面、三項輸入選擇器及新設計的趨勢圖等使用者親和的設計，讓使用者操作更易上手。 　　署內的其他相關空氣監測站資料於本計畫中亦一併納入整合該共同網站入口，包括紫外線現況、世界各地空氣品質現況、Modis-衛星遙測影像、逆溫資料查詢、光化測站、光達站、鹿林山背景站、及超級測站等。 　　對於風向、風速、溫度、雨量、雨強、UVB、UVA、酸雨等氣象相關測項的資料驗證處理，分別依照其物理意義及統計需求，重新設計資料處理驗證程式，規劃儲存資料表，安排定期計算排程作業，與原始系統計算作業流程結合，定期產生特殊測項計算資料，提供空氣品質預報作業使用。 　　關於充實空氣品質資料工作分為三個方面，第一項為分析原儲存於PDP11系統，自民國71年至82年8月共19站16項之各監測項目之小時值備份資料，逐筆轉入空氣品質監測資料庫，轉入後的歷史資料可在系統環境下執行各項相關資料查詢、統計分析等功能，使資料庫涵蓋資料上溯至民國71年。第二項為匯入上一代空氣品質資料庫儀器校正資料，自82年9月迄93年共計11年的歷史校正資料，可和資料庫中的空氣品質歷史資料相對照，具極高的參考價值。第三項處理行動測站的資料，行動測站除了各監測項目監測資料外，還具有監測座標的資料屬性，於整合匯入中介伺服器的行動站資料後，透過署內地理資訊伺服器提供圖層資訊，將行動測站的監測位置及鄰近空品氣象、測站以地圖方式整合展示。

The major works of this project are improving the information security of sever of air quality monitoring center, reinforcing the process of system data of air quality, replenishing the database in content, to consolidate the functions of air quality monitoring network, data security , data processing and data completeness. 　　To avoid the internet users access data from the EMC server directly, may result in the danger of information security, this plan build up information announcement with isolation data of EMC database server, and design a complete system for information announcement, to carry air quality information synchronicity on both nets of inside and outside in secure way. Besides, on user’s management, via strengthen user’s login security management, increase auditing efficacy, redesign the authority of management system, to resolve the more and more complex demand of authority management. 　　For assessing the applicability of new generation air quality index (AQI) in Taiwan, add the calculation and report function for AQI. That could calculate the AQI by hour, date and area, to compile various statistics, and set up all sorts of AQI related report. 　　In order to provide topical subject of this system, devise a new vision effects style to display environmental protection concept on the air website. To improve the user operation, we redesign menu operation, single window query form , three input selectors and newly trend chart to make user easily to use. 　　Other related monitoring stations data are also integrate to the portal; include the UVI monitor data, international present air quality data, Modis- satellite remote survey, microwave temperature profile system, photochemical assessment monitoring stations, MPLNET systems, Lulin mountain background site and supersite. 　　Regarding to the requirement of data process of weather monitor items, included wind direction, wind speed, the temperature, rainfall, rain strong, UVB, UVA, we redesign the new test and verify program of data processing, data schema store planning, periodical computing assignment, and link with original computing operation, design the data schema, generate all necessary and special computation batch to provide air quality forecast work in regularly. 　　The work to enrich the air quality data could divide into three dimensions: The first, analyzes the archived data of PDP 11 system, which collected air quality data from 19 stations of 16 items , from 1982 to 1993, then transform the data format and insert into EMC system row by row, the imported data could be query and report in EMC system which made the EMC air quality would originate to 1982. The second is to import the calibration data from the first generation air quality database. That include the history calibration data from 1993 September to 2004, users could make a comparison with the air quality history data for reference. The third is to processing the data of mobile stations. The monitor data of mobile stations contain coordinates data attributes. After integrate the mobile station data from middle server, through the GIS service in EPA, system could show the weather station and the air quality station near the mobile station in the map.
