摘要:	本研究已成功整合網際網路傳輸技術、感測器技術及電子控制技術，開發出一套可應用於室內環境監測系統（Indoor Environment Monitor System，簡稱IEMS），本系統具溫濕度及二氧化碳感測器，能將室內溫度、濕度及二氧化碳，透過網路傳遞至後端伺服器；在電力監測方面，裝置電力監視器記錄用電量（kWh）、時間與日期，瞭解建築物每天每一時刻用電量的變化。依據實驗室基本性能測試，IEMS之資料傳遞、自動除錯/自我救援及修復機制等功能皆能正確執行。在模擬測試期間IEMS穩定操作時間佔總測試時間之95%以上，平均封包遺失率為0.17%；在現場測定期間平均封包遺失率為0.08%，IEMS穩定操作時間佔總測試時間之98%以上。由現場監測結果可知，調查樓層於上班時間平均溫度為27?28℃；平均濕度為49.5?68.4％間；二氧化碳濃度為400?800ppm間；平均用電量為17kWh，扣除掉開會期間之上班時間，冷氣用電量約為照明與其他耗能設備用電量的2倍，且會因室內人員活動行為及當日氣候狀況而稍有增減。相互比較分析，可發現在室外溫度上升時，用電量增加，這時主要用電以冷氣用電量為最高，進而使室內溫度、室內濕度呈現下降趨勢；室內二氧化碳濃度增加，用電量也隨之增加，這時與室內人員有關，室內人數增多，各項耗能使用電器頻率增加，因而導致用電量增加。 The purpose of this research is to develop an indoor environment monitor system (called IEMS) to monitor indoor environment. The IEMS can monitor indoor environment such as temperature, humidity and carbon dioxide and then continuously transmitted to the server for storage and calculations. We can use an electricity meter which provides information such as time, date, total electricity (kWh), etc. on electricity use by a building. We can use this information to understand the change of the energy consumption at every moments and every day in a building. The laboratory test showed that the IEMS can be the correct to carry out all oneself. The IEMS stability operating time had reached 95% of the entire period and the average losing rate of package is 0.17% during mock test. In field situation, the IEMS stability operating time had reached 98% of the entire period and the losing rate of the package is 0.08%. Field situation test show that the average temperature is 27~28℃, the average humidity is 49.5~68.4％, the thickness of carbon dioxide is among 400- 800ppm and the average energy consumption is 17kWh during working time. The air conditioning consumed two times as much energy as light and other equipment and will slightly increase and decrease because of indoor people activity behavior and climate on the same day. Relatively analysis each other can find that when temperature rises outside the room, the energy consumption increases. The air conditioning use the highest electricity at this moment and make indoor temperature and humidity lower the trend. The thickness of indoor carbon dioxide increases, the energy consumption increases too. The phenomenon relate to indoor people at this moment. The indoor number of people increases caused equipment use frequency, therefore cause the energy consumption to increase.
