建構居家環境之無線網路監控系統

Abstract

本研究旨在建構結合居家環境感測、家電設備近端與遠端控制、安全監測、緊急警報並可透過網際網路進行管理維護的智慧型居家監控系統。其次，建構模型屋，整合上述系統提供示範功能。 本示範系統使用了內建網路晶片的可程式化介面控制卡 (PICNIC)、多種感測器、IP攝影機與無線基地台，並使用VB撰寫使用者介面軟體，將所有功能作具體呈現。監控的環境因子包括：二氧化碳、一氧化碳、瓦斯、溫度、濕度、照度、介質溫度與含水率；控制的家電包括：照明燈光、殺菌燈光、冷/暖氣、通風換氣門、加濕機、除濕機與盆栽灌溉設備等；示範的整合性系統包括門戶安全、室內外影像監控、緊急簡訊通報、滴灌自動化、溫度與濕度控制、管道間殺菌、通風換氣，以近端與透過網路的遠端控制等。 本研究成功地在示範屋所模擬的居家環境中融入總計八種感測器與八種家電設備，除了提供傳統的近端控制功能之外，亦允許透過網際網路在遠端進行即時監控與異常狀況的掌握，更與居家的防災、防盜、緊急警報與文字或語言簡訊傳輸等安全管理系統結合，並建立使用者介面軟體。整套系統雖然建立於模型示範屋內，但所示範的系統都可應用於實際的環境。

The first objective of this study is to develop a web based intelligent system, consists of home environment monitoring, home appliance on-site/web based remote control, home security, and emergency alarm system. The second objective is to build a scale-down house demonstrating above mentioned functions. This demo system utilize PIC network interface card (PICNIC), sensors, IP camera and wireless access points, and use VB as platform to develop user interface software. Environmental factors monitored including: CO2, CO, natural gas, air temperature, air relative humidity, light intensity, temperature and moisture ratio of potted-plant growth media. Home appliances controlled including: lamps for illumination, lamps for disinfection, air conditioning, heating, air exchange inlet, humidifier, dehumidifier and watering pump. Integrated systems demoed including: door/window break-in alarm for home security, indoor/outdoor video monitoring, emergence SMS alarm, drip irrigation control, indoor temperature and humidity control, disinfection in air-duct, air exchange, local and web-based remote control of home appliances, etc.. Totally 8 types of sensors and 8 types of home appliance provided with on-site control and web-based remote control capabilities were successfully integrated in the scale-down demo house. A software served as the user interface was developed to combine above mentioned system with the security and emergence alarm system, which can send simple message, text or voice, to system manager. Although all system was integrated in the scale-down demo house, they can be used in real world applications.
