III. ADAPTIVE ENVIRONMENT In this section we describe how SHEAP adapts to the en-vironment, using environmental information. Such information is given directly by sensors (e.g., photo-resistors, motion, tem-perature, etc.) and indirectly from the users activity patterns. Using this information, SHEAP can establish context aware-ness (Section III-A) to optimize appliance utilization. SHEAP can also advise users on energy efficient alternatives to currently used appliances. We now elaborate on these two components.
Lion, depending on the habits of each user. The smart home can detect the usage of non-energy efficient technologies. This de-tection can be done by combining the readings from sensors in the smart home, and the power consumption of loads. For ex-ample, the home is aware that an efficient fluorescent light bulb might be consuming 15 W to produce the same lumen that an in-candescent bulb of 60 W would produce, but it realizes that the bulb which is at home consumes 60 W, hence, the system can infer that a better bulb can be used. An alarm can then be trig-gered to notify users of the possible enhancement. Information about such upgrade may come from server technologies such as server subscription, information loaded manually by the user or the smart grid using the status information protocol. However, a straightforward approach might not work, since the new light bulb might not be feasible for the usage that the users are giving to the bulb, rather SHEAF considers cost vs. benefit ratio (CBR), as follows:
3 . ปรับสภาพแวดล้อม ในส่วนนี้เราจะอธิบายวิธีการ sheap ไปใน vironment โดยใช้ข้อมูลด้านสิ่งแวดล้อม ข้อมูลดังกล่าวจะได้รับโดยตรง โดยเซ็นเซอร์ ( เช่นรูปตัวต้านทาน , เคลื่อนไหว , TEM perature ฯลฯ ) และโดยอ้อมจากกิจกรรมของผู้ใช้รูปแบบ การใช้ข้อมูลนี้ sheap สามารถสร้างบริบททราบเนส ( มาตรา iii-a ) เพื่อเพิ่มประสิทธิภาพการใช้เครื่องใช้ไฟฟ้า SHEAP can also advise users on energy efficient alternatives to currently used appliances.
