Current Sensor Based Home Appliance and State of Appliance Recognition
نویسندگان
چکیده
This paper presents a current sensor-based home appliance and its state recognition method for intelligent outlets. Our system has three main functions: remote control, monitoring, and power supply schedule management. This research focuses particular on the monitoring function. To recognize the appliance and the state of the appliance, we extract ten features based on a measured current signal. In the experiment, we gather a number of signals with various appliances, and find that three features Irms, Iavg, and Ipeak yield valid recognition results of 84.3%, 86.4%, and 90.3% for classifying the state of the appliance into three categories. Moreover, sufficient recognition rates of 97.4%, 97.7%, and 99.0% are obtained by consideration of three candidates.

متن کاملPush-pins: design-by-user approach of home automation programming
A tangible programming interface called ``Push-pin'' is proposed, which involves end-users in designing smart home programs for home appliance automation. Programming on the Push-pin system is based on a stimulus-response model in which an appliance connected to another appliance via a network gets activated when the other appliance is activated. To interconnect two appliances, the user puts a ...
