基于最小二乘法的用电器在线识别系统
Electrical appliances online identification system based on least squares method
摘要
Abstract
Improper operations such as aging of electrical appliances,long working hours,and forgetting to turn off can easily cause short circuits and leakage,and even lead to fires resulting in serious economic losses.Therefore,an electrical appliances online identification system based on the least squares method is proposed.The system can acquire full-cycle current waveform signals from the main line by means of high-speed ADC and then perform calculations using the least squares method to identify the online status of electrical appliances.The system also can collect line voltage,frequency,temperature and other data,send it to the serial screen for display,and upload the data to the cloud server by means of the WiFi module.Users can view and manage electrical appliances remotely in the mobile APP.The experimental results show that the designed system runs stably and reliably,and has high recognition accuracy and strong practicability,which can meet the daily life monitoring needs of electrical appliances关键词
