Description
Technical Field
The utility model relates to a non-intrusive formula load monitoring system, visible light communication equipment and load monitoring equipment based on power line carrier and infrared remote control belongs to intelligent house management system technical field.
Background
The Non-Intrusive Load Monitoring technology (NILM technology) is a technology for analyzing and identifying energy consumption information of electrical appliances, and the principle of the technology is to identify the time-space distribution condition of energy consumption of downstream electrical appliances based on the fluctuation rule of power line energy consumption data of the electrical appliances.
There are two main categories of prior art non-intrusive load identification systems. One is to remotely control the household appliances in the form of the internet of things. The technology carries out artificial information calibration on the type and distribution of the household appliances in fact on the basis of solving the problem of networking the control information of the household appliances. However, there is a great problem in such control that whether or not a response of the corresponding home appliance is obtained after the control signal is transmitted is unknown. This is more like a broadcast system, where the information is delivered unidirectionally without obtaining a two-way feedback confirmation.
Another type of prior art technique focuses on identifying the type of electrical start-stop appliance and the amount of power consumption by using the characteristics of the fluctuations in voltage and current on the identification bus (collectively known as NILM techniques). The technology collects current and voltage signals on a line by various means, processes and analyzes the signals, and identifies the characteristics of the electric appliance based on various machine learning algorithms for supervision and learning. However, the deployment of such algorithms requires active input of a user, or feature library calibration by a developer, and automatic batch annotation cannot be achieved, so that the application of the algorithms is greatly limited. Meanwhile, the application can only realize identification and cannot realize management and control. Therefore, in the application, the method belongs to a link of passively receiving information.
Therefore, in the prior art, signal fluctuation generated by the state change of the electrical appliance can be only passively identified, and the accuracy cannot be ensured. More importantly, the monitoring device based on the machine learning algorithm can only diagnose the power consumption behavior generally, but cannot control the electrical appliance according to the identification result, so that the NILM technology cannot form closed-loop control with the electrical appliance, and cannot give play to the NILM technology and the maximum value of the electrical appliance.
