Embodiment Construction

[0062] The present invention is described in detail below in conjunction with accompanying drawing:

[0063] The single-point sensing-based household electricity intelligent monitoring method and equipment thereof described in the present invention aim at the defects existing in the prior art, and provide more comprehensive user information and a more reasonable energy-saving method. It is mainly committed to embedded sensing technology, which is used to monitor the electricity usage of the whole family, perceive the signal in the power line through a single sensor, and then identify the unique signal sent by each device through machine learning methods such as pattern recognition. The characteristics of electromagnetic interference EMI noise radiated into the power line when household electrical equipment is working are matched and identified with the added algorithm to achieve the purpose of household appliance monitoring. In this way, more comprehensive user information and...

Abstract

The invention discloses a method and equipment for intelligently monitoring household electricity based on single-point sensing, aiming at overcoming the problems that the existing equipment is inconvenient to maintain and install and can only monitor low frequency signals in the prior art. The method comprises the following steps of: 1, initializing the equipment for intelligently monitoring household electricity based on single-point sensing; 2, detecting turn-on and turn-off actions of household appliances by the equipment for intelligently monitoring household electricity based on single-point sensing; 3, extracting electromagnetic interference characteristics of each household appliance from massively stored data, and judging which household appliances are used by the equipment for intelligently monitoring household electricity based on single-point sensing; 4, writing electromagnetic interference data of the household appliances on power lines into a computer for storage by the equipment for intelligently monitoring household electricity based on single-point sensing; and 5, exiting monitoring of the equipment for intelligently monitoring household electricity based on single-point sensing. The invention further discloses the equipment for intelligently monitoring household electricity based on single-point sensing, which performs the method for intelligently monitoring household electricity based on single-point sensing. The equipment comprises a high-pass filter and the like.

Description

technical field [0001] The invention relates to a method for monitoring household electricity consumption, and also relates to a device, more precisely, the invention relates to a single-point sensing-based intelligent household electricity monitoring method and equipment thereof. Background technique [0002] Today's monitoring of electricity consumption is mainly used to complete two functions: [0003] The first aspect is used to care for the elderly and the disabled. The main requirement is not only to obtain the current resident's activity information (watching TV, cooking, etc.), but also to know the current location information (in the toilet, kitchen, bedroom). For example, if a family with only elderly people does not use electricity for a day, it means that a special situation has occurred and special treatment is required. In this way, dangerous situations can be detected early, treated urgently, and losses can be reduced. [0004] On the other hand, in terms of ...
