Description
Technical field
The invention belongs to electronic communication fields, and in particular to a kind of smart home monitor control system based on Internet of Things.
Background technique
Smart home is as a newborn industry, the critical point in an introduction period and growth stage, market comsupton idea
It has not yet been formed, but as what smart home marketing was popularized further implements, has cultivated the use habit of consumer, intelligent family
The consumption potentiality for occupying market is necessarily huge, and industrial prospect is bright.Just because of this, domestic outstanding smart home produces enterprise
Industry more and more payes attention to the research to industry market, especially deeply grinding to Business Development Environment and customer demand Long-term change trend
Study carefully.A more apparent defect is the control only realized for household electrical appliance existing for smart home at this stage, and
It is not concerned about household electrical appliance hidden danger that may be present in daily life.In recent years, warming with global climate, people's installation
The quantity of the high-power electric appliances such as air-conditioning is also increasing year by year, and according to statistics, year China's air-conditioning market increases from 1999 to 2002
Rate increases by 0.95% on a year-on-year basis in Jan-Sept, 30% or more, 2015 China's domestic air conditioning yield.According to statistics, whole nation electricity in 2016
Gas class fire, which occurs more than 31.2 ten thousand, to be risen, and wherein reason of fire accounts for 30% for electrical, and place on fire is house, the interior such as dormitory field
Accounting nearly 40%.Therefore, the topic that people discuss warmly is become for the detection of electrical appliance behavior.Such as Electrical Safety is monitored
Control is integrated in existing smart home scheme, improves a grade again for the guarantee of people's daily life.
At present for the monitoring of electricity consumption behavior also in the weak spot of most of smart home products, for electricity consumption behavior
Research mainly has wavelet analysis, and the several methods such as power identification, requirement of the wavelet analysis for hardware is relatively high, and its algorithm
Complexity is also higher.Although power recognition methods is relatively low to hardware requirement, algorithm is also relatively simple, its identify precision compared with
It is low.For the fire caused by electrical appliance fault electric arc, essence is precisely due to produce fault electric arc, and for failure
The monitoring of electric arc detects electric arc using arc spectrum, but it is more demanding to light, is affected by light, secondly, making
With the method for mathematical model, this method is only applicable to theory analysis, and computational complexity is higher, and longer using the time, unfavorable
In reduction accident occurrence probability.Therefore, society and a kind of market intelligence with electricity consumption behavior monitoring good, highly-safe to performance
The requirement of energy family product is also higher and higher.

It is identified the present invention is based on the value that the fast Fourier variation of current parameters on loaded line obtains as electrical appliance
Parameter.Identification function of the invention is in addition to using fast Fourier to change as reference value, the power and type of electrical appliance
Reference data as identification.It is divided into three steps to be identified, the electrical appliance current waveform that the first step goes out difference carries out quick Fu
In leaf operation, obtain matching attribute；Second step finds out the identical electrical appliance related data of matching attribute in matching library；Third step will
The electrical appliance data screened lead to overpowering further screening, and obtain recognition result.
(3) arc-detection technology
Arc-detection mode of the invention is detected using " the flat shoulder belt " in arc characteristic, indoors in route, line
The electric arc that road is caused all has this feature, and detection method is by the collected electricity of a cycle on every route in three-phase electricity
Flow data carries out algorithm analysis, and the current waveform of calculated result in a certain range is fault electric arc waveform, in addition by big
The number that the fault electric arc of amount experimental verification at least generates in one cycle, can be accurate by the detection of the fault electric arc on route
Degree increases substantially.
(4) environmental monitoring technology
The present invention being capable of the environmental datas such as the indoor PM2.5 index of comprehensive monitoring, line temperature and noise.It is passed using line temperature
Acquisition module of the sensor as line temperature detects interior PM2.5 index using the GP2Y1010AU0F of Sharp, and use is highly sensitive
Electret condenser microphone and Simulation scale-up circuit are spent to monitor room noise intensity.
(5) technology of Internet of things
Invention introduces technology of Internet of things for realizing remote monitoring function, including ethernet technology, uses single
Piece Fast Ethernet mac controller W5500.
