Below in conjunction with attached drawing, the invention will be described in further detail:
Smart home system provided by the invention includes following several parts: 1. market multimedia delivery system, 2. intelligent room
Interior network, 3. internet, 4. big data information server, 5. cell broadcasting system further include data transmit-receive module, data transmit-receive
The wireless terminal display module of wireless communication module, the wireless router are connect by wired with internet.It is wherein described
Market multimedia delivery system includes: the Database Systems of all periphery sales fields.
All periphery sales fields information and market multimedia delivery system 2 constitute mall information system 1.
1. market multi-medium information spreading system, as shown in Fig. 1 smart home flow chart, complete market multimedia publication system
System is connected to each other with Intelligent indoor network system shown in Fig. 2.The market multimedia delivery system is as shown in Fig. 2, commodity acquisition, number
Based on library system, commodity ex-warehouse, real-time update market merchandising database information.Commodity data retrieval is matched in real time with database
Set retrieval, guarantees the accuracy of market merchandise news, then is used to take with internet big data information by internet platform
Business device carries out real time communication, and video, audio signal, pictorial information and roll titles are passed through interconnection with the coding mode of high quality
Network passes to big data information server, and then internet is that platform is logical by router and Intelligent indoor network shown in Fig. 2
Letter is handled by the reception that Fig. 2 Intelligent indoor network 5 carries out data, and then carries out corresponding merchandise news reality in display terminal
When display function.Other than the preferential real time information of commodity, can with real-time release Weather information, the instant messages such as emergency notice,
Guarantee the diversity and real-time of information update.
Wherein, the cell broadcasting system includes that Cell Broadcast CB 1 arrives Cell Broadcast CB N etc., and it is small to collect transmission by internet
All kinds of life informations in area are to big data information server.
Router is communicatively coupled with the internet, obtains the real-time letter of internet big data information server
Breath；
Router is connected to the network in fat server, with the network, for carrying out with the wireless router
Information exchange after carrying out sorting algorithm processing to the database information of received periphery sales field, and then is led to target device
Letter, and real-time messages transmitted by internet end are received by the router, and then with the touching to the intelligent household terminal
It touches display screen and sends corresponding real time information.Several intelligent household terminal touch display screens are connected with the fat server；
The fat server connects the router, and integrated article item algorithm analytic function.The commodity point
Class algorithm is specially to introduce are as follows: the merchandise news currently obtained from market database by big data information server 3 classifies and is
One mapping process, the commodity for not indicating classification are mapped in original classification, are mapped as one-to-one or one-to-many reflect
It penetrates.The first step carries out product features merchandise news structuring, i.e., as unit of in the household multifunctional server by word and mentions
It takes, occurs situation quantization weighting in a document to the Feature Words selected, quantifying weighted model certainly can be used Boolean Model, can also
Using other such as word frequency models or TF-IDF model.Then merchandise news is carried out by stages, just as the dimension of vector
To indicate merchandise news.
Word frequency, which calculates, relies on TF-IDF formula:
In the formula, W (t, d) is weight of the word t in merchandise news d, and tf (t, d) is word of the word t in merchandise news d
Frequently, N is to obtain commodity sum, and n is to obtain commodity to concentrate the commodity number for t occur.It carries out after as above handling, passes through big data information
The merchandise news that server 3 obtains becomes a set of words, then merchandise news can regard a term vector, entire commodity collection as
A matrix is constituted with set of words.The matrix is the core data of commodity classification, the structural classification on word frequency statistics matrix
Then device assigns weight to the term vector of commodity using the disaggregated model established, then by algorithm according to having divided device and commodity vector
Calculate the classification of commodity.After carrying out above-mentioned algorithm in the fat server 7, classification information by it is described routing with
Radio receiving transmitting module is connected, and is shown to audient finally by display terminal is touched.
Multiple intelligent household terminal touch display screens are connected with fat server, carry out related communication connection；
Wherein, the big data information server is for collecting market multimedia delivery system and Cell Broadcast CB described in transfer
The real time data information that system is issued, and carried out in data by the wireless router of the internet and Intelligent indoor network
Turn and transmits.
Wherein, the radio receiving transmitting module includes single-chip microcontroller and wireless communication transceiver module composition, or by individually wireless
Communication module is constituted.The wireless communication module and fat server carry out information exchange, and pass through single-chip microcontroller and touch screen
The display that driving circuit drives touch display screen module to carry out real time information updates.
A kind of smart home system is provided with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the flow chart including smart home system,
