Method for Realizing Smart Home Based on RFID Tag and Hash Function Identification Mapping

Abstract

The invention discloses a method for realizing an intelligent home based on RFID (radio frequency identification devices) labels and identity mapping of hash functions. The method specifically comprises the following steps: deploying an active RFID label for each home sensor, and putting active RFID label readers in corresponding intelligent home gateways; collecting real-time state index data by the sensors; encapsulating the collected real-time state index data and sensor parameters into the corresponding active RFID labels in the form of an electronic data table of a transmitter with the standard of IEEE1451.7; accessing the RFID labels by the active RFID label readers, performing normalized mapping transformation on the accessed RFID labels and the numbers of the intelligent home gateways through different hash functions, and generating identity symbols with unified lengths and formats; analyzing the numbers of the intelligent home gateways, the real-time state index data of various home detecting targets and the sensor parameters by an intelligent home monitoring and managing platform according to the corresponding hash functions. According to the invention, the wiring limitation of a wired network is solved, standard signal collecting interfaces and unified data formats of the sensors are realized, the safety is high, and the management is efficient and unified.

Description

technical field [0001] The invention relates to smart home, in particular to a method for realizing smart home based on RFID tags and hash function identification mapping. Background technique [0002] Smart home is the organic combination of various subsystems related to home life (such as home appliance control, security alarm, remote control, environmental monitoring, community service, network communication, etc.), creating a safe, comfortable, convenient, Efficient living environment. The whole system generally integrates security control system, home automatic control system, multimedia entertainment system, and remote control system. The intelligent terminal adopts a touch-type large-screen LCD display, and the intuitive graphical operation interface brings convenience and fashion to the user. experience. [0003] At present, there are many technical systems in smart home, whether it is signal collection or communication transmission, which affects the unification o...

Problems solved by technology

[0005] Many of the current smart home network systems are based on wired signal acquisition and communication methods, which have obstacles such as limited wiring space for home sensors, difficulties in wiring construction, and inconvenient line adjustments;

[0006] 2. The sensor signal acquisition interface standard is not uniform;

[0011] In the application of smart home, there are various background management modes based on home gateway, Internet remote monitoring, and operator MTC. The information models and management mechanisms used are different, and the technical systems are diverse, which is not conducive to industrial promotion;

[0012] 5. Leakage of family information;

[0013] Smart home needs to monitor the state of the family. The monitoring data can be intercepted through the network and background technology, and the specific situation and privacy of the home environment in a certain family can be found, which has certain security risks.

[0014] Therefore, there is an urgent need to provide a solution to solve the limitations of wired network wiring and the non-uniform standards of sensor signal acquisition interfaces, etc., to obtain household information data with uniform formats and high security, so that these household information data can be obtained efficiently and efficiently. unified management
