Description
Technical field
The present invention relates to the fields such as RFID technique, WiFi technology, ambient vibration detection technique, specifically, be a kind of alarm based on WiFi networking design.
Background technology
RF identification, RFID(Radio Frequency Identification) technology, also known as radio frequency identification, is a kind of communication technology, radio signals identification specific objective can be passed through and read and write related data, and set up machinery or optical contact between system and specific objective without identifying.
Radio frequency is usually microwave, 1-100GHz, it is adaptable to short distance identification communicates.
Rfid interrogator also divides movable type and fixed, and the application of current RFID technique is very wide, and such as: library, gate control system, food security is traced to the source.
RF tag is the physical support of product electronic code (EPC), is attached on traceable article, can circulation worldwide be identified it and read and write.RFID(Radio Frequency
Identification) technology is paid close attention to by people in recent years as the key technology building " Internet of Things ".RFID technology early originates from Britain, is applied in World War II distinguish that enemy and we's aircraft identity, the sixties in 20th century start commercialization.RFID technique is a kind of automatic identification technology, and U.S. Department of Defense specifies
After 1 day January in 2005, all military materials will use RFID label tag；FDA Food and Drug Administration (FDA) suggestion pharmaceutical manufacturer utilized RFID to follow the tracks of the medicine often faked from 2006.A series of action such as Walmart, Metro retail business application RFID technique have promoted RFID in global application upsurge especially.When 2000, each RFID
The price of label is 1 dollar.Many researchers think that RFID label tag is much more expensive, and only reducing cost could large-scale application.When 2005, the price of each RFID label tag is about 12 cents, and the price of present ultrahigh frequency RFID is about 10 cents.Can RFID wants large-scale application, is on the one hand intended to reduce RFID label tag price, bring value-added service after on the other hand seeing application RFID.The statistics of statistics office of European Union shows, 2010, European Union had the company of 3% to apply
RFID technique, application distribution identity document and access control, supply chain and inventory tracking, vehicle toll collection, antitheft, produce control, asset management.
RF identification (RFID) is a kind of wireless communication technology, can pass through radio signals identification specific objective and read and write related data, and set up machinery or optical contact between system and specific objective without identifying.
Wireless signal is the electromagnetic field by furnishing radio frequency, and data are sent out on the label being attached to article, with automatic identification and these article of tracking.Some label can be obtained by energy when identifying from the electromagnetic field that identifier sends, and is not required to battery；Also label itself is had to have power supply, it is possible to actively to send radio wave (electromagnetic field of furnishing radio frequency).Label contains the information of Electronic saving, can identify within several meters.Unlike bar code, within RF tag need not be in identifier sight line, it is also possible within embedding tracked object.
Wi-Fi is the technology that the terminals such as PC, handheld device (such as pad, mobile phone) can wirelessly be interconnected by one, and in fact it is a high frequency radio signal.Wireless Fidelity is the brand of a wireless network communication technique, Wi-Fi Alliance held.Purpose is to improve based on IEEE
802.11 the intercommunity between the Wi-Fi product of standard.Someone is known as Wireless Fidelity the LAN using IEEE 802.11 serial protocols.Even Wireless Fidelity is equal to the wireless the Internet networking important component part of WLAN (Wi-Fi be)
Wireless network refers to " Wireless Fidelity " at the category of WLAN, substantially a kind of commercial verification, is also a kind of Wireless networking technologies simultaneously, connected computer by netting twine in the past, and Wireless Fidelity is then to be networked by radio wave；Common is exactly a wireless router, the effective range so covered at the electric wave of this wireless router can use Wireless Fidelity connected mode to network, if wireless router is connected to an adsl line or other online circuit, then be otherwise known as focus.
Wireless network online can simply be interpreted as getting online without being tethered to a cable, and nearly all smart mobile phone, panel computer and notebook computer all support that Wireless Fidelity is surfed the Net, and is to use the widest a kind of wireless network transmission technology now.Being actually and cable network signal is converted into wireless signal, as introducing for everybody in beginning, use wireless router for supporting the related computer of its technology, mobile phone, flat board etc. receives.If mobile phone has Wireless Fidelity function, just can not be surfed the Net by the network of mobile UNICOM having Wi-Fi wireless signal when, eliminate traffic fee.
Wireless network is got online without being tethered to a cable the more commonly used in big city, although the radio communication quality transmitted by adopting wireless fidelity technology is not fine, Information Security can be more weaker than bluetooth, transmission quality also haves much room for improvement, but transmission speed is the fastest, 54Mbps can be reached, meet the demand of individual and social informatization.The topmost advantage of Wireless Fidelity is to need not wiring, can not be limited by wiring condition, be therefore especially suitable for the needs of mobile office user, and owing to launching signal power less than 100mw, less than mobile phone transmission power, so Wireless Fidelity online is also relatively safety and Health.
But Wireless Fidelity signal is also provided by wired network, the ADSL of such as family, partial wideband etc., as long as connecing a wireless router, it is possible to wire signal is converted into Wireless Fidelity signal.Being covered with the Wireless Fidelity signal provided by government or major company in external a lot of developed countries city everywhere for resident, also there is the enforcement of many places in China " " engineering makes this technology be promoted in wireless city.In the experimental city that 4G licence plate is not provided, many local 4G of use turn Wireless Fidelity allows citizen try out.
