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 with ambient temperature detection function based on wifi networking design.
Background technology
RF identification, RFID(RadioFrequencyIdentification) 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, without setting up machinery or optical contact between the system of identification and specific objective.
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, as: library, gate control system, food safety is traced to the source.
Radio-frequency (RF) tag is the physical support of product electronic code (EPC), is attached on traceable article, can circulation worldwide it is identified and reads and writes.RFID(RadioFrequencyIdentification) technology receives the concern of people in recent years as the key technology building " Internet of Things ".RFID technique early originates from Britain, is applied in World War II and distinguishes enemy and we's aircraft identity, and the sixties in 20th century starts commercialization.RFID technique is a kind of automatic identification technology, and after U.S. Department of Defense specifies on January in 2005 1, all military materials will use RFID tag；FDA Food and Drug Administration (FDA) advises that 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 applying RFID technology have promoted RFID in global application upsurge especially.When 2000, the price of each RFID tag is 1 dollar.Many researcheres think that RFID tag is much more expensive, and only reducing cost could large-scale application.When 2005, the price of each RFID tag is about 12 cents, and the price of present ultrahigh frequency RFID is about 10 cents.Can RFID wants large-scale application, is to reduce RFID tag price on the one hand, bring value-added service after seeing applying RFID on the other hand.The statistical data of statistics office of European Union shows, 2010, there was company's applying RFID technology of 3% in European Union, 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, it is possible to by radio signals identification specific objective and read and write related data, without setting up machinery or optical contact between the system of identification and specific objective.
Wireless signal is the electromagnetic field by furnishing radio frequency, and data are sent out from being attached on the label article, with automatic identification with follow the trail of these article.Some label can be obtained by energy when identifying from the electromagnetic field that evaluator 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.With bar code the difference is that, radio-frequency (RF) tag need not be within evaluator sight line, it is also possible to embeds within 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, held by Wi-Fi Alliance.Purpose is to improve based on the intercommunity between the Wi-Fi product of IEEE802.11 standard.Someone is known as Wireless Fidelity the LAN using IEEE802.11 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 networked by radio wave；Common is exactly a wireless router, the effective range so covered at the electric wave of this wireless router can adopt 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 use the widest a kind of wireless network transmission technology now.Be actually and cable network signal converted to wireless signal, as beginning for everybody introduce the same, use wireless router for the related computer supporting 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 when there being Wi-Fi wireless signal, 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 as, Information Security can be more weaker than bluetooth, transmission quality also haves much room for improvement, but transmission speed is very fast, 54Mbps can be reached, meet the demand of individual and social informatization.The topmost advantage of Wireless Fidelity is in that to connect up, the restriction of wiring condition can not be subject to, be therefore especially suitable for the needs of mobile office user, and owing to launching signal power lower than 100mw, lower than mobile phone transmission power, so Wireless Fidelity online is also relatively most 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 to 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 much local enforcement 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.
