Description

A kind of anti-loss device

Technical field

The invention belongs to electronics field, particularly relate to a kind of anti-loss device.

Background technology

Pilferage is the most headachy problem in China's public security field, along with the fast development of China's economy, relate to breaking laws and commit crime of pilferage and be in state multiple, occurred frequently all the time, except theft property, also have some lunatic criminals even to steal infant, bring endless misery to some families.Due to the existence of these situations, a large amount of anti-losing devices has been invented by individuals, the unit of some innovations, comprise property, children, old man.Along with the appearance of the wearable products such as Intelligent bracelet, some neoteric anti-losing devices had also made the wearable product of bracelet form in recent years.Foregoing invention innovation all have employed wireless launcher (what have also has receiving trap), and employ power supply, generally adopt powered battery, and the electricity of battery is limited, can be finished, generally one day, according to power consumption, the available a couple of days had, long also have available some months, but be limited in a word.Some anti-losing device batteries can be changed, and so just need periodic maintenance, just may cause losing efficacy if do not changed in time; What have is then non-exchange, and running down of battery just can only be scrapped.Owing to adding power module, too increase the unreliability of whole device simultaneously, except the problem that foregoing electricity causes, also have the problems, heat dissipation problem etc. such as the integrity problem of power module itself, power supply interface contact quality, these all likely cause anti-losing device to lose efficacy.Once anti-losing device lost efficacy, just do not play due effect, and unpredictable loss may be caused, even lead to human world tragedy, as in the situation that goes adrift neonate.

Radio-frequency (RF) identification is (English: Radio Frequency IDentification, abbreviation: RFID) be a kind of wireless communication technology, related data can be read and write by radio signals identification specific objective, and without the need to setting up machinery or optical contact between recognition system and specific objective.The basic technique principle of RFID originates from World War II, and initial allied forces utilize radio data technology to identify aircraft between ourselves and the enemy and warship.After the war, due to higher cost, this technology is mainly used in military field always, is widely applied at civil area very not soon.Until the 80s and 90s in last century, along with the raising of chip and electronic technology and universal, Europe starts to take the lead in RFID technique to be applied to the civil areas such as highway toll.To earlier 2000s, RFID has welcome a brand-new developing period, it starts in the value of civil area the extensive concern obtaining countries in the world, particularly at western developed country, RFID technique is widely used in the civil areas such as the production automation, gate inhibition, highway toll, parking lot management, identification, cargo tracking, its new range of application, also in continuous expansion, emerges in an endless stream.RFID label tag is divided into passive, semi-passive (also referred to as half initiatively), initiatively three classes.Passive label, also referred to as passive RFID tags, does not have internal power supply.Its internal integrated circuit is driven by the electromagnetic wave received, and these electromagnetic waves are sent by RFID reader.When label receives the signal of sufficient intensity, data can be sent to reader.These data not only comprise No. ID (whole world uniquely indicates ID), can also comprise the data preexisted in label in EEPROM.Because passive label has cheap, compact, without the need to the advantage of power supply, the RFID label tag of existing market mainly passive type.

The frequency of operation of RFID label tag is a key feature of RFID technique, not only decide radio-frequency recognition system principle of work (inductive coupling or electromagnetic coupled), decipherment distance, also decide the complexity of radio-frequency (RF) tag and read write line realization and the cost of equipment.The radio-frequency (RF) tag be operated on different frequency range or frequency has different features.The frequency range that applying in radio frequency identification occupies or frequency have generally acknowledged division in the world, are namely positioned among ism wave band.Typical frequency of operation has: 125khz, 133khz, 13.56mhz, 27.12mhz, 433mhz, 902 ~ 928mhz, 2.45ghz, 5.8ghz etc.

(1) low-frequency range radio-frequency (RF) tag.Low-frequency range RFID label tag is referred to as low frequency RFID tag, and its operating frequency range is 30khz ~ 300khz.Typical operating frequency has: 125khz, 133khz.Low frequency RFID tag is generally passive RFID tags, and its work capacity is obtained from the radiating near field of reader pickup coil by inductive coupling mode.When transmitting data between low frequency RFID tag and reader, low frequency RFID tag need be positioned at the near field region of reader antenna radiation.The reading distance of low frequency tags is generally less than 1 meter.The typical apply of low frequency tags has: animal identification, container identification, tool identification, electric locking antitheft (automobile key with built-in transponder) etc.Low frequency tags has various appearances form, and what be wherein applied to animal identification has: Necklet-type, ear board formula, injecting type, pill type etc.The main advantage of low frequency tags is embodied in: RFID label chip generally adopts common cmos technique, has power saving, cheap feature; Frequency of operation does not retrain by radio frequency control; Can through-fall, organic organization, timber etc.; Be applicable to very much in-plant, low velocity, data volume and require less application.The inferior position of low frequency tags is mainly reflected in: RFID label tag stored data amount is less; Low speed can only be applicable to, closely identify application; Compared with high-frequency label: the RFID label antenna number of turn is more, and cost is higher.

(2) medium-high frequency section radio-frequency (RF) tag.The frequency of operation of medium-high frequency section RFID label tag is generally 3mhz ~ 30mhz.Typical operating frequency is: 13.56mhz.The radio-frequency (RF) tag of this frequency range, from applying in radio frequency identification angle, because its principle of work is identical with low frequency RFID tag, namely adopts inductive coupling mode to work, so should be classified as in low frequency tags class.On the other hand, according to the general division of radio frequency, its working frequency range is also called high frequency, so be also often referred to as high-frequency label.Radio-frequency (RF) tag in view of this frequency range may be a kind of radio-frequency (RF) tag of maximum in practical application, as long as thus high and low understanding is become a relative concept by us, namely can not cause the confusion in understanding at this.For the ease of describing, we are referred to as intermediate frequency radio-frequency (RF) tag.Intermediate frequency label generally also adopts passive design, and its work capacity is the same with low frequency tags, is also to be obtained from the radiating near field of reader pickup coil by inductance (magnetic) coupling scheme.When RFID label tag and reader carry out exchanges data, RFID label tag must be positioned at the near field region of reader antenna radiation.The reading distance of intermediate frequency label is generally also less than 1 meter.The basic characteristics of medium frequency standard are similar to low-frequency standard, due to the raising of its frequency of operation, can select higher message transmission rate.RFID label antenna design is relatively simple, and RFID label tag is made generally in standard card shape, and typical apply comprises: electronic ticket, electronic ID card, electric locking antitheft (electronic telecontrol door lock controller), taking care of books and tracking etc.

(3) ultrahigh frequency and Microwave RFID labels.The radio-frequency (RF) tag of ultrahigh frequency and microwave frequency band, its typical operating frequency is: 433.92mhz, 862 (902) ~ 928mhz, 2.45ghz, 5.8ghz.Microwave RFID labels can be divided into active RFID tag and passive RFID tags two class.During work, RFID label tag is positioned at the far zone field of reader antenna radiation field, and the coupling scheme between label and reader are electromagnetic coupled mode.Reader antenna radiation field provides radio-frequency (RF) energy for passive label, is waken up by active label.Corresponding radio-frequency recognition system reading distance is generally greater than 1m, and typical case is 4 ~ 6m, maximumly reaches more than 10m.Reader antenna is generally directional antenna, and the radio-frequency (RF) tag only within the scope of reader antenna directional beam can by read/write.Due to the increase of reading distance, in reading area, in application, likely occur the situation of multiple radio-frequency (RF) tag simultaneously, thus propose the demand that many labels read simultaneously, and then this development of demand becomes a kind of trend.At present, advanced radio-frequency recognition system is all using the key character of many RFID label tag recognition problems as system.With state-of-the art, this frequency range compares successful product and is relatively concentrated on 902 ~ 928mhz working frequency range.2.45ghz and 5.8ghz radio-frequency recognition system emerges mainly with half passive RFID tags product.Half passive RFID tags generally adopts button cell to power, and has reading distance far away.Typical recognition distance is 3 ~ 5m, has individually the product reaching 10m or more than 10m.For the radio-frequency (RF) tag that can wirelessly write, under normal circumstances, write distance is less than recognition distance, and its reason is to write and requires larger energy.Data-storing capacity is generally limited within 2kbits, and typical data capacity pointer has: 1kbits, 128bits, 64bits etc.Typical apply comprises: moving vehicle identification, electronic ID card, warehouse logistics application, electric locking antitheft (electronic telecontrol door lock controller) etc.

Summary of the invention

The object of the invention is to solve the problem that may lose efficacy that existing anti-losing device causes owing to there being power supply, the major measure of dealing with problems have employed passive RFID tags.Some adopts the application of passive RFID tags at present, the books in such as some libraries, in the cargo container management of some Transportation Enterprises, although not based on anti-lost in these management systems, but what have also has anti-lost function, but these are all the anti-lost of article in an absolute space determined, be exactly especially typically the books in library, the passive RFID tags on pipe books is read out by the passive RFID tags reader that border is installed, if unauthorized taking out of will be reported to the police, what protect here is exactly these books article determining in the invariant space of library, the systems such as ETC also can in the absolute space determined (although space is completely not closed, monitoring point is spatial dimension of its monitoring fixing is also fixing) monitoring passive RFID tags, although be not used to anti-lost here, principle is the same substantially.And the present invention is directed to anti-lost to as if be determine the anti-lost scope of space people, determine the people of the anti-lost scope of absolute space and determine the thing of the anti-lost scope of space.Determine the people of the anti-lost scope of space, the young children that the such as head of a family carries, it is generally acknowledged that this anti-lost scope near the head of a family is safe, because the head of a family is mobile, so this space is not a fixing absolute space, but determination space relative to the head of a family, determine the people of the anti-lost scope of absolute space, the neonate of such as obstetrics and gynecology hospital, the concentrated nursery at their place is exactly a fixing absolute space, it is an anti-lost scope needing to ensure, or ward neutralizes the young children that the father and mother that look after stay together, this ward is also a fixing absolute space, determine the thing of the anti-lost scope of space, such as people are carry-on, with the wallet that car carries, the properties such as mobile phone, with it it is generally acknowledged, this scope on car is safe, it is an anti-lost scope needing to ensure, it is then unsafe for having departed from, due to people, car is mobile, so this space is not a fixing absolute space, but the determination space that relative, although the car of cargo transport likely its goods transported also uses passive RFID tags, but be all again with the equipment based on passive RFID tags on the ground such as warehouse a fixed position that stops, instead of adopt in movement, so not at the thing determining space scope.In the application that these are anti-lost, also nobody adopts the anti-losing device based on passive RFID tags at present, so this programme is different from prior art.Someone can say, adopting the library management related system of passive RFID tags (systems designed by the passive 13.56 MHz RFID label tag schemes that can reach 40 years serviceable life that such as this Planck European Law history institute libraries of German mark adopts), this system is very huge and based on taking care of books, simplify this type systematic only retain anti-lost relevant function and transform neonate that (note must transform) then use hospital with it anti-lost not just? technical thought of the present invention in fact just have employed such thinking, certainly this thinking more than also has other thinking, but belong to prior art with regard to this thinking? of course not, the invention much with anti-lost function has been had (to comprise utility model at present as previously stated, have for child old man anti-lost, have for properties such as wallet mobile phones anti-lost), but because technology prejudice limit, employing passive RFID tags is not expected in these inventions per capita, in addition, in the application of aforementioned library to as if a kind of object and object person of the present invention be diverse, in the application of aforementioned library to as if a kind of absolute space determined in object and object (as the wallet carried with) in the space determined of the present invention be also two kinds of distinct application scenarios, the present invention enormously simplify the anti-losing device of all inventions in the past for identifying the partial devices of anti-lost object and substantially increasing reliability by adopting passive RFID tags, extend the life-span, thus anti-lost effect can be guaranteed, yes one there is outstanding substantive distinguishing features and possess the innovation of remarkable benefit.Also some system have employed active RFID tag, such as in some supervision places, just have employed the bracelet of active RFID tag to monitor its position, prevent them from running away from an absolute space determined (supervision place) for criminal or suspect.Active RFID tag and passive RFID tags only differ from a word, in fact should use or have much different, the maximum feature of active RFID tag to have power supply, the benefit brought thus is that power is large thus can read the distant of monitoring, general more than 10 meters, what have even can reach more than 50 meters.The shortcoming of charged describes above, no longer repeats here.The distant of monitoring can be read, sometimes be an advantage, and in anti-lost application scenario of the present invention, be a fatal shortcoming, and because anti-lost application scenario of the present invention is a less scope, the scope that near person things such as (or) cars or gateway etc. are less.Such as anti-lost for what carry one's purse along, leave tens meters, pocket far also can monitor active RFID tag and cause thinking that wallet is not also reported to the police with it, that substantially just loses anti-lost effect when stolen, when finding Deng you, thief has early run away, therefore the present invention reasonably can not be enlightened from the application of active RFID tag, is one equally and has outstanding substantive distinguishing features and possess the innovation of remarkable benefit.Anti-loss device technical scheme of the present invention is as follows:

Comprise identity device and monitoring device, wherein said identity device comprises passive RFID tags, and carrys out the anti-lost object of unique identification by a passive RFID tags; Described monitoring device comprises having and carries out the module for reading and writing of read-write capability, the prompting module that can be connected with mobile phone or warning horn and power module to corresponding passive RFID tags, and is powered by power module wherein;

adapt to very much for only having the situation of or minority exit and entrance, a such as room, can the monitoring device of all standing as long as to arrange one on doorway for gynemetrics's infant care room, as long as the baby being provided with passive RFID tags just can monitor once this door, trigger prompting module when its passive RFID tags read through model monitors passive RFID tags and make response, such as general watch capable of reminding is shown with baby and has passed in and out, also can be that ear-piercing alarm represents that baby may be stolen, specifically can depend on the circumstances, the second situation is arranged in the anti-lost scope of anti-lost object, such as on belt, hang a monitoring device, monitor the wallet in bag or pocket, mobile phone, trigger prompting module when its passive RFID tags read through model does not monitor passive RFID tags and make response, do not monitor expression wallet, mobile phone may be stolen, this mode also may be used for monitoring the baby slept in ward, at the head of a bed, a monitoring device is set, when the passive RFID tags that the identity device that monitoring location baby is arranged with it comprises, just mean that baby is likely stolen, also be likely oneself climbed away, then trigger alarm set remind or report to the police.Above-mentioned two kinds of facilities can adopt simultaneously, such as gynemetrics neonate family ward, baby does not generally concentrate and is put into nursery, but mother and other households are with together, evening is in order to antitheft, can simultaneously in bed side and doorway respectively arrange one, carry out reminding alarm according to pattern above, at this moment a just formation dual fail-safe.The mode of prompting module reminding alarm can sound (voice message, music tone ringer, general alarm song, ear-piercing alarm song), light (bright or flicker), dynamic (vibrations, start auction, beat, blowing), change temperature (heating, turn cold), scent of and (send fragrance, stink or other characteristic taste) in carrying out remind that (alarm is also a kind of prompting, the prompting that just a kind of pungency is stronger), only can adopt wherein a kind of mode, also various ways can be adopted to remind simultaneously, the another kind of form of reminding is that other device of interlock is with sound, light, dynamic, change temperature, to scent of etc. above-mentioned in a kind of mode or various ways remind simultaneously, if do not received by suitable people because remind, that is reminded and does not also use, by interlock (being generally the communication mode by networking or operator), prompting is dealt into the device that suitable people can receive prompting, such as mobile phone, on warning horn, at this moment remind just effective.
