Technical field

[0002] the present invention relates to wireless communication field.Especially, the invention provides portable wireless proximity (proximity) monitoring, the sign checking that maybe can wear in the device, and contiguous sensation (sensation) monitoring.

Background technology

[0003] rfid system is used in several industry, be used for such as stock's control, assets checking, and vehicle motion is followed the tracks of such application.Rfid system is made up of two members usually, and they are reader (readers) and label.Reader normally is mounted on the wall or is installed in the device on the sales counter, and it is broadcast to label and its soluble information from label with interrogating signal, as certain purposes.Label device normally little, plastic package, it is placed on the article that carried by individuality or in these article, and is used for several commercial Application, follows the tracks of such as stock's control, assets checking and vehicle motion.Label comprises relevant type of items or usually for the information of the significant unique identification number of this system.Obtain information by utilizing from this label such as magnetic, magnetic force, radio frequency (RF), microwave and of this sort electromagnetic wave inquiry label.

[0004] most rfid systems use near 1MHz or inquiry on 1MHz and response frequency, its frequency of normal use be 126KHz, 915KHz, 13.56MHz, and 2.45GHz.At these frequency places, the influence that label is shielded easily, this shielding especially by such as can interrupt their functions (disruptive to their functioning) such as the such shielding that human body brought of hand.

[0005] lower label frequency can appropriateness be resisted the shielding that is brought by human body and other object, but because bandwidth and distance limit, it only possesses limited radio-frequency enabled.In addition, this lower frequency tag is quite huge.Bandwidth trend towards increasing and when operating frequency increases label trend towards diminishing.In addition, interrogating range is maximum at about 915MHz place, and begins to descend once more after 915MHz.Unfortunately, higher frequency is easier is shielded for these, especially brings shielding by human body.

[0006] two kinds of basic labels classification is arranged: passive with active.Passive label is by absorbing the interrogating signal energy, and uses this energy to wake the semiconductor identification chip in the label up and work and interrogating signal is made response.This energy also is used to send it back 1/1000 so little electromagnetic signal of initial signal intensity normally.Active label has the battery as a label part, and it allows the return signal energy to be exaggerated, thereby sends long distance.

[0007] the RFID label is inquired by the reader that sends and receive the electronic information (electronics) that works in 0.1 to 0.5 milliwatt zone usually.Tag interrogation appears at scope usually from 1 inch to 12 feet distance, as passive label.Active label has much bigger transmission range, and transmission that can be frequent is from 3 feet to 1000 feet or more, and size is also much bigger usually.

[0008] radio frequency identification technology has been developed by many companies, this comprises that Motorola Inc./Indala (sees United States Patent (USP) the 5th, 3780,880 and 5,565, No. 846), Texas Instrument (sees United States Patent (USP) the 5th, 347,280 and 5,541, No. 604), micron/Philips Semiconductors, Single Chip Microcomputer (SCM) system (Single Chips Systems) (see United States Patent (USP) the 4th, 442,507; 4,769.074; 5,095,362; 5,296,722; And 5,407851), CSIR (sees European number of documents 0494114 A2; 0585132 A1; 0598624 A1; And 0615285A2), IBM (sees United States Patent (USP) the 5th, 528,222; 5,550,547; 5,521,601; And 5,682, No. 143), and sensation electronics (seeing United States Patent (USP) the 5th, 625, No. 341).The patent content of above-mentioned reference all is included in this.

[0009] current reader and transmitter unit are normally huge, and are not well suited for being merged in such as in the such little low Energy device of wrist-watch.Same, typical 0.1mw is not well suited for being merged in wrist-watch, portable digital-assistant (PDA) to 0.5mw reader power demand, and perhaps other portablely maybe can be worn in the device.

[0010] practical problems that this rfid system faced comprises weak transmit signal energy, large-size and the weight that is associated with some label and sensor, and signal shielding, except that these problems, also has other more abstract problem.A problem is: such fact is arranged, and promptly each place (country) can be controlled in the transmission on the different sections of frequency spectrum in this place.Although exist,, have about forbidding that by this rfid system frequency of utilization transmission is not uncommon usually for different places from place certain consistance (uniformity) to local (country-to-country).Like this, wish to find the transceiver with in frequency place work, this frequency allows this transceiver and the rfid system that is associated is used in a plurality of places.

[0050] Fig. 5 illustrates preferable tag block synoptic diagram.In this embodiment, label should be made up of several members.If label inquired, then passive wake-up circuit 502 provides energy to label.Identification circuit 501 keeps energy decreases, unless label is inquired that this identification circuit 501 is responsible for interrogating signals that decision receives by label and whether is meant this label, and what appropriate responsive should be, if one is necessary words.Crystal 5 00 allows reception/transmission Signal Matching.Whether switch 504 determination datas are received from one or more label sensors, and perhaps it is sent by one or more label sensors.Energy/ signal transformer 505 and 506 allows label to regulate the data-signal rank before transmission and when data are received. Piezoelectric sensor 505 and 507 receives and sends data and request is investigated.Except that any gain amplifier by transformer 505 and 507, LNA 503 also can be used to amplify the introducing data.The front portion of noting LNA has the switch set with receiving mode, its be keep energy always piece only arranged.

[0051] Fig. 6 is the process flow diagram of illustrating preferable label study, investigation and control method.As illustrated in the piece 600 of Fig. 6, each ultrasonic wireless identification tag is preferably to be endowed the baseline concentrator marker in the manufacture process stage, and wherein the baseline concentrator marker is to select from the concentrator marker of one group of one or more previously known.Except that identification (RFID) tag clearly, tag marker also can comprise label construction or functional.As an example, rather than to limit the present invention, the concentrator marker that is endowed label about asset monitoring can comprise prefix or use show such purposes inspection and, and can comprise different prefixes about the label of (in situ monitoring) in monitoring like this.

[0052] when new label is transported to the user, new label and wrist-watch, PDA, perhaps other control device or controller are associated, and this is by being realized to piece 615 illustrated modes of learning by the piece 610 of Fig. 6.As indicated in piece 610, the controller that is associated with new label at first is placed in the label registration, perhaps in the mode of learning.In preferred embodiment, next controller sends to identification request all known base line tag markers, as shown in the piece 611.In another embodiment, the baseline concentrator marker that is associated with specific new label can be printed on the label, be printed on the container that wherein label is transported, perhaps can be by the access of controller function device, and the controller function device can be directly inputted to the tag marker that is associated with new label in the controller.When controller sent the tag identifier request, controller can be monitored and register those identification request is made the responding tags concentrator marker.

[0053] when tag marker that controller has been learnt to be associated with any new label, controller can use concentrator marker to decide tag types.In preferred embodiment, controller can be taken on the controller function device, to verify the tag types of this decision, as safety precaution.When having determined tag types about new label, discrete concentrator marker can be produced by the controller that is associated with this label.In preferred embodiment, so discrete concentrator marker is the concentrator marker unique for controller.As an example, rather than will limit the present invention, each controller according to the present invention's design can have and they associated unique identification devices, and this concentrator marker, and perhaps its part can be used as the part unique tags concentrator marker by the controller assignment.In addition, controller can add the such additional information of character string such as multiword symbol and order generation to the concentrator marker of controller when creating each new tag marker.This can be directed at not only the tag marker unique and unique to all labels to each controller.This process is illustrated by the piece 612 of Fig. 6.

[0054] in case the discrete concentrator marker of system is created, then controller can send to the study id command the new label of appointment.The study id command allows new tag record to be kept at the discrete concentrator marker of the system in the storer in the label.Shown in piece 614, the present invention's use one-time write preferably (write-once) flash memory is to preserve the discrete concentrator marker of system in the label.In another embodiment, but both discrete concentrator marker of saved system of label can be preserved the controller identifier device again, the perhaps encrypted form of controller identifier device, and it is in the one-time write flash memory.Preserve such data and add added security in the one-time write storer, this is because label can not be with other concentrator marker reprogramming.In another embodiment, controller identifier device information can be stored in the recordable memory (rewriteable memory), thereby allows controller cycle to sexually revise the controller identifier device that is kept on the label, and it is potential improves tag security.

[0055] as illustrated in the piece 615, final mode of learning step comprise the new label of checking based on now with disperse concentrator marker and control order is made response of label system associated.If the correct response of label, the controller any parameter that is associated with label of controller function device input that requires preferably is selected, and this is such as alarm limit or alert consitions.Such parameter is selected preferably together with being stored in the controller with the discrete concentrator marker of their system associated.If the incorrect response of label, the controller function device is endowed option, with retry or withdraw from mode of learning.

[0056] in preferred embodiment, about in piece 611 sign each new label and repeatable block 612 to 615.In another embodiment, when new label was associated with controller, piece 610 to 615 can all be repeated at every turn.

[0057] preferable label investigation method is illustrated to piece 624 by the piece 620 of Fig. 6.As illustrated in piece 620, the label investigation is from sending the controller that request sends to specific label with label.As illustrated in piece 631, and as above-mentioned, label sends asks preferably comprising and the discrete concentrator marker of given label system associated, and the controller identifier device.Receiving label that label sends request at first will be included in label and send the discrete concentrator marker of system and system in being kept at tag ram in the request concentrator marker that disperses and compare.If the discrete concentrator marker of system does not match, then label keeps " dormancy " (" asleep "), like this so that do not carry out other action.If the discrete concentrator marker coupling of system, then label can continue to handle.In preferred embodiment, tag processes continues with label, and it will send the controller identifier device that uses in the request at label and compare with the controller identifier device in being kept at tag ram.If the controller identifier device does not match, then label can keep dormancy.By the discrete concentrator marker of controller identifier device and system is compared, label safety can further be strengthened.Yet another embodiment of the present invention is not used the controller identifier device, and this only relies on system's discrete tags concentrator marker, should when broadcast with the decision label.

[0058] send request in case label has determined it should answer label, then label can be answered such request by sending the discrete concentrator marker of its system.If label has inductor, such as, but be not limited to, strain gauge, vibration sensor, glucose watch-dog (glucose monitor), perhaps similar attached, then label also can send sensor data except that the discrete concentrator marker of its system.

[0059], sends the controller that label sends request and will wait for about wanting the predetermined period of time of responsive tags as illustrated in the piece 622.If the label response, then controller can be taked suitable action based on any data of being returned by label, and this comprises the such data of registration so that use later on.If label does not respond, then controller can send warning, and it carries out other suitable action.In addition, as illustrated in piece 623, if label has the inductor that is attached to it, then controller can verify that the inductor reading is in controller function device specified limit.If the inductor reading outside such limit, then can send warning or controller carries out other action.

[0060] as illustrated in the piece 624, then about the discrete concentrator marker of the next system that is associated with controller and repeat the normal mode process.In addition, piece 620 is to piece 624 activity monitorings (active monitoring) that are repeated continuously to allow all labels preferably.In another embodiment, controller can suspend with the tabulation end of the discrete concentrator marker of controller system associated.In another embodiment, controller can suspend in the end of each normal mode process, allowing multi-controller in identical zone, to work, and do not have multi-controller and crosstalk with fully identical frequency work place with its label that is associated or the possibility of other interference.

[0061] shown in piece 630 to 634, according to ultrasonic tag system of the present invention also may command and/or activate on label or the device that is associated with label, this such as, but be not limited to portable delivery of drugs system and about aircraft or about the control system of automobile.As illustrated in piece 630, the label investigation is from sending the controller that request sends to specific label with label.As illustrated in piece 631, and as mentioned above, label sends asks preferably comprising and disperse concentrator marker and controller identifier device to the outgoing label system associated.Receive label that label sends request at first will be included in label send in the request the discrete concentrator marker of system be kept at tag ram in system's concentrator marker that disperses compare.If the discrete concentrator marker of system does not match, then label keeps " dormancy " (" asleep "), like this so that do not carry out other action.If the discrete concentrator marker coupling of system, then label can continue to handle.In preferred embodiment, tag processes continues with label, and its controller identifier device that will be used in the label transmission request is compared with the controller identifier device in being kept at tag ram.If the controller identifier device does not match, then label can keep dormancy.By the discrete concentrator marker of comparison controller concentrator marker and system, label safety can further be strengthened.Yet another embodiment of the present invention is used the controller identifier device really, and this only relies on system's discrete tags concentrator marker, should when broadcast with the decision label.

[0062] send request in case label has determined it should answer label, then label can be answered such request by sending the discrete concentrator marker of its system.If concentrator marker has inductor, such as, but be not limited to, strain gauge, vibration sensor, glucose monitors, perhaps similar attached, then label also can send sensor data except that the discrete concentrator marker of its system.

[0063], sends the controller that label sends request and will wait for about wanting the predetermined period of time of responsive tags as illustrated in the piece 632.If label does not respond, then controller can send warning, and it carries out other suitable action.If the label response, then controller can be taked suitable action based on any data of being returned by label, and this comprises the such data of registration so that use later on.In addition, one receives label response, and preferably after handling any data of being returned by label, controller can order label that order is sent on the label or with device that label is associated on.As an example, rather than will limit the present invention, label available blood glucose measurement (blood glucose measurement) responds, and within the acceptable range whether controller can determine glucose level.If glucose level is outside acceptable scope, then the controller injection of insulin device that is injected into that can order label to make to be associated with label discharges an amount of insulin.

[0064] as illustrated in piece 623, the label that receives order verifies that at first label just is properly handled.Label can determine it whether just using the similar process of using with the request that sends about label and be properly handled.If label determines it not to be properly handled, then label may dormancy.If label determines it just to be properly handled, but then this label implementation controller order.
