Further, in second embodiment of the invention described above, various distortion can be carried out further in the scope not departing from purport of the present invention and technological thought.Below this variation is described.
(1) inquiry again when accessing unsuccessfully
That is, obtaining messaging parameter and tag attributes parameter as mentioned above and all rfid circuit element T with box 100 will started 0when communication, when accessing unsuccessfully, because the parameter information obtained originally is likely wrong, therefore once again to rfid circuit element T 0the inquiry for confirming is carried out in side.
Figure 23 be represent form this variation pith, the process flow diagram of label information read step that control circuit 30 is implemented, be the figure of the Figure 21 be equivalent in above-mentioned second embodiment.
In the flow process shown in Figure 23, be provided with the step S170 that step S170A substitutes Figure 17.That is, in step S160, to suspect exist communication bad time number of retries count variable N=5 time when failure (carried out five communication experiments but), proceed to step S170A, then judge process.
Figure 24 is the process flow diagram representing that this judges the detailed step processed again.
The rate-determining steps of Figure 24 and the tag class judgment processing steps of above-mentioned Figure 20 comparatively similar.That is, first in newly-installed step S21A, in the device side storage unit such as RAM, store preservation communication protocol number P, access frequency number F is read at alternative steps S21.
Afterwards, step S22 ~ step S32 is identical with Figure 20.That is, the value of " TX_PWR " signal is set as relatively large predetermined value, " Ping " order is outputted to signal processing circuit 22, urges the rfid circuit element T being positioned at addressable scope 0reply, be taken into the answer signal of reception, judge whether at least to achieve a correct ID.When good answer signal cannot be obtained, in step S26, suitably change frequency number F and protocol number P, turn back to step S23 once again, repeat same step.When after F and P that trial is all, (25 kinds of F, P=1 in the above example ~ 5) also cannot obtain good answer signal, output error display, carries out the display of reading unsuccessfully (mistake).The rfid circuit element T of any one and box 100 in the combination of P, F 0communication protocol and access frequency consistent time, meet the judgement of step S25, the same with Figure 20, in step s 32, obtain and the rfid circuit element T returning this response signal according to the response signal (answer signal) of this reception 0corresponding messaging parameter.
Afterwards, at alternative steps S33 in newly-installed step S33A, the communications parameter information this obtained is stored into (or be stored into above-mentioned terminal 5 or normal computing machine 6 via telecommunication circuit 31 and communication line 3, be stored in routing server 4 or information server 7 further) in RAM, carry out covering update process (haveing nothing to do with storage content so far, even identical value also will upgrade).
Afterwards, step S34 ~ step S37 is the same with Figure 20, the value of " TX_PWR " signal is returned to required minimal predetermined value, determines the rfid circuit element T returning above-mentioned answer signal 0, " ScrollAllID " order is outputted to signal processing circuit 22, and urges the rfid circuit element T of access object 0reply, be taken into the rfid circuit element T from correspondence 0the answer signal sent, and obtain and return the rfid circuit element T of this answer signal 0corresponding tag attributes parameter.
Afterwards, at alternative steps S38 in newly-installed step S38A, the attribute parameter information this obtained is stored into (or be stored into above-mentioned terminal 5 or normal computing machine 6 via telecommunication circuit 31 and communication line 3, be stored in routing server 4 or information server 7 further) in RAM, carry out covering update process (to have nothing to do with storage content so far, even identical value also will upgrade), and terminate this flow process, transfer to the step S180 of above-mentioned Figure 23.
In above content, the step S140 of the flow process shown in Figure 23, step S150, step S160 are equivalent to the judging unit described in each technical scheme, after information transmitting unit executes access with the send mode of the control based on sending controling unit, whether successfully judge the access of IC circuit part; Step S170A is equivalent to confirm command sending unit again, when judging to access unsuccessfully by this judging unit, confirming command signal again by what be used for confirming again the tag attributes parameter of rfid circuit element or messaging parameter, be sent to label-side antenna non-contactly via device side antenna.
Further, receive and identify in step S24 and step S25 from rfid circuit element T 0communications parameter information and tag attributes parameter information be equivalent to the 5th parameter information, acceptance division 33 configuration information receiving element again, by with according to confirming the tag attributes parameter that command signal is read by IC circuit part or relevant the 5th parameter information of messaging parameter again, received by device side antenna non-contactly via label-side antenna, and read in.
Further, the step S33A of the flow process shown in Figure 24 and step S38A, is equivalent to the renewal control module parameter information in the storage unit of device side being updated to the 5th parameter.
Further, the above above-mentioned steps S2 to performing as control circuit 30 label information access an example, from rfid circuit element T 0 iC circuit part 151 flow process that reads the step of wireless tag information carried out example, and in the wireless tag information write of other examples of accessing as label information, step that can certainly be same is carried out.
In this variation as constructed as above, with the send mode of the control based on control circuit 30, to rfid circuit element T 0 iC circuit part 151 conduct interviews after, in the step S140 ~ step S160 of Figure 23, judge this access whether success.When being judged as accessing failed, sending in step S170A and confirming command signal again, received by acceptance division accordingly and read in the messaging parameter/tag attributes parameter information read from IC circuit part 151.And control circuit 30 is in the step S33A and step S38A of Figure 24, regardless of the storage content in the device side storage unit such as RAM so far, be all the above-mentioned parameter information read in by this storage information updating.So, though the tag attributes parameter read originally, communications parameter information because of some reason wrong time (misreading), upgrade time also recoverable be correct information.
Particularly, now described above, in the step S23 of Figure 24, in generation as the ScrollAllID signal confirming command signal again and when sending, in step S21A, first generate signal according to the messaging parameter (agreement P and frequency F) stored in the device side storage unit such as RAM so far.Further, from the empirical value in this past in step S26A, signal is generated according to the messaging parameter different from it further.Due to the empirical value with reference to the past so far, therefore at least with when making above-mentioned messaging parameter random and to generate ScrollAllID signal compare, the probability that finally can obtain correct messaging parameter improves, or can make the time advance of acquisition.
(2) Automatic inquirying when power supply is connected
In the above-described 2nd embodiment, as illustrated in the step S32 of the flow process at Figure 20 and step S37, as device side storage unit, the communication obtained/tag attributes parameter information is stored in RAM in control circuit 30 etc., but be not limited thereto, also can be stored into separately the non-volatile memory cells (so-called EEPROM etc.) that (in or beyond control circuit 30) is arranged.
In this case, even if also storage content can be preserved due to deenergization, therefore as mentioned above, the information of the communication/tag attributes parameter temporarily stored can also be read when power supply is connected.
Figure 25 is the control flow of " tag class judgement " step of the step S1 being equivalent to Figure 15 of by control circuit 30 being undertaken corresponding with this variation, is the figure being equivalent to above-mentioned Figure 20.
In fig. 25, as mentioned above, when power supply becomes connection from off-state, this flow process is namely started.The rate-determining steps of this flow process and the label of the Figure 24 described in above-mentioned (1) judge that the step processed is comparatively similar again.That is, first in newly-installed step S21B at alternative steps S21A, as mentioned above, read and stored the communication protocol number P, the access frequency number F that are kept at the non-volatile memory cells such as EEPROM.
Afterwards, step S22 ~ step S38A is the same with Figure 24, and the value of " TX_PWR " signal is set as relatively large predetermined value, " Ping " order is outputted to signal processing circuit 22, urges the rfid circuit element T being positioned at addressable scope 0reply, be taken into the answer signal of reception, judge whether at least to achieve a correct ID.When good answer signal cannot be obtained, suitably change frequency number F and protocol number P, when good answer signal also cannot be obtained after attempting all F and P, carry out the display of reading unsuccessfully (mistake).The rfid circuit element T of any one and box 100 in the combination of P, F 0communication protocol and access frequency consistent time, obtain and the rfid circuit element T returning this response signal according to the response signal (answer signal) of this reception 0corresponding messaging parameter, and be stored into (or be stored into above-mentioned terminal 5 or normal computing machine 6 via telecommunication circuit 31 and communication line 3, be stored in routing server 4 or information server 7 further) in EEPROM or RAM, carry out covering update process (haveing nothing to do with storage content so far, even identical value also will upgrade).Afterwards, the value of " TX_PWR " signal is returned to relatively little predetermined value, determine the rfid circuit element T returning above-mentioned answer signal 0, export " ScrollAllID " signal and urge reply, being taken into the answer signal of transmission, obtaining and return the rfid circuit element T of this answer signal 0corresponding tag attributes parameter, carries out above-mentioned identical covering update process.
Afterwards, after step S38A terminates, terminate this flow process, move to above-mentioned steps S2, carry out the access (reading or write) of wireless tag information.
In foregoing, " Ping " signal sent in the step S23 of the flow process shown in Figure 25 is equivalent to the initial confirmation command signal described in each technical scheme, for when power supply is connected, initial tag attributes parameter or the messaging parameter confirming rfid circuit element; The sending part 32 sending this signal forms and initially confirms command sending unit, and it will initially confirm that command signal is sent to label-side antenna non-contactly via device side antenna.
Further, receive and identify in step S24 and S25 from rfid circuit element T 0communications parameter information and tag attributes parameter information be equivalent to the 6th parameter information; Acceptance division 33 forms initial information receiving element, by six parameter information relevant with the tag attributes parameter read by IC circuit part according to initial confirmation command signal or messaging parameter, received by device side antenna non-contactly via label-side antenna, and read in.
Further, the step S33A of the flow process shown in Figure 25 and step S38A, is equivalent to the renewal control module parameter information in the storage unit of device side being updated to the 6th parameter.
In this variation, often when the power is turned on, sending part 32 sends as the initial Ping signal confirming command signal, accordingly from rfid circuit element T 0 iC circuit part 151 read messaging parameter/tag attributes parameter information received by acceptance division 33 and read in.And control circuit 30 is in the step S33A and step S38A of Figure 25, regardless of the storage content in the device side storage unit such as EEPROM or RAM so far, be all the above-mentioned parameter information read in by this storage information updating.So; often when the power is turned on; regardless of the storage content of said apparatus side storage unit so far, the parameter information normalization in the storage unit of device side (correct when mistake reads, confirm during normal storage again) all can be made effectively.
And, as mentioned above, in the step S23 of Figure 25, at the Ping signal generated as initial confirmation command signal and when sending, in step S21B, first generate signal according to the messaging parameter (agreement P and frequency F) stored in the non-volatile apparatus side storage unit such as EEPROM so far.Further, from the empirical value in this past in step S26A, signal is generated according to the messaging parameter different from it further.Due to the empirical value with reference to the past so far, therefore at least with when making above-mentioned messaging parameter random and to generate Ping signal compare, the probability that finally can obtain correct messaging parameter improves, or can make the time advance of acquisition.
Further, also can judge according to the kind such as making the situation of the lid open-close that above-mentioned framework 9 is arranged carry out label because box 100 changes.In this case, when detecting that lid is opened and closes by the above-mentioned lid open-close detection sensor 19 shown in Fig. 2, the flow process of above-mentioned Figure 25 is started.
(3) the sharing/combine of sensor-based detection and not sensor-based detection
That is, in the above-described first embodiment, to messaging parameter (the electric wave frequency, communication protocol etc. that use in radio communication) i.e. tag attributes parameter (rfid circuit element T 0the sensitivity of antenna 152, the memory span of IC circuit part 151, adhering element T 0band 101 wide, band 101 on elements T 0configuration space etc.) both, detected by the detected portion identifier 190A ~ D of sensor 20 from box 100, and in the above-described 2nd embodiment, both messaging parameter and tag attributes parameter are by rfid circuit element T 0non-contacting radio communication detect and obtain.
Therefore, as its buffering technique, the part being detected this messaging parameter and tag attributes parameter by sensor can be considered, remainingly to be detected by radio communication.Below two examples are described.
(3-1) detect messaging parameter with sensor, use radio communication tags detected property parameters
Figure 26 be represent as this variation pith, the process flow diagram of rate-determining steps (being equivalent to the step S1 in Figure 15) that tag class that control circuit 30 performs judges.
As shown in figure 26, this rate-determining steps is equivalent to the control flow (identical step is marked with identical step number) of the control flow of the Figure 16 being combined with above-mentioned first embodiment and Figure 20 of the second embodiment.
Namely, first in S11, the detection signal of the detected portion 190 (only forming communications parameter information in this case in identifier 190A ~ D) of the box 100 that input (identification) is detected by the parameter detecting sensor 20 illustrated in the above-described first embodiment, afterwards in step s 12 according to the detection signal detected in above-mentioned steps S11, carry out predetermined process and (comprise computing as required, analyze, extract), thus in the parameter information represented by identifier 190A ~ D, obtain above-mentioned messaging parameter (the electric wave frequency that radio communication uses in step s 12, communication protocol etc.) after, in step s 13 this communications parameter information to be stored in RAM (or be stored into above-mentioned terminal 5 or conventional computer 6 via telecommunication circuit 31 and communication line 3, and then be stored in routing server 4 or information server 7).
Afterwards, proceed to step S35, the same with the second embodiment, determine predetermined rfid circuit element T 0, in the mode consistent with the messaging parameter obtained in step S12 before, " ScrollID " order is outputted to signal processing circuit 22.In signal processing circuit 22, generate " ScrollID " signal as visit information accordingly, and be sent to the rfid circuit element T of access object via high-frequency circuit 21 0, urge and replying.And in step S36, receive from the rfid circuit element T corresponding with above-mentioned " ScrollID " signal via antenna 14 0the answer signal sent, and be taken into via high-frequency circuit 21 and signal processing circuit 22.
Further, in step S37, obtain and return the rfid circuit element T of this answer signal 0corresponding tag attributes parameter (rfid circuit element T 0the sensitivity of antenna 152, the memory span of IC circuit part 151, adhering element T 0band 101 wide, band 101 on elements T 0configuration space etc.), in step S38, this tag attributes parameter information is stored into (or be stored into above-mentioned terminal 5 or conventional computer 6 via telecommunication circuit 31 and communication line 3, be stored in routing server 4 or information server 7 further) in the identical RAM of above-mentioned S12, and process ends.
So, after " the tag class determining step " that be equivalent to the step S1 shown in Figure 15 terminates, step S2 is proceeded to.
In above content, sensor 20 forms the 3rd information detecting unit described in each technical scheme, detects the messaging parameter according to the rfid circuit element of correspondence and the 3rd parameter information be formed on box; Sending part 32 forms and confirms command sending unit, it is according to the 3rd parameter information detected by the 3rd information detecting unit, to the confirmation command signal of the tag attributes parameter confirming rfid circuit element be used for, be sent to label-side antenna non-contactly via device side antenna.
Further, acceptance division 33 forms confirmation receiving element, and it is by four parameter information relevant with the tag attributes parameter read by IC circuit part according to confirming command signal, is received non-contactly, and read in via label side antenna by device side antenna.
In this variation, the messaging parameter of the identifier 190A ~ D formed in box 100 is detected by sensor 20, as confirming that the ScrollAllID signal of command signal is sent to antenna 152 from sending part 32 accordingly, tag attributes parameter information corresponding with it reads from IC circuit part 151, and is received by acceptance division 33.Consequently, according to this tag attributes parameter information and the messaging parameter that detected by sensor 20 before, control circuit 30 controls send mode, with from the tag attributes parameter of sending part 33 or messaging parameter consistent.
So, in this variation, the same with first and second embodiment above-mentioned, even if had rfid circuit element T 0relevant tag attributes parameter, the mutually different multiple box 100 of messaging parameter suitably when use is changed in the handling of box cradle portion, also can utilize the rfid circuit element T with each box 100 0corresponding optimal parameter, rapidly and easily carry out information communication.That is, no matter the kind of box 100 (in other words as the rfid circuit element T of communication object 0kind) how, all can rapidly and be easily set as communicable state.Consequently, can guarantee the rfid circuit element T in box 100 0successfully conduct interviews action.
(3-2) detection messaging parameter is shared by sensor and radio communication
Figure 27 is the process flow diagram of the rate-determining steps (being equivalent to the step S1 in Figure 15) that represent the pith of this variation, that control circuit 30 performs tag class judges.
As shown in figure 27, in this rate-determining steps, in the step S12 shown in Figure 26 of the variation of above-mentioned (3-1) and S13, detect/obtain a part (being protocol information in this embodiment) for messaging parameter, remaining (being access frequency in this embodiment) rate-determining steps according to the Figure 20 in the second embodiment is before carried out detecting/obtaining (identical step is marked with identical step number).
Namely, first in S11, the detection signal of the detected portion 190 (only forming communications parameter information in this case in identifier 190A ~ D) of the box 100 that input (identification) is detected by the parameter detecting sensor 20 illustrated in the above-described first embodiment, afterwards based in the step S12 ' of step S12, according to the detection signal detected in above-mentioned steps S11, carry out predetermined process and (comprise computing as required, analyze, extract), thus after obtaining the communication protocol shown in identifier 190A ~ D, based in the step S13 ' of step S13, this communication protocol information to be stored in RAM (or be stored into above-mentioned terminal 5 or conventional computer 6 via telecommunication circuit 31 and communication line 3, and then be stored in routing server 4 or information server 7).
Then, proceed to the step S21 ' based on step S21, establish frequency number F=1 as initial value.
Step S22 afterwards ~ S25 is the same with Figure 20 of above-mentioned second embodiment, sends " ScrollAllID " signal, receive and be taken into the rfid circuit element T in addressable scope after the value of " TX_PWR " signal being set as relatively large predetermined value 0answer signal, judge whether at least to achieve a correct ID.
Rfid circuit element T in access frequency (frequency number F=1) now with box 100 0communication protocol and frequency inconsistent time, cannot answer signal be obtained, therefore not meet the judgement of step S25, in step S29, add 1 to frequency number F, turn back to step S23 through step S30.Further, when cannot obtain good answer signal in step S24 and step S25, ground, F=1 → 2 →...→ 5 increases number, repeats step S23 ~ step S30 simultaneously.To F=5, increase frequency number when still cannot obtain good answer signal, meet the judgement of step S30, proceed to step S31, carry out above-mentioned reading failure (mistake) display.
F=1 ~ 5 any one under, time consistent with the access frequency of the rfid circuit element T0 of box 100, obtain good answer signal, meet the judgement of step S25, proceed to the step S32 ' based on step S32.
In step S32 ', according to the response signal received in above-mentioned steps S24 (answer signal), carry out predetermined process (comprising computing, analysis, extraction etc. as required), thus obtain and replying the rfid circuit element T of this response signal 0after the frequency information of the electric wave used in corresponding (in other words corresponding with box 100) radio communication, based in the step S33 ' of step S33, this frequency information is stored into (or be stored into above-mentioned terminal 5 or conventional computer 6 via telecommunication circuit 31 and communication line 3, be stored in routing server 4 or information server 7 further) in RAM.
Step S34 afterwards ~ step S38 is identical with Figure 20, and therefore the description thereof will be omitted.
Terminate to step S38 like this, when the step S1 shown in Figure 15 " tag class determining step " terminate after, equally proceed to step S2 with above-mentioned.
In this variation, the same with first and second embodiment above-mentioned and each variation, due to the rfid circuit element T that box has finally can be obtained 0tag attributes, messaging parameter, even if therefore when multiple boxes 100 different from each other for this parameter suitably box cradle portion handling change use, also can utilize the rfid circuit element T with each box 100 0corresponding optimal parameter, rapidly and easily carry out information communication.That is, no matter the kind of box 100 (in other words as the rfid circuit element T of communication object 0kind) how, all can rapidly and be easily set as communicable state.Consequently, can guarantee the rfid circuit element T in box 100 0successfully conduct interviews action.
