Fig. 3 is the process flow diagram of the preferred embodiment of the present invention's method of by ID (identity number) card information, electronic installation being carried out release.
Step S10 when electronic installation 1 switches on power, shows starting-up interface 901 on touch-screen 90.By unwinding interface 901, the user selects first memory 201 or the second memory 202 that will start.
Step S20, while selecting to carry out the storer of release by ID (identity number) card information on starting-up interface 901 as the user, whether checking RFID reader 72 reading informations are normal.In this preferred embodiment, because electronic installation 1 comprises first memory 201 and second memory 202, the described storer that need to carry out release by ID (identity number) card information can be in first memory 201 and second memory 202, can be also two (being that first memory 201 and second memory 202 all need to carry out release by ID (identity number) card information).If first memory 201 need to carry out release by ID (identity number) card information, and second memory 202 does not need ID (identity number) card information to carry out release, when the user clicks square frame 9020, RFID reader 72 is verified, whether normal with checking RFID reader 72.And the user does not need RFID reader 72 is verified while clicking square frame 9030, directly notify gear controller 60 that shelves C is connected with a shelves B, thereby make central processing unit 50 and second memory 202 communication connections, startup second memory 202.If first memory 201 and second memory 202 all need to carry out release by ID (identity number) card information, no matter the user clicks square frame 9020 or square frame 9030 on starting-up interface 901, all RFID reader 72 is verified, whether normal with checking RFID reading information.
Step S30, if RFID reader 72 reading informations are normal, show the I.D. interface 902 (shown in Fig. 9) of swiping the card on touch-screen 90, the prompting user by the I.D. card near I.D. swipe the card interface 902 ID (identity number) card information received on the I.D. cards by RFID reader 72.This I.D. swipe the card interface 902 also for example, by eye-catching word (, please brush I.D.) or picture with the prompting user by the I.D. card near this I.D. interface 902 of swiping the card, with the ID (identity number) card information received in these I.D. cards by RFID reader 72.In this preferred embodiment, for fear of arbitrarily other people carry out release by brush I.D. card to the storer of electronic installation 1, RFID reader 72 can be set the ID (identity number) card information of the I.D. card that can only read some or several specific people.
Whether step S40, send to ID (identity number) card information verification system 3 by the ID (identity number) card information received by wireless communication module 20, effective to verify this ID (identity number) card information.After ID (identity number) card information verification system 3 receives the ID (identity number) card information sended over, data message in the database of the ID (identity number) card information that this is received and ID (identity number) card information verification system 3 is compared, if there are data consistent with the ID (identity number) card information sended in the database of ID (identity number) card information verification system 3, this ID (identity number) card information sended over is effective, flow process enters step S50, otherwise, if consistent with the ID (identity number) card information sended over without any data in the database of ID (identity number) card information verification system 3, this ID (identity number) card information sended over is invalid, on display screen 90, show that this I.D. is invalid.In addition, the checking mode can also with pre-stored storage medium on electronic installation 1 (for example, the storage space of first memory 201 or second memory 202 or starting-up interface processor 10) ID (identity number) card information is compared, if identical with pre-stored ID (identity number) card information, flow process enters step S50, otherwise, on display screen 90, show that invalid or this I.D. of this I.D. does not have authority.
Step S50, central processing unit 50 sending controling instructions are to gear controller 60, and gear controller 60 is controlled shelves C, makes grade C be connected with the gear of corresponding stored device, central processing unit 50 communicates connection with corresponding storer, starts the operating system on the corresponding stored device.Particularly, if what the user started is first memory 201, central processing unit 50 sending controling instructions are to gear controller 60, and gear controller 60 is controlled shelves C and is connected with shelves A, thereby make central processing unit 50 communicate and be connected with first memory 201, thereby start first memory 201.If what the user started is second memory 202, central processing unit 50 sending controling instructions are to gear controller 60, gear controller 60 is controlled shelves C and is connected with shelves B, thereby makes central processing unit 50 communicate and be connected with second memory 202, thereby starts second memory 202.
Fig. 4 is the refinement process flow diagram of the step S20 that in Fig. 3, the RFID reader verified.
Step S201, RFID reader 201 is sending interrogating signal to RFID label 74.RFID reader 201 sends interrogating signal to after RFID label 74, will receive the return signal transmitted from RFID label 74.
Step S202, determine that whether return signal is from RFID label 74.Particularly, RFID reader 72 compares the information in return signal and the information that is stored in RFID reader 72, if result relatively is that the information in return signal is identical with the information that is stored in RFID reader 72, this return signal is from RFID label 74, if result relatively is that the information in return signal is not identical with the information that is stored in RFID reader 72, this return signal is from other RFID labels.Generally speaking, if only have RFID label 74 around RFID reader 72, the signal returned is from RFID label 74, if around electronic installation 1, a plurality of RFID labels are arranged, the signal returned is not necessarily from RFID label 74.
Step S203, RFID reader 72 statistics are from the return signal quantity of RFID label 74.
Step S204, judge whether poll (polling) finishes.Judge that the mode whether poll finishes is to judge whether the number of times that sends interrogating signal reaches the number of times that the user sets.For example, suppose that the number of times that the user sets is 10 times, if send this time arriving 10 times of interrogating signal, end of polling(EOP), RFID reader 72 no longer sends interrogating signal, and flow process enters step S205.
Step S205, according to the statistics return signal quantity to determine whether RFID reader 72 has received the correct response of RFID label 74.Generally speaking, if the quantity of return signal is consistent with the number of times that sends interrogating signal, to have received the response of RFID label 74 correct for RFID reader 72.In addition, in some cases, because signal transmits the error occurred, the quantity of the return signal received can be not consistent with the number of times that sends interrogating signal, now, for example, if the quantity (, between 8 to 10 times) within certain scope of the return signal of statistics, also can be considered the correct response that RFID reader 72 has received the RFID label.Generally speaking, when RFID reader 72 has received the correct response of RFID label 74, RFID reader 72 reading informations are normal, for example, the information on other RFID label (, I.D. card) that reads that this RFID reader 72 can be correct.In some cases, if RFID reader 72 is very approaching with RFID label 74, and direct and RFID, erroneous judgement may appear, can be by an analog chip (not shown) be set between RFID reader 72 and RFID label 74, this analog chip return signal that can decay, with the different distance between change modeling RFID reader 72 and RFID label 74, to obtain RFID reader 72 by the attenuation amplitude of this analog chip decay return signal.The mode of decay is by the distance between change modeling RFID reader 72 and RFID label 74, until RFID reader 72 can not receive the return signal of RFID label, in the process of decay, obtains the attenuation amplitude of return signal.
Step S206, relatively the attenuation amplitude of return signal and the attenuation amplitude of setting, judge whether the attenuation amplitude of return signal is equal to or greater than the attenuation amplitude of setting.If the attenuation amplitude that is less than setting of return signal, show that this RFID reader 72 does not receive the insufficient sensitivity of enough strong signal or these RFID reader 72 read signals from RFID label 74.
Step S207, according to the result of above-mentioned checking, whether prompting user RFID reader 72 reading informations are normal.When the attenuation amplitude of return signal is less than the attenuation amplitude of setting, these RFID reader 72 reading informations of prompting user are undesired.The mode of prompting is to show that on touch-screen 90 these RFID reader 72 reading informations are undesired.When the attenuation amplitude of return signal is more than or equal to the attenuation amplitude of setting, these RFID reader 72 reading informations of prompting user are normal.The mode of prompting is to show that on touch-screen 90 these RFID reader 72 reading informations are normal.In addition, when result verification show that RFID reader 72 reading out datas are when normal, for avoiding RFID reader 72 to be subject to the interference of RFID label 74 when obtaining I.D. card information, central processing unit 50 (for example cuts out RFID label 74, disconnect the antenna of RFID label 74 inside), make this RFID label 74 quit work.The mode of prompting can also be to send the SMS notification user by wireless sending module 20.In addition, electronic installation 1 can also be installed warning lamp or hummer (for example, red light), if when the attenuation amplitude of return signal is less than the attenuation amplitude of setting, bright or the hummer of warning lamp is sounded, with these RFID reader 72 cisco unity malfunctions of prompting user.
Fig. 5 is the process flow diagram of revising the label data in the RFID label in Fig. 2.
Step S301, activate RFID label 74.The mode that activates RFID label 74 is by outside RFID reader (not being mounted in the RFID reader 72 on electronic installation) during near RFID label 74, and RFID label 74 receives interrogating signal, and produces response, and now RFID label 74 is activated.Interference for fear of the RFID reader 72 on electronic installation 1, when the label data on RFID label 74 is modified, central processing unit 50 (for example cuts out RFID reader 72, cut off the power supply of RFID reader 72, perhaps cut off being connected between RFID reader 72 and antenna 700, make this RFID read 72 abilities that lose transmitted signal).
Step S302, the central processing unit sending controling instruction, to RFID label 74, is forbidden the data-transformation facility on RFID label 74.Particularly, store a data modification sign on described RFID label 74, this data modification sign means with a character, for example, Y or N, when data modification is masked as Y, the data-transformation facility on RFID label 74 is normal, that is to say, outside RFID reader can obtain the information on RFID label 74, when data modification is masked as N, the data-transformation facility on RFID label 74 is closed, and outside RFID reader can not obtain the information on RFID label 74.
Step S303, central processing unit 50 requests send its only identifier (unique identifier, UID) near the RFID reader (being outside RFID reader) of electronic installation 1.Described UID has uniqueness, for distinguishing different RFID readers.
Step S304, when central processing unit 50 is determined the UID of the RFID reader that has received close electronic installation 1, judge whether to exist the RFID label data corresponding with the UID received.Particularly, storage medium in electronic installation 1 (for example, storage space on first memory 201, second memory 202 or starting-up interface processor 10) preserve the list of a RFID label data on, the corresponding RFID label data of UID of a plurality of RFID readers is preserved in the list of described RFID label data, the corresponding RFID label data of each UID.If there is the UID received in the list of RFID label data, show that this UID has corresponding RFID label data, otherwise, if do not have the UID received in the list of RFID label data, show that this UID does not have corresponding RFID label data.
Step S305, RFID label data that will be corresponding with UID is saved in RFID label 74, to replace original label data in RFID label 74.
Step S306, central processing unit 50 is opened the data-transformation facility of RFID label 74.Particularly, central processing unit 50 is revised as Y by the data modification sign in RFID label 74 by N, and RFID label 74 can carry out data transmission afterwards.
Finally it should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment, this aspect is had been described in detail, those skilled in the art are to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not break away from the scope of technical solution of the present invention.
