And the instruction set among the CPU50 also can be used as a kind of mode of shielding Peripheral Interface 90, particularly, can be by the attribute information (version number of operating system of read operation system, the title of operating system, the copyright information of operating system, information such as needed hardware parameter during operating system) what judge current operation is first operating system or second operating system, if current operation is first operating system, then CPU50 shields the instruction set that Peripheral Interface 90 is supported automatically, make that CPU50 can't compliant peripheral interface 90, thereby shield Peripheral Interface 90 indirectly.If current operation is second operating system, then CPU50 recovers the instruction set to Peripheral Interface 90 supports, makes the CPU50 compatibility to Peripheral Interface 90, thereby makes Peripheral Interface 90 can transmit data.
The memory function of shielding first memory 201, make its convert to can only function mode have multiple.In a certain embodiment, central processing unit 50 is connected with a microswitch (miniature metal-oxide-semiconductor switch), being connected of the access hole control line of this miniature metal-oxide-semiconductor switch and first memory 201 (being the stitch that the data in the circuit diagram of first memory 201 write), when first memory 201 starts, this miniature metal-oxide-semiconductor switch of central processing unit 50 controls cuts off the power supply with the access hole control line, make first memory 201 lose data storage function, thus, the user can't store the data on the specific memory 3 in the electronic installation 1 into by electronic equipment 1.
In addition, also the memory capacity of first memory 201 can be customized to the capacity that just only enough satisfies the normal operation of first operating system and additional storage space can't be provided, thus, even if electronic installation 1 has been carried out the instruction of data long pass in the first memory 201 of electronic installation 1, also can return the miscue instruction because of there not being first memory 201 not have storage space and (namely eject dialog box, prompting does not have storage space, can't carry out storage action).Further, in some cases, the capacity that first operating system is used be one dynamic, for example, (suppose that namely first operating system has 100 functions under the situation of the maximum utilization rate of first operating system, under the situation that these functions are all opened), the capacity of the first memory 201 that first operating system is shared is 1.5G, and under the situation of the minimum utilization rate of first operating system (namely normal to guarantee first operating system except the function that must start), the capacity of the first memory 201 that first operating system is shared is 1.2G, at this moment, in order to guarantee that the user can also move first operating system under the situation of maximum utilization rate, capacity with first memory 201 outfit 1.5G can cover all operating positions that the user uses first operating system like this.Yet, under the process of using first operating system, most of the time can not reach the situation of the maximum utilization rate of first operating system, thus, during first operating system, also have remaining memory capacity, for example, the capacity of the first memory 201 that first operating system is shared is 1.2G, also have the residual capacity of 0.3G, for fear of in residual capacity, storing data, can in the task manager of the operating system first time, monitor the function that starts, obtaining first operating system shared memory capacity of current when operation, thereby calculate remaining memory capacity, afterwards remaining memory capacity is managed, in remaining memory capacity, fill up a certain or polytype data (for example, configuration file), make and win operating system when operation, even if the user wants to store the data of given server 3, can can't not store because first memory 201 will not have other storage area yet.Because remaining memory capacity is dynamic change, when some functions of first operating system are opened, calculate the needed memory capacity of this function, and in remaining memory capacity the deletion some data, with vacating space in remaining memory capacity to the function of this unlatching.
Step S14, central processing unit 50 sending controling instructions are given wireless communication module 20, and the character network configuration that the operating system of winning is set by wireless communication module is connected with given server 3.Given server 3 also can carry out tag control to the data that transfer out, namely when giving electronic installation 1 by data packet transmission, the sequence numbered tag of additional some encryptions (for example, also have Business Name and transmit the date and sequence number that the time is formed), this sequence numbered tag is hidden in packet, electronic installation 1 is when receiving the packet that sends from given server 3, packet all can be with this sequence numbered tag, further, when 1 pair of packet that sends of electronic installation is handled, the label substance of this sequence number will expand automatically, be that sequence numbered tag will comprise user profile and (namely licenses the information that this electronic installation 1 is connected to the user of given server 3, comprise user name and running time etc.), that is to say, to there be the packet of sequence numbered tag to handle to additional, in the sequence numbered tag that must add the user name of electronic installation 1 and running time to encryption, otherwise, can't handle this packet, thus, even if the user has obtained data by electronic installation 1, can obtain also whom data handled by by the mode of deciphering, make things convenient for checking of data, guaranteed traceability and the security of data.
As shown in Figure 4, be the process flow diagram of the preferred embodiment of the electronic installation of the present utility model method that starts second operating system.
Step S20, electronic installation 1 is connected power supply.
Step S21, gear controller 60 connect on the driving switch 40 gear corresponding with second memory 202.Particularly, gear controller 60 is connected shelves C with shelves B.The user can control gear controller by manual mode shelves C is connected with shelves B.The user also can be by RFID reader 72 control gear controllers 60, and then make gear controller 60 control gear C be connected with shelves B, for example, by with I.D. near RFID reader 72, if the identity information on this I.D. is consistent with the identity information of storing in advance on this RFID reader 72, then CPU50 sends instruction to gear controller 60, makes gear controller 60 control shelves C be connected with shelves B.
Step S22, CPU50 communicate with second memory 202 and are connected, and start second operating system on the first memory 202.
Step S23 recovers Peripheral Interface 90.Particularly, the driver with Peripheral Interface in the Peripheral Interface controller 80 can be set to upstate.The microswitch that arranges between Peripheral Interface controller 80 and the Peripheral Interface 90 is connected, made Peripheral Interface 90 connect power supply.Discharge the instruction set of relevant Peripheral Interface 90 among the CPU50, make that CPU50 can the compliant peripheral interface, and support the data-transformation facility of Peripheral Interface 90.
As shown in Figure 5, be whether normally RFID reader that to verify electronic installation reads the information process flow diagram of the preferred embodiment of method.
Step S201, RFID reader 201 is sending interrogating signal to RFID label 74.RFID reader 201 sends interrogating signal to after the RFID label 74, will receive the return signal that transmits from RFID label 74.
Step S202 determines that whether return signal is from RFID label 74.Particularly, RFID reader 72 compares the information in the return signal and the information that is stored in RFID reader 72, if result relatively is identical for the information in the return signal with the information that is stored in RFID reader 72, then this return signal is from RFID label 74, if result relatively is inequality with the information that is stored in RFID reader 72 for the information in the return signal, then this return signal is from other RFID labels.Generally speaking, if having only RFID label 74 around the RFID reader 72, the signal that then returns is from RFID label 74, if around the electronic installation 1 a plurality of RFID labels are arranged, the signal that then returns 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 judges 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) then, RFID reader 72 no longer sends interrogating signal, and flow process enters step S205.
Whether step S205 has received the correct response of RFID label 74 with definite RFID reader 72 according to the return signal quantity of statistics.Generally speaking, if the quantity of return signal is consistent with the number of times of transmission interrogating signal, then to have received the response of RFID label 74 correct for RFID reader 72.In addition, in some cases, because signal transmits the error that occurs, the quantity of the return signal that receives can be not consistent with the number of times that sends interrogating signal, at this moment, if the quantity (for example, 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 had received the correct response of RFID label 74, then to read information normal for RFID reader 72, and this RFID reader 72 can be correct reads information on other RFID label (for example, I.D. card).In some cases, if RFID reader 72 is very approaching with RFID label 74, and direct and RFID, erroneous judgement may appear, then 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 is with the different distance between change modeling RFID reader 72 and the 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 the RFID label 74, can not receive up to RFID reader 72 till 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 return signal less than the attenuation amplitude of setting, show that then this RFID reader 72 does not receive the insufficient sensitivity that enough strong signal or this RFID reader 72 read signal from RFID label 74.
Step S207, according to the result of above-mentioned checking, whether prompting user RFID reader 72 reads information normal.When the attenuation amplitude of return signal during less than the attenuation amplitude set, it is undesired that this RFID reader 72 of prompting user reads information.The mode of prompting is undesired for showing that at touch-screen 90 this RFID reader 72 reads information.When the attenuation amplitude of return signal during more than or equal to the attenuation amplitude set, it is normal that this RFID reader 72 of prompting user reads information.The mode of prompting is normal for showing that at touch-screen 90 this RFID reader 72 reads information.In addition, when drawing RFID reader 72, result verification reads data just often, for avoiding RFID reader 72 when obtaining I.D. card information, to be subjected to the interference of RFID label 74, 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 during less than the attenuation amplitude set, the bright or hummer of warning lamp is sounded, to point out the user these RFID reader 72 cisco unity malfunctions.
As shown in Figure 6, be the process flow diagram of revising the label data in the RFID label of electronic installation.
Step S301 activates RFID label 74.The mode that activates RFID label 74 is RFID reader (not being mounted in the RFID reader 72 on the electronic installation) by the outside during near RFID label 74, and RFID label 74 receives interrogating signal, and produces response, and this moment, the RFID label 74 was activated.The interference of the RFID reader 72 on the electronic installation 1, when the label data on the RFID label 74 is made amendment, 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 the antenna 700, make this RFID read 72 and lose the ability that sends signal).
Step S302, the central processing unit sending controling instruction is given RFID label 74, forbids the data-transformation facility on the RFID label 74.Particularly, store a data modification sign on the described RFID label 74, this data modification sign represents with a character, for example, Y or N, when data modification was masked as Y, the data-transformation facility on the RFID label 74 was normal, that is to say, outside RFID reader can obtain the information on the RFID label 74, when data modification was masked as N, the data-transformation facility on the RFID label 74 was closed, and outside RFID reader can not obtain the information on the RFID label 74.
Step S303, central processing unit 50 request near the RFID reader (i.e. Wai Bu RFID reader) of electronic installation 1 send its only identifier (unique identifier, UID).Described UID has uniqueness, is used for distinguishing different RFID readers.
Step S304 when central processing unit 50 has determined to receive the UID of RFID reader of close electronic installation 1, judges whether to exist the RFID label data corresponding with the UID that receives.Particularly, storage medium in the electronic installation 1 (for example, storage space on first memory 201, the second memory 202) preserves a RFID label data tabulation on, the corresponding RFID label data of UID of a plurality of RFID readers is preserved in described RFID label data tabulation, the corresponding RFID label data of each UID.If have the UID that receives in the tabulation of RFID label data, show that then this UID has corresponding RFID label data, otherwise, if do not have the UID that receives in the tabulation of RFID label data, show that then this UID does not have corresponding RFID label data.
Step S305 is saved in the RFID label data corresponding with UID in the RFID label 74, to replace original label data in the 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 with the data modification sign in the RFID label 74 by N, and RFID label 74 can carry out data transmission afterwards.
Need to prove at last, above embodiment is only unrestricted in order to the technical solution of the utility model 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 make amendment or be equal to replacement the technical solution of the utility model, and not break away from the scope of technical solutions of the utility model.
