And instruction set in CPU50 also can be used as a kind of mode of shielding Peripheral Interface 90, particularly, can pass through the attribute information (version number of operating system of read operation system, the title of operating system, the copyright information of operating system, the information such as needed hardware parameter when operating system) what judge current operation is the first operating system or the second operating system, if current operation is the first operating system, the instruction set that CPU50 automatic shield is supported Peripheral Interface 90, make the CPU50 cannot compliant peripheral interface 90, thereby indirectly shield Peripheral Interface 90.If current operation is the second operating system, CPU50 recovers the instruction set that Peripheral Interface 90 is supported, makes 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), in the time that first memory 201 starts, central processing unit 50 is controlled the power supply of this miniature metal-oxide-semiconductor switch cut-out and access hole control line, make first memory 201 lose data storage function, thus, user cannot store the data in specific memory 3 in 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 meets the normal operation of the first operating system and additional storage space cannot be provided, thus, even if electronic installation 1 has been carried out data long pass to the instruction in the first memory 201 of electronic installation 1, also can return to miscue instruction and (eject dialog box because of not having first memory 201 there is no storage space, prompting does not have storage space, cannot carry out storage action).Further, in some cases, the capacity that the first operating system is used be one dynamic, for example, in the situation of the maximum utilization rate of the first operating system, (suppose that the first operating system has 100 functions, in the situation that these functions are all opened), the capacity of the shared first memory 201 of the first operating system is 1.5G, and when in the situation of the minimum utilization rate of the first operating system (except the function that must start is normal to ensure the first operating system), the capacity of the shared first memory 201 of the first operating system is 1.2G, now, in order to ensure that user can also move the first operating system the maximum utilization rate in the situation that, first memory 201 is equipped with to the capacity of 1.5G, can cover so all service conditions that user uses the first operating system.But, using under the process of the first operating system, most of the time can not reach the situation of the maximum utilization rate of the first operating system, thus, when the first operating system, also have remaining memory capacity, for example, the capacity of the shared first memory 201 of the first operating system is 1.2G, also have the residual capacity of 0.3G, for fear of store data in residual capacity, can in the task manager of operating system for the first time, monitor started function, to obtain the first operating system shared memory capacity of current when operation, thereby calculate remaining memory capacity, afterwards remaining memory capacity is managed, (for example in remaining memory capacity, fill up a certain or polytype data, configuration file), make the first operating system in the time of operation, even if user wants to store the data of given server 3, also can cannot store because first memory 201 will there is no other storage area.Because remaining memory capacity is dynamic change, in the time that some functions of the first operating system are opened, calculate the needed memory capacity of this function, and in remaining memory capacity, delete some data, with vacating space in remaining memory capacity to the function of this unlatching.
Step S14, central processing unit 50 sending controling instructions, to wireless communication module 20, make the character network configuration that the first operating system is set by wireless communication module be connected with given server 3.Given server 3 also can carry out tag control to the data that transfer out, by data packet transmission during to electronic installation 1, the sequence numbered tag of additional some encryptions (for example, also have Business Name and transmit the sequence number that date and time form), this sequence numbered tag is hidden in packet, electronic installation 1 is in the time receiving the packet sending from given server 3, packet all can be brought this sequence numbered tag, further, in the time that electronic installation 1 is processed the packet sending, the label substance of this sequence number will expand automatically, be that sequence numbered tag will comprise user profile and (licenses this electronic installation 1 and be connected to the user's of given server 3 information, comprise user name and running time etc.), that is to say, to process the packet that is attached with sequence numbered tag, the user name of electronic installation 1 and running time must be added in the sequence numbered tag of encryption, otherwise, cannot process this packet, thus, even if user has obtained data by electronic installation 1, also can obtain by the mode of deciphering whom data processed by, facilitate checking of data, traceability and the security of data are guaranteed.
As shown in Figure 4, be the process flow diagram that electronic installation of the present invention starts the preferred embodiment of the method for the second operating system.
Step S20, electronic installation 1 switches on power.
Step S21, gear controller 60 is connected gear corresponding with second memory 202 on driving switch 40.Particularly, gear controller 60 is connected shelves C with shelves B.User can be connected shelves C by manual mode control gear controller with shelves B.User also can control gear controller 60 by RFID reader 72, and then make gear controller 60 control gear C with shelves a B be connected, for example, by by I.D. near RFID reader 72, if the identity information on this I.D. is consistent with the pre-stored identity information on this RFID reader 72, CPU50 sends instruction to gear controller 60, makes gear controller 60 control shelves C and is connected with shelves B.
Step S22, CPU50 communicates and is connected with second memory 202, starts the second operating system on first memory 202.
Step S23, recovers Peripheral Interface 90.Particularly, the driver of Peripheral Interface in Peripheral Interface controller 80 can be set to upstate.The microswitch arranging between Peripheral Interface controller 80 and Peripheral Interface 90 is connected, Peripheral Interface 90 is switched on power.Discharge the instruction set about Peripheral Interface 90 in CPU50, make the CPU50 can compliant peripheral interface, and support the data-transformation facility of Peripheral Interface 90.
As shown in Figure 5, be the whether normally process flow diagram of the preferred embodiment of method of RFID reader reading information of checking electronic installation.
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 transmitting from RFID label 74.
Step S202, determines 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 is relatively 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 is relatively 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 RFID reader 72 only has RFID label 74 around, the signal returning is from RFID label 74, if electronic installation 1 has multiple RFID labels around, the signal returning is not necessarily from RFID label 74.
Step S203, RFID reader 72 is added up the return signal quantity from 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 user sets.For example, suppose that the number of times that 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 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 with to send the number of times of interrogating signal consistent, to have received the response of RFID label 74 correct for RFID reader 72.In addition, in some cases, because signal transmits the error occurring, the quantity of the return signal receiving 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 that RFID reader 72 has received the correct response of RFID label.Generally speaking, in the time that RFID reader 72 has received the correct response of RFID label 74, RFID reader 72 reading informations are normal, and what this RFID reader 72 can be correct reads for example, information on other RFID label (, I.D. card).In some cases, if RFID reader 72 is very approaching with RFID label 74, and direct and RFID, may there is erroneous judgement, 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, shows 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.In the time that 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 for to show that on touch-screen 90 these RFID reader 72 reading informations are undesired.In the time that 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 for 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 in the time obtaining I.D. card information, central processing unit 50 (for example cuts out RFID label 74, disconnect the antenna of RFID label 74 inside), this RFID label 74 is quit work.The mode of prompting can also be to send 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 in the time that the attenuation amplitude of return signal is less than the attenuation amplitude of setting, bright or the hummer of warning lamp is sounded, to point out user these RFID reader 72 cisco unity malfunctions.
As shown in Figure 6, be the process flow diagram of label data in the RFID label of amendment electronic installation.
Step S301, activates 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, RFID label 74 receives interrogating signal, and produce response, now RFID label 74 is activated.For fear of the interference of the RFID reader 72 on electronic installation 1, in the time that 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, or cut off being connected between RFID reader 72 and antenna 700, make this RFID read 72 abilities that lose transmitted signal).
Step S302, central processing unit sending controling instruction, to RFID label 74, is forbidden the data-transformation facility on RFID label 74.Particularly, on described RFID label 74, store a data modification mark, this data modification mark represents with a character, for example, Y or N, in the time that 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, in the time that 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, determines while having received the UID of RFID reader of close electronic installation 1 when central processing unit 50, judges whether to exist the RFID label data corresponding with the UID receiving.Particularly, storage medium in electronic installation 1 (for example, storage space on first memory 201, second memory 202) on preserve the list of a RFID label data, the corresponding RFID label data of UID of multiple 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 receiving in the list of RFID label data, show that this UID has corresponding RFID label data, otherwise, if there is not the UID receiving in the list of RFID label data, show that this UID does not have corresponding RFID label data.
Step S305, is saved in the RFID label data corresponding with UID in RFID label 74, to replace label data original 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 mark 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 this aspect is had been described in detail with reference to preferred embodiment, 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 depart from the scope of technical solution of the present invention.
