Description

  The present invention relates to a writing method and writing system for unique information, and more particularly to a writing method and writing system for unique unique information such as a MAC address assigned to an electronic device such as an electronic computer.

  Generally, an electronic device such as an electronic computer is given unique unique information in order to identify the device. For example, in order to construct a network using a plurality of electronic computers, each of the plurality of electronic computers needs to have different unique information such as a MAC address.

  For this reason, electronic devices such as electronic computers need to have unique unique information to be registered written in a ROM or the like held by the devices, and are easy to understand for producers. In order to do so, it is also necessary to manage the written product after physically writing the unique information.

  Conventionally, one of the two methods has been adopted as a method for writing unique information to write unique information to a ROM and mount the ROM on an electronic device such as an electronic computer so that the electronic device has unique unique information. Has been done.

  FIG. 8 is a diagram for explaining a first method for writing unique information according to the prior art (in the example described, a MAC address is used as unique information), and FIG. 9 is a diagram illustrating the implementation of the method shown in FIG. It is a figure explaining the work procedure to do. The first method described here is a method in which unique unique information to be registered is written into the ROM using a ROM writer, and then the ROM into which the unique information is written is mounted on an electronic device such as an electronic computer. .

  The method shown in FIG. 8 uses a ROM writer 7 having a dedicated program 8. The dedicated program 8 is a program that is stored in the ROM writer 7 and outputs unique information (MAC address A) 1 to be uniquely registered in the electronic device (in this case, the electronic computer 2). The unique information 1 is written in the attached ROM 6.

  As shown in FIG. 9, the work procedure when using the ROM writer 7 as described above is as follows. First, the ROM 6 is directly attached to the ROM writer 7, and the unique information 1 to be registered in the ROM 6 is stored in the dedicated program 8. After performing the procedure (step A1) of writing using the, remove the ROM 6 that has been written from the ROM writer 7, and attach the ROM in which the unique information 1 is written to the corresponding electronic computer 2 (step A2). To do. The dedicated program 8 writes unique information having a different value to the ROM 6 each time another ROM 6 is attached to the ROM writer 7 after writing the unique information to the ROM 6.

  In the conventional method for writing unique information as described above, it is necessary to create and save the dedicated program 8 in the ROM writer 7 before writing the unique information to the ROM 6. It is also necessary to check that the unique information is allocated without error. In addition, in the method described above, when the ROM 6 is written to the ROM 6 using the ROM writer 7 and the ROM 6 is found to be defective, the unique information 1 to be uniquely registered is defective. As a result, there is a problem that the issuing efficiency of the unique information is deteriorated.

  Moreover, generally, there exists a request | requirement that a user wants to display so that the specific information provided can be visually observed. In order to satisfy such a requirement, there is a method in which the unique information written in the ROM 6 is attached to an electronic device such as the ROM 6 or the electronic computer 2 so as to be visible. In consideration of the production management of the electronic computer 2, there are two methods for executing the display as described above.

  FIG. 10 is a flowchart for explaining a first method for attaching the unique information written in the ROM to an electronic device such as a ROM or an electronic computer so as to be visible. In the first method shown in FIG. 10, the electronic computer equipped with the ROM 6 in which the unique information is written is started (step A3), the unique information in the ROM 6 is read by the electronic computer 2, and the visual information including the read unique information is visible. A simple label is created (step A4), and then the created label is attached to the ROM 6 or the electronic computer 2 (step A5).

  However, the first method described with reference to FIG. 10 has to start the electronic computer 2 in order to obtain the unique information in the ROM 6, which takes a lot of time and is unrealistic when considering mass production. It is a simple method.

  FIG. 11 is a flowchart for explaining a second method for attaching the unique information written in the ROM to an electronic device such as a ROM or an electronic computer so as to be visible. In the second method shown in FIG. 11, the unique information is written into the ROM 6 and, at the same time, a visible label including the written unique information is created (step A8), and the physical relationship between the created label and the ROM into which the unique information is written is created. To manage the general association (step A7), and to attach the components including the ROM 6 to the base during the manufacture of the electronic computer as an electronic device (installation component installation, insertion component installation, heat sink installation, etc.) (Step A6), finds a timing at which a label having visually unique information can be attached to the ROM or the information processing device, and attaches the label to the ROM or the information processing device (Step A5). It is.

  However, in the second method described with reference to FIG. 11, while managing the association between the ROM and the label (step A7), the machine assembly operation such as soldering is performed (step A6), and the label is not displayed. You have to wait for the opportunity to stick, and if the number of ROMs and labels to be managed is small, it will not be a problem, but management becomes difficult and complicated when considering mass production of electronic devices such as electronic computers. Cause problems.

  FIG. 12 is a diagram for explaining a second method for writing unique information (in the example described, a MAC address is used as unique information) according to the prior art, and FIG. 13 is a diagram illustrating the implementation of the method shown in FIG. It is a slow chart explaining the work procedure to do. The second method described here is a method in which a ROM 6 in which unique information is not written is attached to the electronic computer 2 and then unique unique information (MAC address A) 1 to be registered in the ROM 6 is written from the ROM writer 7. .

  That is, in the method shown in FIGS. 12 and 13, the ROM 6 in which no specific information is written is first installed in the electronic computer (step A9), and then, as shown in FIG. A ROM writer 7 storing a dedicated program 8 similar to the above is prepared, and this ROM writer 7 is connected to a dedicated input / output device 10 which is a cable adapted to the communication method and the dedicated input / output device 10 in the computer 2. The specific information (MAC address A) 1 is written from the ROM writer 7 to the ROM 6 by using the dedicated circuit 12 for writing to the ROM 6 by connecting to the electronic computer 2 using the dedicated connector 11 to be connected (step A13). ).

  However, the method described with reference to FIGS. 12 and 13 has a problem that a dedicated input / output device 10 for connecting the ROM writer 7 and the electronic computer 2 is required, which is expensive. In addition, this method requires that a dedicated connector 11 for writing to the ROM 6 be attached on the electronic computer 2 and a dedicated circuit 12 for writing to the ROM 6 needs to be added to the electronic computer 2. The place where the connector 11 is attached and the place where the dedicated circuit 12 for writing to the ROM 6 is attached must be secured on the electronic computer 2, and there is a possibility that the entire circuit design needs to be reviewed. There are also problems.

  In addition, the method described with reference to FIGS. 12 and 13 described above requires a dedicated input / output device 10 for each model of the electronic computer 2 from the viewpoint of design and development of different models. When developing the computer 2, it is necessary to manufacture the input / output device 10 for each model and prepare the dedicated connector 11, which causes a problem that the cost is further increased.

As a conventional technique related to the present invention, for example, a technique described in Non-Patent Document 1 or the like is known.

  As described above, the first prior art related to the writing method of unique information for giving unique unique information to an electronic device is that the unique information to be registered is not stored in the ROM when there is a defective product in the ROM. There is a problem that the number of non-defective products is wasted, and the second prior art requires a dedicated input / output device for connecting the ROM writer and the electronic computer, which is expensive. And a place for mounting a dedicated connector for writing to ROM and a dedicated circuit on the electronic computer must be secured on the electronic computer, and the entire circuit design may need to be reviewed. Has the problem.

  Further, in each of the above-described prior arts, in either case, the electronic computer has to be started in order to obtain unique information in the ROM, or the ROM and the electronic computer are physically associated with each other and managed. It has the problem of having to.

  The object of the present invention is to solve the above-mentioned problems of the prior art and to avoid registering unique unique information to be registered by the number of defective products of ROM without using a dedicated interface. It is an object of the present invention to provide a writing method and writing system for unique information that allows a device to have unique unique information.

  According to the present invention, the object is to provide a server having unique unique information to be registered in each electronic device in a method for writing unique unique information given to the electronic device to identify the device, and each electronic device. A ROM writer for writing predetermined specific information in a ROM for holding unique unique information to be registered in the device, and the server is equipped with a ROM in which the predetermined specific information is written When an electronic device is connected to the server, it is achieved by rewriting specific information in the ROM mounted on the connected electronic device to unique unique information to be registered in the electronic device. .

  In addition, in the method for writing unique unique information given to an electronic device to identify the device, the purpose is to register a server having unique unique information to be registered in each electronic device and each electronic device. A ROM writer that writes predetermined specific information in a ROM that holds unique unique information to be provided, and the same number of general-purpose machines as the electronic devices interconnecting the server and a plurality of the electronic devices, The server is mounted on each of the plurality of connected electronic devices when an electronic device on which a ROM in which the predetermined specific information is written is connected to the server via the general-purpose machine. This is accomplished by rewriting the specific information in the ROM to unique unique information to be registered in the electronic device.

  According to the present invention, without using a dedicated interface, it is possible to give unique unique information to an electronic device so that unique unique information to be registered is not wasted by the number of defective products in the ROM. it can.

  Hereinafter, embodiments of a writing method and writing system for specific information according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a system configuration for carrying out a unique information writing method according to the first embodiment of the present invention, and FIG. 2 is a processing operation for writing unique information according to the first embodiment of the present invention. FIG. 3 is a flowchart for explaining processing for creating and pasting a label from unique information written in a ROM according to the first embodiment of the present invention.

  The system for implementing the unique information writing method according to the first embodiment of the present invention shown in FIG. 1 includes a server 3 having unique unique information to be registered in the ROM 6 mounted on the electronic computer 2, and the electronic computer 2. In addition to checking the unique information registered in the ROM 6 mounted on the network, a shipment inspection terminal 23 having a shipment inspection program 24 for checking the shipment of the produced electronic computer 2 is connected via the network communication line 14 to the network 15. In addition, the computer 2 mounted with the ROM 6 in which specific information is written according to the present invention can be connected to the network 15. In the embodiment of the present invention, a ROM writer 7 having a general-purpose program 16 for writing specific information, which is not unique unique information to be registered in the ROM 6, is prepared.

  In the above, when the ROM writer 7 is mounted on the ROM writer 7 and the data writing is instructed, the general-purpose program 16 receives the specific data 21 that appears as the MAC address from other devices connected via the network. Write to ROM6. As the data 21 in the ROM 6 written by the ROM writer 7, the same data may be always written when the ROM 6 is mounted on the ROM writer 7.

  The server 3 has a MAC address A as unique unique information 1 to be registered in the ROM 6 and a MAC address B22 as unique information for recognizing the server 3 from other devices. The shipping inspection terminal 23 also checks the unique information 1 for checking whether the unique information 1 for uniquely identifying the electronic computer 2 in the ROM 6 mounted on the electronic computer 2 is correctly written in the ROM 6. As a specific information for having the MAC address A and recognizing the self-inspection terminal 23 from another device, the MAC address C25 and a shipping inspection program 24 for inspecting a product electronic computer are provided. is doing.

  In the first embodiment of the present invention, the electronic computer 2 on which the ROM 6 in which specific data 21 that appears to be a MAC address from another device is written by the general-purpose program 16 of the ROM writer 7 is mounted on the network communication connector 13, the network When connected to the network 15 via the communication line 14, specific data 21 that appears as a MAC address from other devices in the ROM 6 is transferred to the electronic computer by the writing means 20 in the ROM 6 in accordance with the processing described later with reference to FIG. 2 is rewritten to the unique information A26 for uniquely identifying 2.

  Next, with reference to the flow shown in FIG. 2, a processing operation for executing writing of unique information according to the first embodiment of the present invention will be described.

(1) First, using the ROM writer 7, the specific data 21 that looks like the MAC address from other devices connected via the network is written in the ROM 6, and the ROM 6 in which the specific data 21 is written is installed in the electronic computer 2. (Steps S1, S2).

(2) Next, the computer 2 having the ROM 6 in which the specific data 21 is written is connected to the network 15, and the network 15 is constructed using the network communication line 14 between the server 3 and the shipping inspection terminal 23. To do. At this time, the specific data 21 possessed by the electronic computer 2 has specific data that can be seen as a MAC address from other devices on the network 15, and the server 3 and the shipping inspection terminal 23 uniquely identify themselves. The unique information 22 (MAC address B) and the unique information 25 (MAC address C) are set to different values, so that they can communicate with each other via the network 15. That is, for example, the connection request information from any one of the computer 2, the server 3, and the shipping inspection terminal 23 is sent to the other two devices, and then the device that has received the connection request information. The network 15 is constructed by sending connection permission information to the device that sent the connection request information, and finally sending connection permission information from the device that received the connection permission information to the other two devices. (Step S3).

(3) Writing the unique information to the ROM 6 mounted on the computer 2 connected to the network 15 by operating the shipping inspection terminal 23 using the network 15 constructed by the method described above. Processing is started (step S4).

(4) When the writing process of the unique information is started, first, the shipping inspection terminal 23 sends a unique information transmission request for instructing the server 3 to transmit the unique information to the electronic computer 2. The server 3 that has received the message sends the MAC address A as the unique unique information 1 to be registered in the ROM 6 to the electronic computer 2 as the unique information A26 (steps S5 and S6).

(5) The computer 2 receives the unique information from the server 3 and writes the received unique information in the ROM 6. In this writing, the unique data 1 to be registered in the ROM 6 transmitted from the server 3 is the specific data 21 that appears to the MAC address from other devices connected via the network written in the ROM 6 by the ROM writer 7. Is rewritten to the MAC address A (unique information A26) (step S7).

(6) Thereafter, the shipping inspection terminal 23 operates the electronic computer 2 from the shipping inspection program 24 to perform the shipping inspection of the electronic computer 2 (step S8).

  Through the above-described processing, the fixed value 21 registered in the ROM 6 mounted on the electronic computer 2 is rewritten to the unique information A26. Each time the electronic computer 2 is changed to another electronic computer and connected to the network, the information stored in the ROM mounted on the electronic computer 2 is rewritten to unique information having a different value.

  Next, with reference to FIG. 3, the process of creating and pasting the label from the unique information written in the ROM according to the first embodiment of the present invention will be described as can be seen from the description in FIGS. Since the server 3 transmits the MAC address A as the unique unique information 1 to be registered in the ROM 6 to the electronic computer 2 as the unique information A26, a label is assigned to the server 3 from the unique information transmitted from the server 3. What is necessary is just to make it produce (step S9) and affix the produced label on ROM6 or the electronic computer 2 (step S10).

  According to the above-described method according to the first embodiment of the present invention, the type of information written from the ROM writer 7 to the ROM 6 can be made one type of information in the initial state, so that unique information is uniquely output to the ROM writer 7. Therefore, it is possible to eliminate the need to create and save the dedicated program 8 to be stored. Also, as described with reference to FIG. 3, since unique information to be uniquely registered can be read from the server 3 and a label can be created and pasted, it becomes easy to associate the electronic computer 2 with the label 6, In addition, it is not necessary to start up the electronic computer 2.

  Furthermore, according to the first embodiment of the present invention, since the method of writing data from the network to the ROM 6 is adopted, the input / output device 10 connecting the ROM writer 7 and the electronic computer 2 can be eliminated. The materials and man-hours required for manufacturing the input / output device 10 are not required, and the cost required for them is also unnecessary. Further, according to the first embodiment of the present invention, since it is not necessary to add the dedicated connector 11 and the dedicated circuit 12, it is possible to eliminate the need to review the design required for them.

  FIG. 4 is a block diagram showing a system configuration for carrying out the unique information writing method according to the second embodiment of the present invention. This method according to the second embodiment of the present invention is an extension of the method according to the first embodiment of the present invention described above for mass production.

  The system shown in FIG. 4 is similar to the one described with reference to FIG. 1, the server 3 having unique unique information to be registered in the ROM 6 installed in the electronic computer 2, and the unique information registered in the ROM 6 installed in the electronic computer 2. And a shipment inspection terminal 23 having a shipment inspection program 24 for performing a shipment check of the produced electronic computer 2 is connected to the network 15 via the network communication line 14, and according to the present invention. A plurality of systems configured to be able to connect to the network 15 the electronic computer 2 in which the ROM 6 in which specific information visible to the MAC address from other devices on the network is written are configured to operate in parallel. It is what I did. Also in the second embodiment of the present invention, a ROM writer having a general-purpose program 16 for writing specific information, which is not unique unique information to be registered in the ROM 6, similar to that described in the first embodiment. 7 is prepared.

  As described above, by operating the shipping inspection terminal 23 of each of the plurality of configured systems, the unique information 1 to be uniquely registered is transmitted from the server 3 on the same network as the operated shipping inspection terminal 23 on the network. The unique information 1 can be written to the ROM 6 mounted on the electronic computer 2 by using the writing means 20 to the ROM 6 from the network communication connector 13 of the electronic computer 2.

  By the method according to the second embodiment of the present invention as described above, the server 3 having the unique information (MAC address A) 1 to be uniquely registered for the plurality of computers 2 is uniquely registered by network communication. The unique information 1 to be written can be written simultaneously. Note that the unique information 1 to be uniquely registered for the computer 2 included in each of the plurality of servers 3 is distributed from a master server (not shown) connected to each server 3 via a communication line (not shown). It is possible.

  In the second embodiment of the present invention described above, when a large number of computers are produced and specific information is assigned to the ROM mounted on each computer, only the number of computers to be processed at the same time. A server has to be prepared, which requires a lot of space and a lot of money. However, in order to reduce the number of servers, if one server and a plurality of electronic computers are connected to construct a network, specific information that is not unique information is stored in a ROM mounted on the plurality of electronic computers. Since (same information in all electronic computers) is written, it becomes impossible to construct a network.

  FIG. 5 is a diagram for explaining the system configuration and malfunctions when writing unique information to the ROM on the electronic computer 2 by one server 3 and a plurality of electronic computers 2.

  Now, assume that a network 17 is to be constructed using one server 3, a plurality of electronic computers 2, the same number of shipping inspection terminals 23 (not shown) as the number of electronic computers 2, and network communication lines 14. . In this case, the unique information 21, 22, and 25 that are present in all the devices of the plurality of computers 2, the server 3, and the shipping inspection terminal 23 and that can uniquely identify these devices are all different on the same network. The network 17 can be constructed only when

  However, according to the method of the present invention, as shown in FIG. 1, each of the ROMs installed in a plurality of electronic computers has specific information (all electronic data) that appears as a MAC address from other devices that are not unique information. Since the same information is written in the computer), the same unique information exists on the same network, making it impossible to send and receive connection request and connection permission information, and to build a network. Will not be able to.

  FIG. 6 is a block diagram showing a system configuration for carrying out a unique information writing method according to the third embodiment of the present invention, and FIG. 7 is a processing operation for executing writing of unique information according to the third embodiment of the present invention. It is a flowchart explaining these. In the method according to the third embodiment of the present invention, the number of servers 3 having unique information 1 to be uniquely registered is reduced, and the unique information is written in each of the ROMs mounted on the plurality of electronic computers. It is something that can be done.

  The system shown in FIG. 6 has a server 3 having unique unique information to be registered in the ROM 6 installed in the electronic computer 2 and the unique information registered in the ROM 6 installed in the electronic computer 2, similar to the system described with reference to FIG. And a plurality of general-purpose machines A51 to X53 serving as a bridge having a shipment inspection program 24 for checking the shipment of the produced electronic computer 2 are connected to the network 18 via the network communication line 14. A computer 2 equipped with a ROM 6 in which specific information is written is connected via a network 19 to one of the general-purpose machines A51 to X53 serving as a bridge, as described with reference to FIG. Yes.

  That is, the system shown in FIG. 6 is provided with general-purpose machines A51 to X53 that serve as bridges between the server 3 and the computer 2, and the general-purpose machines A51 to X53 that serve as bridges with the server 3 include them. Specific information 22 (MAC address B) and 54 (MAC address C) to 56 (MAC address X) that can uniquely identify the devices are all assigned to be different from each other. The general-purpose machines A <b> 51 to X <b> 53 can communicate with each other via the network 18. Since the network 18 and the network 19 are separated by the general-purpose machines A51 to X53 serving as bridges, the general-purpose machine serving as a bridge even if the same specific information is written in the ROM 6 of the electronic computer 2 Each of A <b> 51 to X <b> 53 can communicate with each electronic computer 2 via the network 19.

  Next, with reference to a flow shown in FIG. 7, a processing operation for executing writing of unique information according to the third embodiment of the present invention will be described.

(1) First, the system environment described with reference to FIG. 6 is prepared. First, by using the ROM writer 7 in the method described in advance with reference to FIG. 1, specific data 21 that appears to be a MAC address from another device connected via the network is written in the ROM 6, and the specific data 21 is stored in the ROM 6. The written ROM 6 is mounted on the electronic computer 2 (steps S11 and S12).

(2) Next, general-purpose machines A51 to X53 that serve as the same number of bridges as the number of servers 3 and electronic computers 2 are installed, and the server 3 and general-purpose machines A51 to X53 that serve as all bridges are connected to the network communication line 14. The network 18 is constructed by connecting them. At the same time, the computer 19 having the ROM 6 in which the specific data 21 is written is connected to the general-purpose machines A51 to X53 serving as a bridge using the network communication line 14 to construct the network 19 (step S13).

(3) After the processing described above is performed and the environment is prepared, next, the general-purpose machines A51 to X53 serving as bridges are operated, whereby the ROM 6 mounted on the electronic computer 2 connected to the network 19 is operated. The unique information writing process is started (step S14).

(4) When the unique information writing process is started, first, the general-purpose machines A51 to X53 serving as bridges send a unique information transmission request instructing the server 3 to transmit unique information. The server 3 that has received the MAC address A as the unique unique information 1 to be registered in the ROM 6 is sent as the unique information A26 to the general-purpose machines A51 to X53 serving as a bridge (steps S15 and S16).

(5) The general-purpose machines A51 to X53 serving as the bridge send the received unique information to the electronic computer 2, and the electronic computer 2 receives the unique information from the general-purpose machines A51 to X53 serving as the bridge and stores the specific information in the ROM 6. Write information. In this writing, the unique data 1 to be registered in the ROM 6 transmitted from the server 3 is the specific data 21 that appears to the MAC address from other devices connected via the network written in the ROM 6 by the ROM writer 7. The MAC address A (unique information A26) is rewritten (steps S17 and S18).

(6) Thereafter, the general-purpose machines A51 to X53 serving as the bridge operate the electronic computer 2 from the shipping inspection program 24 and perform the shipping inspection of the electronic computer 2 (step S19).

  Through the above-described processing, the unique information 1 including the MAC address to be uniquely registered can be written in the ROM 6 while maintaining the uniqueness while reducing the number of servers 3 as compared with the number of computers 2.

  Each process in the above-described embodiment of the present invention is configured by a program and can be executed by a CPU included in the present invention. These programs are stored in a recording medium such as an FD, CDROM, or DVD. It can be provided and can be provided by digital information via a network.

  According to each of the embodiments of the present invention described above, initial state information (specific data that appears as a MAC address from other devices) is written from the ROM writer 7 to the ROM 6, and the ROM 6 that has been written is attached to the computer 2. Thereafter, the unique information 1 to be uniquely registered can be written in the ROM 6 via the network.

  Further, according to one embodiment of the present invention, the number of servers 3 having unique information 1 to be uniquely registered is reduced, the number of servers to be managed is reduced, and a new input / output device 10 is provided. The purpose of installing the ROM 6 having the unique information 1 to be uniquely registered in the unique electronic computer 2 without the need to add the dedicated connector 11 and the dedicated circuit 12 is also the unique characteristic to be uniquely registered. This can be realized while minimizing the number of servers 3 having information 1.

  According to each embodiment of the present invention described above, a general-purpose machine that becomes a bridge without requiring a person to directly operate the server 3 having the unique information 1 to be registered by direct command input or the like. It is possible to carry out the purpose by operating.
