Description

  The present invention relates to an RFID system.

In order to lay electrical cables in plants, railways, and buildings, work specifications are created from design circuit drawings, and workers perform laying, wiring, testing, and removal work while referring to this. The work is done as follows. First, the cable is routed in the plant while referring to the work place indicating the starting point and the arriving point of the cable. FIG. 2 is sequence information printed on paper and shows a partial sequence of the entire plant. FIG. 3 shows information supplementing FIG. 2 and shows a connection diagram between the terminal block printed on paper and the cable core. The connection / disconnection work is performed with reference to FIG. After the connection / disconnection work, a sequence test is performed with reference to FIG.

If reliability is emphasized, it is necessary to eliminate human error from such cable laying work, but even if multiple checks are made, the cost will be high, and it will depend on the height of the worker's consciousness, resulting in complete human error It does not lead to exclusion.

Therefore, Japanese Patent Application Laid-Open No. 2003-114247 discloses a technique for writing wiring information on an RFID and attaching it to a cable. Japanese Patent Application Laid-Open No. 2004-349184 discloses a technique for issuing a warning for inappropriate wiring by attaching an RFID to a cable and providing a reader function on the terminal block side. In the former, the type to be written is fragile, and there is a complexity that must be rewritten every time the situation changes. Moreover, the latter has the subject that it will become expensive when a reader function is provided in a terminal block.

  The present invention relates to a system that can eliminate human error and can work efficiently.

  Embodiments will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram of an embodiment of the present invention. Specific examples of information held in the data storage device 3 are shown in FIGS. Examples of the operation of the PC 2 are shown in FIGS.

A cable 8 in FIG. 1 is a cable for connecting terminals to each other like a cable C3, and one end thereof is connected to a specific terminal of the control panel 5. The reader 1 is an RFID reader, and outputs the identification ID (tag ID) to the signal line 101 when the identification ID stored in the RFID is read. The reading operation is repeated every predetermined time, or the reading is performed at the timing when the trigger is applied from the PC via the signal line 101. The PC 2 is a PC or PDA, a small microcomputer, and the like, and generally includes a CPU, a memory, and a storage device. In each work mode, the PC 2 receives the identification ID (tag ID) read by the reader 1 via the signal line 101 and receives this identification ID.
(Tag ID), circuit information / RFID information / work procedure information of the data storage device 3, and input from the user such as mode selection and target selection are combined to support the work. The data storage device 3 may be on a storage device included in the PC 2 or may be on a storage device not included in the PC 2 such as on the Internet. In the latter case, the PC 2 needs to have a communication function.
The circuit information is circuit information using the terminal ID and the cable ID, and includes connection information of the terminal ID and the cable ID. By referring to this information, it is information that can obtain the cable ID to be connected from the terminal ID, and conversely the terminal ID to be connected from the cable ID. The cable ID will be described below as specifying to which end of the cable, but the cable ID is not an ID specifying to which end of the cable, but as an ID as a cable having both ends (starting point) (End, landing end) may be managed separately. In that case, when the cable ID and which end are designated, the terminal ID to be connected can be specified. In addition to terminals and cables, RFID can be attached in this embodiment to cables, terminals, control panels, control panel terminals, cable trays, cable tray branch points, controlled devices, and other items to be checked during sequence tests. The circuit information must be described by the object ID indicating these or by the ID corresponding to the object ID.
The RFID information is a correspondence between the identification ID stored in the RFID and the object ID indicating the object to which the RFID is attached. The cable ID indicating one end of the cable 8 and the identification ID stored in the RFID 7_1 attached near the cable terminal are associated with each other and registered in the RFID information. In this embodiment, RFIDs are attached to cables, terminals, control panels, control panel terminals, cable trays, cable tray branch points, controlled devices, and other important points to be checked during sequence tests. The same applies to other cases. Referring to this information, the identification ID stored in the RFID attached to the entity represented by these is obtained from the cable ID or terminal ID, and conversely, the cable ID or terminal ID is obtained from the identification ID stored in the RFID. be able to.
The work procedure information is information indicating a work procedure, a list of work contents of a worker on a certain day, and an identification stored in the ID indicating the target to which the RFID is attached or the RFID attached to the procedure in the individual work. It is represented by ID. An example of a list of work contents of a worker on a certain day will be described later with reference to FIG. As an example of individual work, if the work is to confirm the connection between the terminal and the cable, the user is prompted to confirm the terminals included in the terminal block in order, and the individual confirmation results are shown to the worker. Alternatively, the confirmation order is indicated by the cable ID or the identification ID stored in the RFID, and stored as procedure information. As a method for indicating this work procedure to the user, in the display as shown in FIG. 3, the terminal or cable to be checked next is highlighted by changing the color or blinking, or indicated by the LED described later, or by the terminal ID or The cable ID may be displayed as a text string. Further, another example of individual work will be described later with reference to FIGS.
When it is necessary to indicate the terminal of the control panel 5 as part of the work support, the terminal ID is output to the signal line 102. When the LED controller 4 receives the designation of the terminal ID from the signal line 102, the LED controller 4 causes the LED 6 indicating the corresponding terminal to emit light. When the terminal of the control panel 5 is not shown, the signal destination 102, the LED controller 4, the LED 6, and the work procedure information may not be included. The RFID 7 is a passive type RFID and will be described below as having no writing function, but an active type or one having a writing function can also be used. RFID7 is affixed or embedded in advance in cables, cable core terminals, control panels, control panel terminals, cable trays, cable tray branch points, controlled devices, and other important points to be checked during sequence tests. Leave in or leave.

  The data storage device 3 holds circuit information, RFID information, and work procedure information, and also holds work records. The information may be obtained sequentially by using a memory or a disk inside the PC 2 or by placing this information on a server machine and allowing the PC 2 to have a communication function with the PC 2. Even when using the memory or disk inside the PC 2, data is stored in the server machine, data related to necessary work is downloaded from the server before work, and after the work is uploaded, information is uploaded by uploading work records. It can be shared and the progress of work can be easily understood.

As an example of operation according to the configuration of FIG. The operator performs the work after setting each mode by pressing a button from the main menu in FIG.
[1] Connection mode:
(1) The identification ID stored in the RFID of the cable 8 is read by the reader / writer 1.
(2) The reader / writer 1 sends an identification ID (tag ID) to the PC.
(3) After the PC 2 obtains the cable ID associated with the identification ID (tag ID) with reference to the RFID information stored in the data storage device 3, the terminal to which the cable ID is to be connected with reference to the circuit information An ID is obtained and sent to the LED controller 4.
[2] (4) The LED controller obtains the LED number indicating the terminal ID, and lights the corresponding LED of the LED 6.
(5) The operator receives an instruction from the illuminated LED and connects the cable to the terminal.
As described above, according to the connection determined by the circuit information, when the RFID attached to the cable is read, the LED indicating the terminal to be connected shines and can be shown to the operator. For example, if the right end of the cable 8 is to be connected second from the upper left side of the control panel 5, when the RFID 7_1 is read by the reader 1, the second LED 6 from the upper left side of the control panel 5 shines.
This method may be displayed on the PC screen without performing (4) and (5). For example, the connection diagram is displayed in the same format as the terminal block as shown in FIG. 3, and the corresponding terminal is highlighted by changing the color or blinking. In that case, the signal destination 102, LED controller 4, LED 6, and work procedure information may not be included in the configuration shown in FIG.
[2] Confirmation mode:
(1) Read the RFID tag of the cable 8 with the reader / writer 1.
(2) Read the RFID tag 7_ of the control panel 5 with the reader / writer 1.
(3) The PC 2 obtains the cable ID associated with the cable identification ID (tag ID) by referring to the RFID information stored in the data storage device 3, and then the cable ID is connected by referring to the circuit information. Get the power terminal ID. Further, the terminal ID2 associated with the RFI tag 7_ of the RFID information control panel 5 is obtained.
(4) If the terminal ID and the terminal ID 2 match, the PC 2 sends a signal to the LED controller 4 so that the terminal ID is illuminated as having been correctly connected. If they do not match, a signal is sent to the LED controller 4 so that the terminal ID or the terminal ID2 blinks and lights as not being a correct connection. Whether or not they match may be converted to a cable ID and collated.
(5) The LED shines or flashes.
In this method, a match / mismatch may be indicated by a buzzer or the like instead of (5). In that case, the signal destination 102, LED controller 4, LED 6, and work procedure information may not be included in the configuration shown in FIG.
[2 '] Alternative confirmation mode:
(1) The PC 2 obtains a confirmation procedure for each terminal of the control panel 5 to be connected from the work procedure information stored in the data storage device 3. This test procedure (confirmation procedure) is to confirm from the top to the end in the case of a single vertical terminal block row, but other orders may be used. The PC 2 sends a signal to the LED controller 4 so that the LED of the terminal ID to be confirmed blinks.
(2) Read the RFID tag of the cable 8 connected to the terminal indicated by LED blinking by the reader / writer 1 (3) The PC 2 refers to the RFID information and associates the cable ID with the cable identification ID (tag ID) After obtaining the terminal ID2, the terminal ID2 to which the cable ID is to be connected is obtained by referring to the circuit information.
(4) If the terminal ID to be confirmed matches the terminal ID2 to which the cable ID is to be connected, a signal is sent to the LED controller 4 so that the terminal ID is illuminated as having been correctly connected. If they do not match, a signal is sent to the LED controller 4 so that the terminal ID or the terminal ID2 blinks and lights as not being a correct connection.
(5) The corresponding LED 6 shines or blinks.
[3] Disconnection mode: Performed in the same way as [2] (1)-(5), but if it does not match in (5), it will be possible to take notes, such as displaying a screen where you can enter notes. good.
[4] Test mode: The LED lights according to the test procedure included in the work procedure information stored in the data storage device 3. Details will be described later with reference to FIG.
Here, the method of attaching the RFID to the core of the cable has been described, but it may be attached to the cable body instead of the core. In this case, since the terminal block corresponding to the cable ID is displayed on the PC 2 and the core wires cannot be specified, it is preferable to highlight all the terminals related to all the core wires or to illuminate the LEDs.

  Specific examples of information held in the data storage device 3 of FIG. 1 are shown in FIGS.

FIG. 2 is an example of circuit information of the data storage device 3 and is called a sequence diagram. Circuits consist of components such as cables, cable cores, control panels, control panel terminals, cable trays, cable tray branch points, controlled devices, and other important points to be checked during sequence tests. Each component is shown with a unique ID. The sequence test is confirmed in order from this left side. Although shown here as a diagram, the diagram is stored in the data storage device 3 as a database having information that can be automatically generated.

FIG. 3 is an example of circuit information of the data storage device 3 and is called a terminal block wiring diagram. Prior to the sequence test, it is necessary to configure the circuit by connecting the cable to the terminal of the control panel or equipment. Although shown here as a diagram, the diagram is stored in the data storage device 3 as a database having information that can be automatically generated. As an example, FIG.
This corresponds to information in the first to fourth columns from the left. This is correspondence information (connection specifications) between control panel terminals and cable core terminals. “X23” indicating the row of the control panel in FIG. 3 is the row number of the first row in FIG. 4, and “1” to “21” indicating the terminals of the control panel in FIG. 3 are the second row (of the control panel) in FIG. The position of the line indicating the correspondence between the terminal number and the core wire in FIG. 3 holds information indicating the cable name such as the fourth row core wire number and “C000100” in FIG.

FIG. 4 is an example of RFID information of the data storage device 3. Although information that can be automatically generated as shown in FIG. 3 is also provided, the RFID information corresponds to information in columns 3 to 5 from the left in FIG. In the third row and the fourth row, information on which RFID of the fifth row is attached to which core of which cable is held. Similarly to cables, cables, control panels, control panel terminals, cable trays, cable tray branch points, controlled devices, and other circuits that show this for key points to be checked during sequence tests Information that associates the ID or unique name used in the information with the RFID value that is pasted, embedded, or placed on the real object is held.

  FIG. 5 is an example of work procedure information in the data storage device 3. This is a list of tasks that an individual should perform as a result of allocating all tasks to workers. Here, in the fixed length area, the personal name, the work start date / time, the work end date / time or data indicating work incomplete, and the connection work, test work, and removal work are shown as a work list. Also, the data indicating the end of the work list is at the end. Detailed specifications of each work are specified in another area and will be described later with reference to FIG.

  An operation example of the PC 2 in FIG. 1 will be described with reference to FIGS.

2-1 in FIG. 6 is a system login screen. Select from the list of operator names registered in advance and press the OK button. Alternatively, the method may be such that the RFID assigned to the worker is read and logged in. In this case, as RFID information to be held in the data storage device 3, information assigned to the worker and the RFID needs to be prepared in advance. There is. When logged in, the process moves to the menu list screen (FIG. 62-2). All may be displayed, but if only the next work menu is displayed according to the procedure information, the operator can easily operate. When the operator designates a menu, each operation mode described with reference to FIG. 1 is set.

  Hereinafter, the connection menu will be described with reference to FIGS. When the operator presses the connection menu from the main menu display of FIG. 6 2-2, the system displays a work list indicating which control panel or device is connected as shown in FIG. The operator can easily select the work object by clicking on the work object, or by attaching the RFID to the control panel or device in advance and reading it with a reader. When the worker selects a work target, the system shifts to a connection mode and displays a connection mode screen as shown in FIG. 18 2-4. This screen is easy to work if displayed in the same manner as the diagram called the terminal block wiring diagram described in FIG. This figure is automatically generated from the circuit information stored in the data storage device 3 and displayed. “ABC10” is the name of the control panel selected by the operator on the screen of FIG. 6 2-3, and this figure shows the control panel information. Since the control panel normally has two rows on the left and right, it is displayed here in two rows, but it may be displayed on only one side. “A01” to “B20” are names of terminals, and the numerical values arranged on both sides thereof are terminal identification numbers. “C1” to “C9” are names of cables, and their descriptions are displayed below the names. C1 has three cores, and one line is displayed from the shield. When a color is attached to each core line, it may be easy for the operator to understand intuitively if the color is displayed. If the line segment indicating the core wire is connected to the terminal identification number as in C1, it indicates that it is currently connected, and if it is not connected as in C2, it indicates that it is not connected during disconnection. When the RFID of the core wire is read, it is easy to understand if the core wire is blink-displayed or the identification name or identification number of the corresponding terminal is highlighted (C7). In addition, the status of whether or not connected may be displayed near the cable or terminal. During connection, there are workers who connect the terminals in the order of the terminal numbers, so to find the core wire to connect to the terminal, you can read the RFID one after another so that you can find the core wire. It is necessary to cancel the RFID.

  The confirmation mode will be described below. The confirmation mode confirms whether the cable and terminal are correctly connected. Since the operation is performed for each control panel, a screen similar to FIG. 18 is displayed. First, the terminal identification name or gray color such as gray is displayed and the RFID on the cable side is read in the order of the terminal numbers. Terminals to which no cable is connected and terminals not subject to confirmation read the RFID on the terminal side. When read in this order, if it matches the circuit data, it is confirmed. A finished mark may be displayed so that confirmation / non-confirmation can be understood, and it is necessary to indicate to the operator. If there is a discrepancy with the circuit information, it is displayed so that the operator can know which terminal and cable have the discrepancy. If the operator corrects the mistake and the inconsistency is resolved, it is confirmed and finished, and if the RFID cannot be read, or it is necessary to cope with the inability to connect partly, the agreement cannot be resolved. It is better to record that fact. For example, a “memo” menu button is provided at the lower part of FIG. The memo pad may be text, but it is preferable that a memo is written as a handwriting with a pen or a mouse, or text can be searched by recognizing the handwriting. If the confirmation mode ends without confirmation with a memo, a statement to that effect should remain in the work report.

As described above, the connection mode has been described as an example in which the RFID is attached in advance. However, what is important is to attach the RFID without making a mistake. That is, it is necessary that the RFID information stored in the data storage device 3 is exactly the same as that attached to the real object, and if the RFID is mistakenly attached between the core wires, the work itself is also mistaken. Therefore, the RFID mounting means will be disclosed below with reference to FIG. 7, FIG. 15, and FIG.

First, the first method is to prepare the cable, RFID to be attached to each core on both sides
Prepare each. For example, as shown in FIG. 15, a tag is hung at both ends of the cable, and an RFID is prepared together with an instruction of an attachment core. The RFID may be written in the RFID information shown in FIG. 4 at the stage of creating the bill, or may be written while attaching the RFID on site. To ensure that there are no mistakes, in the screen of FIG. 7 2-5, after the process of (1) designating the cable name and core, (2) reading RFID, (3) writing to RFID information It is better to specify (1) after (2) in reverse order. For example, (2) RFID of core wire
(1) When specifying the cable name, if the cable has an RFID, read this,
For the specification of the core wire, a screen as shown in FIG. 7 2-7 is displayed and the color of the attached core wire is specified. FIG. 16 shows an allocation processing flow. When the “assignment” menu is selected in the main menu of FIG. 6 2-2 in procedure 1, the process moves to the assignment mode. In step 2, the user designates the control panel number Sno, but the RFID indicating the control panel number attached to the control panel in advance.
You may specify by reading. Here, a list of cables may be displayed. Displays information on the core of the selected control panel number or cable number. That is, the control panel number data is read from the back diagram or the like. Steps 5 to 6 are repeated while attaching the RFID until the end of the “assignment” menu. In step 5, the cable name and the core wire are designated from the list in FIG. 7 2-5. The designation of the cable name may be changed by reading the RFID indicating the cable attached to the cable in advance. The specification of the core wire is preferably automatically set in order from the first by default. Next, in step 6, the RFID is read. Next, in step 7, the system program associates the cable name specified in step 5 with the RFID read in step 6 as the RFID information of the core wire, and updates the data as RFID information. When RFIDs have been attached to all the cores, an assignment confirmation mode is entered. This time, the RFIDs are read in the reverse order in step 9, and then the cable name and the core are designated in step 10. If the contents received in steps 9 and 10 match the RFID information received in steps 5 and 6, it is confirmed that the color of the corresponding cable core is changed in the display 2-5 in FIG. Display so that you can see what is confirmed and what is not. After the end of step 8, it is possible to guarantee that the RFID attached to the cable or control panel of this work is consistent with the RFID information, and whether or not the warranty can be issued is determined by whether or not the end of step 8 Good.

FIG. 8 is a screen example of the removal mode. The name of the cable to be removed is displayed, and when the RFID attached to this cable is read, the cable is highlighted and the user can easily understand by voice and display that it can be removed or cannot be removed. Let them know. For this purpose, RFID is provided at various points of the cable as shown in FIGS.
It is necessary to be able to follow the identification name on the circuit information of the cable by reading this. In addition, the identification name on the circuit information may be written in the RFID. FIG. 13 sequentially shows the RFIDs before the cable is cut. The RFID data pasted at the time of cable creation and the pasted RFID data are used for this, or the data read in sequence after pasting is used. After the cable is cut and the cable identification name is defined, the RFID near the both ends is read and associated with the cable identification name as shown in FIG. This
Using the data of FIGS. 12 and 13, it is possible to trace to which cable the read RFID belongs. That is, the RFID information of the cable held in the data storage device 3. If circuit information is retrieved from the cable identification name, detailed information such as the origin and destination of the cable can be obtained.

On the right side of FIG. 8, information on the read RFID tag is displayed. In addition to the removal mode, it is also possible to apply to other work by following the information of the RFID attached.

  The sequence test support will be described with reference to FIGS. 9, 10, 11, and 17.

In the sequence test mode, it is possible to switch between FIGS. 9 and 10 using a tab. FIG. 9 shows a sequence diagram and which part of the test is completed. FIG. 10 shows a procedure list and how far the procedure has been completed. The completed procedure is indicated by a fine character, the procedure from now on is indicated by a bold character, and the next procedure is indicated by a triangle mark. As shown in FIG. 10, an operation of reading the RFID attached (placed) on the object of the procedure is put in, and it is confirmed that the device to be confirmed is not wrong. Further, in the procedure information, information on which part of the sequence diagram of FIG. 9 corresponds to the procedure of FIG. 10 is held, and at each stage of the procedure of FIG. It can be displayed whether it has finished. Do not list the procedures.
If rough procedure items and detailed procedures are shown for each of them, a familiar worker can work while referring to only the rough procedures, and work efficiency can be improved. If the work proceeds according to the procedure, and the RFID read in the middle is also as specified, it is good to determine whether or not a work guarantee can be issued in accordance with the end status of the sequence test.

  The sequence test procedure will be described with reference to FIG.

When the operator selects the “Test” menu from the main menu in step 1, the process moves to the sequence test mode. Although the operator selects the sequence number in the procedure 2, it may be specified by reading an RFID attached to a test object such as a control panel in advance. By adding a function to search the specified RFID and the test work related to the user from the work procedure information of FIG. 5, the distance traveled during the narrowing-down test can be reduced and the work efficiency can be increased. Can do. Sequence data is read in step 3, and FIGS. 9 and 10 are displayed. Repeat step 5 and subsequent steps until the end of the “TEST” menu in step 4. In step 5, the following procedure is displayed as shown in FIG. If the current procedure in step 6 involves reading RFID, the procedure waits until reading RFID in step 7 and determines whether or not it matches the designated RFID. If OK, the current procedure in step 9 is ended. If the current procedure in step 6 does not involve reading RFID, the user presses the work end button or instructs the next work item. End of procedure and step 10
To reflect the progress. If the RFID is different in the procedure 7, the error process of the procedure 8 is executed.

-If the RFID is misread or the operator is prompted to read again, and if it is OK, step 9
Proceed to
・ If it is different even if you read RFID again,
・ If RFID cannot be read,
Ask the worker to enter the status in the explanation area in the error handling.
・ Continue or interrupt the work.

However, when the work is continued in this state, that fact is described in the work guarantee content.

FIG. 17 shows the connection status of the relevant part of each sequence. Cable C1
The terminal represented by the RFID (7_1R_1) of the control panel 1 and the RFID (7_2L) of the control panel 2
_1) is connected to the terminal. For example, in the sequence test 1, C1 and C3 are confirmed. In the sequence test 2, if C1 and C4 are confirmed, if the work end of the sequence test 1 is within a predetermined period, the sequence test 2 The test for C1 can be omitted. For this purpose, the procedure information needs to have a unique ID attached to the partial sequence in the sequence diagram of FIG. 9 and hold information on which of the unique ID tests the procedure of FIG. 10 corresponds to. is there. It is also necessary to store information on when the unique ID test is completed and to refer to this information. As a result, it is possible to check whether there are partial sequences represented by the same unique ID in different sequence diagrams and whether the test has been completed. Thus, if there is a partial sequence that has already been completed in the sequence test 1, when the sequence diagram is displayed with respect to the sequence test 2 as shown in FIG. 9, the live portion can be recorded as such. As shown, the completed part is displayed as finished and the test procedure is skipped.

System operation status of the operator since the system was started (menu button pressed, RFID
Recording the time of reading, etc.), it is possible to confirm how the work has proceeded. Thereby, basic data on what kind of work is troublesome can be collected. Based on this data, the work amount of each work can be estimated from the cable length (in this case, it is necessary to keep the length for each cable ID), the number of terminals, and the number of test procedures. It is possible to appropriately allocate work among persons.

FIG. 19 shows an example of the confirmation mode screen. In order to input the connection status, the RFIDs of the cables connected in order of the terminal numbers of the terminal block are read, and the terminals not connected to the cables are read the RFID attached to the terminals. . RFID for terminal block as another method for inputting connection status
Read two RFIDs of the cable connected to each other. When the user presses the “PRINT” button at the bottom of the screen after inputting the connection status, the user can easily create a report by automatically creating a work report as shown in FIG. Also, save the time when you started in the confirmation mode or the time when you read the RFID of the cable at the first terminal, and the time when you read the RFID of the cable at the last terminal or when you finished the confirmation mode. If you automatically enter the work date and time, you can handle it as proof of work.

In order for the PC 2 to sequentially update data to the data storage device 3 that can be shared with others over the network, both need communication means. Alternatively, the data storage device 3 is stored in the PC 2 before work.
The data may be downloaded from and updated and stored locally in the PC 2 during the work, and the data may be uploaded after the work. In this case, the warranty information needs to be updated at the same time. The guarantee information is the one that “guarantees that the attached RFID matches the RFID information” by the assignment operation described with reference to FIG. 16, or the “test is the RFID information by the sequence test operation in FIG. Or “guaranteed that the connection status has been checked against the drawing using RFID”. In addition, the progress and log need to be uploaded to the data storage device 3 from the local.

As a result, the system of the present invention provides the ID used for circuit information such as design data,
Since the system has correspondence information with the RFID attached to the actual product as data, you can check which part of the circuit information is working by referring to this data from the RFID read by the reader, so you can work without writing to the RFID There is an advantage that can support.

Further, since the system of the present invention has a reader function on the work terminal side, there is an advantage that it is not necessary to provide a reader function for each terminal block and the cost can be reduced.

In addition, since the system of the present invention has correspondence information with the RFID attached to the real thing as data for the ID used in the circuit information such as design data, the sequence information which is the circuit information is included in the part of the sequence diagram. There is an advantage that the sequence test can also be supported by reading the corresponding RFID during work.

In addition, if the LED plate attached to the chassis and the operation in the confirmation mode are used, it can be applied to an indispensable use for navigating the position and confirming whether or not the user has reached the place, such as a muffled game.
