Description

  The present invention relates to a module mounting system and a module mounting method, and in particular, when mounting a module such as a CPU device (Central Processing Unit) used for assembly of a measurement terminal device or the like on a substrate, a mounting error is caused. The present invention relates to a module mounting system and a module mounting method.

  For example, a measurement terminal device used in a monitoring control system is assembled by mounting a CPU device, which is a type of module having a control function, a memory function, etc., on a backboard (substrate). As shown in the front view of FIG. 9, the schematic configuration of the measurement control device 101 is such that each of cages 1 and 102A to cages 4 and 102D provided in a plurality of stages in the vertical direction has a plurality of slots 1 and 103A in the horizontal direction. A configuration in which a plurality of CPU devices 105 are mounted and mounted in corresponding cages 1 to 4 and slots 1 to 16 on a housing-like backboard 104 that is divided by slots 16 and 103X. Has been. As the scale of the monitoring control system or measurement control device increases, the number of CPU devices 105 mounted on the backboard 104 inevitably increases.

  In such a measurement control device, whether or not the CPU device is correctly mounted at a position corresponding to a mounting position that is a predetermined corresponding cage and slot position of the backboard is determined by whether or not all the CPU devices are mounted. It becomes clear only after the measurement control device is operated after the completion. This is because the measurement control device cannot be operated unless all the CPU devices and the backboard are brought into contact and electrically connected. In addition, when a mounting error occurs because the CPU device is not accurately mounted at the mounting position, it adversely affects many CPU devices mounted on the same backboard.

  In addition, in order to set application information corresponding to the mounting position, it is necessary to set SG (System Generation) information (IP address, station number, etc.) of the CPU device corresponding to the mounting position. Since there is no method to set, all the work is done manually by visual confirmation of the mounting position. For this reason, not only the setting efficiency of application information is deteriorated, but also human errors are likely to occur. As described above, as the size of the monitoring control system or measurement control device increases, the number of mounting positions increases (the number of slots increases). Therefore, a mounting error on the back board of the CPU device or an application information setting error occurs. Are likely to occur, and these mistakes can be recognized only when the mounting of the CPU device is completed. In particular, since there are many situations in which mistakes are not allowed when replacing devices in actual operation sites such as measurement control devices, a mechanism for automatically eliminating human errors is desired.

  When implementing functions such as scanning and printing in a copier, a recognition ID (Identification) is provided on the sub-board to prevent mounting errors when mounting the sub-board on the main board having a plurality of slots. There is an idea (Patent Document 1). In addition, in order to prevent a mounting error when mounting a package on a substrate in an information processing apparatus or the like, there is an idea of providing a recognition ID for the package (Patent Document 2 and Patent Document 3).

  However, in any of Patent Document 1 to Patent Document 3, mounting errors are prevented by using IDs provided on modules such as sub-boards or packages to be mounted. This is to detect whether or not a mounting error occurs after the process is completed. Therefore, as described above, it is inevitable that many modules connected to the same substrate are adversely affected.

  When a semiconductor memory (module) that serially communicates information according to the SPD (Serial Presence Detect) standard is mounted on a motherboard (substrate), a plurality of terminals such as a serial clock terminal and a serial data terminal are connected to the connector terminal of the module. In order to prevent a decrease in the utilization efficiency of the module terminals caused by providing the module, the module is provided with an IC tag that wirelessly transmits information related to the module, and the motherboard is provided with a reader that receives a radio signal from the IC tag. A module mounting system configured as described above is considered (Patent Document 4). In this system, the operation of the module is controlled by wirelessly transmitting information about the module to the motherboard.

By the way, although the conventional module mounting system disclosed in Patent Document 4 can achieve the purpose of improving the utilization efficiency of the module terminal by wirelessly transmitting information about the module from the module to the motherboard, the module is mounted on the board. No consideration is given to preventing mounting mistakes that are likely to occur during mounting.
Further, in the module mounting system of Patent Document 4, only the idea of non-contact transmission of information between the module and the motherboard is shown, and application information corresponding to the mounting position at the time of module mounting is manually set. Also, problems that are likely to occur are not considered.

  The present invention has been made in view of the above circumstances, so that it is possible to detect whether or not a mounting error has occurred before mounting a module on a board, and to automatically set application information. It is an object to provide a module mounting system and a module mounting method.

  The configuration of the present invention relates to a module mounting system in which a module having a function of performing a predetermined operation is mounted on a board, and the board has a slot in which the module is to be mounted and is mounted in the slot. Wireless communication means to which unique ID information for identifying a module is provided, the module reading ID information from the wireless communication means in a non-contact state by wireless communication; and the module on the substrate. Before mounting, the ID reading unit of the module reads the ID information from the wireless communication unit of the board in a non-contact state by wireless communication, and based on the reading result, whether the module has a mounting error. And a mounting position determination unit that determines whether or not.

  According to the module mounting system of the present invention, the board is provided with the wireless communication means to which the unique ID information for identifying the module to be mounted is provided, and before the module is mounted on the board, the module ID reading means The ID information is read from the wireless communication means in a non-contact state by wireless communication, and based on the read result, it is determined whether or not the module has a mounting error. The presence or absence can be detected. Further, since the module includes an application unit in which application information for performing a predetermined operation is stored in advance, application settings can be automatically performed.

Embodiment 1

  FIG. 1 is a block diagram showing a schematic configuration before module mounting in the module mounting system according to the first embodiment of the present invention, and FIG. 2 is a block diagram showing a schematic configuration after module mounting in the module mounting system. 3 is a perspective view showing a specific example before module mounting in the module mounting system, FIG. 4 is a perspective view showing a specific example after module mounting in the module mounting system, and FIG. 5 is used in the module mounting system. FIG. 6 is a perspective view showing a specific example of the substrate, and FIG. 6 is a flowchart showing a module mounting method using the module mounting system. In this embodiment, a CPU device is used as a module, and the CPU device is applied to a slot mounting type CPU device in which the CPU device is mounted in a slot on the backboard.

  As shown in FIGS. 1 and 2, the module mounting system 1 of this embodiment includes an IC reader 10, a mounting position determination unit 11, an application setting unit 12, an alarm control unit 13, a mounting information unit 14, an application unit 15, A CPU device (module) 2 having a joint 16 for general connection and a backboard (substrate) 3 on which the CPU device 2 is mounted are provided. When the CPU device 2 is mounted on the backboard 3, for example, a measurement terminal device or the like capable of a predetermined operation is assembled.

  As shown in FIGS. 3 to 5, the backboard 3 is formed in a casing shape in which the cage 4 is divided by a plurality of slots S (S0 to S7) in the lateral direction, and the CPU device 2 is placed in each slot. It is configured to be mountable. Each slot S is provided with a joint 5 that is electrically connected to the joint 16 of the CPU device 2, and each slot S is provided with a bus 6 that is electrically connected to each other. Data is exchanged between the mounted CPU devices 3.

  Further, an IC tag (wireless communication means) 7 capable of transferring information in a non-contact state between the CPU device 3 and the backboard 3 is incorporated in the form of an IC chip on the surface of the backboard 3 facing the CPU device 2. ing. The IC tag 7 has a slot-specific backboard ID 8 assigned in advance for each slot (stored). For example, a backboard ID unique to this slot S0 is assigned to the slot S0, and a backboard ID unique to this slot S1 is assigned to the slot S1, and a unique backboard ID is assigned to all slots and stored. Has been. Therefore, in the first embodiment, eight types of backboard IDs corresponding to the eight slots (S0 to S7) are assigned and stored in the IC tag 7. These backboard IDs 8 play a role of specifying the CPU device 2 mounted in each slot of the backboard 3 as ID information.

  As shown in FIG. 1, the IC reader 10 of the CPU device 2 is a slot corresponding to the CPU device 2 in a non-contact state from the IC tag 7 before the CPU device 2 is mounted in each slot S of the backboard 3. The unique backboard ID is read, and the reading result is transmitted to the mounting position determination unit 11. The mounting position determination unit 11 checks the mounting information stored in the mounting information unit 14 and determines whether or not the read backboard ID is a backboard ID that identifies the CPU device 2, that is, the CPU device 2 is accurate. It is determined whether or not it is mounted at a proper mounting position. For example, if the mounting position of the CPU device 2 is the slot S1, the back information ID unique to the slot S1 is stored in the mounting information unit 14 as information for specifying the CPU device 2. In this case, the mounting position determination unit 11 determines that no mounting error occurs even if the CPU device 2 is mounted in the slot S1.

  Here, when the backboard ID read by the IC reader 10 is a backboard ID that does not specify the CPU device 2, the mounting position determination unit 11 checks the mounting information unit 14 and regards it as a mismatch. When the CPU device 2 is mounted in the slot S1, it is determined that a mounting error occurs, and a warning is generated by the alarm control unit 13. The warning can be made by using an audible means that sounds a buzzer or a visual means that blinks a light.

  When the mounting position determination unit 11 determines that the CPU device 2 does not cause a mounting error as described above, the mounting position determination unit 11 controls the application setting unit 12 and the application unit 15 to automatically set application information. The application unit 15 stores application information for each slot of the backboard 3 in advance. The application information actually indicates an executable file or SG information. That is, the mounting position determination unit 11 searches whether or not application information that matches the backboard ID read by the IC reader 10 is stored in the application unit 15. When application information that matches the backboard ID is retrieved, the mounting position determination unit 11 controls the application setting unit 12 to develop it in the operation area.

  Here, when the application information matching the backboard ID is not searched, the application information is not automatically set. Therefore, the mounting position determination unit 11 uses the alarm control unit 13 to hear a buzzer or the like, Use visual means to flash the light to generate a warning.

  As described above, before the mounting of the CPU device 2 on the backboard 3, it is determined that the mounting position determination result does not constitute a mounting error, and the application information is automatically set. Since no warning is generated by the control unit 13, the CPU device 2 is mounted in the slot of the backboard 3. At this time, if the backboard 3 is in a live line state such as power-on, the CPU device 3 can perform a normal operation based on application information stored in the application unit 15 in advance.

Next, a module mounting method using the module mounting system of the first embodiment will be described with reference to the flowchart of FIG.
First, the CPU device 2 to be mounted is placed in front of the slot S of the backboard 3, and the slot corresponding to the CPU device 2 in a non-contact state from the IC tag 7 of the backboard 3 by the IC reader 10 of the CPU device 2. The unique backboard ID is read (step S1).

  Next, the IC reader 10 transmits the reading result to the mounting position determination unit 11, and the mounting position determination unit 11 collates the mounting information stored in the mounting information unit 14, and the read backboard ID is the CPU. It is determined whether or not the backboard ID identifies the device 2 (step S2). When the backboard ID unique to the slot S1 is stored in the mounting information unit 14 as information for specifying the CPU device 2, the mounting position determination unit 11 is mounted even if the CPU device 2 is mounted in the slot S1. It is determined that no mistake is made, and the flow proceeds to step S3. On the other hand, when the read backboard ID is a backboard ID that does not specify the CPU device 2, the mounting position determination unit 11 determines that a mounting error occurs when the CPU device 2 is mounted in the slot S1, The flow proceeds to step S6.

  Next, the mounting position determination unit 11 generates a warning by using an audible means for sounding a buzzer or the like and a visual means for blinking the light by the alarm control unit 13 (step S6).

  Next, when it is determined that there is no mounting error, the mounting position determination unit 11 controls the application setting unit 12 and the application unit 15 to perform automatic setting of application information. Application information matching the board ID is retrieved from the application unit 15 (step S3).

  Next, when the mounting position determination unit 11 searches the application unit 15 for application information that matches the read backboard ID, the flow proceeds to step S5. On the other hand, if the application information is not retrieved from the application unit 15, the flow proceeds to step S6 (step S4).

  Next, when the application information is retrieved, the CPU device 2 is mounted in the slot of the backboard 3, and at this point, the CPU device 3 is on the basis that the backboard 3 is in a live state such as power-on. Performs normal operation based on application information stored in the application unit 15 in advance (step S5).

  FIG. 7 shows an example in which the CPU device 2 is mounted in the slot S0 of the backboard 3 as an example. In step S3, the application information of the slot S0 is searched, and in step S4, the slot is set in the operation area of the CPU device 2. An example in which the application of S0 is expanded is shown. In this example, the CPU device 2 is set exclusively for the slot S0.

As described above, according to the module mounting system 1 of the first embodiment, the backboard 3 includes the IC tag 7 to which the unique backboard ID 8 for specifying the mounted CPU device 2 is specified. Before mounting on the backboard 3, the backreader ID is read by wireless communication from the IC tag 7 of the backboard 3 by the ID reader 10 of the CPU device 2 in a non-contact state, and the CPU device 2 is mounted based on the read result. Since it is determined whether or not there is a mistake, it is possible to detect whether or not a mounting error has occurred before mounting the CPU device 2 on the backboard 3. Further, since the CPU device 2 includes the application unit 15 in which an application for performing a predetermined operation is stored in advance, application setting can be automatically performed.
Therefore, it is possible to detect whether or not a mounting error has occurred before mounting the module on the board, and it is possible to automatically set application information. As a result, human errors can be automatically eliminated, and application management and maintainability can be improved.

That is, the CPU device 22 used in the module mounting system 9 of the second embodiment is substantially the same as that of the first embodiment except that the shape is different from that of the first embodiment. However, in the second embodiment, the CPU device 22 obtains the slot ID as a box ID and determines the mounting box, thereby detecting the mounting error in the box and automatically setting the application information. To do before. By changing the shape of the CPU device in this way, there is an advantage that variations can be given to the use for mounting the CPU device. In the second embodiment, only one CPU device 22 is shown for the sake of simplicity, but actually, the same number as in the first embodiment is used.

  In the first and second embodiments, the example in which the ID information specifying the CPU device mounted on the backboard is given to the IC tag has been described, but an IC card may be used instead of the IC tag. Moreover, although the number of the backboard slots has been described as an example in which eight slots are provided, the number can be arbitrarily changed according to the purpose and application. Furthermore, the module mounted on the backboard has been described with reference to an example of a CPU device. However, the present invention is not limited to this, and any module having a function for performing a predetermined operation such as various control functions or a memory function may be used.
