[0004] [Patent Document 1] JP 2002-125373 A [Patent Document 2] JP 2015-102901 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the conventional configuration has room for improvement in terms of support for a multi-slot width module that is connected to a frame controller through multiple slots. For example, the conventional configuration cannot simultaneously stop the power supply to each slot occupied by the multi-slot width module. As a result, excessive current may flow through the connectors of some slots, which may result in damage to the internal circuitry of the multi-slot width module.

[0006] An object of the present disclosure is to enable a frame controller to accommodate multiple slot wide modules. [Means for solving the problem]

[0007] According to the present disclosure, a measurement device includes: (1) Multiple slots to which modules can be connected; a power supply management unit that controls the supply of power to the modules connected to the plurality of slots; a display unit for displaying a measurement signal acquired by the module; Equipped with The power supply management unit When an abnormality is detected in any of the plurality of slots, all of the slots to which the module connected to the slot in which the abnormality is detected is connected are identified as target slots; The supply of power to the identified target slot is stopped.

[0008] In this way, when an abnormality is detected in any of the multiple slots, the measurement device identifies all slots to which the module connected to the slot in which the abnormality was detected is connected and stops the power supply to that slot. Therefore, the measurement device can simultaneously stop the power supply to the modules connected to the slot in which the abnormality was detected. Therefore, the measurement device can handle a multiple-slot width module connected via multiple slots.

[0012] In this way, the measuring device creates a power control table based on the connector information for each connected module, and uses the power table to identify the target slot to which power supply is to be stopped. Therefore, the measuring device can appropriately identify the target slot to which power supply is to be stopped according to the connection status of the modules.

[0014] In this way, the measurement device obtains connector information for a connected module based on the model name of the module, and therefore the measurement device can obtain connector information corresponding to the module without extensive communication with the module.

[0015] (5) In the measuring device of (3), The power management unit may acquire the connector information for each of the modules connected to the measurement device from the corresponding module.

[0016] In this way, the measurement device obtains connector information for each connected module from that module, and is therefore able to obtain accurate connector information corresponding to the module.

[0017] (6) In any of the measuring devices described in (1) to (5), a plurality of power supply control units provided corresponding to the plurality of slots and configured to switch between supplying and not supplying power to the modules connected to the respective slots; The power management unit may control the plurality of power control units to control the supply of power to the modules connected to the plurality of slots.

[0018] In this way, the measurement device includes a power supply control unit for each slot that switches between supplying and not supplying power to the connected module, and the power management unit controls the power supply control unit to control the supply of power to the module. Therefore, the measurement device can easily switch the power supply to each slot depending on the slot in which an abnormality is detected.

[0019] (7) In the measuring device of (6), an abnormality detection unit that detects an abnormality in the power supply to the module connected to the slot in the plurality of slots based on information acquired from the plurality of power supply control units; When an abnormality is detected in any of the plurality of slots by the abnormality detection unit, the power management unit may identify as target slots all of the slots to which the module connected to the slot in which the abnormality was detected is connected.

[0020] In this manner, the measurement device detects abnormalities in a plurality of slots using an abnormality detection unit that detects abnormalities in the power supply to the modules connected to the slots. Therefore, the measurement device can appropriately detect abnormalities in each slot and switch the power supply.

[0021] (8) In any one of the measuring devices described in (1) to (7), a plurality of module communication units provided corresponding to the plurality of slots and configured to communicate with the modules connected to the respective slots; When the power management unit receives abnormality information indicating an abnormality from a module that communicates with one of the multiple module communication units, the power management unit may identify all of the slots to which the modules connected to the slot corresponding to the module communication unit are connected as target slots.

[0022] In this way, the measurement device detects an abnormality based on receiving abnormality information from the module, and is therefore able to appropriately switch the power supply depending on the abnormality on the module side.

[0023] According to the present disclosure, a measurement system includes: (9) a module; A measuring device connectable to the module; A measurement system comprising: The measuring device is A plurality of slots to which the modules can be connected; a power supply management unit that controls the supply of power to the modules connected to the plurality of slots; a display unit for displaying a measurement signal acquired by the module; Equipped with The power supply management unit When an abnormality is detected in any of the plurality of slots, all of the slots to which the module connected to the slot in which the abnormality is detected is connected are identified as target slots; The supply of power to the identified target slot is stopped.

[0024] In this way, when an abnormality is detected in any of the multiple slots, the measurement system identifies all slots to which the module connected to the slot in which the abnormality was detected is connected and stops the power supply to that slot. Therefore, the measurement system can simultaneously stop the power supply to the modules connected to the slot in which the abnormality was detected. Therefore, the measurement system can handle a multiple-slot width module that is connected via multiple slots.

[0027] According to one embodiment of the present disclosure, a frame controller can be made accommodating multiple slot wide modules. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a diagram illustrating an example of the appearance of a frame controller according to an embodiment. [Diagram 3] FIG. 2 is a diagram illustrating an example of an external appearance of a module according to an embodiment. [Figure 4] 1 is a block diagram showing an example of the configuration of a frame system according to an embodiment; [Diagram 5] 10 is a flowchart illustrating an example of the operation of a frame controller according to an embodiment. [Figure 6] 11A and 11B are diagrams illustrating an example of module implementation and an example of a power supply control table. [Figure 7] 1 is a block diagram showing an example of the configuration of a frame system according to an embodiment; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] <Comparative Example> FIG. 1 is a diagram showing a configuration of a frame system 9 according to a comparative example. The frame system 9 includes a frame controller 90 according to the comparative example and modules 94 (94a, 94b). The frame controller 90 according to the comparative example has a plurality of slots into which the modules 94 can be mounted. The modules 94 provide various information, such as measurement values, to the frame controller 90. The modules 94 have a connector for connecting to the frame controller 90. A user mounts the module 94 in the slot, thereby connecting the connector of the module 94 to the frame controller 90.

[0030] The connector of the module 94 has signal lines for receiving power as a driving power source and for receiving operation control signals from the frame controller 90. The module 94 connected to the frame controller 90 performs operations according to the type of the module 94, such as obtaining electrical signals indicating the measurement values ​​of various physical quantities based on the operation control signals. The module 94 transmits information such as the measurement values ​​of the physical quantities obtained via the connector to the frame controller 90.

[0031] The frame controller 90 according to the comparative example includes a power supply control unit 91 (91a, 91b), a module communication unit 92 (92a, 92b), and an abnormality detection unit 93. The frame controller 90 includes one power supply control unit 91 (91a, 91b) and one module communication unit 92 (92a, 92b) for each slot.

[0032] The power supply control unit 91 has a function of switching on and off the supply of power as a driving power source to the module 94 mounted in the corresponding slot. The power supply control unit 91 also has a function of acquiring information such as voltage and current regarding the power supply to the module 94 as a driving power source.

[0033] The module communication unit 92 has a function of communicating with the module 94, acquiring information including the model name of the module 94, and controlling the operation of the module 94. The information transmitted and received by the module communication unit 92 between the module 94 includes a signal for the frame controller 90 to recognize the insertion and removal of the module 94.

[0034] The abnormality detection unit 93 has a function of detecting an abnormality in each slot based on information acquired by the power supply control unit 91. When the abnormality detection unit 93 detects an abnormality in the power supply in a certain slot, it can control the power supply control unit 91 in that slot to stop the power supply.

[0035] In the above configuration, the power supply control unit 91 detects a slot in which a module 94 is installed, and starts supplying power to the module 94 attached to that slot. Next, the module communication unit 92 communicates with the module 94 to obtain the model name of the connected module 94. The abnormality detection unit 93 constantly monitors each power supply control unit 91. When the abnormality detection unit 93 detects an abnormality in the power supply control unit 91 of any slot, it instructs the power supply control unit 91 of that slot to stop supplying power to the module 94.

[0036] Here, consider a situation in which a multiple slot width module is connected to a frame controller 90 according to a comparative example. A multiple slot width module is a module that occupies multiple slots per module. The multiple slot width module may have multiple connectors and be connected to the frame controller 90 via multiple slots.

[0037] In a multiple slot width module, there is an upper limit to the amount of current that can flow per connector. Therefore, in order to secure the power supply capacity, it is conceivable to connect the power supply of the frame controller 90 to multiple connectors in parallel and supply power in parallel. In such a multiple slot width module in which power supplies are connected in parallel internally, if the timing of starting and stopping the power supply differs depending on the connector, the current will concentrate on the connector that stops the power supply later, which may result in damage to the internal circuit. Therefore, the start and stop of the power supply to the multiple slot width module must be performed simultaneously for all connectors in order to prevent damage to the multiple slot width module.

[0038] However, when a multi-slot width module is connected to the frame controller 90 according to the comparative example, the power supply to the multiple connectors cannot be stopped simultaneously. Therefore, in the frame controller 90 according to the comparative example, it is possible to prohibit parallel connection of power supplies. However, even if the power supplies are not connected in parallel inside the multi-slot width module, the internal circuit may be damaged if the power supply to all connectors is not stopped simultaneously. For example, if a signal is sent to a circuit connected to a connector to which the power supply has been stopped first, the circuit may be damaged due to latch-up or the like. Therefore, in the frame controller 90 according to the comparative example, even if parallel connection of power supplies is prohibited, there are design constraints from the viewpoint of preventing damage to the internal circuit.

[0039] Thus, the frame controller 90 according to the comparative example has room for improvement in terms of compatibility with modules with multiple slot widths.

[0040] <Embodiment> Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In each drawing, parts having the same configuration or function are denoted by the same reference numerals. In the description of this embodiment, duplicated descriptions of the same parts may be omitted or simplified as appropriate.

[0041] Fig. 2 is a diagram showing an example of the appearance of a frame controller 10 according to an embodiment. Fig. 3 is a diagram showing an example of the appearance of a module 20 according to an embodiment. Fig. 4 is a block diagram showing an example of the configuration of a frame system 1 according to an embodiment. As shown in Fig. 4, the frame system 1 as a measurement system includes a frame controller 10 and a module 20.

[0042] As shown in FIG. 2, the frame controller 10 serving as a measuring device includes a plurality of slots 17, a display unit 18, and an operation unit 19.

[0043] The slot 17 is a receptacle for mounting the module 20. The slot 17 is connectable to the module 20. The frame controller 10 may include a connection portion inside the slot 17 for electrically and mechanically connecting to a connector 25 (see FIG. 3) of the module 20.

[0044] The display unit 18 is a monitor that displays information to the user. The display unit 18 displays, for example, the waveform of a signal acquired by the module 20. The display unit 18 may be, for example, a liquid crystal panel display or an organic EL (Electro Luminescence) display. The display unit 18 may be configured as a touch screen (touch panel) that is integrally provided with the operation unit 19.

[0045] The operation unit 19 includes one or more input interfaces that accept operations from a user. The operation unit 19 is, for example, but is not limited to, a physical key, a capacitive key, a pointing device, or a touch screen that is provided integrally with the display unit 18. At least one of the display unit 18 and the operation unit 19 may be configured integrally with the frame controller 10, or may be provided separately.

[0046] The module 20 provides information such as measurements to the frame controller 10. The module 20 may be various plug-in modules such as a tunable light source, an optical power meter, an optical attenuator, or an optical switch. Alternatively, the module 20 may obtain signals (measurement signals) related to electrical measurements such as voltage, current, and power, as well as measurements related to physical quantities other than light, such as temperature, pressure, flow rate, strain, acceleration, pH, or humidity.

[0047] 3, the module 20 includes a connector 25. The connector 25 can be electrically and mechanically connected to a connection portion provided inside the slot 17 of the frame controller 10. A user mounts the module 20 in the slot 17 to connect the connector 25 of the module 20 to the frame controller 10.

[0048] The connector 25 of the module 20 has signal lines for receiving power as a driving power source and for receiving operation control signals from the frame controller 10. The module 20 connected to the frame controller 10 obtains electrical signals indicating the measurement values ​​of various physical quantities based on the operation control signals. The module 20 transmits the obtained measurement values ​​of the physical quantities to the frame controller 10 via the connector 25. The frame controller 10 displays the waveforms of the measurement values ​​of the physical quantities provided from the module 20 on the display unit 18.

[0049] 3 occupies one slot 17 when connected to the frame controller 10, the module 20 may occupy multiple slots 17 and be connected to the frame controller 10. As described above, a module 20 occupying multiple slots 17 is referred to as a "multiple slot width module." The multiple slot width module may include multiple connectors 25 and be connected to the frame controller 10 via multiple slots 17. The number of slots 17 occupied by the multiple slot width module when connected to the frame controller 10 may not be the same as the number of connectors 25 included in the multiple slot width module. For example, the multiple slot width module may have a portion that occupies a slot 17 but does not include a connector 25 corresponding to that slot 17.

[0050] 4 shows an example in which two modules 20 (20a, 20b) are connected to the frame controller 10. The module 20a has a shape that occupies one slot 17, and includes one connector 25. The module 20b has a shape that occupies two slots 17, and includes two connectors 25. The module 20b corresponds to a multiple slot width module.

[0051] As shown in FIG. 4, the frame controller 10 includes, as internal components thereof, a power supply control unit 11 (11a, 11b, 11c), a module communication unit 12 (12a, 12b, 12c), an abnormality detection unit 13, a power supply management unit 14, a table holding unit 15, and a storage unit 16. The frame controller 10 includes one power supply control unit 11 (11a, 11b, 11c) and one module communication unit 12 (12a, 12b, 12c) for each slot 17. In the example of FIG. 4, the module 20a is connected to the power supply control unit 11a and the module communication unit 12a via a connector 25. The module 20b is connected to the power supply control units 11b, 11c and the module communication units 12b, 12c via a connector 25.

[0052] The power supply control unit 11 has a function of switching on and off the supply of power as a driving power source to the module 20 mounted in the corresponding slot 17 based on the control of the power management unit 14. The power supply control unit 11 also has a function of acquiring information such as voltage and current regarding the power supply to the module 20 as a driving power source.

[0053] The module communication unit 12 has a function of communicating with the module 20, acquiring information including the model name of the module 20, and controlling the operation of the module 20. The information transmitted and received by the module communication unit 12 between the module 20 includes a signal for the frame controller 90 to recognize the insertion and removal of the module 20. The module communication unit 12 has a function of notifying the power management unit 14 of the model name acquired from the module 20.

[0054] The abnormality detection unit 13 has a function of detecting an abnormality in each slot 17 based on information acquired by the power supply control unit 11. The abnormality detection unit 13 notifies the power supply management unit 14 of the detected abnormality information. The abnormality information may include, for example, the slot number of the slot 17 in which the abnormality was detected, the type of abnormality, etc. The type of abnormality may include, for example, the power supply current, voltage, power, user operation abnormality for the module 20, and input / output abnormality of the module 20, etc.

[0055] The table storage unit 15 stores a power supply control table. The power supply control table is information indicating, for each of the modules 20 connected to the frame controller 10, the slot 17 to which the module 20 is connected via the connector 25. An example of the power supply control table will be described later with reference to FIG.

[0056] The storage unit 16 stores connector information. The connector information is information indicating a correspondence between the type name of the module 20, the slot width of the slot 17 occupied by the module 20 identified by the type name, and the arrangement of the slots 17 connected by the connectors 25 in the slot width. The slot width is the number of slots 17 occupied by the module 20. For example, the slot width of the module 20a in FIG. 4 is 1. The slot width of the module 20b is 2. For example, if the presence of connection by the connector 25 is represented by "1" and the absence of connection is represented by "0", the arrangement of the slots 17 connected by the connectors 25 of the module 20a can be represented as [1]. The arrangement of the slots 17 connected by the connectors 25 of the module 20a can be represented as

[11] .

[0057] As shown in FIG. 4, the module 20 (20a, 20b) includes a storage unit 21 (21a, 21b). The storage unit 21 of the module 20 stores connector information for the module 20. That is, the connector information stored in the storage unit 21 of the module 20 is information indicating the model name of the module 20, the slot width of the slot 17 occupied by the module 20, and the arrangement of the slots 17 connected by the connectors 25 in the slot width. The frame controller 10 acquires the connector information from the module 20 in response to the connection of the module 20. If the acquired connector information is not stored in the storage unit 16, the frame controller 10 adds the connector information to the storage unit 16 for storage.

[0058] The power management unit 14 has a function of managing the operation of the power control units 11 (11a, 11b, 11c) of each slot 17. Specifically, the power management unit 14 creates a power control table based on the model name information of the module 20 acquired via the module communication unit 12 in response to the connection of the module 20 and the connector information stored in the storage unit 16, and causes the table storage unit 15 to store the power control table.

[0059] When the abnormality detection unit 13 detects an abnormality in any of the slots 17, the power management unit 14 refers to the power control table to identify all slots 17 used by the modules 20 connected to the slot 17 in which the abnormality was detected. The power management unit 14 controls the power control units 11 corresponding to each identified slot 17 to stop the power supply from the power control units 11. Therefore, when a multiple-slot width module is connected, the frame controller 10 according to this embodiment can simultaneously stop the power supply to the multiple connectors 25 of the multiple-slot width module. Therefore, the frame controller 10 can handle the multiple-slot width module.

[0060] In this embodiment, each of the components shown as blocks in FIG. 4 is realized by separate hardware, but the present invention is not limited to such a configuration. For example, two or more components may be realized by common hardware. Specifically, for example, the table holding unit 15 and the storage unit 16 may be configured by the same memory. Also, at least a part of each of the components shown in FIG. 4 may be realized by a general-purpose processor executing a program. That is, at least a part of each of the components shown in FIG. 4 may be realized by software. For example, the abnormality detection unit 13 and the power management unit 14 may be realized by software. Also, each of the frame controller 10 and the module 20 may be realized by a single device or by the cooperation of multiple devices.

[0061] Fig. 5 is a flowchart showing an example of the operation of the frame controller 10 according to an embodiment. The operation of the frame controller 10 described with reference to Fig. 5 may correspond to one of the control methods of the frame controller 10. The operation of each step in Fig. 5 may be executed based on the control of the power management unit 14 of the frame controller 10. Below, an example will be described in which the operation in Fig. 5 starts in a state in which two modules 20 (20a, 20b) are connected to the slots 17 of the frame controller 10 as in Fig. 4.

[0062] In step S1, the power management unit 14 starts power supply to each of the modules 20 connected to the frame controller 10. Specifically, for example, the power management unit 14 controls the power control unit 11a to start power supply to the module 20a. The power management unit 14 controls the power control units 11b and 11c to start power supply to the module 20b.

[0063] In step S2, the power management unit 14 acquires the model name from each of the modules 20 connected to the frame controller 10. Specifically, the power management unit 14 controls, for example, the module communication units 12a, 12b, and 12c to acquire the model names of the modules 20a and 20b from the modules 20. The power management unit 14 refers to the storage unit 16 and determines whether or not connector information related to the model name is stored in the storage unit 16. If the connector information is not stored in the storage unit 16, the power management unit 14 adds the connector information of the module 20 to the storage unit 16.

[0064] In step S3, the power management unit 14 creates a power control table based on the model name recognized in step S2. Specifically, the power management unit 14 refers to the connector information stored in the storage unit 16 and acquires the slot width and the arrangement of the slots 17 connected by the connectors 25 for each of the modules 20 connected to the frame controller 10. The power management unit 14 creates a power control table based on the acquired slot width and the arrangement of the connected slots 17.

[0065] FIG. 6 is a diagram showing an example of an implementation of the module 20 and an example of the power supply control table 100. In the example of FIG. 6, the frame controller 10 has nine slots 17. The nine slots 17 are identified by slot numbers (Slot No.) "1" to "9". In the example of FIG. 6, four modules 20c, 20d, 20e, and 20f are connected to the frame controller 10. The slot width of the module 20c is 3. The module 20c occupies the slots 17 with slot numbers "1" to "3". The arrangement of the slots 17 connected by the connectors 25c1 and 25c2 of the module 20c can be expressed as

[0101] . The slot width of the module 20d is 2. The module 20d occupies the slots 17 with slot numbers "4" and "5". The arrangement of the slots 17 connected by the connectors 25d1 and 25d2 of the module 20d can be expressed as

[11] . The slot width of module 20e is 1. Module 20e occupies slot 17 with slot number "6." The arrangement of slots 17 connected by connector 25e of module 20e can be expressed as [1]. The slot width of module 20f is 3. Module 20f occupies slots 17 with slot numbers "7" to "9." The arrangement of slots 17 connected by connectors 25f1 and 25f2 of module 20f can be expressed as

[0011] .

[0066] 6, MODULE_ID[n] indicates the connection state of all slots 17 to which the connector 25 of the module 20 occupying the slot 17 with slot number "n" is connected with a bit "1", and indicates the connection state of the other slots 17 with a bit "0", where n is a natural number (n: 1, 2, ...).

[0067] For example, the slots 17 with slot numbers "1" to "3" are occupied by the module 20c. The connectors 25c1 and 25c2 of the module 20c are connected to the slots 17 with slot numbers "1" and "3". Therefore, as shown in FIG. 6, MODULE_ID[1] to MODULE_ID[3] are all [000000101]. Here, the lower three bits of MODULE_ID[1] to MODULE_ID[3] are the same as the arrangement

[0101] of the slots 17 connected by the connectors 25c1 and 25c2 of the module 20c (121). Similarly, the slots 17 with slot numbers "4" and "5" are occupied by the module 20d. The connectors 25d1 and 25d2 of the module 20d are connected to the slots 17 with slot numbers "4" and "5". Therefore, MODULE_ID[4] and MODULE_ID[5] are both [000011000]. Slot 17 with slot number "6" is occupied by module 20e. Connector 25e of module 20e connects to slot 17 with slot number "6". Therefore, MODULE_ID[6] is [000100000]. Slots 17 with slot numbers "7" to "9" are occupied by module 20f. Connectors 25f1 and 25f2 of module 20f connect to slots 17 with slot numbers "8" and "9". Therefore, MODULE_ID[7] to MODULE_ID[9] are both [110000000].

[0068] The power supply manager 14 may create the power supply control table from the connector information acquired from the module 20 via the module communication unit 12 .

[0069] Returning to the explanation of Fig. 5, in step S4, the power management unit 14 determines whether or not the abnormality detection unit 13 has detected an abnormality in any of the slots 17. Specifically, the power management unit 14 may determine that an abnormality has been detected when abnormality information is received from the abnormality detection unit 13. If the power management unit 14 detects an abnormality (YES in step S4), it proceeds to step S5, and if not (NO in step S4), it continues to wait.

[0070] In step S5, the power management unit 14 identifies, as target slots, all slots 17 to which the connectors 25 of the modules 20 connected to the slot 17 in which the abnormality was detected are connected. The target slots are the slots 17 to which power should be cut off. Specifically, the power management unit 14 identifies the slot number of the slot 17 in which the abnormality was detected by referring to the abnormality information received from the abnormality detection unit 13 in step S4. The power management unit 14 identifies, by referring to the power control table, all slots 17 to which the connectors 25 of the modules 20 connected to the slot 17 of the identified slot number are connected.

[0071] For example, in the case where the power supply control table is shown in Fig. 6, it is assumed that the slot number of the slot 17 in which the abnormality detection unit 13 detected an abnormality is "3." In this case, the power supply management unit 14 refers to MODULE_ID[3] indicating the connection relationship for the slot 17 with slot number "3." Since MODULE_ID[3] = [000000101], the power supply management unit 14 identifies the slots 17 with slot numbers "1" and "3" as target slots.

[0072] In step S6, the power management unit 14 controls each power control unit 11 corresponding to the target slot so as to simultaneously stop the power supply to all the target slots identified in step S5. As a result, the power supply to all the connectors 25 connected to the slot 17 in which the abnormality has occurred is simultaneously stopped. After completing the process of step S6, the power management unit 14 ends the process of the flowchart shown in FIG.

[0073] As described above, the frame controller 90 according to the comparative example can only cut off the power supply to the slot in which an abnormality is detected. In contrast, when an abnormality is detected in any of the multiple slots 17, the frame controller 10 as a measurement device according to the present embodiment identifies, as target slots, all slots 17 to which the modules 20 connected to the slot 17 in which the abnormality is detected are connected. The frame controller 10 stops the supply of power to the target slots. Therefore, the frame controller 10 can simultaneously stop the supply of power to the modules 20 connected to the slot 17 in which the abnormality is detected.

[0074] Furthermore, the frame controller 10 uses the power supply control table to identify the slots 17 to which power supply is to be stopped simultaneously. Therefore, the frame controller 10 can appropriately cut off the power supply without depending on the combination of types of modules 20, the positions of the slots 17 in which the modules 20 are mounted, and the positions of the slots 17 in which an abnormality has occurred. Furthermore, in the frame controller 10, the power supply management unit 14 controls the operation of each power supply control unit 11. Therefore, even if an abnormality occurs simultaneously in multiple slots 17 to which multiple slot width modules are connected, it is possible to prevent abnormal operation such as double power cutoff. Furthermore, the frame controller 10 can simultaneously cut off the power supplies of multiple different modules 20 even if an abnormality occurs simultaneously in those modules.

[0075] In this way, the frame controller 10 allows the power supplies from the connectors 25 to be connected in parallel inside the module 20 in a multiple slot width module, thereby increasing the load current capacity inside one module 20. Furthermore, even if the power supplies are not connected in parallel, the frame controller 10 can reduce the risk of failure when communication and control signals are connected between the slots 17 inside the module 20.

[0076] In the frame system 1 described with reference to Fig. 4, the frame controller 10 includes the abnormality detection unit 13, but the abnormality detection unit may be included on the module side. Such a configuration will be described with reference to Fig. 7. Hereinafter, the same reference numerals will be used to designate the same configuration as Fig. 4, and detailed description will be omitted.

[0077] Fig. 7 is a block diagram showing a configuration example of a frame system 2 according to an embodiment. The frame system 2 includes a frame controller 30 and modules 40 (40a, 40b). As shown in Fig. 7, the frame controller 30 includes, as internal configuration of the device, a power supply control unit 11 (11a, 11b), a module communication unit 12 (12a, 12b), a power supply management unit 14, a table holding unit 15, and a storage unit 16. The module 40 (40a, 40b) includes a storage unit 41 (41a, 41b) and an abnormality detection unit 42 (42a, 42b).

[0078] In the configuration example of FIG. 7, the frame controller 30 does not include an abnormality detection unit. The abnormality detection unit 42 included in the module 40 detects an abnormality in the module 40. When the abnormality detection unit 42 detects an abnormality, the module 40 notifies the power supply management unit 14 of the detected abnormality information via the connector 25 and the module communication unit 12. The abnormality information may include, for example, the slot number of the slot 17 in which the abnormality is detected, the type of abnormality, and the like. The type of abnormality may further include, for example, the power supply current, voltage, power, user operation abnormality for the module 40, and input / output abnormality of the module 20, as well as the internal temperature of the module 40, the internal air pressure of the module 40, an internal FAN alarm of the module 40, user operation abnormality for the module 40, abnormality due to vibration or impact of the module 40, and humidity abnormality (condensation) inside the module 40.

[0079] In such a configuration, the power management unit 14 detects an abnormality based on receiving abnormality information from the module 40. Therefore, the frame controller 30 can appropriately switch the power supply depending on the abnormality on the module 40 side. Note that both the frame controllers 10, 30 and the modules 20, 40 may include an abnormality detection unit, and the power management unit 14 may switch the power supply depending on an abnormality detected by either of these abnormality detection units.

[0080] The present disclosure is not limited to the above-described embodiments. For example, multiple blocks shown in the block diagram may be integrated, or one block may be divided. Multiple steps shown in the flowchart may be executed in parallel or in a different order depending on the processing capacity of the device executing each step, or as necessary, instead of being executed in chronological order as described. Other modifications are possible without departing from the spirit of the present disclosure. [Explanation of symbols]
