Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the conventional configuration had room for improvement in terms of coping with a multi-slot width module connected to the frame controller via a plurality of slots. For example, the conventional configuration could not simultaneously stop the power supply to each slot occupied by the multi-slot width module. Therefore, an excessive current could flow through the connectors of some slots, and as a result, there was a possibility of damaging the internal circuit of the multi-slot width module.

[0006] The purpose of this disclosure is to enable the frame controller to support multiple slot width modules. [Means for solving the problem]

[0007] According to this disclosure, the measuring device is (1) Multiple slots to which modules can be connected, A power management unit that controls the supply of power to the modules connected to the plurality of slots, A display unit that displays the measurement signal acquired by the module, Equipped with, The aforementioned power management unit, If an abnormality is detected in any of the aforementioned slots, all of the slots to which the module connected to the slot where the abnormality was detected is connected are identified as target slots. The power supply to the identified target slot is stopped.

[0008] Thus, when the measuring device detects an abnormality in any of the multiple slots, it identifies all the slots to which the module connected to the slot where the abnormality was detected is connected, and stops the power supply to those slots. Therefore, the measuring device can simultaneously stop the power supply to the module connected to the slot where the abnormality was detected. Thus, the measuring device can handle multi-slot width modules connected via multiple slots.

[0009] (2) In the measuring device of (1), Each of the modules connected to the measuring device is further provided with a holding unit that holds a power control table, which is information indicating the slot to which the module is connected. The power management unit may, when it detects an abnormality in any of the multiple slots, refer to the power control table to identify the target slot.

[0010] In this way, when the power management unit detects an abnormality in any of the multiple slots, it refers to the power control table to identify the affected slot. Therefore, the measuring device can appropriately identify all slots to which the module connected to the slot where the abnormality was detected is connected, and stop the power supply to those slots.

[0011] (3)(2) In the measuring device, The aforementioned power management unit, For each of the modules connected to the measuring device, connector information is obtained, including the arrangement of the slots for the module to connect to the measuring device. Based on the connector information for each of the modules connected to the measuring device, the power control table is created. The created power control table may be held in the holding unit.

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

[0013] (4)(3) In the measuring device, The aforementioned power management unit, For each of the modules connected to the measuring device, the model name of the module is obtained. The connector information may be obtained based on the model name for each of the modules connected to the measuring device.

[0014] In this way, the measuring device acquires connector information for a module based on its model name. Therefore, the measuring device can acquire connector information corresponding to a module without requiring extensive communication with the module.

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

[0016] Thus, the measuring device acquires the connector information about each of the connected modules from each of the modules. Therefore, the measuring device can acquire accurate connector information corresponding to the modules.

[0017] (6) In any of the measuring devices of (1) to (5), The measuring device further includes a plurality of power control units provided corresponding to the plurality of slots and switching the presence or absence of power supply to the modules connected to the slots. The power management unit may control the plurality of power control units to control the power supply to the modules connected to the plurality of slots.

[0018] Thus, the measuring device includes a power control unit for switching the presence or absence of power supply to the connected modules for each slot, and the power management unit controls the power control unit to control the power supply to the modules. Therefore, the measuring device can easily switch the power supply in each slot according to the slot in which an abnormality is detected.

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

[0020] In this way, the measuring device detects abnormalities in the power supply to the modules connected to each slot using an abnormality detection unit. Therefore, the measuring device can appropriately detect abnormalities in each slot and switch the power supply accordingly.

[0021] (8) In any of the measuring devices described in (1) to (7), The system further comprises a plurality of module communication units, each provided in relation to the plurality of slots and communicating with the modules connected to those slots, The power management unit may, when it receives abnormal information indicating an abnormality from a module that has communicated with the module communication unit via any of the plurality of module communication units, identify all the slots to which the module connected to the slot corresponding to the module communication unit is connected as target slots.

[0022] In this way, the measuring device detects abnormalities based on abnormality information received from the module, and can appropriately switch the power supply in response to the abnormality on the module side.

[0023] According to this disclosure, the measurement system is (9) Modules and, A measuring device that can be connected to the aforementioned module, A measuring system comprising, The measuring device is, Multiple slots to which the aforementioned module can be connected, A power management unit that controls the supply of power to the modules connected to the plurality of slots, A display unit that displays the measurement signal acquired by the module, Equipped with, The aforementioned power management unit, If an abnormality is detected in any of the aforementioned slots, all of the slots to which the module connected to the slot where the abnormality was detected is connected are identified as target slots. The power supply to the identified target slot is stopped.

[0024] Thus, when the measurement system detects an anomaly in any of the multiple slots, it identifies all the slots to which the module connected to the slot where the anomaly was detected is connected, and shuts off the power supply to those slots. Therefore, according to the measurement system, the power supply to the module connected to the slot where the anomaly was detected can be shut off simultaneously. Thus, the measurement system can handle multi-slot width modules connected via multiple slots.

[0025] According to this disclosure, the program is (10) Processor and Multiple slots to which modules can be connected, A display unit that displays measurement signals acquired by the modules connected to the plurality of slots, A program for controlling a measuring device equipped with, The aforementioned processor, A procedure for identifying all slots to which the module connected to the slot where the abnormality was detected is connected as target slots when an abnormality is detected in any of the aforementioned multiple slots, A procedure for stopping the power supply to the identified target slot, Make it run.

[0026] Thus, when a program-based measuring device detects an abnormality in any of its multiple slots, it identifies all slots to which the module connected to the slot where the abnormality was detected is connected, and shuts off the power supply to those slots. Therefore, this measuring device can simultaneously shut off the power supply to the module connected to the slot where the abnormality was detected. Thus, this measuring device can accommodate multi-slot width modules connected via multiple slots. [Effects of the Invention]

[0027] According to one embodiment of the present disclosure, the frame controller can be made compatible with multiple slot width modules. [Brief explanation of the drawing]

[0028] [Figure 1] This is a diagram showing the configuration of a frame system related to a comparative example. [Figure 2] This figure shows an example of the appearance of a frame controller according to one embodiment. [Figure 3] This figure shows an example of the appearance of a module according to one embodiment. [Figure 4] This is a block diagram showing an example configuration of a frame system according to one embodiment. [Figure 5] This flowchart shows an example of the operation of a frame controller according to one embodiment. [Figure 6] This figure shows an example of module implementation and an example of a power control table. [Figure 7] This is a block diagram showing an example configuration of a frame system according to one embodiment. [Modes for carrying out the invention]

[0029] <Comparative Example> Figure 1 shows the configuration of the frame system 9 according to the comparative example. The frame system 9 comprises a frame controller 90 and modules 94 (94a, 94b) according to the comparative example. The frame controller 90 according to the comparative example has multiple slots on which modules 94 can be mounted. Modules 94 provide the frame controller 90 with various information such as measured values. Modules 94 have connectors for connecting to the frame controller 90. The user connects the connectors of module 94 to the frame controller 90 by mounting module 94 in a slot.

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

[0031] The frame controller 90 in the comparative example comprises a power 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 control unit 91 (91a, 91b) and one module communication unit 92 (92a, 92b) for each slot.

[0032] The power control unit 91 has the function of switching whether or not to supply power as a drive power source to the module 94 installed in the corresponding slot. The power control unit 91 also has the function of acquiring information such as voltage and current regarding the power supply as a drive power source to the module 94.

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

[0034] The abnormality detection unit 93 has the function of detecting abnormalities in each slot based on information acquired by the power supply control unit 91. If 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 configuration described above, the power control unit 91 detects the slot on which the module 94 is installed and starts supplying power to the module 94 installed in 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 control unit 91. If the abnormality detection unit 93 detects an abnormality in the power control unit 91 of any slot, it instructs the power control unit 91 in that slot to stop supplying power to the module 94.

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

[0037] In multi-slot width modules, there is an upper limit to the amount of current that can flow through each connector. Therefore, to ensure sufficient power capacity, it is conceivable to connect the power supply of the frame controller 90 in parallel to multiple connectors and supply power in parallel. In such multi-slot width modules with power supplies connected in parallel, if the timing of starting and stopping power supply differs for each connector, current may concentrate on the connector whose power supply is stopped later, potentially damaging the internal circuitry. Therefore, to prevent damage to the multi-slot width module, the starting and stopping of power supply must be performed simultaneously for all connectors.

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

[0039] Thus, the frame controller 90 in the comparative example has room for improvement in terms of supporting 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, redundant descriptions of the same parts may be omitted or simplified as appropriate.

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

[0042] As shown in Figure 2, the frame controller 10, which serves as a measuring device, includes multiple slots 17, a display unit 18, and an operation unit 19.

[0043] Slot 17 is a socket for mounting module 20. Slot 17 is capable of connecting module 20. The frame controller 10 may include a connection part inside slot 17 for electrically and mechanically connecting to the connector 25 (see Figure 3) of 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 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 touchscreen (touch panel) provided integrally with the operation unit 19.

[0045] The operation unit 19 includes one or more input interfaces for receiving user input. The operation unit 19 is, for example, a physical key, a capacitive key, a pointing device, or a touchscreen integrated with the display unit 18, but is not limited to these. At least one of the display unit 18 and the operation unit 19 may be configured together with the frame controller 10 or provided as a separate unit.

[0046] Module 20 provides the frame controller 10 with information such as measured values. 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, Module 20 may acquire signals (measurement signals) related to electrical measurements such as voltage, current, and power, as well as measurements of physical quantities other than light, such as temperature, pressure, flow rate, strain, acceleration, pH, or humidity.

[0047] As shown in Figure 3, module 20 includes a connector 25. The connector 25 can be electrically and mechanically connected to a connection part provided inside slot 17 of frame controller 10. The user connects the connector 25 of module 20 to frame controller 10 by installing module 20 in slot 17.

[0048] The connector 25 of module 20 has signal lines for receiving power from the frame controller 10 and for receiving operation control signals. Module 20 connected to the frame controller 10 acquires electrical signals indicating measured values ​​of various physical quantities based on the operation control signals. Module 20 transmits the measured values ​​of the physical quantities acquired via the connector 25 to the frame controller 10. The frame controller 10 displays the waveforms of the measured values ​​of the physical quantities provided by module 20 on the display unit 18.

[0049] Note that the module 20 illustrated in Figure 3 occupies one slot 17 when connected to the frame controller 10, but the module 20 may occupy multiple slots 17 when connected to the frame controller 10. As mentioned above, a module 20 that occupies multiple slots 17 with a single module 20 is called a "multi-slot width module". A multi-slot width module may be equipped with multiple connectors 25 and connected to the frame controller 10 via multiple slots 17. The number of slots 17 occupied by a multi-slot width module when connected to the frame controller 10 does not have to be the same as the number of connectors 25 equipped on that multi-slot width module. For example, a multi-slot width module may have a portion that occupies a slot 17 but does not have a connector 25 corresponding to that slot 17.

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

[0051] As shown in Figure 4, the frame controller 10 comprises, internally, a power control unit 11 (11a, 11b, 11c), a module communication unit 12 (12a, 12b, 12c), an anomaly detection unit 13, a power management unit 14, a table holding unit 15, and a storage unit 16. The frame controller 10 has one power control unit 11 (11a, 11b, 11c) and one module communication unit 12 (12a, 12b, 12c) for each slot 17. In the example in Figure 4, module 20a is connected to the power control unit 11a and module communication unit 12a via connector 25. Module 20b is connected to the power control units 11b, 11c and module communication units 12b, 12c via connector 25.

[0052] The power control unit 11 has the function of switching whether or not to supply power as a drive power source to the module 20 mounted in the corresponding slot 17, based on the control of the power management unit 14. The power control unit 11 also has the function of acquiring information such as voltage and current regarding the power supply as a drive power source to the module 20.

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

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

[0055] The table holder 15, acting as a holding unit, holds the power control table. The power control table contains information indicating the slots 17 to which each module 20 connected to the frame controller 10 is connected via the connector 25. An example of the power control table will be described later with reference to Figure 6.

[0056] The memory unit 16 stores connector information. The connector information is information that shows the correspondence between the model name of the module 20, the slot width of the slot 17 occupied by the module 20 identified by that model name, and the arrangement of the slots 17 connected by the connector 25 within that slot width. The slot width is the number of slots 17 occupied by the module 20. For example, the slot width of module 20a in Figure 4 is 1. The slot width of module 20b is 2. For example, if we represent the presence of a connection by the connector 25 as "1" and the absence of a connection as "0", the arrangement of the slots 17 connected by the connector 25 of module 20a can be represented as [1]. The arrangement of the slots 17 connected by the connector 25 of module 20a can be represented as

[11] .

[0057] As shown in Figure 4, each module 20 (20a, 20b) includes a storage unit 21 (21a, 21b). The storage unit 21 of module 20 stores connector information for that module 20. Specifically, the connector information stored in the storage unit 21 of module 20 includes the model name of the module 20, the slot width of the slot 17 occupied by the module 20, and information indicating the arrangement of the slots 17 connected by the connector 25 within that slot width. The frame controller 10 obtains connector information from the module 20 according to its connection. If the obtained connector information is not stored in the storage unit 16, the frame controller 10 adds the connector information to the storage unit 16 and stores it there.

[0058] The power management unit 14 has the 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 from the module 20 model name information obtained via the module communication unit 12 and the connector information stored in the storage unit 16, according to the connection of the module 20, and stores it in the table holding unit 15.

[0059] If the abnormality detection unit 13 detects an abnormality in any of the slots 17, the power management unit 14 identifies all slots 17 used by the module 20 connected to the slot 17 where the abnormality was detected by referring to the power control table. The power management unit 14 controls the power control unit 11 corresponding to each identified slot 17 to stop the power supply from that power control unit 11. Therefore, the frame controller 10 according to this embodiment can simultaneously stop the power supply to multiple connectors 25 on multiple slot-width modules when multiple slot-width modules are connected. Thus, the frame controller 10 can support multiple slot-width modules.

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

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

[0062] In step S1, the power management unit 14 starts supplying power 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 supplying power to module 20a. The power management unit 14 controls the power control units 11b and 11c to start supplying power to module 20b.

[0063] In step S2, the power management unit 14 obtains 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 obtain the model names of modules 20a and 20b from the modules 20. The power management unit 14 refers to the storage unit 16 to determine whether 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 for that 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 to obtain the slot width and the arrangement of the slots 17 connected by the connector 25 for each module 20 connected to the frame controller 10. The power management unit 14 creates a power control table based on the obtained slot width and the arrangement of the connected slots 17.

[0065] Figure 6 shows an example of module 20 implementation and an example of power control table 100. In the example in Figure 6, the frame controller 10 has nine slots 17. The nine slots 17 are identified by slot numbers "1" to "9". In the example in Figure 6, four modules 20c, 20d, 20e, and 20f are connected to the frame controller 10. The slot width of module 20c is 3. Module 20c occupies slots 17 with slot numbers "1" to "3". The arrangement of slots 17 connected by connectors 25c1 and 25c2 of module 20c can be represented as

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

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

[0011] .

[0066] In the power control table 100 in Figure 6, MODULE_ID[n] indicates the connection status of all slots 17 to which the connector 25 of module 20 occupying slot 17 with slot number "n" is connected with a bit "1", and the connection status of all other slots 17 is indicated with a bit "0". Here, n is a natural number (n: 1, 2, ...).

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

[0101] of slots 17 connected by connectors 25c1 and 25c2 of module 20c (121). Similarly, slots 17 with slot numbers "4" and "5" are occupied by module 20d. Connectors 25d1 and 25d2 of module 20d are connected to 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 is connected 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 are connected to slots 17 with slot numbers "8" and "9". Therefore, MODULE_ID[7] to MODULE_ID[9] are all [110000000].

[0068] The power management unit 14 may also create a power control table from connector information obtained from module 20 via module communication unit 12.

[0069] Returning to the explanation of Figure 5, in step S4, the power management unit 14 determines whether 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 if it receives abnormality information from the abnormality detection unit 13. If the power management unit 14 has detected an abnormality (YES in step S4), it proceeds to step S5; otherwise (NO in step S4), it remains in standby mode.

[0070] In step S5, the power management unit 14 identifies all slots 17 to which the connector 25 of the module 20 connected to the slot 17 where the abnormality was detected is connected as target slots. Target slots are the slots 17 to which the power should be cut off. Specifically, the power management unit 14 identifies the slot number of the slot 17 where 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 all slots 17 to which the connector 25 of the module 20 connected to the slot 17 of the identified slot number is connected by referring to the power control table.

[0071] For example, if the power control table is shown in Figure 6, suppose the slot number of the slot 17 in which the abnormality detection unit 13 detected an abnormality is "3". In this case, the power management unit 14 refers to MODULE_ID[3] which indicates the connection relationship for slot 17 with slot number "3". Since MODULE_ID[3]=[000000101], the power management unit 14 identifies 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 to simultaneously stop the power supply to all target slots identified in step S5. As a result, the power supply to all connectors 25 connected to the slot 17 where the abnormality occurred is simultaneously stopped. After completing the process in step S6, the power management unit 14 terminates the process shown in the flowchart in Figure 5.

[0073] As mentioned above, the frame controller 90 in the comparative example can only shut off the power to the slot where an abnormality is detected. In contrast, the frame controller 10 as a measuring device according to this embodiment identifies all slots 17 to which the module 20 connected to the slot 17 where the abnormality was detected is connected as target slots when an abnormality is detected in any of the multiple slots 17. The frame controller 10 stops the power supply to those target slots. Therefore, the frame controller 10 can simultaneously stop the power supply to the module 20 connected to the slot 17 where the abnormality was detected.

[0074] Furthermore, the frame controller 10 uses a power control table to identify the slots 17 to which power supply will be stopped simultaneously. Therefore, the frame controller 10 can appropriately shut off power regardless of the combination of module types 20, the location of the slots 17 on which the modules 20 are installed, and the location of the slot 17 where the abnormality occurred. In addition, the power management unit 14 in the frame controller 10 coordinates the operation of each power control unit 11. Therefore, even if abnormalities occur simultaneously in multiple slots 17 to which multi-slot width modules are connected, abnormal operations such as double power cut-off can be prevented. Moreover, the frame controller 10 can simultaneously shut off the power to multiple different modules 20 even if abnormalities occur simultaneously in them.

[0075] Thus, with the frame controller 10, in a multi-slot width module, the power supplies from each connector 25 can be connected in parallel within the module 20, making it possible to increase the load current capacity within a single module 20. Furthermore, even when the power supplies are not connected in parallel, the frame controller 10 can reduce the risk of failure when there are connections for communication and control signals between slots 17 within the module 20.

[0076] In the frame system 1 described with reference to Figure 4, the frame controller 10 is equipped with an anomaly detection unit 13, but the anomaly detection unit may be provided on the module side. Such a configuration will be described with reference to Figure 7. Hereafter, components common to Figure 4 will be denoted by the same reference numerals, and detailed explanations will be omitted.

[0077] Figure 7 is a block diagram showing an example configuration of a frame system 2 according to one embodiment. The frame system 2 comprises a frame controller 30 and modules 40 (40a, 40b). As shown in Figure 7, the frame controller 30 comprises, internally, a power control unit 11 (11a, 11b), a module communication unit 12 (12a, 12b), a power management unit 14, a table holding unit 15, and a storage unit 16. The modules 40 (40a, 40b) comprise a storage unit 41 (41a, 41b) and an anomaly detection unit 42 (42a, 42b).

[0078] In the configuration example shown in Figure 7, the frame controller 30 does not have an abnormality detection unit. The abnormality detection unit 42 in the module 40 detects abnormalities within the module 40. When the abnormality detection unit 42 detects an abnormality, the module 40 notifies the power 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 was detected, and the type of abnormality. In addition to, for example, power supply current, voltage, power, user operation abnormalities, and input / output abnormalities of the module 20, the types of abnormalities may also include, the internal temperature of the module 40, the internal air pressure of the module 40, the internal FAN alarm of the module 40, user operation abnormalities on the module 40, vibration or shock abnormalities of the module 40, and humidity abnormalities (condensation) inside the module 40.

[0079] In this configuration, the power management unit 14 detects an anomaly based on receiving anomaly information from the module 40. Therefore, the frame controller 30 can appropriately switch the power supply in response to the anomaly on the module 40 side. Alternatively, both the frame controllers 10 and 30 and the modules 20 and 40 may be equipped with anomaly detection units, and the power management unit 14 may switch the power supply in response to an anomaly detected by any of these anomaly detection units.

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