[0008] However, the conventional structure has room for improvement in dealing with the multi-slot wide modules connected to the frame controller via multiple slots. For example, the conventional structure cannot stop the power supply to each slot occupied by the multi-slot wide module at the same time. Therefore, a large current may flow through the connectors of some slots, and as a result, the internal circuit of the multi-slot wide module may be damaged. Summary of the invention

[0009] An object of the present invention is to enable a frame controller to handle multi-slot width modules.

[0010] According to the present invention, a measuring device,

[0011] (1) The measuring device comprises:

[0012] Multiple slots, which enable the connection of modules;

[0013] a power management unit that controls supply of power to the modules connected to the plurality of slots; and

[0014] a display unit for displaying the measurement signal acquired by the module,

[0015] When an abnormality is detected in any one of the plurality of slots, the power management unit identifies all the slots connected to the modules connected to the slot in which the abnormality is detected as target slots, and stops the supply of power to the identified target slots.

[0016] Thus, when an abnormality is detected in any of the plurality of slots, the measuring device identifies all slots to which the module connected to the slot in which the abnormality is detected is connected and stops the power supply to the slot. Therefore, according to the measuring device, the power supply to the modules connected to the slot in which the abnormality is detected can be stopped at the same time. Therefore, the measuring device can handle multi-slot width modules connected via a plurality of slots.

[0017] (2) Based on the measuring device of (1), it can be formed as follows:

[0018] The device further comprises a storage unit that stores, for each of the modules connected to the measuring device, a power control table indicating information of the slot to which the module is connected.

[0019] When an abnormality is detected in any one of the plurality of slots, the power management unit refers to the power control table to identify the target slot.

[0020] Thus, when an abnormality is detected in any of the plurality of slots, the power management unit refers to the power control table to determine the target slot. Therefore, the measuring device can appropriately determine all slots connected to the module connected to the slot in which the abnormality is detected and stop the power supply to the slot.

[0021] (3) Based on the measuring device of (2), it can be formed as follows:

[0022] The power management unit acquires, for each of the modules connected to the measurement device, connector information including a configuration of the slot for connecting the module to the measurement device.

[0023] creating the power supply control table based on the connector information about each of the modules connected to the measurement device,

[0024] The storage unit is caused to store the created power supply control table.

[0025] Thus, the measuring device creates a power control table based on the connector information about each connected module, and determines the target slot to stop the power supply using the power control table. Therefore, the measuring device can appropriately determine the target slot to stop the power supply according to the connection status of the module.

[0026] (4) Based on the measuring device of (3), it can be formed as follows:

[0027] The power management unit acquires a model name of each of the modules connected to the measurement device,

[0028] The connector information is acquired based on the model name regarding each of the modules connected to the assay device.

[0029] In this way, the measurement device acquires the connector information about the connected module based on the model name of the module. Therefore, the measurement device can acquire the connector information corresponding to the module without involving a large amount of communication with the module.

[0030] (5) Based on the measuring device of (3), it can be formed as follows:

[0031] The power management unit acquires the connector information about each of the modules connected to the measurement device.

[0032] In this way, the measurement device acquires connector information about each of the connected modules, and thus the measurement device can acquire accurate connector information corresponding to the module.

[0033] (6) The measuring device according to any one of (1) to (5) may be configured as follows:

[0034] The measuring device further includes a plurality of power supply control units, which are provided corresponding to the plurality of slots and switch whether or not power is supplied to the modules connected to the slots.

[0035] The power management unit controls the plurality of power control units to control supply of power to the modules connected to the plurality of slots.

[0036] In this way, the measuring device has a power control unit for each slot that switches the supply of power to the connected module, and the power management unit controls the power control unit to control the supply of power to the module. Therefore, the measuring device can easily switch the power supply of each slot according to the slot that detects an abnormality.

[0037] (7) Based on the measuring device of (6), it can be formed as follows:

[0038] The measuring device further includes an abnormality detection unit that detects abnormality related to power supply to the modules connected to the slots in the slots based on information acquired from the plurality of power supply control units.

[0039] When an abnormality is detected in any one of the plurality of slots by the abnormality detection unit, the power supply management unit specifies all the slots connected to the modules connected to the slot in which the abnormality is detected as target slots.

[0040] In this way, the measuring device detects abnormalities using the abnormality detection unit that detects abnormalities related to power supply to the modules connected to the slots in the plurality of slots. Therefore, the measuring device can appropriately detect abnormalities in each slot and switch power supply.

[0041] (8) The measuring device according to any one of (1) to (7) may be configured as follows:

[0042] The measuring device further includes a plurality of module communication units, which are provided corresponding to the plurality of slots and communicate with the modules connected to the slots.

[0043] When abnormality information indicating an abnormality is received from the module communicating with the module communication unit using any of the multiple module communication units, the power management unit determines all the slots connected to the modules connected to the slot corresponding to the module communication unit as target slots.

[0044] In this way, the measurement device detects an abnormality based on the abnormality information received from the module, and thus can appropriately switch the power supply according to the abnormality on the module side.

[0045] According to the present invention, a measuring system,

[0046] (9) The measuring system comprises:

[0047] Modules; and

[0048] A measuring device, which can be connected to the module, wherein

[0049] The measuring device comprises:

[0050] a plurality of slots capable of connecting the modules;

[0051] a power management unit that controls supply of power to the modules connected to the plurality of slots; and

[0052] a display unit for displaying the measurement signal acquired by the module,

[0053] When the power management unit detects an abnormality in any one of the plurality of slots, the power management unit determines all the slots connected to the modules connected to the slot in which the abnormality is detected as target slots.

[0054] The supply of electric power to the identified target slot is stopped.

[0055] Thus, when an abnormality is detected in any one of the plurality of slots, the measuring system identifies all slots to which the module connected to the slot in which the abnormality is detected is connected, and stops the power supply to the slot. Therefore, according to the measuring system, the power supply to the modules connected to the slot in which the abnormality is detected can be stopped at the same time. Therefore, the measuring system can handle multi-slot width modules connected via a plurality of slots.

[0056] According to the present invention, a program,

[0057] (10) The program controls a measuring device, the measuring device having:

[0058] processor;

[0059] multiple slots, which can connect modules; and

[0060] A display unit displays measurement signals acquired by the modules connected to the plurality of slots, wherein:

[0061] The processor is caused to execute the following steps:

[0062] When an abnormality is detected in any one of the plurality of slots, all of the slots to which the modules connected to the slot in which the abnormality is detected are connected are determined as target slots; and

[0063] The supply of electric power to the identified target slot is stopped.

[0064] In this way, when the measuring device that performs operations based on the program detects an abnormality in any of the plurality of slots, it identifies all the slots to which the module connected to the slot in which the abnormality is detected is connected, and stops the power supply to the slot. Therefore, according to the measuring device, the power supply to the modules connected to the slot in which the abnormality is detected can be stopped at the same time. Therefore, the measuring device can handle multi-slot width modules connected via the plurality of slots.

[0074] <Comparative Example>

[0075] Figure 1 : This is a diagram showing the structure of a frame system 9 according to a comparative example. The frame system 9 has a frame controller 90 according to a comparative example and modules 94 (94a, 94b). The frame controller 90 according to the comparative example has a plurality of slots in which the modules 94 can be installed. The modules 94 provide the frame controller 90 with various information such as measured values. The module 94 has a connector for connecting to the frame controller 90. The user installs the module 94 in the slot and connects the connector of the module 94 to the frame controller 90.

[0076] The connector of the module 94 has a signal line for receiving power as a driving power source and an action control signal from the frame controller 90. The module 94 connected to the frame controller 90 performs actions corresponding to the type of the module 94, such as acquiring electrical signals representing measurement values ​​of various physical quantities based on the action control signal. The module 94 transmits information such as the measurement values ​​of the physical quantities acquired via the connector to the frame controller 90.

[0077] 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.

[0078] The power supply control unit 91 has a function of switching the supply of power as a driving power source to the module 94 installed in the corresponding slot. In addition, regarding the power supply as a driving power source to the module 94, the power supply control unit 91 has a function of acquiring information such as voltage and current.

[0079] The module communication unit 92 has the function of communicating with the module 94 to acquire information including the model name of the module 94 and controlling the operation of the module 94. The information sent and received between the module communication unit 92 and the module 94 also includes a signal for the frame controller 90 to recognize whether the module 94 is inserted or removed.

[0080] The abnormality detection unit 93 has a function of detecting abnormality of each slot based on information acquired by the power control unit 91. When abnormality in power supply to a slot is detected, the abnormality detection unit 93 can control the power control unit 91 of the slot to stop the power supply.

[0081] With the above structure, the power control unit 91 detects the slot where the module 94 is installed, and starts to supply power to the module 94 installed in the 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 always monitors each power control unit 91. When an abnormality is detected in the power control unit 91 of any slot, the abnormality detection unit 93 instructs the power control unit 91 of the slot to stop the power supply to the module 94.

[0082] Here, consider a situation where a multi-slot wide module is connected to the frame controller 90 involved in the comparative example. A multi-slot wide module is a module that occupies multiple slots. The multi-slot wide module may have multiple connectors and be connected to the frame controller 90 via multiple slots.

[0083] With respect to multi-slot width modules, there is an upper limit to the amount of current that flows through each connector. Therefore, in order to ensure the power supply capacity, it is considered to connect the power supplies of the frame controller 90 in parallel with respect to multiple connectors and implement power supply in parallel. With respect to such a multi-slot width module in which the power supplies are connected in parallel internally, if the timing of starting and ending the power supply differs according to the connector, the current will be concentrated on the connector to which the power supply stops lagging, and as a result, it is possible to damage the internal circuit. Therefore, with respect to starting and stopping the power supply to the multi-slot width module, from the perspective of preventing damage to the multi-slot width module, it is necessary to perform it simultaneously for all connectors.

[0084] However, in the case where a multi-slot width module is connected to the frame controller 90 involved in the comparative example, the power supply to multiple connectors cannot be stopped at the same time. Therefore, with respect to the frame controller 90 involved in the comparative example, it is considered to prohibit the parallel connection of the power supply. However, even in the case where the power supply is not connected in parallel inside the multi-slot width module, if the power supply to all connectors is not stopped at the same time, it may sometimes cause damage to the internal circuit. For example, in the case where a signal is sent to a circuit connected to a connector to which the power supply has been stopped in advance, the circuit may be damaged due to locking, etc. Therefore, with respect to the frame controller 90 involved in the comparative example, even if the parallel connection of the power supply is prohibited, there are design limitations from the viewpoint of preventing damage to the internal circuit.

[0085] Thus, the frame controller 90 according to the comparative example has room for improvement in terms of its handling of multi-slot width modules.

[0086] <Implementation Method>

[0087] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In each of the drawings, the same reference numerals are used for parts having the same structure or function. In the description of this embodiment, for the same parts, repeated descriptions may be appropriately omitted or simplified.

[0088] Figure 2 FIG. 1 is a diagram showing an example of the appearance of a frame controller 10 according to an embodiment. Figure 3 FIG. 1 is a diagram showing an example of the appearance of a module 20 according to an embodiment. Figure 4 1 is a block diagram showing a structural example of a frame system 1 according to an embodiment. Figure 4 As shown, a frame system 1 as a measurement system includes a frame controller 10 and modules 20 .

[0089] like Figure 2 As shown, the frame controller 10 as a measuring device includes a plurality of slots 17 , a display unit 18 , and an operation unit 19 .

[0090] The slot 17 is an insertion port for installing the module 20. The slot 17 can connect the module 20. The frame controller 10 may have a connector 25 (see FIG. 1 ) for connecting to the module 20 in the slot 17. Figure 3 )The connecting part of electrical connection and mechanical connection.

[0091] The display unit 18 is a monitor that displays information to the user. The display unit 18 displays, for example, the waveform of the signal acquired by the module 20. The display unit 18 can be, for example, a liquid crystal panel display or an organic EL (ElectroLuminescence) display. The display unit 18 can be configured as a touch screen (touch panel) that is integrally provided with the operation unit 19.

[0092] The operation unit 19 includes one or more input interfaces for accepting operations from the user. The operation unit 19 is, for example, a physical key, a capacitive key, a pointing device, or a touch screen integrated with the display unit 18, but is not limited thereto. At least one of the display unit 18 and the operation unit 19 may be integrated with the frame controller 10 or may be separately provided.

[0093] The module 20 provides information such as measurement values ​​to the frame controller 10. The module 20 may be, for example, a variable wavelength 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 measurement values ​​such as voltage, current, and power, and measurement values ​​related to physical quantities other than light such as temperature, pressure, flow, strain, acceleration, pH, or humidity.

[0094] like Figure 3 As shown, the module 20 has 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. The user connects the connector 25 of the module 20 to the frame controller 10 by installing the module 20 in the slot 17.

[0095] The connector 25 of the module 20 has a signal line for receiving power as a driving power source and an action control signal from the frame controller 10. The module 20 connected to the frame controller 10 obtains an electrical signal representing the measured values ​​of various physical quantities based on the action control signal. The module 20 sends the measured values ​​of the physical quantities obtained via the connector 25 to the frame controller 10. The frame controller 10 displays the waveform of the measured values ​​of the physical quantities provided from the module 20 on the display unit 18.

[0096] also, Figure 3The module 20 shown in the example occupies one slot 17 when connected to the frame controller 10, but the module 20 may occupy multiple slots 17 and be connected to the frame controller 10. As mentioned above, a module 20 in which one module 20 occupies multiple slots 17 is called a "multi-slot width module". The multi-slot width module may have multiple connectors 25 and be connected to the frame controller 10 via multiple slots 17. When connected to the frame controller 10, the number of slots 17 occupied by the multi-slot width module may not be the same as the number of connectors 25 that the multi-slot width module has. For example, a multi-slot width module occupies a slot 17, but may have a portion that does not have a connector 25 corresponding to the slot 17.

[0097] Figure 4 The example shows two modules 20 (20a, 20b) connected to the frame controller 10. The module 20a has a shape that occupies one slot 17 and has one connector 25. The module 20b has a shape that occupies two slots 17 and has two connectors 25. The module 20b corresponds to a multi-slot width module.

[0098] like Figure 4 As shown, as the internal structure of the device, the frame controller 10 has a power control unit 11 (11a, 11b, 11c), a module communication unit 12 (12a, 12b, 12c), an abnormality detection unit 13, a power management unit 14, a table storage 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. Figure 4 In the example of FIG. 2 , the module 20a is connected to the power supply control unit 11a and the module communication unit 12a via the connector 25. The module 20b is connected to the power supply control units 11b and 11c and the module communication units 12b and 12c via the connector 25.

[0099] The power control unit 11 has a function of switching 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. In addition, the power control unit 11 has a function of acquiring information such as voltage and current regarding the power supply as a driving power source to the module 20.

[0100] The module communication unit 12 has the 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 sent and received between the module communication unit 12 and the module 20 also includes a signal for the frame controller 10 to recognize the insertion and removal of the module 20. The module communication unit 12 has the function of notifying the power management unit 14 of the model name acquired from the module 20.

[0101] The abnormality detection unit 13 has a function of detecting abnormalities in each slot 17 based on the 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 where the abnormality is detected, and the type of abnormality. The type of abnormality may include, for example, the power supply current, voltage, power, user operation abnormality, and input / output abnormality of the module 20.

[0102] The table storage unit 15 as a storage unit stores a power control table. The power control table is information indicating the slot 17 to which the module 20 is connected using the connector 25 for each module 20 connected to the frame controller 10. For an example of the power control table, refer to Figure 6 Give a narrative.

[0103] The storage unit 16 stores the connector information. The connector information is information indicating the correspondence between the model name of the module 20, the slot width of the slot 17 occupied by the module 20 identified by the model name, and the configuration of the slot 17 connected by the connector 25 for the slot width. The slot width is the number of slots 17 occupied by the module 20. For example, Figure 4 The slot width of module 20a is 1. The slot width of module 20b is 2. For example, if connection based on connector 25 is represented as "1" and non-connection is represented as "0", the configuration of slot 17 connected by connector 25 of module 20a can be represented as [1]. The configuration of slot 17 connected by connector 25 of module 20b can be represented as

[11] .

[0104] like Figure 4 As shown, the module 20 (20a, 20b) has a storage unit 21 (21a, 21b). The storage unit 21 of the module 20 stores connector information about 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 configuration of the slot 17 connected by the connector 25 for the slot width. The frame controller 10 obtains the connector information from the module 20 in accordance with the connection with the module 20. When the obtained connector information is not stored in the storage unit 16, the frame controller 10 causes the storage unit 16 to additionally store the connector information.

[0105] The power management unit 14 has a function of managing the operation of the power control unit 11 (11a, 11b, 11c) of each slot 17. Specifically, the power management unit 14 creates a power control table according to the model name information of the module 20 obtained through the module communication unit 12 and the connector information stored in the storage unit 16, and stores it in the table storage unit 15.

[0106] 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 the slots 17 used by the modules 20 connected to the slot 17 in which the abnormality is detected. The power management unit 14 controls the power control unit 11 corresponding to each of the identified slots 17 to stop the power supply from the power control unit 11. Therefore, when a multi-slot wide module is connected, the frame controller 10 according to the present embodiment can simultaneously stop the power supply to the plurality of connectors 25 of the multi-slot wide module. Therefore, the frame controller 10 can handle the multi-slot wide module.

[0107] Furthermore, in this embodiment, Figure 4 Each structural element shown as a module in the embodiment is implemented by different hardware, but it is not limited to this structure. For example, more than or equal to 2 structural elements can be implemented by common hardware. Specifically, for example, the table storage unit 15 and the storage unit 16 can be composed of the same memory. In addition, Figure 4 At least a portion of the various structural elements shown can be implemented by executing a program on a general-purpose processor. Figure 4 At least a part of each of the structural elements shown can be implemented by software. For example, the abnormality detection unit 13 and the power management unit 14 can be implemented by software. In addition, the frame controller 10 and the module 20 can be implemented by a single device or by the coordinated operation of multiple devices.

[0108] Figure 5 2 is a flowchart showing an example of the operation of the frame controller 10 according to one embodiment. Figure 5 The operation of the frame controller 10 described above may correspond to one of the control methods of the frame controller 10 . Figure 5 The actions of each step can be performed based on the control of the power management unit 14 of the frame controller 10. Figure 5 Actions such as Figure 4 The description will be given below an example in which the process starts with two modules 20 ( 20 a , 20 b ) connected to the slots 17 of the frame controller 10 .

[0109] In step S1, the power management unit 14 starts supplying power to each module 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 the module 20a. The power management unit 14 controls the power control units 11b and 11c to start supplying power to the module 20b.

[0110] In step S2, the power management unit 14 obtains the model name of each module 20 connected to the frame controller 10. Specifically, the power management unit 14 controls the module communication units 12a, 12b, and 12c to obtain the model name of the modules 20a and 20b from the modules 20. The power management unit 14 refers to the storage unit 16 and determines whether the 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.

[0111] In step S3, the power management unit 14 creates a power control table based on the model name identified 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 of each module 20 connected to the frame controller 10 and the configuration of the slot 17 connected using the connector 25. The power management unit 14 creates the power control table based on the acquired slot width and the configuration of the connected slot 17.

[0112] Figure 6 1 is a diagram showing an example of an installation of the module 20 and an example of the power supply control table 100. Figure 6 In the example of FIG. 1 , the frame controller 10 has nine slots 17. The nine slots 17 are identified by slot numbers (Slot No.) "1" to "9". Figure 6In the example, 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 slot 17 with slot numbers "1" to "3". The configuration of slot 17 connected by connectors 25c1 and 25c2 of module 20c can be expressed as

[101] . The slot width of module 20d is 2. Module 20d occupies slot 17 with slot numbers "4" and "5". The configuration of slot 17 connected by connectors 25d1 and 25d2 of 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 configuration of slot 17 connected by connector 25e of module 20e can be expressed as [1]. The slot width of module 20f is 3. Module 20f occupies slot 17 with slot numbers "7" to "9". The configuration of the slot 17 connected by the connectors 25f1, 25f2 of the module 20f can be expressed as

[011] .

[0113] exist Figure 6 In the power control table 100, regarding MODULE_ID[n], the connection status of all slots 17 connected to the connector 25 of the module 20 occupying the slot 17 of slot number "n" is represented by a digit "1", and the connection status of the other slots 17 is represented by a digit "0". Here, n is a natural number (n: 1, 2, ...).

[0114] For example, slot 17 of slot numbers "1" to "3" is occupied by module 20c. Connectors 25c1 and 25c2 of module 20c are connected to slots 17 of slot numbers "1" and "3". Figure 6As shown, MODULE_ID[1] to MODULE_ID[3] are all [000000101]. Here, the lower 3 bits of MODULE_ID[1] to MODULE_ID[3] are the same as the configuration

[101] of slot 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]. The slots 17 with slot numbers "7" to "9" are occupied by the module 20f. The connectors 25f1 and 25f2 of the module 20f are connected to the slots 17 with slot numbers "8" and "9". Therefore, MODULE_ID[7] to MODULE_ID[9] are all [110000000].

[0115] Furthermore, the power management section 14 may create a power control table based on the connector information acquired from the module 20 via the module communication section 12 .

[0116] Back to Figure 5 In step S4, the power management unit 14 determines whether the abnormality detection unit 13 detects an abnormality in any of the slots 17. Specifically, the power management unit 14 may determine that an abnormality is detected when receiving abnormality information from the abnormality detection unit 13. The power management unit 14 proceeds to step S5 when an abnormality is detected (YES in step S4), and waits as it is otherwise (NO in step S4).

[0117] In step S5, the power management unit 14 determines all slots 17 connected to the connector 25 of the module 20 connected to the slot 17 in which the abnormality is detected as target slots. The target slot is the slot 17 to which the power should be cut off. Specifically, the power management unit 14 determines the slot number of the slot 17 in which the abnormality is detected by referring to the abnormality information received from the abnormality detection unit 13 in step S4. The power management unit 14 determines all slots 17 connected to the connector 25 of the module 20 connected to the slot 17 with the determined slot number by referring to the power control table.

[0118] For example, in the power control table, Figure 6In the case where the abnormality detection unit 13 detects an abnormality, the slot number of the slot 17 is set to "3". In this case, the power management unit 14 refers to MODULE_ID[3] indicating the connection relationship of the slot 17 with the slot number "3". MODULE_ID[3] = [000000101], so the power management unit 14 determines the slots 17 with the slot numbers "1" and "3" as the target slots.

[0119] In step S6, the power management unit 14 controls the power control units 11 corresponding to the target slots so that the power supply to all the target slots determined in step S5 is stopped at the same time. As a result, the power supply to all the connectors 25 connected to the slot 17 where the abnormality has occurred is stopped at the same time. When the processing of step S6 is completed, the power management unit 14 ends the operation by Figure 5 A flowchart representing the process.

[0120] As described above, the frame controller 90 involved in the comparative example can only cut off the power supply of the slot where the abnormality is detected. In contrast, the frame controller 10 as the measuring device involved in this embodiment, when any of the plurality of slots 17 detects an abnormality, determines all the slots 17 connected to the modules 20 connected to the slot 17 where the abnormality is detected as the target slots. The frame controller 10 stops the power supply to the target slots. Therefore, according to the frame controller 10, the power supply to the modules 20 connected to the slots 17 where the abnormality is detected can be stopped at the same time.

[0121] In addition, the frame controller 10 uses the power control table to determine the slots 17 to which the power supply is stopped at the same time. Therefore, according to the frame controller 10, it is possible to appropriately cut off the power supply without depending on the combination of the types of modules 20, the position of the slot 17 where the module 20 is installed, and the position of the slot 17 where the abnormality occurs. In addition, with respect to the frame controller 10, the power management unit 14 uniformly manages the actions of each power control unit 11. Therefore, even if an abnormality occurs simultaneously in multiple slots 17 connected to the multi-slot width module, for example, an abnormal action of double power cutoff can be prevented. Furthermore, according to the frame controller 10, even if an abnormality occurs simultaneously in multiple different modules 20, the above-mentioned power can be cut off at the same time.

[0122] Thus, according to the frame controller 10, for a multi-slot width module, the power supplies from the connectors 25 can be connected in parallel inside the module 20, and the load current capacity in one module 20 can be increased. In addition, according to the frame controller 10, even when the power supplies are not connected in parallel, when there is communication and control signal connection between the slots 17 in the module 20, the risk of failure can be reduced.

[0123] About reference Figure 4 In the rack system 1 described above, the rack controller 10 has the abnormality detection unit 13, but the module side may also have an abnormality detection unit. Figure 7 Next, Figure 4 The same reference numerals are used for common structures, and detailed description thereof will be omitted.

[0124] Figure 7 2 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). Figure 7 As shown, as the internal structure of the device, the frame controller 30 has a power control unit 11 (11a, 11b), a module communication unit 12 (12a, 12b), a power management unit 14, a table storage unit 15 and a storage unit 16. The module 40 (40a, 40b) has a storage unit 41 (41a, 41b) and an abnormality detection unit 42 (42a, 42b).

[0125] exist Figure 7 In the structural example, the frame controller 30 does not have an abnormality detection unit. The abnormality detection unit 42 of the module 40 detects abnormalities in the module 40. If 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 where the abnormality is detected and the type of abnormality. The type of abnormality includes, for example, the internal temperature of the module 40, the internal air pressure of the module 40, the internal FAN alarm of the module 40, the user's operation abnormality on the module 40, the vibration or impact abnormality of the module 40, and the humidity abnormality (condensation) inside the module 40 in addition to the power supply current, voltage, power, user operation abnormality, and input / output abnormality of the module 20.

[0126] With this structure, the power management unit 14 detects an abnormality based on the abnormality information received from the module 40. Therefore, the frame controller 30 can appropriately switch the power supply according to the abnormality on the module 40 side. In addition, it can be formed in the following manner, that is, both the frame controllers 10 and 30 and the modules 20 and 40 have an abnormality detection unit, and the power management unit 14 switches the power supply according to the abnormality detected by any of these abnormality detection units.

[0127] The present invention is not limited to the above-mentioned embodiments. For example, multiple modules recorded in the block diagram may be integrated, or one module may be divided. Multiple steps recorded in the flowchart may be executed in parallel or in a different order according to the processing capacity of the device executing each step, or as needed, instead of being executed in a time series according to the description.
