  As a technique for dealing with such a problem, a technique for managing a wiring path using an identification code such as a barcode is known (for example, see Patent Document 1). In this related technique, an identification code is pasted to the connector of the wiring cable and the accommodation destination of the connector. In this related technique, each identification code is read by a reading device such as a bar code reader and the corresponding relationship is output.

  Further, as another technique for dealing with such a problem, a technique for managing a wiring path using identification information of a power supply module is known (for example, see Patent Document 2). In this related technology, identification information of a power supply module to be connected to a power supply device via a power cable is stored in advance. This related technology acquires the identification information of the power supply module connected to the power supply device, and informs that an erroneous connection has occurred when the acquired identification information does not correspond to the stored identification information. To do.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  A configuration of a power supply path verification system 1 as an embodiment of the present invention is shown in FIG. In FIG. 1, a power path verification system 1 includes a power path verification device 10 and one or more power connection detection devices 20. In FIG. 1, a figure surrounded by a solid line is a device constituting the power supply path verification system 1 according to the present embodiment, and a figure surrounded by an alternate long and short dash line is a power supply path verification as the present embodiment. The system 1 is an example of a system to be verified. The power path verification device 10 and each power connection detection device 20 are communicably connected to each other via a network constituted by the Internet, a LAN (Local Area Network), a public line network, a wireless communication network, or a combination thereof. Yes. FIG. 1 shows four power connection detection devices 20, but the number of power connection detection devices included in the power path verification system of the present invention is not limited.

  In FIG. 1, the power supply path verification system 1 determines whether or not each power cable 91 of one or more devices 90 is correctly connected to any one of n (n is an integer of 1 or more) power supply systems 80. Verify that.

  The power supply system 80 is a unit in which power is supplied and cut off. For example, each of the n power supply systems 80 is supplied with power when a switch is turned on in each of n breakers connected to a power supply source, and is shut off when turned off. . In FIG. 1, two power supply systems 80 are shown, but the number of power supply systems that can supply power to a system to be verified by the power supply path verification system of the present invention is not limited.

  The device 90 includes one or more power reception units 92 and operates when power is supplied from the power supply system 80 to the power reception unit 92 via the power cable 91. If the device 90 has a plurality of power receiving units 92 and each power cable 91 is wired so as to be able to receive power from different power supply systems 80, even if a failure or power failure occurs in one power supply system 80, The power can be received from the power supply system 80 and the operation can be continued. FIG. 1 shows two devices 90 each having two power receiving units 92. However, the number of devices included in the system to be verified by the power path verification system of the present invention and the number of power receiving units. The number is not limited.

  The power cable 91 is a cable that can supply power to the power receiving unit 92 by connecting the power receiving unit 92 and the power supply system 80 included in the device 90.

  Each power connection detection device 20 can be attached to each power cable 91. For example, the power connection detection device 20 is configured to include a current measuring device that measures a current value by surrounding the power cable 91 with a sensor that detects a change in strength of a magnetic field generated by a current flowing in the power cable 91. Also good. In this case, the power connection detection device 20 is attached so as to surround the power cable 91 at the sensor portion of the current measuring device. For example, an overhead wire ammeter (clamp meter) is well known as such a current measuring device. The clamp meter measures a current value flowing through an electric wire passing through a ring of a sensor (clamp) configured in a ring shape. In this case, the power connection detection device 20 is attached so that the target power cable 91 is passed through the ring of the clamp. Various known techniques can be applied to the current detection technique for realizing the clamp meter and the technique for fixing the clamp meter to the power cable 91 so that the current can be measured. The power cable 91 may include a plurality of electric wires such as a 2-core or 3-core. At this time, a general clamp meter may not be able to measure the current flowing through the plurality of electric wires. In that case, the power connection detection device 20 may be attached to an attachment (not shown) that separates the electric path by being attached to the power cable 91.

  Further, in each power connection detection device 20, a corresponding power system 80 is predetermined by power system definition information described later. Each power connection detection device 20 is attached to a power cable 91 connected to a power receiving unit 92 that is determined to be supplied with power from the corresponding power system 80. In the present embodiment, it is assumed that which power supply system 80 is supplied with power to each power receiving unit 92 is determined in advance as a power supply path design. For example, the power connection detection device 20 may be able to visually recognize information representing the power system 80 corresponding to the power connection detection device 20 from the outside. Specifically, each power connection detection device 20 may have a label on which a character string representing the corresponding power supply system 80 is written. In this case, the administrator supplies the power connection detection device in which each power cable 91 is labeled with the power system 80 determined to supply power to the power receiving unit 92 to which the power cable 91 is connected in accordance with the power path design. 20 may be attached.

  Next, FIG. 2 shows a functional block configuration of each device constituting the power supply path verification system 1.

  In FIG. 2, the power supply path verification device 10 includes a power supply system definition information storage unit 11, a power supply system identification unit 12, a status information reception unit 13, and a power supply path verification information output unit 14. Here, the power supply path verification device 10 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a storage device such as a hard disk, a network interface, and a display such as a liquid crystal display. And a computer device provided with the device. In this case, the power system definition information storage unit 11 is configured by a storage device. The power system identification unit 12 and the status information receiving unit 13 are configured by a network interface and a CPU that reads a computer program and various data stored in the ROM and the storage device into the RAM and executes them. The power supply path verification information output unit 14 includes a display device and a CPU that reads and executes a computer program and various data stored in the ROM and the storage device in the RAM. Note that the hardware configuration of the power supply path verification device 10 and each functional block thereof is not limited to the above-described configuration.

  The power system definition information storage unit 11 stores the identification information of the power connection detection device 20 and the identification information of the power system 80 in association with each other.

  The power system identification unit 12 acquires identification information of the power system 80 for which power supply has been started. For example, when the above-described breaker has a function of outputting the on / off state, the power supply system identification unit 12 is connected to such a breaker so as to be able to communicate with the power supply that has changed from the off state to the on state. The identification information of the system 80 can be acquired. Specifically, the power system identification unit 12 may receive the identification information of the power system 80 transmitted from the breaker according to the change from the off state to the on state. Alternatively, the power system identification unit 12 stores the identification information of the power system 80 corresponding to each breaker in advance, so that the breaker that is the source of the on information transmitted in response to the change from the off state to the on state The identification information of the power supply system 80 stored in association with may be acquired. Alternatively, the power system identification unit 12 may acquire identification information of the power system 80 for which power supply has been started, via the input device.

  The status information receiving unit 13 receives status information transmitted from the power connection detection device 20. Here, the status information is information including identification information of the power connection detection device 20 attached to the power cable 91 where current has started to flow. The status information receiving unit 13 receives status information from the power connection detection device 20 that has detected the current flowing through the target power cable 91 in response to the start of power supply in an arbitrary power system 80.

  The power path verification information output unit 14 indicates whether or not the identification information of the power connection detection device 20 included in the received status information is associated with the identification information of the power system 80 from which power supply is started. The route verification information is output by referring to the power system definition information storage unit 11. If the identification information of the power connection detection device 20 included in the status information is not associated with the identification information of the power supply system 80 for which power supply has been started, the power connection detection device 20 is attached. Therefore, the connection of the power cable 91 does not conform to the power path design. Further, when the identification information of the power connection detection device 20 included in the status information is associated with the identification information of the power supply system 80 from which power supply is started, the power connection detection device 20 is attached. The connection of the power cable 91 follows the power path design. For example, the power path verification information output unit 14 may include the identification information of the power connection detection device 20 that does not comply with the power path design in the power path verification information so as to notify an inappropriate connection.

  In FIG. 2, the power connection detection device 20 includes a current detection unit 21, an identification information storage unit 22, and a status information transmission unit 23. Here, the power connection detection device 20 can be configured by a microcomputer including a CPU and a memory, a current measuring device such as a clamp meter, and a network interface such as a wireless communication module. In this case, the current detection unit 21 includes a current measuring device and a CPU that reads and executes a computer program and various data stored in a memory. The identification information storage unit 22 is configured by a memory. The status information transmission unit 23 includes a network interface and a CPU that reads and executes computer programs and various data stored in the memory.

  The current detection unit 21 detects a current flowing through the power cable 91.

  The identification information storage unit 22 stores identification information of the device itself.

  The status information transmission unit 23 transmits status information including identification information to the power path verification device 10 when the current flowing through the power cable 91 is detected by the current detection unit 21. Here, the status information transmission unit 23 may detect the change from the state in which no current is flowing through the power cable 91 to the state in which the current is flowing, and transmit the status information in response to the detection of the change. For example, the current detection unit 21 may transmit the status information at a timing when the current value measured by the clamp meter exceeds a threshold value.

  The operation of the power supply path verification system 1 configured as described above will be described with reference to FIG. In FIG. 3, the left diagram shows the operation of the power connection detection device 20, the right diagram shows the operation of the power supply path verification device 10, and the dashed arrows connecting the left and right indicate the flow of data. In addition, the power supply path verification system 1 starts the following operation when power supply to a certain power supply system 80 is started.

  First, the power system identification unit 12 of the power path verification device 10 acquires identification information of the power system 80 for which power supply has been started (step S1).

  Next, the current detection unit 21 of the power connection detection device 20 detects that current has started flowing (step S2). Here, the power connection detection device 20 that detects that a current has started flowing out is the power connection detection device 20 attached to each power cable 91 that is connected to the power supply system 80 from which power supply has been started.

  Next, the status information transmission unit 23 of the power connection detection device 20 that has detected that a current has started flowing in step S2 transmits status information including identification information of the device itself to the power supply path verification device 10 (step S3). .

  Next, the status information receiving unit 13 of the power path verification device 10 receives the status information from each power connection detection device 20 that has transmitted the status information in step S3 (step S4).

  Next, the power path verification information output unit 14 associates the identification information of the power connection detection device 20 included in each status information received in step S4 with the identification information of the power system 80 acquired in step S1. It is determined by referring to the power system definition information storage unit 11 (step S5).

  Here, when the identification information of the power connection detection device 20 included in all the status information received in step S4 is associated with the identification information of the power system 80 acquired in step S1, the power path verification information The output unit 14 outputs power supply path verification information indicating appropriate power supply connection (step S6).

  On the other hand, among the status information received in step S4, there is one in which the identification information of the power connection detection device 20 included in the status information is not associated with the identification information of the power system 80 acquired in step S1. In this case, the power supply path verification information output unit 14 outputs power supply path verification information indicating that an inappropriate power supply connection is made (step S7).

  Thus, the power supply path verification system 1 ends the operation.

  The power supply path verification system 1 sequentially performs the above operations for each power supply system 80.

  Next, a specific operation example of the embodiment of the present invention will be described with reference to FIG. In FIG. 4, the power supply path verification system 1 verifies the wiring paths for the four power supply systems 80 </ b> A to 80 </ b> D with respect to the power supply cable 91 included in the computer apparatuses 901 a to 901 d and the outlet boxes 902 a to 902 d. Hereinafter, the computer apparatuses 901a to 901d are also collectively referred to as a computer apparatus 901. The outlet boxes 902a to 902d are also collectively referred to as outlet boxes 902. The power supply systems 80A to 80D are also collectively referred to as the power supply system 80. The computer device 901 and the outlet box 902 correspond to the device 90 in the present embodiment.

  In FIG. 4, breakers 70a to 70d (hereinafter also collectively referred to as breaker 70) cut off (off) or release (on) the power supplied from a power supply source (not shown) such as a commercial power source. ) To supply power as power supply systems 80A to 80D, respectively.

  Each outlet box 902 includes a power receiving unit (not shown) and one or more outlets. The outlet boxes 902a to 902d are connected to the breakers 70a to 70d via power cables 91e to 91h, respectively. Further, the outlet of each outlet box 902 is detachable from the plug of the power cable 91 of another device 90. When the breaker 70 connected to the outlet box 902 is turned on, the power supplied from the breaker 70 to the power receiving unit is supplied to the device 90 ahead through the power cable 91 connected to each outlet. Supply.

  Further, each of the computer devices 901 has two power receiving units 92 and is connected to two power cables 91. For example, the computer device 901a includes power receiving units 92a1 and 92a2, and is connected to power cables 91a1 and 91a2. The same applies to the other computer devices 901b to 901d.

  In this example, the power supply path design is defined as shown in FIG. For example, in the first and second lines of FIG. 5, the power receiving unit 92a1 of the computer apparatus 901a is determined to receive power from the power supply system 80A, and the power receiving unit 92a2 is determined to receive power supply from the power supply system 80B. It represents that.

  In FIG. 4, twelve power connection detection devices 20 are attached to each power cable 91 according to the power path design shown in FIG. 5. The twelve power supply connection detection devices 20 are assumed to store any one of A0 to A2, B0 to B2, C0 to C2, and D0 to D2 in the identification information storage unit 22 as identification information. In FIG. 4, a character string written inside a graphic representing the power connection detection device 20 indicates identification information of the power connection detection device 20. Hereinafter, the power connection detection device 20 whose identification information is XX is also referred to as a power connection detection device 20 (XX).

  Further, in this example, information as shown in FIG. 6 is stored in the power system definition information storage unit 11 of the power path verification device 10. For example, the first line in FIG. 6 indicates that the identification information “A0” of the power connection detection device 20 is associated with the identification information “A” of the power supply system 80. For example, when the power connection detection device 20 is provided with a label or the like on which the identification information of the corresponding power supply system 80 is printed, the administrator follows each power supply path design of FIG. 5 as shown in FIG. The corresponding power connection detection device 20 can be attached to the power cable 91.

  At this time, the operation of the power supply path verification system 1 when the breaker 70a is turned on will be described.

  First, the power supply system identification unit 12 of the power supply path verification device 10 acquires the identification information “A” of the power supply system 80A in which power supply is started when the breaker 70a is turned on (step S1).

  At this time, since power supply to the power supply system 80A is started, a current flows through the power supply cables 91e, 91a1, and 91b1.

  Therefore, the power connection detection devices 20 (A0), 20 (A1), and 20 (A2) attached to the power cables 91e, 91a1, and 91b1, respectively, detect currents by the current detection unit 21 (step S2).

  Then, the status information transmission unit 23 of the power connection detection devices 20 (A0), 20 (A1), and 20 (A2) transmits status information including identification information of the own device to the power supply path verification device 10. (Step S3).

  Next, the status information receiving unit 13 of the power path verification device 10 receives the status information transmitted from the power connection detection devices 20 (A0), 20 (A1), and 20 (A2), respectively (step S4).

  Next, the power supply path verification information output unit 14 of the power supply path verification apparatus 10 refers to the power supply system definition information in FIG. 6, thereby identifying the identification information of the power connection detection apparatus 20 included in each of the received three status information. It is determined that “A0”, “A1”, and “A2” are associated with the identification information “A” of the power supply system 80 acquired by the power supply system identification unit 12 (Yes in step S5).

  Therefore, the power path verification information output unit 14 outputs power path verification information indicating that the power path for the power system 80A is appropriate (step S6).

  The power path verification system 1 executes the above operation every time the breakers 70b to 70d are sequentially turned on.

  Next, in the same case, consider the case where the power cable 91 of each computer apparatus 901 is wired as shown in FIG. The power supply path design and the power supply system definition information are assumed to be the same as those shown in FIGS.

  In this case, first, the operation of the power supply path verification system 1 when the breaker 70a is turned on will be described.

  Here, first, the power supply system identification unit 12 of the power supply path verification device 10 acquires the identification information “A” of the power supply system 80A in which power supply is started when the breaker 70a is turned on (step S1).

  At this time, since power supply to the power supply system 80A is started, a current flows through the power supply cables 91e, 91a1, and 91a2.

  Therefore, the power connection detection devices 20 (A0), 20 (A1), and 20 (B1) attached to the power cables 91e, 91a1, and 91a2, respectively, detect currents by the current detection unit 21 (step S2).

  Then, the status information transmission unit 23 of the power connection detection devices 20 (A0), 20 (A1), and 20 (B1) transmits status information including identification information of the device itself to the power supply path verification device 10. (Step S3).

  Next, the status information receiving unit 13 of the power path verification device 10 receives the status information transmitted from the power connection detection devices 20 (A0), 20 (A1), and 20 (B1), respectively (step S4).

  Next, the power supply path verification information output unit 14 of the power supply path verification apparatus 10 refers to the power supply system definition information in FIG. 6, thereby identifying the identification information of the power connection detection apparatus 20 included in each of the received three status information. Among them, “B1” is determined not to be associated with the identification information “A” of the power supply system 80 for which power supply has been started (No in step S5).

  Therefore, the power path verification information output unit 14 outputs power path verification information indicating that the wiring of the power cable 91a2 to which the power connection detection device 20 (B1) is attached is not appropriate as the power path for the power system 80A ( Step S7).

  Next, when the breaker 70b is turned on, the power supply path verification system 1 operates in substantially the same manner, and outputs power supply path verification information indicating that the power supply path for the power supply system 80B is appropriate.

  Next, when the breaker 70c is turned on, the power supply path verification system 1 operates in substantially the same manner, indicating that the wiring of the power supply cable 91b1 to which the power connection detection device 20 (A2) is attached is not appropriate. Outputs power path verification information.

  Next, when the breaker 70d is turned on, the power supply path verification system 1 operates in substantially the same manner, and outputs power supply path verification information indicating that the power supply path for the power supply system 80D is appropriate.

  Above, description of operation | movement of the specific example of this Embodiment is complete | finished.

  Next, effects of the embodiment of the present invention will be described. The power supply path verification system according to the embodiment of the present invention can more easily verify whether or not the power supply cable wiring path conforms to the power supply wiring design.

  The reason is that the power path verification device stores the correspondence between the power system identification information and the power connection detection device identification information in the power system definition information storage unit, and the power system identification unit supplies power. The identification information of the started power supply system is acquired, and when the power connection detection device detects the current of the power cable from which the current has flowed by the start of power supply by the current detection unit, the status information including the identification information of the own device is displayed This is because the transmission unit transmits the power to the power path verification device. Whether or not the power path verification device associates the identification information of the power connection detection device included in the status information received by the status reception unit with the identification information of the power system acquired by the power system identification unit. This is because the power supply path verification information indicating that is output.

  As a result, the administrator attaches the power connection detection device associated with the power supply system determined as the connection destination of each power cable to the power cable of each device according to the power supply path design. It is possible to verify whether or not the power supply path conforms to the power supply path design simply by performing an operation for starting power supply. In addition, even when the power supply path design is updated due to new installation or disposal of the device, the administrator only needs to newly install the power connection detection device or change the installation destination. There is no need to rebuild. Further, it is not necessary to newly prepare or replace a management barcode or the like to be attached to the power cable. Therefore, this embodiment further reduces the troublesome work of the administrator in verifying the power supply path.

  In the embodiment of the present invention, the power path verification device has been described mainly with respect to an example in which a current flowing through the power cable is detected using a clamp meter. In addition, the power supply path verification apparatus according to the present embodiment may be realized by other known techniques that can detect whether or not a current flows without cutting the power supply cable to be measured.

  In the embodiment of the present invention, the status information transmission unit of the power path verification device has been described mainly with respect to an example in which the status information is transmitted at the timing when the current value detected by the current detection unit exceeds the threshold value. In addition, the status information transmission unit uses other technology that can detect that the current has not flowed through the power cable to which the device is attached and that the current has flowed. Status information may be transmitted.

  In the above-described embodiment of the present invention, the operations of the power path verification device and the power connection detection device described with reference to the flowcharts are stored in the storage device (storage medium) of the computer device as the computer program of the present invention.
