Description

The present invention relates to a determination device and a determination method.

Generally, in places such as factories and other facilities where many electrical devices are installed, large amounts of wiring and electric wires (hereinafter simply referred to as wires) made of conductors covered with insulators are used due to the need to drive and control each piece of electrical device.

In such factories, for example, when performing work such as removing each wire, workers need to identify the wire to be removed from among the large number of wires. Specifically, workers identify the wire to be removed from among the large number of wires by checking the identification information printed on a part of each wire (for example, the end of each wire) (see Patent Documents 1 and 2).

Japanese Patent Application Laid-Open No. 9-301642 JP 2018-064455 A

Here, for example, the middle portion of each of the above-mentioned wires may be installed inside a pit or inside the premises. Therefore, when many wires are installed in a dense state, workers cannot easily confirm whether the entrance side wire visible at the entrance side of the pit, etc. and the exit side wire visible at the exit side of the pit, etc. are the wires to be worked on. In particular, when the wire to be worked on is a long wire (e.g., a wire of several tens of meters), it becomes more difficult to confirm whether the entrance side wire and the exit side wire are the same wire. This confirmation also becomes difficult when each wire crosses over other wires inside the pit, etc.

As such, the worker may not be able to easily identify the wire being worked on (identify the overall picture of the wire being worked on).

The present invention aims to provide a determination device and a determination method that make it easy to identify the wire being worked on.

To achieve the above object, the determination device of the present invention includes a processor that references a memory that stores multiple identifiers printed on the outer surfaces of multiple linear members in association with the linear members, and a communication device that communicates with a terminal device, and the processor determines whether the first identifier and the second identifier are printed on the same linear member based on a first identifier printed on the outer surface of the linear member and a second identifier printed on the outer surface of the linear member that are received from the terminal device via the communication device, and the multiple identifiers stored in the memory.

The determination device and method of the present invention make it easy to identify the wire being worked on.

Below, an embodiment of the present invention will be described with reference to the drawings. However, such an embodiment does not limit the technical scope of the present invention.

First, an example of the schematic configuration of the information processing system 10 in the first embodiment will be described. Figures 1 and 2 are diagrams illustrating the schematic configuration of the information processing system 10 in the first embodiment.

In the example shown in FIG. 1, the information processing system 10 includes a determination device 1, a terminal device 3, and a printing device 4. Note that the determination device 1 does not have to be a dedicated device, and may be an information processing device capable of executing other applications. In the following explanation, the determination device 1 is described as an information processing device 1. The information processing device 1 is, for example, a PC (Personal Computer) or a server.

The printing device 4 is a device used by an operator when installing each wire 7 (hereinafter also referred to as linear member 7), and is a device that prints, for example, identification information (hereinafter also referred to as identifier) that identifies each wire 7 on the outer surface of each wire 7. Specifically, the printing device 4 prints, for example, the identification information at equal intervals on the outer surface of each wire 7.

The printing device 4 may, for example, print identification information on each wire 7 before the wire 7 is cut off from the drum (not shown). The printing device 4 may also, for example, print identification information on a plate or the like attached to each wire 7.

The terminal device 3 is a device used by a worker to identify the wire 7 to be worked on from among the installed wires 7, and is, for example, a device that reads identification information printed on the outer surface of the wire 7. Specifically, as shown in FIG. 1, the terminal device 3 reads, for example, identification information printed on the outer surface of each wire 7 connecting the switchboard 5a and the switchboard 5b. The terminal device 3 then transmits the read identification information to the information processing device 1. The terminal device 3 may be, for example, a smartphone or a tablet terminal.

The information processing device 1 acquires related information about the wire 7 whose identification information has been read by the terminal device 3, based on the identification information transmitted from the terminal device 3 and the management information 201 stored in the storage device 2. The management information 201 is, for example, information that associates the identification information printed on the outer surface of each wire 7 with related information about each wire 7 (for example, information such as the manufacturing date and manufacturer of the wire 7). Then, the information processing device 1 transmits, for example, the identified related information to the terminal device 3.

This allows the worker to view related information about the wires 7 whose identification information has been read by the terminal device 3, enabling the worker to proceed with work such as removing each wire 7.

Note that, in the following description, it is assumed that the management information 201 is stored in a storage device 2 provided outside the information processing device 1, but the management information 201 may also be stored in a storage area (not shown) provided inside the information processing device 1.

In the example shown in FIG. 1, the middle portion of each wire 7 is placed inside the pit 6. Therefore, for example, if many wires 7 are placed in a dense state and the wires 7 are not arranged in an orderly manner, the worker cannot easily determine whether each wire 7 is straddling another wire 7 inside the pit 6.

Specifically, for example, even if there is a wire 7 that crosses over other wires 7 at its midsection as shown in FIG. 2(A), if the midsection of each wire 7 is placed inside a pit 6 as shown in FIG. 2(B), the worker cannot visually determine whether each wire 7 crosses over other wires 7 inside the pit 6.

Therefore, in this case, it is difficult for the worker to determine whether the wire 7 visible at the entrance side of the pit 6 (the wire 7 on the switchboard 5a side) and the wire 7 visible at the exit side of the pit 6 (the wire 7 on the switchboard 5b side) are the same wire. An example of a method for determining the wire is shown below.

First example: A worker checks the identification information, such as the company name and product number, printed on the outer surface of the wire 7 to determine whether it is the same wire as described above. However, if the same company name or product number is printed on multiple wires, the accuracy of the above determination decreases.

Second example: A worker passes a first ring through one end of the wire (known as ring threading), then passes a second ring through the other end of the wire, and advances the first and second rings toward the center. Then, when the first and second rings approach each other near the center and the worker confirms that the first and second rings are on the same wire, he or she determines that they are the same wire. However, with this method, if there is a pit 6, it is necessary to remove the pit 6, which increases the work time and labor required. Furthermore, it is necessary to pass the ring through the wire and advance it toward the center, which also increases the work time and labor required.

Third example: The worker, for example, refers to a ledger (not shown) managed by the manufacturer of each wire 7 to determine whether the wire 7 visible at the entrance side of the pit 6 and the wire 7 visible at the exit side of the pit 6 are the same wire. This method allows the worker to make this determination even when the middle part of each wire 7 is installed inside the pit 6.

However, the ledger managed by the manufacturer of each wire 7 is information that manages the identification information of each wire 7, for example, determined according to rules established by the manufacturer of each wire 7. Therefore, for example, if the manufacturers of each wire 7 are different, the worker must make this determination by referring to each of the ledgers managed by the different manufacturers, and it is not easy to identify the wire 7 to be worked on.

Therefore, in this embodiment, the worker generates management information 201 in advance, which is information for managing the identification information printed on the outer surface of each wire 7 for each wire 7, and stores it in the storage device 2. Then, the terminal device 3 reads, for example, the identification information (hereinafter also referred to as the first identification information) printed on the wire 7 (hereinafter also referred to as the first wire 7) visible on the switchboard 5a side, and the identification information (hereinafter also referred to as the second identification information) printed on the wire 7 (hereinafter also referred to as the second wire 7) visible on the switchboard 5b side. After that, the information processing device 1 compares the first identification information and the second identification information read by the terminal device 3 with the management information 201 stored in the storage device 2 to determine whether the first wire 7 and the second wire 7 are the same wire 7.

In other words, the information processing device 1 in this embodiment determines whether the first wire 7 and the second wire 7 are the same wire 7 (in other words, whether the first identification information and the second identification information are printed on the same wire 7) based on the first identification information printed on the outer surface of the first wire 7 and the second identification information printed on the outer surface of the second wire 7, and multiple pieces of identification information included in the management information 201 stored in the storage device 2.

As a result, the information processing device 1 in this embodiment can determine whether the first wire 7 and the second wire 7 are the same wire even if a portion of each wire 7 (e.g., the middle portion) cannot be seen from the outside, making it easy to identify the wire 7 to be worked on.

In addition, the information processing device 1 in this embodiment refers to management information 201 that manages the identification information printed on each wire 7 according to the same rules, and thereby, for example, even if the manufacturers of each wire 7 are different, it becomes possible to determine whether the first wire 7 and the second wire 7 are the same wire without referring to a ledger managed by the manufacturer of each wire 7. Therefore, the information processing device 1 can easily associate the first wire 7 with the second wire 7.

[Hardware configuration of the determination device]
Next, a description will be given of the hardware configuration of the information processing device 1. FIG.

As shown in FIG. 3, the information processing device 1 has a processor, a CPU 101, a memory 102, a communication device 103, and a storage medium 104. Each part is connected to each other via a bus 105.

The storage medium 104 has a program storage area (not shown) that stores a program (not shown) for performing a process for identifying the wire 7 to be worked on (hereinafter also referred to as a wire identification process). The storage medium 104 may be, for example, a hard disk drive (HDD) or a solid state drive (SSD).

The CPU 101 performs wire identification processing by executing a program loaded from the storage medium 104 to the memory 102.

The communication device 103, for example, accesses a storage device 2 that stores management information 201. The communication device 103 also accesses a terminal device 3, for example, via a network NW such as the Internet.

[Function of the Determination Device]
Next, a description will be given of the functions of the information processing device 1. FIG.

As shown in FIG. 4, the information processing device 1 realizes various functions including an information receiving unit 111, an information management unit 112, an information determination unit 113, and an information output unit 114 by organically cooperating with hardware such as a CPU 101 and a memory 102 and a program.

The information receiving unit 111 receives the identification information printed on the outer surface of each wire 7 from the printing device 4, which prints the identification information on the outer surface of each wire 7.

In addition, the information receiving unit 111 receives from the terminal device 3 the first identification information and the second identification information that the terminal device 3 reads from the outer surface of each wire 7.

The information management unit 112 generates management information 201 from each piece of identification information received by the information receiving unit 111 from the printing device 4. The information management unit 112 then stores the generated management information 201 in the storage device 2, for example. Specific examples of the management information 201 will be described later.

The information determination unit 113 determines whether or not the first wire 7 on which the first identification information is printed and the second wire 7 on which the second identification information is printed are the same wire 7, based on the first identification information and the second identification information received by the information receiving unit 111 from the terminal device 3 and the multiple pieces of identification information included in the management information 201 stored in the storage device 2. Then, the information determination unit 113 generates, for example, information indicating the determination result of whether or not the first wire 7 and the second wire 7 are the same wire 7 (hereinafter also referred to as result information).

The information output unit 114, for example, transmits the result information generated by the information determination unit 113 to the terminal device 3.

[First embodiment]
Next, a first embodiment will be described. Figures 5 and 11 are flow charts for explaining the wire specification process in the first embodiment. Figures 6 to 10 and 12 are diagrams for explaining the wire specification process in the first embodiment.

[Information generation processing]
First, a process for generating the management information 201 (hereinafter also referred to as information generation process) of the wire identification process in the first embodiment will be described. Fig. 5 is a flow chart for explaining the information generation process in the first embodiment.

As shown in FIG. 5, the information receiving unit 111 of the information processing device 1 waits until it receives the identification information printed on the outer surface of each wire 7 from the printing device 4 that prints the identification information on the outer surface of each wire 7 (NO in S11).

Specifically, the information receiving unit 111 receives the printed identification information from the printing device 4, for example, each time the printing device 4 prints the identification information.

Then, when the identification information printed on the outer surface of each wire 7 is received (YES 9 in S11), the information management unit 112 of the information processing device 1 generates management information 201 that holds, for example, for each predetermined unit of wire 7, the multiple identification information printed on the outer surface of each wire 7 in the same order as they were printed on the outer surface of each wire 7 (S12).

Specifically, the information management unit 112 generates management information 201 corresponding to each wire 7, for example, for each wire 7. Also, the information management unit 112 generates management information 201 corresponding to each wire 7, for example, for each drum 8 on which each wire 7 is wound. Note that hereinafter, multiple wires 7 cut out from the same drum 8 are also referred to as a wire group.

Then, the information management unit 112 stores the management information 201 generated in the process of S12 in the storage device 2 (S13). A specific example of the information generation process will be described below.

[Specific example of information generation process]
6 to 9 are diagrams for explaining a specific example of the information generation process. In the following, the case where each piece of identification information is composed of a two-digit number will be explained, but each piece of identification information may be composed of numbers other than two digits, or may be composed of other characters such as English letters or symbols.

For example, as shown in FIG. 6, when the printing device 4 prints the randomly determined identification information "12" at position P1 of the wire 7 removed from the drum 8, the information processing device 1 stores in the storage device 2 management information 201 indicating that the identification information printed on the outer surface of the wire 7 removed from the drum 8 is "12."

Next, for example, as shown in FIG. 7, when the printer 4 prints the randomly determined identification information "43" at position P2 (adjacent to position P1) of the wire 7 removed from the drum 8, the information processing device 1 stores in the storage device 2 management information 201 indicating that the identification information printed on the outer surface of the wire 7 removed from the drum 8 is "12" and "43".

Furthermore, for example, as shown in FIG. 8, when the printer 4 prints the randomly determined identification information "89" at position P3 (adjacent to position P2) of the wire 7 removed from the drum 8, the information processing device 1 stores in the storage device 2 management information 201 indicating that the identification information printed on the outer surface of the wire 7 removed from the drum 8 is "12," "43," and "89."

This enables the information processing device 1 to manage each piece of identification information printed on the outer surface of each wire 7 in the same order as the printing order on the outer surface of each wire 7.

Then, the worker cuts off the wire 7 removed from the drum 8 as necessary. Specifically, the worker cuts off the wire 7a on which the identification information including "12", "43", and "89" is printed, for example, as shown in FIG. 9.

[Examples of management information]
Next, a specific example of the management information 201 will be described. Fig. 10 is a diagram for explaining a specific example of the management information 201. Specifically, Fig. 10 is a diagram for explaining a specific example of the management information 201 in which each piece of identification information is managed for each drum 8 on which each wire 7 is wound.

The management information 201 shown in FIG. 10 has the following items: "Drum ID," in which identification information for each drum 8 is set, and "Identification Information," in which identification information for each wire 7 cut out from each drum 8 is set. The management information 201 shown in FIG. 10 also has the following items: "Manufacturer," in which the manufacturer of the wire 7 for each drum 8 is set, and "Manufacturing Date," in which the manufacturing date of the wire 7 for each drum 8 is set.

Specifically, in the management information 201 shown in FIG. 10, the information in the first line has "D01" set as the "drum ID," "55, 23, 16, 81, 41, 99, 21, 59, 04, ..., 29, 73" set as the "identification information," "Company A" set as the "manufacturer," and "2018/04/01" set as the "manufacturing date."

In the management information 201 shown in FIG. 10, the second line of information has "D02" set as the "drum ID", "12, 43, 89, 74, 55, 67, 31, 62, 07, ..., 71, 38" set as the "identification information", "Company B" set as the "manufacturer", and "2015/08/01" set as the "manufacturing date". The drum with "Drum ID" "D02" corresponds to the drum 8 described in FIG. 6 to FIG. 9. The description of other information included in FIG. 10 is omitted. It is sufficient that the order of the identification numbers stored in the management information 201 and the order of the identification numbers printed on the outer surface of the wire 7 by the printing device 4 are the same, and may be, for example, "38, 71, ..., 07, 62, 31, 67, 55, 74, 89, 43, 12".

[Main process of wire identification process (1)]
Next, a description will be given of the main processing of the wire specification processing in the first embodiment. Fig. 11 is a flow chart for explaining the main processing of the wire specification processing in the first embodiment.

11, the information receiving unit 111 of the information processing device 1 waits, for example, until it receives the first identification information and the second identification information printed on the outer surfaces of the first wire 7 and the second wire 7 from the terminal device 3 (NO in S21, NO in S22). That is, the information receiving unit 111 waits, for example, until the terminal device 3 reads the first identification information and the second identification information.

Then, when the first identification information and the second identification information are received from the terminal device 3 (YES in S21, YES in S22), the information determination unit 113 of the information processing device 1 refers to the management information 201 stored in the storage device 2 and determines whether or not management information 201 exists that includes the first identification information received in the processing of S21 and the second identification information received in the processing of S22 (S23).

As a result, when it is determined that management information 201 including the first identification information and the second identification information exists (YES in S24), the information output unit 114 of the information processing device 1 outputs result information indicating that the first wire 7 having the first identification information printed on its outer surface and the second wire 7 having the second identification information printed on its outer surface are the same wire 7 (S25). Specifically, in this case, the information output unit 114 transmits, for example, result information indicating that the first wire 7 and the second wire 7 are the same wire 7 to the terminal device 3.

On the other hand, if it is determined that management information 201 including the first identification information and the second identification information does not exist (NO in S24), the information output unit 114 does not perform the process of S25. In this case, the information output unit 114 may transmit, for example, result information indicating that the first wire 7 and the second wire 7 are not the same wire 7 to the terminal device 3.

As a result, the worker can obtain information as to whether the first wire 7 and the second wire 7 whose identification information has been read are the same wire 7, for example, by viewing the terminal device 3 on which the result information is displayed. Therefore, the worker can use the information obtained from the terminal device 3 to perform work such as removing each wire 7. Below, a specific example of the main process of the wire identification process will be described.

[Specific example (1) of main process of wire identification process]
FIG. 12 is a diagram illustrating a specific example of the main process of the wire identification process in the first embodiment.

For example, in the information in the second row of the management information 201 described in FIG. 10 (information in which the "drum ID" is "D02"), "89" and "07" are set as the "identification information". Therefore, for example, as shown in FIG. 12, if the first identification information printed on the outer surface of the first wire 7 (one of the multiple wires 7 connected to the switchboard 5a) is "89" and the second identification information printed on the outer surface of the second wire 7 (one of the multiple wires 7 connected to the switchboard 5b) is "07", the information processing device 1 determines that the first wire 7 and the second wire 7 are the same wire 7 (wire 7a described in FIG. 9).

In this way, the information processing device 1 in the first embodiment determines that the first wire 7 and the second wire 7 are the same wire 7 when the first identification information printed on the outer surface of the first wire 7 and the second identification information printed on the outer surface of the second wire 7 are stored in the storage device 2 corresponding to one wire (for example, one wire with a "drum ID" of "D02").

This allows the information processing device 1 to determine whether the first wire 7 and the second wire 7 are the same wire even when the middle portion of each wire 7 cannot be seen from the outside. Therefore, the information processing device 1 can easily identify the wire 7 to be worked on (identify the overall image of the wire 7 to be worked on).

In particular, in recent years, there has been an increase in cases where installed wires 7 are removed due to deterioration of electrical equipment, and further, there are cases where the wires 7 to be removed need to be cut when removing the installed wires 7. Therefore, the information processing device 1 makes it possible to easily identify the overall image of the wires 7 to be removed even when the middle portions of each wire 7 cannot be seen from the outside, thereby making it possible to greatly contribute to preventing accidents such as the erroneous cutting of wires 7 other than the wires 7 to be removed.

In FIG. 12, one terminal device 3 reads two pieces of identification information and transmits them to the information processing device 1, but two terminal devices may each read one piece of identification information and transmit it to the information processing device 1. For example, a first terminal device may read "89" as the identification information and transmit it to the information processing device 1, and a second terminal device may read "07" as the identification information and transmit it to the information processing device 1.

[Second embodiment]
Next, a second embodiment will be described. Fig. 13 is a diagram for explaining a schematic configuration diagram of an information processing system 10 in the second embodiment. Fig. 14 is a flow chart for explaining a wire identification process in the second embodiment. Fig. 15 is a diagram for explaining the wire identification process in the second embodiment.

In the wire identification process in the second embodiment, for example, the first identification information printed on the outer surface of the first wire 7, the second identification information printed on the outer surface of the second wire 7, and the identification information (hereinafter also referred to as intermediate identification information or third identification information) printed on the outer surface of another wire 7 (hereinafter also referred to as intermediate wire 7 or third wire 7) visible in the region between the first wire 7 and the second wire 7 are used to determine whether the first wire 7, the intermediate wire 7, and the second wire 7 are the same wire 7 (in other words, whether the first identification information, intermediate identification information, and second identification information are printed on the same wire 7).

Specifically, the information processing device 1 in the second embodiment identifies the wire 7 to be worked on from among multiple wires 7 whose middle portions are installed in two pits 6 (pits 6a and 6b), as shown in FIG. 13. Note that, as in the first embodiment, the following description will be given assuming that the wire 7 whose end is visible on the switchboard 5a side is the first wire 7, and the wire 7 whose end is visible on the switchboard 5b side is the second wire 7. Also, the following description will be given assuming that the wire 7 visible between pits 6a and 6b is the intermediate wire 7.

[Main process of wire identification process (2)]
Next, the main process of the wire identification process in the second embodiment will be described. Fig. 14 is a flow chart for explaining the main process of the wire identification process in the second embodiment. Note that the information generation process in the second embodiment is the same as that in the first embodiment, and therefore the description thereof will be omitted.

As shown in FIG. 14, the information receiving unit 111 waits until it receives from the terminal device 3 the first identification information, intermediate identification information, and second identification information printed on the outer surfaces of the first wire 7, the intermediate wire 7, and the second wire 7, respectively (NO in S31, NO in S32, NO in S33). Note that hereinafter, it is assumed that the first identification information, intermediate identification information, and second identification information are printed in this order. The terminal device 3 may also transmit information indicating the printing order of the first identification information, intermediate identification information, and second identification information together with the identification information.

When the first identification information, intermediate identification information, and second identification information are received from the terminal device 3 (YES in S31, YES in S32, YES in S33), the information determination unit 113 refers to the management information 201 stored in the storage device 2 and determines whether or not management information 201 exists that includes the first identification information received in the process of S31, the intermediate identification information received in the process of S32, and the second identification information received in the process of S33, in that order (S34). When the information indicating the printing order is received, the information determination unit 113 identifies the printing order of the first identification information, intermediate identification information, and second identification information based on the information indicating the printing order, and executes the determination process of S34.

As a result, when it is determined that management information 201 exists that includes the first identification information, intermediate identification information, and second identification information in this order (YES in S35), the information output unit 114 outputs result information indicating that the first wire 7 having the first identification information printed on its outer surface, the intermediate wire 7 having the intermediate identification information printed on its outer surface, and the second wire 7 having the second identification information printed on its outer surface are the same wire 7 (S36). Specifically, in this case, the information output unit 114 transmits result information indicating that the first wire 7, the intermediate wire 7, and the second wire 7 are the same wire 7 to the terminal device 3, for example.

On the other hand, if it is determined that there is no management information 201 that includes the first identification information, the intermediate identification information, and the second identification information in this order (NO in S35), the information output unit 114 does not perform the process of S36. In this case, the information output unit 114 may transmit, for example, result information indicating that at least two of the first wire 7, the intermediate wire 7, and the second wire 7 are not the same wire 7 to the terminal device 3.

In other words, when three pieces of identification information (first identification information, intermediate identification information, and second identification information) that may be identification information printed on the outer surface of the same wire 7 are read, the information processing device 1 uses the three pieces of identification information that have been read to determine whether the wire 7 to which each piece of identification information is attached is the same wire 7.

Here, the management information 201 is information that manages the identification information printed on the outer surface of each wire 7 in the same order as the printing order on the outer surface of each wire 7. Therefore, if the first wire 7, the intermediate wire 7, and the second wire 7 are the same wire 7, it can be determined that the management information 201 holds the first identification information, intermediate identification information, and second identification information in this order.

Therefore, in the process of S34, the information processing device 1 in the second embodiment determines whether or not management information 201 exists that does not simply include the first identification information, intermediate identification information, and second identification information, but includes the first identification information, intermediate identification information, and second identification information in this order. Then, when the information processing device 1 determines that management information 201 exists that includes the first identification information, intermediate identification information, and second identification information in this order, it determines that the first wire 7 with the first identification information printed on its outer surface, the intermediate wire 7 with the intermediate identification information printed on its outer surface, and the second wire 7 with the second identification information printed on its outer surface are the same wire 7.

This allows the information processing device 1 to easily determine whether the first wire 7, the intermediate wire 7, and the second wire 7 are the same wire 7. Below, a specific example of the main process of the wire identification process is described.

[Specific example (2) of main process of wire identification process]
FIG. 15 is a diagram illustrating a specific example of the main process of the wire identification process in the second embodiment.

For example, in the information in the second row of the management information 201 described in FIG. 10 (information in which the "drum ID" is "D02"), "89", "67" and "07" are set as the "identification information" in this order. Therefore, for example, as shown in FIG. 15, if the first identification information printed on the outer surface of the first wire 7 visible on the switchboard 5a side is "89", the intermediate identification information printed on the outer surface of the intermediate wire 7 visible between the pits 6a and 6b is "67", and the second identification information printed on the outer surface of the second wire 7 visible on the switchboard 5b side is "07", the information processing device 1 determines that the first wire 7, the intermediate wire 7 and the second wire 7 are the same wire 7 (wire 7a described in FIG. 9).

In this way, the information processing device 1 in the second embodiment determines whether the first wire 7, the intermediate wire 7, and the second wire 7 are the same wire 7 based on the first identification information printed on the outer surface of the first wire 7, the second identification information printed on the outer surface of the second wire 7, the intermediate identification information printed on the outer surface of the intermediate wire 7, and multiple pieces of identification information included in the management information 201 stored in the storage device 2.

This enables the information processing device 1 to determine whether the first wire 7, the intermediate wire 7, and the second wire 7 are the same wire even when the middle portion of each wire 7 cannot be seen from the outside, making it easy to identify the wire 7 to be worked on.

In FIG. 15, one terminal device 3 reads three pieces of identification information and transmits them to the information processing device 1, but three terminal devices may each read one piece of identification information and transmit it to the information processing device 1. For example, the first terminal device may read "89" as the identification information and transmit it to the information processing device 1, the second terminal device may read "67" as the identification information and transmit it to the information processing device 1, and the third terminal device may read "07" as the identification information and transmit it to the information processing device 1. In this case, as described above, the first to third terminal devices transmit to the information processing device 1 sequence information indicating the printing sequence of the identification information they have read. For example, the first terminal device transmits sequence information indicating that the printing sequence is first along with the identification information "89". The second terminal device transmits sequence information indicating that the printing sequence is second along with the identification information "67". The third terminal device transmits sequence information indicating that the printing sequence is third along with the identification information "07".

[Third embodiment]
Next, a third embodiment will be described. Fig. 16 is a flow chart for explaining the wire specification process in the third embodiment. Fig. 17 is a diagram for explaining the wire specification process in the third embodiment.

In the wire identification process in the third embodiment, a plurality of first identification information (a plurality of first identification information printed consecutively) is read from the first wire 7, and a plurality of second identification information (a plurality of second identification information printed consecutively) is read from the second wire 7. In the wire identification process in the third embodiment, the plurality of first identification information and the plurality of second identification information are used to determine whether the first wire 7 and the second wire 7 are the same wire 7.

[Main process of wire identification process (3)]
Next, the main process of the wire identification process in the third embodiment will be described. Fig. 16 is a flow chart for explaining the main process of the wire identification process in the third embodiment. Note that the information generation process in the third embodiment is the same as that in the first embodiment, and therefore the description thereof will be omitted.

As shown in FIG. 16, the information receiving unit 111 waits until it receives, from the terminal device 3, a plurality of first identification information printed on the outer surface of the first wire 7 and a plurality of second identification information printed on the outer surface of the second wire 7 (NO in S41, NO in S42).

Then, when a plurality of first identification information and a plurality of second identification information are received from the terminal device 3 (YES in S41, YES in S42), the information determination unit 113 refers to the management information 201 stored in the storage device 2 and determines whether or not management information 201 exists that includes the plurality of first identification information received in the process of S41 in the same order as the printing order on the first wire 7, and that includes the plurality of second identification information received in the process of S42 in the same order as the printing order on the second wire 7 (S43).

As a result, when it is determined that management information 201 exists that includes multiple first identification information in the same order as the printing order on the first wire 7 and multiple second identification information in the same order as the printing order on the second wire 7 (YES in S44), the information output unit 114 outputs result information indicating that the first wire 7 with multiple first identification information printed on its outer surface and the second wire 7 with multiple second identification information printed on its outer surface are the same wire 7 (S45). Specifically, in this case, the information output unit 114 transmits result information indicating that the first wire 7 and the second wire 7 are the same wire 7 to the terminal device 3, for example.

On the other hand, if it is determined that there is no management information 201 that contains multiple first identification information in the same order as the printing order on the first wire 7 and multiple second identification information in the same order as the printing order on the second wire 7 (NO in S44), the information output unit 114 does not perform the process of S45. In this case, the information output unit 114 may transmit, for example, result information indicating that the first wire 7 and the second wire 7 are not the same wire 7 to the terminal device 3.

As described above, the reason for referencing multiple pieces of first identification information and multiple pieces of second identification information will be described. For example, assume that there are a large number of wires 7 connecting the switchboard 5a and the switchboard 5b, and that one wire has the identification information "89" and the identification information "62" printed thereon, and the other wires also have the same identification information "89" and the identification information "62" printed thereon. In this assumption, when the information processing device 1 receives the identification information "89" of one wire and the identification information "62" of the other wire from the terminal device 3 and performs a determination process, it is determined that the one wire and the other wire are the same wire because the identification information "89" and the identification information "62" are printed on both wires. In this case, the information processing device 1 cannot accurately identify the wire 7 to be worked on.

Therefore, in the third embodiment, the uniqueness of the identification information is increased by increasing the amount of identification information that serves as the basis for judgment, in other words, the amount of information in the identification information to be read, specifically by using a number with more than two digits as the identification information. The greater the amount of information in the identification information (for example, the greater the number of digits), the lower the probability that the same identification information will be printed in the same order on different wires and stored as management information. In other words, the greater the amount of information in the identification information that serves as the basis for judgment, the higher the accuracy of the judgment.

In this way, the information processing device 1 can accurately determine whether the first wire 7 and the second wire 7 are the same wire 7, even when there is a large number of wires 7 connecting the switchboard 5a and the switchboard 5b. Below, a specific example of the main process of the wire identification process is described.

[Specific example (3) of main process of wire identification process]
FIG. 17 is a diagram illustrating a specific example of the main process of the wire identification process in the third embodiment.

For example, in the information on the second line of the management information 201 described in FIG. 10 (information in which the "drum ID" is "D02"), "89" and "74" are consecutively set as "identification information". In addition, in the information on the second line of the management information 201 described in FIG. 10, "62" and "07" are consecutively set as "identification information". Therefore, for example, as shown in FIG. 17, if the first identification information printed consecutively on the outer surface of the first wire 7 visible on the switchboard 5a side is "89" and "74", and the second identification information printed consecutively on the outer surface of the second wire 7 visible on the switchboard 5b side is "62" and "07", the information processing device 1 determines that the first wire 7 and the second wire 7 are the same wire 7 (wire 7a described in FIG. 9).

In this way, the information processing device 1 in this embodiment determines whether the first wire 7 and the second wire 7 are the same wire 7 based on the multiple first identification information printed consecutively on the outer surface of the first wire 7 and the multiple second identification information printed consecutively on the outer surface of the second wire 7, and the multiple identification information included in the management information 201 stored in the storage device 2.

This enables the information processing device 1 to accurately determine whether the first wire 7 and the second wire 7 are the same wire 7, even when, for example, there is a large number of wires 7 connecting the switchboard 5a and the switchboard 5b.

[Modification (1) of the third embodiment]
Next, a first modified example of the third embodiment will be described with reference to Fig. 18. The first modified example of the third embodiment will be described with reference to Fig. 18.

For example, when printing identification information at each position on the wire 7 removed from the drum 8, the printing device 4 may print identification information corresponding to each position as well as identification information corresponding to positions adjacent to each position.

Specifically, as shown in FIG. 18, for example, at position P1 of the wire 7 removed from the drum 8, the printing device 4 prints "12", which is the identification information corresponding to position P1, as well as "43", which is the identification information corresponding to position P2 adjacent to position P1.

As shown in FIG. 18, for example, at position P2 of the wire 7 removed from the drum 8, the printing device 4 prints "43", which is the identification information corresponding to position P2, as well as "12" and "89", which are the identification information corresponding to positions P1 and P3 adjacent to position P2, respectively.

This allows the terminal device 3 to read, for example, the identification information printed in one location on the outer surface of the first wire 7, thereby reading multiple first identification information printed consecutively on the outer surface of the first wire 7. Similarly, the terminal device 3 can read, for example, the identification information printed in one location on the outer surface of the second wire 7, thereby reading multiple second identification information printed consecutively on the outer surface of the second wire 7. This allows the worker to reduce the workload required to read the identification information printed on the outer surfaces of the first wire 7 and the second wire 7.

[Modification (2) of the third embodiment]
Next, a second modification of the third embodiment will be described with reference to Fig. 19. The second modification of the third embodiment will be described with reference to Fig. 19.

For example, when printing identification information at each position on the wire 7 removed from the drum 8, the printing device 4 may print additional information (e.g., a serial number indicating the printing order of the identification information) that has a predetermined relationship with the identification information corresponding to each position and the identification information corresponding to the adjacent positions, in addition to the identification information corresponding to each position.

Specifically, as shown in FIG. 19, for example, at position P1 of the wire 7 removed from the drum 8, the printing device 4 prints "12", which is the identification information corresponding to position P1, as well as "01", which indicates that the "12" is the first to be printed on the wire 7.

As shown in FIG. 19, for example, at position P2 of the wire 7 removed from the drum 8, the printing device 4 prints "43", which is the identification information corresponding to position P2, as well as "02", which indicates that "43" is the second to be printed on the wire 7.

This allows the worker to, for example, identify the length of each wire 7 by referring to the additional information printed on each wire 7.

Specifically, for example, when the printer 4 prints identification information every 1 (m) on the outer surface of the wire 7 removed from the drum 8, if there is a wire 7 with the additional information "35" and "50" printed on both ends, the worker can determine that the length of that wire 7 is 15 (m), calculated by subtracting 35 (m) from 50 (m).
