[Brief description of the drawings]

[0009] [Figure 1] FIG. 1 is a configuration diagram showing a configuration of a wiring checking system according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a diagram showing the configuration of the long cable 150. As shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] A wiring checking system according to an embodiment of the present invention will be described below with reference to Fig. 1. This distribution system includes a code reader 101, a storage device 102, and a display device 103.

[0011] The code reader 101 reads codes provided at the terminals of the first device 104 and the second device 105. The first device 104 has, for example, a first terminal 106 and a third terminal 108. The second device 105 has, for example, a second terminal 107 and a fourth terminal 109. The code reader 101 also reads codes provided on the first distribution cable 111 and the second distribution cable 112.

[0012] Each of the first distribution cable 111 and the second distribution cable 112 is produced by cutting a long cable 150 shown in Fig. 2. The long cable 150 is provided with a plurality of first cable cords 131a, 132a, 133a, and 134a at a plurality of identification points provided at regular intervals from a first end 151.

[0013] Each of the plurality of first cable cords 131a, 132a, 133a, and 134a is provided with cable identification information for identifying the long cable 150, distance information from a first end 151 of the long cable 150, and first direction information indicating the direction of the first end 151. In addition, a plurality of second cable cords 131b, 132b, 133b, and 134b are provided at locations adjacent to each of the first cable cords 131a, 132a, 133a, and 134a. Each of the plurality of second cable cords 131b, 132b, 133b, and 134b is provided with cable identification information, distance information, and second direction information indicating the direction of a second end 152 of the long cable 150 different from the first end 151.

[0014] A first code 121 is provided at the location of the first terminal 106 connected to the first connection end 111a of the first distribution cable 111. The first code 121 includes first device identification information for identifying the first device 104 and first terminal identification information for identifying the first terminal 106.

[0015] A second code 122 is provided at the location of the second terminal 107 connected to a second connection end 111b different from the first connection end 111a of the first distribution cable 111. Second device identification information for identifying the second device 105 and second terminal identification information for identifying the second terminal 107 are written on the second code 122.

[0016] Further, a third code 123 is provided at the location of the third terminal 108 connected to the third connection end 112a of the second distribution cable 112. The third code 123 has the first device identification information and the third terminal identification information for identifying the third terminal 108 written thereon.

[0017] Further, a fourth code 124 is provided at a location of the fourth terminal 109 connected to a fourth connection end 112b different from the third connection end 112a of the second distribution cable 112. The fourth code 124 has second device identification information and fourth terminal identification information for identifying the fourth terminal 109 written thereon.

[0018] The above-mentioned code may be, for example, a well-known barcode or a two-dimensional barcode.

[0019] The storage device 102 stores information on the code read by the code reader 101. First, the storage device 102 stores first connection information including first device identification information and first terminal identification information of the first code 121 read by the code reader 101, and cable identification information, distance information, and directional information (first directional information or second directional information) of the cable code read by the code reader 101 in combination with the first code 121.

[0020] Next, second connection information consisting of the second device identification information and second terminal identification information of the second code 122 read by the code reader 101, and the cable identification information, distance information, and directional information (first directional information or second directional information) of the cable code read by the code reader 101 in combination with the second code 122 is stored in the memory unit 102.

[0021] Next, third connection information consisting of the first device identification information and third terminal identification information of the third code 123 read by the code reader 101, and the cable identification information, distance information, and directional information (first directional information or second directional information) of the cable code read by the code reader 101 in combination with the third code 123 is stored in the memory unit 102.

[0022] Next, fourth connection information consisting of the second device identification information and fourth terminal identification information of the fourth code 124 read by the code reader 101, and the cable identification information, distance information, and directional information (first directional information or second directional information) of the cable code 134b read by the code reader 101 in combination with the fourth code 124 is stored in the memory unit 102.

[0023] The display device 103 displays the first connection information, the second connection information, the third connection information, and the fourth connection information stored in the storage device 102. The storage device 102 may be a computer device such as a server. The storage device 102 may be connected to the code reader 101 and the display device 103 via a network. The code reader 101 and the display device 103 may be mobile terminal devices.

[0024] For example, when connecting a wiring cable between first terminal 106 of first device 104 and second terminal 107 of second device 105, a person performing wiring work uses code reader 101 to read first cord 121 and a first cable cord that is closest to first cord 121 of the wiring cable connected to first terminal 106. Furthermore, the person uses code reader 101 to read second cord 122 and a second cable cord that is closest to second cord 122 of the wiring cable connected to second terminal 107.

[0025] Similarly, when connecting the third terminal 108 of the first device 104 and the fourth terminal 109 of the second device 105 with a distribution cable, the person in charge uses the code reader 101 to read the third cord 123 and the first cable cord that is closest to the third cord 123 of the distribution cable connected to the third terminal 108. Furthermore, the person in charge uses the code reader 101 to read the fourth cord 124 and the second cable cord that is closest to the fourth cord 124 of the distribution cable connected to the fourth terminal 109.

[0026] The information of the codes read as described above (first connection information, second connection information, third connection information, fourth connection information) is stored in storage device 102. For example, the connection information shown in Table 1 below is stored in storage device 102. The connection information in Table 1 stored in storage device 102 is displayed on display device 103 and can be visually confirmed by the person in charge. Here, the display information shown in Table 1 indicates a correctly wired state.

[0027] On the other hand, if the wiring is incorrect, the connection information shown in the following Table 2 is stored in the storage device 102 and displayed on the display device 103.

[0028] [Table 1]

[0029] [Table 2]

[0030] In the first connection information shown in Table 1, the first terminal 106 having the identification information "port1" is combined with the distance information "10" and the direction information "left". In addition, in the second connection information, the second terminal 107 having the identification information "port2" connected to the first terminal 106 is combined with the distance information "30" and the direction information "right". In addition, in the third connection information, the third terminal 108 having the identification information "port3" is combined with the distance information "40" and the direction information "left". In addition, in the fourth connection information, the fourth terminal 109 having the identification information "port4" connected to the third terminal 108 is combined with the distance information "80" and the direction information "left". In addition, all of them have the same cable identification.

[0031] In this case, it can be determined from the first connection information and the second connection information that the first terminal 106 and the second terminal 107 are connected by a distribution cable (first distribution cable 111) cut at a distance of 10 m and a distance of 30 from the first end 151 of the long cable 150. Also, it can be determined from the third connection information and the fourth connection information that the third terminal 108 and the fourth terminal 109 are connected by a distribution cable (second distribution cable 112) cut at a distance of 40 m and a distance of 80 from the first end 151 of the long cable 150. There is no contradiction in the existence of a distribution cable cut at a distance of 10 m and a distance of 30 and a distribution cable cut at a distance of 40 m and a distance of 80.

[0032] Meanwhile, in the first connection information shown in Table 2, the first terminal 106 having the identification information "port1" is combined with the distance information "10" and the direction information "left". In addition, in the second connection information, the second terminal 107 having the identification information "port2" connected to the first terminal 106 is combined with the distance information "80" and the direction information "right". In addition, in the third connection information, the third terminal 108 having the identification information "port3" is combined with the distance information "40" and the direction information "left". In addition, in the fourth connection information, the fourth terminal 109 having the identification information "port4" connected to the third terminal 108 is combined with the distance information "30" and the direction information "left". In addition, all of them have the same cable identification.

[0033] In this case, it can be determined from the first connection information and the second connection information that the first terminal 106 and the second terminal 107 are connected by a distribution cable cut at a distance of 10 m and a distance of 80 from the first end 151 of the long cable 150. Also, it can be determined from the third connection information and the fourth connection information that the third terminal 108 and the fourth terminal 109 are connected by a distribution cable cut at a distance of 40 m and a distance of 30 from the first end 151 of the long cable 150. The existence of a distribution cable cut at a distance of 10 m and a distance of 80 and a distribution cable cut at a distance of 40 m and a distance of 30 is inconsistent, and it can be determined that a wiring error has occurred.

[0034] Also, factors to be considered in the determination include whether or not the two terminals to be connected are connected by a distribution cable with the same cable identification, and whether or not the direction information is reversed.

[0035] As described above, according to the present invention, the terminals of each device and the connection ends of the distribution cables are provided with codes bearing identification information for identifying each device, so that wiring checks can be carried out more quickly. According to the present invention, since wiring errors can be detected in the state in which the wiring is performed, wiring errors can be detected before the power is turned on to the devices.

[0036] It should be noted that the present invention is not limited to the above-described embodiments, and it is apparent that many modifications and combinations can be made by a person having ordinary knowledge in the art within the technical concept of the present invention.
