[0023] The following is a detailed description with reference to the accompanying drawings. Repeated descriptions are appropriately simplified or omitted. In each figure, the same reference numerals represent the same parts or corresponding parts.

[0024] Implementation Method 1

[0025] Figure 1 1 is a diagram showing an example of a security system 1. First, referring to Figure 1 The security system 1 will be described. The security system 1 includes a door 2 , an electronic lock 3 , a control device 4 , and a reader 5 .

[0026] The door 2 is provided at a place where passage management is required. The electronic lock 3 is provided inside the door 2. An internal connector 7 is provided on the internal wiring 6 extending from the electronic lock 3. An internal connector 8 is connected to the internal connector 7. The internal connector 8 is provided at one end of the internal wiring 9. The internal wiring 9 is configured to extend from the inside of the door 2 to the inside of the wall adjacent to the door 2. The internal wiring 6, the internal connector 7, the internal connector 8, and one end side of the internal wiring 9 are configured inside the door 2.

[0027] An internal connector 10 is provided at the other end of the internal wiring 9. That is, the internal wiring 9 connects the internal connector 8 and the internal connector 10. The internal connector 11 is connected to the internal connector 10. The internal connector 11 is provided at one end of the internal wiring 12. The internal wiring 12 is connected to the control device 4.

[0028] The reading device 5 reads the identification information from the storage medium. As an example, the reading device 5 is a card reader. In this case, the storage medium is a tag built into a card such as an employee ID card. For example, a user of the system places his or her employee ID card on the card reader. As a result, the card reader reads the identification information from the tag built into the employee ID card. The identification information read by the card reader is sent to the control device 4.

[0029] The control device 4 controls the electronic lock 3 and the reader 5. The control device 4 is connected to the electronic lock 3 via at least the internal wiring 6 and the internal wiring 9. Other internal connectors and other internal wirings may also exist between the electronic lock 3 and the control device 4. As an example, if the reader 5 does not read the identification information, the control device 4 locks the door 2 through the electronic lock 3. When the identification information read by the reader 5 is consistent with the registered identification information, the control device 4 controls the electronic lock 3 and unlocks the door 2.

[0030] In the security system 1, each time the door 2 is opened or closed, the internal wiring 9 is bent. Therefore, the internal wiring 9 is easily disconnected. When the internal wiring 9 is disconnected, the electronic lock 3 cannot operate normally. When such an unfavorable situation occurs, the maintenance personnel go to the site to perform operations for eliminating the unfavorable situation. In this operation, the disconnection check is first performed. Next, the disconnection check device 20 used by the maintenance personnel when performing the disconnection check is described.

[0031] Figure 2 and Figure 3 1 is a diagram showing an example of a disconnection inspection device 20 in Embodiment 1. The disconnection inspection device 20 includes a connector 21 , a terminal for inspection 22 , and wiring 23 .

[0032] The connector 21 can be attached to and detached from the internal connector 8. As an example, the connector 21 is a connector of the same type as the internal connector 7. That is, the connector 21 has the same shape as the internal connector 7. Figure 2 and Figure 3 In the example shown, the connector 21 includes a main body 24 and nine pins 25. The pins 25 are arranged inside the main body 24. When the connector 21 includes the pins 25, nine holes into which the pins 25 are inserted are formed in the internal connector 8 connected to the connector 21.

[0033] The inspection terminal 22 is a terminal connected to the inspection terminal 14 of the circuit meter 13 during the disconnection inspection. As an example, the inspection terminal 22 is a connector of the same type as the internal connector 8. That is, the inspection terminal 22 has the same shape as the internal connector 8. Figure 2 and Figure 3 In the example shown, the inspection terminal 22 has a main body 26 formed with nine holes 26a. The inspection terminal 14 of the circuit meter 13 is a probe. When performing a disconnection inspection, the inspection terminal 14 is inserted into the hole 26a.

[0034] The wiring 23 connects the connector 21 and the inspection terminal 22 . Figure 2 and Figure 3 The example shown is that the wiring 23 includes a line extending from the connector 21 and a line extending from the inspection terminal 22 , and these lines are connected by crimping.

[0035] Next, refer to Figure 4 to Figure 7 Description Figure 1 In the safety system 1 shown, a method in which a maintenance worker performs a wire breakage inspection using the wire breakage inspection device 20 . Figure 4 This is a flowchart showing the disconnection inspection method in the first embodiment. Figure 5 to Figure 7 This is a diagram for explaining the method of checking for wire breakage.

[0036] The maintenance worker removes the electronic lock 3 disposed inside the door 2 from the door 2 (S101). Figure 5 As shown, a cover 15 is provided on the end surface 2a of the door 2. The maintenance worker removes the cover 15 from the main body of the door 2. As a result, an opening 2b communicating with the space where the electronic lock 3 is arranged appears on the end surface 2a of the door 2. When the maintenance worker operates from the opening 2b to remove the electronic lock 3, the removed electronic lock 3 is pulled out of the door 2 from the opening 2b. Figure 6 The electronic lock 3 is shown in a state where it is pulled out to the outside of the door 2 .

[0037] As described above, the internal wiring 6 extends from the electronic lock 3. In addition, the internal connector 7 provided on the internal wiring 6 is connected to the internal connector 8. Therefore, by pulling the electronic lock 3 out of the opening 2b to the outside of the door 2, as shown in FIG. Figure 6 As shown, the internal connector 7 and the internal connector 8 are also pulled out from the opening 2b to the outside of the door 2 (S102). Figure 6 In FIG. 1 , a state where the inner connector 7 and the inner connector 8 are pulled out to the outside of the door 2 is shown by a solid line, and a state before being pulled out is shown by a dotted line.

[0038] When the maintenance worker pulls the inner connector 7 and the inner connector 8 out of the door 2 , the inner connector 7 is removed from the inner connector 8 ( S103 ).

[0039] Next, the maintenance worker installs the disconnection inspection device 20 on the internal connector 8 from which the internal connector 7 has been removed. Specifically, the maintenance worker connects the connector 21 of the disconnection inspection device 20 to the internal connector 8 (S104). Next, the maintenance worker connects the inspection terminal 14 of the circuit meter 13 to the inspection terminal 22 (S105). If the inspection terminal 14 is a probe, the maintenance worker connects the inspection terminal 14 to the inspection terminal 22 by inserting the inspection terminal 14 into the hole 26a.

[0040] By connecting the connector 21 to the internal connector 8 and connecting the inspection terminal 14 to the inspection terminal 22 , the inspection terminal 14 is electrically connected to the internal wiring 9 . Figure 7 The state of electrical connection between the inspection terminal 14 and the internal wiring 9 is shown. Figure 7 In the state shown, the door 2 is opened and closed to perform a wire breakage check (S106).

[0041] Sometimes, a disconnection occurs only when the door 2 is moved in a specific manner or when the door 2 is placed in a specific position. Therefore, in S106, the maintenance worker determines whether the disconnection exists while moving the door 2. For example, the maintenance worker moves the door 2 while observing the resistance value displayed in the circuit meter 13, thereby confirming the conduction between the inspection terminal 22 and the control device 4. During the period of detecting the conduction by the circuit meter 13, a buzzer may be emitted from the circuit meter 13.

[0042] In the example shown in the present embodiment, when the disconnection check is performed, the connector 21 is connected to the internal connector 8, and the inspection terminal 14 is connected to the inspection terminal 22. When the disconnection check is performed, the inspection terminal 14 is not directly connected to the internal connector 8. Therefore, during the inspection, there is no accident that the hole formed in the internal connector 8 is enlarged by the inspection terminal 14. According to the example shown in the present embodiment, when the disconnection check is performed in the security system 1 having the electronic lock 3, it is possible to prevent the connector of the system 1 from being damaged.

[0043] Next, other functions that can be adopted by the present wire breakage inspection device 20 and other steps that can be adopted by the present wire breakage inspection method will be described.

[0044] As described above, the maintenance worker performs the disconnection check while moving the door 2. Therefore, when performing the disconnection check, it is preferred that the maintenance worker's hands are free. For such reasons, the circuit meter 13 may also have a first fixing component for fixing the main body part to the door 2 in a detachable manner. The first fixing component is, for example, a magnet. As another example, the inspection terminal 22 of the disconnection inspection device 20 may also have a second fixing component for fixing the main body 26 to the door 2 in a detachable manner. The second fixing component is, for example, a magnet.

[0045] When the circuit meter 13 has a first fixing member, the maintenance worker fixes the circuit meter 13 to the door 2 before performing the disconnection check in S106. Then, the door 2 is moved while the circuit meter 13 is fixed to the door 2 to check whether there is a disconnection. The step of fixing the circuit meter 13 to the door 2 may also be performed before S103. In addition, when the inspection terminal 22 has a second fixing member, the maintenance worker may also fix the inspection terminal 22 to the door 2 when fixing the circuit meter 13 to the door 2.

[0046] In the case where a commercially available circuit meter without the first fixing member is used as the circuit meter 13, the inspection terminal 22 may further include a holding member for holding the circuit meter 13. The holding member is a member for holding the circuit meter 13 by the main body 26 fixed to the door 2 by the second fixing member. If the inspection terminal 22 includes the second fixing member and the holding member, even if the circuit meter 13 cannot be directly fixed to the door 2, the maintenance worker can also hold the circuit meter 13 by the holding member after fixing the inspection terminal 22 to the door 2.

[0047] In order to prevent the inspection terminal 14 from falling off from the inspection terminal 22 when the door 2 is opened or closed, the inspection terminal 22 may further include a holding mechanism for holding the inspection terminal 14 connected.

[0048] Figure 82 is a diagram showing another example of the disconnection inspection device 20. The shape of the internal connector 8 included in the safety system 1 varies depending on the manufacturer. Figure 2 The wire breakage inspection device 20 shown has one connector 21. Therefore, Figure 2 The shown wire breakage inspection device 20 can be connected only to the internal connector 8 manufactured by a specific manufacturing company. Figure 8 The wire breakage inspection device 20 corresponding to the internal connectors 8 of a plurality of manufacturers is shown.

[0049] Figure 8 The wire breakage inspection device 20 shown in the figure has connectors 21A to 21C, an inspection terminal 22, and wirings 23A to 23C. The connector 21A is, for example, Figure 2 and Figure 3 The connector 21A is the same connector as the connector 21 shown. The connector 21A can be attached to and detached from the internal connector 8 manufactured by a specific manufacturing company. The connector 21A is connected to the inspection terminal 22 via the wiring 23A. That is, the connector 21A and the inspection terminal 22 are connected by the wiring 23A.

[0050] The connector 21B has a shape different from that of the connector 21A. The connector 21B can be attached to and detached from the internal connector 8 manufactured by another manufacturer. The connector 21B is connected to the inspection terminal 22 via the wiring 23B. That is, the connector 21B and the inspection terminal 22 are connected by the wiring 23B.

[0051] The connector 21C has a shape different from that of the connector 21A and the connector 21B. The connector 21C can be attached to and detached from the internal connector 8 manufactured by another manufacturer. The connector 21C is connected to the inspection terminal 22 via the wiring 23C. That is, the connector 21C and the inspection terminal 22 are connected by the wiring 23C.

[0052] Figure 8 The example in which the connectors 21A to 21C have nine pins, 1 to 9, respectively, is shown (the pins are not shown). Figure 8 In the example shown, the inspection terminal 22 has a magnet 27 as a second fixing member. The inspection terminal 22 has nine holes 26a, numbered 1 to 9, formed in a main body 26 thereof.

[0053] Wiring 23A extending from hole 26a No. 1 is connected to pin No. 1 of connector 21A. Wiring 23B extending from hole 26a No. 1 is connected to pin No. 1 of connector 21B. Wiring 23C extending from hole 26a No. 1 is connected to pin No. 1 of connector 21C. The same applies to other wirings. That is, wiring 23A extending from hole 26a No. 9 is connected to pin No. 9 of connector 21A. Wiring 23B extending from hole 26a No. 9 is connected to pin No. 9 of connector 21B. Wiring 23C extending from hole 26a No. 9 is connected to pin No. 9 of connector 21C.

[0054] in the case of Figure 8 The wire breakage inspection device 20 shown can be applied to the internal connectors 8 of a plurality of manufacturing companies.

[0055] In this embodiment, an example of performing a disconnection inspection using a circuit meter 13 having a probe-type inspection terminal 14 is described. That is, in the example shown in this embodiment, a hole 26a for inserting the inspection terminal 14 is formed in the main body 26 of the inspection terminal 22. As another example, a disconnection inspection may be performed using a circuit meter 13 having a clamp-type inspection terminal 14.

[0056] In this case, the inspection terminal 22 may include a protrusion, a pin, etc. that can be clamped by the inspection terminal 14. The inspection terminal 22 may include a protrusion, a pin, etc. in addition to the hole 26a.
