Summary of the Invention

Problems to be Solved by the Invention

[0004] When a defect occurs in the system described in Patent Document 1, a maintenance worker goes to the site and performs an operation to eliminate the defect. Since the system described in Patent Document 1 is provided with a door that opens and closes, in this operation, first, a disconnection inspection is performed.

[0005] When performing a disconnection inspection, a circuit tester is used. Conventionally, in order to confirm the presence or absence of a disconnection, a maintenance worker directly connected the terminals of the circuit tester to the connectors provided in the system. For this reason, the connectors provided in the system were sometimes damaged by the terminals of the circuit tester.

[0006] The present disclosure has been made to solve the above-described problems. An object of the present disclosure is to prevent damage to the connectors provided in the security system including an electric lock when performing a disconnection inspection.

[0008] The wire breakage inspection method according to this disclosure is a method for inspecting a wire breakage in a security system comprising: an electric lock provided on a door; a first internal wiring extending from the electric lock; a first internal connector provided on the first internal wiring; a second internal connector connected to the first internal connector; a second internal wiring provided with the second internal connector; and a control device connected to the electric lock via the first and second internal wiring and controlling the electric lock, using a wire breakage inspection device in which the first connector and an inspection terminal are connected by the first wiring. The wire breakage inspection method comprises: a first step of removing the electric lock from the door and bringing the first internal connector and the second internal connector connected to the first internal connector to the outside of the door; a second step of removing the first internal connector from the second internal connector after the first step; a third step of connecting the first connector to the second internal connector after the second step; a fourth step of connecting the inspection terminal of a circuit meter to the inspection terminal; and a fifth step of inspecting a wire breakage by opening and closing the door after the third and fourth steps. [Effects of the Invention]

[0009] According to this disclosure, when inspecting for disconnections in a security system equipped with an electric lock, damage to the connectors provided in the system can be prevented. [Brief explanation of the drawing]

[Figure 5] This is a diagram illustrating the method for inspecting for broken wires. [Figure 6] This is a diagram illustrating the method for inspecting for broken wires. [Figure 7]This is a diagram illustrating the method for inspecting for broken wires. [Figure 8] This figure shows another example of a wire breakage inspection device. [Modes for carrying out the invention]

[0011] A detailed explanation follows, with reference to the drawings. Repetitive explanations will be simplified or omitted as appropriate. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0012] Embodiment 1. Figure 1 shows an example of security system 1. First, security system 1 will be described with reference to Figure 1. Security system 1 comprises a door 2, an electric lock 3, a control device 4, and a reader 5.

[0013] Door 2 is installed in a location where access needs to be controlled. An electric lock 3 is installed inside door 2. An internal connector 7 is installed on internal wiring 6 extending from electric lock 3. An internal connector 8 is connected to internal connector 7. Internal connector 8 is installed at one end of internal wiring 9. Internal wiring 9 is arranged to extend from inside door 2 into the interior of the wall adjacent to door 2. Internal wiring 6, internal connector 7, internal connector 8, and one end of internal wiring 9 are all located inside door 2.

[0014] 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. An 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.

[0015] 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 holds their employee ID card over the card reader. Thereby, 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 transmitted to the control device 4.

[0016] The control device 4 controls the electric lock 3 and the reading device 5. The control device 4 is connected to the electric lock 3 via at least the internal wiring 6 and the internal wiring 9. Other internal connectors and other internal wirings may exist between the electric lock 3 and the control device 4. As an example, if the control device 4 does not receive the identification information read by the reading device 5, the control device 4 locks the door 2 with the electric lock 3. When the identification information read by the reading device 5 matches the pre-registered identification information, the control device 4 controls the electric lock 3 to unlock the door 2.

[0017] In the security system 1, the internal wiring 9 is bent each time the door 2 opens and closes. Therefore, the internal wiring 9 is likely to be disconnected. When a disconnection occurs in the internal wiring 9, the electric lock 3 does not operate normally. When such a problem occurs, the maintenance staff goes to the site and performs work to eliminate the problem. In this work, first, a disconnection inspection is performed. Hereinafter, a disconnection inspection device 20 used when the maintenance staff performs a disconnection inspection will be described.

[0018] FIG. 2 and FIG. 3 are diagrams showing an example of the disconnection inspection device 20 in Embodiment 1. The disconnection inspection device 20 includes a connector 21, an inspection terminal 22, and a wiring 23.

[0019] The connector 21 is detachable from the internal connector 8. As an example, the connector 21 is the same type of connector as the internal connector 7. That is, the connector 21 has the same shape as the shape that the internal connector 7 has. In the examples shown in FIGS. 2 and 3, the connector 21 has a body 24 and nine pins 25. The pins 25 are arranged inside the 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 to which the connector 21 is connected.

[0020] The inspection terminal 22 is a terminal to which the inspection terminal 14 of the circuit meter 13 is connected during the disconnection inspection. As an example, the inspection terminal 22 is the same type of connector as the internal connector 8. That is, the inspection terminal 22 has the same shape as the shape that the internal connector 8 has. In the examples shown in FIGS. 2 and 3, the inspection terminal 22 has a body 26 in which nine holes 26a are formed. Also, the inspection terminal 14 of the circuit meter 13 is a probe. When the disconnection inspection is performed, the inspection terminal 14 is inserted into the holes 26a.

[0021] The wiring 23 connects the connector 21 and the inspection terminal 22. FIGS. 2 and 3 show an example in which the wiring 23 has lines extending from the connector 21 and lines extending from the inspection terminal 22, and these lines are connected by crimping.

[0022] Next, also referring to FIGS. 4 to 7, a method for a maintenance worker to perform a disconnection inspection using the disconnection inspection device 20 in the security system 1 shown in FIG. 1 will be described. FIG. 4 is a flowchart showing the disconnection inspection method in Embodiment 1. FIGS. 5 to 7 are diagrams for explaining the disconnection inspection method.

[0023] The maintenance worker removes the electric lock 3, which is installed inside the door 2, from the door 2 (S101). Specifically, as shown in Figure 5, a cover 15 is provided on the end face 2a of the door 2. The maintenance worker removes the cover 15 from the main body of the door 2. This reveals an opening 2b on the end face 2a of the door 2 that leads to the space where the electric lock 3 is located. The maintenance worker removes the electric lock 3 by operating through the opening 2b and then pulls the removed electric lock 3 out of the door 2 through the opening 2b. Figure 6 shows the state in which the electric lock 3 has been pulled out of the door 2.

[0024] As described above, the internal wiring 6 extends from the electric lock 3. Furthermore, an internal connector 7 is connected to an internal connector 8 provided on the internal wiring 6. Therefore, by pulling the electric lock 3 out of the door 2 through the opening 2b, the internal connectors 7 and 8 are also pulled out of the door 2 through the opening 2b, as shown in Figure 6 (S102). In Figure 6, the state in which the internal connectors 7 and 8 are pulled out of the door 2 is shown by solid lines, and the state before they are pulled out is shown by dashed lines.

[0025] The maintenance worker pulls internal connectors 7 and 8 out of door 2, then disconnects internal connector 7 from internal connector 8 (S103).

[0026] Next, the maintenance worker attaches the wire breakage inspection device 20 to the internal connector 8 from which the internal connector 7 has been removed. Specifically, the maintenance worker connects the connector 21 of the wire breakage 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.

[0027] When connector 21 is connected to internal connector 8 and test terminal 14 is connected to test terminal 22, test terminal 14 is electrically connected to internal wiring 9. Figure 7 shows the state in which test terminal 14 is electrically connected to internal wiring 9. The maintenance worker performs a wire break inspection by opening and closing door 2 in the state shown in Figure 7 (S106).

[0028] A disconnection may only occur when door 2 makes a specific movement or when door 2 is positioned in a specific location. Therefore, in S106, the maintenance worker determines whether or not there is a disconnection while moving door 2. For example, the maintenance worker checks for continuity between the test terminal 22 and the control device 4 by looking at the resistance value displayed on the circuit meter 13 while moving door 2. A buzzer may be emitted from the circuit meter 13 while continuity is detected by the circuit meter 13.

[0029] In the example shown in this embodiment, when a wire break inspection 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 a wire break inspection is performed, the inspection terminal 14 is not directly connected to the internal connector 8. Therefore, accidents such as the hole formed in the internal connector 8 being widened by the inspection terminal 14 during inspection do not occur. In the example shown in this embodiment, when a wire break inspection is performed in a security system 1 equipped with an electric lock 3, damage to the connectors provided in the system 1 can be prevented.

[0030] The following describes other functions that the wire breakage inspection device 20 can employ, and other procedures that the wire breakage inspection method can employ.

[0031] As described above, the maintenance worker performs the wire breakage inspection while moving the door 2. For this reason, it is preferable that the maintenance worker's hands are free when the wire breakage inspection is performed. For this reason, the circuit tester 13 may be provided with a first fixing member for detachably fixing the main body to the door 2. The first fixing member is, for example, a magnet. As another example, the inspection terminal 22 of the wire breakage inspection device 20 may further be provided with a second fixing member for detachably fixing the main body 26 to the door 2. The second fixing member is, for example, a magnet.

[0032] If the circuit meter 13 is equipped with a first fixing member, the maintenance worker fixes the circuit meter 13 to the door 2 before performing the wire breakage inspection in S106. Then, with the circuit meter 13 fixed to the door 2, the maintenance worker moves the door 2 to check for any wire breakage. The step of fixing the circuit meter 13 to the door 2 may be performed before S103. Also, if the inspection terminal 22 is equipped with a second fixing member, the maintenance worker may fix the inspection terminal 22 to the door 2 when fixing the circuit meter 13 to the door 2.

[0033] In case a commercially available circuit meter that does not have a first fixing member is used as the circuit meter 13, the inspection terminal 22 may further be provided with a holding member for holding the circuit meter 13. The holding member is a member for holding the circuit meter 13 in the main body 26 which is fixed to the door 2 by the second fixing member. If the inspection terminal 22 is provided with 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 fix the inspection terminal 22 to the door 2 and then have the holding member hold the circuit meter 13.

[0034] To prevent the inspection terminal 14 from becoming detached from the inspection terminal 22 when the door 2 is opened or closed, the inspection terminal 22 may further be equipped with a holding mechanism to maintain the state in which the inspection terminal 14 is connected.

[0035] Figure 8 shows another example of the wire breakage inspection device 20. The shape of the internal connector 8 provided in the security system 1 varies depending on the manufacturer. The wire breakage inspection device 20 shown in Figure 2 has one connector 21. Therefore, the wire breakage inspection device 20 shown in Figure 2 can only be connected to internal connector 8 from a specific manufacturer. Figure 8 shows the wire breakage inspection device 20 compatible with internal connector 8 from multiple manufacturers.

[0036] The wire breakage inspection device 20 shown in Figure 8 comprises connectors 21A to 21C, an inspection terminal 22, and wiring 23A to 23C. Connector 21A is, for example, the same connector as connector 21 shown in Figures 2 and 3. Connector 21A is detachable from an internal connector 8 manufactured by a specific company. Connector 21A is connected to the inspection terminal 22 by wiring 23A. That is, connector 21A and the inspection terminal 22 are connected by wiring 23A.

[0037] Connector 21B has a different shape from that of connector 21A. Connector 21B is detachable from internal connectors 8 manufactured by other companies. Connector 21B is connected to the test terminal 22 by wiring 23B. That is, connector 21B and the test terminal 22 are connected by wiring 23B.

[0038] Connector 21C has a different shape from that of connector 21A and connector 21B. Connector 21C is detachable from internal connectors 8 manufactured by other companies. Connector 21C is connected to the test terminal 22 by wiring 23C. That is, connector 21C and the test terminal 22 are connected by wiring 23C.

[0039] Figure 8 shows an example in which each of the connectors 21A to 21C has nine pins numbered from 1 to 9 (pins are not shown). In the example shown in Figure 8, the inspection terminal 22 is equipped with a magnet 27 as a second fixing member. The inspection terminal 22 has nine holes 26a formed in the main body 26, numbered from 1 to 9.

[0040] Wire 23A extending from hole 1 26a is connected to pin 1 on connector 21A. Wire 23B extending from hole 1 26a is connected to pin 1 on connector 21B. Wire 23C extending from hole 1 26a is connected to pin 1 on connector 21C. The same applies to the other wires. That is, wire 23A extending from hole 9 26a is connected to pin 9 on connector 21A. Wire 23B extending from hole 9 26a is connected to pin 9 on connector 21B. Wire 23C extending from hole 9 26a is connected to pin 9 on connector 21C.

[0041] The wire breakage inspection device 20 shown in Figure 8 can be applied to internal connectors 8 from multiple manufacturers.

[0042] In this embodiment, an example of performing a wire break inspection using a circuit meter 13 equipped with a probe-type inspection terminal 14 has been 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 wire break inspection may be performed using a circuit meter 13 equipped with a clip-type inspection terminal 14.

[0043] To prepare for such cases, the inspection terminal 22 may be equipped with a projection or pin that can be gripped by the inspection terminal 14. In addition to the hole 26a, the inspection terminal 22 may be equipped with a projection or pin. [Industrial applicability]
