Description

Wire disconnection inspection device and wire disconnection inspection method

[0001] The present disclosure relates to a wire disconnection inspection device and a wire disconnection inspection method.

[0002] A system equipped with an electric lock is described in Patent Document 1. In the system described in Patent Document 1, if the electric lock does not unlock even when an unlock command is output from a card reader, a malfunction of the electric lock is detected.

[0003] Japanese Patent Publication No. 1-127774

[0004] When a malfunction occurs in the system described in Patent Document 1, a maintenance worker goes to the site and performs work to resolve the malfunction. Because the system described in Patent Document 1 is equipped with a door that opens and closes, the work first involves checking for broken wires.

[0005] A circuit tester is used to check for broken wires. Conventionally, maintenance personnel would connect the terminals of the circuit tester directly to the connector on the system to check for broken wires. This could result in the connector on the system being damaged by the terminals of the circuit tester.

[0006] The present disclosure has been made to solve the above-mentioned problems, and an object of the present disclosure is to provide a break inspection device and a break inspection method that can prevent damage to connectors provided in a security system equipped with an electric lock when inspecting for breaks in the system.

[0007] The present disclosure provides a wire break inspection device for inspecting wire breaks in a security system including an electric lock installed in a door, a first internal wiring extending from the electric lock, a first internal connector installed in the first internal wiring, a second internal connector connected to the first internal connector, the second internal wiring equipped with the second internal connector, and a control device connected to the electric lock via the first internal wiring and the second internal wiring and controlling the electric lock. The wire break inspection device includes a first connector detachably attached to the second internal connector, a test terminal to which a test terminal of a circuit meter is connected, and a first wiring connecting the first connector and the test terminal. When the first connector is connected to the second internal connector and the test terminal is connected to the test terminal, the test terminal and the second internal wiring are electrically connected.

[0008] A wire break inspection method according to the present disclosure is a method for inspecting a wire break in a security system including an electric lock provided in 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, the second internal wiring provided with the second internal connector, and a control device connected to the electric lock via the first internal wiring and controlling the electric lock using a wire break inspection device in which the first connector and an inspection terminal are connected by the first wiring. The wire break inspection method includes 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 disconnecting 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 an inspection terminal of a circuit meter to the inspection terminal, and a fifth step of inspecting for a wire break by opening and closing the door after the third and fourth steps.

[0009] According to the present disclosure, when inspecting for disconnections in a security system equipped with an electric lock, damage to the connectors equipped in the system can be prevented.

[0010] Fig. 1 is a diagram showing an example of a security system. Fig. 2 is a diagram showing an example of a wire disconnection inspection device in embodiment 1. Fig. 3 is a diagram showing an example of a wire disconnection inspection device in embodiment 1. Fig. 4 is a flowchart showing a wire disconnection inspection method in embodiment 1. Fig. 5 is a diagram for explaining the wire disconnection inspection method. Fig. 6 is a diagram for explaining the wire disconnection inspection method. Fig. 7 is a diagram showing another example of a wire disconnection inspection device.

[0011] The following detailed description will be given with reference to the drawings. Duplicate descriptions will be simplified or omitted as appropriate. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0012] Embodiment 1 Fig. 1 is a diagram showing an example of a security system 1. First, the security system 1 will be described with reference to Fig. 1. The security system 1 includes a door 2, an electric lock 3, a control device 4, and a reading device 5.

[0013] Door 2 is installed in a location where passage needs to be controlled. Electric lock 3 is installed inside door 2. Internal wiring 6 extending from electric lock 3 is provided with internal connector 7. 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 to the inside of a wall adjacent to door 2. Internal wiring 6, internal connector 7, internal connector 8, and one end of internal wiring 9 are arranged 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 embedded in a card such as an employee ID card. For example, a user of the system holds their employee ID card over the card reader. This causes the card reader to read the identification information from the tag embedded in the employee ID card. The identification information read by the card reader is sent 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 wiring may exist between the electric lock 3 and the control device 4. As an example, the control device 4 locks the door 2 with the electric lock 3 unless the reading device 5 reads the identification information. If the identification information read by the reading device 5 matches the 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 is opened or closed. For this reason, the internal wiring 9 is prone to breakage. If a break occurs in the internal wiring 9, the electric lock 3 will not operate normally. When such a malfunction occurs, a maintenance person will go to the site and perform work to resolve the malfunction. In this work, first, a wire break inspection is performed. Below, we will explain the wire break inspection device 20 used by the maintenance person when inspecting for a wire break.

[0018] 2 and 3 are diagrams showing an example of the wire disconnection inspection device 20 according to the embodiment 1. The wire disconnection inspection device 20 includes a connector 21, an inspection terminal 22, and a wire 23.

[0019] The connector 21 is detachably attached to 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 internal connector 7. In the example shown in FIGS. 2 and 3 , the connector 21 has a main body 24 and nine pins 25. The pins 25 are arranged inside the main body 24. When the connector 21 has 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 testing terminal 22 is a terminal to which the testing terminal 14 of the circuit meter 13 is connected when testing for a disconnection. As an example, the testing terminal 22 is the same type of connector as the internal connector 8. That is, the testing terminal 22 has the same shape as the internal connector 8. In the example shown in FIGS. 2 and 3 , the testing terminal 22 has a body 26 in which nine holes 26 a are formed. Furthermore, the testing terminal 14 of the circuit meter 13 is a probe. When testing for a disconnection, the testing terminal 14 is inserted into the holes 26 a.

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

[0022] Next, a method for a maintenance worker to inspect for a disconnection using the disconnection inspection device 20 in the security system 1 shown in Fig. 1 will be described with reference to Fig. 4 to Fig. 7. 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 provided inside the door 2 from the door 2 (S101). Specifically, as shown in Fig. 5 , 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. This causes an opening 2b to appear on the end surface 2a of the door 2, which leads to the space where the electric lock 3 is located. The maintenance worker removes the electric lock 3 by operating it through the opening 2b, and then pulls the removed electric lock 3 out of the door 2 through the opening 2b. Fig. 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. The internal connector 8 is connected to the internal connector 7 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 (S102), as shown in Fig. 6. In Fig. 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 person pulls out the internal connector 7 and the internal connector 8 from the door 2, and then disconnects the internal connector 7 from the internal connector 8 (S103).

[0026] Next, the maintenance technician attaches the wire disconnection inspection device 20 to the internal connector 8 from which the internal connector 7 has been removed. Specifically, the maintenance technician connects the connector 21 of the wire disconnection inspection device 20 to the internal connector 8 (S104). Next, the maintenance technician 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 technician connects the inspection terminal 14 to the inspection terminal 22 by inserting the inspection terminal 14 into the hole 26a.

[0027] When the connector 21 is connected to the internal connector 8 and the inspection terminal 14 is connected to the inspection terminal 22, the inspection terminal 14 is electrically connected to the internal wiring 9. Fig. 7 shows a state in which the inspection terminal 14 is electrically connected to the internal wiring 9. The maintenance worker opens and closes the door 2 in the state shown in Fig. 7 to inspect for disconnections (S106).

[0028] A disconnection may occur only when the door 2 moves in a specific way or when the door 2 is placed in a specific position. For this reason, in S106, the maintenance person determines whether or not there is a disconnection while moving the door 2. For example, the maintenance person checks the resistance value displayed on the circuit meter 13 while moving the door 2 to confirm the continuity between the inspection terminal 22 and the control device 4. While the circuit meter 13 detects continuity, the circuit meter 13 may emit a buzzer.

[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, an accident such as the inspection terminal 14 widening a hole formed in the internal connector 8 during inspection does 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 connector equipped in the system 1 can be prevented.

[0030] Other functions that can be employed by the present wire disconnection inspection device 20 and other procedures that can be employed by the present wire disconnection inspection method will be described below.

[0031] As described above, the maintenance person inspects for open circuits while moving the door 2. For this reason, it is preferable that the maintenance person have both hands free when inspecting for open circuits. For this reason, the circuit meter 13 may be provided with a first fixing member for detachably fixing the main body 26 to the door 2. The first fixing member is, for example, a magnet. As another example, the inspection terminal 22 of the open circuit 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 person fixes the circuit meter 13 to the door 2 before inspecting for a broken wire in S106. Then, with the circuit meter 13 fixed to the door 2, the maintenance person moves the door 2 and checks for a broken wire. The step of fixing the circuit meter 13 to the door 2 may be performed before S103. Furthermore, if the inspection terminal 22 is equipped with a second fixing member, the maintenance person may fix the inspection terminal 22 to the door 2 when fixing the circuit meter 13 to the door 2.

[0033] In preparation for the case where a commercially available circuit meter that does not have a first fixing member is used as the circuit meter 13, the testing 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 in the main body 26 that is fixed to the door 2 by the second fixing member. If the testing 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 person can fix the testing terminal 22 to the door 2 and then have the holding member hold the circuit meter 13.

[0034] In order to prevent the inspection terminal 14 from coming off 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 in a connected state.

[0035] Fig. 8 is a diagram showing another example of the disconnection inspection device 20. The shape of the internal connector 8 provided in the security system 1 varies depending on the manufacturer. The disconnection inspection device 20 shown in Fig. 2 has one connector 21. Therefore, the disconnection inspection device 20 shown in Fig. 2 can only be connected to internal connectors 8 made by a specific manufacturer. Fig. 8 shows a disconnection inspection device 20 that is compatible with internal connectors 8 from multiple manufacturers.

[0036] The wire disconnection inspection device 20 shown in Fig. 8 includes connectors 21A to 21C, an inspection terminal 22, and wires 23A to 23C. The connector 21A is the same as the connector 21 shown in Figs. 2 and 3, for example. The connector 21A is detachable from an internal connector 8 made by a specific manufacturer. The connector 21A is connected to the inspection terminal 22 by wire 23A. That is, the connector 21A and the inspection terminal 22 are connected by wire 23A.

[0037] The connector 21B has a shape different from that of the connector 21A. The connector 21B is detachable from an internal connector 8 made by another manufacturer. The connector 21B is connected to the inspection terminal 22 by a wire 23B. That is, the connector 21B and the inspection terminal 22 are connected by the wire 23B.

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

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

[0040] Wire 23A extending from hole 26a No. 1 is connected to pin No. 1 provided on connector 21A. Wire 23B extending from hole 26a No. 1 is connected to pin No. 1 provided on connector 21B. Wire 23C extending from hole 26a No. 1 is connected to pin No. 1 provided on connector 21C. The same applies to the other wires. That is, wire 23A extending from hole 26a No. 9 is connected to pin No. 9 provided on connector 21A. Wire 23B extending from hole 26a No. 9 is connected to pin No. 9 provided on connector 21B. Wire 23C extending from hole 26a No. 9 is connected to pin No. 9 provided on connector 21C.

[0041] The disconnection inspection device 20 shown in FIG. 8 can be applied to internal connectors 8 of a plurality of manufacturers.

[0042] In the present embodiment, an example has been described in which a circuit meter 13 equipped with probe-type inspection terminals 14 is used to inspect for open circuits. That is, in the example shown in the present embodiment, holes 26a for inserting inspection terminals 14 are formed in body 26 of inspection terminal 22. As another example, a circuit meter 13 equipped with clip-type inspection terminals 14 may be used to inspect for open circuits.

[0043] To prepare for such a case, the inspection terminal 22 may be provided with a protrusion or a pin or the like that can be clamped by the inspection terminal 14. The inspection terminal 22 may be provided with a protrusion or a pin or the like in addition to the hole 26a.
