Each of the side surfaces 6a of the windshield cover 6 is formed with an introduction port 6b for introducing the optical fiber to the fusion splicing portion 3 (that is, to each of the optical fiber holders 31).

Next, the configuration of the theft detection system 1 for detecting the theft state of the fusion splicer 10 having such a configuration on the information terminal side will be described with reference to FIG. FIG. 3 is a block diagram showing an outline of a theft detection system for a fusion splicer according to one aspect of the present invention. As shown in FIG. 3, the theft detection system 1 includes a fusion splicing device 10 and an information terminal 20 that can be wirelessly connected to each other. Although FIG. 3 shows an example in which one fusion splicing device 10 is wirelessly connected to one information terminal 20, a plurality of fusion splicing devices 10 are wirelessly connected to one information terminal 20. Alternatively, one or a plurality of fusion splicing devices 10 may be wirelessly connected to a plurality of information terminals 20 .

As shown in FIG. 3, the fusion splicing device 10 functionally includes a wireless communication unit 11, an authentication processing unit 12, a display unit 13, a response processing unit 14, and a lock unit 15, and drives these units. It has a power supply (battery) for As shown in FIG. 4, the fusion splicing device 10 includes hardware such as a CPU 10a, a RAM 10b, a ROM 10c, an input device 10d, a wireless communication module 10e, an auxiliary storage device 10f, and an output device 10g as its control unit. and a computer comprising: Each function of the fusion splicing device 10, which will be described later, is exhibited by operating these components by a program or the like. The fusion splicing device 10 also includes various fusion splicing mechanisms 10h other than the control unit.

The wireless communication unit 11 is a part that performs wireless communication with the information terminal 20 (wireless communication unit 21). The wireless communication unit 11 is composed of, for example, a wireless LAN card or the like, and performs wireless communication with the information terminal 20 in the 2.4 GHz band conforming to IEEE802.11.

The authentication processing unit 12 is a part that performs authentication work such as pairing processing with the information terminal 20 (authentication processing unit 22 ) via the wireless communication units 11 and 21 . The authentication processing unit 12 extracts the pairing information from the signal transmitted from the information terminal 20 as a message signal (for example, a text (TXT) file) including the pairing information and received by the wireless communication unit 11. For example, the pairing information and Acquire 4-digit numeric information. The authentication processing unit 12 passes the acquired four-digit number information to the display unit 13, displays the number on a monitor or the like for a predetermined period of time, and selects "pairing/non-pairing" with the information terminal 20. The selection screen is also displayed by the display unit 13 . Further, when the authentication processing unit 12 receives selection information to the effect that "perform pairing" with the information terminal 20 from the display unit 13, which will be described later, the authentication processing unit 12 generates a message signal to that effect, and performs wireless communication. It is transmitted to the information terminal 20 (the wireless communication unit 21 and the authentication processing unit 22) via the unit 11. FIG.

The display unit 13 includes, for example, the monitor 5 described above, and displays a 4-digit number required for pairing processing with the information terminal 20 and pairing with the information terminal 20 / A selection screen such as no authentication is displayed based on instruction information from the authentication processing unit 12 . The display unit 13 displays the 4-digit number on the monitor 5 or the like based on the 4-digit number of the pairing information acquired by the authentication processing unit 12, and performs "pairing/pairing" with the information terminal 20. "No" selection screen is displayed. When “pairing” with the information terminal 20 is selected, the display unit 13 passes the selection information to the authentication processing unit 12 .

After the pairing process (authentication) with the information terminal 20 is completed, the response processing unit 14 responds to message signals (status confirmation information) sent from the information terminal 20 at predetermined intervals. For example, one acknowledgment signal is returned for one received message to the information terminal 20 via the wireless communication unit 11 at the lower protocol level. It should be noted that the information terminal 20 can calculate the response time (see FIG. 6) of the radio signal, which will be described later, by receiving the acknowledgment signal.

The lock unit 15 is configured to activate the fusion splicing function of the fusion splicing device 10 (fusion splicing mechanism 10h such as fusion of fibers by arc discharge and heating of a fiber reinforcing sleeve) when a predetermined condition is not satisfied. It is the part that locks all or part of it and makes it unusable. For example, as will be described later, the lock unit 15 checks the existence of a message signal wirelessly transmitted from the information terminal 20 at predetermined intervals and the pairing number in the file, and confirms that the message signal has been sent at predetermined intervals. If it is confirmed that there is a pairing number or if the pairing numbers match, a process of deleting the received message signal is performed. On the other hand, when the lock unit 15 performs confirmation processing at a predetermined cycle, if there is no message signal (there was no transmission) or the pairing numbers do not match, the fusion splicing device 10 is put into a stolen state. It determines that there is, and electronically locks all or part of the fusion splicing function of the fusion splicing device 10 . Further, the lock unit 15 may perform such lock processing when the non-existence of the message signal or the mismatch of the pairing numbers occurs consecutively for a specified number of times (for example, three times). This makes it possible to more accurately determine that the fusion splicing device 10 is in a stolen state. Note that the lock unit 15 may also perform automatic notification processing to the police, alarm with a buzzer for crime prevention, etc., when performing such lock processing.

A power supply unit (battery) is housed inside the housing of the fusion splicing device 10 . It is preferable that the power supply section always supplies power to the theft detection system 1 . This allows the theft detection system to always operate without being affected by the usage state of the fusion splicing device 10 (fusion splicing function). Note that the power supply unit may also be used for driving the fusion splicing mechanism. If safety is prioritized, the power supply unit for the theft detection system may be housed in a location that is not easily accessible by the user, and is different from the one that drives the fusion splicing mechanism.

The information terminal 20 includes, for example, a mobile wireless communication terminal such as a smartphone, and includes a wireless communication unit 21, an authentication processing unit 22, a display unit 23, an acquisition unit 24, a determination unit 25, a notification unit 26, a cancellation unit 27, a position An acquisition unit 28 and a distance table 29 are provided. As shown in FIG. 5, the information terminal 20 includes a computer having hardware such as a CPU 20a, a RAM 20b, a ROM 20c, an input device 20d, a wireless communication module 20e, an auxiliary storage device 20f, and an output device 20g. be done. Each function of the information terminal 20, which will be described later, is exhibited by the operation of these components by a program or the like.

The wireless communication unit 21 includes a wireless communication module 20e, and transmits and receives various message signals to and from the wireless communication unit 11 of the fusion splicing device 10 by wireless communication. The wireless communication unit 21 is composed of, for example, a wireless LAN module built into the terminal, and performs communication in the 2.4 GHz band conforming to, for example, IEEE802.11 so as to correspond to the wireless standard of the wireless communication unit 11. . Note that other bands and communication standards may be used as long as wireless communication can be performed with the wireless communication unit 11 .

The authentication processing unit 22 performs authentication work such as pairing processing with the fusion splicing device 10 (authentication processing unit 12). The authentication processing unit 22 causes the display unit 23 to be described later to display a four-digit number, which is pairing information for performing pairing processing with the fusion splicing device 10, and includes the four-digit number. A message signal is transmitted to the fusion splicing device 10 (authentication processing unit 12) via the wireless communication unit 21. FIG. In addition, when the authentication processing unit 22 receives a message signal containing information to the effect of “pairing” from the fusion splicing device 10 (authentication processing unit 12), the fusion splicing device 10 and Complete the pairing process between When the authentication processing unit 22 receives the information to the effect that "perform pairing" from the fusion splicing device 10, the authentication processing unit 22 transmits this information to a management server (not shown) that controls the system including the theft detection system. You can leave it.

The display unit 23 is a part that displays various kinds of information in the information terminal 20 . The display unit 23 displays the four-digit number for pairing generated by the authentication processing unit 22 on the display of the information terminal 20 for a predetermined time (for example, a pairing standby time of 10 seconds). In addition, the display unit 23 displays the interval at which the theft detection system 1 detects whether or not the theft is possible (for example, every minute, every 10 minutes, every hour, or every day) and the total time for which the theft is detected (10 minutes, 1 hour, 1 day, 30 days, etc.) is displayed on the display as a selection screen, and the desired interval and desired total time selected by the operator are transferred to the acquiring unit 24 .

The acquiring unit 24 acquires wireless status data between the fusion splicing device 10 and the information terminal 20 which are wirelessly connected to each other by authentication processing. The acquiring unit 24 acquires, as wireless status data, for example, the radio field strength and communication response time between the fusion splicing device 10 and the information terminal 20 at predetermined intervals (detection intervals described above). The acquisition unit 24 may acquire only the radio wave intensity between the fusion splicing device 10 and the information terminal 20 as the radio status data, or may acquire the radio field strength between the fusion splicing device 10 and the information terminal 20. Only the response time may be obtained, or both the radio field intensity and the response time may be obtained. The wireless status data acquired by the acquiring unit 24 is not limited to the above data, and other wireless status data corresponding to changes in the distance between the fusion splicing device 10 and the information terminal 20 may be used. information may be obtained and used.

The determination unit 25 determines whether or not the fusion splicing device 10 is moving away from the information terminal 20 based on changes in the wireless status data acquired by the acquisition unit 24 . Specifically, the determination unit 25 compares the wireless status data (radio field intensity and/or response time) acquired by the acquisition unit 24 with the distance table 29 (see FIG. 6), and A distance to the information terminal 20 is calculated. In the distance table 29, for example, as shown in FIG. The relationship with the distance between is determined in advance. Note that the distance information and the like described in the distance table 29 may include a predetermined relational expression in advance so as to be finely adjusted according to the radio wave intensity and response time obtained on site.

Further, when the distance calculated by referring to the distance table 29 is larger than the distance calculated before (when there is a change), the determination unit 25 determines the direction in which the fusion splicing device 10 moves away from the information terminal 20 . (see FIG. 7). In this determination, the determination unit 25 determines that the calculated distance is greater than the previously calculated distance for a predetermined number of times (for example, three times) in succession. It may be determined that the object is moving away from the object. In this case, the movement of the fusion splicing device 10 when it is not stolen can be prevented from being erroneously detected as a stolen state.

The notification unit 26 is a part that, when the determination unit 25 determines that the fusion splicing device 10 is moving away from the information terminal 20, performs predetermined notification processing in the information terminal 20 and notifies the operator. . When such a theft state is detected, the notification unit 26 notifies the user by notification means such as sound (buzzer), screen message display, or vibration application. This allows the user holding the information terminal 20 to detect whether the fusion splicing device 10 has been stolen.

The release portion 27 is a portion for releasing the lock when the lock portion 15 of the fusion splicing device 10 has locked the fusion splicing mechanism. Upon receiving an instruction to unlock the fusion splicing device 10 locked under a predetermined condition from the user through input processing, the unlocking unit 27 generates a unlocking signal including the pairing information held by the authentication processing unit 22 . generated, and transmits the release signal to the fusion splicing device 10 via the wireless communication unit 21 . On the fusion splicing device 10 side, upon receiving the release signal, the pairing information included in the release signal is collated. to release the lock process. Thereby, the lock by the lock portion 15 can be released. It should be noted that the functions of the unlocking unit 27 described above may be provided on the server of the integrated system including the theft detection system 1 . In this case as well, the server sends a signal for releasing the lock by the lock unit 15 using the pairing information, which is the authentication information acquired in advance, through any wireless communication means. It can be sent to the device 10 to perform the unlocking process.

When the determination unit 25 determines that the fusion splicing device 10 is moving away from the information terminal 20, or when wireless communication between the fusion splicing device 10 and the information terminal 20 is stopped, the position acquisition unit 28 If it is determined that the connection has been disconnected, it is determined that the fusion splicing device 10 has been stolen, and the location information of the fusion splicing device 10 is acquired. If the fusion splicing device 10 is stolen, a report of the theft, an application for theft insurance, etc. must be made, and the location of the theft must be indicated at that time. Therefore, by having the information terminal 20 acquire such approximate information of the stolen location, it is possible to easily prove the location information at the time of such application. The position acquisition unit 28 includes, for example, GPS, and acquires position information by GPS or the like. The position acquisition unit 28 may be configured to acquire the position information of the fusion splicing device 10 all the time or periodically, and acquire the position information as the specific position information when the determination is made.

Next, pairing processing (authentication processing) in the theft detection system 1 according to this embodiment will be described with reference to FIG. FIG. 8 is a sequence diagram for performing pairing processing between the fusion splicing device 10 and the information terminal 20 in the theft detection system 1. As shown in FIG.

As shown in FIG. 8, in the theft detection system 1, the user first activates an application for the theft detection system on the information terminal 20 side (step S1). In the information terminal 20, when this application is started, a screen for the anti-theft system is displayed, and a four-digit number for pairing is displayed on the screen by the display unit 23 for a predetermined time (for example, 10 seconds as a pairing waiting time). ) is displayed (step S2). The information terminal 20 uses the wireless communication unit 21 to upload (transmit) a message signal (for example, a TXT file) including pairing information for mutual authentication to the fusion splicing device 10 substantially simultaneously with the screen display in step S2. (Step S3). Note that this message signal is not limited to a text file.

Next, on the side of the fusion splicing device 10 that has received the message signal including the pairing information by the wireless communication unit 11, the authentication processing unit 12 extracts the four-digit numerical information for pairing included in the message signal, A four-digit number is displayed on a monitor or the like. In addition, the authentication processing unit 12 of the fusion splicing device 10 displays a selection screen for selecting whether to pair with the information terminal 20 on the monitor. Then, the user of the fusion splicing device 10 (same as the user of the information terminal 20) selects a selection item of pairing/not pairing (step S5). When the authentication processing unit 12 accepts the selection to perform pairing, the fusion splicing device 10 generates a message signal (pairing selection result information) to perform pairing, and the wireless communication unit 11 to the information terminal 20 (step S6). When the fusion splicing device 10 accepts a selection not to perform pairing, the authentication processing unit 12 terminates the process (step S7).

Next, the information terminal 20 that has received the pairing information (pairing selection result information) uses the acquisition unit 24 to set a predetermined cycle for detecting theft, radio wave intensity, response time, and the like. For example, the information terminal 20 uses the display unit 23 to detect whether or not the theft is possible at intervals (for example, every minute, 10 minutes, hourly, or daily) at which the theft detection system 1 detects whether or not theft is possible. The total time (10 minutes, 1 hour, 1 day, 30 days, etc.) is displayed on the display as a selection screen, and the desired interval and total time selected by the worker are set by the acquisition unit 24 . The information terminal 20 also transmits information (pairing setting information) such as the desired interval and total time to the paired fusion splicing device 10 (step S9). The information terminal 20 may transmit the pairing information (pairing selection result information) received from the fusion splicing device 10 to the management server that controls the entire system (step S8). In step S8, after setting the detection interval, the total time, and the like, these pieces of information (pairing selection result information, pairing setting information) may be transmitted to the management server. With the above processing, theft detection by the theft detection system 1 is started.

Next, a method for detecting theft of the paired fusion splicing device 10 by the information terminal 20 will be described with reference to FIG. FIG. 9 is a flow chart showing a method of theft detection in the theft detection system 1. As shown in FIG.

As shown in FIG. 9, the paired fusion splicing device 10 and the information terminal 20 are arranged within 1 m. The radio wave intensity is measured by the acquiring unit 24 (step S11). In this embodiment, for example, the radio wave intensity at this time is assumed to be -40 dBm.

Subsequently, the information terminal 20 determines whether or not a predetermined time (for example, one hour) has elapsed since the theft detection process was started, using the acquisition unit 24 (step S12). If the predetermined time has elapsed as a result of the determination of the passage of the predetermined time in step S12, the information terminal 20 causes the acquisition unit 24 to measure again the radio wave intensity between the fusion splicing device 10 and the information terminal 20 . The determination unit 25 of the information terminal 20 compares the measured radio wave intensity with the distance table 29 and calculates the distance between the fusion splicing device 10 and the information terminal 20 . If this distance is greater than the distance based on the previously measured radio wave intensity, then the process proceeds to step S15.

In the information terminal 20, in the determination in step S14, the distance between the fusion splicing device 10 and the information terminal 20 calculated based on the measured radio wave intensity and the distance table 29 was measured before. If it is determined that the distance is greater than the distance based on the radio wave intensity a predetermined number of times (for example, three times in a row) (step S15), the determining unit 25 moves the fusion splicing device 10 away from the information terminal 20. It is detected that the fusion splicing device 10 is in a stolen state (step S16). Then, when the information terminal 20 detects that the fusion splicing device 10 is stolen, it performs notification processing such as a buzzer, and leaves it to the user (step S17). The user can know that the fusion splicing device 10 has stolen information by such notification. In addition, when such information can be transmitted to the fusion splicing device 10 in such a stolen state (when the radio has not been disconnected yet), the fusion splicing device 10 moves away from the information terminal 20. A signal indicating that the fusion splicing device 10 is moving may be transmitted to perform locking by the locking unit 15 of the fusion splicing device 10 . Further, in the above example, the method of determining theft detection is shown by taking the radio wave intensity as an example, but the same applies to the case of detecting theft using the response time shown in FIG.

Next, lock processing of the fusion splicing mechanism in the fusion splicing device 10 will be described with reference to FIG. Part or all of the sequence shown in FIG. 10 may substantially overlap with the theft detection flow shown in FIG. 9, but may be performed separately.

First, after a predetermined detection interval has elapsed (step S21), the information terminal 20 transmits a message signal (status confirmation information) (for example, a TXT file) indicating whether or not the fusion splicing device 10 has been stolen. is transmitted (uploaded) to (step S22). This signal contains pairing information including a pairing number. Note that this message signal is not limited to a text file.

Subsequently, the fusion splicer 10 that has received this extracts the pairing number from the signal, and the lock section 15 confirms the pairing number in the file (step S23). Then, when the pairing number matches the number stored in advance in its own device, the lock section 15 deletes the received message signal (status confirmation information) (step S24). If the pairing numbers do not match in step S24, the process returns to step S23. In the fusion splicer 10, this confirmation work is performed at a predetermined cycle, and whether the pairing number does not match or the message signal from the information terminal 20 is not received (non-confirmed) for a predetermined number of times. Confirm whether or not (step S25).

Subsequently, in the fusion splicing device 10, the lock unit 15 determines in step S25 that the pairing numbers do not match or the message signal from the information terminal 20 has not been received (unconfirmed) for a predetermined number of times. If so, it is determined that the fusion splicing device 10 is in a stolen state, and the process proceeds to step S26 to lock the fusion splicing function of the fusion splicing device 10 (step S26). Thereby, if the fusion splicing device 10 is stolen, its use can be disabled.

As described above, the theft detection system 1 according to the present invention detects that the fusion splicing device 10 is moving away from the position of the information terminal 20 that can be carried by the user at all times. Since the fact can be easily notified to the user, the theft of the fusion splicing device 10 can be deterred.

The theft detection system 1 also includes a distance table 29 that defines in advance the relationship between wireless status data between the fusion splicing device 10 and the information terminal 20 and the distance between the fusion splicing device 10 and the information terminal 20. The determination unit 25 compares the wireless status data acquired by the acquisition unit 24 with the distance table 29 to calculate the distance between the fusion splicing device 10 and the information terminal 20, and the calculated distance If the distance is greater than the previously calculated distance, it is determined that the fusion splicing device 10 is moving away from the information terminal 20 . Therefore, according to the theft detection system 1, since the movement of the fusion splicing device 10 is determined using the predetermined distance table 29, it is possible to simplify the determination process.

In the theft detection system 1 , the acquisition unit 24 acquires wireless status data including radio field strength and wireless communication response time between the fusion splicing device 10 and the information terminal 20 . For this reason, according to the theft detection system 1, fusion splicing is performed using information related to the wireless device that is often provided for adding other functions (for example, general data management of the fusion splicing device, etc.). Since unauthorized movement of the device 10 is determined, it is possible to provide the fusion splicing device 10 with a new function such as anti-theft without adding new parts or with a reduced number of new parts.

In addition, in the theft detection system 1, the acquisition unit 24 continuously acquires wireless status data at a predetermined cycle. Since wireless status data is continuously acquired at predetermined intervals in this manner, it is possible to continuously detect that the fusion splicing device 10 is moving away from the information terminal 20, thereby preventing fusion splicing other than theft. By excluding the movement of the splicing device 10 from the determination, the theft determination of the fusion splicing device 10 can be made more reliable, and theft can be further deterred.

Further, the theft detection system 1 detects that the fusion splicing device 10 is moving away from the information terminal 20 , or the wireless communication between the fusion splicing device 10 and the information terminal 20 is detected. The fusion splicing device 10 further includes a locking unit 15 that locks the function of the fusion splicing device when it is determined that the communication has been disconnected. According to the theft detection system 1, even if the information terminal 20 is stolen, the information terminal 20 is locked (disabling process). Therefore, theft of the fusion splicing device 10 can be further prevented. In this case, the theft detection system 1 may further include an unlocking section 27 that unlocks the locking section 15 . By providing such a releasing means, even if the fusion splicing device 10 is locked, the lock can be released and the fusion splicing device 10 can be unlocked by following an appropriate recovery procedure by an authorized user. The connection device 10 can be used again. Note that such a release unit may be provided on the server side that acquires the authentication information performed by the authentication processing unit 22, and the server sends a signal to release the lock by the lock unit 15 using the authentication information. It may be transmitted to the fusion splicing device 10 . Similar effects can be obtained in this case as well.

The theft detection system 1 further includes a position acquisition unit 28 that acquires position information of the fusion splicing device 10 . Therefore, even in the event of a theft, the information terminal 20 can accumulate the location information regarding the stolen position in the theft report or theft insurance. can be simplified. Regarding the position information, when the determination unit 25 determines that the fusion splicing device 10 is moving away from the information terminal 20, or when wireless communication between the fusion splicing device 10 and the information terminal 20 is The location information may be acquired when it is determined that the connection has been disconnected, or the location information may be acquired, stored, and updated periodically at predetermined time intervals, and the latest location information acquired when it is determined as described above. You can save it.
