  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a configuration diagram showing an outline of a telephone system of the present invention. The telephone system 1 has a security monitoring function for reporting when an abnormality occurs in a predetermined monitoring target in addition to a normal voice call function, and a plurality of sensors for detecting an abnormality in the predetermined monitoring target (First sensor 2, second sensor 3, third sensor 4) and a plurality of monitoring telephones (first sensors) that perform a monitoring operation based on a voice call with a monitoring source when an abnormality is detected in sensors 2 to 4 Telephone 5, second telephone 6, third telephone 7), a plurality of alarm telephones (fourth telephone 8, fifth telephone 9) that issue an alarm when an abnormality is detected in sensors 2 to 4, and sensors A plurality of notification telephones (sixth telephone set 10 and seventh telephone set 11) that notify the occurrence of an abnormality upon detection of abnormalities 2 to 4, these sensors 2 to 4, monitoring telephones 5 to 7, alarms Telephones 8 and 9 and reporting telephone 1 Mainly comprising a private branch exchange 12 11 are respectively connected (also referred to as key telephone system).

  Sensors (abnormality detection means) 2 to 4 are provided in the vicinity of predetermined monitoring targets (people, things, places, etc.) and connected to the private branch exchange 12 via a sensor I / F (interface) 28 for monitoring. When an abnormality occurs in the target, an abnormality occurrence signal is sent to the private branch exchange 12. For example, various sensors such as a human sensor and a temperature sensor can be used as the sensors 2 to 4, but the sensors 2 to 4 are not necessarily limited to dedicated devices originally intended to detect the amount of change in the monitoring target. Instead, it may be a device such as a microphone or a video camera that can perform the same function by acquiring information about the monitoring target and appropriately processing it.

  The monitoring telephones 5 to 7 are extension telephones (button telephones) provided near the monitoring target corresponding to the sensors 2 to 4 and connected to the extension side of the private branch exchange 12. When the abnormality of the sensors 2 to 4 is detected, the monitoring telephones 5 to 7 execute a monitoring operation based on a voice call by being connected to any one of the reporting telephones 10 and 11 (monitoring source) so that two-way communication is possible. . The monitoring telephones 5 to 7 have a microphone and a speaker (not shown), and are provided with a so-called hands-free function that enables a telephone call without using a handset. This hands-free function can be executed according to a request from the private branch exchange 12 when making a two-way call with the notification telephones 10 and 11. At this time, the monitoring telephones 5 to 7 send the sound collected by their own microphones to the notification telephones 10 and 11, and the user who uses the notification telephones 10 and 11 can monitor the surrounding state of the monitoring target. On the other hand, the voice sent from the notification telephones 10 and 11 (for example, the voice of the user or the alarm sound generated by the notification telephone) is reproduced on the speaker, Intimidation against intruders can be performed.

  The alarm telephones 8 and 9 are extension telephones (button telephones) connected to the extension side of the private branch exchange 12. When an abnormality is detected in the sensors 2 to 4, the alarm telephones 8 and 9 execute an alarm operation for generating an alarm sound from a speaker (not shown) according to a ringing instruction from the private branch exchange 12. This alarm operation can be executed by ringing an incoming call using a hands-free function similar to that of the monitoring telephones 5 to 7 described above. The alarm telephones 8 and 9 have an alarm sound selection function for changing the type of alarm sound depending on which sensor detects an abnormality. The selection of the alarm sound can be performed based on the sensor information (identification information) obtained by detecting the abnormality when the ringing instruction is issued from the private branch exchange 12.

  1 shows an example in which the monitoring telephones 5 to 7 and the alarm telephones 8 and 9 are provided separately for convenience of explanation, it is not always necessary to distinguish between the monitoring telephone and the alarm telephone. Instead of these telephones 5 to 9, it is possible to provide telephones that perform both functions.

  The notification telephones (external telephones) 10 and 11 are external telephones connected to the external line side of the private branch exchange 12 via a PSTN (public network) 13. When the abnormality is detected in the sensors 2 to 4 in the private branch exchange 12 in advance, Information such as a telephone number is registered as a report destination. The user of the telephone system 1 uses the notification telephones 10 and 11 to quickly recognize the occurrence of an abnormality in the monitoring target even in a remote place such as a place to go and confirm the surrounding situation of the monitoring target by voice. Thus, it is possible to perform appropriate measures such as warning a person around the monitoring target. It is not always necessary to call the external telephone when the abnormality of the sensors 2 to 4 is detected. It is also possible to use an extension telephone similar to the monitoring telephones 5 to 7 and the alarm telephones 8 and 9 described above. .

  The private branch exchange 12 includes a communication path switch 21, an external line I / F 22, an internal line I / F 23, a voice guidance transmission unit 24, a PB (Push Button) signal detection unit 25, a central control device 26, a storage device 27, and a sensor I / F 28. I have.

  The communication path switch 21 performs an exchange process in accordance with a request from the central control unit 26 to thereby connect an external telephone (telephones 10 and 11) connected via the external line I / F 22 and an internal line connected via the extension I / F 23. A communication connection path with the telephones (telephones 5 to 9) and a communication connection path between the extension telephones are formed.

  The voice guidance sending unit 24 is connected to an outside line through the communication path switch 21 according to a request from the central control device 26 when an abnormality is detected in the sensors 2 to 4, and provides voice guidance for notifying the detection of the abnormality of the sensors 2 to 4. This is sent to the notification telephones 10 and 11. This voice guidance can notify, for example, the names (identification numbers) of sensors 2 to 4 and monitoring target names (installation positions) based on voice data prepared in advance or voice data generated by voice synthesis.

  The PB signal detection unit 25 receives the push signal from the external telephone or the internal telephone, analyzes the content, and sends the analysis result to the central control device as predetermined data. Although details will be described later, the PB signal detection unit 25, when the notification unit 34 notifies the notification telephones 10 and 11 when the abnormality of the sensors 2 to 4 is detected, It is possible to receive a push signal (connection request signal) transmitted based on a dial input operation performed by the user to request connection with the monitoring telephones 5 to 7.

  The central control unit 26 controls the operation of each part of the private branch exchange 12 in order to realize the voice call function and the security monitoring function of the telephone system 1, and controls operations such as calling, incoming calls, and calls. A call control unit 31, a sensor detection signal reception unit 32, an alarm unit 33, a notification unit 34, and a connection control unit 35. The central control device 26 receives abnormality detection signals output from the sensors 2 to 4 connected to the sensor I / F 28 via the control line 37 and transmits and receives various control signals necessary for the exchange operation of the private branch exchange 12. Can be performed via the control line 37.

  The sensor detection signal receiving unit 32 receives an abnormality detection signal output from the sensors 2 to 4 when an abnormality of the sensors 2 to 4 is detected.

  When the sensor detection signal receiving unit 32 receives an abnormality detection signal from any of the sensors 2 to 4, the alarm unit 33 instructs the alarm ringing by executing a call to the alarm telephones 9 and 10.

  When the sensor detection signal receiving unit 32 receives an abnormality detection signal from any one of the sensors 2 to 4, the reporting unit (reporting unit) 34 calls the reporting telephones 10 and 11 set in advance as the reporting destination. When either of the notification telephones 10 and 11 responds to an incoming call, the voice guidance sending unit 24 executes voice guidance to notify the user who uses the notification telephone that has made the incoming call notification of the occurrence of an abnormality.

  After the reporting unit 34 reports the occurrence of an abnormality to the reporting phone, the connection control unit (connecting means) 35 includes a reporting phone that has performed the reporting and a monitoring phone that corresponds to the sensor that has detected the abnormality. Connect so that two-way communication is possible.

  Here, the connection control unit 35 can execute two connection modes (“automatic” and “dial input”). In the “automatic” connection mode, after the reporting unit 34 reports the occurrence of an abnormality to the reporting telephone, the monitoring telephone corresponding to the sensor that detected the abnormality is independent of the user's operation on the reporting telephone. A connection is made by making a call. On the other hand, in the “dial input” connection mode, after the reporting unit 34 notifies the reporting telephone of the occurrence of an abnormality, the connection is executed according to the user's dial input operation on the reporting telephone. That is, when the PB signal detection unit 25 receives the push signal sent from the notification telephone in response to the user's dial input operation, the connection control unit 35 acquires the analysis result of the push signal from the PB signal detection unit 25. Whether or not the connection is possible is determined by temporarily storing it in a memory (not shown) and comparing it with preset data. Here, both the notification telephone and the monitoring telephone when a push signal (for example, a four-digit number string) generated by a user's dial input operation on the notification telephone matches the collation data set in advance. Two way call is realized.

  Note that the connection control unit 35 requests the monitoring telephone to start a hands-free function when connecting the reporting telephone and the monitoring telephone, and enables a monitoring operation based on a voice call.

  The storage device 27 is a memory that stores various types of information necessary for the operation of the private branch exchange 12, and includes a flash memory, a hard disk drive, and the like. The storage device 27 stores a correspondence information table 38 including information associating the sensors 2 to 4 with the monitoring telephones 5 to 7, and the connection control unit 35 includes a notification telephone and a monitoring telephone. When connecting to a telephone so that two-way communication is possible, it is possible to select a monitoring telephone to be connected to the notification telephone by referring to the correspondence information table 38. FIG. 2 is a diagram illustrating an example of such a correspondence information table. Here, no. 1 to 3 correspond to the connection modes set for the monitoring telephones 5 to 7, the alarm telephones 8 and 9, the reporting telephones 10 and 11, and the reporting telephones 10 and 11 for the sensors 2 to 4, respectively. Is shown.

  For example, for the first sensor (sensor (1)) 2, when the first sensor 2 detects an abnormality, the corresponding first telephone (telephone (1)) 5 performs a monitoring operation, The fourth telephone (telephone (4)) 8 and the fifth telephone (telephone (5)) 9 perform an alarm operation, and the sixth telephone (telephone (6)) 10 and the seventh telephone (telephone) (7)) The occurrence of an abnormality is reported to 11. The connection modes for the sixth telephone set 10 and the seventh telephone set 11 are both set to the “automatic” connection mode.

  Note that the configuration of the monitoring telephone, the alarm telephone, the notification telephone, and the connection mode corresponding to each of the sensors 2 to 4 can be variously changed as desired. For example, a configuration is possible in which a monitoring telephone corresponding to the first sensor 2 is overlapped with a monitoring telephone corresponding to the second sensor 3. Further, the alarm operation can be omitted without setting the alarm telephone. Furthermore, it is also possible to set priorities for the notification telephones in advance and sequentially perform notification operations in accordance with the priorities.

  Next, the operation of the private branch exchange 12 when executing the security monitoring function in the telephone system 1 having the above configuration will be described.

  FIG. 3 is a flowchart showing the security monitoring operation of the private branch exchange shown in FIG. First, when an abnormality occurs in the monitoring target (for example, an intruder is detected) and the sensor detection signal receiving unit 32 receives an abnormality detection signal from any of the sensors 2 to 4 (S101), the alarm unit 33 responds. Based on the information table 38 (see FIG. 2), a ringing instruction is issued to all corresponding alarm telephones (S102). Receiving this ringing instruction, the alarm telephones each emit a warning sound by ringing. In this case, for example, the alarm telephone can be arranged near the monitoring target to threaten an intruder or the like, or can be arranged at a place where a guard or the like resides to notify the occurrence of an abnormality.

  Subsequently, any of the corresponding notification telephones (report destinations) in the correspondence information table 38 has already received a report based on the detection of an abnormality of another sensor and is connected to another monitoring telephone (i.e., It is determined whether or not the monitoring target of another sensor is already being monitored (S103). Therefore, when there is a notification phone that is already connected to another monitoring phone (S103: YES), the voice guidance sending unit 24 provides information on the sensor that has newly detected an abnormality to the notification phone. Voice guidance is provided (S104). Next, the connection control unit 35 switches the notification telephone to a call connection with a monitoring telephone (new monitoring destination) corresponding to the sensor that has newly detected an abnormality, and connects the communication telephone so that two-way communication is possible (S105). . At this time, the connection control unit 35 requests the monitoring telephone to start the hands-free function.

  In S103, if the notification telephone is not already monitoring another monitoring target (S103: NO), the occurrence of abnormality is simultaneously notified to all corresponding notification telephones (report destinations) in the correspondence information table 38. For this purpose is executed (S106).

  Therefore, if there is an incoming call response from any of the notification telephones within a certain time (S107: YES), the state of waiting for a dial input operation from the user using the telephone that responds (that is, waiting for reception of a push signal) (S108). At this time, when the user's dial input operation is performed within a predetermined time and the PB signal detection unit 25 receives an appropriate push signal (S108: YES), the notification telephone is set as a monitoring source, and other notifications are made. The telephone call is stopped (S109). Therefore, the voice guidance sending unit 24 provides voice guidance to the telephone set as the monitoring source with information about the sensor that has detected the abnormality (S110). Subsequently, the connection control unit 35 calls the monitoring telephone corresponding to the sensor that has detected the abnormality, and connects to the telephone set as the monitoring source so that two-way communication is possible (S111). At this time, the connection control unit 35 requests the monitoring telephone to start the hands-free function.

  As a result, the sound collected by the microphone of the monitoring telephone is sent to the monitoring source telephone, and the user who uses the monitoring source telephone can monitor the surrounding condition of the monitoring target, while being transmitted from the monitoring source telephone. The reproduced sound is reproduced by a speaker, and it becomes possible to warn a person existing in the vicinity of the monitoring target, threaten an intruder, and the like.

  On the other hand, in S107, if there is no incoming call response from any of the notification telephones within a predetermined time, the calling of all the notification telephones is stopped (S112), and error processing such as recording an error log is executed (S113). ).

  If the user's dial input operation is not performed in S108, the call connection with the notification telephone is disconnected (S114), and error processing such as recording an error log is executed (S113). By the error processing, the user who uses the telephone set as the monitoring source can appropriately grasp the latest abnormality situation, and can appropriately take measures such as an alarm for the abnormality.

  Although the case where the connection mode of the notification telephone is the “dial input” connection mode is shown here, the operation of S108 is omitted in the case of the “automatic” connection mode.

  In addition, here, it is assumed that a call for notifying the occurrence of an abnormality is simultaneously performed for all the notification telephones registered in the correspondence information table (see FIG. 2). Priorities may be registered, a call may be made based on the priorities, and a notification destination of the next priority may be called when a call destination cannot be connected.

  Next, the operation when the telephone system 1 executes the security monitoring function will be described.

  FIG. 4 is a sequence diagram showing a first security monitoring procedure in the telephone system shown in FIG. Here, the first sensor 2 for detecting an abnormality is assumed to have the correspondence shown in FIG. 2 for the monitoring telephone and the like, and the connection between the notification telephone and the monitoring telephone is executed in the “automatic” connection mode. The The detailed operations in the following procedures are the same as those described with reference to FIG. 1 or FIG.

  First, when the first sensor 2 detects an abnormality to be monitored (S201), an abnormality detection signal is sent to the private branch exchange 12 to notify the abnormality detection (S202). Therefore, the private branch exchange 12 sends a ringing instruction to the fourth telephone 8 and the fifth telephone 9 (alarm telephone) (S203). The fourth telephone set 8 and the fifth telephone set 9 that have received this ringing instruction each emit an alarm sound by ringing ringing (S204, S205).

  Next, the private branch exchange 12 sends a calling signal to the sixth telephone set 10 and the seventh telephone set 11 (reporting telephone set), and executes a call for reporting the occurrence of an abnormality (S206). Therefore, when the sixth telephone set 10 makes an incoming call response first (S207), the private branch exchange 12 stops calling the seventh telephone set 11 in response to the incoming call response (S208). Subsequently, the private branch exchange 12 notifies the sixth telephone 10 of information (for example, sensor name) about the first sensor 2 by voice (S209). Further, the private branch exchange 12 performs a call to the first telephone 5 corresponding to the first sensor 2 (S210), and connects the sixth telephone 10 and the first telephone 5 to a state in which two-way communication is possible. (S211). Thereafter, voice listening, warning issuance, and the like are executed between the sixth telephone set 10 and the first telephone set 5 (S212). Although the case where the sixth telephone 10 responds to the incoming call first in S207 is shown, the same procedure can be executed when the seventh telephone 11 answers the incoming call first.

  FIG. 5 is a sequence diagram showing a second security monitoring procedure in the telephone system shown in FIG. Here, it is assumed that the second sensor 3 for detecting an abnormality has the correspondence shown in FIG. 2 for the monitoring telephone and the like, and the connection between the reporting telephone and the monitoring telephone is executed in the “dial input” connection mode. Is done. The detailed operations in the following procedures are the same as those described with reference to FIG. 1 or FIG.

  In the security monitoring procedure shown in FIG. 5, the procedure (S301 to S307) from when the second sensor 3 detects an abnormality to be monitored until the sixth telephone 10 responds to the incoming call (S301 to S307) is shown in S201 shown in FIG. To S207.

  When the sixth telephone set 10 responds to the incoming call first in S307, the private branch exchange 12 enters a state of waiting for a dial input operation of the user using the sixth telephone set 10 (that is, waiting for a push signal reception). Therefore, a dial input operation by the user is performed on the sixth telephone set 10 within a predetermined time (S308), and when the private branch exchange 12 receives an appropriate push signal (S309), the private branch exchange 12 receives the seventh telephone set. 11 is stopped (S310). Subsequently, the private branch exchange 12 notifies the sixth telephone 10 of information about the second sensor 3 (for example, the sensor name) by voice (S311). Further, the private branch exchange 12 executes a call to the second telephone 6 corresponding to the second sensor 3 (S312), and connects the sixth telephone 10 and the second telephone 6 to a state in which two-way communication is possible. (S313). Thereafter, voice listening, warning issuance, etc. are executed between the sixth telephone 10 and the second telephone 6 (S314).

  FIG. 6 is a sequence diagram showing a third security monitoring procedure in the telephone system shown in FIG. Here, the first telephone (monitoring telephone) 5 and the sixth telephone (reporting telephone) 10 are already connected so that two-way communication is possible by executing the security monitoring procedure as shown in FIG. Suppose that it is in the state (S400). Further, the third sensor 4 for detecting an abnormality has the correspondence relationship shown in FIG. 2 for the monitoring telephone and the like, and the connection between the notification telephone and the monitoring telephone is executed in the “automatic” connection mode. .

  In the security monitoring procedure shown in FIG. 6, in order to notify the sixth telephone set 10 and the seventh telephone set 11 (report telephone) of the occurrence of an abnormality after the third sensor 4 detects the abnormality to be monitored. The procedure (S401 to S405) until the call is executed is the same as S201 to S205 shown in FIG.

  Since the private branch exchange 12 knows that the sixth telephone 10, which is a telephone for notification corresponding to the third sensor 4, is already in a two-way call with the first telephone 5, the telephone for notification is not called. Then, the connection between the sixth telephone set 10 (reporting telephone set) and the first telephone set 5 (monitoring telephone set) is disconnected (S406). Then, the private branch exchange 12 notifies the sixth telephone 10 of information (for example, sensor name) about the third sensor 4 by voice (S407). Further, the private branch exchange 12 executes a call to the third telephone set 7 corresponding to the third sensor 4 (S408), and connects the sixth telephone set 10 and the third telephone set 7 in a state where two-way communication is possible. (S409). Thereafter, voice listening, alarm issuing, etc. are executed between the sixth telephone set 10 and the first telephone set 5 (S410).

  Although the present invention has been described in detail based on specific embodiments, these embodiments are merely examples, and the present invention is not limited to these embodiments. For example, a VoIP (Voice over Internet Protocol) function can be incorporated in a private branch exchange of the telephone system according to the present invention, and a security monitoring function similar to the above can be executed using a telephone connected to an IP network.

  According to the private branch exchange, the telephone system, and the security monitoring method according to the present invention, when an abnormality occurs in the monitoring target of the sensor, an abnormal situation is grasped or a warning is given to the abnormality from the report destination that has been notified of the abnormality occurrence. This is useful as a security monitoring method using a private branch exchange, a telephone system, and a telephone system having a security function that can be appropriately performed and that notifies a predetermined report destination when an abnormality occurs in a monitoring target.
