FIG. 8 is a flowchart of the threatening process.

  First, the user performs an operation (security group setting operation) for selecting a plurality of telephones to be set in the security mode from among the N button telephones 2-1 to 2-N (procedure P1). This operation can be performed with any key telephone, but here it is assumed to be performed with the key telephone 2-1. The user uses the operation unit 26 of the key telephone 2-1 to input the extension number of the key telephone desired to set the crime prevention mode. The extension number is detected by the control unit 21 of the key telephone 2-1, and the detection signal is transmitted to the main apparatus 1 via the extension interface unit 22 and the extension transmission path 6, and the extension interface unit 13 controls the control unit 11. And stored in the storage unit 16. Since the key telephone set as a security group needs to detect an intruder, it must include at least one button telephone with an anomaly detection sensor. It is preferable to form one security group with telephones arranged nearby. Moreover, you may set a some group within the range which can lay a cable from the main apparatus 1 instead of one crime prevention group. Here, the sensor-equipped key telephone 2-1 and the sensorless key telephone 2-2 are grouped.

  Next, the user registers the shooting area identification information of the camera 5 in the storage unit 16 of the main apparatus 1 so that the camera 5 can shoot the place where the key telephone set set as the security group is arranged (procedure P2). ). In this registration operation, the PC 3 is operated to perform communication via the communication network 7 between the PC 3 and the camera 5, and the installation location of the sensor-equipped key telephone 2-1 in which the shooting area of the camera 5 is set as the crime prevention group. Set to include. The imaging region identification information set in this way is stored in the storage unit 32 of the PC 3, transmitted to the main apparatus 1 via the communication network 7, and stored in the storage unit 16.

  Next, the user performs a crime prevention mode setting operation by pressing a predetermined function key disposed on the operation unit 26 of the key telephone 2 (procedure P3). This operation can be performed using any of the key telephones 2-1 to 2-N, but here the telephone 2-2 is used. The security mode setting operation is detected by the control unit 21 of the key telephone 2-2, and the detection signal is transmitted to the main apparatus 1 via the extension interface unit 22 and the extension transmission path 6 and controlled from the extension interface unit 13. Is transmitted to the unit 11. In the following description, the description of the data flow in the main device 1 and the key telephone 2 and the description that the communication between the main device 1 and the key telephone 2 is performed via the extension transmission line 6 will be described. Omitted.

The control unit 11 of the main apparatus 1 executes the process shown in FIG. First, the presence / absence of a detection signal for the crime prevention mode setting operation is determined (step S1). If there is, a determination is made as to whether any of the key telephones in the security group set in step P1 is in use (step S1). S2). If EKT in use there is no, the timer is started (step S3), and setting the security mode when a predetermined time t ₁ has elapsed (time-up) (step S4, S5). The fact that the crime prevention mode has been set is notified to the group-set key telephones 2-1 and 2-2 (procedure P4). When the key telephones 2-1 and 2-2 are notified that the crime prevention mode has been set, they are displayed on the LCD display unit 24 and a part of the LED light source 25, for example, the function key Lights up.

When the crime prevention mode is set, when the abnormality detection sensor 28 of the key telephone 2-1 with the abnormality detection sensor generates a detection signal, this is notified to the main device 1, and a threatening action (alarm sound output, etc.) to be described later ). Here, the reason for setting the crime prevention mode after the elapse of the predetermined time t ₁ from the crime prevention mode setting operation is that when the crime prevention mode is set immediately after the crime prevention mode setting operation, the user who executed the setting operation is detected by the abnormality detection sensor 28, This is because threatening actions are executed. In order to prevent this setting operation from being set to the crime prevention mode when a predetermined function key is accidentally pressed, a confirmation screen is displayed on the LCD display unit 24 by pressing the predetermined function key, and the confirmation key is pressed. It is suitable to make it perform.

  If it is determined in step S2 that there is a key phone in use, the security mode cannot be set because there is a key phone in use for the key phone 2-2 that has executed the security mode setting operation. Display is performed (step S6).

  When the crime prevention mode is set as described above, the control unit 11 of the main device 1 executes the process shown in FIG. First, the presence / absence of a sensor state notification transmitted from the key telephone with sensor 2-1 is determined (step S11). When there is a sensor state notification, it is determined whether or not it is a sensor ON notification, that is, a notification that the abnormality detection sensor 28 is generating a detection signal (step S12). As shown in procedure P5 of FIG. 5, the abnormality detection sensor 28 of the key telephone 2-1 with the abnormality detection sensor generates a detection signal (sensor ON signal) and notifies the main apparatus 1 from the key telephone 2-1. Then, the determination in step S12 is “Yes”, and log recording, camera control, and timer start are executed (step S13).

  Here, log recording refers to the date and time when the abnormality detection sensor 28 generated the sensor ON signal (date and time when the main device 1 received the sensor ON notification) and the identification number (extension number) of the key telephone 2-1 as the main device. 1 storage unit 16 and the server 4. The information recorded in the log may be displayed on the LCD display unit 24 of the key telephone in the security group.

  The camera control is to control the shooting area of the camera 5 so as to include the installation location of the key telephone 2-1, and to start the operation of saving the shot image data in the server 4 (procedure P6). The camera 5 stores the captured image data in the image data storage area of the storage unit 45, and performs an operation of overwriting new image data on the old image data when the storage capacity of the storage area becomes zero. . In this camera control, the main device 1 transmits the shooting area identification information stored in the storage unit 16 to the camera 5 via the communication network 7, and the camera 5 controls the pan / tilt control unit 47 according to the received shooting area identification information. The camera signal processing unit 43 generates image data to be compressed and transmits the image data to the server 4 via the communication network 7. Thereby, the area where the intruder exists is photographed, and the image data is stored in the server 4 together with the log.

After the timer is started at step S13, until the predetermined time t ₂ has elapsed (time up), determines whether or not an operation for canceling the security mode from the key telephone set in the security group is made (step S14, S15) . Then, if there is an operation to cancel the security mode before the predetermined time t ₂ elapses, the security mode is canceled (step S17), and if not, a threatening process (FIG. 8) described later is started (step S16). If it is determined in step S12 that it is not a sensor ON notification (a sensor OFF notification indicating that the detection signal of the abnormality detection sensor 28 of the key telephone 2-1 with the abnormality detection sensor has disappeared), Ignored (step S18). By providing a timer that times up at the predetermined time t ₂ in this way, when the key telephone device is set in the security mode, the user who operates the key telephones in the group to cancel the security mode is provided. , Do not perform intimidating behavior.

Next, threatening processing will be described with reference to FIG.
First, the main device 1 generates a volume control signal for setting the audio output level of the audio processing unit 23 of the key telephones 2-1 and 2-2 in the group to a predetermined level (for example, the maximum level), and each button Transmit to the telephone (step S21, procedure P7). The key telephones 2-1 and 2-2 receive the volume control signal, and the control unit 21 sets the output volume level of the voice processing unit 23.

  Next, in the main apparatus 1, generation of a control signal for outputting a ringing sound (alarm sound) from the voice processing units 23 of the key telephones 2-1 and 2-2 (step S22), and key telephones 2-1 and 2 -2 generates a light emission control signal (step S23) for outputting threatening light emission (alarm light) from all the LEDs constituting the LED light source 25, and sends these control signals to the key telephones 2-1 and 2-2. (Procedures P8 and P9). The key telephones 2-1 and 2-2 receive these control signals, output a ringing sound from the sound output unit 23, and output warning light from all the LEDs constituting the LED light source 25. At this time, an alarm sound and an alarm light may be output from a key telephone outside the crime prevention group.

  Next, in the main device 1, a process (step S24) for outputting a threatening sound (alarm sound) from an external speaker (private broadcasting, etc.) (not shown) and a place where the user who has performed the setting operation of the crime prevention mode Automatic transmission is made to a home or the like (step S25). The destination telephone that has automatically made a call inputs a peripheral voice from the handset of the voice processing unit 23 of the key telephones 2-1 and 2-2 by transmitting a predetermined signal in response to the automatic call, By transferring to the automatic destination, the sound around the key telephones 2-1 and 2-2 may be monitored from the outside.

Further outputs starts a timer for measuring the time t ₃ when stopping the ringing sound (warning sound) (step S26), when the time is up (Step S27 Yes) at the EKT 2-1 and 2-2 A control signal for stopping the ringing sound (alarm sound) being output from the voice output unit 23 is generated (step S28) and transmitted to the key telephones 2-1 and 2-2 (procedure P10). The key telephones 2-1 and 2-2 receive this control signal and stop outputting the ringing sound from the voice output unit 23. At this time, the output of the threatening sound from the external speaker may be stopped. Next, the main device 1 generates a volume control signal for setting the audio output level of the audio processing unit 23 of the key telephones 2-1 and 2-2 to the volume level before the threatening operation, and transmits it to the respective key telephones. (Procedure P11). The key telephones 2-1 and 2-2 receive this control signal, and return the audio output level of the audio output unit 23 to the volume level before the threatening operation. Thereafter, even if the intruder leaves the sensing range of the abnormality detection sensor 28 of the key telephone 2-1, and the sensor OFF is notified (procedure P12), the main device 1 ignores it and performs the threatening process by the LED light emitting unit 25. continue. Here, a case has been exemplified where the sensor OFF is notified after the time t _3, since the main device 1 even when the sensor OFF is notified before the time passes t ₃ ignore it until time passes t ₃ performs threatening treatment with ringing sound (warning sound) and alarm light, after a lapse of time t ₃ stops outputting the ringing sound (warning sound), the output of the alarm light will continue .

Then, the user uses a key telephone set 2-1 for performing security mode releasing operation, close to the key telephone set 2-1, the abnormality detection sensor 28 is crime prevention mode after generating a sensor ON signal within the time t ₂ When the release operation is performed (procedures P13, P14, steps S14, S17), the main device 1 performs light emission control for stopping the threatening light emission in the LED light sources 25 of the key telephones 2-1 and 2-2 in the security group. A signal is generated and transmitted to the key telephones 2-1 and 2-2 (procedure P15). The key telephones 2-1 and 2-2 receive this control signal and stop the intimidating light emission in the LED light source 25.

  In the above embodiment, only one button telephone with an abnormality detection sensor exists in one security group, but a plurality of key telephones with an abnormality detection sensor exist in one security group. Good. In this case, in step P2 of FIG. 5, one camera is set so that it can shoot by switching the installation locations of a plurality of button telephones with abnormality detection sensors.
