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

  A safety confirmation device 1 shown in FIG. 1 is a device that is installed in a living room or the like of a residence to confirm the safety of a resident such as an elderly living alone.

  As shown in FIG. 1 (A), the safety confirmation device 1 includes a substantially rectangular parallelepiped device exterior portion 10, and the device exterior portion 10 has human sensations on the front (front side), right side, and left side. A sensor 12 is provided. Further, a detection display unit 17 and a detection mode display unit 18 are provided on the front, a detection mode switching SW 14 is provided on the right side, and an emergency button 15 and a speaker unit 23 are fixed on the upper surface (upper side). It includes a placement unit 110 of the telephone 32, and includes a measurement time setting SW 16 (see FIG. 2) and a mode switching SW 13 (see FIG. 2) on the bottom surface.

As shown in FIG. 1B, the human sensor 12 as the detection means is accommodated in an accommodating portion 10 </ b> A provided in the apparatus exterior portion 10. The human sensor 12 includes, for example, a pyroelectric infrared sensor main body 12A and a lens 12B. The pyroelectric infrared sensor detects a human body based on the input of infrared rays as detection waves.
The optical axis AA of the lens 12B of the human sensor 12 provided on the front surface of the apparatus exterior portion 10 is perpendicular to the front surface of the apparatus exterior portion 10 and parallel to the bottom surface. In addition, a mask member 121 is provided at the outlet of the accommodating portion 10A as a shielding unit that shields the substantially lower half of the human sensor 12. The viewing angle characteristic of the human sensor 12 is limited to only the upper side from the horizontal, for example, by the mask member 121, and the viewing angle after the limitation is α. In addition, the position of the mask member 121 can be adjusted in the vertical direction by the position adjustment mechanism 122 configured by the long hole 121A having a long axis along the vertical direction and the fixing screw 122A. The characteristics can be adjusted. Accordingly, the human sensor 12 can be configured not to detect a position lower than a predetermined height. Here, the “predetermined height” may be a height that can prevent erroneous detection of a small animal or the like. The human sensor 12 provided on the right side surface and the left side surface of the apparatus exterior portion 10 has the same configuration.

  Next, as shown in FIG. 2, the safety confirmation device 1 includes a RAM 111 and a ROM 112, and includes a control unit 11 that performs overall control of the device, a human sensor 12, a mode switching SW 13, and a detection Mode switch 14, emergency button 15, measurement time setting SW 16, detection display unit 17, detection mode display unit 18, line IF unit 19, auto dialer 20, audio output unit 21, and ringer signal generation Unit 22, speaker unit 23, power supply unit 24, and EPROM 27. Those functional components are connected via a bus 28.

  The mode switching SW 13 is a switch for switching the operation of the safety confirmation device 1 to one of a detection mode, a telephone number registration mode, and a telephone number reading mode.

  The detection mode switching SW 14 is either a safety confirmation mode for confirming the safety of the resident or an answering mode for detecting an intruder into the room L of the answering house when the resident goes out. This is a switch for switching to the mode. The detection mode switching SW 14 functions as a switching unit that receives a switching instruction to the answering machine mode.

  The emergency button 15 is a button for shifting the safety confirmation device 1 to an emergency mode for reporting an emergency. The emergency button 15 functions as an input unit that receives an input instruction.

  The measurement time setting SW 16 is a switch for setting a predetermined measurement time of the human sensor 12 in the safety confirmation mode. The predetermined measurement time is selected from, for example, 6, 8, 12, 16, 24, and 48 hours.

  The detection display part 17 is comprised by LED, for example. The detection display unit 17 is lit red when detected by the human sensor 12. In addition, it flashes red when a call is made to a fixed telephone, which will be described later, and when a report is sent to a report destination.

  The detection mode display part 18 is comprised by LED, for example. The detection mode display unit 18 lights up in green in the safety confirmation mode, and lights up red or flashes red in the answering machine mode.

The line IF unit 19 as a determination means detects a signal between the fixed telephone 32 and the telephone line (general public line) 31, and determines whether or not the handset of the fixed telephone 32 is raised and is in an off-hook state. .
Specifically, the line IF unit 19 detects a state where the handset is returned to the handset base and the line is disconnected as an on-hook state. Further, when the line is connected and the telephone is in a state such as during a call or during dialing, an off-hook state is detected.
The line IF unit 19 connects and disconnects the fixed telephone 32 and the telephone line (general public line) 31 under the control of the control unit 11.

  The auto dialer 20 creates a PB signal by combining a DTMF (Dual-Tone Multi-Frequency) sound corresponding to the registered report destination telephone number when reporting to the report destination telephone in the safety confirmation mode, answering machine mode, and emergency mode. It is sent to a telephone line (general public line) 31.

  The voice output unit 21 outputs a voice signal for reporting to the reporting destination telephone in the safety confirmation mode, the answering machine mode, and the emergency mode. In addition, a voice signal for notification by the fixed telephone 32 in the answering machine mode is output.

  A ringer signal generation unit 22 as a calling unit generates a ringer signal for calling the fixed telephone 32.

  The speaker unit 23 converts the PB signal corresponding to the registered report destination into sound waves during the reporting process to the registered report destination.

  The power supply unit 24 receives power from a power supply line supplied to a telephone line (general public line) 31. A DC voltage of 48 V is supplied to terminals T1 and T2 (see FIG. 3) of a telephone line (general public line) 31 from a voltage source of a central office exchange. Using this DC voltage as a power supply line, the power supply unit 24 receives power. This DC voltage is supplied independently from the commercial AC power supply, and is also supplied when the commercial AC power supply fails.

  EPROM 27 as a storage means is a non-volatile memory, and stores the telephone number of the report destination.

  The control unit 11 reads out the processing program stored in the ROM 112 and develops it in the work area of the RAM 111, and executes various processes described later in cooperation with the processing program.

The control unit 11 functions as a reporting unit that reports to the telephone having the reporting destination telephone number stored in the EPROM 27 serving as a storage unit via the telephone line by the auto dialer 20 and the voice output unit 21.
The control unit 11 causes the line IF unit 19 to determine whether the fixed telephone 32 is in an off-hook state when the human sensor 12 does not detect a human body for a predetermined measurement time. When in the off-hook state, it functions as a control unit that causes the reporting unit to report.
When the fixed telephone 32 is not in the off-hook state, the control unit 11 as a control means causes the ringer signal generator 22 to call the fixed telephone 32 for the first calling time, and the first calling time. When the human sensor 12 does not detect the human body during the period, the notification means is notified.

  The control unit 11 as the control unit causes the reporting unit to report when an input instruction is given by the emergency button 15.

  In addition, the control unit 11 as a control unit causes the human sensor 12 to start detecting a human body after a predetermined waiting time (for example, 5 minutes) has elapsed from when the switching to the answering machine mode is instructed by the detection mode switching SW 14. When the human body is detected after the start, the fixed-line telephone 32 is caused to make a call during the second ringing time by the ringer signal generator 22, and when the second ringing time elapses, the reporting means is notified. Make it.

  Next, the installation of the safety confirmation device 1 will be described with reference to FIG. The safety confirmation device 1 is, for example, in a room L of a house J so that the bottom surface of the device 1 is substantially parallel to the floor surface F of the room L, and the height of the human sensor 12 from the floor surface F. Is set on a stand S or the like so that a predetermined height h is obtained. The predetermined height h is, for example, the waist height when the resident H1 stands. The safety confirmation device 1 is connected to a telephone line (general public line) 31 and a fixed telephone 32 via a telephone line connection terminal unit 25 and a telephone connection terminal unit 26 provided on the back of the safety confirmation device 1, respectively.

  As described with reference to FIG. 1B, the human sensor 12 has the viewing angle characteristics of the human sensor 12 limited to, for example, only from the horizontal to the upper side by the mask member 121, and the viewing angle after the limitation is Since it is α, the detection range in the vertical direction is limited to the upper area A from the predetermined height (h), and the lower area B is not detected. That is, a mask member 121 is provided as a shielding unit that shields an input of a detection wave from a position lower than the human sensor 12. Further, the ranges of the areas A and B can be adjusted by the position adjusting mechanism 122 described above.

  The safety confirmation device 1 determines that it is abnormal when a human body is not detected by the human sensor 12 for a predetermined measurement time. However, even if there is no human body detection, the safety confirmation device 1 lives in the region B. If a small animal such as the cat C is detected, it cannot be determined that there is an abnormality. The safety confirmation device 1 is configured so that the standing resident H1 can be detected in the region A, while the small animals in the region B and the falling resident are not detected, and the accuracy of confirmation of the resident's safety is improved. Can do.

  Further, since the human sensor 12 is provided on the front surface, right side surface, and left side surface of the device exterior portion 10, the safety confirmation device can be provided by directing the back surface (rear side) of the device exterior portion 10 toward the wall side of the room L. One human sensor 12 can detect almost all directions in the horizontal direction such as a living room.

Next, operation | movement of the safety confirmation apparatus 1 which concerns on this embodiment is demonstrated. First, the safety confirmation mode process will be described with reference to FIG.
First, when the detection mode switching SW 14 is switched to the safety confirmation mode, the control unit 11 sets the detection mode to the safety confirmation mode (step S1). Then, the detection mode display unit 18 is lit in green (step S2).

  Next, the control part 11 resets the timer which times measurement time (step S3). Next, the control unit 11 determines whether or not the emergency button 15 is pressed (step S4). When the control unit 11 determines that the emergency button 15 is pressed (step S4; YES), the control unit 11 shifts to the emergency mode (step S4). S5) When it is determined that the emergency button 15 is not pressed (step S4; NO), the process proceeds to step S6.

  Next, the control unit 11 determines whether or not the detection mode switching SW 14 is in the safety confirmation mode (step S6). When the control unit 11 determines that the detection mode switching SW 14 is not in the safety confirmation mode (step S6; NO), the control unit 11 proceeds to the answering machine mode process ( If it is determined that the safety confirmation mode is set (step S7) (step S6; YES), the process proceeds to step S8.

  Next, the control unit 11 determines whether or not the human sensor 12 has detected a human body (step S8). When the human sensor 12 determines that a human body has been detected (step S8; YES), the process returns to step S3. On the other hand, when the human sensor 12 determines that the human body is not detected (step S8; NO), the process proceeds to step S9, where it is determined whether the current time is within the set measurement time, and the current measurement time is set. If it is determined that it is within (step S9; YES), the process returns to step S4. On the other hand, if it is determined that the current time is not within the set measurement time (step S9; NO), the process proceeds to step S10.

  Next, the control unit 11 determines whether or not the handset of the fixed telephone 32 is lifted and is in an off-hook state (step S10). If it is determined that the handset of the fixed telephone 32 is raised and is in an off-hook state (step S10; YES), the process proceeds to step S16. On the other hand, if it is determined that the fixed telephone 32 is not in the off-hook state (step S10; NO), the process proceeds to step S11. The branch in step S10 is provided for the following reason. If the handset of the fixed telephone 32 is raised and is in an off-hook state, the fixed telephone 32 cannot be called. Therefore, the subsequent processing differs depending on whether or not the fixed telephone 32 is in an off-hook state.

  In step S11, the control part 11 calls the fixed telephone 32 connected to the safety confirmation apparatus 1 by the ringer signal generation part 22 as a calling means (step S11).

  Next, the control unit 11 determines whether or not the human sensor 12 has detected a human body (step S12). When it is determined that the human sensor 12 has detected a human body (step S12; YES), the call is terminated (step S13), and the process proceeds to step S3. If it is determined that the human sensor 12 has not detected a human body (step S12; NO), it is determined whether or not a first calling time (for example, 60 seconds) has elapsed since the start of calling (step S14). If it is determined that the first calling time (for example, 60 seconds) has not elapsed since the start of calling (step S14; NO), the process returns to step S12. If it is determined that the first calling time (for example, 60 seconds) has elapsed since the start of calling (step S14; YES), the process proceeds to step S15.

  Next, the control unit 11 ends the call to the fixed telephone 32 (step S15), and performs a notification process to the registration notification destination (step S16). Then, the process proceeds to step S12.

  Next, the notification process to the registered report destination will be described with reference to FIG.

  First, the control part 11 operates the speaker part 23 (step S21). Next, the control unit 11 sets the following parameters to initial values (step S22). Parameters are: n: number of report destinations, i: order of report destinations, j (i): report end flag (j (i) = 0: not finished, j (i) = 1: finished), k: retry count memory , And these values are initialized as n = 4, i = 0, j (i) = 0 (for all i), and k = 0.

  Next, the control unit 11 increases the value of i by 1 and sets i = 1 (step S23).

  Next, the control unit 11 determines whether or not the value of j (i) is 0 (step S24). If it is determined that j (i) = 0 (step S24; YES), the call destination related to the i-th telephone number is called by the auto dialer 20 (step S25). On the other hand, if it is determined that j (i) = 0 is not satisfied (step S24; NO), the process proceeds to step S31.

  Next, the control unit 11 determines whether or not the reporting destination telephone is connected (step S26). If it is determined that the telephone device to be notified has been connected (step S26; YES), the audio output unit 21 reports the contents corresponding to the safety confirmation mode / emergency mode / answering machine mode with an audio signal (step S27). In the safety confirmation mode, for example, a voice signal is used to notify the content that “the body sensor has not been detected for a certain period of time. Please confirm.” In the case of an answering machine, it is handled as if the telephone device of the report destination is connected.

  Next, the control unit 11 sets j (1) = 1 in step S28. That is, the report end flag of the first (i = 1) report destination is set to end.

  On the other hand, if the control unit 11 determines in step S26 that the destination telephone is not connected (step S26; NO), the control unit 11 determines whether or not a predetermined time (1 minute) has elapsed (step S29). If it is determined that the time (1 minute) has not elapsed (step S29; NO), the process returns to step S26, and if it is determined that the predetermined time (1 minute) has elapsed (step S29; YES), j (1) in step S30. Set to = 0.

  Next, the control unit 11 determines whether i <n is satisfied (step S31). If it is determined that i <n (step S31; YES), the process returns to step S23, the value of i is incremented by 1 (i = 2), and the second destination is notified of steps S23 to S30. Processes are executed sequentially. The processes in steps S23 to S30 are repeated until it is determined in step S31 that i <n is not satisfied.

  Next, if the control part 11 judges that it is not i <n in step S31 (step S31; NO), it will transfer to step S32.

  In step S32, the control unit 11 determines whether there is i having j (i) = 0, that is, whether there is an unreported destination, and if there is i having j (i) = 0. If it is determined (step S32; YES), the value of k is increased by 1 and i = 0 is set (step S33), and whether or not k <4 (that is, whether or not the number of retries is less than 5). Is determined (step S34).

  Next, when the control unit 11 determines that k <4, that is, the number of retries is less than 5 (step S34; YES), the control unit 11 returns to step S23 and k = 4 (5 retries). Until it becomes, the process of step S23-step S33 is performed.

  Next, if the control part 11 judges that it is not k <4 in step S34 (step S34; NO), it will transfer to step S35.

  If it is determined in step S32 that there is no i having j (i) = 0 (step S32; NO), the process proceeds to step S35.

  In step S35, the control unit 11 stops the operation of the speaker unit 23 and ends the notification process.

  Next, the emergency mode process will be described. The emergency mode process is started when it is determined that the emergency button is pressed in step S4 of FIG.

  If it is determined that the emergency button has been pressed in step S4 of FIG. 4, the control unit 11 performs a notification process to the registered notification destination.

  Since the reporting process to the registered reporting destination is as described with reference to FIG. 5, only the differences will be described. Even in the emergency mode, the speaker unit 23 is activated in step S21 of FIG. Since the speaker unit 23 is activated, the PB signal corresponding to the report destination is output as a sound wave from the speaker unit 23, and the resident who pressed the emergency button 15 can hear the PB signal and be notified. Recognize that

  Further, in the emergency mode, in step S28 of FIG. 5, the content “An emergency call has been received from the caller. Please respond promptly” is notified by voice signal.

  Next, the answering machine mode process will be described with reference to FIG. The answering machine mode process is a process performed when the detection mode switching SW 14 is switched to the answering machine mode as described with reference to FIG.

  First, the control unit 11 displays an answering machine mode notice (step S51). Specifically, the detection mode display unit 18 blinks red.

  Next, in step S52, the control unit 11 determines whether or not there is an instruction to switch to the safety confirmation mode by the detection mode switching SW14, and determines that there is an instruction to switch to the safety confirmation mode (step S52; YES). ) When this process is terminated and it is determined that there is no instruction to switch to the safety confirmation mode (step S52; NO), the process proceeds to step S53, and the answering machine mode process is started and a predetermined waiting time (for example, 5 minutes) has elapsed. It is determined whether or not it has been done (step S53). When it is determined that a predetermined waiting time (for example, 5 minutes) has elapsed (step S53; YES), the process proceeds to step S64, and when it is determined that a predetermined waiting time (for example, 5 minutes) has not elapsed (step S53; NO). Control goes to step S52.

  Next, the control part 11 starts the detection in answering machine mode (step S54). That is, detection by the human sensor 12 is started. At the same time, the detection mode display unit 18 is changed from red flashing to red lighting.

  Next, the control unit 11 determines whether or not the human sensor 12 has detected a human body (step S55), and determines that the human sensor 12 has not detected a human body (step S55; NO), returns to step S55. If the detection is continued and it is determined that the human sensor 12 has detected the human body (step S55; YES), the detection mode display unit 18 is changed from red blinking to red lighting (step S56), and the fixed telephone 32 is called (step S56). Step S57).

  Here, the steps from the step of calling the fixed telephone 32 (step S57) to the step S63 are steps for ending the answering machine mode when the resident returns home.

  Next, the control unit 11 determines whether or not there is an instruction to switch to the safety confirmation mode (step S58), and determines that there is an instruction to switch to the safety confirmation mode (step S58; YES), this process is performed. finish.

  On the other hand, if the control unit 11 determines in step S58 that there is no instruction to switch to the safety confirmation mode (step S58; NO), whether the handset of the fixed telephone 32 has been raised (is in an off-hook state) or not. If it is determined (step S59) and it is determined that the handset of the fixed telephone 32 has been raised (step S59; YES), the call to the fixed telephone 32 is terminated (step S60), and “switch from answering machine setting to normal setting. Is notified three times (step S61), it is determined whether there is an instruction to switch to the safety confirmation mode (step S62), and if it is determined that there is an instruction to switch to the safety confirmation mode (step S62). YES), this process is terminated.

  If it is determined in step S62 that there is no instruction to switch to the safety confirmation mode (step S62; NO), whether or not a predetermined elapsed time (for example, 2 minutes) has elapsed after the notification in step S61. If it judges (step S63) and it judges that predetermined | prescribed elapsed time has not passed after alert | reporting of step S61 (step S63; NO), it will return to step S62.

  On the other hand, when the control unit 11 determines in step S59 that the handset of the fixed telephone 32 is not raised (step S59; YES), after the call to the fixed telephone 32 (step S57), the second calling time (for example, It is determined whether or not five minutes have elapsed (step S64), and if it is determined that the second call time has not elapsed (step S64; NO), the process returns to step S57 and if it is determined that the second call time has elapsed. (Step S64; YES), the call is terminated (Step S65).

  Next, when it is determined in step S63 that a predetermined elapsed time (for example, 2 minutes) has elapsed after notification in step S61 (step S63; YES), or when step S65 is executed, the control unit 11 registers. A reporting process to the reporting destination is performed (step S66).

  The reporting process to the registered reporting destination is the same as the process shown in FIG. 5 except that the reporting content is different. In the answering machine mode, for example, the content “There was a response to the human sensor in the answering machine. Please check.” Is reported by an audio signal.

[Modification 1]
With reference to FIG. 7, the human sensor installation structure based on the modification 1 is demonstrated. In the first modification, the human sensor 12 is tilted and held upward by an angle α from the vertical direction with respect to the apparatus exterior portion 10 (front surface 10), and thus has a viewing angle 2α from the horizontal to the upper direction. Therefore, the human sensor 12 is configured not to detect a position lower than the human sensor 12. With such an installation structure, similarly to the embodiment, the region B described in FIG. 3 can be outside the detection range.

With reference to FIG. 9, the human sensor installation structure based on the modification 3 is demonstrated. The human sensor installation structure of Modification 3 is similar to the installation structure of the embodiment shown in FIG. 1B, in which the lens 12B is housed in the housing portion 10B, but the lower side of the lens 12B as a shielding means. The member that covers the half is not a mask member that is independent of the apparatus exterior portion 10, but is integrally formed with the member of the apparatus exterior portion 10. By configuring the human sensor installation structure on the apparatus exterior portion 10 in this manner, the region B described with reference to FIG. 3 can be out of the detection range as in the embodiment.

As described above, the safety confirmation device 1 according to the present embodiment is the safety confirmation device 1 connected to the telephone line (general public line) 31 and the fixed telephone 32, and includes the human sensor 12 that detects the human body. , The ringer signal generator 22 for calling the fixed telephone 32, the EPROM 27 for storing the telephone number to be notified, and the line IF for identifying whether or not the fixed telephone 32 is in an off-hook state by raising the handset of the fixed telephone 32 Unit 19, and a control unit 11, an auto dialer 20 and a voice output unit 21, which serve as notification means for making a report via a telephone line (general public line) 31 to a telephone having a report destination telephone number stored in EPROM 27, The control unit 11 as a control means is fixed by the line IF unit 19 when the human sensor 12 does not detect a human body for a predetermined measurement time. It is determined whether or not the telephone is in an off-hook state, and when the fixed telephone 32 is in an off-hook state, the notification means is notified and the control unit 11 indicates that the fixed telephone 32 is in an off-hook state.

Accordingly, the human sensor 12 is configured not to detect a small animal or the like, and can improve the accuracy of confirmation of the safety of the resident by the safety confirmation device 1.

The shielding means 123 includes a cover member that covers the surface of the substantially lower half circumference of the human sensor 12.
As a result, the human sensor 12 is restricted from being detected at a position lower than the human sensor 12, so the human sensor 12 is configured not to detect a small animal or the like. The accuracy of confirmation of safety can be improved.
The shielding unit 121 includes a position adjustment mechanism 122 that adjusts the position of the shielding unit in the vertical direction.
Thereby, the position of the up-down direction which shields the input of a detection wave can be adjusted by adjusting the position of a shielding means, and the accuracy of the confirmation of the resident's safety by the safety confirmation apparatus 1 can be improved.

The safety confirmation device 1 includes a plurality of human sensors 12. For example, the human sensor 12 is provided on the front surface, right side surface, and left side surface of the apparatus exterior portion 10.
Thereby, for example, the safety confirmation device 1 detects the almost all directions in the horizontal direction such as the living room by turning the back surface (rear side) of the device exterior part 10 toward the wall side of the room L. The accuracy of the confirmation of the safety of the resident by 1 can be improved.

In addition, the safety confirmation device 1 includes an emergency button 15 that receives an input instruction, and the control unit 11 causes the notification unit to make a notification when an input instruction is issued by the emergency button 15.
Thereby, in addition to the safety confirmation mode process, an emergency notification function is obtained, so that the accuracy of confirmation of the safety of the resident by the safety confirmation device 1 can be improved.

In addition, the safety confirmation device 1 includes a detection mode switching SW 14 as a switching unit that receives a switching instruction to the answering machine mode. When the human sensor 12 starts detecting the human body after the waiting time has elapsed and the human body is detected after the start of the waiting time, the ringer signal generator 22 serving as a calling unit for the fixed telephone 32 performs the second call time. When a second call time elapses, the notification means is notified when the call is made.
Thereby, in addition to the safety confirmation mode process, the notification function by the answering machine mode process is obtained, so that the accuracy of confirmation of the safety of the resident by the safety confirmation device 1 can be improved.

  The safety confirmation device 1 is driven by receiving power from a power line supplied to a telephone line (general public line). As a result, the power supply line supplied to the telephone line can be utilized.

In the safety confirmation device 1, the human sensor 12 includes a pyroelectric infrared sensor.
Thereby, human body detection can be performed efficiently.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. In the present embodiment, the pyroelectric infrared sensor is used as the human sensor 12, but an infrared sensor other than the pyroelectric sensor may be used, and a detection wave is emitted from the human sensor such as an ultrasonic sensor. A sensor that detects a human body based on a change in the reflected wave may be used. In addition, the human sensor may be configured so as to be separated from the apparatus exterior and can be placed separately.

  In the present embodiment, the safety confirmation device 1 is driven by receiving power from the power line supplied to the telephone line. However, the safety confirmation device receives power from the power line supplied to the telephone line. In addition to driving 1, another power source may be used.
