It has been.

  The detection device 4 and the alarm device 6 can perform two-way wireless communication (at least wireless communication from the detection device 4 to the alarm device 6) by transmitting and receiving radio waves using the antennas 13 and 35. In addition, when the transmission / reception of a radio wave cannot be performed directly because the distance between the detection device 4 and the alarm device 6 is long, a relay device can be installed between the two. Further, by installing a PLC (Power Line Communication) modem in both the detection device 4 and the alarm device 6, PLC communication may be used instead of wireless communication.

  FIG. 6 is a block diagram showing a configuration of the detection device 4 shown in FIG. As shown in the connection relationship of FIG. 6, the detection device 4 includes a connection unit 12, a power supply unit 40, a moving object detection unit 41, a communication unit 42, a processing unit 43, a storage unit 44, a lighting unit 11, and an audio output unit 15. It is prepared for.

  The connection unit 12 is supplied with power from the socket 17 by being connected to the socket 17 shown in FIG. 2. As indicated by a broken line in FIG. 6, the power supply unit 40 uses the moving body detection unit 41, the communication unit 42, the processing unit 43, the storage unit 44, the illumination unit 11, and the sound that the connection unit 12 receives from the socket 17. This is supplied to the output unit 15. These processing units are driven by electric power supplied from the power supply unit 40.

  The moving body detection unit 41 is connected to the antenna 14 shown in FIG. 2 and includes, for example, a Doppler sensor using radio waves in the microwave region. The Doppler sensor transmits radio waves of a predetermined frequency from the transmitter toward the monitoring area, and receives reflected waves by the receiver. If there is a moving object in the monitoring area, the frequency of the reflected wave shifts due to the Doppler effect, so whether the moving object exists in the monitoring area by comparing the frequency of the transmitted radio wave with the frequency of the received radio wave. Whether or not can be detected.

  FIG. 7 is a block diagram illustrating an example of the configuration of the moving object detection unit 41. As shown in the connection relationship of FIG. 7, the moving object detection unit 41 includes a Doppler sensor 411, a low-pass filter (LPF) 412, comparison units 413 and 414, and a determination unit 415. The signal S1 output from the Doppler sensor 411 is input to the comparison unit 413 and the LPF 412. The LPF 412 outputs a signal S2 by attenuating a frequency component of, for example, 10 Hz or more in the signal S1. Thereby, even if water discharge is performed from the shower etc. in the bathroom 3, the signal S2 from which the high frequency component resulting from the water discharge was removed is obtained.

  The comparison unit 413 compares the value of the signal S1 with the first threshold value, and outputs the comparison result as a signal S3. The first threshold value is set to an appropriate value capable of distinguishing the movement of the hot water surface in the bathroom 3 from the human movement. The comparison unit 414 compares the value of the signal S2 with the second threshold value, and outputs the comparison result as the signal S4. The second threshold is set to an appropriate value that can distinguish the presence or absence of human movement. As described above, in the signal S2, high-frequency components resulting from water discharge from a shower or the like are removed, and therefore the presence or absence of human movement can be detected even when a shower or the like is used.

  The determination unit 415 determines the presence or absence of the movement of the monitored person in the bathroom 3 based on the signals S3 and S4. That is, when the value of the signal S1 is equal to or greater than the first threshold and the value of the signal S2 is equal to or greater than the second threshold, there is a movement of the monitored person in the bathroom 3 (that is, there is a moving object detection). If the value of the signal S1 is less than the first threshold value or the value of the signal S2 is less than the second threshold value, there is no movement of the monitored person in the bathroom 3 (that is, no moving object is detected). Is determined. And the result of the determination is output as signal S5.

  The communication unit 42 is connected to the antenna 13 illustrated in FIG. 2 and performs wireless communication with the alarm device 6. The processing unit 43 is, for example, a CPU. The storage unit 44 is, for example, a semiconductor memory, and stores a program 45 for operating the processing unit 43. The illumination part 11 is LED illumination, for example, and illuminates the bathroom 3 which is a monitoring area. The audio output unit 15 is a speaker, for example.

  FIG. 8 is a block diagram illustrating functions executed by the processing unit 43 by executing the program 45. By reading and executing the program 45 from the storage unit 44, the processing unit 43 functions as the determination unit 50, the activation control unit 51, the determination processing control unit 52, the time measuring unit 53, the sound control unit 54, and the illumination control unit 55. To do. In other words, the program 45 causes the computer mounted on the detection device 4 to function as the determination unit 50, the activation control unit 51, the determination processing control unit 52, the time measuring unit 53, the sound control unit 54, and the illumination control unit 55. It is a program for.

  The determination unit 50 performs a determination process (hereinafter referred to as “abnormality determination process”) as to whether or not an abnormality has occurred in the monitored person in the bathroom 3 based on the detection result by the moving object detection unit 41. The determining means 50 is connected to a time measuring means 53 for measuring the passage of a predetermined time by a counting operation from the initial value. When the detection result indicating that the moving object is not detected is input from the moving object detection unit 41, the determination unit 50 starts the countdown operation from the initial value using the time measuring unit 53. And the determination means 50 will return the counter value of the time measuring means 53 to an initial value, if the detection result to the effect of having detected the moving body is input from the moving body detection part 41 in the middle of countdown operation. On the other hand, if the detection result indicating that the moving object is detected is not input from the moving object detecting unit 41 during the countdown operation and the counter value of the time measuring unit 53 becomes zero, the sound control unit 54 and the illumination control unit 55 receive a sound to be described later. Output and lighting control are executed respectively.

  The activation control unit 12 activates the determination unit 50 when the lighting of the bathroom 3 is turned on. The determination process control unit 52 causes the determination unit 50 to start the abnormality determination process when the moving object detection unit 41 first detects a moving object after the activation control unit 51 activates the determination unit 50. The voice control unit 54, when the determination unit 50 starts the abnormality determination process, when the time when the moving object detection unit 41 does not detect the moving object continues for a predetermined time or more (that is, when the counter value of the time measuring unit 53 becomes zero). In addition, a predetermined sound is output from the sound output unit 15. The illumination control means 55, when the determination means 50 starts the abnormality determination process, when the time when the moving object detection unit 41 does not detect a moving object continues for a predetermined time or more (that is, when the counter value of the time measuring means 53 becomes zero). Next, the illumination state of the illumination unit 11 is changed.

  FIG. 9 is a block diagram showing the configuration of the alarm device 6 shown in FIG. As shown in the connection relationship of FIG. 9, the alarm device 6 includes a communication unit 60, a host device communication unit 61, a processing unit 62, a storage unit 63, an LED 31, a liquid crystal display unit 32, an audio output unit 33, and a stop button 34. It is prepared for. The processing unit 62 is, for example, a CPU. The storage unit 63 is a semiconductor memory, for example, and stores a program 64 for operating the processing unit 62.

  FIG. 10 is a flowchart showing the operation of the detection device 4. When a bath operation is performed, for example, a switch operation for turning on the illumination of the bathroom 3 is performed, the detection device 4 starts its operation.

  First, in step P01, the activation process of the detection device 4 is performed. That is, the power supply unit 40 supplies the power received by the connection unit 12 from the socket 17 to the moving object detection unit 41, the communication unit 42, the processing unit 43, the storage unit 44, the illumination unit 11, and the audio output unit 15. Further, the activation control unit 51 activates the determination unit 50. Furthermore, the communication unit 42 transmits an activation signal indicating that the detection device 4 has been activated to the alarm device 6.

  Next, in step P02, the determination processing control unit 52 determines whether or not the moving object detection unit 41 has detected a moving object after the activation control unit 51 has activated the determination unit 50. When the moving object detection unit 41 does not detect a moving object (that is, when the result of determination in step P02 is “NO”), step P02 is repeated. On the other hand, when the moving object detection unit 41 detects a moving object by opening the door of the bathroom 3 or the like (that is, when the determination result in Step P02 is “YES”), the determination process control means 52 is next performed in Step P03. Causes the determination means 50 to start the abnormality determination process.

  Next, in step P04, the power supply unit 40 determines whether or not a switch operation for turning off the lighting of the bathroom 3 is performed depending on whether or not the power supply from the connection unit 12 is stopped. When the switch operation for turning off the lighting of the bathroom 3 is performed (that is, when the determination result in Step P04 is “YES”), the detection device 4 ends the operation. That is, power supply from the power supply unit 40 to the moving object detection unit 41, the communication unit 42, the processing unit 43, the storage unit 44, the illumination unit 11, and the audio output unit 15 is stopped. On the other hand, when the switch operation for turning off the lighting of the bathroom 3 is not performed (that is, when the result of determination in step P04 is “NO”), in step P05, the determination unit 50 causes the moving object detection unit 41 to move the moving object. It is determined whether or not a time during which no detection is detected continues for a certain time (for example, 30 seconds) or longer.

  If the time during which the moving object detection unit 41 does not detect a moving object does not continue for a certain period of time (that is, if the determination result in Step P05 is “NO”), the process returns to Step P04. Moreover, the communication part 42 transmits the normal signal which shows that abnormality has not generate | occur | produced in the to-be-monitored person to the alarm device 6 regularly (for example, every 5 second interval) by polling. On the other hand, when the time during which the moving object detection unit 41 does not detect a moving object continues for a certain time or longer (that is, when the result of determination in step P05 is “YES”), in step P06, the monitored person is prompted to move. A predetermined warning process is performed. Specifically, the illumination control means 55 changes the illumination state of the illumination unit 11. For example, the illumination is blinked, the amount of illumination light is changed, or the emission color of the illumination is changed. The voice control unit 54 outputs a predetermined voice from the voice output unit 15. For example, a voice message for confirming the safety of the monitored person, a predetermined alarm sound, music, or the like is output from the voice output unit 15. Further, the communication unit 42 transmits a warning signal indicating that the detection device 4 is performing a warning process to the warning device 6.

  Next, in step P07, the determination unit 50 determines whether or not the moving object detection unit 41 has detected a moving object. When the moving object detection unit 41 detects a moving object (that is, when the result of determination in step P07 is “YES”), after the warning process is finished in step P08, the process returns to step P04. On the other hand, if the moving object detection unit 41 does not detect a moving object within a certain time (for example, 15 seconds) after the start of the warning process (that is, if the result of determination in step P07 is “NO”), then step P09 A predetermined alarm process is performed at. That is, while continuing the illumination control and voice control similar to (or more exciting) the warning process, the communication unit 42 sends an alarm signal indicating that the detection device 4 is performing the alarm process to the alarm device 6. Send.

  FIG. 11 is a flowchart showing the operation of the alarm device 6. The alarm device 6 starts operating when the communication unit 60 receives the activation signal transmitted from the detection device 4.

  First, in step Q01, the alarm device 6 is activated. That is, the processing unit 62 causes the LED 31 to light up in green, for example, and causes the liquid crystal display unit 32 to display the characters “being bathed”. Also, polling for status confirmation is started for the detection device 4.

  Next, in step Q02, the processing unit 62 determines whether or not the communication unit 60 has received a signal from the detection device 4. When no signal is received (that is, when the result of determination in step Q02 is “NO”), the alarm device 6 ends its operation. The processing unit 62 turns off the LED 31 and ends the display on the liquid crystal display unit 32. On the other hand, if a signal is received (that is, if the result of determination in step Q02 is “YES”), then in step Q03, processing unit 62 determines whether the received signal is a normal signal or a warning signal. Determine.

  If the received signal is a normal signal, the process returns to step Q02. On the other hand, if the received signal is a warning signal, then a predetermined warning process is performed in step Q04. Specifically, the processing unit 62 lights the LED 31 in red, for example, and causes the liquid crystal display unit 32 to display “warning” characters.

  Next, in step Q05, the communication unit 60 receives a signal next to the warning signal from the detection device 4. Next, in step Q06, the processing unit 62 determines whether the reception signal next to the warning signal is a normal signal or an alarm signal. If the received signal is a normal signal, the warning process is terminated in step Q07, and then the process returns to step Q02. On the other hand, if the received signal is an alarm signal, then in step Q08, a predetermined alarm process is performed. Specifically, the processing unit 62 causes the LED 31 to blink in red, for example, causes the liquid crystal display unit 32 to display “abnormality occurrence” and outputs a predetermined alarm sound from the audio output unit 33. As a result, when there is a monitor (for example, a family member living together) in the house 2, the monitor can rush to the bathroom 3 and check the state of the monitored person. As a result of the confirmation, when the monitored person is safe or the symptom is light, the monitoring person can stop the notification process to the monitoring site 8 by pressing the stop button 34. Thereby, unnecessary emergency dispatch from the monitoring site 8 can be suppressed. Further, as a result of confirmation, even when the lighting of the bathroom 3 is simply forgotten, the notification process can be stopped by pressing the stop button 34 in the same manner. Accordingly, unnecessary emergency dispatch can be suppressed, and a power saving effect can be obtained by turning off the illumination that has been forgotten to be turned off.

  Next, in step Q09, the processing unit 62 determines whether or not the stop button 34 has been pressed after the alarm processing. If the stop button 34 is pressed (that is, if the result of determination in step Q09 is “YES”), the alarm process is then terminated in step Q10, and then the process returns to step Q02. On the other hand, if the stop button 34 is not pressed (that is, if the result of determination in step Q09 is “NO”), then in step Q11, the processing unit 62 starts alarm processing for a certain time (for example, 30 seconds). ) Has passed.

  If the predetermined time has not elapsed since the alarm process was started (that is, if the result of determination in step Q11 is “NO”), the process returns to step Q09. On the other hand, when a predetermined time has elapsed since the alarm process was started (that is, when the result of determination in step Q11 is “YES”), the higher-level device communication unit 61 sends the monitoring site 8 shown in FIG. To report the occurrence of an emergency.

  As described above, according to the detection device 4 and the abnormality monitoring system 1 according to the present embodiment, the connection unit 12 is supplied with power from the socket 17 by being connected to the socket 17 for illumination. The moving object detection unit 41 and the communication unit 42 are driven by the power received by the connection unit 12 from the socket 17. Therefore, even when the detection device 4 is installed in a water environment such as the bathroom 3, power can be supplied by a simple and reliable method. In other words, since it is not necessary to charge or replace the battery regularly, user convenience can be improved. In addition, it is possible to avoid a situation in which an appropriate abnormality notification operation is not performed due to battery exhaustion. Furthermore, the installation cost can be reduced because the wiring work of the feeder line in the water environment is unnecessary.

  In addition, according to the detection device 4 and the abnormality monitoring system 1 according to the present embodiment, the determination unit 50 generates an abnormality in the monitored person in the monitoring area based on the detection result by the moving object detection unit 41. An abnormality determination process for whether or not there is is performed. And the communication part 42 transmits the result (a normal signal, a warning signal, and a warning signal) by the determination means 41 to the alerting | reporting apparatus 6. FIG. Therefore, the raw data of the output signal S1 of the Doppler sensor 411 included in the moving object detection unit 41 or the result of the moving object detection (signal S5) based on the output signal S1 is transmitted to the alarm device 6 and the alarm device 6 receives the monitored person. Compared with the case where the process of determining whether or not an abnormality has occurred, the amount of data transmitted from the communication unit 42 can be reduced.

  However, in an environment where there is a margin in communication capacity, the processing unit 62 of the alarm device 6 has a function as the determination unit 50, and raw data of the output signal S1 of the Doppler sensor 411 included in the moving object detection unit 41, or It is also possible to transmit the result of the moving object detection (signal S5) based on the output signal S1 to the alarm device 6 and perform an abnormality determination process in the processing unit 62.

  In addition, according to the detection device 4 and the abnormality monitoring system 1 according to the present embodiment, the activation control unit 51 activates the determination unit 50 when the illumination of the bathroom 3 (the illumination unit 11 or the illumination 21) is turned on. . Therefore, during the period in which the lighting is turned on (that is, in the period in which the monitored person is present in the monitoring area), the determination unit 50 is reliably activated, so that the monitoring operation of the monitored person is appropriately performed. Can be done. Further, the power consumption can be reduced by not starting the determination means 50 during the period when the illumination is not turned on (that is, within the period when the monitored person is not present in the monitoring area).

  Further, according to the detection device 4 and the abnormality monitoring system 1 according to the present embodiment, the detection device 4 and the illumination 21 are configured by the detection device 4 having the illumination unit 11 as shown in FIG. Compared with the case where and are configured as separate bodies (FIG. 3), the apparatus can be miniaturized. As a result, accommodation in the existing lighting cover 18 is facilitated.

  Moreover, according to the detection apparatus 4 and the abnormality monitoring system 1 which concern on this Embodiment, when using an incandescent lamp and a bulb-type fluorescent lamp by using LED illumination for the illumination part 11 as shown in FIG. Compared with, the illumination part 11 can be reduced in size. As a result, the accommodation in the existing lighting cover 18 is further facilitated.

  In addition, according to the detection device 4 and the abnormality monitoring system 1 according to the present embodiment, the determination processing control unit 52 causes the moving object detection unit 41 to detect a moving object after the activation control unit 51 activates the determination unit 50. Then, the determination unit 50 starts the abnormality determination process. Since the moving object detection unit 41 does not detect a moving object until the monitored person enters the bathroom 3 after the illumination of the bathroom 3 is turned on, by not allowing the determination unit 50 to start the abnormality determination process within this period, An erroneous determination by the determination means 50 can be avoided.

  Further, according to the detection device 4 and the abnormality monitoring system 1 according to the present embodiment, the illumination control unit 55 changes the illumination state when the time when the moving object detection unit 41 does not detect a moving object continues for a predetermined time or longer. Let When the monitored person takes action in response to the change in the lighting state, the moving body detection unit 41 detects the moving body, and the determination unit 50 determines that no abnormality has occurred in the monitored person. be able to. On the other hand, if the moving object detection unit 41 does not detect a moving object because the monitored person does not move even if the lighting state is changed, the determination unit 50 determines that an abnormality has occurred in the monitored person. be able to. Thus, even if the time when the moving object detection unit 41 does not detect a moving object continues for a predetermined time or longer, it is not immediately determined that an abnormality has occurred in the monitored person, but first the lighting state is changed. Accordingly, it is possible to avoid an erroneous determination of the determination unit 50 by prompting the monitored person to perform an operation and determining that the moving object detection unit 41 is abnormal when the moving object detection unit 41 still does not detect the moving object.

  In addition, according to the detection device 4 and the abnormality monitoring system 1 according to the present embodiment, the voice control unit 54 receives the voice output unit 15 from the voice output unit 15 when the moving body detection unit 41 does not detect a moving body for a predetermined time or longer. Predetermined audio is output. When the monitored person takes action in response to the output of the sound, the moving body detecting unit 41 detects the moving body, so that the determination unit 50 can determine that no abnormality has occurred in the monitored person. it can. On the other hand, if the moving object detection unit 41 does not detect a moving object because the monitored person does not take action even if the sound is output, the determination unit 50 can determine that an abnormality has occurred in the monitored person. it can. Thus, even when the time when the moving object detection unit 41 does not detect a moving object continues for a predetermined time or longer, it is not immediately determined that an abnormality has occurred in the monitored person, but a sound is output first. By prompting the monitored person to perform an action, and even when the moving object detection unit 41 still does not detect a moving object, it is determined that there is an abnormality, thereby avoiding an erroneous determination of the determining means 50.

  As a modification, both the detection device 4 and the alarm device 6 are provided with microphones, and voices input from the microphones are bidirectionally communicated via the communication units 42 and 60, so that the person to be monitored in the bathroom 3 and the living room It is good also as a structure which can talk with the supervisor in 5 inside. Thereby, when the occurrence of an abnormal situation is notified to the alarm device 6, the monitor can confirm whether or not the monitored person is safe by conversation.

  FIG. 12 is a diagram illustrating another modification of the detection device 4. The detection device 4 is installed outside the illumination cover 18. In the lighting cover 18, existing lighting 21 is inserted into the socket 17. The existing power supply wiring 81 for connecting the switch of the illumination 21 and the socket 17 is divided in the middle, one end 85 of the divided portion is connected to the detection device 4 via the power supply wiring 82, and the other end 86 is the power supply. It is connected to the detection device 4 via a wiring 83. When the switch of the illumination 21 is turned on, power for lighting the illumination 21 is supplied from the power supply wiring 81 to the illumination 21 through the power supply wiring 82, the detection device 4, the power supply wiring 83, and the socket 17 in this order. Is done. As a result, when the switch of the illumination 21 is turned on, power is also supplied to the detection device 4, and the detection device 4 is activated by the power. In the warning process for prompting the monitored person to move (and the warning process after the warning process), the control device 4 controls the power supplied to the lighting 21 via the power supply wiring 83, thereby controlling the lighting 21. Blink or change the amount of light. In addition, between the one end 85 and the other end 86 of the dividing part of the power supply wiring 81 is connected via an illumination control device including a relay or the like, and the detection device 4 controls the illumination control device by wired communication or wireless communication. It is good also as a structure which controls the state of the illumination 21 by this.
