Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a human body abnormality detection device that detects an abnormal operation state of a person to be detected in a detection space, and particularly relates to the end of detection of an abnormal operation state.
[0002]
[Prior art]
Conventionally, as this type of human body abnormality detection device, for example, a product called “Good Watcher” which is a product name of Nippon Signal Co., Ltd. is known. This product monitors the movement of the detected person in the bathroom or toilet as a detection space, and when the detected person cannot move, asks the detected person "Is it all right?" This is a device for notifying a message or the like and notifying a family member in another room of the abnormality of the detected person in the detection space if there is no response.
[0003]
Specifically, a detection sensor that emits infrared light and detects light reception due to the reflection is provided in the detection space and in the vicinity of the entrance to the detection space, so that the movement of the person to be detected in the detection space and the detection space is detected. It is configured to detect entry / exit. First, the sensor provided in the vicinity of the entrance / exit detects the movement of the motion provided in the detection space by detecting the person entering the detection space. I try to let them. And when the to-be-detected person detects leaving the detection space, the operation of the sensor for detecting the movement of the operation is stopped.
[0004]
[Problems to be solved by the invention]
However, what detects a person to be detected by infrared rays that are received and emitted can be automatically detected and has high detection accuracy, but, for example, when a pet or the like approaches an entrance / exit, detection of an entrance / exit without being noticed by the person to be detected May be erroneously detected. As a result, there is a problem in that even though the person to be detected exists in the detection space, the operation of the sensor that detects the movement of the operation stops, and it becomes impossible to monitor and detect the abnormality.
[0005]
Accordingly, an object of the present invention has been made in view of the above points, and human body abnormality detection that does not cause false detection by disposing a room leaving instruction means for sending out room leaving information by the operation of the person to be detected. A device is provided.
[0006]
[Means for Solving the Problems]
In order to achieve the above object , the technical means described in claim 1 and claim 2 are employed. That is, according to the first aspect of the present invention, the detection means (3a) for detecting the sound in the detection space, the entry detection means (3b) for detecting the entry of the person to be detected into the detection space, and the entry detection Means (3b) detects a person to be detected and starts a monitoring operation. Based on the sound information detected by the means for detection (3a), an abnormality determination control means (8) for determining the abnormal operation state of the person to be detected. A human body abnormality detection device comprising:
A leaving instruction means (6) having an operation unit (6a) for instructing the person to leave the room is provided in the detection space, and the abnormality determination control means (8) is a predetermined time after instructing the operation part (6a). During this period, the determination of the abnormal operation state is continuously performed, and then the determination of the abnormal operation state is ended.
[0007]
According to the first aspect of the present invention, by providing the exit instruction means (6) in the detection space, it is possible to terminate the determination of the abnormal operation state by operating the detected person himself / herself from the detection space. it can. Therefore, it is possible to detect the end of the monitor more reliably based on the will of the detected person than the conventional method of automatically detecting the leaving of the detected person using infrared light receiving and emitting. Thereby, generation | occurrence | production of a misdetection can be prevented.
[0012]
Further, when the exit instruction means (6) is provided in the detection space, it can be confirmed whether or not the detected person can normally exit the detection space after instructing the operation unit (6a). it can. In addition, even if an unexpected accident such as a fall occurs when leaving, it is possible to detect the accident and execute alarm means to be surely notified, thereby providing a safer human body abnormality detection device.
[0013]

[0016]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Hereinafter, a first embodiment of a human body abnormality detection device of the present invention will be described with reference to FIGS. 1 to 3. First, FIG. 1 is a mounting explanatory view of a human body abnormality detection device 1 in which the present invention is applied to a bathroom 2 as a detection space.
[0017]
This human body abnormality detection device 1 includes a remote control panel 3 installed on a wall surface in a bathroom 2 as a detection space, an operation panel 4 installed in a living room or a living room (not shown) outside the bathroom 2 where a person is always present, And an entrance / exit panel 6 which is an exit instruction means installed in the vicinity of the entrance / exit of the bathroom 2.
[0018]
The remote control panel 3 includes a microphone 3a that is a detection unit for monitoring an acoustic waveform as sound information in the bathroom 2, and a distance measurement unit that detects a distance to the detected person as an example of an entrance detection unit. An infrared distance measuring sensor 3b and a notification device 3c for notifying the detected person by a generated signal such as voice are provided.
[0019]
The infrared distance measuring sensor 3b of the present embodiment is a sensor for detecting entry when the person to be detected enters the bathroom 2, and as shown in FIG. 1, the bathroom door 2a, the washing place 2b, It is good to attach to the wall surface arranged in order of bathtub 2c. Moreover, when it is other than this wall surface, it is preferable to arrange | position in the position which can adjust an irradiation direction freely toward the bathroom door 2a.
[0020]
In addition, the notification device 3c is a notification means for notifying the person to be detected by an audio signal such as “Is it all right” or “I'm leaving water” in this embodiment. Further, the microphone 3a is configured to input a sound uttered by the person to be detected and output the sound to a loudspeaker 4b described later, and the alarm 3c is a loudspeaker that outputs a sound from a second microphone 4d described later. It has a function, so that a call can be made inside and outside the bathroom 2.
[0021]
Next, the operation panel 4 includes an operation switch 4a for operating the human body abnormality detection device, a loudspeaker 4b which is an alarm means for alarming the abnormality to the outside when an abnormality occurs in the person to be detected in the bathroom 2, A release switch 4c for releasing the alarm means of the loudspeaker 4b;
A second microphone 4d for calling with the bathroom 2 and a call switch 4e are provided. In the loudspeaker 4b, the sound pressure level value of the alarm sound is set at two levels of at least a low level and a high level.
[0022]
Next, the operation panel 4 is provided with an abnormality determination control means for controlling the alarm 3c and the loudspeaker 4b based on the sound and the signal input related to the body movement input from the microphone 3a and the infrared distance measuring sensor 3b. A certain control device 5 is provided. The control device 5 includes a microcomputer and the like, and is a well-known device having a CPU, a ROM, a RAM, and the like (not shown), and is operated by an operation input of the operation switch 4a of the operation panel 4. It is.
[0023]
The control device 5 is further provided with a first band pass filter 5a as a first filter means and a second band pass filter 5b as a second filter means.
[0024]
Filter the first band-pass filter 5a is a sound generated in the bath 2 is detected by a microphone 3a, extracting specific frequency components by band-pass filter, for _{example, 2000~6000H Z, 5000H Z, 6000H} Z, only such It is. The specific frequency component to be extracted may be extracted by switching at least two or more components, or may be extracted at the same time to detect the presence or absence of a predetermined sound based on the absolute level of the extracted frequency component.
[0025]
Of one, the second band-pass filter 5b, when a call between and bathroom 2 envelope detected person, the voice of the detected person is input to the microphone 3a, the specific frequency component of the example 2000～6000H _Z This is a filter that removes or attenuates, whereby sound cracking or annoying sound caused by reverberation or resonance in the bathroom 2 is removed or attenuated, and a clear sound can be obtained.
[0026]
Next, the entrance / exit panel 6 which is an operation instruction means which is a main part of the invention is operated by operating the exit switch 6a and the exit switch 6a. It is comprised from the output part 6b which outputs leaving information, and the dry battery 6c which is a power supply of the output part 6b. Therefore, the output panel 6 is for outputting the exit information by the user's own operation to determine the intention of the subject to leave.
[0027]
Incidentally, the output unit 6b is for outputting sound or sound as signal sound as the leaving information and causing the microphone 3a of the operation panel 4 to detect it. When the bathroom door 2a of the bathroom 2 is open, the microphone 3a Is configured to detect a signal sound. Therefore, when the bathroom door 2a is closed, even if a person other than the person to be detected operates the operation switch 6a and a signal sound is output from the output unit 6b, the microphone 3a is attenuated by the bathroom door 2a or the bathroom wall. It is made difficult to detect.
[0028]
Specifically, although desirable for the microphone 3a is not easily detected when non when the output as audible frequency band bathroom door 2a of the ultrasonic including a frequency band of several KH _Z a signal sound is closed, these The sound in the frequency band may be superimposed on the sound that can be clearly heard by the detected person such as “Peen! Furthermore, since the output unit 6b can be constituted by a loudspeaker (not shown) and its transmission circuit, it can be covered by a power source of about the dry cell 6c as these power sources. Thereby, the entrance / exit panel 6 can be configured without requiring an electrical connection between the remote control panel 3 and the operation panel 4, and does not require a large installation work.
[0029]
Next, the operation of the human body abnormality detection device 1 having the above configuration will be described based on the flowchart of the control process of the control device 5 shown in FIGS. FIG. 2 shows a control process for determining an abnormal operation state such as when the subject's movement stops due to a cardiac stop or the like in the bathroom 2 which is a detection space, and issuing an alarm. FIG. 3 shows a control process in which the determination of the abnormal operation state is ended by operating the exit switch 6a indicating the exit behavior of the subject himself / herself from the bathroom 2.
[0030]
First, when the person to be detected turns on the operation switch 4a and supplies power to the control device 5 before entering the bathroom 2, the main routine shown in FIG. In step 100, the contents of the data processing memory (RAM) are initialized. In step 110, which is the next occupancy determination means, it is determined whether or not the person to be detected has entered the bathroom 2 by detecting the entry from the infrared distance measuring sensor 3b. Here, when the person to be detected enters the bathroom 2, monitoring is started in step 130.
[0031]
In step 310, a second timer (for example, about 20 to 30 seconds) that does not detect a single sound that closes a door or the like violently, and a third timer (T5, for example, that counts the detection sound generation interval). And a fifth timer (T1, for example, about 1 minute) that counts the silent state until the subject is asked whether there is an abnormality is started.
[0032]
In the next step 320, it is a means for determining hot water supply operation information, and determines whether a hot water supply device (not shown) is operating or stopped to supply hot water in the bathroom. If the apparatus is operated and there is no hot water supply signal, the hot water supply apparatus is stopped.
[0033]
If there is no hot water supply signal, the routine proceeds to step 330, where a first threshold value (L1) for determining the presence or absence of sound after the specific frequency component is extracted by the bandpass filter 5a, and a first timer for determining the duration of this sound. A third predetermined time (T3), which is a time setting, is set. If there is a hot water supply signal, in step 340, a second threshold value (L1) and a sixth predetermined time period (T6) that are greater than the first threshold value (L1) and the third predetermined time period (T3) are set.
[0034]
Here, the first threshold value (L1) and the third predetermined time (T3) are typical sounds generated in the bathroom 2, and the sound generated when hot water moves when the body is moved in the bathtub. , The sound when the vehicle travels outside the bathroom, the sound when the door is closed close to the bathroom 2, the sound of the shower being poured toward the washing place by hooking the shower head on the rack, holding the shower head in hand Thus, it is requested not to be confused by the sound when taking a shower on the body, and detects the sound generated in response to the motion of the detected person in the bathroom 2.
[0035]
In addition, the second threshold (L1) and the sixth predetermined time (T6) are input to the control device 5 from a hot water supply device such as a hot water heater (not shown) to the control device 5 to indicate hot water operation information. It is determined whether or not the hot water supply is in the interior, and it is detected whether the shower or the faucet remains open. Specifically, the person to be detected pours hot water into the bathtub, Since the sound in the bathroom 2 is different when the faucet or shower is opened and the hot water supply operation is performed such as taking a shower in the washing place, the threshold value and the predetermined time are changed.
[0036]
Next, the process proceeds to step 140a of the abnormality determining means for determining the abnormal operation state of the detected person, and it is determined whether or not the first or second threshold (L1, L2) is set. And if it is more than a 1st or 2nd threshold value (L1, L2), it will transfer to the acoustic determination routine 400 for determining whether it is a to-be-detected person's action sound in the bathroom 2 further. Conversely, if it is equal to or less than the first or second threshold (L1, L2), the process proceeds to the processing routine 500 at the time of abnormality.
[0037]
When the detected sound becomes equal to or greater than the first or second threshold (L1, L2), a first timer for duration determination for confirming the duration of the sound is started at step 410. Next, in step 420, it is determined whether or not the third or sixth predetermined time (T3 or T6) for which the first timer has been set is up. When the time is not up, the process returns to step 310 and the sound detection is repeated again. On the other hand, when the time is up, the routine proceeds to step 430, where it is determined whether or not the single sound is invalidated by the second timer.
[0038]
Here, when the second timer is not up, that is, when the silent time is relatively short, the behavior in the bathroom is active, and it should be accompanied by the motion of the detected person in the bathroom. Even if a part of the sound that is not detected is detected, there is no problem from the detection of the abnormal human body. Therefore, the process proceeds to step 450, and the second, fifth, sixth, and seventh timers are reset. That is, it is set here that the detected person is acting.
[0039]
In step 430, if the second timer expires, the detected person has stopped operating for a while. Therefore, if this stoppage of operation is caused by some accident, for example, if an external sound is detected and it is determined that the person to be detected is operating, the alarm is delayed. Therefore, in order to eliminate a single sound that has been detected accidentally for some reason, reconfirmation is performed in the next step 440.
[0040]
That is, in step 440, the third timer has detected the detection sound of the first or second threshold (L1, L2) or more and the third or sixth predetermined time (T3 or T6) or more after the last detection. Time, that is, the detection sound generation interval is determined. Here, if the third timer has timed up, step 450 is not executed as a single sound (the second, fifth, sixth and seventh timers are not reset), in other words, the subject to be detected. It is determined that is not in operation, and only reset of the first and third timers in step 460 is executed.
[0041]
Next, the process proceeds to steps 470, 480 and 490. In these steps, if a detection sound is detected once more than the first or second threshold (L1, L2) and the third or sixth predetermined time (T3 or T6), the fourth predetermined time (T4, for example, 1) The next acoustic detection is stopped for about a second). In order to capture them as a single sound, even if it is a single sound when the door is closed violently or analyzed at an extremely short time level, it becomes a plurality of sound groups with several peak values. Execute. Thereafter, the process returns to step 310 to repeat the sound monitoring.
[0042]
Next, the processing routine 500 at the time of abnormality will be described. First, in step 510, the first timer for duration determination is reset. Next, the process proceeds to step 140b of the abnormality determining means, and the duration of the silent state is confirmed by the fifth timer. Here, if the fifth timer has not timed out, it is determined that the abnormal state has not been reached, the process returns to step 310, and the acoustic monitoring is repeated.
[0043]
On the other hand, if the fifth timer has expired, the process proceeds to step 150a, which is the next notification means. For example, an abnormality is detected in the detected person by an audio signal such as "Is it all right" or "How was it?" The 6th timer starts counting the response time waiting time for the inquiry. Since this interrogation is intermittently performed, the detection of sound may be interrupted during the interrogation, and the response from the detected person may be determined between the interrogation.
[0044]
It is assumed that the specific frequency component extracted by the first band pass filter 5a from the audio signal used for this inquiry is removed or attenuated in advance. Thereby, it is possible to obtain accurate sound information even when the notification sound in the bathroom is not erroneously determined as the operation sound of the person to be detected and the notification is being performed.
[0045]
Next, the process proceeds to step 160a, which is a response determination unit, and the presence or absence of a response from the detected person is determined. Here, if there is a response but before the sixth timer expires, the process returns to step 310 to repeat the sound monitoring. If there is a response, the sound determination routine 400 described above determines that there is a response.
[0046]
Then, when the sixth timer expires, it is determined that there is no response from the detected person at a sixth predetermined time (for example, about ten and several seconds), and the process proceeds to step 180 which is an alarm means. In this step 180, while continuing to ask the person to be detected, the person in the living room outside the bathroom 2 is warned that an abnormality has occurred in the person to be detected. In the initial stage, the warning is generated by the loudspeaker 4b with an output signal of a small level. At the same time, it starts counting a determination-waiting seventh timer (for example, about a dozen seconds or more) for determining whether or not this alarm has been taken.
[0047]
And if the 7th timer of step 190a times out, it will determine with the treatment with respect to a to-be-detected person's abnormality not being performed, and will transfer to step 200 which is the next warning means. In step 200, the person to be detected is continuously inquired, and an alarm in the person outside the bathroom 2 that an abnormality has occurred in the person to be detected continues to be output with an output signal having a level higher than that in step 180. Migrate to In step 210, it is determined whether a release operation has been performed with the release switch 4c. If there is no release operation, the process returns to step 200 and continues to issue an alarm. If a release operation is performed, the process returns to step 100. The above is the control processing for determining the abnormal operating state of the person to be detected, and is the same as that described in Japanese Patent Application No. 2002-5972 filed earlier by the inventors.
[0048]
Next, when the detected person leaves the bathroom 2, in this embodiment, the detected person himself / herself operates the exit switch 6 a of the entrance / exit panel 6 to stop the monitor. The control process of the control apparatus 5 at this time outputs a signal sound as exit information from the output unit 6b of the entrance / exit panel 6 when the detected person operates the exit switch 6a. The signal sound is detected by the microphone 3a in the remote control panel 3 to end the determination of the abnormal operation state of the person to be detected.
[0049]
Specifically, as shown in FIG. 3, first, in step 600, the person to be detected opens the bathroom door 2a and operates the exit switch 6a. Accordingly, in step 610, the exit information is emitted from the output unit 6b as a signal sound, for example, “Peen! At this time, since the bathroom door 2a is open, the microphone 3a in the bathroom 2 detects this signal sound.
[0050]
In the next step 620, it is determined whether or not there is an acoustic signal as the leaving information. If there is an acoustic signal, the monitor is stopped in step 630. Thereby, the determination of the abnormal operation state is terminated. However, when the exit switch 6a is operated after the bathroom door 2a is closed, if the acoustic signal output from the output unit 6b cannot be detected by the microphone 3a, it is determined that there is no acoustic signal and the monitor is monitored in step 640. It is supposed to continue.
[0051]
However, since there is no person to be detected in the bathroom 2 at this time, it is determined that the state is substantially silent, and the alarm is continued to be issued in step 200 through the processing routine 500 at the time of abnormality described above. Further, when the detected person forgets to operate the exit switch 6a, the alarm is continuously output in step 200 as described above.
[0052]
According to the human body abnormality detection device 1 of the first embodiment described above, the operation switch 6a that instructs the entrance / exit panel 6 to leave the detected person and the output unit 6b that outputs a signal sound as the exit information are provided. By detecting the signal sound output from the output unit 6b and ending the determination of the abnormal operation state, the monitor can be reliably ended by the operation of the person to be detected himself / herself leaving the room. Accordingly, detection based on the will of the person to be detected can be performed without causing erroneous detection and using conventional infrared light receiving and emitting and automatically detecting the person leaving the room to be detected.
[0053]
In addition, by configuring the entrance / exit panel 6 from the operation switch 6a and the output unit 6b, for example, when a dry battery 6c or the like is used as a power source of the output unit 6b, the electrical wiring can be made wireless, so that the size and weight can be reduced. The construction can be simplified to the extent that even an amateur can install it.
[0054]
Further, when the bathroom door 2a is opened, by outputting the exit information by the signal sound from the output unit 6b, for example, if the non-audible frequency band, such as ultrasonic wave including a frequency band of several KH _Z, If the bathroom door 2a is closed, even if a person other than the person to be detected operates the operation switch 6a, the bathroom door 2a is attenuated by the bathroom door 2a and the bathroom wall, so that it is difficult to detect by the microphone 3a, thereby preventing erroneous detection.
In addition, by detecting that the microphone 3a is in a substantially silent state and determining the abnormal operation state of the person to be detected, the acoustic sound is louder in a closed space or in a narrow space, and outside the detection space. The sound that enters through the air easily attenuates due to propagation in the air and permeation through the wall surface, so the presence or absence of sound can be easily detected. In particular, when applied to a dark room or a bathroom where steam is generated, the detection accuracy is superior to that of an image using a camera.
[0055]
(Second Embodiment)
In the first embodiment described above, the entrance / exit panel 6 serving as an exit instruction means is provided in the vicinity of the entrance / exit of the bathroom 2. However, the present invention is not limited thereto, and the remote control panel is provided in the bathroom 2 or in the bathroom 2. 3 may be provided.
[0056]
Furthermore, although the output part 6b was provided in the entrance / exit panel 6 and the signal sound was output as the exit information output from the output part 6b, the exit signal was electrically connected as the exit information based on the instruction of the operation switch 6a. Alternatively, it may be output to the control device 5. Specifically, as shown in FIG. 4, an operation switch 6 a as an operation unit is provided in the remote control panel 3, and is connected so that an exit signal from the operation switch 6 a is output to the control device 5. However, at this time, if the detected person finishes the determination of the abnormal operation state immediately after operating the operation switch 6a, an abnormality such as a fall before the detected person leaves the bathroom 2 can be detected. There is a problem that disappears.
[0057]
Therefore, in the present embodiment, a control process is provided for determining whether or not the bathroom 2 is reliably left after the detected person operates the operation switch 6a. Specifically, as shown in FIG. 5, when the exit switch 6a of the detected person is turned on (step 700), in step 710, the eighth predetermined time (T8) of the eighth timer and the ninth timer of the ninth timer are set. The predetermined time (T9) is reset and the monitor end process is started.
[0058]
Next, the process proceeds to step 720 to determine whether there is an acoustic signal. If there is no acoustic signal, the process proceeds to step 730 to start the count of the eighth timer. If the time of the eighth timer is not up in the next step 740, the process returns to step 720 and waits for detection of the acoustic signal. . If the eighth timer has expired, the room has not been normally exited. That is, it is determined as an abnormal operation state, and an alarm unit is executed in step 200.
[0059]
On the other hand, when an acoustic signal is detected in step 720, the process proceeds to step 760, for example, an inquiry such as “Did you leave the room” and the process proceeds to step 770. The acoustic signal detected in step 720 is, for example, a sound generated when the bathroom door 3a is opened, and is determined to be a normal exit. Next, at step 770, the presence or absence of a response is determined. The response may be a sound generated when closing the opened bathroom door 3a. Also, a voice such as “I got out” may be used. If there is no response in step 770, the process proceeds to step 780 to start counting the ninth timer. If the time of the ninth timer is not up in the next step 790, the process returns to step 770 and Wait for a response from the detector. And if the 9th timer has timed up, it has not left the room normally. That is, it is determined as an abnormal operation state, and an alarm unit is executed in step 200. If there is a response in step 770, it is determined that the room has been successfully exited, and the monitor is terminated in step 630.
[0060]
According to the above embodiment, even after the exit switch 6a is operated, the monitor is continued for a predetermined time, and the exit of the exit switch 6a is confirmed by terminating the monitor after confirming that the exit is normal. Even if an unexpected accident occurs later, it is possible to detect the accident and execute a warning means to reliably notify it, thereby providing a safer human body abnormality detection device.
[0061]
(Other embodiments)
In the above embodiment, the step 150a as the notification means is interrogated by the voice signal to the person to be detected in the bathroom 2, but may be notified as a warning sound. And you may make it comprise so that this warning sound may emit to the bathroom 2 outer side. As a result, it is possible to take all possible measures as a predictive warning of an abnormality to a person existing outside the bathroom 2.
[0062]
Moreover, in the above embodiment, it demonstrated using the infrared distance measuring sensor 3b which is a distance measuring means which detects the distance to a to-be-detected person as an entrance detection means to detect a to-be-detected person's entrance into the bathroom 2. FIG. However, the present invention is not limited to this, and the entry of the person to be detected may be detected by detecting a manual start switch of the monitor, an opening / closing signal of the bathroom door 2a, a passing signal of the person to be detected, a lighting switch of the bathroom 2, and the like. Furthermore, in the bathroom 2, the entry of the person to be detected may be detected by detecting a start signal of flowing water from a hot water tap provided in the shower or bathroom.
[0063]
Further, the sound of the person to be detected input to the microphone 3a is output from the loudspeaker 4b after the specific frequency component is removed or attenuated by the second bandpass filter 5b, so that the sound or resonance in the bathroom 2 is output. Clear sound can be obtained by removing or attenuating sound cracks and unpleasant sounds caused by sounds.
[0064]
Moreover, although the microphone 3a, the infrared distance measuring sensor 3b, and the alarm device 3c are disposed in the remote control panel 3, they may be incorporated in a remote control panel such as a hot water supply apparatus that supplies hot water to the washing place 2b or the bathtub 2c. Thereby, the additional function of a hot-water supply apparatus improves.
[0065]
Moreover, although the above embodiment demonstrated the human body abnormality detection apparatus 1 applied in the bathroom 2, it is not restricted to this, As detection space for the human body abnormality detection which is this invention, a washroom, a toilet, or The present invention may be applied to a living room for a detected person who needs care such as an aged room.
