The biological vibration sensor notification device of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an outline of a device configuration in the embodiment. The porous polypropylene electret film 20 of the biological vibration sensor means 10 has a structure in which an infinite number of holes are formed inside a polypropylene polymer film, and a high voltage discharge is further applied to accumulate charges in the holes. An electrode terminal is configured by sandwiching both surfaces of the film with a conductive sheet, a conductive paste, or the like. When pressure is applied to the surface of the film, a voltage is generated at the electrode terminal. In a state in which a person touches the porous polypropylene electret film 20 directly or through an object, vibration due to heart beat, vibration due to lung respiration, and vibration due to body movement can be detected as a change in voltage. . The detected vibration is output as an “oscillating voltage signal” which is an electrical signal. The “oscillating voltage signal” is amplified by the signal amplification amplifier unit 30 as necessary.

The presence / absence detection means 300 detects the pulsation of the heart and the vibration due to lung respiration to distinguish between a living body and an object, and senses the presence or absence of a person. The analog comparator 310 compares and determines the positive voltage “existing reference voltage” by the presence reference voltage generator 210 of the presence reference voltage setting means 200 and the positive voltage output range “oscillating voltage signal”. "Vibration voltage signal" is greater than or equal to "existence reference voltage" and detection that a person is "present", and "oscillation voltage signal" is less than or equal to "existence reference voltage" and a person is "absence" To detect. Further, in the output range where the “oscillating voltage signal” is a negative voltage, it is compared with the “existence reference voltage” of the negative voltage.

The motion stationary detection means 400 senses the motion and stationary state of a person by detecting vibration due to body movement. The analog comparator 410 compares and determines the positive “movement reference voltage” by the movement reference voltage generator 230 of the movement reference voltage setting means 220 and the “oscillating voltage signal” in the output range of the positive voltage. "Vibration voltage signal" is greater than or equal to "exercise reference voltage" and detection that a person is "exercising", and "oscillation voltage signal" is less than or equal to "exercise reference voltage" and a person is "still" To detect. Further, when the “oscillating voltage signal” is in the negative voltage output range, it is compared with the negative “motion reference voltage”. "Vibration voltage signal" is less than "exercise reference voltage" and detection that the person is "exercising", and "oscillation voltage signal" is more than "exercise reference voltage" and the person is "still" To detect.

The presence reference voltage setting means 200 causes the presence reference voltage generator 210 to generate a reference voltage of “existence reference voltage”. The presence reference voltage generator 210 is a D / A converter that generates an analog voltage under the control of the processing CPU unit 510 based on the presence reference voltage value data stored in the program storage memory unit 520 of the notification determination processing unit 500. It has a function.

The motion reference voltage setting means 220 generates a reference voltage of “motion reference voltage” with the motion reference voltage generator 230. The motion reference voltage generator 230 is a D / A converter that generates an analog voltage under the control of the processing CPU unit 510 based on the motion reference voltage value data stored in the program storage memory unit 520 of the notification determination processing unit 500. It has a function.

The vibration sound reference voltage setting means 240 causes the vibration sound reference voltage generator 250 to generate a reference voltage of “vibration sound reference voltage”. The motion reference voltage generator 250 is a D / A converter that generates an analog voltage under the control of the processing CPU unit 510 based on the motion reference voltage value data stored in the program storage memory unit 520 of the notification determination processing unit 500. It has a function.

In the notification determination time setting means 100, the processing CPU unit 510 of the notification determination processing means 500 force-sets the “notification determination time value” required for the notification comparison determination processing. The “notification determination time value” is set using a setting switch or the like under the control of the notification processing CPU unit 510. The contact state of the switch is read by the processing CPU unit 510 and taken into the program storage memory unit 520 as “report determination time value” data. In addition, the setting switch can be omitted by writing the “report determination time value” data in advance in the program storage memory unit 520 of the report determination processing unit 500.

Pre-bell duration setting means 110 is a processing CPU section 510 of notification determination processing means 500 for inputting and setting a “pre-bell continuous permissible time value” required for notification comparison determination processing. The “pre-bell allowable time value” is set using a setting switch or the like under the control of the processing CPU unit 510. The contact state of the switch is read by the processing CPU unit 510 and taken into the program storage memory unit 520 as “pre-bell continuous permissible time value” data. Further, the setting switch can be omitted by writing the “pre-bell continuous continuation time value” data in advance in the program storage memory unit 520 of the notification determination processing unit 500.

The notification determination processing means 500 compares and determines the durations of “present” and “still” based on the “notification determination time value” in the processing CPU unit 510, and more than the “notification determination time value” and “ Based on the “report determination time value”, the duration of “absence” is compared and determined, and a determination process is made to report on a condition equal to or greater than the “report determination time value”. Prior to issuing the report, a bell will be issued to inform the parties that the report will be issued. When “exercising” is detected while the bell is continuously issued to the “pre-bell allowable time value”, the bell and the notification are canceled and the determination process is performed again. The condition for this determination process is that a notification is issued when “still” or “not present” continues for a specified time on the assumption that there is always a human body movement.

In another determination processing condition, the notification determination processing unit 500 uses the processing CPU unit 510 to compare and determine the duration of “exercising” based on the “notification determination time value” and to determine the “notification determination time value”. Judgment processing to make the above notification is performed. Prior to issuing the report, a bell will be issued to inform the parties that the report will be issued. If “resting” is detected while the bell is continuously issued to the “pre-bell permissible time value”, the bell and the notification are canceled and the determination process is performed again. The condition for this determination process is that the person's body is always stationary, and a notification is issued when “exercising” continues for a specified time. The determination processing conditions are set in the operation software program in the program storage memory unit 520.

The notification bell output means 600 outputs a bell, a bell sound, a notification sound, and a notification light using any one of the bell, sound from the buzzer speaker 610, LED 620, and the like. The pre-bell outputs a sound different from the notification sound, a sound that makes the notification sound shift from a low volume to a high volume, a voice, a message guidance sound, and the like.

The vibration AD conversion unit 700 converts an analog signal of the “vibration voltage signal” into a digital signal and generates “vibration digital data”. The “vibration digital data” is substituted for the presence / absence detection unit 300 by the determination determination unit 500 comparing the “existence reference voltage” with the “vibration voltage signal”. Further, by comparing and determining the “movement reference voltage” and the “oscillating voltage signal”, the movement stationary detection means 400 is substituted. Transmission by the communication transmission means 900 can be used for safety confirmation or information analysis from a remote location.

The biological vibration sound generation means 800 represents the state of human vibration with sounds in the audible sound region. The “vibration sound reference voltage” and the “vibration voltage signal” are compared and determined, and the “biological vibration sound” in the audible sound region is generated at the “vibration sound reference voltage” or more. This “biological vibration sound” is transmitted to a remote place by the communication transmission means 900 to confirm the safety of the person. Also, it can be heard through the buzzer speaker 610 for confirmation of the vibration detection status.

The external signal input / output unit 1000 serves as a data information transfer port when operating in conjunction with another biological vibration sensor notification device. It also serves as an accepting port for connections such as external switches.

The communication transmission means 900 transmits the bell sound, the notification sound, the biological vibration sound, etc. through the communication through the telephone line or the wireless device, or transmits the vibration digital data by the transmission procedure such as TCP / IP or start / stop synchronization. Therefore, the data of the notification and “vibration voltage signal” are used for remote use or confirmation of safety.

The start and end of the operation of the biological vibration sensor notification device is performed by turning on / off the device power switch. When the device is in operation, turning on / off the external switch connected to the external signal input / output unit 1000 May be used as control signals for operation interruption and operation resumption.

FIG. 2 is a diagram illustrating the relationship between absence and presence of motion in the embodiment. The relationship between `` oscillating voltage signal '' in presence absence detection means, motion stationary detection means, notification determination processing means and duration of `` existing '' `` absent '' `` exercising '' `` stationary '' and `` stationary '' Show.

FIG. 3 is a diagram illustrating an outline of operation in the embodiment. A bio-vibration sensor reporting device is installed in the “toilet” to detect and report changes in human health. By installing the “biological vibration sensor means” at the feet in front of the toilet, even when sitting on the toilet or using the stool while standing, the “biological vibration sensor means” is always in contact with the person.

The start and end of the operation of the biological vibration sensor notification device is performed by turning on / off the device power switch when entering and leaving the “toilet”. However, in situations where the device power switch operation tends to be forgotten, it is possible to grasp the entrance / exit while the biological vibration sensor reporting device is in operation. Get from. For example, a door opening / closing detection switch or the like is attached to the door, and the door opening / closing signal is grasped by fetching from the “external signal input / output unit 1000 (FIG. 1)” of the biological vibration sensor notification device. Confirmation of entry into the “toilet” is that a person has entered the “toilet” by detecting the presence / absence detection means and “exercising” by the motion detection detection means following the door open / close signal. Judge. Confirmation of leaving the room from the “toilet” determines that the user has left the room by continuously outputting “not stationary” and “not present” together with a door opening / closing signal.

In the detection of health change, in a healthy state, “present” and “exercising” are continuously output as the body moves during the stool. When the health changes, the movement of the body stops, the heart and lungs stop breathing, or falls, and the "biological vibration sensor means" leaves. As a result, “not present” or “present” and “still” are continuously output. By comparing and comparing these elapsed times and the “report determination time value” set in advance, a report is made as a health change.

However, even in a healthy state, the state of quiet movement of the body sometimes continues, and “stillness” is continuously output, and it is judged that the health has changed and a notification is issued. Therefore, in order to determine again whether the health has changed or is in a healthy state, the person concerned is informed with a pre-bell before making a sound. If the person who listens to the pre-bell sound is in a healthy state, the body is consciously moved to cancel the generation of the pre-bell sound and the notification sound. If it is a state of health change, it is judged that the state of health has changed due to conscious movement of the body or no movement, and a notification sound is emitted.

If the door open / close signal cannot be acquired due to the condition that the door of the “toilet” is left open, the door is not present, or the door open / close detection switch cannot be installed, the “biological vibration” A bio-vibration sensor notification device provided with “sensor means” is added. The entry / exit of the room is confirmed by connecting and interlocking with the biological vibration sensor notification device in the “toilet” room and the “external signal input / output unit 1000 (FIG. 1)”. When a person enters the toilet, the living body vibration sensor reporting device at the entrance senses, and when the person moves and enters the room, there is no sensing at the entrance and the living body vibration sensor reporting device in the room senses it. To enter the room. At the time of leaving the “toilet”, the detection by the living body vibration sensor notification device in the room disappears, and it is determined by the detection by the living body vibration sensor notification device at the entrance. Thereby, the direction of movement and the state of entering and leaving the “toilet” can be grasped.

FIG. 4 is a diagram illustrating an outline of operation in the embodiment. A biological vibration sensor reporting device is installed in the “bathroom” to detect and report human health changes. The “biological vibration sensor means” is installed in a washing place or a bathtub. When installed and operated on both sides, each other's biological vibration sensor reporting device is connected and linked. The start and end of the operation of the biological vibration sensor notification device is performed by turning on / off the device power switch when entering or leaving the “bathroom”. However, in situations where the device power switch operation tends to be forgotten, the entry / exit of the room while the biological vibration sensor notification device is in operation is ascertained by using a door opening / closing detection switch or the like in the same manner as the “toilet”. Alternatively, the entry / exit of the room can be confirmed by adding a biological vibration sensor notification device in which “biological vibration sensor means” is installed at the foot of the entrance as in the “toilet”. In the health change detection, “not present” or “present” and “still” are continuously output as in the operation of the “toilet”. By comparing and comparing these elapsed times and the “report determination time value” set in advance, a report is made as a health change. It is also the same as the operation of the “toilet” to notify the parties themselves with a pre-bell before making a notification sound.

“Safety confirmation” transmits “biological vibration sound” to a remote place using a telephone line, a wireless communication device or the like. A remote person can confirm the safety by listening to the “biological vibration sound”. The biological vibration detection notification device can be installed in places where people stay, such as a toilet, bathroom, bed, living room, chair, seat seat, and the like.

FIG. 5 is a diagram illustrating an outline of operation in the embodiment. A biological vibration sensor reporting device is installed in the “bed” to detect and report human health changes. The start and end of the operation of the biological vibration sensor notification device is performed by turning on / off the device power switch. In the detection of health changes, “absent” is continuously output. By comparing and comparing these elapsed times and the “report determination time value” set in advance, a report is made as a health change.
