A living body sensing vibration sensor 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. The porous polypropylene electret film 20 is also represented by the name of an EMFi film (ElectroMechanical Film). In a state in which a person is in contact with 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.

"Vibration voltage signal" is equal to or higher than "exercise reference voltage value", detection that a person is exercising, and "Vibration voltage signal" is less than "exercise reference voltage value" to detect that a person is stationary Then, the “motion stationary signal” is output.

The presence reference voltage setting means 200 causes the presence reference voltage generator 210 to generate a reference voltage of “existence reference voltage value”. The presence reference voltage generator 210 has a D / A converter function for generating an analog voltage by controlling a digital signal. The input setting of the “existing reference voltage value” is set using a setting switch or the like under the control of the central processing CPU unit 600. The central processing CPU section 600 reads the contact state of the switch and loads it into the program storage memory section 610 as “existing reference voltage value” data. In addition, the setting switch can be omitted by writing the “existence reference voltage value” data in the program storage memory unit 610 in advance.

The motion reference voltage setting means 220 causes the motion reference voltage generator 230 to generate a reference voltage of “motion reference voltage value”. The motion reference voltage generator 230 has a D / A converter function for generating an analog voltage by controlling a digital signal. The input setting of the “movement reference voltage value” is set by using a setting switch or the like under the control of the central processing CPU 600.

The bell is emitted by a sound different from the notification sound, a sound that shifts the notification sound from a low volume to a high volume, a voice, a message guidance sound, and light. The continuation time of the warning bell continues until the time corresponding to the “pre-bell allowable time value” by the warning bell time setting means 120 to issue the warning bell. If the notification determination condition in the notification determination processing means 700 is canceled while a warning bell is being issued, the warning bell and the notification are stopped. If the judgment condition is not canceled, a notification sound or a notification light is subsequently emitted.

The input setting of the “pre-bell continuation allowable time value” in the pre-bell time setting means 120 is set by using a setting switch under the control of the central processing CPU unit 600. The central processing CPU unit 600 reads the contact state of the switch and loads it into the program storage memory unit 610 as “pre-bell continuous permissible time value” data. In addition, the setting switch can be omitted by writing data of “pre-bell continuous continuation time value” in advance in the program storage memory unit 610 of the central processing CPU unit 600.

The AD conversion unit 800 converts an analog signal of the “vibration voltage signal” into a digital signal and generates a “biological vibration digital signal”. The “biological vibration digital signal” is compared with the “existence reference voltage value” by the central processing CPU unit 600 and is used as an “existence absence signal” to replace the presence / absence detection means 300. Further, by comparing with the “movement reference voltage value” and making “movement stationary signal”, the movement stationary detection means 400 is substituted. Furthermore, the “biological vibration digital signal” is stored in the biological vibration information storage unit 500, so that it can be used later for vibration information analysis.

For example, a door opening / closing detection switch or the like is attached to the door, and the door opening / closing signal is captured by “external signal input / output unit 1000 (FIG. 1)” of the biological detection vibration sensor device. Confirmation of entry to the “toilet” is that a person has entered the “toilet” by detecting a “presence absent signal (during presence)” or “exercise stationary signal (during exercise)” following the door opening / closing signal. to decide. Confirmation of leaving the room from the “toilet” determines that the user has left the room by continuously outputting a “presence absent signal (not present)” and an “exercise stationary signal (not stationary)” together with a door opening / closing signal.

In the detection of a health change, in a healthy state, the body moves during the stool, so that a “presence absent signal (present)” and an “exercise stationary signal (exercise)” are continuously output. In a health change, the movement of the body stops, the heart or lungs stop breathing, or the fall from the “biological vibration sensor means” occurs due to falling. As a result, a “presence absent signal (during absence)” or “motion stationary signal (static)” is continuously output. By comparing and comparing the elapsed time of these signals with the preset “allowable elapsed time value”, “allowable absence time value”, “allowable static time value”, and “allowable motion time value”. , Issue a report as a health change.

However, even in a healthy state, sometimes the state of quiet movement of the body continues, and an “exercise stationary signal (stationary)” is continuously output, and it is determined that the health has changed, and a report is issued. Therefore, in order to re-determine one of the health changes, the person himself / herself is informed with a pre-bell before making a notification 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 there is a health change, the body will not move consciously, or it will not move.

If the door opening / closing 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 sensor” A biological sensing vibration sensor device provided with "means" is added. The living room sensing vibration sensor device in the “toilet” room and the “external signal input / output unit 1000 (FIG. 1)” are connected to each other and interlocked to confirm entry / exit. When a person enters the “toilet”, the living body sensing vibration sensor device at the entrance first senses, and then when the person moves and enters the room, there is no sense at the entrance, and the living body sensing vibration sensor device in the room It is judged that it is entering the room by being detected. When leaving the "toilet", the detection by the living body sensing vibration sensor device in the room disappears, and it is determined that the user has left the room by being detected by the living body sensing vibration sensor device at the entrance. Thereby, the direction of movement and the state of entering and leaving the “toilet” can be grasped.

However, in situations where it is easy to forget to operate the device power switch, the entry / exit of the device while the device is operating is grasped by using a door opening / closing detection switch or the like, as in the case of the “toilet”. In addition, as with the “toilet”, entering and leaving the room can be confirmed by adding a bio-sensing vibration sensor device in which “biological vibration sensor means” is installed at the foot of the entrance. In the detection of health changes, as with the operation of the “toilet”, the output elapsed time based on the “presence absent signal” or “exercise stationary signal” and the preset “presence elapsed allowable time value”, Notification is made by comparison with the “absent elapsed allowable time value”, “still elapsed allowable time value”, and “exercise elapsed allowable time value”. It is also the same as the operation of the “toilet” to notify the person with a pre-bell before making a notification sound.
