DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dynamic detection system 1 according to a preferred embodiment of the present invention will be described below with reference to FIGS.

First, the installation configuration of the dynamic detection device 10 will be described with reference to FIG. FIG. 1 is an external view showing an example in which a movement detection device 10 according to the present invention is applied to a bed 2. The movement detecting device 10 includes two upper optical sensors 11, 11, 2
It comprises pressure-sensitive sheets 12, 12 and a lower optical sensor 13.

As shown in FIG. 1, on the head board 2c of the bed 2, upper optical sensors 11, 11 are provided independently at two places at the center of the upper end of the side surface of the mat so that light can be projected in the longitudinal direction of the bed 2. It is arranged like. The pedestal 2b has two tape-shaped pressure-sensitive sheets 12, 1 on both side edges on a plane.
2 are laid along the longitudinal direction of the bed 2. A mat 2 having substantially the same shape as the pedestal 2b is provided on the upper layer of the pedestal 2b.
a is placed. Further, lower optical sensors 13 and 13 are installed at two places near the corners of the bed 2 on the wall surface in contact with the head board 2c so as to project light in the longitudinal direction of the bed 2.

Next, the internal configuration of the dynamic detection device 10 will be described with reference to FIG. FIG. 2 is a block diagram showing a functional configuration of the movement detection system 1 configured using the movement detection device 10 according to the present invention. As shown in FIG. 2, the movement detection system 1 includes a movement detection device 10, a transmission device 20,
The main part is composed of the output unit 30. Further, the dynamic detection device 1
Numeral 0 is composed of two upper optical sensors 11, 11, two pressure-sensitive sheets 12, 12, and lower optical sensors 13, 13. The upper optical sensor 11 includes a light projecting unit 11a and a light receiving unit 11b.
, And the lower optical sensor 13 includes a light projecting unit 13a and a light receiving unit 13b.

The upper optical sensor 11 is a reflection type human sensor that constantly emits a weak light beam L1. Upper light sensor 1
1 has a light emitting part 11a and a light receiving part 11b inside. The light projecting unit 11a projects the light beam L1 from the sensor side in a direction perpendicular to the installation surface of the sensor, and the light receiving unit 11b receives the reflected light and measures the distance to the human body. Here, when the human body exists within a predetermined distance, a detection signal is transmitted to the transmission device 20. The output timing of the external trigger signal is variably set so that the upper optical sensors 11 do not interfere with each other.

By forming a single upper optical sensor 11 and rotating it by a predetermined angle using a plane parallel to the bed installation surface (floor surface) as a rotation surface, a fan-shaped light beam slice surface is formed on the bed 2. Then, the caregiver may be configured to detect the long sitting position.

The pressure-sensitive sheet 12 is a tape-shaped pressure-sensitive sensor composed of a piezoelectric member having a one-dimensional piezoelectric effect. The pressure-sensitive sheet 12 transmits a detection signal to the transmission device 20 when detecting a load equal to or more than a predetermined value downward with respect to the installation surface. Note that the pressure-sensitive sheet 12 may be of any type that uses a flat surface or a curved surface, or may have a shock absorbing function. The lower optical sensor 13 is a reflection-type human sensor configured similarly to the above-described upper optical sensor 11, and has a light projecting unit 13a and a light receiving unit 13b inside.

The pressure-sensitive sheets 12, 12 and the lower optical sensors 13, 13 may be provided one by one on one side of the care-receiver's floor. Thereby, the dynamic detection system 1 can be configured simply and at low cost.

The transmission device 20 includes a control unit 21 and an input unit 2
2. It is composed of a storage unit 23 and a transmission unit 24, and each unit is connected by a bus. The control unit 21 controls each unit of the transmission device 20 in a unified manner. When a sensor signal detected as reflected light from the dynamic detection device 10 is input to the input unit 22, the upper light sensor 11, the pressure-sensitive sheet 12 Then, the dynamics of the care receiver are determined by the combination of the lower light sensor 13.

Next, the control section 21 generates a dynamic signal based on the result of the determination. That is, if no detection signal is received, a dynamic signal of “sleeping posture (lying posture)” is generated, and if only the detection signal of the upper optical sensor 11 is received, “long sitting position (only the upper body Posture) "dynamic signal. When the detection signals of the pressure-sensitive sheet 12 and the lower optical sensor 13 are received after the detection signal of the upper optical sensor 11 is released, a dynamic signal of “end sitting position (posture sitting on the bed end)” is generated. When the detection signal of the pressure-sensitive sheet 12 is cancelled, a dynamic signal of “standing (a posture standing beside the bed)” is generated. Further, thereafter, the lower light sensor 13
When the detection signal is released, a dynamic signal of “walking start” is generated.

Further, the control unit 21 transmits the dynamic signals to the output unit 30 in order to transmit the dynamic signals to the output unit 30.
The telephone number data of S31 is read. The transmission unit 24 automatically transmits the dynamic signal to a PHS 31 (to be described later) corresponding to the read telephone number data, based on the setting of the notification destination button (not shown). If the PHS 31 cannot receive the dynamic signal due to a line failure, congestion, or the like, the transmission unit 24
Switches the transmission destination of the dynamic signal to the pager 32. Further, when the pager 32 cannot receive the dynamic signal, the transmission unit 24 switches the transmission destination of the dynamic signal to the nurse call 33. The transmission of the dynamic signal by the transmission unit 24 is executed as needed each time the dynamic signal is generated by the control unit 21.

Further, the control unit 21 determines whether or not the dynamic state is continued. That is, after the detection signal is received from the dynamic state detection device 10, it is determined whether or not the detection signal has been received after a lapse of a predetermined time (for example, 5, 10, 20 seconds), and only when the detection signal is received again, the corresponding process is performed. Generate and transmit dynamic signals. In addition,
The control unit 21 may be configured to determine the presence or absence of the detection signal at an interval of one second as needed, and determine the continuation of the dynamic state based on the count value of the number of consecutive times.

And the like.

When the PHS 31 receives the dynamic signal transmitted from the transmission unit 24 via the private branch exchange P and the antenna A, the PHS 31 sounds a ringing tone and, at the same time, dynamic information of the cared person based on the dynamic signal. Is displayed on the display unit 31a together with the identification numbers of the room and the bed. At this time, the displayed dynamic information may be text information such as “sleeping”, “long sitting”, “end sitting”, “standing”, “walking start”, etc., or may be previously associated with each dynamic. It may be a number or a symbol.
Also, a PHS 35 for transmission is installed in the transmission unit 24 on the side of the bed, and a dynamic signal transmitted from the PHS 35 is transmitted to an outdoor PHS 35.
The PHS 31 may receive the signal via an HS antenna (not shown).

The pager 32, like the PHS 31, converts the dynamic signal transmitted from the transmission unit 24 into a private branch exchange P,
When the signal is received via the antenna A, the ringing tone is sounded, and at the same time, the dynamic information of the cared person based on the dynamic signal is displayed on the display unit 32a together with the room and bed identification numbers.

The nurse call 33 is a device for notifying a nurse installed at a nurse station in a hospital or nursing home. The nurse call 33 has an indicator lamp, and an LED (Li) based on a dynamic signal transmitted from the transmission unit 24.
ght-Emitting Diode) 32a is turned on or off.
That is, for example, the LED 32a lights green when the transmitted dynamic signal is “sleeping posture”, yellow when “long sitting”, red when “end sitting”, and red when “standing”. Blinks, and in the case of "walking start", the red blinks quickly. Further, a configuration may be adopted in which each dynamic is notified according to the type of alarm sound such as a melody or a chime sounded by the speaker 32b.

The telemeter 34 includes a telemeter transmitting unit 34
a, a telemetry receiving unit composed of a telemeter receiving unit 34b and a printing unit 34c. The telemeter transmission unit 34a

The telemeter receiving section 34b can decode the dynamic signal and sequentially record the dynamic information of the cared person, and can also print the dynamic information as time-series data on a predetermined sheet by the printing section 34c.

Next, a specific processing example of the movement detection system 1 will be described with reference to FIGS. FIG. 3A is a perspective view illustrating a dynamic state detection operation when the care receiver takes a sleeping posture. As shown in FIG. 3A, when the cared person is in the sleeping position, all the sensors disposed in the bed 2 or in the vicinity thereof do not respond, and therefore the dynamic detection device 10 transmits a detection signal. do not do.

Next, FIG. 3B is a perspective view for explaining a dynamic detection operation when the care receiver is in a long sitting position. FIG.
As shown in (b), when the care receiver shifts to the long sitting position,
Two light beams L1, L projected by the upper optical sensors 11, 11
At least one of the two senses the care receiver. For this reason,
The upper optical sensor 11 transmits a detection signal to the transmission device 20. Further, after 5 seconds, when the transmission device 20 receives the detection signal from the upper optical sensor 11 again, the transmission device 20 receives the detection signal and transmits a “long sitting” dynamic signal to the output unit 30.

FIG. 4A is a perspective view for explaining the dynamic detection operation when the care receiver is at the end sitting position. As shown in FIG. 4A, when the care receiver shifts to the end sitting position, the light L1
The sensing of the human body by is canceled. At the same time, at least one of the two pressure-sensitive sheets 12, 12 senses the load of the care receiver, and the light beam L2 projected by the lower optical sensor 13 detects the care receiver. Therefore, the pressure-sensitive sheet 12 and the lower optical sensor 13 transmit a detection signal to the transmission device 20. Then, the transmission device 20 receives the two detection signals and transmits the two detection signals to the output unit 30 as a dynamic signal of “end sitting position”.

Next, FIG. 4B is a perspective view for explaining the dynamic detection operation when the care receiver is standing. FIG.
As shown in (b), when the care receiver shifts to the standing position, the sensing of the load by the pressure-sensitive sheet 12 is released. On the other hand, the light beam L2 projected from the lower optical sensor 13 continues to detect the care receiver. Therefore, the pressure-sensitive sheet 1
2 stops transmission of the detection signal to the transmission device 20. Then, the transmission device 20 detects the transmission stop of the detection signal,
The signal is transmitted to the output unit 30 as a dynamic signal of “standing”.

FIG. 5A is a perspective view for explaining a dynamic detection operation at the start of walking of the cared person. As shown in FIG. 5 (a), when the care receiver starts walking,
