  The fingerprint sensor 75 is a known fingerprint sensor, and is configured to be able to read a fingerprint using an optical sensor, for example (not shown in FIG. 2 described later). In addition, instead of the fingerprint sensor 75, for example, a means for recognizing a human physical feature such as a sensor for recognizing the shape of a palm vein (means capable of biometric authentication: identifying an individual) If it is a possible means), it can be adopted.

The relief request lever 77 will be described later (see FIG. 54).
Next, the shape of the aged pendant 1 will be described with reference to FIG. FIG. 2A is a perspective view showing a schematic shape of the pendant 1 for elderly people.

  As shown in FIG. 2 (a), the case 5 of the pendant 1 for elderly people has a substantially rectangular parallelepiped shape, and the GPS receiver 27 incorporated in the case 5 receives a signal from a GPS satellite. A GPS antenna 57 is disposed outside the housing 5. The elderly pendant 1 is designed assuming that the person to be monitored hangs the strap 7 connected to the mounting portion 7a provided on the upper surface 5c of the housing 5 around the neck of the person to be monitored, The GPS antenna 57 is disposed at a position that comes directly behind the neck when the monitoring subject puts the strap 7 on the neck.

  The strap 7 includes a signal line for guiding a signal received by the GPS antenna 57 into the housing 5. Further, an electrode portion 59 is formed in the vicinity of the GPS antenna 57 in the strap 7. That is, the signal line corresponding to the electrode portion 59 is also included in the strap 7 separately from the signal line of the GPS antenna 57.

  Here, the electrocardiographic sensor 33 can detect, for example, the operating state of the heart of the monitoring subject as an electrical signal by detecting a potential difference between the electrode unit 59 and a first conductive unit 83 described later. It is configured. Then, the MPU 51 of the rescue request signal transmission device 50 generates an electrocardiogram based on the detection signal from the electrocardiographic sensor 33.

  By the way, a display 61, a touch pad 71, and a confirmation button 73 are provided on the front surface 5a of the pendant 1 for elderly people. In addition, the temperature sensor 19, the humidity sensor 21, and the illuminance sensor 23 are also disposed on the front surface 5a (not shown).

A temperature sensor 15, a humidity sensor 17, and a wetness sensor 25 are disposed on the back surface 5 b of the elderly pendant 1.
And in addition to the above-mentioned attachment part 7a, the electrical decoration 63 and the speaker 65 are arrange | positioned at the upper surface of the pendant 1 for elderly people.

  Here, the wetting sensor 25 will be described with reference to FIGS. 2B and 2C. 2B is a rear view of the aged pendant 1, and FIG. 2C is a cross-sectional view of the aged pendant 1.

  As shown in FIGS. 2B and 2C, the wetness sensor 25 is formed on the back surface 5b of the housing 5. That is, the back surface 5 b of the housing 5 is configured as a conductive portion made of a conductor, and this conductive portion is formed between the first conductive portion 83 and the first conductive portion 83 formed in a ring shape via the groove portion 87. It is separated into a second conductive portion 85 surrounding the periphery in a ring shape. A preset potential difference is applied between the conductive portions 83 and 85. The groove portion 87 has a function of insulating the first conductive portion 83 and the second conductive portion 85.

  At this time, if the back surface 5b of the housing 5 is not in contact with the monitoring subject's skin, the conductive portions 83 and 35 are not electrically connected, but the back surface 5b of the housing 5 is not exposed to the monitoring subject's skin. When the person to be monitored is also sweating, electricity flows through the sweat, so that the conductive parts 83 and 85 are electrically connected.

That is, the wetness sensor 25 of the present embodiment detects sweating of the monitoring subject using the principle as described above.
Further, as shown in FIG. 2C, a concave portion 81 is formed inside the first conductive portion 83, and the temperature sensor 15, the humidity sensor 17, and the microphone 37 are formed on the bottom surface portion of the concave portion 81. Is arranged. The reason for this configuration is to prevent the temperature sensor 15, the humidity sensor 17, and the microphone 37 from directly touching the person being monitored. The microphone 37 is used to detect the voice or heart sound (heart sound) of the person being monitored.

  Moreover, it is comprised so that the audio | voice of a monitoring subject can be registered into RAM (non-volatile RAM: illustration not shown) of the relief request signal transmission apparatus 50, MPU51 of the relief request signal transmission apparatus 50 is comprised. It has a function of identifying the voice of the monitoring target person based on the registered voice characteristics (for example, voiceprint) of the monitoring target person. Further, a word is registered in the RAM, and the MPU 51 identifies a specific word (for example, “help” or “help”, etc.), scream, moan, etc., issued by the person to be monitored by referring to the RAM. Also have.

[Walking judgment processing]
The process for detecting that the monitoring subject is walking in the above-described elderly pendant 1 will be described with reference to FIG. FIG. 3 is a flowchart illustrating the walking determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This walking determination process is a process that is started periodically (for example, every 10 ms), and first, outputs (inputs) three directions from the three-dimensional acceleration sensor 11 (S10), and these three directions Are temporarily stored in a memory such as a RAM (S15). For example, the output for 3 seconds is stored in the memory.

  Subsequently, based on the outputs in the three directions stored in the memory, a plurality of acceleration peaks (absolute maximum and minimum values) in each direction are detected, and the peak-to-peak time in each direction is detected (S20: Peak-to-peak time detection means). And the peak period showing the average value of the detected time between peaks is calculated for every direction (S25: peak period calculation means).

  Next, of the calculated peak periods in each direction, whether or not at least the peak period in two directions or a double period of the peak period in the two directions is within a range of 10% (within the first set range), for example. (S30: walking determination means).

  When the peak period in at least two directions or the double period of the peak period in the two directions is within a range of 10% (S30: Yes), a signal such as RAM is stored as a signal indicating that the monitoring target is walking. Is stored (output) (S35), and the walking determination process is terminated. Further, if the peak period in two directions or the double period of the peak period in two directions is out of the range of 10% (S30: No), it is determined that the monitoring target is not always walking and an unknown signal during walking is stored in the RAM. Or the like (S40), and the walking determination process is terminated.

  According to the walking determination process executed by the old man's pendant 1, if the monitoring subject wears the old man's pendant 1, the periodic acceleration that the monitoring subject gives to the old man's pendant 1 during walking. Changes can be detected. Therefore, it can be determined that the monitoring subject is walking.

[Stop judgment processing]
Next, processing for detecting that the monitoring subject is stopped in the elderly pendant 1 will be described with reference to FIG. FIG. 4 is a flowchart showing a stop determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This stop determination process is a process that is started periodically (for example, every 10 ms). First, three-direction output from the three-dimensional acceleration sensor 11 is acquired (input) (S60), and these three directions Are temporarily stored in a memory such as a RAM (S65). For example, the output for 3 seconds is stored in the memory.

Subsequently, the acceleration peak in each direction is detected based on the outputs in the three directions stored in the memory (S70: peak value detecting means).
Next, it is determined whether or not all detected peak values in the three directions are equal to or less than the first stop determination value (first stop determination threshold) (S75: stop determination means). If all of the peak values in the three directions are equal to or less than the first stop determination value (S75: Yes), the stop signal is stored (output) in a memory such as a RAM (S80), assuming that the monitoring subject is stopped (S80). The stop determination process is terminated. If all the peak values are equal to or greater than the first stop determination value (S75: No), the stop target unknown signal is stored (output) in a memory such as a RAM, assuming that the person being monitored is not stopped ( S80), the stop determination process is terminated.

  According to the stop determination process executed by the old man's pendant 1, if the monitoring subject wears the old man's pendant 1, the change in the acceleration given to the old man's pendant 1 when the monitoring subject stops is detected. Since it is possible to detect that it is hardly felt, it is possible to determine whether or not the monitoring subject is stopped.

[Sitting motion judgment process]
Next, a process for detecting that the monitoring subject is sitting in the elderly pendant 1 will be described with reference to FIG. FIG. 5 is a flowchart showing a sitting motion determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This sitting motion determination process is a process that is started periodically (for example, every 10 ms). First, three-direction outputs from the three-dimensional acceleration sensor 11 are acquired (input) (S110), The direction output is temporarily stored in a memory such as a RAM (S115). For example, the output for 3 seconds is stored in the memory.

Subsequently, acceleration peaks in each direction are detected based on the outputs in the three directions stored in the memory (S120: peak value detecting means).
Next, the detected peak value in the downward direction in the vertical direction (−Z direction) is equal to or greater than the sitting motion determination value, and both the peak values in the horizontal direction (X direction and Y direction) are less than the second stop determination threshold value. It is determined whether or not there is present (S125: sitting motion determination means). If the peak value in the vertical downward direction is greater than or equal to the sitting movement determination value and both the peak values in the horizontal direction are less than the second stop determination threshold (S125: Yes), the person being monitored is sitting The sitting motion signal is stored (output) in a memory such as a RAM (S130), and the sitting motion determination process is terminated.

  If the peak value in the downward direction in the vertical direction is less than the sitting motion determination value, or if any of the peak values in the horizontal direction is equal to or greater than the second stop determination threshold value (S125: No), that the person being monitored is in the sitting motion The sitting motion unknown signal is stored (output) in a memory such as a RAM (S135), and the sitting motion determination process is terminated.

  According to the sitting movement determination process executed by the elderly person's pendant 1, if the person to be monitored wears the pendant 1 for the elderly person, when the person to be monitored is sitting, Since the acceleration can be detected and it can be detected that the acceleration in the other direction is hardly felt, it is possible to determine whether or not the monitoring subject is sitting.

[Rising motion judgment processing]
Next, in the pendant 1 for elderly people, a process for detecting that the monitoring target person is standing up will be described with reference to FIG. FIG. 6 is a flowchart showing a rising motion determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This rising motion determination process is a process that is started periodically (for example, every 10 ms). First, three-direction outputs from the three-dimensional acceleration sensor 11 are acquired (input) (S160). The direction output is temporarily stored in a memory such as a RAM (S165). For example, the output for 3 seconds is stored in the memory.

Subsequently, based on the outputs in the three directions stored in the memory, the peak of acceleration in each direction is detected (S170: peak value detecting means).
Next, the detected peak value in the upward direction in the vertical direction (+ Z direction) is equal to or greater than the rising motion determination value, and both the peak values in the horizontal direction (X direction and Y direction) are less than the third stop determination threshold value. (S175: rising motion determination means). If the peak value in the upward direction in the vertical direction is greater than or equal to the rising motion determination value and both of the peak values in the horizontal direction are less than the third stop determination threshold value (S175: Yes), the person being monitored is in the rising motion The rising operation signal is stored (output) in a memory such as a RAM (S180), and the rising operation determination process is terminated.

  If the peak value in the upward direction in the vertical direction is less than the rising motion determination value, or if any of the peak values in the horizontal direction is greater than or equal to the third stop determination threshold value (S175: No), the monitoring subject is in the rising motion state. The rising operation unknown signal is stored (output) in a memory such as a RAM (S185), and the rising operation determination process is terminated.

  According to the rising motion determination process executed by the elderly pendant 1, if the monitoring subject wears the elderly pendant 1, when the monitoring subject is performing the rising motion, the vertically upward movement is performed. Since the acceleration can be detected and it can be detected that the acceleration in the other direction is hardly felt, it is possible to determine whether or not the monitoring subject is standing up.

[Right turn motion judgment processing]
Next, a process for detecting that the monitoring subject is performing a right turn operation in the elderly pendant 1 will be described with reference to FIG. FIG. 7 is a flowchart showing a right turn motion determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This right turn motion determination process is a process that is started periodically (for example, every 10 ms). First, three-direction outputs from the three-axis gyro sensor 13 are acquired (input) (S210). The outputs in the three directions are temporarily stored in a memory such as a RAM (S215). For example, the output for 3 seconds is stored in the memory.

  Next, based on the output result stored in the memory, a positive direction (vertically upward in the vertical direction with the vertical direction within a preset angle determination time (for example, 2 seconds) as a rotation axis) Is detected (S220). Then, it is determined whether or not the rotation angle in the positive direction exceeds, for example, 30 degrees (angle setting threshold) (S225: forward turn operation determination means).

  If the rotation angle in the forward direction exceeds 30 degrees (S225: Yes), the right turn operation signal is stored (output) in a memory such as a RAM (S230), assuming that the monitoring subject is performing a right turn operation. Then, the right turn motion determination process is terminated. If the rotation angle in the positive direction does not exceed 30 degrees (S225: No)), a right turn operation unknown signal is output assuming that the monitoring target is not necessarily in the right turn operation (S235), End the right turn motion determination process.

According to such a right turn operation determination process executed by the old man's pendant 1, if the monitoring subject wears the old man's pendant 1, when the monitoring subject turns (rotates) in the forward direction, the vertical direction Because it is possible to detect the rotation angle in the positive direction with the rotation axis as the rotation axis, it is possible to determine whether or not the person to be monitored has turned in the forward direction [Left turn motion determination process]
Next, in the pendant 1 for elderly people, a process for detecting that the monitoring subject is performing a left turn operation will be described with reference to FIG. FIG. 8 is a flowchart showing a left turn operation determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This left-turn motion determination process is a process that is started periodically (for example, every 10 ms). First, three-direction outputs from the three-axis gyro sensor 13 are acquired (input) (S260). The outputs in the three directions are temporarily stored in a memory such as a RAM (S265). For example, the output for 3 seconds is stored in the memory.

  Next, based on the output result stored in the memory, the negative direction (vertical direction upward rotation to the right in the vertical direction within a preset angle determination time (for example, 2 seconds)), that is, for the monitoring subject. ) Is detected (S270). Then, it is determined whether or not the rotation angle in the negative direction exceeds, for example, 30 degrees (angle setting threshold) (S275: reverse turn operation determination means).

  If the rotation angle in the negative direction exceeds 30 degrees (S275: Yes), the left turn operation signal is stored (output) in a memory such as a RAM (S280), assuming that the person to be monitored is performing a left turn operation (S280). Then, the left turn motion determination process is terminated. Further, if the rotation angle in the negative direction does not exceed 30 degrees (S275: No)), the left turn operation unknown signal is output assuming that the monitoring target is not always in the right turn operation (S285), The left turn motion determination process is terminated.

According to such a left turn operation determination process executed by the old man's pendant 1, if the monitoring subject wears the old man's pendant 1, when the monitoring subject turns (rotates) in the reverse direction, the vertical direction Since the rotation angle in the negative direction with the rotation axis as the rotation axis can be detected, it is possible to determine whether or not the monitoring subject has turned in the reverse direction [Skin contact state determination processing]
Next, a process for detecting that the pendant 1 for elderly people is in contact with the background of the person to be monitored will be described with reference to FIG. FIG. 9 is a flowchart showing the background contact state determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This background contact state determination process is a process executed during the process of the background contact clothes outside state determination process (FIG. 10) and the background contact clothes inside state determination process (FIG. 11), which will be described later. The output from the temperature sensor 15, the output from the back humidity sensor 17, the output from the front temperature sensor 19, and the output from the front humidity sensor 21 are acquired (input) (S310 to S325).

  Then, it is determined whether or not the temperature detected by the temperature sensor 15 on the back surface is within a range of 30 to 40 degrees (within the background determination range) (S330: background temperature range determination means). If the temperature detected by the back surface temperature sensor 15 is within a range of 30 to 40 degrees (S330: Yes), the temperature difference between the temperatures detected by the back surface temperature sensor 15 and the front surface temperature sensor 19 is, for example, 2 It is determined whether it is more than degree (background temperature determination threshold) (S335: background temperature difference determination means).

  When it is determined that the temperature difference between the temperatures detected by the temperature sensors 15 and 19 is less than 2 degrees (S335: No), the humidity difference between the relative humidity detected by the humidity sensors 17 and 21 is 5 % (Background humidity determination threshold) or more is determined (S340: background humidity difference determining means).

  When it is determined that the temperature difference between the temperatures detected by the temperature sensors 15 and 19 is 2 degrees or more (S335: No), and the humidity difference between the relative humidity detected by the humidity sensors 17 and 21 is If the difference is 5% (background moisture determination threshold) or more (S340: Yes), the background contact state signal is stored in a memory such as a RAM, assuming that the aged pendant 1 is in contact with the user's background. (Output) (S345), and the background contact state determination process is terminated.

  On the other hand, when the temperature detected by the temperature sensor 15 on the back surface is outside the range of 30 to 40 degrees (S330: No), the humidity difference between the humidity detected by the humidity sensors 17 and 21 is less than 5%. In this case, it is assumed that the elderly pendant 1 is not necessarily in contact with the user's background, and a background contact state unknown signal is output (S350), and the background contact state determination process is terminated. In addition, the process of S330-S340 is corresponded to a background contact state judgment means.

  Thus, in the pendant 1 for elderly people in which the temperature sensors 15 and 19 and the humidity sensors 17 and 21 are arranged on the front surface 5a and the back surface of the casing, the back surface temperature sensor 15 and the back humidity sensor 17 are the background of the person being monitored. When it is in contact with the sensor, it is affected by body temperature and sweating, so the output from this temperature sensor and humidity sensor has a temperature difference and humidity difference of a certain level or more with respect to the output of the other temperature sensor and humidity sensor. Should occur. For this reason, in the pendant 1 for elderly people, the temperature difference and humidity difference more than a threshold value are detected based on the difference of the detection result by each temperature sensor and a humidity sensor.

  Further, in order to prevent erroneous detection when the back surface of the housing 5 is not in contact with the background of the person being monitored, temperature differences and humidity differences are detected by the temperature sensors 15 and 19 and the humidity sensors 17 and 21. Before, it is detected whether the temperature detected by the temperature sensor 15 on the back surface is close to the body temperature of the person being monitored.

Therefore, according to the background contact state determination process performed by such an aged pendant 1, it can be reliably detected that the aged pendant 1 is in contact with the user's background.
[Out-of-skin contact clothing state judgment processing]
Next, a process for detecting that the elderly pendant 1 is outside the clothing of the monitoring subject while in contact with the background of the monitoring subject will be described with reference to FIG. FIG. 10 is a flowchart showing the background contact clothing outside state determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background contact out-of-clothes state determination process is a process that is periodically activated (for example, every 10 ms). First, the above-described background contact state determination process (FIG. 9) is executed (S360). Then, referring to a memory such as a RAM, it is determined whether or not the background contact state is output in the background contact state determination process (S365).

If the background contact state is not output in the background contact state determination process (S365: No), this background contact out-of-clothes state determination process is terminated.
If the background contact state is output in the background contact state determination process (S365: Yes), the output of the front humidity sensor 21 is acquired (input) (S370), and the output of the front humidity sensor 21 is set to 1 minute. Each time it is temporarily stored in a memory such as a RAM (S375). For example, the output for 10 minutes is stored in the memory.

  Subsequently, for example, within 10 minutes (within the first humidity change determination time), the output from the front humidity sensor 21 stored in the memory indicates a change in humidity of, for example, 10% (first humidity change determination threshold) or more. It is determined whether or not it has been shown twice or more (S380: background contact clothing state determination means). If the output from the humidity sensor 21 shows a change in humidity of 10% or more twice or more (S380: Yes), it is assumed that the elderly pendant 1 is outside the clothing in contact with the background of the person being monitored. The contact out-of-clothes state signal is stored (output) in a memory such as a RAM (S385), and the ground contact out-of-clothes state determination process is terminated.

  In addition, if the output from the humidity sensor 21 indicates a change in humidity of 10% or more less than twice (S380: No), it is assumed that the pendant 1 for the elderly is not necessarily on the outside of the clothes, and the skin contact clothes outside state An unknown signal is output (S390), and the background contact clothing outside state determination process is terminated.

  That is, in the elderly pendant 1, when the elderly pendant 1 is outside the clothes, the change in humidity is larger than when the elderly pendant 1 is inside the clothes. Based on whether the detection result by the humidity sensor shows a change equal to or greater than the threshold value, the elderly pendant 1 is detected to be located outside the clothing of the person being monitored.

Therefore, it can be detected that the pendant 1 for the elderly is in contact with the background of the person being monitored and is located outside the clothes of the user.
[Skin contact clothes state judgment processing]
Next, a process for detecting that the elderly pendant 1 is outside the clothing of the monitoring subject while in contact with the background of the monitoring subject will be described with reference to FIG. FIG. 11 is a flowchart showing a background contact clothing state determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background contact state determination process is a process that is started periodically (for example, every 10 ms). First, the above-described background contact state determination process (FIG. 9) is executed (S410). Then, referring to a memory such as a RAM, it is determined whether or not the background contact state is output in the background contact state determination process (S415).

If the background contact state is not output in the background contact state determination process (S415: No), this background contact clothes state determination process is terminated.
If the background contact state is output in the background contact state determination process (S415: Yes), the output of the front humidity sensor 21 is acquired (input) (S420), and the output of the front humidity sensor 21 is set to 1 minute. Each time it is temporarily stored in a memory such as a RAM (S425). For example, the output for 10 minutes is stored in the memory.

  Subsequently, for example, within 10 minutes (within the second humidity change determination time), the output from the front humidity sensor 21 stored in the memory indicates a change in humidity of, for example, 10% (second humidity change determination threshold) or more. It is determined whether or not it has been shown twice or more (S430: background contact state determination means). If the output from the humidity sensor 21 indicates a change in humidity of 10% or more less than twice (S430: Yes), the elderly pendant 1 is assumed to be inside the clothing in contact with the background of the person being monitored. The background contact clothes state signal is stored (output) in a memory such as a RAM (S435), and the background contact clothes state determination process is terminated.

  In addition, if the output from the humidity sensor 21 shows a change in humidity of 10% or more twice or more (S430: No), it is not necessarily assumed that the elderly pendant 1 is inside the clothing. A signal is output (S440), and the background contact clothing state determination process is terminated.

  That is, the elderly pendant 1 detects that the elderly pendant 1 is located inside the clothing of the person to be monitored based on whether or not the detection result by the humidity sensor shows a change less than the threshold value.

  Therefore, according to the background contact in-clothing state determination process executed by such an elderly pendant 1, the positional relationship detection device is in contact with the background of the person being monitored and positioned inside the user's clothes. Can be detected.

[Non-contact state judgment processing]
Next, a process for detecting that the pendant 1 for elderly people is not in contact with the background of the monitoring subject will be described with reference to FIG. FIG. 12 is a flowchart showing the background non-contact state determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background contact state determination process is a process executed during the process of the background non-contact out-of-clothes state determination process (FIG. 13) and the background non-contact out-of-clothes state determination process (FIG. 14). The output from the temperature sensor 15 on the back surface, the output from the humidity sensor 17 on the back surface, the output from the temperature sensor 19 on the front surface, and the output from the humidity sensor 21 on the front surface are acquired (input) (S460 to S475).

  Then, it is determined whether or not the temperature detected by the temperature sensor 15 on the back surface is outside the range of 10 to 45 degrees (outside the first non-background determination range) (S480: first non-background temperature range determination means). If the temperature detected by the back surface temperature sensor 15 is within the range of 10 to 45 degrees (S480: No), the temperature difference between the temperatures detected by the back surface temperature sensor 15 and the front surface temperature sensor 19 is, for example, 1 It is determined whether it is less than the degree (non-background temperature determination threshold) (S485: non-background temperature difference determination means).

  If it is determined that the temperature difference between the temperatures detected by the temperature sensors 15 and 19 is less than 1 degree (S485: Yes), the output from the front temperature sensor 19 is outside the range of 35 to 38 degrees (first It is determined whether or not (outside 1 non-background determination range) (S490: first non-background temperature range determination means).

  When the temperature detected by the back surface temperature sensor 15 is outside the range of 10 to 45 degrees (S480: Yes), and when the output from the front surface temperature sensor 19 is outside the range of 35 to 38 degrees (S490: Yes) ), The background non-contact state signal is stored (output) in a memory such as a RAM, assuming that the elderly pendant 1 is not in contact with the background of the person being monitored (S495), and the background non-contact state determination processing is terminated. .

  When it is determined that the temperature difference between the temperatures detected by the temperature sensors 15 and 19 is 1 degree or more (S485: No), and the output from the front temperature sensor 19 is in the range of 35 to 38 degrees. If it is within the range (S490: No), the elderly person's pendant 1 is not necessarily in contact with the background of the person being monitored and outputs a background non-contact state unknown signal (S500), and the background non-contact state. The determination process ends. In addition, the process of S480-S490 is corresponded to a background non-contact state determination means.

  According to the background non-contact state determination process executed by the elderly pendant 1, the elderly pendant 1 comes into contact with the background of the person to be monitored based on the detection results of the temperature sensors 15 and 19 arranged in plurality. When the temperature that is not detected is detected, it is determined that the elderly pendant 1 is not in contact with the background of the person to be monitored. Therefore, it is detected that the elderly pendant 1 is not in contact with the background of the user. can do.

[Non-contact out-of-clothes condition determination process]
Next, a process for detecting that the elderly pendant 1 is outside the monitoring subject's clothes without being in contact with the monitoring subject's background will be described with reference to FIG. FIG. 13 is a flowchart showing the background non-contact out-of-clothes state determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background non-contact out-of-clothes state determination process is a process that is started periodically (for example, every 10 ms), and first, the above-described background non-contact state determination process (FIG. 12) is executed (S510). Then, referring to a memory such as a RAM, it is determined whether or not a background non-contact state is output in the background non-contact state determination process (S515).

If the background non-contact state is not output in the background non-contact state determination process (S515: No), the background non-contact out-of-clothes state determination process is terminated.
If the background non-contact state is output in the background non-contact state determination process (S515: Yes), the output of the illuminance sensor 23 is acquired (input) (S520), and the output of the illuminance sensor 23 is changed every minute. The data is temporarily stored in a memory such as a RAM (S525). For example, the output for 10 minutes is stored in the memory.

Subsequently, for example, within 10 minutes (within the first illuminance change determination time), the output from the illuminance sensor 23 stored in the memory, for example, changes the illuminance more than 10% (first illuminance change determination threshold) five times. It is determined whether or not the above has been shown (S530: non-contact-out-clothes state determination means). If the output from the illuminance sensor 23 shows a change in illuminance of 10% or more five times or more (S530: Yes), the elderly pendant 1 is outside the clothing in a state where it is not in contact with the background of the person being monitored. The background non-contact clothes outside state signal is stored (output) in a memory such as a RAM (S535), and the background non-contact clothes outside state determination process is terminated.

Further, if the output from the illuminance sensor 23 shows an illuminance change of 10% or more less than 5 times (S530: No), it is assumed that the elderly pendant 1 is not necessarily on the outside of the clothes, and the non-skin-free clothing. An outside state unknown signal is output (S540), and the background non-contact clothing outside state determination process is terminated.

  That is, in the elderly pendant 1, when the elderly pendant 1 is outside the clothes, the change in illuminance is larger than when the elderly pendant 1 is inside the clothes. Based on whether the detection result by the illuminance sensor shows a change equal to or greater than the threshold, it is detected that the elderly pendant 1 is located outside the clothing of the monitoring subject.

  Therefore, according to the background non-contact out-of-clothes state determination process executed by the elderly man's pendant 1, the elderly man's pendant 1 is not in contact with the subject's subject's background and is located outside the subject's clothing. Can be detected.

[Non-contact skin condition determination process]
Next, a process for detecting that the elderly pendant 1 is inside the monitoring subject's clothes without being in contact with the monitoring subject's background will be described with reference to FIG. FIG. 14 is a flowchart showing the background non-contact in-clothing state determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background non-contact clothing state determination process is a process that is started periodically (for example, every 10 ms). First, the above-described background non-contact state determination process (FIG. 12) is executed (S560). Then, referring to a memory such as a RAM, it is determined whether or not a background non-contact state is output in the background non-contact state determination process (S565).

If the background non-contact state is not output in the background non-contact state determination processing (S565: No), the background non-contact clothing outside state determination processing is terminated.
If the background non-contact state is output in the background non-contact state determination process (S565: Yes), the output of the illuminance sensor 23 is acquired (input) (S570), and the output of the illuminance sensor 23 is changed every minute. The data is temporarily stored in a memory such as a RAM (S575). For example, the output for 10 minutes is stored in the memory.

  Subsequently, for example, within 10 minutes (within the second illuminance change determination time), the output from the illuminance sensor 23 stored in the memory undergoes a change in illuminance that is, for example, 10% (second illuminance change determination threshold) or more twice. It is determined whether or not the above is shown (S580: background non-contact out-of-clothes state determination means). If the output from the illuminance sensor 23 shows an illuminance change of 10% or more less than twice (S580: No), the elderly pendant 1 is outside the clothing in a state where it is not in contact with the background of the person being monitored. The background non-contact clothes state signal is stored (output) in a memory such as a RAM (S585), and the background non-contact clothes state determination process is terminated.

  Further, if the output from the illuminance sensor 23 shows a change in illuminance of 10% or more twice or more (S580: Yes), the elderly pendant 1 is not necessarily on the inside of the clothes and is not in the ground contactless clothing. A state unknown signal is output (S590), and the background non-contact in-clothing state determination process is terminated.

  According to such a pendant 1 for the elderly, it is detected that the pendant 1 for the elderly is located inside the clothes of the person to be monitored based on whether or not the detection result by the illuminance sensor shows a change less than the threshold value. Yes.

  Therefore, according to the background non-contact in-clothing state determination process executed by the aged pendant 1, it is determined that the aged pendant 1 is not in contact with the background of the person being monitored and is located inside the user's clothes. Can be detected.

[Pendant position determination processing]
Next, processing for detecting the positional relationship between the elderly pendant 1 and the monitoring subject will be described with reference to FIG. FIG. 15 is a flowchart illustrating a pendant position determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  The pendant position determination process is a process executed during processes such as an over-hot state determination process (FIG. 17), which will be described later. When the process is started, the background contact out-of-clothes state determination process (FIG. 10), the background Contact clothing state determination processing (FIG. 11), background non-contact out-of-clothes state determination processing (FIG. 13), and background non-contact clothing state determination processing (FIG. 14) are sequentially executed (S610 to S625: specific position determination means). .

  Then, by referring to the signals stored in the memory by these processes, the positional relationship between the elderly pendant 1 and the monitoring subject is specified (S630: positional relationship specifying means), and the pendant position determination process is terminated.

  According to such a pendant position determination process executed by the elderly pendant 1, the positional relationship between the elderly pendant 1 and the monitoring subject (whether the elderly pendant 1 is in contact with the background of the monitoring subject, and Whether the elderly pendant 1 is inside or outside the clothes of the person to be monitored).

[Exercise load judgment processing]
Next, processing for detecting the magnitude of the exercise load performed by the monitoring subject will be described with reference to FIG. FIG. 16 is a flowchart showing an exercise load determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  The exercise load determination process is a process executed during a process such as an over-hot state determination process (FIG. 17), which will be described later. When the process is started, the walking determination process (FIG. 3) and the stop determination process (FIG. 4) and the rising motion determination process (FIG. 6) are executed in order (S660 to S670). The various signals stored in the memory (determination count storage means) in the walking determination process, the stop determination process, and the rising motion determination process are held for 10 minutes (load determination time) every second.

  Subsequently, it is determined whether or not the number of rising operation signals (the number of rising operation determinations) stored in the memory is 100 (strong load determination threshold) or more (S675: heavy load determination means). If the number of rising motion signals is 100 or more (S675: Yes), a strong load determination signal is stored (output) in a memory such as a RAM (S680), assuming that the monitoring subject has performed a heavy load exercise (S680). Then, based on the load determination signal stored in the memory, the magnitude of the exercise load of the exercise performed by the monitoring subject is specified (S720: exercise load specifying means), and the exercise load determination process ends.

  If the number of rising operation signals is less than 100 (S675: No), it is determined whether the number of rising operation signals is 50 or more (medium load determination threshold: strong load determination threshold> medium load determination threshold). (S685: Medium load determination means). If the number of rising motion signals is 50 or more (S685: Yes), a medium load determination signal is stored (output) in a memory such as a RAM (S690), assuming that the monitoring subject has performed a medium load exercise (S690). And the process of above-mentioned S720 is performed and an exercise | movement load judgment process is complete | finished.

  If the number of rising motion signals is less than 50 (S685: No), the number of walking signals is 300 (light load determination threshold: load magnitude (for example, calorie consumption), medium load determination threshold> light load It is determined whether it is equal to or greater than (determination threshold) (S695: light load determination means). If the number of signals during walking is 300 or more (S695: Yes), a light load determination signal is stored (output) in a memory such as a RAM (S700), assuming that the monitoring subject has performed a light load exercise. And the process of above-mentioned S720 is performed and an exercise | movement load judgment process is complete | finished.

  If the number of signals during walking is less than 300 (S695: No), it is determined whether the number of signals during stop (number of determinations during stop) is equal to or greater than 400 (stop determination threshold) (S705: No load judgment means). If the number of stopped signals is 400 or more (S705: Yes), a no-load determination signal is stored (output) in a memory such as a RAM (S710), assuming that the person to be monitored is not performing a load exercise (S710). And the process of above-mentioned S720 is performed and an exercise | movement load judgment process is complete | finished.

  If the number of stopping signals is less than 400 (S705: No), the load determination unknown signal is stored (output) in a memory such as a RAM (S710), assuming that the magnitude of the load is unknown. And the process of above-mentioned S720 is performed and an exercise | movement load judgment process is complete | finished.

  According to such exercise load determination processing executed by the aged pendant 1, the type of exercise performed by the monitoring target person is detected, and the magnitude of the load is classified according to the number of times the exercise has been detected. Therefore, the magnitude of the exercise load of the exercise performed by the monitoring subject can be specified.

It should be noted that in order of increasing exercise load, the load is heavy load, medium load, light load, and no load.
[Overheat condition judgment processing]

  Subsequently, the overheat warning signal stored in the memory such as RAM is read (input) by S770 (S775), and if the overheat warning signal is stored in the memory (that is, the environment around the person to be monitored). Is determined to be too hot for the monitoring target person), the monitoring target person is notified that it is too hot (S780, S785: too hot notification means).

  Specifically, a message sound indicating that the temperature is too hot is output from the speaker 65 (S780), the illumination 63 is lit red, and a message indicating that the temperature is too hot is displayed on the display 61.

  According to the over-hot state determination process executed by the elderly pendant 1, when it is determined that the monitoring target person is too hot, the monitoring target person can be notified that the monitoring target person is too hot.

[Non-contact out-of-skin condition / no load treatment]
Next, the background non-contact out-of-clothes state / no load process will be described with reference to FIG. FIG. 18 is a flowchart showing the background non-contact out-of-clothes state / no load process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background non-contact out-of-clothes state / no load process is a process executed during the above-described over-hot state determination process (FIG. 17). First, the output of the front temperature sensor 19 and the front humidity sensor 21 are processed. Is acquired (input) (S810, S815).

Then, a temperature / humidity index DI (so-called discomfort index) is calculated (S820). Here, the calculation of the temperature and humidity index DI is obtained by substituting the temperature and humidity into a well-known arithmetic expression. As this arithmetic expression, for example, the following mathematical expression is used.
DI = 0.81T + 0.01H (0.99T-14.3) +46.3
However, T: Air temperature (Celsius temperature), H: Relative humidity (%).

  Many ordinary people feel comfortable when the temperature / humidity index DI is 70 to 75, when the temperature / humidity index DI exceeds 75, the heat feels somewhat uncomfortable, and when the temperature / humidity index DI exceeds 80, The heat feels uncomfortable, and when the temperature / humidity index DI exceeds 85, the heat feels extremely uncomfortable.

  However, depending on the magnitude of the exercise load performed by the person being monitored, even if the temperature and humidity index DI feels comfortable when not exercising, it may be uncomfortable when exercising vigorously. Therefore, in this embodiment, a temperature / humidity index DI (discomfort threshold) that the monitoring subject feels too hot is set according to the exercise load.

  That is, in S770, the process to be executed is selected according to the detection results of the pendant position determination process (FIG. 15) and the exercise load determination process (FIG. 16), but the discomfort threshold is set to a different value depending on the process. Therefore, it can be said that the discomfort threshold is selected according to the exercise load. In the present embodiment, the discomfort threshold is selected according to the exercise load. However, in consideration of the influence of the positional relationship between the elderly pendant 1 and the monitoring subject on the measurement of the temperature / humidity index DI, You may make it set a discomfort threshold according to a positional relationship.

Subsequently, it is determined whether or not the temperature / humidity index DI is 85 (discomfort threshold) or more (S825: discomfort threshold determination means).
If the temperature / humidity index DI is 85 or more (S825: Yes), an over-hot attention state signal is stored (output) in a memory such as a RAM, because the environment around the monitoring target is too hot for the monitoring target. (S830: Too hot determining means). On the other hand, if the temperature / humidity index DI is less than 85 (S825: No), an over-hot attention state unknown signal is output assuming that the environment around the monitoring subject is not always too hot for the monitoring subject (S835: Too hot judgment).

  According to the background non-contact out-of-clothes state / no load process executed by the pendant 1 for elderly people, the discomfort index is calculated, the discomfort index, the detection result by the positional relationship detection means, and the detection result by the exercise load detection means. It is detected that the state is too hot by comparing with a discomfort threshold set in accordance with. In particular, in this process, an unpleasant threshold (DI = 85) is set that makes the heat extremely unpleasant for people who are not exercising.

Therefore, it can be satisfactorily determined whether or not it is too hot according to the exercise load performed by the monitoring subject.
[Non-contact out-of-skin condition / light load treatment]
Next, the non-skin-out-clothes state / light load process will be described with reference to FIG. FIG. 19 is a flowchart showing the background non-contact out-of-clothes state / light load process executed by the MPU 51 of the rescue request signal transmission device 50.

First, the output of the front temperature sensor 19 and the front humidity sensor 21 are processed. Is acquired (input) (S860, S865).

Then, the temperature and humidity index DI is calculated (S870). Here, the calculation of the temperature / humidity index DI is performed by the same method as the above-described non-skin-out-of-skin condition / no load process (FIG. 18).
Subsequently, it is determined whether or not the temperature / humidity index DI is 80 (discomfort threshold) or more (S875: discomfort threshold determination means).

  If the temperature / humidity index DI is 80 or more (S875: Yes), an over-hot attention state signal is stored (output) in a memory such as a RAM because the surrounding environment of the monitoring target is too hot for the monitoring target. (S880: Too hot determining means). If the temperature / humidity index DI is less than 80 (S875: No), an over-hot attention state unknown signal is output assuming that the environment around the monitoring target is not always too hot for the monitoring target (S885: Too hot judgment).

  According to the background non-contact out-of-clothing / light load process executed by the pendant 1 for elderly people, the discomfort index is calculated, the detection result by the positional relationship detection means, and the detection result by the exercise load detection means. It is detected that the state is too hot by comparing with a discomfort threshold set in accordance with. In particular, in this process, the uncomfortable threshold (DI = 80) is such that the heat feels uncomfortable for those who are not exercising, but the heat feels very uncomfortable for those who are lightly exercising. Is set.

Therefore, it can be satisfactorily determined whether or not it is too hot according to the exercise load performed by the monitoring subject.
[Non-contacting out-of-ground condition / medium load treatment]
Next, the background non-contact out-of-clothes state / medium load process will be described with reference to FIG. FIG. 20 is a flowchart showing the background non-contact out-of-clothes state / medium load process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background non-contact out-of-skin condition / medium load process is a process executed during the process of the above-described over-hot condition determination process (FIG. 17). First, the output of the front temperature sensor 19 and the front humidity sensor 21 are processed. Is acquired (input) (S910, S915).

Then, the temperature / humidity index DI is calculated (S920). Here, the calculation of the temperature / humidity index DI is performed by the same method as the above-described non-skin-out-of-skin condition / no load process (FIG. 18).
Subsequently, it is determined whether or not the temperature / humidity index DI is 75 (discomfort threshold) or more (S925: discomfort threshold determination means).

  If the temperature / humidity index DI is 75 or more (S925: Yes), an over-hot attention state signal is stored (output) in a memory such as a RAM because the surrounding environment of the monitoring target is too hot for the monitoring target. (S930: too hot judgment means). On the other hand, if the temperature / humidity index DI is less than 75 (S925: No), an excessively hot caution state unknown signal is output assuming that the environment around the monitoring subject is not always too hot for the monitoring subject (S935: Too hot judgment).

  According to the background non-contact out-of-clothes / medium load process executed by the elderly pendant 1, the discomfort index is calculated, the discomfort index, the detection result by the positional relationship detection means, and the detection result by the exercise load detection means. It is detected that the state is too hot by comparing with a discomfort threshold set in accordance with. In particular, in this process, the heat level is slightly uncomfortable for those who are not exercising, but the unpleasant threshold value (DI = 75) where the heat level is extremely uncomfortable for those who are doing moderately exercising. ) Is set.

Therefore, it can be satisfactorily determined whether or not it is too hot according to the exercise load performed by the monitoring subject.
[Non-contact out-of-skin condition / heavy load treatment]
Next, the non-texture out-of-clothes state / heavy load process will be described with reference to FIG. FIG. 21 is a flowchart showing the background non-contact out-of-clothes state / heavy load process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background non-contact out-of-clothes state / heavy load process is a process executed during the process of the above-described over-hot condition determination process (FIG. 17). First, the output of the front temperature sensor 19 and the front humidity sensor 21 are processed. Is acquired (input) (S960, S965).

Then, the temperature / humidity index DI is calculated (S970). Here, the calculation of the temperature / humidity index DI is performed by the same method as the above-described non-skin-out-of-skin condition / no load process (FIG. 18).
Subsequently, it is determined whether or not the temperature / humidity index DI is 70 (discomfort threshold) or more (S975: discomfort threshold determination means).

  If the temperature / humidity index DI is 70 or more (S975: Yes), an over-hot attention state signal is stored (output) in a memory such as a RAM because the surrounding environment of the monitoring target is too hot for the monitoring target. (S980: too hot judgment means). If the temperature / humidity index DI is less than 70 (S975: No), an over-hot attention state unknown signal is output assuming that the environment around the monitoring target is not always too hot for the monitoring target (S985: Too hot judgment).

  According to the background non-contact out-of-clothing state / heavy load process executed by the pendant 1 for elderly people, the discomfort index is calculated, the detection result by the positional relationship detection means, and the detection result by the exercise load detection means. It is detected that the state is too hot by comparing with a discomfort threshold set in accordance with. In particular, in the present process, a discomfort threshold (DI = 70) is set in which a person who does not exercise feels comfortable, but a person who performs medium-load exercise feels heat is extremely uncomfortable.

Therefore, it can be satisfactorily determined whether or not it is too hot according to the exercise load performed by the monitoring subject.
[Non-contact in-skin condition / no load treatment]
Next, the background non-contact clothes state / no load processing will be described with reference to FIG. FIG. 22 is a flowchart showing the background non-contact in-clothes state / no load process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background non-contact clothes state / no load process is a process executed during the above-described over-hot condition determination process (FIG. 17), and basically the above-mentioned background non-contact clothes state / no load. This is the same processing as the processing (FIG. 18). However, since this processing is executed when it is detected that the elderly pendant 1 is inside the clothing of the monitoring subject, correction processing for eliminating the influence of the body temperature of the monitoring subject (S1010) ) Is executed between the process of S815 and the process of S820.

  In this correction process, first, in order to determine whether or not the output of the front temperature sensor 19 is affected by the body temperature of the person being monitored, whether or not the output of the front temperature sensor 19 is 36 degrees or more. Is determined (S1015). If the output of the front temperature sensor 19 is equal to or greater than 36 degrees (S1015: Yes), correction for decreasing the output of the front temperature sensor 19 as being affected by body temperature (for example, processing for multiplying the output by 0.9) ) Is executed (S1020: decrease correction means). Then, the correction process is terminated, and the process proceeds to S820.

  If the output of the front temperature sensor 19 is less than 36 degrees (S1015: No), it is determined that the output is not affected by body temperature, the correction process is terminated without correcting the output, and the process proceeds to S820.

  According to the background non-contact in-clothing state / no load process executed by the pendant 1 for elderly people, even if the output of the front temperature sensor 19 becomes a large value due to the body temperature of the monitoring subject, the monitoring subject The effect of body temperature can be eliminated.

[Non-contact clothes and light load treatment]
Next, the background non-contact clothes state / light load processing will be described with reference to FIG. FIG. 23 is a flowchart showing the background non-contact in-clothing state / light load process executed by the MPU 51 of the rescue request signal transmission device 50.

  The background non-contact clothes state / light load process is a process executed during the process of the above-mentioned over-hot condition determination process (FIG. 17). This is the same processing as the processing (FIG. 19). However, since this processing is executed when it is detected that the elderly pendant 1 is inside the clothing of the monitoring subject, correction processing for eliminating the influence of the body temperature of the monitoring subject (S1010) ) Is executed between the process of S865 and the process of S870.

The correction process in this process is the same process as the correction process in the above-described background non-contact in-clothing state / no load process (FIG. 22).
Therefore, according to the background non-contact in-clothing state / light load process performed by the pendant 1 for elderly people, even if the output of the temperature sensor 19 on the front side becomes a large value due to the body temperature of the person being monitored, The influence of the subject's body temperature can be eliminated.

  The background non-contact clothes state / medium load process is a process executed during the process of the above-mentioned over-hot condition determination process (FIG. 17), and basically the above-described background non-contact clothes state / medium load. This is the same processing as the processing (FIG. 20). However, since this process is executed when it is detected that the elderly pendant 1 is inside the clothes of the monitoring subject, the correction process for eliminating the influence of sweating by the monitoring subject (S1030). : Decrease correction means) is executed between the process of S915 and the process of S920.

  The correction process in this process is different from the correction process in the above-described background non-contact in-clothing state / no load process (FIG. 22). Process).

  That is, in S1220, the background non-contact out-of-clothing state signal or the out-of-ground contact out-of-clothing state signal is output in the pendant position determination processing (FIG. 15), and the no-load determination signal or in the exercise load determination processing (FIG. 16). If the light load determination signal is output, the after-clothing state / no load / light load process (FIG. 35) described later is executed.

  In S1220, a non-skin contact out-of-skin condition signal or a non-skin contact condition signal is output in the pendant position determination process (FIG. 15), and the medium load determination signal or If the heavy load determination signal is output, the out-of-clothes / medium load / heavy load process (FIG. 36) described later is executed.

  In S1220, the non-contact-in-clothing state signal or the ground-contact-in-clothing state signal is output in the pendant position determination process (FIG. 15), and no load determination signal or in the exercise load determination process (FIG. 16). If the light load determination signal is output, the in-clothes state / no load / light load process (FIG. 37) described later is executed.

  According to such an overly cold state determination process executed by the aged pendant 1, when it is determined that the monitoring subject is too cold, the monitoring subject can be notified that the monitoring subject is too cold.

[Out-of-clothes state, no load, light load processing]
Next, the out-of-clothes state / no load / light load process will be described with reference to FIG. FIG. 35 is a flowchart showing an out-of-clothes state / no load / light load process executed by the MPU 51 of the rescue request signal transmission device 50.

  The out-of-clothes state / no load / light load process is a process executed during the process of the above-described too cold state determination process (FIG. 34), and first obtains (inputs) the output of the front temperature sensor 19. (S1260).

  And it is determined whether the detection result by the temperature sensor 19 of the front is less than 0 degree (1st low temperature threshold value), for example (S1265: 1st low temperature threshold value determination means). If the detection result by the front temperature sensor 19 is 0 degree or more (S1265: No), the detection result by the front temperature sensor 19 is set to be 10 degrees (second low temperature threshold: first low temperature threshold). ) Is determined (S1270: second low temperature threshold determination means).

  If the detection result by the front temperature sensor 19 is less than 10 degrees (S1270: Yes), the output of the wind speed sensor 29 is acquired (input) (S1275), and the output of the wind speed sensor 29 is 5 m (wind speed threshold) or more. It is determined whether or not there is (S1280: wind speed determination means).

  When the detection result by the front temperature sensor 19 is less than 0 degree (S1265: Yes), when the output of the wind speed sensor 29 is 5 m or more (S1280: Yes), the environment around the person to be monitored is monitored. A too cold attention state signal is stored (output) in a memory such as a RAM as being too cold for the subject (S1285: too cold determination means), and the out-of-clothes state / no load / light load process ends.

  Further, when the detection result by the front temperature sensor 19 is 10 degrees or more (S1270: No), when the output of the wind speed sensor 29 is 5 m or more (S1280: No), the surrounding environment of the person to be monitored Is too cold for the person being monitored, a too cold attention state unknown signal is stored (output) in a memory such as a RAM (S1290: too cold judgment means), and the out-of-clothes state / no load / light load End the process.

  According to the out-of-clothes state / no load / light load process executed by the pendant 1 for elderly people, when the temperature detected by the temperature sensor 19 on the front surface is lower than the first low temperature threshold, it is necessary for the person to be monitored. It is determined that the temperature is too cold, and even if the temperature detected by the front temperature sensor 19 is higher than the first low temperature threshold, the temperature is lower than the second low temperature threshold and is higher than the wind speed threshold by the wind speed sensor 23. When the wind speed is detected, it is determined that the monitoring subject is too cold.

Therefore, according to such a portable monitoring device, it is possible to satisfactorily detect that it is too cold for the person being monitored because it uses the characteristic that the sensible temperature decreases as the wind speed increases.
[Out-of-clothes / medium load / heavy load processing]
Next, the out-of-clothes state / medium load / heavy load process will be described with reference to FIG. FIG. 36 is a flowchart showing an out-of-clothes / medium load / heavy load process executed by the MPU 51 of the rescue request signal transmitting apparatus 50.

  The out-of-clothes state / medium load / heavy load process is a process executed during the process of the above-described too cold state determination process (FIG. 34), and first obtains (inputs) the output of the front temperature sensor 19. (S1310).

  And it is determined whether the detection result by the temperature sensor 19 of the front is less than -5 degree (1st low temperature threshold value), for example (S1315: 1st low temperature threshold value determination means). If the detection result by the front temperature sensor 19 is −5 degrees or more (S1315: No), the detection result by the front temperature sensor 19 is set to be 5 degrees (second low temperature threshold: first low temperature threshold). .) Is determined (S1320: second low temperature threshold determination means).

  If the detection result by the front temperature sensor 19 is less than 5 degrees (S1320: Yes), the output of the wind speed sensor 29 is acquired (input) (S1325), and the output of the wind speed sensor 29 is 5 m (wind speed threshold) or more. It is determined whether or not there is (S1330: wind speed determination means).

  When the detection result by the front temperature sensor 19 is less than −5 degrees (S1315: Yes), when the output of the wind speed sensor 29 is 5 m or more (S1330: Yes), the environment around the person to be monitored is A too cold attention state signal is stored (output) in a memory such as a RAM as being too cold for the monitoring subject (S1335: too cold determination means), and the out-of-clothes state / medium load / heavy load process is terminated.

  When the detection result by the front temperature sensor 19 is 5 degrees or more (S1320: No), when the output of the wind speed sensor 29 is 5 m or more (S1330: No), the surrounding environment of the person to be monitored Is too cold for the person being monitored, a too cold attention state unknown signal is stored (output) in a memory such as a RAM (S1340: too cold judging means), and the out-of-clothes state / medium load / heavy load The process ends.

  According to such an out-of-clothes / medium load / heavy load process executed by the aged pendant 1, when the temperature detected by the front temperature sensor 19 is less than the first low temperature threshold, It is determined that the temperature is too cold, and even if the temperature detected by the front temperature sensor 19 is higher than the first low temperature threshold, the temperature is lower than the second low temperature threshold and is higher than the wind speed threshold by the wind speed sensor 23. When the wind speed is detected, it is determined that the monitoring subject is too cold.

Therefore, according to such a portable monitoring device, it is possible to satisfactorily detect that it is too cold for the person being monitored because it uses the characteristic that the sensible temperature decreases as the wind speed increases.
Note that the first low temperature threshold and the second low temperature threshold in this process are set to values smaller than the first low temperature threshold and the second low temperature threshold in the above-described out-of-clothes state / no load / light load process (FIG. 35), respectively. ing. The reason for this setting is that when the monitored person is engaged in strenuous exercise (medium-load exercise and heavy-load exercise), the monitored person is hardly exercising (no load or light load). This is because it is harder to feel cold than during exercise. Therefore, according to the pendant 1 for elderly people, it can detect well that it is too cold according to the magnitude | size of the exercise load which the monitoring subject performs.

If the difference between the output of the back temperature sensor 15 and the output of the front temperature sensor 19 is less than 3 degrees (S1370: No), is the output of the front temperature sensor 19 less than 5 degrees (fifth low temperature threshold)? (S1375: fifth low-temperature threshold determination means)
If the difference between the output of the back surface temperature sensor 15 and the output of the front surface temperature sensor 19 is 3 degrees or more (S1370: Yes), is the output of the back surface temperature sensor 19 less than 20 degrees (fourth low temperature threshold)? (S1380: 4th low temperature threshold value determination means).

  When the output of the front temperature sensor 19 is less than 5 degrees (S1375: Yes) and when the output of the back temperature sensor 19 is less than 20 degrees (S1380: Yes), the environment around the person being monitored However, an excessively cold attention state signal is stored (output) in a memory such as a RAM (S1385: too cold determination means), and the in-clothes state / no load / light load process is terminated.

  When the output of the front temperature sensor 19 is 5 degrees or more (S1375: No), and when the output of the back temperature sensor 19 is 20 degrees or more (S1380: No), the surrounding environment of the monitoring subject Is too cold for the person being monitored, a too cold attention state unknown signal is stored (output) in a memory such as a RAM (S1390: too cold judgment means), and the in-clothes state / no load / light load End the process.

Then, it is determined whether or not the difference between the output of the temperature sensor 15 on the back surface and the output of the temperature sensor 19 on the front surface is 3 degrees (third low temperature threshold value) or more (S1420: third low temperature threshold value determining means). If the difference between the output of the back temperature sensor 15 and the output of the front temperature sensor 19 is less than 3 degrees (S1420: No), is the output of the front temperature sensor 19 less than 0 degrees (fifth low temperature threshold)?

  When the output of the front temperature sensor 19 is less than 0 degrees (S1425: Yes) and when the output of the back temperature sensor 19 is less than 15 degrees (S1430: Yes), the environment around the monitoring target person However, an excessively cold attention state signal is stored (output) in a memory such as a RAM (S1435: too cold determination means), and the in-clothes / medium load / heavy load process is terminated.

  When the output of the front temperature sensor 19 is 0 degree or more (S1425: No) and when the output of the back temperature sensor 19 is 15 degrees or more (S1430: No), the surrounding environment of the monitoring subject Is too cold for the person being monitored, a too cold attention state unknown signal is stored (output) in a memory such as a RAM (S1440: too cold judging means), and the in-clothes state / medium load / heavy load End the process.

  According to the in-clothes state / medium load / heavy load process executed by the pendant 1 for elderly people, it is too cold for the monitoring target person as in the out-of-clothes state / medium load / heavy load process (FIG. 36). It can be detected well.

[Cold / warm relief request processing]
Next, a process for determining whether or not the monitoring subject needs to be rescued in the elderly pendant 1 will be described with reference to FIG. FIG. 39 is a flowchart showing the cold / warm rescue request process executed by the MPU 51 of the rescue request signal transmitter 50.

  This cold / warm relief request process is a process that is started periodically (for example, every 10 ms), and first, it is determined whether or not the relief request is being suspended (S1460: operation prohibiting means). Whether the relief request is being suspended is determined based on whether a later-described relief request suspension signal is stored in a memory such as a RAM.

If it is during the postponement of the relief request (S1460: Yes), the cold / warm relief request process is terminated.
If the relief request is not being suspended (S1460: No), the excessively cold warning signal and the excessively hot warning signal stored in the memory are acquired (input) (S1465, S1470).

  Then, it is determined whether or not an over-hot caution signal or an over-cold caution signal has been acquired (S1475). If an over-hot caution signal or an over-cold caution signal has not been acquired (S1475: No), the cold / warm rescue request process is terminated. If an over-hot caution signal or a too cold caution signal is acquired (S1475: Yes), the monitoring subject is notified that it is too hot or too cold (S 1480). Specifically, for example, a warning message sound indicating that the temperature is too hot or too cold is output from the speaker 65 so that the illumination 63 emits red light, and a message indicating the warning is displayed on the display 61.

  Then, the timer is started (S1485), the operation of the confirmation button 73 is accepted (S1490), and it is determined whether or not the confirmation button 73 has been operated (S1495: operation determination means). If the confirmation button 73 is not operated (S1495: No), it is determined whether or not 1 minute (standby time) has elapsed since the timer started (S1500: first rescue determination means).

  If one minute has not elapsed since the timer started (S1500: No), the process returns to S1490, and if one minute has elapsed since the timer started (S1500: Yes), the person to be monitored is selected. A relief request state signal is stored (output) in a memory such as a RAM as a need for relief (S1505), and the cold / warm relief request process is terminated.

  If the confirmation button 73 is operated (S1495: Yes), a relief request postponement signal for 30 minutes is stored (output) in a memory such as a RAM (S1510), and the cold / warm relief request processing is terminated.

  According to the cold / warm relief request process executed by the elderly pendant 1, monitoring is performed based on whether or not the confirmation button 73 is operated when it is detected that the monitoring subject is too hot or too cold. It is determined whether or not an abnormality such as a consciousness disorder or a movement disorder has occurred in the subject. Therefore, when the confirmation button 73 is not operated, such as when the monitoring target person cannot operate the operation unit, it is determined that the monitoring target person needs to be rescued as an abnormality has occurred in the monitoring target person. Can do. Moreover, since the judgment which rescues a monitoring subject can be prohibited for a fixed time until the grace time passes after the confirmation button 73 is operated, it is rescued when there is no abnormality in the monitoring subject. It is possible to prevent the necessity of being determined.

[Responsibility request setting process]
Next, in the pendant 1 for the elderly, a process for canceling the setting during the relief request will be described with reference to FIG. FIG. 40 is a flowchart illustrating a relief request grace setting process executed by the MPU 51 of the rescue request signal transmission device 50.

  This relief request grace setting process is a process activated periodically (for example, every 10 ms), and first obtains (inputs) a relief request grace signal stored in the memory (S1520). And it is determined whether the relief request postponement signal was acquired (S1525).

  If the relief request postponement signal is not acquired (S1525: No), the postponement setting process for the rescue request is ended. Moreover, if the relief request postponement signal is acquired (S1525: Yes), it will start after clearing a timer (S1530), and it will be determined whether 30 minutes passed since the timer started (S1535).

  If 30 minutes have not elapsed since the timer started (S1535: No), the processing of S1535 is repeated, and if 30 minutes have elapsed since the timer started (S1535: Yes), a memory such as a RAM The relief request postponement state is canceled by deleting the relief request postponement signal stored in (S1540), and the relief request postponement setting process is terminated.

  According to such a setting process during the grace period of the relief request executed by the pendant 1 for the elderly, when the fixed time (30 minutes in this case) has elapsed, the judgment grace state of the relief request can be canceled satisfactorily.

[Relief request transmission process]
Next, processing for transmitting a relief request in the elderly pendant 1 will be described with reference to FIG. FIG. 41 is a flowchart showing a rescue request transmission process executed by the MPU 51 of the rescue request signal transmission device 50.

  This relief request transmission process is a process activated periodically (for example, every 10 ms), and first obtains (inputs) a relief request state signal stored in the memory (S1560). And it is determined whether the relief request status signal was acquired (S1565).

If the rescue request state signal has not been acquired (S1565: No), the transmission process of the rescue request is terminated.
If a rescue request status signal has been acquired (S1565: Yes), information on the current location of the pendant 1 for the elderly detected by the GPS receiver 27 is input (S1570), and a rescue request email including this current location information is generated. Then, this mail is transmitted to a preset contact (S1575). When this process ends, the rescue request transmission process ends.

According to such a relief request transmission process executed by the aged pendant 1, when it is necessary to transmit a relief request, the relief request can be satisfactorily transmitted to the contact.
[徘徊 Judgment processing]
Next, processing for detecting that the monitoring subject is hesitant in the aged pendant 1 will be described with reference to FIG. FIG. 42 is a flowchart showing the wrinkle determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This habit determination process is a process that is started periodically (for example, every 10 ms). First, information on the current location of the pendant 1 for the elderly detected by the GPS receiver 27 is input (S1610), and a visit is made. The position information of the turn-around destination stored in the destination memory 55 is read (S1615).

  Then, it is determined whether or not the current location of the aged pendant 1 is a position other than the position registered as a turnaround destination (S1620). If the current location of the pendant 1 for the elderly is a position registered as a turnaround destination (S1620: No), the wrinkle determination process ends.

  If the current location of the pendant 1 for the elderly is not a position registered as a turnaround destination (S1620: Yes), a random short-term repeated determination process for walking / stop described later (S1625: FIG. 43), a walking / left described later. The right turn random short-term repetition determination process (S1630: FIG. 44) and the walking / sitting movement random short-term repetition determination process (S1635: FIG. 45) described later are sequentially executed. In other words, in the processing of S1625 to S1635, it is determined whether or not the monitoring target person is in a state of losing heart by determining whether or not the action of the monitoring target person is a specific pattern specific to the person performing the trap. Do (god god loss judgment means).

  Subsequently, it is determined whether or not a possibility signal for the loss of spirituality has been output in the processing of S1625 to S1635 (S1640). If the possibility signal of the loss of god is output (S1640: Yes), a rescue request state signal is output as a need to rescue the monitoring target person (S1645: first rescue judgment means), and a spear judgment process is performed. finish.

Moreover, if the possibility signal of the loss of god is not output (S1640: No), the wrinkle determination process is terminated.
According to the wrinkle determination process performed by such an old man's pendant 1, there is a possibility that the person to be monitored is hesitant when the information indicating the current location does not match the position information stored in the visited memory 55. As an object, it is determined whether or not the operation of the monitoring subject is a specific pattern. If it is detected that the action of the monitoring subject is a specific pattern, it is determined that the monitoring subject needs to be relieved as being in a state of loss of godliness.

Therefore, according to such a portable monitoring device, it is possible to detect that the monitoring subject is hesitant.
[Random, short and repeated judgment process for walking and stopping]
Next, walk / stop random short-term repetition determination processing will be described with reference to FIG. FIG. 43 is a flowchart illustrating a walk / stop random short-term repetition determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  The walking / stop random short-term repetition determination process is a process executed during the above-described wrinkle determination process (FIG. 42). First, the walking signal and the stopping signal stored in the memory are acquired ( (S1660.S1665).

  Then, a change from the signal during walking to the signal during stop is extracted (S1670), and it is determined whether or not a change from the signal during walking to the signal during stop is detected (S1675). If the change from the signal during walking to the signal during stoppage is not detected (S1675: No), the walking / stop random short-term repetition determination process is terminated.

  Moreover, if the change from the signal during a walk to the signal during a stop is detected (S1675: Yes), the number of times of change from the signal during a walk for 1 minute (within the first loss of gods determination time) to the signal during a stop is stored in RAM, (S1680). Then, it is determined whether or not the number of changes per minute is equal to or greater than 3 times (first mind loss threshold) (S1865: mind loss determination means).

  If the number of changes from the signal during walking to the signal during stop in less than one minute is less than 3 (S1585: No), the random short-term repeat determination process for walking / stop is terminated. Also, if the number of changes from a walking signal to a stop signal in one minute is three or more (S1585: Yes), the monitoring target person may be in a state of losing god, and a possibility signal of losing god Is stored (output) in a memory such as a RAM (S1690), and the walking / stop random short-term repetition determination process is terminated.

  According to the walking / stop random short-term repeated determination process executed by the aged pendant 1 as described above, by detecting the motion of walking and the motion of stopping as a specific pattern in the motion of the person being monitored. Since it is determined whether or not the monitoring target person is in a state of loss of spirituality, it is possible to more reliably detect the wrinkle of the monitoring target person.

[Random short-time repeated judgment process for walking, left and right turns]
Next, the random short time repeat determination process of walking / left / right turns will be described with reference to FIG. FIG. 44 is a flowchart showing a random short-time repetition determination process of walking / left / right turn executed by the MPU 51 of the rescue request signal transmission device 50.

  The walk / left / right turn random short-term repetition determination process is a process executed during the above-described wrinkle determination process (FIG. 42). First, the walking signal and the right turn signal stored in the memory are processed. , And a left turn signal is acquired (input) (S1710 to S1720).

  Then, the change from the walking signal to the right turn signal and the change from the walking signal to the left turn signal are extracted (S1725), and whether or not the change from the walking signal to the right (left) turn signal is detected. Is determined (S1730). If the change from the walking signal to the right (left) turn signal is not detected (S1730: No), the random short-time repeat determination process for walking / left / right turns is terminated.

  Moreover, if the change from the signal during walking to the right (left) turn signal is detected (S1730: Yes), the number of changes from the signal during walking to the signal during stop for 1 minute (within the second mind loss determination time) Is stored in a memory such as a RAM (S1735). Then, it is determined whether or not the number of changes per minute is 6 times (second mind loss threshold) (S1740: mind loss determination means).

  If the number of changes from the walking signal to the right (left) turn signal in less than one minute is less than 6 (S1740: No), the random short time repeat determination process for walking, left, and right turns is terminated. Further, if the number of changes from the walking signal in one minute to the right (left) turn signal is 6 times or more (S1740: Yes), it is assumed that the person to be monitored may be in a state of loss of godliness. The possibility signal is stored (output) in a memory such as a RAM (S1745), and the walking / left / right turn random short-term repetition determination process is terminated.

  According to such a random short-time repeated determination process of walking / left / right turn executed by the pendant 1 for elderly people, as a specific pattern in the operation of the monitoring subject, from the walking operation to the right turn (forward turn) and Since it is determined whether or not the person to be monitored is in a state of losing heart by detecting an operation of making a left turn (reverse direction turn), it is possible to more reliably detect the eyelid of the person to be monitored.

[Random short-time repeated judgment process of walking / sitting]
Next, the random short-time repeated determination process for walking / sitting operation will be described with reference to FIG. FIG. 45 is a flowchart showing a random short-time repeated determination process of walking / sitting operation executed by the MPU 51 of the rescue request signal transmission device 50.

  The random short time repeated determination process of walking / sitting movement is a process executed during the above-described wrinkle determination process (FIG. 42). First, the walking signal and the sitting movement signal stored in the memory are processed. Obtain (input) (S1760 to S1765).

  Then, a change from the walking signal to the sitting motion signal is extracted (S1770), and it is determined whether a change from the walking signal to the sitting motion signal is detected (S1775). If a change from the walking signal to the sitting motion signal is not detected (S1775: No), the random short-time repeated determination process for the walking / sitting motion is terminated.

  Further, if a change from the walking signal to the sitting motion signal is detected (S1775: Yes), the number of changes from the walking signal to the sitting motion signal for 1 minute (within the third god loss determination time) is stored in RAM or the like. (S1780). Then, it is determined whether or not the number of changes per minute is equal to or greater than 3 (third mind loss threshold) (S1785: mind loss determination means).

  If the number of changes from a walking signal to a sitting motion signal in less than one minute is less than 3 (S1785: No), the random short-time repeated determination process for walking / sitting motion is terminated. Further, if the number of changes from the walking signal to the sitting motion signal in one minute is 3 or more (S1785: Yes), it is assumed that the person to be monitored may be in a state of losing god, and a possibility signal of losing god. Is stored (output) in a memory such as a RAM (S1790), and the random short-time repeated determination process for the walking / sitting operation is terminated.

  According to such a random short-time repeated determination process of the walking / sitting operation performed by the elderly pendant 1, the monitoring target person is detected by detecting the sitting action from the walking action as a specific pattern in the monitoring target person's action. Therefore, it is possible to more reliably detect the wrinkle of the monitoring subject.

[Standby registration process]
Next, the process of registering the turnaround destination (visit destination) of the monitoring subject in the elderly pendant 1 will be described with reference to FIG. FIG. 46 is a flowchart illustrating a turnaround destination registration process executed by the MPU 51 of the rescue request signal transmission device 50.

  This turnaround destination registration process is a process that is started periodically (for example, every 10 ms). First, a signal is input to switch to the learning mode by operating the operation unit 70 (touch pad 71, confirmation button 73). Is received (S1810: mode switching means). When the MPU 51 of the support control request signal transmission device 50 receives a signal to switch to the learning mode, the MPU 51 switches from the normal mode in which the various processes described above are performed to the learning mode in which the turnaround destination is registered.

  Subsequently, it is determined whether or not the current mode is a learning mode (S1815). If the current mode is the learning mode (S1815: Yes), information on the current location of the pendant 1 for the elderly detected by the GPS receiver 27 is input (S1820). The current location information is stored in the visited memory 55 as a turnaround destination (S1825), and the turnaround destination registration process ends.

  If the current mode is not the learning mode (S1815: No), the current location information of the pendant 1 for the elderly detected by the GPS receiver 27 is input (S1830), and the turnaround destination stored in the visited memory 55 Is read out (S1835).

  Then, whether or not the distance between the present location of the pendant 1 for the elderly detected by the GPS receiver 27 and the position of the turn-around destination stored in the visited memory 55 is more than 100 m (predetermined distance). Determination is made (S1840). If the distance between the current location of the pendant 1 for the elderly and the position of the turnaround is less than 100 m (S1840: No), the turnaround registration process is terminated.

  If the distance between the current location of the pendant 1 for the elderly and the position of the destination is 100 m or more (S1840: Yes), information on the current location of the pendant 1 for the elderly is temporarily registered in a memory such as a RAM (S1845). . When information on the current location of the pendant 1 for the elderly is temporarily registered in the memory, the number of temporary registrations at the same temporary registration position (for example, a temporary registration position within 100 m) and registration date information are registered together. .

  Subsequently, it is determined whether or not the temporarily registered information satisfies a main registration condition (for example, when temporary registration at the same position is performed for five different days) (S1850). If the provisionally registered information does not satisfy the main registration condition (S1850: No), the turnaround destination registration process is terminated.

  Further, if the temporarily registered information satisfies the main registration condition (S1850: Yes), the temporarily registered point is stored in the visited memory 55 as a turnaround destination (S1855), and the turnaround destination registration process is terminated.

  In this processing, the processing of S1815 to S1825 corresponds to the first storage control means in the present invention, and the processing of S1830 to S1855 corresponds to the second storage control means in the present invention.

  According to the turnaround destination registration process executed by the elderly pendant 1, the monitoring target person or the guardian of the monitoring target person operates the operation unit at the turnaround destination of the monitoring target person and switches to the learning mode. The turnaround destination can be registered as a turnaround destination visited by the monitoring target person. That is, the turnaround destination can be registered without requiring complicated work such as inputting position information. In addition, even in the normal mode, the monitoring target person and his / her guardian can particularly perform operations because the monitoring target person frequently visits (the number of times equal to or greater than the registration threshold) can be registered as location information. It is possible to register a turnaround without having to.

  In this process, when the mode is automatically switched to the learning mode, the current location information is stored in the visited memory 55 as the visiting location information, but for example, the mode is switched to the learning mode. In addition, when the operation unit is operated, the current location information may be stored in the visited memory 55 as the location information of the destination.

[Safety judgment possible judgment processing]
Next, a process for determining whether or not the elderly pendant 1 is in a state in which it is possible to determine the safety of the monitoring subject will be described with reference to FIG. FIG. 47 is a flowchart illustrating the safety determination possible determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This safety determination possibility determination process is a process that is activated at predetermined intervals that are set in advance. First, an output from the three-dimensional acceleration sensor 11 is input (S1910), and the output of the sensor 11 changes. It is determined whether or not (S1915). If there is a change in the output of this sensor 11 (S1915: YES), a safety judgment possible signal is outputted as being able to judge the safety of the monitoring subject (S1930), and the safety judgment possible judgment process is terminated.

  If there is no change in the output of the sensor 11 (S1915: NO), the background contact state signal, the background contact clothing outside state signal, the background contact clothing inside signal, the background non-contact state signal, the background non-contact outside clothing state signal. , And a non-texture-in-clothing state signal are detected (S1920), and it is determined whether or not any of these signals has been input (whether it has been detected) (S1925).

  If any signal is input (S1925: YES), a safety judgment possible signal is output (S1930), and the safety judgment possible judgment process is terminated. If no signal is input (S1925: NO), a safety judgment impossibility signal is output (S1935) assuming that the safety of the monitoring subject cannot be judged, and the safety judgment possible judgment process is terminated.

[Safety state judgment processing (related to pulse rate)]
Next, a process for determining the safety of the monitoring subject based on the monitoring subject's pulse rate related information will be described with reference to FIG. FIG. 48 is a flowchart showing a pulse rate-related safety state determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This pulse rate-related safety state determination process is a process that is activated at predetermined intervals set in advance, and first determines whether or not a safety determination enable signal is output (S1960). If the safety determination possible signal is not output (S1960: NO), the pulse rate related safety state determination processing is immediately terminated.

  On the other hand, if the safety determination possible signal is output (S1960: YES), the output from the electrocardiographic sensor 33 is acquired (S1965), and the heart rate of the monitoring subject is calculated based on the output from the electrocardiographic sensor 33. Calculate (S1970). In this process, for example, the heart rate for the past 5 seconds is calculated.

  Then, a weighted average value obtained by adding 90% of the past heart rate by the electrocardiographic sensor 33 and 10% of the heart rate calculated in S1970 is obtained, and a value 12 times the weighted average value (that is, per minute) Is recorded as a heart rate by the electrocardiographic sensor 33 in a memory such as a RAM (S1975). The weighted average value calculated in this process is used as the “past heart rate” described above when the safety state determination process is performed again.

  Subsequently, the output from the heart sound sensor 35 is acquired (S1980), and a weighted average value obtained by adding 90% of the past heart rate by the heart sound sensor 35 and 10% of the heart rate calculated in S1985 is obtained. A value 12 times the weighted average value (that is, a value per minute) is recorded as a heart rate by the heart sound sensor 35 in a memory such as a RAM (S1985).

  Then, it is determined whether or not the heart rate by the electrocardiographic sensor 33 (electrocardiographic heart rate) and the heart rate by the heart sound sensor 35 (heart sound heart rate) substantially coincide (whether there is consistency) (S1990). : Consistency determination means). Here, since the purpose of this process is to confirm that the electrocardiogram sensor 33 and the heart sound sensor 35 are functioning, “generally match” means that the electrocardiogram sensor 33 and the heart sound sensor 35 function. It is only necessary to be set within a range where it can be confirmed. In addition, about a concrete numerical value, it should obtain | require experimentally.

  If the electrocardiogram heart rate and the heart sound pulse rate do not substantially match (S1990: NO), a heart rate unknown signal indicating that the heart rate is not reliable and the heart rate is unknown is output (S1995: matched). Sex determination means), the pulse rate-related safety state determination process is terminated. On the other hand, if the electrocardiogram heart rate and the heart sound heart rate substantially match (S1990: YES), the average value of the electrocardiogram heart rate and the heart sound heart rate is recorded in a memory such as a RAM as the heart rate of the monitoring subject. (S2000).

  Then, it is determined whether or not the heart rate of the monitoring subject recorded in S2000 is excessive (S2005), or whether it is excessive (S2015) (heart rate determination means). That is, it is determined whether or not the heart rate of the monitoring subject is higher than a preset upper limit heart rate or less than a preset lower limit heart rate.

  If the heart rate of the monitoring subject is higher than the upper limit heart rate (S2005: YES), it is determined that the heart rate is excessive, an excessive heart rate signal is output (S2010), and a pulse rate related safety state determination process is performed. finish. If the heart rate of the monitoring subject is less than the lower limit heart rate (S2015: YES), it is determined that the heart rate is too low, and an under heart rate signal is output (S2025), and the pulse rate related safety state is determined. The process ends.

  Further, if the heart rate of the monitoring subject is within the range of the upper limit heart rate and the lower limit heart rate (S2005: NO, S2015: NO), it is determined that the heart rate is normal, and a normal heart rate signal is output, The safety rate determination process related to the pulse rate is terminated.

According to the above-described safety rate determination process related to the pulse rate, it is possible to determine whether or not an abnormality has occurred in the monitoring target person based on the heart rate of the monitoring target person.
Also, according to the pulse rate-related safety state determination process, the heart rate of the monitoring subject is detected by a plurality of means, and if the detected heart rate is not consistent, it is determined that the heart rate is unknown. As a result, the reliability of heart rate detection can be improved.

[Safety status judgment process (body temperature)]
Next, a process for determining the safety of the monitoring subject based on the temperature related information of the monitoring subject will be described with reference to FIG. FIG. 49 is a flowchart showing a body temperature-related safety state determination process executed by the MPU 51 of the rescue request signal transmission device 50.

  This body temperature-related safety state determination process is a process that is activated at predetermined intervals set in advance, and first determines whether a safety determination possible signal is output (S2060). If the safety determination possible signal is not output (S2060: NO), the body temperature related safety state determination processing is immediately terminated.

  On the other hand, if the safety determination possible signal is output (S2060: YES), it is determined whether the background contact state signal is output (S2065). If the background contact state signal is not output (S2065: NO), a body temperature unknown signal indicating that the body temperature cannot be detected is output (S2070), and the body temperature related safety state determination process is terminated.

  If the background contact state signal is output (S2065: YES), the output from the temperature sensor 15 on the back surface is acquired (S2075), 90% of the past body temperature (body temperature per minute), and S2075. A weighted average value obtained by adding 10% of the acquired body temperature values is obtained, and the weighted average value is recorded in a memory such as a RAM as the body temperature of the monitoring subject (S2080). Note that the weighted average value calculated in this process is used as the “past body temperature” when the safety state determination process is performed again.

  Then, it is determined whether or not the body temperature of the monitoring subject recorded in S2080 is excessive (S2085) or is excessive (S2095). That is, it is determined whether the body temperature of the monitoring subject is higher than a preset upper limit body temperature or lower than a preset lower limit body temperature.

  If the body temperature of the monitoring subject is higher than the upper limit body temperature (S2080: YES), the body temperature of the monitoring subject is assumed to be too high, an overtemperature signal is output (S2090), and the body temperature related safety state determination processing is terminated. Also, if the body temperature of the monitoring subject is lower than the lower limit body temperature (S2080: YES), the body temperature of the monitoring subject is assumed to be too low, and an underbody temperature signal is output (S2105), and the body temperature-related safety state determination processing ends. To do.

  If the body temperature of the monitoring subject is within the range between the upper limit body temperature and the lower limit body temperature (S2085: NO, S2095: NO), a body temperature normal signal is output assuming that the body temperature of the monitoring subject is normal (S2100). ), Body temperature-related safety state determination processing is terminated.

According to the body temperature-related safety state determination process as described above, it is possible to determine whether an abnormality has occurred in the monitoring target person based on the body temperature of the monitoring target person.
[Relief request determination process (voice)]
Next, processing for outputting a signal for requesting rescue of the monitoring subject based on the voice of the monitoring subject will be described with reference to FIG. FIG. 50 is a flowchart showing a relief request determination process related to voice executed by the MPU 51 of the relief request signal transmission device 50.

  This relief request determination process is a process that is activated at predetermined intervals set in advance. First, an audio signal from the microphone 37 is acquired (S2110), and surrounding sounds are captured as data (S2115). Then, the registered sound data of the monitoring subject registered in advance (such as “help” and “help” voices and moans recorded by the monitoring subject) are compared with the captured data (S2120). It is determined whether or not the sound data matches any of the registered sounds (S2125: voice match determination means).

  If the surrounding sound data matches any of the registered sounds (S2125: YES), a rescue request signal is output (S2130: second rescue determination means), and then the rescue request determination process ends. Further, if the surrounding sound data does not match any of the registered sounds (S2125: NO), the rescue request determination process is immediately terminated.

  According to such a relief request determination process, for example, it is possible to detect a specific pattern of the monitoring target person such as “help”, “help”, or moaning, so it is necessary to rescue the monitoring target person. Can be determined.

[Caution state setting process]
Next, the attention state setting process will be described with reference to FIG. FIG. 51 is a flowchart showing attention state setting processing executed by the MPU 51 of the rescue request signal transmission device 50. Here, the attention state is not the level of requesting relief at the present time, but when the person to be monitored feels uncomfortable, such as physical condition, the relief is automatically carried out so that the rescue can be requested early. This represents a state in which the threshold value for determining whether or not to change is changed.

That is, when the attention state is set, the relief request execution process described later can request the rescue earlier than the case where the attention state is not set.
Here, the attention state setting process is a process that is activated at predetermined intervals set in advance, and first, it is determined whether or not a safety determination possible signal is output (S2160). If the safety judgment possible signal is not output (S2160: NO), the attention state setting process is immediately terminated.

  On the other hand, if the safety determination possible signal is output (S2160: YES), the output from the fingerprint sensor 75 is acquired (S2165), and the output is captured as data (S2170). Then, comparison is made with the fingerprint data (registered fingerprint) of the monitored person registered in advance (S2175), and the captured data matches the registered fingerprint (one of them if there are multiple registered fingerprints). It is determined whether or not to perform (S2180).

  If the captured data matches the registered fingerprint (S2180: YES), an attention state inversion signal is output (S2185), and the attention state setting process is terminated. When the attention state inversion signal is output in this way, the attention state is released from the attention state cancellation state, or the attention state setting state is changed to the attention state cancellation state.

On the other hand, if the captured data does not match the registered fingerprint (S2180: NO), the attention state setting process is immediately terminated.
According to such a portable monitoring device, since it is not possible to input to the device that a person other than the monitoring target person does not need relief, the will of the monitoring target can be respected.

  In the present embodiment, the fingerprint sensor 75 is used to detect the physical characteristics of the monitoring target person. However, authentication of whether or not the physical characteristics of the specific monitoring target person registered in advance matches. Means capable of implementing can be substituted.

[Caution state reversal processing]
Next, the attention state inversion process will be described with reference to FIG. FIG. 52 is a flowchart showing attention state reversal processing executed by the MPU 51 of the rescue request signal transmission device 50.

  The attention state reversal process is a process based on the above-described attention state setting process, and is activated every predetermined period set in advance. In this attention state determination process, first, an attention state inversion signal is input (detected) (S2210), and it is determined whether or not an attention state inversion signal is input (S2215).

  If the attention state inversion signal has not been input (S2215: NO), the attention state inversion processing is immediately terminated. If the attention state inversion signal is input (S2215: YES), it is determined whether or not the attention state is currently set (S2220). If the attention state is set (S2220: YES), the processing for canceling the attention state is performed. That is, the normal state signal is output (S2225), the caution state display (details will be described later) displayed on the display 61 is deleted (S2230), and the caution state inversion process is terminated.

  If not set to the caution state (S2220: NO), a process for setting the caution state is performed. That is, a caution state signal is output (S2235), a caution state display for displaying a mark for calling attention such as “!” On the display 61 is performed (S2240), and the caution state inversion process is terminated.

[Rescue Request Judgment Processing (Rescue Request Lever)]
Next, the relief request determination process regarding the relief request lever 77 will be described with reference to FIG. FIG. 53 is a flowchart showing a rescue request determination process related to the rescue request lever 77 executed by the MPU 51 of the rescue request signal transmission device 50. This relief request determination process is a process that is activated at predetermined intervals that are set in advance. First, the state of the relief request lever 77 is input (S2260).

  Here, the relief request lever 77 will be described with reference to FIG. FIG. 54 is an explanatory view showing the operation mode of the relief request lever 77. The relief request lever 77 is disposed on the side surface of the housing 5 constituting the elderly pendant 1 (see FIG. 2A), and is configured to be rotatable about the lower portion of the relief request lever 77 as a fulcrum. .

  That is, the relief request lever 77 is normally stored in the same plane as the side surface of the aged pendant 1 (see FIG. 54A), and once in the back (housing 5). (See FIG. 54 (b)), it is popped out to the near side by the action of a spring (not shown) (see FIG. 54 (c)), and is further displaced by the operation of the person being monitored. That is, the rescue request lever 77 is configured to rotate 180 degrees from the stored state (see FIG. 54D). Then, the MPU 51 of the rescue request signal transmitting device 50 is configured to detect that the rescue request lever 77 is in the pulled-out state when the rescue request lever 77 is displaced by approximately 90 degrees or more from the housed state.

  In the configuration of the relief request lever 77 as described above, the relief request lever 77 cannot be brought into the pulled-out state unless the two operations of pushing in and then pulling out are performed. Compared to a case where the switch is configured as a button type switch for detecting a state, malfunction can be prevented.

  Now, returning to FIG. 53, when the state of the rescue request lever 77 is input, it is determined whether or not the rescue request lever 77 is operated (is in a pulled-out state) (S2265). If the rescue request lever 77 has been operated (S2265: YES), a rescue request signal is output (S2270: third rescue judgment means), and the rescue request judgment process related to the rescue request lever 77 is terminated.

If the rescue request lever 77 is not operated (S2265: NO), the rescue request determination process for the rescue request lever 77 is immediately terminated.
According to such a relief request determination process, it is possible to immediately request a relief request at the will of the monitoring subject.

[Relief request execution process]
Next, a process for actually transmitting a rescue request will be described with reference to FIG. FIG. 55 is a flowchart showing a relief request execution process executed by the MPU 51 of the relief request signal transmission device 50.

  This relief request execution process is a process that is activated at predetermined intervals set in advance, and first, it is determined whether or not a relief request signal is output (S2310). If the rescue request signal is output (S2310: YES), the current location information is acquired, and the current location information, the identification information (ID, name, etc.) for identifying the monitoring target person, and the rescue including the rescue request message A request mail is generated, and this mail is transmitted to a preset contact (S2315). And when this process is complete | finished, a relief request execution process is complete | finished.

  Moreover, if the relief request signal is not output (S2310: NO), it will be determined whether the attention state signal is output (S2320: will detection change means). If an attention state signal is output (S2320: YES), it is determined whether any of an under heart rate signal, an over heart rate signal, an under body temperature signal, or an over body temperature signal is output (S2325, S2330, S2335, S2340).

  If any of an under heart rate signal, an over heart rate signal, an under body temperature signal, or an over body temperature signal is output (YES in any of S2325, S2330, S2335, and S2340), transmission intention confirmation processing 1 described later is performed. It carries out (S2345) and ends the rescue request execution process. Further, if none of the heart rate under-signal, heart-rate over-signal, under-temperature signal, or over-temperature signal is output (NO in all of S2325, S2330, S2335, and S2340), the rescue request execution process is immediately terminated. .

  On the other hand, even when the attention state signal is not output (S2320: YES), it is determined whether any of the heart rate under-signal, the heart rate over-signal, the body temperature under-signal, or the body temperature over-signal is output ( S2350, S2355, S2360, S2365).

  However, if any of an under heart rate signal, an over heart rate signal, an under body temperature signal, or an over body temperature signal is output (YES in any of S2350, S2355, S2360, and S2365), Performs a different transmission will confirmation process 2 described later (S2370), and ends the rescue request execution process. Further, if none of the heart rate under-signal, heart-rate over-signal, under-temperature signal, or over-temperature signal is output (NO in all of S2350, S2355, S2360, and S2365), the rescue request execution process is immediately terminated. .

Next, the transmission will confirmation process 1 will be described with reference to FIG. FIG. 56 is a flowchart showing the intention confirmation process 1 for transmission.
In the transmission intention confirmation process 1, first, an announcement is made via the speaker 65 that the relief request is to be implemented after 30 seconds and that the relief request is to be canceled within 30 seconds (S2410). . At this time, the content of the same purpose is also displayed on the display 61.

  Then, the output from the fingerprint sensor 75 is acquired (S2415), and the output is captured as data (S2420). Then, comparison is made with the fingerprint data (registered fingerprint) of the monitored person registered in advance (S2425), and the captured data matches the registered fingerprint (one of them if there are multiple registered fingerprints). It is determined whether or not to perform (S2430: intention confirmation means).

  If the captured data matches the registered fingerprint (S2430: YES), it is determined that there is an intention to cancel the rescue request, and the transmission intention confirmation process is immediately terminated. If the captured data matches the registered fingerprint, a relief request grace signal is output, and a relief request is made excluding a relief request based on the will of the person being monitored for a preset time (for example, about 30 minutes). You may make it not.

  On the other hand, if the captured data does not match the registered fingerprint (S2430: NO), it is determined whether 30 seconds have elapsed after the start of this process (S2435). If 30 seconds have elapsed (S2435: YES), the present location information is acquired, and the present location information, identification information (ID, name, etc.) for identifying the monitoring target person, and a rescue request message including a rescue request message A mail is generated, and this mail is transmitted to a preset contact (S2440). When this process ends, the transmission will confirmation process 1 ends.

  If 30 seconds have not elapsed in the processing of S2435 (S2435: NO), a countdown announcement until the rescue request is transmitted is executed via the speaker 65 (S2440), and the processing returns to S2415.

Next, the will confirmation process 2 for transmission will be described with reference to FIG. FIG. 57 is a flowchart showing the intention confirmation process 2 for transmission.
In the transmission intention confirmation process 2, processing similar to the transmission intention confirmation process 1 is generally performed. However, in the transmission confirmation process 1, “30 seconds” is adopted as the threshold value in S2410 and S2435, whereas in the transmission confirmation process 2, “30 seconds” is longer than “30 seconds”. “5 minutes” is adopted. In other words, if the attention state signal is output, the rescue request is set to be transmitted more quickly.

  According to such a relief request execution process, by authenticating the fingerprint, it is possible to set a time until only a registered person such as the person to be monitored performs a relief request. For this reason, for example, the person to be monitored can change the will detection time according to his / her physical condition. Moreover, the time until the rescue request is carried out can be changed according to the monitoring subject.
