Description

  The present invention relates to a slide-down response processing apparatus, a timepiece, and a slide-down response processing method for performing a slide-down response procedure for notifying a slip that has occurred during mountain climbing.

  Conventionally, a transmitter for detecting the position of a mountain victim has been known (for example, see Patent Document 1).

  The transmitter described in Patent Document 1 is a device that transmits a super-single wave of 50 to 54 megahertz, and the position of the victim is specified by receiving the radio wave with a receiver possessed by a rescuer. The structure to do is taken.

Japanese Patent Laid-Open No. 2-203290

  By the way, in the conventional apparatus as described in the above-mentioned Patent Document 1, it is necessary for the victim to operate the transmitter to transmit the transmitted radio wave. However, there is a problem that when the climber cannot move due to sliding or the like when climbing, or in an unconscious state, the transmitted radio wave cannot be transmitted, and the fact that the skidding has occurred cannot be notified.

  The present invention has been made in view of the above problems, and has an object to provide a slip-down response processing device, a timepiece, and a slide-down response processing method capable of notifying a slip even when a climber cannot move. And

In the slipping correspondence processing apparatus of the present invention, an altitude detecting means for detecting an altitude, an altitude change calculating means for calculating an altitude change per unit time, and whether the altitude change is equal to or greater than a predetermined reference change Slipping judgment means for judging whether or not, and when the sliding judgment means judges that the amount of change in altitude is greater than or equal to the reference change amount, slipping handling processing means for performing slipping handling processing for notifying the occurrence of sliding It is characterized by comprising.
Further, in the slipping correspondence processing method of the present invention, an altitude is detected, an altitude change amount per unit time is calculated from the detected altitude, and whether or not the altitude change amount is equal to or greater than a predetermined reference change amount. When the altitude change amount is determined to be greater than or equal to the reference change amount, a slip-down handling process for notifying the occurrence of a slip-down is performed.

According to these inventions, the current altitude of the climber is detected by the altitude detecting means, and the altitude change amount per unit time is calculated by the altitude change amount calculating means. Then, when the altitude change amount per unit time exceeds the reference change amount, the slippage determination means determines that there is a slippage, and the slippage response processing means performs a slippage response process.
That is, when sliding occurs, the altitude decreases at a sufficiently high speed compared to when walking down the slope by walking or the like. Therefore, it is possible to determine whether or not there is a slipping by determining whether or not the altitude change amount is larger than a predetermined reference change amount set in advance. Then, when it is determined that there has been a sliding down, the sliding down handling processing is performed by the sliding down handling processing means. Here, as the slip-down processing, for example, a sound such as an alarm sound may be generated to notify that a slip-off has occurred in the surroundings. It is good also as a structure which transmits that the sliding had generate | occur | produced.
As described above, according to the present invention, it is possible to reliably detect the presence or absence of sliding according to a change in altitude, and to notify the surroundings that a sliding has occurred automatically when there is a sliding. Therefore, even when the slipper is unable to act, such as when the slipper is not conscious, the occurrence of the slip accident can be notified to the surroundings. In particular, when the slider is unconscious, it is necessary to carry out rescue activities earlier and take necessary measures. However, in a configuration where the slidable response process is performed manually, the slidable person must perform the slidable response process. The rescuer finds a slipper and rescues a delay. On the other hand, in the present invention as described above, since it is possible to immediately inform the surroundings of the occurrence of the sliding after the occurrence of the sliding, the position of the sliding person can be easily identified, and the rescue operation can be performed quickly. Can do.

  The sliding down response processing apparatus of the present invention includes acceleration detecting means for detecting acceleration, and the sliding down response processing means is predetermined after the altitude change amount is determined to be greater than or equal to the reference change amount by the slippage determining means. It is preferable that the sliding-off countermeasure processing is performed when no acceleration is detected by the acceleration detection means within a time period.

According to the present invention, after acceleration, if the acceleration is detected within a predetermined time by the acceleration detecting means, the anti-sliding processing means does not perform the anti-sliding processing and performs the anti-sliding processing when no acceleration is detected. carry out. That is, there are cases where a person who slides down can move even after sliding down. In this case, for example, by performing an operation such as moving an arm on which the processing apparatus for handling sliding down is performed, the acceleration is detected by the acceleration detecting means. Do not take action. That is, since it can be determined that the slipper is safe, the power consumption can be suppressed by not performing the slipping response process and not performing the unnecessary notification process.
On the other hand, in the sliding degree, for example, when there is no consciousness of the sliding person or when the arm wearing the sliding handling device is injured such as a fracture, the acceleration is not detected. In such a case, the slipper is unable to move, and when the slipping response processing means determines that no acceleration is detected within a predetermined time, the slipping response processing is performed. Therefore, in an emergency where the slipper cannot move, it is possible to inform the surroundings of the fact that the slipper has occurred quickly, so that the rescuer can be rescued more quickly.

  In the slippage processing apparatus of the present invention, whether or not there is a change in the altitude detected by the altitude detection means within a predetermined time after the altitude change amount is determined by the slippage determination means to be greater than or equal to the reference change amount. It is preferable that the altitude change determining means for determining whether the altitude change determining means performs the anti-sliding response process when the altitude change determining means determines that there is no altitude change within a predetermined time. .

According to the present invention, it is possible to determine whether or not the slipper is movable by determining whether or not there is a change in the altitude detected by the altitude detecting means. That is, when the altitude change determining means determines that there is an altitude change after sliding down, it can be determined that the slipper has started climbing or descending after sliding down, and it can be considered that damage due to sliding down is small. In such a case, the sliding-down countermeasure processing means can prevent unnecessary notification without notifying the surroundings that the sliding has occurred, and can save power.
On the other hand, if there is no change in altitude after sliding down, it can be determined that the slipper is in a state where it is impossible to climb or descend. Further, as in the above invention, even when acceleration is detected by the acceleration detecting means, if there is no change in altitude, for example, the arm can be moved, but it cannot move due to a fracture or the like. Even when such movement is impossible, quick rescue is required. In contrast to the above-described case, the slip-down handling apparatus according to the present invention performs the slip-down handling process when there is no altitude change for a predetermined time or more. For this reason, it is possible to immediately determine whether or not movement is possible after sliding down regardless of whether or not there is consciousness. Can help the rescuer quickly.

  The slipping-down processing apparatus of the present invention includes an acceleration detecting means for detecting acceleration, and the acceleration detecting means within a predetermined time after the altitude change amount is determined to be greater than or equal to the reference change amount by the slipping determining means. Acceleration determining means for determining whether or not the detected acceleration in a predetermined direction has continued to act for a predetermined time, and the slip-off response processing means is configured to have an altitude within a predetermined time by the altitude change determining means. When it is determined that there is no change, and the acceleration determination means determines that the acceleration is not continuously applied within a predetermined time, it is preferable to perform the sliding-off countermeasure processing.

  According to the present invention, it is determined not only whether or not there is a change in altitude as described above, but also whether or not the acceleration detected by the acceleration detecting means is continued for a predetermined time after sliding down. That is, there is a case where a flat surface is moved after sliding down. In this case, in the above configuration, since there is no change in altitude after sliding down, it is determined that the slipper cannot move. On the other hand, in the present invention, it is possible to determine whether or not the slipper has moved on the flat surface by detecting the acceleration, and to detect the state of the slipper after the slip more accurately. It is possible to prevent erroneous slipping prevention processing.

  A timepiece according to the present invention includes the above-described slip-down handling processing device, the slip-down handling processing device, a time counting unit that counts time, and a display unit that displays the time counted by the time counting unit. And

  In the present invention, the above-described slip-down handling apparatus is mounted on a timepiece such as a wristwatch that displays time. Therefore, it is possible to carry out relief support at the time of sliding down simply by wearing a watch. In addition, since the slip-down processing device is mounted on a lightweight and easy-to-wear watch, it does not get in the way when climbing and the portability is also good.

  Hereinafter, a wristwatch equipped with a slip-down handling apparatus according to an embodiment of the present invention will be described with reference to the drawings.

[Clock structure]
FIG. 1 is a block diagram showing a schematic configuration of a timepiece equipped with a slip-down handling apparatus according to an embodiment of the present invention.
In FIG. 1, a timepiece 1 includes an exterior case (not shown) and a module 2 that is housed in the exterior case and functions as a slip-down handling apparatus according to the present invention. This timepiece 1 is a so-called wristwatch, and a band that can be attached to a user's arm is provided on an exterior case. As shown in FIG. 1, the module 2 of the timepiece 1 includes a display unit 11, an altitude sensor 12 as an altitude detecting unit, an acceleration sensor 13 as an acceleration detecting unit, a time measuring unit 14, and an input unit 15. , A notification unit 16 that constitutes a sliding-down handling means, a storage unit 17, and a CPU (Central Processing Unit) 20.

  The display unit 11 is provided on the upper surface side of the exterior case, and displays the time outward through a transparent member such as transparent glass. The display unit 11 may display time using a small and thin digital display means such as a liquid crystal panel display or an organic EL (Organic Electro-Luminescence) display. The time may be displayed by driving the pointer with a mainspring or the like.

  The altitude sensor 12 detects the altitude from the sea level at the current position, that is, the absolute altitude, by measuring the atmospheric pressure. In the present embodiment, the altitude sensor 12 that detects the absolute altitude is illustrated, but the present invention is not limited to this. A configuration for detecting altitude may be used. The altitude sensor 12 then outputs an altitude signal corresponding to the detected altitude to the CPU 20.

  The acceleration sensor 13 detects acceleration acting on the timepiece 1. In the present embodiment, since the wristwatch 1 is exemplified as a watch worn on the user's arm, acceleration is detected according to the movement of the user's arm.

  The timer unit 14 counts time (hour, minute, second) based on a pulse signal output from a pulse synthesis circuit (not shown) provided in the module 2. Here, the pulse synthesizing circuit includes a reference oscillator such as a crystal oscillator, and generates a pulse signal by dividing the reference pulse output from the reference oscillator. This pulse synthesis circuit is connected to the CPU 20 and serves as a clock signal for the circuit. Then, the timer unit 14 counts the pulse signals input from the pulse synthesizing circuit and measures the current time. Note that an antenna that receives a standard radio wave may be provided and may have a radio wave correction function that automatically corrects the current time counted based on the received standard radio wave.

  The input unit 15 includes operation input means such as buttons and crowns, and outputs a predetermined operation signal to the CPU 20 when the operation input means is operated by a user.

  The notification unit 16 includes a speaker. For example, when a notification signal for notifying that a sliding accident has occurred is input from the CPU 20, the notification unit 16 controls the speaker to output, for example, an alarm sound. In this embodiment, an example in which the occurrence of a sliding accident is notified to the surroundings by an alarm sound is described. However, the present invention is not limited to this. For example, the notification unit 16 may be configured to transmit a beacon.

  The storage unit 17 stores a storage area for temporarily storing data calculated by the CPU 20, various programs developed on an OS (Operating System) that controls the entire module 2, and various data used in these programs. To do.

Next, a program calculated by the CPU 20 will be described. FIG. 2 is a diagram illustrating the configuration of various programs that are processed as software by the CPU 20.
As shown in FIG. 2, the program processed by the CPU 20 includes a sensor signal recognition unit 21, an altitude change calculation unit 22, a slippage determination unit 23, a post-sliding time count unit 24, and an altitude change determination unit 25. And an acceleration determination means 26 and a slippage notification control means 27 that constitutes the slippage handling processing means of the present invention together with the notification section 16 described above.

  The sensor signal recognition means 21 receives each signal output from the altitude sensor 12 and the acceleration sensor 13 and acquires the absolute altitude and acceleration at the current position. At this time, the sensor signal recognizing means 21 acquires the current absolute altitude and acceleration at predetermined time intervals, for example, every second. The acquired absolute altitude and acceleration are temporarily stored in the storage unit 17 together with the time counted by the time measuring unit 14, for example.

  The altitude change amount calculating means 22 calculates the altitude change amount per unit time (for example, the altitude change amount per second in the present embodiment) from the absolute altitude for each predetermined time acquired by the sensor signal recognition means 21. To do. In the present embodiment, since the absolute altitude is measured every second by the altitude sensor 12, the amount of change in altitude per second can be calculated by calculating the difference between the measured absolute altitudes. In addition, the altitude change calculation means 22 of the present embodiment calculates the altitude change with the vertically lower side as the positive direction. Therefore, in the state where the user is climbing the mountain toward the summit, the altitude change amount calculating means 22 calculates a negative value, and in the state where the user is descending or falls due to sliding down, A positive value is calculated.

The slippage determining means 23 determines whether or not a slippage has occurred based on the altitude change amount calculated by the altitude change amount calculating means 22. Specifically, the sliding-down determination unit 23 determines that there has been a sliding-down when the calculated altitude change amount per second is larger than a predetermined reference change amount. Here, an arbitrary value can be set as the reference change amount. However, the velocity in the direction of drop after 1 second (9.8 (m / s ² ) × 1) in the free fall of the object having an initial velocity of 0 m / s. By adopting (s) × 1 (s) × 1 / 2≈5.0 m), it is possible to more reliably determine the presence or absence of sliding.

  The after-sliding time counting unit 24 measures the time after the sliding when the sliding-down determining unit 23 determines that the sliding has occurred. Specifically, the after-sliding time counting means 24 starts counting the timing when the sliding judgment means 23 determines that the sliding has occurred, and the altitude change value calculated by the altitude change calculating means 22 becomes zero. As time, the time after sliding down is counted.

  The altitude change determining means 25 determines that there has been a skid by the skid judging means 23, and the altitude change is detected within a predetermined time (for example, 15 minutes) after the post-sliding time counting means 24 starts counting the time after the skid. Determine if there was. For this, the altitude change determination means 25 determines whether or not the absolute altitude acquired by the sensor signal recognition means 21 has changed. The altitude change determination means 25 may perform processing for determining whether there is a change in the altitude change amount calculated by the altitude change amount calculation means 22.

  Based on the acceleration acquired by the sensor signal recognition unit 21, the acceleration determination unit 26 determines whether or not the slipper is moving after sliding down. Specifically, the acceleration determining means 26 determines that the sliding has occurred by the sliding determination means 23, and after the time after sliding has been counted by the after-sliding time counting means 24, a predetermined state observation time (for example, 10 seconds). It is determined whether or not the acceleration in the predetermined direction has been acquired by the sensor signal recognition means 21 within. Here, when acceleration is detected, it can be determined that the timepiece 1 has moved, that is, the arm of the slipper wearing the timepiece 1 has moved, and can be regarded as a state in which the slipper can move. On the other hand, when the acceleration is not acquired (the acquired acceleration is 0), it can be regarded as an inoperable state such as a lack of consciousness of the slipper.

  In addition, when the acceleration determination unit 26 determines that the acceleration is acquired by the sensor signal recognition unit 21 within the state observation time and the slipper is in a movable state, the acceleration determination unit 26 further has a movement observation time (for example, 15 minutes). In addition, it is determined whether or not acceleration is continuously applied in a predetermined traveling direction for a predetermined period (for example, 1 minute). That is, when the user travels in a certain direction, even if the user moves while waving his arm, the acceleration in the traveling direction becomes larger than the acceleration in the other direction. Therefore, it is possible to determine that the user is moving in the traveling direction because the acceleration in the traveling direction detected by the acceleration sensor continues for a predetermined period.

The slip notification control means 27 notifies the notification unit 16 that a slip accident has occurred when it is determined that there is a slip and the slipper (user of the watch 1) cannot move. Is output. Thereby, the alerting | reporting part 16 controls a speaker, generates an alarm sound, and alert | reports that there was sliding down around.
Specifically, the slippage notification control unit 27 outputs a notification signal to the notification unit 16 when the acceleration determination unit 26 determines that no acceleration is acquired within the state observation time. In other words, if no acceleration is detected within the state observation time, it can be considered that the person is not able to move, such as being unconscious or not able to move even if there is consciousness. Rescue activities are required. In this case, the slip-down notification control unit 27 outputs a notification signal to the notification unit 16 immediately after the state observation time, and performs a slip-down response process for notifying the surroundings that a slip-down accident has occurred.

  Further, the slip-down notification control unit 27 determines that there is no change in altitude by the altitude change determination unit 25 within the movement observation time, and that no acceleration is continuously applied in a predetermined direction by the acceleration determination unit 26. If it is determined, it is determined that the slipper is incapable of moving, and a notification signal is output to the notification unit 16. That is, when acceleration is detected within the state observation time, it can be considered that the arm of the slipper is moving and is conscious. In such a case, it is further determined whether or not the slipper is in a movable state, and if it is incapable of moving, an alarm sound is output to notify the surroundings of the occurrence of the slipping accident. On the other hand, if the slipper is in a movable state, the alarm sound is not output and false alarms are prevented.

[Clock operation]
Next, regarding the operation of the timepiece 1 as described above, a slip-down countermeasure processing method will be described.
FIG. 3 is a flowchart of the slip-down handling process in the timepiece according to the present embodiment.

  In FIG. 3, the CPU 20 of the timepiece 1 activates the altitude sensor 12 when the operation signal for starting the mountain climbing is input by the operation of the input unit 15 of the user, for example, and calculates the absolute altitude every second. A measurement process is performed (step S101). The altitude change amount calculating means 22 calculates the altitude change amount by calculating the difference in absolute altitude detected in step S101 (step S102).

  Thereafter, the slippage judging means 23 judges whether or not the altitude change calculated in step S102 is equal to or higher than 5 m / s which is the reference change (step S103). Here, if it is determined in step S103 that the change amount is smaller than the reference change amount, the slipping-down determining unit 23 determines that there is no slipping, returns to step S101, and continues altitude measurement (normal operation).

  On the other hand, if it is determined in step S103 that the altitude change amount is larger than the reference change amount, the slippage determining means 23 determines that a slippage has occurred. In this case, the after-sliding time counting means 24 starts counting the after-sliding time at the timing when the altitude change amount becomes 0 (step S104).

Next, the CPU 20 drives the acceleration sensor 13 to measure the acceleration acting on the timepiece 1 (step S105).
Then, the acceleration determination means 26 refers to the time counted in step S104, and determines whether or not the acceleration is detected by the sensor signal recognition means 21 within the state observation time (10 seconds) (step S106). . If it is determined in step S106 that acceleration is not detected by the acceleration determining means 26 (acceleration is 0), it can be considered that the user is in an inoperable state due to the sliding down, so the sliding notification control means. 27 outputs a notification signal to the notification unit 16. Thereby, the alerting | reporting part 16 controls a speaker, generates an alarm sound, and alert | reports that the sliding accident occurred around (step S107).

On the other hand, when it is determined in step S106 that acceleration is detected within the state observation time by the acceleration determining means 26, it can be considered that the user is in a state where the user can act. In this case, the altitude change determination means 25 refers to the time counted in step S104 and determines whether or not there is a change in the absolute altitude detected by the altitude sensor 12 within the movement observation time (15 minutes). Judgment is made (step S108). In this step S108, when the altitude change determining means 25 determines that there is an altitude change, it can be considered that the user has resumed mountain climbing, and the routine returns to step S101 to continue the normal operation.
In step S108, when the altitude change determining unit 25 determines that there is no altitude change, the acceleration determining unit 26 further performs a process of determining whether or not the acceleration in a predetermined direction is continued for one minute. (Step S109). In step 109, if the acceleration determining means 26 determines that the acceleration has not continued for 1 minute, the processing of step S107 is performed, and the slip-down notification control means 27 outputs a notification signal to the notification unit 16, and the speaker Processing to generate an alarm sound from. If it is determined in step S109 that the acceleration continues for one minute, it can be considered that the user is moving in the horizontal direction. In this case, the process returns to step S101 and the normal operation is continued. To do.

[Effects of the present embodiment]
As described above, the timepiece 1 of the above embodiment calculates the altitude change amount by the altitude change amount calculating means 22 based on the altitude detected by the altitude sensor 12. Then, the slippage determining means 23 determines that a slippage has occurred when the altitude change amount is equal to or greater than the reference change amount, and the slippage notification control means 27 outputs a notification signal to the notification unit 16 to output an alarm sound. To notify the surroundings that slipping has occurred.
For this reason, even when the user who has slid down is unable to act due to the slid, it is possible to automatically notify the surroundings that the slid has occurred with an alarm sound. In addition, when sliding occurs, it is possible to quickly inform the surroundings that sliding has occurred, and it is possible to support the rescue operation of the sliding person quickly.

  Further, the timepiece 1 includes the acceleration sensor 13, and generates a warning sound from the notification unit 16 when it is determined by the sliding determination unit 23 that the sliding has occurred and the acceleration determining unit 26 determines that the acceleration is not measured. When the acceleration determination means 26 determines that the acceleration is measured, the alarm sound is not generated from the notification unit 16. That is, when it is determined that the acceleration is measured by the acceleration determining means 26, it can be considered that the slipper is conscious and the arm wearing the watch 1 is moved, and the slipper may resume movement by himself / herself. Is expensive. Therefore, in such a case, by not generating an alarm sound, unnecessary alarms can be eliminated, false alarms can be prevented, and power consumption of the timepiece 1 due to alarm activation can be suppressed. On the other hand, when the acceleration is not detected by the acceleration judging means 26, the arm wearing the watch 1 may not move due to a fracture or the like, and there may be no consciousness of the user who has slipped down, and prompt rescue is required. . In such a case, it is possible to promptly notify that there is a slipper injured by the occurrence of sliding down by promptly generating an alarm sound by the notification unit 16, and to perform quick rescue support for the sliding down person Can do.

  Furthermore, the timepiece 1 determines whether or not there has been an altitude change by the altitude change determination means 25 after the occurrence of sliding, and if there is no altitude change, the alarm unit 16 generates an alarm sound. That is, even if acceleration is observed within the state observation time immediately after the occurrence of slipping, if there is no change in altitude during the subsequent movement observation time, it is expected that the foot is injured and the movement is impossible. The Even in such a case, by generating an alarm sound from the notification unit 16, it is possible to inform the surroundings of the sliding down, and it is possible to support the rescue of the sliding down quickly. If it is determined by the altitude change determining means 25 that there is an altitude change, it can be determined that the slipper has already resumed climbing or has started descent by himself. In such a case, by not generating an alarm sound, unnecessary alarms can be eliminated, false alarms can be prevented, and power consumption of the timepiece 1 due to alarm activation can be suppressed.

  At this time, the timepiece 1 uses the acceleration determination unit 26 to determine whether or not the acceleration continues to act for one minute in a certain traveling direction. That is, even if the vehicle moves by itself after sliding down, if it moves on a flat surface that does not change in altitude, the altitude change determining means 25 determines that there is no altitude change. On the other hand, according to the above configuration, it is possible to determine whether or not the flat surface is moved by the acceleration determining means 26, and it is possible to reliably eliminate an unnecessary alarm when the slipper is safe.

  Further, the module 2 as the slip-down handling apparatus of the present invention is mounted on a timepiece 1 that is a wristwatch. In other words, the slip-corresponding processing apparatus can determine slipping by a simple process based on the altitude detected by the altitude sensor, so that the configuration is not complicated, and the altitude change calculation means 22 and the slipping determination are not complicated. Since the means 23, the after-sliding time counting means 24, the altitude change judging means 25, the acceleration judging means 26, and the slipping notification control means 27 are implemented as software, the configuration of a circuit or the like becomes unnecessary, and it is lightweight and small. It can be easily incorporated into a watch 1. Further, by incorporating the slip-down handling apparatus of the present invention into the watch 1, the user can easily wear the slip-down handling apparatus when climbing. Therefore, compared with the case where a dedicated slip-down handling device is stored in a mountaineering backpack or the like and carried around, it is always mounted on the mountaineering user's body. It is possible to deal with sliding down and the like, and it is possible to provide a sliding handling apparatus that is more practical. Further, since a wristwatch worn on the wrist is used as the watch 1, it is not lost during mountain climbing, and erroneous reports due to falling can be prevented.

That is, by detecting the acceleration that occurs when the user resumes climbing or descending a mountain, it is possible to detect movement associated with altitude change. Can be made easier.
