Referring to FIG. 4, in step S <b> 101, control unit 110 reads a detected value of acceleration in three axes indicated by a detection signal from acceleration sensor 170 and stores it in memory 120. The memory 120 sequentially stores the detected values of the acceleration in the three-axis directions for every predetermined period (for example, several ms, several tens of ms) of the predetermined period each time step S101 is executed.

  Next, in step S110, the control unit 110 executes an increase detection addition process. FIG. 5 is a flowchart showing the flow of the rise detection addition process executed by the activity meter in the first embodiment.

  Referring to FIG. 5, in step S <b> 111, control unit 110 determines whether or not the user wearing or possessing the activity meter has started to rise during walking such as stairs or hills.

  FIG. 7 is a graph showing a difference in index related to acceleration due to a difference in motion form. Referring to FIG. 7, in step S <b> 111 of FIG. 5, it is determined whether or not the user has started to rise as follows.

  First, 3 in the left-right direction (x-axis direction), the up-down direction (y-axis direction), and the front-rear direction (z-axis direction) obtained from the 3-axis acceleration sensor 170 stored in the memory 120 in step S101 of FIG. 4 described above. For the N detected values xi, yi, zi (i = 1 to N) in the latest short period indicated by two acceleration detection signals, the acceleration integration sums X, Y, Z are expressed by the following equations (1) to (3). Use to calculate.

  Next, a horizontal acceleration sum H obtained by combining accelerations in the left-right direction and the front-rear direction is calculated using Expression (4).

  Then, the ratio Y / H between the vertical acceleration sum Y and the horizontal acceleration sum H is calculated.

  As a result of the experiment, as shown in the graph of FIG. 7, when walking on a flat ground, the ratio of acceleration between the vertical direction and the horizontal direction is approximately 1: 1, and the value of Y / H is around 0.9. Indicates the value. Further, when going up the stairs, the vertical acceleration is larger than the horizontal acceleration, and the value of Y / H shows a value near 1.3.

  Based on the results of this experiment, by setting 1.1, which is the midpoint of the Y / H values in both cases, as a threshold value, if Y / H ≧ 1.1, it is determined that the user is climbing the stairs. When Y / H <1.1, it is determined that the user is walking on a flat ground.

  Here, the case of stair climbing and walking on a flat ground has been described, but the judgment based on the same experimental result can be made for the case of descending the staircase. Moreover, although the case where it walked was demonstrated, the judgment based on the same experimental result can be made also about the case where it drive | works.

  In the present embodiment, the determination as to whether or not the user has started to rise is made using the detection value of the acceleration sensor. However, the present invention is not limited to this, and the determination as to whether or not the user has started to rise may be made using the detection value of the atmospheric pressure sensor. Specifically, when rising starts, the atmospheric pressure indicated by the detection value of the atmospheric pressure sensor decreases. For this reason, it is determined whether or not the rise has started by determining whether or not the atmospheric pressure has decreased.

  Returning to FIG. 5, when it is determined in step S <b> 111 that the user has started to rise by walking (when it is determined YES), in step S <b> 112, the control unit 110 turns on the rising flag indicating that the user is rising. Put it in a state. The rising flag is stored in the memory 120.

  When it is determined in step S111 that the user has not started ascending by walking (when NO is determined), and after step S112, in step S113, the control unit 110 ends the ascending by walking. Determine whether or not. The determination as to whether or not the increase has ended can be made in the same manner as the determination as to whether or not the increase has started.

  When it is determined that the user has finished climbing while walking (when YES is determined in step S113), the control unit 110 turns off the rising flag in the memory 120 in step S114.

  Next, in step S115, the control unit 110 determines the number of steps m obtained by subtracting the total number of steps when it is determined that the start of the previous rise from the total number of steps when it is determined that the increase has ended this time. It is determined whether or not the number of steps m from the start of the climb to the end of the climb this time is 0.8 times or more the number of steps N (for example, 13 steps) corresponding to the first floor.

  When it is determined that it is not 0.8 times or more (when NO is determined in step S115), in step S116, the control unit 110 has started increasing the number of steps from the accumulated number of steps when it is determined that the increase has ended this time. Whether or not the number of steps n obtained by subtracting the accumulated number of steps at the time of determination, that is, the number of steps n from the start of the previous rise to the end of the current rise is 0.8 times or more of the first floor stage number N Judging.

  When it is determined that the number of steps m from the previous time to this time is 0.8N or more (when it is determined YES at step S115), and when the number of steps n from the previous time to this time is determined to be 0.8N or more (YES at step S116). In step S117, the control unit 110 adds 1 ascending floor number, which is the floor number raised by the user. The rising floor number is stored in the memory 120.

  When it is determined that the user has not finished walking up (when NO is determined at step S113), when the number of steps n from the previous time to this time is determined to be less than 0.8N (when NO is determined at step S116) ), And after step S117, the control unit 110 returns the process to be executed to the body motion detection display process that is the caller of the increase detection addition process.

  In the staircase, not only at the landing for each floor, but also at the landing in the middle of the floor (for example, in the middle of the floor), it is determined at step S111 that the ascent has started, and at step S113, It is judged that the climb has ended. Therefore, in the processing from step S113 to step S117, when it is determined that the ascent has ended, if it can be determined that the number of steps from the previous time to the current time has reached the number of steps of one floor, If it is determined that the staircase without landings has risen by almost one floor and the number of rising floors is incremented by 1, while it can be determined that the number of steps from the previous time to this time has reached the number of steps for one floor, The staircase with a landing on the way is judged to have risen by almost one floor, and the number of rising floors is incremented by one.

  For this reason, it is determined whether or not the step difference m, n is 0.8 times or more of the number of steps N for the first floor, but is not limited to 0.8, and it is determined that the number of steps for the first floor has been reached. Any other magnification may be used as long as it is possible.

  Also, the number of stages N on the first floor is, for example, 13 stages, but in the case of a detached house, it is often about 13 stages, and in the case of an office building or apartment, it is 13 stages or more. Since there are many cases, the first floor stage number N may be another value. Further, it may be configured such that the user can set the number of steps N for the first floor according to the number of steps used normally.

  In addition, the time when it started rising last time is the time when the rising of the stairs for the first floor without a landing was started. For this reason, the number of steps obtained by subtracting the total number of steps at the start of the previous increase from the total number of steps at the time when it is determined that the increase has ended is extremely large (for example, more than twice the first floor division number N). ), The staircase that was previously determined to have started rising may be different from the staircase that has been determined to have ended rising this time, so in such a case, the number of rising floors is not incremented by one. You may do it.

  Similarly, the time when the ascent is started two times before is when the ascent of the first floor where the landing is located starts. For this reason, the number of steps obtained by subtracting the total number of steps at the start of the previous increase from the total number of steps at the time when it is determined that the increase has ended is extremely large (for example, more than twice the number of floors N on the first floor). )), The stairs that have been determined to have started rising may be different from the stairs that have been determined to have finished rising this time. In such cases, the number of rising floors is not incremented by one. You may do it.

  Returning to FIG. 4, after executing the rise detection addition process in step S <b> 110, in step S <b> 120, the control unit 110 executes the drop detection addition process. This descending detection addition process is a process in which “rise” is replaced with “fall” in the rise detection addition process described with reference to FIG.

  Next, in step S <b> 130, the control unit 110 executes automatic elevation detection addition processing. FIG. 6 is a flowchart showing a flow of automatic lifting detection addition processing executed by the activity meter 100 according to the first embodiment.

  With reference to FIG. 6, in step S <b> 131, control unit 110 determines whether or not there has been a change in the tendency of fluctuation of the detection value indicated by the detection signal from acceleration sensor 170. Specifically, when the user starts or ends the elevating and lowering of stairs and slopes as described in step S111 of FIG. 5 described above, the user starts and ends the elevating and lowering using elevators and escalators. In this case, some change occurs in the tendency of fluctuation of the detection value of the acceleration sensor 170.

  If it is determined that there has been a change in the trend of fluctuation in the detected acceleration value (YES in step S131), in step S132, the control unit 110 reads the detection value indicated by the detection signal from the barometric sensor 180. And stored in the memory 120.

  Next, in step S133, the control unit 110 determines the accumulated step count when it has been determined that there has been a change in the acceleration variation trend last time from the accumulated step count when it has been determined that the acceleration variation trend has changed. , That is, the number of steps m from the previous change in acceleration fluctuation to the current change in acceleration fluctuation is the number of steps N ( For example, it is determined whether or not it is less than 0.8 times (13 steps).

  If it is determined that the number of steps m from the previous time to this time is less than 0.8 times the first floor stage number N (YES in step S133), in step S134, the control unit 110 determines that the acceleration fluctuation The pressure difference d obtained by subtracting the detected value of atmospheric pressure when it was determined that there was a change in the trend of acceleration last time from the detected value of atmospheric pressure when it was determined that there was a change in trend. The absolute value of the pressure difference d from the change in the trend until the change in the trend of the acceleration is 0.8 times the pressure difference P (for example, 0.3 hPa) corresponding to the first floor. Judge whether there is.

  When it is determined that the absolute value | d | of the pressure difference between the previous time and the current time is 0.8 times or more of the pressure difference P of the first floor (when determined YES in step S134), in step S135, the control unit 110 It is determined whether or not the pressure difference d between the previous time and the current time is greater than 0, that is, whether or not the pressure difference d is positive.

  If it is determined that the pressure difference d is positive (YES in step S136), in step S136, the control unit 110 divides the pressure difference d between the previous time and this time by the pressure difference P for the first floor and rounds off. This is added to the automatic descending floor number, which is the sum of the descending floors using the lifting device. The automatic descending floor number is stored in the memory 120.

  On the other hand, when it is determined that the atmospheric pressure difference d is not positive (when NO is determined in step S137), in step S137, the control unit 110 divides the atmospheric pressure difference d between the previous time and the current time by the first floor atmospheric pressure difference P. The value obtained by reversing the positive and negative values and rounding them up is added to the automatic ascending floor number, which is the sum of the floor floors raised using the lifting device. The automatically raised floor number is stored in the memory 120.

  When it is determined that there is no change in the acceleration fluctuation trend (when NO is determined in step S131), when it is determined that the number of steps m from the previous time to this time is not less than 0.8 times the number N of first floor stages (step S133). Step NO), if it is determined that the absolute value | d | of the atmospheric pressure difference between the previous time and this time is not more than 0.8 times the atmospheric pressure difference P of the first floor (if NO is determined in step S134), step After S136 and after step S137, control unit 110 returns the process to be executed to the body motion detection display process that is the caller of this automatic lift detection addition process.

  In this way, the change in the tendency of acceleration fluctuations shows when you think you got on the lifting device and when you think you got off, and the total number of steps when you think you got on the lifting device and the number of steps you think you got down Although the difference in the number of steps seems to have not reached the first floor stage number N, the pressure difference between when it seems to have got on the lifting device and when it seems to have got off has reached almost the first floor pressure difference P. When it can be determined that the user has moved up and down using the lifting device, the pressure difference d is calculated by dividing the pressure difference d by the pressure difference P for the first floor. If it rises to the floor, it will be added to the automatically raised floor.

  For this reason, it is determined whether the pressure difference d and the step difference m are 0.8 times or more the first-floor pressure difference P and the first-floor stage number N, respectively, but is not limited to 0.8. Any other magnification may be used as long as it can be determined that the number of steps of the first floor has been reached.

  Also, assuming that the floor height is 3 meters, which is about the first floor of a detached house, the pressure difference P for the first floor is 0.3 hPa. However, the present invention is not limited to this, and it is assumed that it is 5 meters for the first floor of an office building and 4 meters for the first floor of an apartment, and the atmospheric pressure difference P for the first floor is 0.5 hPa and 0.4 hPa, respectively. It is good as well. Further, the first-floor pressure difference P may be another value. Moreover, you may comprise so that a user can set the atmospheric | air pressure difference P for 1st floor by himself / herself according to the floor height of the building normally used. It is assumed that the atmospheric pressure decreases by 0.1 hPa every time the altitude increases by 1 meter.

  Returning to FIG. 4, after step S <b> 130, in step S <b> 171, the control unit 110 determines whether walking or running for one step has been detected based on the detection value from the acceleration sensor 170. As a technique for detecting the number of steps from the detected acceleration value, a conventional technique can be used.

  If it is determined that one step has been detected (YES in step S171), in step S172, control unit 110 adds one step to the accumulated number of steps. The accumulated number of steps is stored in the memory 120.

  Further, in step S173, control unit 110 determines whether or not the rising flag is turned on in step S112 of FIG. 5 described above. When it is determined that the rising flag is in the on state (when YES is determined in step S173), in step S174, the control unit 110 calculates an ascending step count that is an accumulated step count when the user ascends the stairs or the hill. Add one step. The ascending step count is stored in the memory 120.

  On the other hand, when it is determined that the rising flag is not in the on state (when NO is determined in step S173), in step S175, the control unit 110 determines whether the lowering flag is turned on in the decrease detection addition process in step S120. Judge whether or not. When it is determined that the descending flag is on (when YES is determined in step S175), in step S176, the control unit 110 calculates a descending step count that is an accumulated step count when the user descends the stairs or the hill. Add one step. The descending step count is stored in the memory 120.

  In this way, the number of steps according to the exercise mode such as whether the user is walking on the flat ground, rising or falling can be counted. In this case, the exercise form is any one of the flat ground walking, the ascending walking, and the descending walking. However, the present invention is not limited to this, and the exercise form includes the flat ground traveling, the ascending traveling, the descending traveling, and the like. Other motion forms may be included.

  If it is determined that one step has not been detected (NO in step S171), after step S174 and after step S176, in step S181, control unit 110 performs step S117 in FIG. The above described rising floor and the automatic rising floor described in step S137 of FIG. 6 are being displayed, or the display change / decision switch 131 of the operation unit 130 is operated to display the rising floor and the automatic rising floor. It is determined whether or not an operation for switching has been performed.

  When it is determined that the rising floor and the automatic rising floor are being displayed or the display has been switched to the display of the rising floor and the automatic rising floor (when YES is determined in step S181), in step S182, the control unit 110 5 is read from the memory 120, and the number of rising floors stored in the memory 120 and the number of automatic rising floors counted in the step S137 of FIG. A control signal is transmitted to the display unit 140 so as to be displayed.

  FIG. 8 is a first display example displayed on the activity meter 100 according to the first embodiment.

In the above-described embodiment, as described with reference to FIG. 5, it is determined whether or not the user has started or ended lifting / lowering based on the detection value of the acceleration sensor 170, and it is determined that lifting / lowering has been started last time. From this time, when it is determined that the elevator has been lifted this time, if it can be determined that the number of steps for the first floor has been reached, it is determined that the staircase that has no landing in the middle of the floor has risen by about one floor. When it is determined that the ascending / descending operation has been completed, and it has been determined that the ascending / descending operation has been completed this time, it is determined that the number of steps has been reached. Judging that the staircase with a landing in the middle of the road has risen by almost one floor, the number of rising floors is incremented by one.

  FIG. 12 is a graph for explaining the detection of elevation using the gyro sensor in the modification of the first embodiment. Referring to FIG. 12, when a gyro sensor is used, a change in angular velocity about the vertical direction is recognized during a turn at a landing.

  For this reason, when a change is recognized in the detection value of the gyro sensor, it is determined that the user has started or ended the elevating and lowering of the stairs. When it can be determined that it has reached the number of steps of about one floor, it is determined that the staircase without a landing in the middle of the floor has risen by about one floor, and the rising number of floors is incremented by one, If it can be determined that the number of steps has been reached for the first floor when it is determined that the lifting has been completed this time after it has been determined that the lifting has started, the staircase with a landing in the middle of the floor, It may be determined that the floor has risen by almost one floor, and the number of floors to be raised may be incremented by one.

  That is, the user's rising rank may be calculated based on the number of times the user has performed a turn motion calculated based on the detection value from the gyro sensor.

[Second Embodiment]
In the first embodiment, as described with reference to FIG. 5, when it is detected that the vehicle is moving up and down, the ascending / descending floor number is calculated based on the detected acceleration value from the acceleration sensor 170. In the second embodiment, when it is detected that the vehicle is moving up and down, the floor number is calculated based on the detected value of the atmospheric pressure from the atmospheric pressure sensor 180.

  In the first embodiment, as described with reference to FIG. 4, the number of elevation floors when the elevator device is not used and when it is used is displayed. In the second embodiment, the number of times that the lifting device is not used and the number of times that it is used is displayed for every lifting or lowering floor.

  FIG. 13 is a flowchart showing the flow of the body movement detection display process executed by the activity meter in the second embodiment. Referring to FIG. 13, the processing from step S101, step S171 to step S176, and from step S185 to step S188 is the same as the body motion detection display processing of FIG. 4, and therefore, repeated description will not be repeated.

  After step S101, in step S150, the control unit 110 executes a lift detection addition process. FIG. 14 is a flowchart showing the flow of the elevation detection addition process executed by the activity meter in the second embodiment.

  Referring to FIG. 14, in step S <b> 151, control unit 110 determines whether or not there is a change in the tendency of fluctuation of the detection value indicated by the detection signal from acceleration sensor 170. This process is the same as the process in step S131 of FIG.

  When it is determined that there is a change in the tendency of fluctuation in the detected acceleration value (when YES is determined in step S151), in step S152, the control unit 110 causes the user to increase or decrease during walking such as stairs and hills. Determine if it has started. This process is the same as the process of step S111 in FIG.

  When it is determined that the user has started to rise or descend by walking (when YES is determined in step S152), in step S153, control unit 110 turns on the rising flag or the falling flag, respectively. This process is the same as the process of step S112 in FIG.

  When it is determined that the user has not started ascending or descending by walking (when NO is determined in step S152), and after step S153, in step S154, the control unit 110 determines whether the user has increased or decreased by walking. It is determined whether or not the descent is finished. This process is the same as the process in step S113 of FIG.

  When it is determined that the user has finished climbing or descending while walking (when YES is determined in step S154), in step S155, control unit 110 turns off the rising flag or the falling flag, respectively. This process is the same as the process in step S114 of FIG.

  When it is determined that the user has not finished walking up or down (when NO is determined in step S154 and after step S155, in step S156, the control unit 110 detects the detection signal from the atmospheric pressure sensor 180. Is read and stored in the memory 120. This process is the same as the process in step S132 of FIG.

  Next, in step S157, the control unit 110 determines that there has been a change in the trend of acceleration variation last time from the detected value of the atmospheric pressure when it is determined that there has been a change in acceleration variation trend. The atmospheric pressure difference d obtained by subtracting the detected atmospheric pressure value, that is, the absolute value of the atmospheric pressure difference d from the last time the change in the acceleration fluctuation to the current change in the acceleration fluctuation tendency is the first floor. It is determined whether or not the pressure difference P corresponding to the minute is 0.8 times or more. This process is the same as the process in step S134 of FIG.

  When it is determined that the absolute value | d | of the pressure difference between the previous time and the current time is 0.8 times or more of the pressure difference P of the first floor (when determined YES in step S157), in step S158, the control unit 110 It is determined whether or not the pressure difference d between the previous time and the current time is greater than 0, that is, whether or not the pressure difference d is positive. This process is the same as step 135 in FIG.

  When it is determined that the pressure difference d is not positive (when NO is determined in step S158), in step S161, the control unit 110 determines from the accumulated number of steps when it is determined that there is a change in the tendency of acceleration variation this time. The number of steps m minus the accumulated number of steps when it was determined that there was a change in the acceleration fluctuation last time, that is, the change in the acceleration fluctuation trend from the previous time, It is determined whether the number of steps m up to a certain point is 0.8 times or more the number of steps N corresponding to the first floor.

  When it is determined that the number of steps m from the previous time to this time is 0.8 times or more of the first floor stage number N (when determined YES in step S161), it is considered that the number of steps m has increased due to walking. 110 adds 1 to the number of times of ascending stairs used for each number of floors obtained by dividing the pressure difference d between the previous time and the current time by dividing the pressure difference P by the first floor and rounding off. The number of times of ascending stairs used for each floor is the number of times the stairs are used for each number of floors that have risen in one ascending stairs. The number of times of upstairs used for each floor is stored in the memory 120.

  On the other hand, if it is determined that the number m of steps from the previous time to this time is not more than 0.8 times the number N of steps on the first floor (when NO is determined in step S161), it is considered that the number of steps m has increased using the lifting device. In S163, the control unit 110 adds 1 to the number of times of uphill vehicle use for each number of floors obtained by dividing the pressure difference d between the previous time and this time by the pressure difference P for the first floor and rounding off. The number of times of use of the ascending vehicle for each floor is the number of times that the lifting device is used for each floor that has risen in the lift using one lifting device. The number of times of ascending vehicle use for each floor is stored in the memory 120.

  When it is determined that the pressure difference d is positive (when YES is determined in step S158), in step S164, the control unit 110 determines from the accumulated number of steps when it is determined that there is a change in the tendency of acceleration fluctuation this time. , The number of steps m minus the accumulated number of steps when it was determined that there was a change in the acceleration fluctuation trend last time, that is, the change in the acceleration fluctuation trend last time, then this time the acceleration fluctuation tendency changed It is determined whether or not the number of steps m until there is 0.8 or more times the number of steps N corresponding to the first floor.

  If it is determined that the number of steps m from the previous time to this time is 0.8 times or more of the first floor stage number N (YES in step S164), it is considered that the number of steps m has increased due to walking. In step S165, the control unit 110 adds 1 to the number of times of descending stairs used for each number of floors obtained by dividing the pressure difference d between the previous time and the current time by the pressure difference P for the first floor, reversing the sign and rounding off. The number of times of descending staircase use for each floor is the number of times the staircase is used for each floor that descends in one descent of the staircase. The number of times of downstairs used for each floor is stored in the memory 120.

  On the other hand, if it is determined that the number of steps m from the previous time to this time is not 0.8 times or more than the number N of steps on the first floor (when NO is determined in step S164), it is considered that the number of steps m has increased using the lifting device. In S166, the control unit 110 adds 1 to the number of times of use of the descending vehicle for each number of floors obtained by dividing the pressure difference d between the previous time and the current time by the pressure difference P for the first floor, reversing the positive / negative and rounding off. The number of times of use of the descending vehicle for each floor is the number of times of using the lifting device for each floor that has been lowered in the descending using one lifting device. The number of descending vehicle usages for each floor is stored in the memory 120.

  If it is determined that there is no change in the trend of acceleration fluctuation (when NO is determined in step S151), the absolute value | d | of the atmospheric pressure difference between the previous time and the current time is not 0.8 times or more than the atmospheric pressure difference P for the first floor. (When it is determined NO in step S157), after step S162, after step S163, after step S165, and after step S166, the control unit 110 performs the processing to be executed by the up / down detection addition. Return to the body motion detection display process of the caller of the process.

  In this way, it can be seen when the lifting / lowering starts or ends due to the change in the acceleration fluctuation tendency, and the atmospheric pressure difference d when the lifting / lowering is considered to start and when the lifting / lowering is considered to be almost equal to the first floor. When it can be determined that the partial pressure difference P has been reached, if it is considered that the change in the number of steps during that time has reached the number N of steps on the first floor, If the number of steps used for descending stairs is incremented by 1 and the change in the number of steps during that period does not reach the number N of steps for the first floor, the number of times of ascending or descending vehicles used per number of floors, depending on the number of raised and lowered floors 1 is added.

  Here, since the determination in step S161 and step S164 is a determination as to which direction the walking or lifting device is lifted, it may be a value smaller than 0.8 times the number N of first floor stages. . However, since the user may walk several steps while riding on the lifting device, the value is preferably equal to or greater than the number of steps while riding on the lifting device.
