Description

  The present invention relates to a running pace display control device and a running pace display control method for displaying a running pace.

  In a competition such as a marathon, the total elapsed time from the start point to the measurement point, that is, the elapsed time from the start point to the timing of passing through any point is the split time or running time (hereinafter referred to as “split time”). On the other hand, the time taken between points, such as from 5 km to 10 km, that is, the time taken for traveling in any section or the lap time taken to go around the track A stopwatch device with a function that can measure the split time and lap time with a simple operation, which is called a lap time (the word source is a round time such as a track) or a section time (hereinafter referred to as “lap time”), or A wristwatch type electronic timepiece having such a function is known.

Also, in such a stopwatch device, a function is proposed in which a user inputs a total target time to automatically obtain a target time for each section suitable for the user and display it to the user. (For example, Patent Document 1).
JP-A-9-61558

  Usually, marathon runners express their own and other people's running pace by using unit-distance running times such as “kilo 6 minutes” and “kilo 4 and a half” and taking this pace into account during the race. I often run. Knowing your split time or lap time during a full marathon race will help you check your pace.

  The above running pace can be calculated by dividing the time required to run between two points by the distance traveled between the two points. It is necessary to install a GPS (Global Positioning System) or the like, measure the travel distance between any two points with this positioning module, and divide the travel time between the two points by the measured travel distance.

Furthermore, a sensor storage unit S1 in which a step count detection sensor S for detecting the number of steps of the user is stored is provided.

  The display unit 12 is divided into two upper and lower display areas 12a, 12b and 12c, and two upper left and right display areas 12a and 12b are provided. In the case of the clock mode, as shown in FIG. 2, the year of the year is displayed in the display area 12a, for example, “'07”, the date is displayed in the display area 12b, for example, “6-28” is displayed in the display area 12c. Minutes and seconds, for example, “2:47:18” is displayed.

  Next, the operation of the electronic timepiece 1 having the above configuration will be described.

  FIG. 3 shows a flowchart of the main control process executed by the CPU 10.

In the electronic timepiece 1 of this embodiment, the main control process is started when the power is turned on, and the loop process of steps S1 to S6 is repeatedly executed.
That is, in the loop processing, first, the operation state of the mode switch B3 is read, and the mode information in the mode setting area 14m of the RAM 14 is switched based on this operation state (step S1).
For example, when the mode switch B3 is pressed for a long time and an ON signal is input for a predetermined time or longer, the CPU 10 rewrites the information in the mode setting area 14m of the RAM 14 with information indicating the stride setting mode, and the output of the switch SW3 is If it is in the ON state for a short time, the CPU 10 rewrites the information in the mode setting area 14m of the RAM 14 with information indicating the running pace display control mode, and if the output of the switch SW3 remains off, the mode setting area 14m in the RAM 14 The information is left as it is.

Subsequently, the process branches to the processing routine of each mode according to the mode information stored in the mode setting area 14m of the RAM 14 set as described above (steps S2 and S3).
That is, if the information in the mode setting area 14m of the RAM 14 is in the stride setting mode, the process proceeds to the stride setting routine (FIG. 4) in step S4, and if in the travel pace display control mode, the travel pace display control in step S5. The process proceeds to the operation routine (FIG. 6). If the time mode is set, the process proceeds to a display routine (FIG. 2) such as the time and date in step S6.

  Then, after performing this branched routine (steps S4 to S6), the process returns to step S1 again, and the loop processing of these steps S1 to S6 is repeated. By this main control process, the user can operate the switch B3 to shift to the stride setting mode or the running pace display control mode and execute these processes.

  FIG. 4 shows a flowchart of the stride setting routine executed in step S4 of the main control process, and FIG. 5 shows a front view of a wristwatch showing an example of display contents in the stride setting routine.

The stride setting routine is a process for causing the user to set a stride setting value used for calculation of travel distance estimation described later by the user. The stride setting value is a value representing a stride when the user travels, and is represented, for example, as “500 mm (50 cm)”. The stride setting value input by the key operation of any of the first to fifth switches B1 to B5, for example, 500 mm (50 cm), is stored in the stride setting value area 14b of the RAM 14.
When the routine proceeds to the stride setting routine shown in FIG. 4, first, the stride setting value currently stored in the stride setting value area 14b of the RAM 14 is read, and this read stride setting value is output to the display unit 12 ( Step S11).

  As shown in FIG. 4A, this stride setting value is displayed in the second display area 12b of the display unit 12, for example, “FOOTSTEP 500 mm”. Further, as shown in FIG. 4 (b), “1 km” is displayed in the first display area 12a to indicate that the travel time is 1 km after the step set value is displayed, and the second display area 12b is displayed. A title display such as “PERSONAL PACE” and a unit display such as “/ km” are displayed at the top and bottom of the screen.

  After the display output as described above is performed, next, branch processing is performed according to the input from the operation unit 18 (steps S12 to S15). That is, determination according to the input of the scroll up switch B4 (step S12), determination according to the input of the scroll down switch B5 (step S13), determination according to the input of the mode switch B3 (step S14), or a certain time A determination is made when there is no switch input (step S15).

  If the scroll up switch B4 has been pressed, the process branches to YES in the determination process of step S12, and a process of adding the stride setting value by 1 mm is performed (step S12). When the addition process is completed, the process returns to step S11. Through these processes, the user presses the scroll-up switch B4 intermittently or continuously, so that the stride setting value set in the stride setting value area 14b of the RAM 14 is successively increased. be able to.

  On the other hand, if the scroll down switch B5 has been pressed, the process branches to YES in the determination process in step S13, and a process of subtracting the step length setting value by 1 mm is performed (step S17). Then, after the subtraction process is completed, the process returns to step S11. As a result of such processing, the user presses the scroll down switch B5 intermittently or continuously, so that the stride setting value set in the stride setting value area 14b of the RAM 14 is successively made smaller. I can go.

  Further, if the mode switch B3 has been pressed or no switch operation has been performed for a while and no switch input has been made for a certain period of time, the process branches to step S18 in the discrimination process of steps S14 and S15, and then the clock mode is entered. In order to shift, data indicating the clock mode is written in the mode setting area 14m in the RAM 14 (step S18). Then, this stride length setting routine ends. On the other hand, if any of the determination processes in steps S12 to S15 is NO, the process returns to step S11, and the loop process from step S11 is repeated again.

  By this stride setting routine, the user presses either the scroll up switch B4 or the scroll down switch B5 while looking at the display on the display unit 12, thereby setting the stride setting value necessary for the travel distance estimation in units of 1 mm. It can be changed. When the setting is completed, the third switch B3 is pushed or not left for a certain period of time, and the step setting routine is exited to return to the clock mode.

  FIG. 6 is a flowchart of the running pace display control operation routine executed in step S5 of the main control process (FIG. 3), and FIG. 7 is a front view of a wristwatch as an example of display contents during the running pace display control operation. Indicates.

  The running pace display control function includes (1) a function for measuring the split time, which is the time from the start to the stop, by starting or stopping the time measurement of the measurement time counter 15b by pressing the start / stop switch B1. (2) As will be described in detail later, when the user passes the measurement point where the travel distance is displayed, such as “3 km point” or “7 km point”, for example, the user presses the split lap switch B2. The function of displaying the number of steps at the time when the button is pressed (see FIG. 7), the estimated section distance dd, the total distance d, and the traveling pace of the immediately preceding section as a result of the estimated calculation of the travel distance and the calculation of the travel pace. I have.

  When the routine shifts to the travel pace display control operation routine, first, the display processing of the value of the measurement time counter 15b of the time measuring circuit 15 is performed (step S21). Since the value of the measurement time counter 15b is zero before the start of measurement, “00:00:00” is displayed in the display area 12c. Further, the value of the measurement time counter 15b that is counted up after the start of measurement is displayed.

  After the display process is performed, switch operation input confirmation is performed (steps S22 to S24). That is, pressing the start / stop switch B1, for example, pressing the split / lap switch B2, which is operated by the user when passing the measurement point of the travel distance display such as “3 km point” or “7 km point”, and the mode switch B3 It is determined whether or not is pressed, and if it is determined that these are not pressed, the process returns to step S21 to repeat the loop processing of steps S21 to S24. On the other hand, if any one of the switches B1 to B3 is pressed, branch processing corresponding to them is performed.

  As a result, if it is determined that the start / stop switch B1 has not been pressed, the process branches to YES in the determination process of step S22, and first, it is determined whether or not the running pace display control is currently being measured ( Step S25). If it is determined that the measurement is not being performed, it is recognized that the depression of the switch B1 represents a request to start measurement, and various variables used for the running pace display control function are initialized (step S26). Then, the measurement time counter 15b of the timer circuit 15 is counted up to start measurement (step S27). Then, the process returns to step S21.

  On the other hand, if it is determined in step S25 that the measurement is being performed, it is recognized that pressing of the start / stop switch B1 represents a request for measurement stop. First, the value of the time counter 15b is set as the last lap time in the area of the RAM 14. 14c (step S28), the running pace calculation process from when the previous split / lap switch B2 was pressed is performed (step S29: detailed later), and then the time counter 15b is stopped (step S30). . And it returns to step S21 and displays the counter value at the time of a stop.

  If it is determined in step S23 that the split / lap switch B2 has been pressed in the switch operation determination process, first, the value of the time counter 15b at this time is read and this value is used as the lap time. Is stored in the area 14c (step S31). Then, from this lap time value, the running pace is calculated from when the previous split / lap switch B2 was pressed (step S32: detailed later), and the process returns to step S21.

  Further, in the switch operation determination process in step S24, if it is determined that the mode switch B3 has been pressed, the process exits the loop process of the travel pace display control operation routine and then shifts to the clock mode. Data indicating the clock mode is written in the mode setting area 14m in the RAM 14 (step S33). Then, the running pace display control operation routine is terminated.

  FIG. 8 shows a flowchart of the pace calculation process executed in steps S29 and S32 of the running pace display control operation routine (FIG. 6), and FIG. 9 shows a diagram for explaining the process contents of the pace calculation.

  The pace calculation process is performed when the user presses the split / lap switch B2 after passing the measurement point where the travel distance is displayed, such as “3 km point” or “7 km point”, or at the goal measurement point. This is a process to be shifted when the start / stop switch B1 is pressed.

  When shifting to this pace calculation process, first, the CPU 10 calculates these section times dt from the previous lap time and the current lap time stored in the measurement time area 14c of the RAM 14 (step S41).

Next, the CPU 10 calculates the estimated section distance dd from the step length setting value (STW) set by the user and the step count (STN) detected by the step count detection sensor S (step S42). The stride setting value is a stride setting value input before the start of the start, but indicates an assumed value of the stride while the user is running.First, by multiplying the detected step count and the stride setting value, The section distance when running at the expected stride is calculated.
In the example shown in FIG. 9, for example, at the estimated distance at the 3 km point, the number of steps (STN) detected by the step detection sensor S from the start 0 km point to the 3 km point is 6007 (steps) ”. Since the step setting value STW input before the start is “500 mm”, the number of steps (STN) “6007 (steps)” is multiplied by the step setting value STW “500 mm”. When the value of the multiplication result is divided by 1000 in order to convert the value to the unit of kilometer, “3.0035 (km)” is obtained as the section distance from the start 0 km point to the 3 km point. Further, in the estimated distance at the 7 km point, the number of steps (STN) detected by the step number detection sensor S from the 3 km point to the 7 km point is “8050 (steps)”. Therefore, the number of steps “8050 (steps)”. Is multiplied by the stride setting value STW “500 mm” and divided by 1000 to convert this to kilometer units, and “4.025 (km)” is obtained as the section distance from the 3 km point to the 7 km point. Yes. The same calculation is performed for the estimated distance at the 15 km point, and “8.6000 (km)” is obtained as the section distance from the 7 km point to the 15 km point.

However, since an error may occur between the actual travel distance and the estimated travel distance due to variations in stride during travel, the section distance calculated from the multiplication result should have an error. On the other hand, the timing when this pace calculation process is executed is when the user passes the measurement point of the travel distance display and the split / lap switch B2 is pressed. Therefore, the estimated section distance is a distance that is an integral multiple of the unit distance. Therefore, by performing the process of rounding off the fraction from the value of the multiplication result, the above-mentioned error is removed, and the nearest section distance dd is obtained from the estimated section distance candidates.
For example, in the example of FIG. 9, 3.0035 [km] is changed to 3 [km] at the 3 km point, 4.025 [km] is changed to 4 [km] at the 7 km point, and 8.6000 [km] is set at the 15 km point. A fraction is processed like 9 [km], and the shortest traveling distance is obtained from the integral multiples of the unit distance in the candidate.

When the mileage assumed based on the user's preset stride setting value is not significantly deviated by the fraction processing as described above, the deviation is well removed and the mileage traveled by the user is An estimate can be obtained.
For example, at the measurement point of 3 km and the measurement point of 7 km in FIG. 9, the error is removed, and the estimated travel distance dd that matches the actual travel distance is obtained.
On the other hand, if the assumed running pace based on the user's running pace and the preset stride setting value is greatly deviated, the deviation may not be removed well. For example, at the measurement point of 15 km in FIG. 9, the estimated travel distance dd is shifted by 1 km from the actual travel distance.

  When the section distance dd is calculated, the previous total distance stored in the RAM 14 and the section distance dd are added to calculate a new total distance d (step S43), and the section time dt is estimated. The current travel pace (travel pace of the section) p is calculated by dividing by the section distance dd (step S44).

  Then, the travel distance d calculated in the above step, the actual travel pace p, and the current lap time stored in the RAM 14 are each displayed on the display unit 14 (step S45).

  FIG. 10 shows an example of the display contents output to the display unit 14 and an example of the display when the travel distance is corrected thereafter in the pace calculation process shown in FIG. FIG. 5A shows a display example of a wristwatch output first by the pace calculation process, and FIG. 5B shows a display example of the wristwatch when the down switch is pressed.

  FIG. 10A shows a display example at a passing point of 3 km. As shown in FIG. 10, the estimated total distance d “DISTANCE 16 km” is displayed in the first display area 12 a by the display output process of step S45. However, the travel pace p “PACE 4: 59 / km” calculated based on the estimated section distance dd is displayed in the second display area 12b, and the section time dt “SPLIT 1:21:35” is displayed in the third display area 12c. Are displayed and output. The user can check his / her own running pace immediately before the split / lap switch B2 is operated by looking at the display of the running pace p “4: 59 / km”.

  Once the display process is performed, a loop process for determining switch input is performed (steps S46, S48, and S50). That is, it is determined whether the distance up switch B4 or the distance down switch B5 is pressed or which switch B4, B5 is not operated for a certain time (for example, 10 seconds). If no condition occurs, the switch input loop process (steps S46, S48, S50) is repeated.

  Here, when the distance up switch B4 and the distance down switch B5 are pressed, if there is a deviation between the estimated travel distance in step S42, the user looks at the travel distance display and corrects it accordingly. Is to be done. As described above, in the calculation processing of the estimated section distance dd, there may be a deviation from the estimated distance. For example, in the example of the measurement point of 15 km in FIG. 9, the estimated distance is “16 km”. Therefore, when compared with the actual travel distance that the user actually passes through the measurement point, it is estimated to be shifted by 1 km.

  FIG. 11 shows an explanatory diagram of processing contents when the down switch is pressed in the pace calculation processing.

  The user determines the difference between the actual travel distance and the estimated travel distance, the estimated total distance value (dd) displayed in the first display area 12a of the display unit 12, and the measurement on the course. Since it can be recognized immediately by comparing with the actual travel distance display value at the point, when there is such a deviation, the distance up switch B4 or the distance down switch B5 is pressed to correct the estimated travel distance. Do.

Here, the deviation of the estimated traveling distance from the actual traveling distance should be caused by a difference of an integral multiple of 1 km. Therefore, the estimated distance is shifted by 1 km by pressing the distance up switch B4 or the distance down switch B5.
For example, in the example of FIG. 11, when the estimated total distance is “16 km (section distance 9 km)” and the travel distance actually traveled by the user at the measurement point of the travel distance display of 15 km, Since the estimated display (Fig. 10 (a)) is longer than the actual travel distance of 15km (Fig. 10 (a)), the estimated total distance d is set to "15km (section distance 8km)" by pressing the distance down switch B5 once. Correct it. When the estimated total distance d is short, the distance up switch B4 can be pushed in the same manner to correct it by 1 km, and when it is shifted by several km such as 2 km or 3 km, a plurality of switches B4 and B5 are provided. You can fix them by pressing once.

  In the above switch discrimination loop process (steps S46, S48, S50: FIG. 8), if the distance up switch B4 is pressed, the process branches to the yes side of the discrimination process in step S46, and the estimated total distance d and A process of adding “1” to the estimated section distance dd is performed (step S47). Thus, the estimated section distance and the estimated total distance are corrected by adding unit distances.

  When the distance down switch B5 is pressed, the process branches to the YES side in the determination process in step S48, and a process of subtracting “1” from the estimated total distance d and the estimated section distance dd is performed (step S48). Step S47). Thereby, the estimated section distance and the estimated total distance are subtracted and corrected by unit distance.

After the correction process is performed in steps S47 and S49, the process returns to step S44 and the actual running pace p is calculated again. In the subsequent step S45, the corrected total distance d and the running pace p are displayed, and the user can check the correction contents. The transition of the display contents at that time is as shown in FIGS.
That is, the actual total distance d “DISTANCE 15 km” is displayed in the first display area 12a, the previous running pace p “PACE 5: 37 / km” is displayed in the second display area 12b, and the section is displayed in the third display area 12c. The time dt “SPLIT 1:21:35” is displayed and output.

  Then, the value of the estimated section distance becomes the correct section distance value, or is the correct section distance value from the beginning, and is set for a predetermined time without pressing the distance up switch B4 or the distance down switch B5. When (for example, 10 seconds) elapses, the loop process is exited in the determination process of step S50, and the total distance d, the running pace p, and the current lap time obtained by the above calculation process are stored in the RAM 14 (step S51). . And this pace calculation process is complete | finished.

  By such a pace calculation process, when the user passes the measurement point of the travel distance display during the travel pace display control operation, by pressing the split / lap switch B2, as shown in FIG. In addition to the lap time at that time, the total distance and running pace at that point are displayed and displayed to the user. Also, if the estimated total distance is wrong, pressing the distance up switch B4 or the distance down switch B5 corrects the total distance as shown in FIG. The correct running pace after being recalculated based on the distance can be presented to the user.

As described above, according to the electronic timepiece 1 of this embodiment, the user starts counting time by running pace display control operation from the start point in a competition such as a marathon, and thereafter, for each section useful for the competition. Information on the running pace can be acquired with a simple operation.
That is, when the user presses the split / lap switch B2 at the measurement point where the travel distance is displayed on the course, the travel distance and the section distance to that point are automatically estimated, whereby the current travel pace (1 The travel time per kilometer is calculated and displayed. The user can immediately determine from the display of the running pace whether the current running pace is slower or faster than usual or the amount of fluctuation in the running pace during the race. Furthermore, since a positioning system or the like is not used for such a function, an increase in the size and cost of the electronic timepiece 1 can be avoided.

  In addition, the “step length setting value”, which is the basis of the user's assumed running pace value used for mileage estimation, can be set and input by the user. In addition, by setting the stride setting value, it is possible to perform highly accurate travel distance estimation corresponding to various users from users with fast travel pace to users with slow travel pace.

  Also, when estimating the travel distance, the estimated section distance is obtained by multiplying the detected number of steps (STN) by the step length setting value (STW) and rounding off the fraction. The distance can be estimated with a small process.

  In addition, when the estimated travel distance is estimated to deviate from the actual travel distance, the user can easily check the misalignment by looking at the display deviated during that time. It can be corrected by operation. Further, the actual travel pace is automatically recalculated using the corrected travel distance value, so that the user can acquire the correct travel pace information. Further, since the estimated distance is corrected by a method of increasing / decreasing the distance by a unit distance using two switches B4, B5, the user can easily correct the estimated distance even while traveling.

  In the above embodiment, when estimating the distance, 1 km is used as the unit distance, and the distance that is an integral multiple of the unit distance is used as the candidate for the travel distance. For example, 1 mile is used as the unit distance. Distance estimation is performed using a distance that is an integral multiple of the unit distance as a candidate for a travel distance, or distance estimation is performed using a distance that is an integral multiple of this unit distance as a candidate for a travel distance with one round of a 400 m track as a unit distance. You can also do it. Further, such a unit distance may be configured so that the user can selectively switch.

  In the above embodiment, the estimated section distance is calculated using the process of multiplying the number of steps (STN) and the step length setting value (STW). However, the number of steps from the start point and the step length (STW) are multiplied. Then, the total distance from the start may be estimated. In the above embodiment, as the actual running pace, the running pace for each section in which the split / lap switch B2 is pressed is calculated and displayed. However, the running pace passed from the start is calculated and displayed. It can also be done. Further, these may be switched.

  In the above embodiment, the user can set and input the assumed running pace as the “step length setting value”. However, a general running pace value is set in the apparatus in advance, and this value is set. It can also comprise so that distance estimation may be performed using. Further, in the above embodiment, from the start to the end of the travel pace display control, the assumed travel pace is used as a fixed value for distance estimation. For example, a known change pattern in the travel pace from the start to the end of the time measurement is used. If there is, the value of the running pace assumed in accordance with this change pattern may be changed from the set value and used for distance estimation.

  In the above embodiment, the configuration in which the traveling pace display control function is mounted on the wristwatch-type electronic timepiece has been described. However, the present invention can be applied to various forms of the traveling pace display control device. In addition, the detailed configuration and the processing method shown in the embodiment can be appropriately changed without departing from the gist of the invention.
