In S _< b _> 7, the main body control unit 12 calculates the average of the total work rate in a specific period (d _{i = 1 to 11} ) that goes back a plurality of specified times from the current (latest). Specifically, the main body control unit 12 calculates the sum of the overall work rate for each specific period d _i, the sum of the overall work rate is divided by the specific time period d _i, calculates a plurality of average work rate . Then, the main body control unit 12 stores the calculated values P _{i = 1} to ₁₁ of each average power in the main body information storage unit 13 in association with the specific period d _i . In the present embodiment, the designated time is 1 second (i = 1), 3 seconds (i = 2), 5 seconds (i = 3), 15 seconds (i = 4), 30 seconds (i = 5). ) 1 minute (i = 6), 3 minutes (i = 7), 5 minutes (i = 8), 10 minutes (i = 9), 20 minutes (i = 10) and 30 minutes (i = 11) Is set. The main body control unit 12 sets the average power for the specific period to “0” when the counter value of the timer counter for average power is less than the predetermined specific period.

In S8, the main body control unit 12 obtains a calculated value time graph indicating the relationship between the specific period d _i and the calculated average work ratio P _i based on the average work rate for the plurality of specific periods calculated in S7. It displays on the display part 15 (refer FIG. 12). Here, as a display method of this graph, for example, as shown in FIG. 12, the vertical axis (Y axis) is an average power P [W], and the horizontal axis (X axis) is a logarithm of a specific period d [second]. and on coordinates, plotting the calculated value P _i of the average work rate for a plurality of specified period d _i, connecting the X _{i = 1 to 11} points plotted with a straight line.

In S9, the main body control unit 12 substitutes the plurality of average power calculated values P _i calculated in S8 into the reference value time relational expression of average power, and calculates these calculated values in the reference value time relational expression. A specific period d _{ref — i} for P _i is calculated, and a difference r _i (hereinafter referred to as “specific period difference r _i ”) for the same average power is calculated (see FIG. 11). Specifically, the main body control unit 12 assigns the calculated average power P _i to the next number (2) obtained by modifying the reference value time relational expression, and calculates the average power calculation value of the reference value time related expression. A specific period d _{ref_i} for P _i is calculated, and a specific period difference r _i is calculated by subtracting the specific period d _i related to the specified period from the specific period d _{ref_i} related to the reference value time relational expression.

[Equation 2]
d _ref — _i = AWC / (P _i −CP)

In S10, the main body control unit 12 specifically displays the smallest one of the specific period differences r _i calculated in S9 (hereinafter referred to as “minimum difference”) in a predetermined area of the information display unit 15 (see FIG. 5). (See FIG. 12). Further, the main body control unit 12 illustrates the minimum difference on the information display unit 15. Specifically, the vector is displayed from the point relating to the minimum difference in the calculated value time graph to the point extending horizontally to the reference value time graph (see FIG. 12).

  In S11, the main body control unit 12 determines whether or not the minimum difference is equal to or less than a preset threshold value. If the main body control unit 12 determines that the minimum difference is not less than or equal to the threshold value, the process proceeds to S13. If the main body control unit 12 determines that the minimum difference is equal to or less than the threshold value, the main body control unit 12 performs warning notification using the warning notification unit 16 in S12. Move.

  In step S13, the main body control unit 12 determines whether a predetermined measurement end operation has been performed. When determining that there is no predetermined measurement end operation, the main body control unit 12 moves the process to S3, and when determining that the predetermined measurement end operation is performed, the main body control unit 12 ends the main process.

  Next, display of the average power, the average power difference, and the average power difference will be described with reference to FIGS. The graph in the upper diagram of FIG. 10 is a graph showing the relationship between the power and the elapsed time in which the vertical axis indicates the power P (W) and the horizontal axis indicates the elapsed time t (min). Here, the total of the total work rate in a specific period that goes back a plurality of specified times from the elapsed time that is a predetermined reference (“current time (latest time)” in the present embodiment) is calculated, and these totals are supported. The value divided by the specific period is the average work rate for the specific period. In the present embodiment, 1 sec, 3 sec, 5 sec, 15 sec, 30 sec, 1 min, 3 min, 5 min, 10 min, 20 min, and 30 min are set as the specific period. On the coordinates where the vertical axis (Y axis) is the average power P [W] and the horizontal axis (X axis) is the logarithm of the specific period d [t], the calculated value of the average power for the specific period is plotted, A graph obtained by connecting the plots with a straight line is a calculated value time graph (the lower diagram in FIG. 10).

Next, the specific period difference r _i will be described with reference to FIG. In FIG. 11, the vertical axis (Y-axis) is an average power P (W) and the horizontal axis (X-axis) is a logarithmic display of a specific period d (t). The left graph represents the calculated value time graph, and the right graph represents the reference value time graph. The specific period d that is the X-axis component of the intersection of the straight line extending horizontally from the calculated value P _i (X _i ) of the average power for the specific period d _i related to the specified time on the calculated value time graph and the reference value time graph The distance to _{ref_i} is the specific period difference r _i .

In the examples of FIGS. 11 and 12, the calculated value time graph is on the left side of the reference value time graph, and it is shown that the driver is currently traveling at a pace lower than the optimum pace. Further, the specific period difference r ₃ with respect to the specific period d ₃ (= 5 s) is the smallest. In other words, the current optimum pace distribution is to continue the specific period difference r ₃ running while maintaining the pace of the average work rate P ₃ , in other words, to run so that the calculated value time graph approaches the reference value time graph. It represents something.

  In this way, the average work rate over a plurality of specific periods is calculated and displayed, so by using the average work rate as an index for training and cycling exercises, the driver can run with an optimal pace distribution according to the current situation. In addition, effective and appropriate training can be performed. Furthermore, since the reference for the specific period is the current time, an index such as training becomes accurate. In addition, since the relational expression between the reference value of the average work rate and the specific period is calculated and displayed, it is possible to run with a more optimal pace distribution and perform effective and appropriate training. Further, since the relational expression between the reference value of the average work rate and the specific period is unique to the driver, training and the like are more effective and appropriate. Furthermore, since the specific period difference is calculated and displayed, the optimum pace distribution can be easily understood.

  If the calculated value time graph is on the right side of the reference value time graph and the driver is currently driving at a pace exceeding the optimum pace, the calculated value time graph should be brought closer to the reference value time graph. It is shown that it is the optimum pace distribution to run with the pace reduced to the next. According to the idea, if the current overpace is reasonable for the driver, the current pace can be maintained and the reference value can be updated. In this way, training is performed by using the relationship between the calculated average work rate and the reference value (average work rate calculated value time graph and reference value time graph) for a plurality of specific periods as an indicator during running (exercise). Etc.

In the examples of FIGS. 11 and 12, the minimum difference is specifically displayed as a number, but the display content is not limited to this, and the calculated average power P _i and the reference value P for the same specific period are not limited thereto. Other information such as the smallest difference from _ref can be displayed. The display content is not limited to one and may be plural. This display content can be set in advance. Further, for example, in the information input process of S1 of the main process, it is possible to select by operating the operation units 14a to 14c. In addition, although the relationship between the calculated value of the average work rate and the specific period and the relationship between the reference value and the specific period are displayed in a graph, it is also possible to display them in numbers using a matrix table.

  Moreover, as shown in the example of FIG. 11 and FIG. 12, when running at a pace that is currently less than the optimal pace, and driving the calculated value time graph closer to the reference value time graph so as to become the optimal pace, The countdown display can be made to be the information display unit 15 from a predetermined time before the optimum pace is reached. Thereby, the player can easily recognize the target achievement.

  Further, in the present embodiment, the average of the work rate in the specific period is calculated, but is not limited to the average of the work rate, and as a value representing the specific period, in each specific period such as the mode value and the median value Other summary statistics for expressing the central position of the distribution of calculated values of power can also be calculated.

Further, when the calculated value time graph is on the right side of the reference value time graph and the driver is currently driving at a pace exceeding the optimum pace, the specific period difference r _i is displayed as a specific number “ -XX: XX "can be displayed as a minus sign, and"-"can be displayed as unmeasurable.

  In the present embodiment, when the minimum difference is equal to or smaller than the threshold value, an alert sound is sounded as a warning notification, but the background color of the information display unit 15 or a predetermined character / graph is different from a normal state as a warning notification. It is also possible to change to

Further, in the present embodiment, the reference value time relational expression parameter is input in the information input process of S1 of the main process. For example, the calculated value P _i of the average work rate for each specific period every time the bicycle travels. Can be stored and calculated based on the calculated value P of the past average power. By updating in this way, the training index becomes more accurate.

  In this embodiment, when the counter value of the timer counter for average work rate is less than a predetermined specific period, the average work rate for the specific period is set to “0”. It is also possible to calculate the sum of the average powers of each of the two and to calculate the average power for the specific time period by dividing the value by each specific time period.

  In the present embodiment, the measuring device of the present invention is configured by the cycle computer 100 and applied to a bicycle. However, the measuring device is not limited to this, and can also be applied to a stationary training bicycle or swan boat. It is. Moreover, if it can detect a specific period and an average work rate, it is also possible to apply to swimming, a marathon, etc.

  Further, processing such as calculation of the average power and calculation of the specific period difference is executed based on a program built in the ROM 12b of the main body control unit 12 of the main body 1 of the cycle computer 100, but the program such as a CD is recorded. The recorded recording medium can also be used. The program can be stored in advance in the ROM 12b or downloaded and acquired. It is also possible to make the main body 1 communicable with a predetermined server and execute processing such as calculation of an average work rate and calculation of a specific period difference using a program on the server.
