Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data display device attached to a bicycle.

[0002]

2. Description of the Related Art Running physical quantities such as a running speed and a running distance are detected based on a pulse wave detected according to the rotation of a wheel of a bicycle and a wheel size stored in an internal RAM of a microcomputer. Bicycle speedometers that are configured to display on screen are known. In addition, the bicycle is used not only as a means of transportation but also for training to improve physical strength and competitiveness in various sports.

Since the conventional bicycle speedometer only displays the above-mentioned physical quantity of running, it cannot be said that the training by the bicycle is performed efficiently. For example, as one of the training methods, interval training (training in which rapid running and slow running are alternately repeated for a predetermined time or a predetermined number of times at a predetermined distance) is known. Whether it is a rapid running state or a slow running state, the remaining time, the remaining distance, and the function of notifying the user of the number of sets, etc. is necessary, but in the conventional data display device of the bicycle, No one has such a function.

On the other hand, in a so-called aerobic cycle device which is fixedly used on the floor, for example, a training program having a content of performing high speed traveling for 5 minutes (or 1 km) and then low speed traveling for 10 minutes (or 2 km) is provided. Some have a speedometer that can be advanced according to the passage of time or mileage and can display the progress (remaining time, etc.) on the screen.

Therefore, it is conceivable to use the speedometer used in the aerobic cycle device for a bicycle and efficiently perform the interval training or the like while actually traveling the bicycle.

[0006]

However, when actually traveling on the road by a bicycle, deceleration at a corner,
There are many factors that hinder the progress of a preset program, such as stoppage due to traffic lights and restrictions on traveling speed due to traffic conditions. Therefore, even if the conventional speedometer that advances the training program based on the elapsed time and the traveled distance regardless of whether or not the vehicle is actually traveling at high speed is used for the bicycle as it is, the efficiency of the training cannot be expected. That is, although the bicycle is actually stopped or the set traveling speed has not been reached, the program progresses depending on the passage of time and the traveling distance even though the content of the training program is not yet digested. It will be.

If the speedometer is frequently watched to check the progress of the program,
This is not preferable for improving the concentration of training and safety during training on a bicycle that actually runs on the road.

In view of the above circumstances, the present invention can improve the efficiency of training on a bicycle that actually runs on the road, and can improve the concentration of training and safety during training. An object of the present invention is to provide a data display device for a bicycle.

[0009]

A bicycle data display device of the present invention runs on the basis of a pulse signal from a memory means for holding various setting conditions in a training program and a rotation detection means provided in a rotation system of the bicycle. A means for calculating a physical quantity, a means for advancing the training program based on the travel distance or elapsed time in the traveling physical quantity, a means for displaying the progress status of this program, and a progress of the training program by an interruption operation by the user. It is characterized by having a program interruption means for stopping and for proceeding the training program based on the returning operation.

Further, the bicycle data display device of the present invention calculates the physical quantity of running on the basis of the pulse signal from the memory means for holding various setting conditions in the training program and the rotation detection means provided in the rotation system of the bicycle. Means, the running distance or elapsed time in the running physical quantity and the presence or absence of the pulse signal based on the presence or absence of the pulse signal, stop the progress of the training program, when the pulse signal is detected training It is characterized by having means for advancing the program and means for displaying the progress of the program.

In addition, the bicycle data display device of the present invention calculates the running physical quantity based on the pulse signals from the memory means for holding various setting conditions in the training program and the rotation detecting means provided in the bicycle rotation system. Means, and when the traveling speed does not reach the set speed based on the traveling distance or the elapsed time in the traveling physical quantity and the traveling speed, the progress of the training program is stopped, and when the traveling speed reaches the set speed, the training is performed. It is characterized by having means for advancing the program and means for displaying the progress of the program.

Further, in any one of the above configurations, an informing means for informing the progress of the training program by audible sound or voice may be provided.

[0013]

According to the first configuration, even when the training program is advanced based on the traveling distance or the elapsed time without considering the traveling speed, the user can judge the current traveling speed as the speed set by the program. When it is determined that the training program is not satisfied, or when the vehicle actually runs by inertia without pedaling, the progress of the training program can be stopped by the interruption operation. Then, when the running speed that meets the conditions of the program can be maintained again or when the pedaling operation is restarted, the program can be advanced by the return operation, so the contents of the training program are not fully digested. However, it is possible to solve the problem that the program progresses over time.

According to the second configuration, when the pulse signal is not detected based on the traveling distance or elapsed time and the presence or absence of the pulse signal, the progress of the training program is stopped and the pulse signal is detected. Since the training program proceeds when the bicycle is stopped, the progress of the program is automatically stopped when the bicycle is stopped, and the program proceeds due to the passage of time etc. even when the bicycle is stopped. Such a problem can be solved, and the user does not need to manually stop and restart the program one by one.

According to the third configuration, when the traveling speed does not reach the set speed based on the traveling distance or elapsed time and the traveling speed, the progress of the training program is stopped and the traveling speed reaches the set speed. The training program proceeds when the bicycle is running, so the program will stop automatically when the bicycle speed is less than the set speed. It is possible to solve the problem that the program progresses due to the passage of time and the like, and it becomes unnecessary for the user to manually stop and restart the program one by one.

According to the fourth structure, the progress status of the training program is informed to the user also by an audible sound or voice, so that the user frequently uses the speedometer to confirm the progress status of the program. There is no need to look at it, the concentration of training is improved and the safety during training is improved.

Further, various traveling data are displayed on the lower stage side, and the meaning contents thereof are represented by the abbreviation symbols displayed between the upper stage and the lower stage. Specifically, in the figure (a), the traveling time "TIM" is displayed,
It shows that the vehicle has run for 1 hour and 30 minutes. In addition, in the figure (b), the traveling section distance "DST", in the figure (c), the accumulated traveling distance "ODO", in the figure (d), the average speed "AVS", and in the figure (e). Maximum speed "MXS"
In the same figure (f), it is shown that a clock mark indicating the current time is displayed.

FIG. 3 is also a diagram showing a display example of the liquid crystal display device 14, but this display is made during the execution of the interval training program. The display "TRA" at the upper left of the screen indicates that the program for interval training is being executed, "10" below it indicates the number of remaining sets of interval training, and the English letters consisting of "RUN" or "SLOW" below it respectively. Indicates sudden or slow running. Also, the number "1: 0" displayed at the bottom right of the screen.
"0" and the like indicate the remaining time of the rapid running or the slow running in minutes. In addition, this display example is a display corresponding to the interval training in which one set includes one minute of rapid running and two minutes of slow running, and a total of 10 sets of this are performed. In the figure, (b) shows the end point of the sudden travel, (c) shows the start point of the slow travel, and (d) shows the end point of the slow travel.

The figures (a) to (d) are repeated for the set number of times, and the change of the display contents will be specifically described below in the order of this display example. First, the IN
When the TST / SP button 13 is pressed, the interval training program starts and the buzzer 1
From 7 (shown in FIG. 5), a buzzer sound “beep, blip” is output to notify the user of the start of rapid running and the screen of FIG. The display of "RUN" is made to blink.

When the rapid running state is maintained for 1 minute, the screen shown in FIG. 7B is displayed and the buzzer 17 outputs a buzzer sound "peeping", which allows the user to change from a sudden running to a slow running. Encourage them to move. After that, the screen at the start of slow running shown in FIG. The "SLOW" display on this screen does not blink. This allows
The difference between the "RUN" display and the "SLOW" display can be easily recognized. Further, if the slow running state is maintained for 2 minutes, the screen shown in FIG. 7D is displayed, and the buzzer 17 outputs a buzzer sound, "pip, pip", to prompt the user to move from the slow run to the fast run. Prompt to. It should be noted that when the set number of times of setting is exhausted, a buzzer sound indicating "end, end, end" is output.

FIG. 4 is a graph showing the content of the interval training in terms of the running time (or running distance) and running speed. The horizontal axis represents the traveling time (or the traveling distance), and the vertical axis represents the traveling speed. After the warm-up period of 30 minutes, 10 sets of 1 minute of rapid running period and 2 minutes of slow running period were performed, and then 30
There is a cool-down period of minutes. Although the display example of FIG. 3 does not show the warm-up period and the cool-down period, the same display can inform the user of these periods.

FIG. 5 is a block diagram showing the circuit configuration of the bicycle data display device 10. Further, FIG. 6 shows the contents of various data stored in the internal RAM of the microcomputer 22.

In FIG. 5, the power supply circuit 19 drives the microcomputer 22, the liquid crystal display unit 14 and the like, and is composed of a lithium battery or the like. The crystal oscillator circuit 18 outputs the operation cycle clock of the microcomputer 22. Microcomputer 22
Calculates the traveling distance and the traveling speed based on the wheel size data and the pulse signal from the wheel rotation speed sensor 15, and also performs various controls in response to commands from button operations in the various operation button groups 20.

The operation contents of the microcomputer 22 will be described below with reference to the flowcharts of FIGS. 7 to 15.

When a lithium battery is mounted on the bicycle data display device 10, the operation starts and various data stored in the internal RAM of the microcomputer 22 is cleared by initialization (step 1). Next, the microcomputer 22 sets the liquid crystal display device 14
All the displayed characters and symbols are turned on (step 2) to enter the setting input state. In this state, the user presses the mode button 11
By pressing, the speed unit (km / h, mile /
h) is selected (step 3), tire circumference is set (step 4), time is set (step 5), and interval training stop mode is selected (step 5a). Then, these data are stored in the internal RAM.

As the interval training stop mode, there are prepared three modes, that is, a manual mode, an auto 1 mode and an auto 2 mode.

The manual mode is a mode in which the interval training program is started / stopped by a manual operation, and is executed from the continuation of the remaining time after the temporary stop for both the rapid running and the slow running. This mode is a mode in which the training program is advanced only by the mileage or the elapsed time. In this embodiment, since the pulse input determination is performed for the auto mode, this pulse input determination is used, and if the program remains stopped even if the pulse input state continues for 30 seconds or more, the buzzer 17 is activated. I make an alarm sound.

The auto 1 mode is a mode in which it is determined that the interval training program has not been exhausted when the wheels are stopped rotating, and that the interval training program has been exhausted when the wheels are rotating. That is, this mode is a mode in which the progress of the program is judged based on the traveling distance or elapsed time and the presence or absence of the pulse signal from the wheel rotation speed sensor 15. Further, in this case, both the sudden running and the slow running are executed from the continuation of the remaining time after the temporary stop.

The auto 2 mode is similar to the auto 1 mode in that the distance traveled or the elapsed time and the wheel speed sensor 15 are set.
This is a mode in which the progress of the program is judged based on the presence or absence of a pulse signal from, but when the wheel stop time in the sudden running state exceeds a predetermined time, the rapid running state is restarted again. . In this embodiment, the temporary stop time is set to ⅕ of the rapid travel set time.

Returning to the explanation of the flow chart again, it is judged whether or not there is a pulse signal input from the sensor 15 (step 6), and if there is no pulse signal input, the process proceeds to step 14, while if there is a pulse signal input, the accumulated running distance is reached. Calculation of (ODO) (step 7) and calculation of traveling speed (SPD) (step 8) are performed. Then, it is determined whether or not the value of the traveling speed (SPD) is larger than the value of the maximum speed (MXS) stored in the internal RAM of the microcomputer (step 9). If it is larger, the SPD value is adopted as the MXS value (step 10) and stored in the internal RAM. Further, SPD and ODO display are performed on the liquid crystal display unit 14 (step 11).

Then, it is judged whether or not the measurement is in progress (steps 12 and 15). If the measurement is in progress, the traveling section distance (DS
T) is calculated (step 13) and the traveling time (TIM) is calculated based on the time count value (step 14) (step 16).

Next, it is judged whether or not the interval training stop mode is the manual mode (step 1
6a), if it is the manual mode, it is judged whether or not interval training measurement is being performed (step 16b), and YE
If S, proceed to step 18. On the other hand, if NO, it is determined whether or not there is a pulse input (step 16c).
If there is no pulse input, the process of MT = 0 is performed (step 16h), and the process proceeds to step 57. Note that MT indicates how many seconds have passed since the start of rotation of the wheels.

If there is a pulse input in step 16c, IN
It is determined whether TST = 1 (step 16d). Note that INTST is a flag indicating whether or not interval training has started. If NO in step 16d, the process proceeds to step 57. On the other hand, YES
If so, the MT is counted up (step 16).
e). Then, it is determined whether MT ≧ 30 seconds (step 16f). If NO, the process proceeds to step 57. If YES, the buzzer sounds "beep, beep, ... (8 times)", requests the user to restart the program (press the INTST / SP button 13), and proceeds to step 57.

If the manual mode is not set in step 16a, it is determined whether INTST = 1 or not (step 16d). If NO, the process proceeds to step 57. YE
If S, it is determined whether or not the stop mode is the auto 1 mode (step 16i). In the auto 1 mode, it is determined whether or not a pulse is input (step 16j), and if a pulse is input, the process proceeds to step 18. If there is no pulse input, the process proceeds to step 57. If it is determined in step 16i that the stop mode is not the auto 1 mode, it is determined whether or not there is a pulse input (step 16k), and if there is a pulse input, the process proceeds to step 18. If there is no pulse input, the AT is counted up (step 16l) and the routine proceeds to step 57. AT is a temporary stop time in the auto 2 mode (time when the wheels are not rotating)
Is shown.

In step 18, it is determined whether the progress of the program is set by time or distance (step 18). If set by time, then
It is determined whether or not the current traveling is during the rapid traveling period (step 19).

If it is during the rapid traveling period, it is judged whether or not AT ≧ 1/5 of the rapid traveling set time (step 19a), and NO.
If so, proceed to step 20, while if YES, RU
NTIM (elapsed time for sudden running) = 0 (Step 19
b), go to step 20. In step 20, RUN
It is determined whether or not the TIM is "0". If the TIM is "0", it means that the vehicle is running suddenly. Therefore, a buzzer sound "beep, beep" is emitted (step 21), and the process proceeds to step 22. "0"
If not, the process proceeds directly to step 22.

In step 22, RUNTIM (elapsed time of sudden running) is calculated. Then, it is determined whether or not the flag T = "0" (indicating that the mode button 11 is not pressed) (step 23), and if YES, the remaining rapid running time is displayed (step 24), and then , RUNTIM (elapsed running time) has reached a set time (step 25). On the other hand, if NO, the process proceeds directly to step 25.

If YES is determined in step 25 (RUNTIM has reached the set time), the process proceeds to step 57. On the other hand, if NO is determined, RUNTIM
Data is cleared with (elapsed running time) = 0 (step 26).

If it is determined in step 19 that the vehicle is not in the rapid traveling period (that is, during the slow traveling period), it is determined whether SLOWTIM (slow traveling elapsed time) is "0" (step 27). ), If it is "0", the slow running is started, and the buzzer sounding "pee" is emitted (step 28), and the process proceeds to step 29. If it is not "0", the process directly proceeds to step 29.

In step 29, SLOWTIM (slow running elapsed time) is calculated. Next, it is determined whether or not the flag T = "0" (indicating that the mode button 11 is not pressed) (step 30), and if YES, the remaining slow running time is displayed (step 31). To SLOWTIM
It is determined whether (slow running time) has reached the set time (step 32). On the other hand, if NO, the process proceeds directly to step 32.

If YES is determined in step 32 (SLOWTIM reaches the set time), step 57
Proceed to. On the other hand, if NO is determined, SLOWTI
Data is cleared by setting M (slow running time) = 0 (step 33). After that, the training set number (SET) is incremented (step 34), and SE
It is determined whether the value of T has reached the set value (step 3).
5). If YES in this determination, the process proceeds to step 57. On the other hand, if NO is determined, a buzzer sound "pee, pee, pee" indicating the end of the interval training is sounded (step 36), the interval training measurement is completed, and the number of times is cleared with SET = 0 (step). 37), and process AT = 0 (step 3
7a), and proceed to step 57.

Further, it is determined NO in step 18 (the training mode is set by distance).
If so, processing (steps 38 to 56a) in which the processing in steps 19 to 37 is replaced with the distance is performed. In order to replace the processing of steps 19a and 19b with the distance, A
TDST (distance that you would have run while stopped) = A
Calculation of T × AVS (step 38a), ATDST ≧ R
The determination process (step 38b) of ⅕ of UNDST (actual running distance) and the process of RUNST = 0 (step 38c) are performed.

In step 57, key input is received, and step 58, step 60, step 63, step 6
It is determined in step 4, step 66, and step 69 which key is pressed.

When the INTST / SP button 13 and the mode button 11 are pressed at the same time, the current training mode (time or distance) is displayed (step 5).
9) Go to step 6.

When the INTST / SP button 13 is pressed for a long time (step 60), it is judged whether or not the measurement is stopped (step 61), and if YES, processing such as training mode change processing (step 62). And go to step 6. On the other hand, if NO, the process proceeds directly to step 6.

When the reset button 21 is pressed (step 63), the process proceeds to step 1, and when the ST / SP button 12 is pressed (step 64), start / stop reversal is performed (step 65). . At this time, if the measurement operation is in progress, the measurement is stopped and “STOP” is displayed on the liquid crystal display unit. Conversely, if the measurement is stopped, the measurement is started and the “STOP” display is turned off at the same time. .

Next, it is determined whether or not the INTST / SP button 13 has been pressed (step 66). On the other hand, if it is determined that none of the buttons has been pressed after step 64, the process directly proceeds to step 66. If YES is determined in step 66, INTST = 1 is processed (step 66a), and interval training start / stop inversion is performed (step 67). At this time, if interval training is stopped, the abbreviation for training, “TR
"A" is displayed, and conversely, if the measurement is in progress, the measurement is stopped and the "TRA" display is turned off. If NO at step 66, step 68 is performed as it is.
Proceed to.

In steps 68 to 75, when it is judged that the mode button 11 has been pressed during the interval training, the running distance, the average speed, etc. are displayed only for 5 seconds after the button 11 is pressed, and after 5 seconds. This is the process of returning to the display dedicated to interval training.

In step 76, it is judged whether or not the mode button 11 is pressed, and if it is pressed, the display mode is set to maximum speed "MAX", traveling accumulated distance "ODO", traveling section distance "DST", average speed. "AVS", running time "TI
M ”and the time display are sequentially switched and displayed.

In the above-mentioned sequential display, when a predetermined key operation is performed while the "ODO" display is being made, the tire circumference display and its processing are carried out (steps 78-84). Further, when a predetermined key operation is performed while "DST" is displayed, processing such as display in the distance mode of interval training and change of setting contents are performed (steps 85 to 93). Also,
When a predetermined key operation is performed while "TIM" is displayed, processing such as display in the time mode of interval training and change of setting contents is performed (steps 94 to 102). Further, when a predetermined key operation is performed while “AVS” or “MXS” is displayed,
Data such as AVS and MXS is cleared (steps 103 to 108). If a predetermined key operation is performed while the time is being displayed, the time can be set (steps 109 to 113).

FIG. 15 is a flowchart showing a process for completely ending the interval training during the interval training, instead of temporarily stopping the interval training.

This flow is added after step 57. When step 57a is reached after step 57, it is determined whether or not the INTST / SP button 13 and the ST / SP button 12 have been pressed simultaneously. If not pressed simultaneously, the process proceeds to step 58. on the other hand,
If they are pressed simultaneously, the interval training measurement is stopped (step 57b) and "RUNTIM" is pressed.
"SLOWTIM", "RUNDST", "SLOWDS"
T "and the set count data are cleared (step 57).
c) Further, the process of INTST = 0 is executed (step 57d), and the process proceeds to step 6.

As described above, when the manual mode is selected as the interval training stop mode, when the user judges that the current traveling speed is lower than the speed set by the program, or when the pedal is actually used. In the case where the vehicle is running without inertia, it is possible to stop the progress of the training program by the interruption operation. Then, when the running speed that meets the conditions of the program can be maintained again or when the pedaling operation is restarted, the program can be advanced by the return operation, so the contents of the training program are not actually digested. However, it is possible to solve the problem that the program progresses over time.

When the auto 1 mode is selected as the interval training stop mode, when the pulse signal is not detected based on the traveling distance or elapsed time and the presence or absence of the pulse signal from the wheel rotation speed sensor 15, the training program is executed. Is stopped (that is, step 2 which is a time or distance counting process).
2, 29, 41, 48 does not pass), and the training program proceeds when a pulse signal is detected (passes steps 22, 29, 41, 48), so when the bicycle is stopped the program Progress will be automatically stopped, and it is possible to solve the problem that the program progresses due to the passage of time etc. even if the bicycle is stopped, and the user can stop the program manually one by one. There is no need to manipulate the restart.

When the auto 2 mode is selected as the interval training stop mode, the progress of the program is controlled based on the traveling distance or elapsed time and the presence / absence of a pulse signal from the wheel rotation speed sensor 15 as in the auto 1 mode. However, when the wheel stop time in the rapid running state becomes ⅕ or more of the rapid running time, the rapid running state is redone again (steps 19a, 19b, step 3).
8a to 38c), it is possible for the user to reliably carry out the set rapid travel.

Further, at the start of the progress of the training program, that is, the start of the sudden running state or the start of the slow running state, for example, a buzzer sound such as "beep, beep" is emitted (steps 40, 47, etc.). The user does not have to look at the speedometer frequently to check the progress of the program, which improves the concentration of training and improves the safety during training. It should be noted that the specific content of the progress status of the training program may be notified by voice, for example, "a sudden driving state has started."

(Embodiment 2) Another embodiment of the present invention will be described below.

In the first embodiment described above, the training program progresses based on only the distance traveled or the elapsed time (manual mode) or based on the distance traveled or the elapsed time and the pulse signal (auto 1, 2 modes). However, in this embodiment, when the traveling speed does not reach the set speed, the progress of the training program is stopped based on the traveling distance or the elapsed time and the traveling speed. When the speed reaches the set speed, the training program is advanced.

Specifically, instead of the pulse input determination process (step 16j, step 16k) in the automatic mode, a comparison process between the calculated traveling speed and the set speed is performed, and in each step, traveling speed ≧ setting When the speed result is obtained, the process proceeds to step 18, and when the traveling speed <the set speed is obtained, the process proceeds to step 57.

According to such a configuration, it is possible to solve the problem that the program progresses due to the passage of time, etc. even though the traveling speed has not actually reached the set speed, and the user manually operates one by one. Eliminates the need to operate program stop and restart.

[0066]

As described above, according to the present invention, although the bicycle is actually stopped, or the contents of the training program are actually undigested, the program can be operated over time or run. It is possible to prevent the vehicle from progressing depending on the distance, and improve the efficiency of training on a bicycle that actually runs on the road. Further, since the progress of the training program is notified by an audible sound or voice, the concentration of training can be improved and the safety during training can be achieved.
