Abstract

PURPOSE:To provide the data which clarifies relationship between the traveling condition and the force to be required for the traveling. CONSTITUTION:When the start key is operated (S3) after the weight of a bicycle and the weight of a rider are inputted (S1, S2), the traveling speed and the traveling distance are calculated (S4). These calculated traveling speed and the traveling distance are stored (S5), and then displayed (S6). Then, a judgement is made whether the flag F is reset or not (S7), and when the flag F is reset, the present speed V1 calculated in S4 is stored (S8). In addition, the process from S4 is executed again until the specified period of time is elapsed after the flag F is set (S9). Because the flag F has been already in the set condition, the loop of S4-S7 S10 is repeated. When the specified period of time is elapsed, the power is calculated (S12) after the speed V2 calculated in S4 in running the loop is stored (S11).

FIG. 3 is a circuit diagram of the transmitter 6. The reed switch 13 is normally off, and is turned on when the magnet 4 passes inside the transmitter 6 as the front wheel 2 rotates, and outputs the reed switch signal a to the detection circuit 14. The detection circuit 14 includes an oscillation circuit 15 therein, and when receiving the reed switch signal a from the reed switch 13, converts the reed switch signal a into a continuous clock signal b and sends the clock signal b to a base terminal of an NPN transistor 19 via a resistor 18. To do. A capacitor 20 is connected between the collector terminal and the emitter terminal of the transistor 19, the collector terminal is connected to one end of the electromagnetic induction coil 21, and the emitter terminal is connected to the detection circuit 14. A resistor 23 is provided on the other end of the electromagnetic induction coil 21 and one end of the capacitor 22.
The voltage Vcc is applied to the capacitor 22, and the other end of the capacitor 22 is connected to the emitter terminal of the transistor 19. Therefore, an electromagnetic induction signal is output from the electromagnetic induction coil 21 to which the clock signal b is given to the transistor 19.

FIG. 4 is a block circuit diagram showing the configuration of the receiver 7. In the figure, an electromagnetic induction signal from the electromagnetic induction coil 21 of the transmitter 6 is received by a reception unit 24 having an electromagnetic induction coil (not shown), and the CPU 25
Sent to. The CPU 25 is a program RO (not shown).
M, which operates according to the program stored in the program ROM and the data stored in the RAM 26 to control the entire receiver 7 and the display unit 8 via the display drive circuit 27. . CPU25
Includes a key input unit 2 including the plurality of keys 9 to 12.
9. Output signals are input from the clock circuit 28 that outputs the current date and current time.

The RAM 26 is provided with the registers 26a to 26j shown in FIG. The register 26a is a flag register that stores the set and reset states of the flag F. The register 26b is a timer register that measures a fixed time and is reset to 0 every time the fixed time elapses. The register 26c is a clock register, which stores the current date and current time input from the clock circuit 28, and the register 26d.
Front wheel 2 input by operating the other keys 11
The tire circumference data is stored. Also, register 2
6e stores the mass of the bicycle 1 input by operating the data input key 9, and register 26f stores the mass of the driver input by operating the data input key 9. The register 26g stores the traveling distance of the bicycle 1 within the fixed time, the register 26h stores the traveling speed V ₁ of the bicycle at the time when the previous fixed time has elapsed, and the register 26i stores the current fixed time. The traveling speed V ₂ of the bicycle at the time when has passed is stored. Further, the power rate calculated as described later is stored in the register 26j.

Next, the operation of this embodiment having the above configuration will be described with reference to the flow chart shown in FIG. That is, at the start of running, the driver performs an operation corresponding to the weight of the bicycle 1 and the numerical value of his / her weight on the data input key 9
Then, the vehicle weight of the bicycle 1 and the weight of the driver are input (S1, S2) and stored in the registers 26e, 26f. Next, wait until the start key 10 is operated (S3), and if the start key 10 is operated,
The traveling speed and the traveling distance are calculated (S4). That is,
When the front wheel 2 rotates and the magnet 4 passes inside the transmitter 6, the reed switch 13 provided in the transmitter 6 is turned on, and the reed switch signal a is generated as shown in FIG. . Then, the detection circuit 14 outputs the clock signal b of a predetermined cycle, and the transistor 19 repeats on / off for a minute time. Thereby, the electromagnetic induction coil 21 of the transmitter 6 outputs a resonance pulse (electromagnetic induction signal) with a short time immediately after the magnet 4 passes.

The electromagnetic induction coil 21 on the transmitter 6 side
When a resonance pulse is output from, the electromagnetic induction coil provided in the reception unit 24 generates a reception signal by the electromagnetic induction action. Therefore, this reception signal is input to the CPU 25 at the timing when the front wheel 2 makes one rotation and the magnet 4 passes inside the transmitter 6, that is, every time the front wheel 2 makes one rotation. Then, the CPU 25 counts this received signal,
The current traveling speed (hour speed) is calculated by "(3600 / count cycle) x circumference", and the traveling distance is calculated by "accumulated count number x circumference". Next, after the calculated traveling speed and traveling distance are stored (S5), they are displayed on 8b of the display unit 8 (S6).

Next, it is determined whether or not the flag F is reset (S7). If the flag F is reset, the current speed calculated in S4 is stored in the register 26h as the speed V _1. (S8). Furthermore, after setting the flag F (S9), it is determined whether or not a fixed time has passed (S10). If the fixed time has not passed,
The processing from S4 is executed again to calculate the traveling speed and the distance. At this time, since the flag F is already in the set state, the loop of S4 to S7 → S10 is repeated until the fixed time has elapsed. Then, after a lapse of a certain time, the traveling speed calculated in S4 during execution of the loop is set as the speed V ₂ and stored in the register 26i (S11), and then the power is calculated (S12).

That is, when the sum of the weight of the bicycle 1 and the weight of the driver is m, the acceleration is a, the distance traveled within a fixed time is L, and the time taken is t, the work rate P is P = (M
× a × L) ÷ t. Here, m is the register 26
e, 26f, acceleration a is a = (V ₁ −V ₂ ).
It can be obtained by / t. Further, L is calculated in S4 during execution of the loop and stored in S5, and t
Is a fixed time of S10 and is known. Therefore,
After calculating the acceleration a by a = (V ₁ −V ₂ ) / t, P
The work rate P can be calculated by = (m × a × L) ÷ t.

Then, the power P calculated in this way
Is stored in the register 26i (S13), and then displayed on 8a of the display unit 8 (S14). Then, after resetting the flag F (S16), it is determined whether or not the END key 11 is operated (S17), and the loop of S4 to S17 is repeated until the END key 11 is operated. Therefore,
By repeating this loop, the work rate is displayed on the display unit 8a at regular intervals while the bicycle 1 is running.

In this embodiment, the power is displayed on the display 8a of the display unit 8. However, the power calculated at every fixed time is stored and the printer is set to the receiver 7 after the traveling is completed. You may make it print out by connecting to. Further, it is also possible to adopt a configuration in which the gear of the bicycle 1 is automatically changed according to the calculated work rate.
