Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a stopwatch capable of setting a plurality of target split times.

[Prior art and its problems]

Conventionally, there has been known a stopwatch which can set a plurality of target split times and displays a time difference between an actually measured split time and the target split time.

For example, swimming, bicycle, like triathlon
In a series of multiple events such as marathons, the target split time for each event is set in advance so that the actual time spent in each event is delayed or faster than the target time. Can be easily known.

However, for example, when the time when a certain game is completed is significantly different from the target split time, it is necessary to set a new target split time based on the time when the game is next used.

In such a case, in the conventional stopwatch, the user has to reset all the target split times of the subsequent competition, and the correction operation is troublesome.

[Purpose of the invention]

An object of the present invention is to make it possible to easily correct a target split time.

[Points of the invention]

In the present invention, when a plurality of target split times are set and any target split time is corrected,
The point is that the subsequent target time is corrected by the correction time.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a circuit configuration diagram of an electronic wristwatch with a stopwatch function according to an embodiment of the present invention.

In FIG. 1, an oscillator 1 generates a clock signal having a constant cycle and outputs the clock signal to a frequency dividing / timing circuit 2. The frequency divider / timing circuit 2 divides the clock signal by 1/100
A time signal, such as a second signal or a one-second signal, which serves as a reference for time measurement is created, and a timing signal for controlling each block in time series is output.

The key input unit 3 is composed S ₁ to S ₆ key to be described later, and outputs an operation signal of those keys.

The ROM 4 is a fixed memory that stores a micro program for controlling the entire system. The ROM address control unit 5 is a block that controls a read address of the ROM 4 according to an instruction from the control unit 6. The control unit 6 includes a CPU and the like, and executes a time counting process, a stopwatch measurement process, a target split time correction process, and the like, which will be described later, according to a microprogram read from the ROM 4. Further, the control unit 6 writes and reads data to and from a register or the like of the RAM 7 composed of a random access memory when executing these processes.

FIG. 2 is a diagram showing the register configuration of the RAM 7. The time register T is a register for storing the current time data to be measured, and the register S is a register for storing the measured time of the stopwatch.

The register M is a mode register that stores a numerical value corresponding to the operation mode.
When = 0 is in the stopwatch display mode, M = 1 is stored.

The flag F is a flag that is set when the target time is set, and the flag E is a flag that is set during stopwatch time measurement.

the n stopwatch memory D ₀ to D _n is composed of a register D _X for storing a target split times, respectively, and register D _Y for storing the measured split time, a register D ₂ for storing their time difference ing. Further, the pointer P is one of the stopwatch memory D ₀ to D _n
Is a pointer to two addresses.

Returning to FIG. 1, the display control unit 8 is a circuit for controlling the display of the display unit 9 composed of a liquid crystal display device or the like, and outputs the current time data, the target split time data, and the measuring time output from the control unit 6. Display time data and the like.

Further, the buzzer drive circuit 10 and the buzzer 11 are circuits for setting an alarm time and the like, and notifying when the time to be measured reaches the set time or when the measured time of the stopwatch coincides with the target split time. .

Next, the operation of the embodiment having the above configuration will be described with reference to the flowcharts of FIGS.

FIG. 3 is a flowchart for explaining the overall processing operation. In step ST1 of the figure, first, it is determined whether or not the flag E is set, and it is determined whether or not stopwatch measurement is being performed.

If the flag E is set, the process proceeds to step ST2.
The register S is incremented by "1" based on the 1/100 second measurement side timing signal to update the measurement time.

Next, in step ST3, it is determined whether or not the timing is the timing of every second. If it is timed timing, the time data is updated in the next step ST4, and the updated time data is stored in the time register T.

Next, in step ST5, a key operation signal from the key input unit 3 is detected to determine whether any key operation has been performed. When a key operation has been performed, the process proceeds to step ST6 to execute a key process. Then, step ST7
To display the current time or measured time according to the operation mode.

Next, the contents of the key processing ST6 will be described with reference to the flowchart of FIG. 4 and the display state conversion diagram of FIG.

When any key operation is performed, step S1 in FIG.
In firstly operated key to determine whether S ₄ key. S ₄ when was key to determine whether the value of the mode register M in the next step S2 is "1", if M = 1, if more or flag F is in the next step S3 "0" Determine.

When M = 1 and F = 0, the stopwatch display mode shown in FIG.
At 0), and when the S ₄ key is operated, stopwatch memory D ₀ to D _n in the pointer P advances to step S4
Set the address to specify a memory D ₀ at the beginning of the,
Further, the flag F is set to "1" to switch to the target time setting state.

On the other hand, when was M = 1 and F = 1 is when the fifth in the target time setting state shown in Figure (2), S ₄ key target time setting etc. is completed is operated, step S5 To set the flag F to "0" and switch to the clear state.

When M ≠ 1 in the determination in step S2,
In the time display mode (M = 0) is when the S ₄ key is operated, to perform other S ₄ key processing proceeds to step S6.

If not S ₄ key that is operated is judged at the step S1, then the process proceeds to step S7, it is determined whether the operation or not of the S ₂ key. If S ₂ key that engineered, in step S8 mode register M is "1" and the flag F is "1"
Is determined.

M = 1 and F = 1 case, the target time setting state of the stopwatch display mode shown in FIG. 5 (2), S ₂
This is when the key is operated, and the flow advances to step S9 to move the pointer P to the next position. That is, in the target time set state, it is possible to sequentially specify the n stopwatch memory D ₀ to D _n by manipulating the S ₂ key.

Further, in the determination in step S8, M {1 or F}
When one is in a state other than the target time setting state of the time display mode or stopwatch display mode is when the S ₂ key is operated, to perform other S ₂ key processing proceeds to step S10. The other S ₂ key processing, for example M
= 1 and F = 0, for example, as shown in FIG.
By operating the S ₂ key in the clear state, the flag E = 1
And becomes time measurement becomes time measurement state is started, also is operated again S ₂ key while the E = 1 flag E = 0
As a result, the measurement is stopped and the measurement is stopped.
In other words, the start of the S ₂ key is time measurement, to function as a stop key.

In FIG. 4, what was operated in the determination of step S7 is
When not S ₂ key, to determine whether S ₅ key operation proceeds to step S11.

When the engineered were S ₅ key, at the next step S12, it is determined whether M = 1 and F = 1.

M = 1 and when F = 1, i.e. in the target time setting state of the stopwatch display mode, when the S ₅ key is operated, when order to set the target time,
It is time to select each digit of minute and second.
Each time the ₅ key is operated, the next digit is selected.

Further, if M ≠ 1 or a F ≠ 1 in the determination of the time step S12, in a state other than the target time setting state of the time display mode or stopwatch display mode, S ₅
It is when a key is operated, to perform other S ₅ key processing proceeds to step S14.

For example, if S ₅ key is operated in the state of stopping to measure the M = 1, F = 1, E = 0 shown in FIG. 5 (3), first the first measurement split among the stopwatch memory D ₀ to D _n time is displayed, S ₅ key each time it is operated in the next memory area measured split time is displayed below.

Returning to FIG. 4, the engineered in the determination of step S11 is not the S ₅ key, to determine whether S of ₆ key operation proceeds to step S15.

If S ₆ key of engineered, whether on whether proceeds M = 1 and F = 1 step S16, i.e., the operation of S ₆ key determines whether performed in target time setting state of the stopwatch display mode .

When M = 1 and F = 1 in step S17, first, the pointer P is determined whether or not the instruction address D ₀ of the first memory D ₀ stopwatch memory. When the pointer P is indicated memory D ₀ of the top, at the next step S18, the selected digits and the memory D ₀ following values of the same selection order of magnitude as the memory D ₀ of the memory in the memory D ₀ is incremented by "1" I do.

If this time is P ≠ D _0, the pointer P advances to step S19, it is determined whether or not shows second memory D _1. When instructs the second memory D _1, at the next step S20, the selected digits and the memory D ₁ the following values of selected digits of each memory of the memory D ₁ is incremented by "1".

If P ≠ D ₁ is determined at the step S19, the process proceeds to step S21, it is determined whether the pointer P is pointing to a third memory D _2. If P = D _2, is incremented by "1" the value of the selected digit following memory including memory D ₂ at the next step S22.

If this time is P ≠ D _2, following the procedure proceeds to step S23,
The same determination is sequentially performed for the memories D ₃ , D _4, ..., And the value of the selected digit of the memory indicated by the pointer P and the subsequent memory is incremented.

Thus, for example, when the target split time is set in each of the stopwatch memories D _{0 to} D _n and the target split time in any one of the memories is corrected, the subsequent memories are corrected by the correction time at that time. The target split time is modified at the same time. Therefore, even during a game or the like, when the difference between the actually measured time and the target split time is large, the subsequent target time can be easily corrected.

On the other hand, when M ≠ 1 or F ≠ 1 in the determination of the step S16, since when the S ₆ key is operated at a time other than the time display mode or target time setting state, step S2
Proceed to the 4 to run the other S ₆ key processing.

In the other S ₆ key processing, for example, FIG. 5 (4) M = 1 shown in, F = 1, operating the S ₆ keys in the measurement state of E = 1, pointer measurement time at that time as a split time While being stored in the stopwatch memory addressed by P, the time difference between the measured split time and the target time is displayed on the display unit 9. Moreover, by operating the S ₆ key when the time difference between the target time is displayed,
The pointer P is updated so that the next stopwatch memory is addressed, and the time being measured is displayed again.

If it is not the operation of S ₆ keys in the step S15 is determined, the process proceeds to step S25, other keys, namely S ₁
Key, key processing of S ₃ key is made.

Although not described in detail the processing of S ₁ key, the S ₁ key is a key for switching the operation mode, the fifth, as shown in FIG time display mode by operating the S ₁ key (M
= 0) and the stopwatch display mode (M = 1) can be alternately switched.

The set, S ₃ key stopwatch stop state, i.e., when M = 1, F = 1, E = 1, the flag F to 0 to clear the measurement data are displayed as shown in FIG. 5 5 (1). At this time, the stopwatch memory D ₀ to D _n of the measurement time register D _y, the value of the time difference register D _z is adapted to be cleared.

It will now be described with reference to FIG. 6 for the data to be stored in the stopwatch memory D ₀ to D _n When the above processing has been executed.

Figure 6 (a) shows the contents of the register when the finished configuring the target split time, the target time register D _X of each memory D ₀ to D _2, from the start of measurement that are set respectively Target split time "10'00" 00 ",
"25'00" 00 ","45'00"00" and the like are stored.
Further, the pointer P is in the initial state are indicated the head memory D _0.

When S ₆ key is operated after the time measurement is started in this state, as the time of measurement stored in the register S as shown in FIG. (B) "15'00" 01 "is measured split time, It is stored in the first memory D ₀ of the measurement time register D _Y. Further, "time difference" 00 "5'10 target split time 10'00""In this case the measurement split time 01" is stored in the time difference register D _z.

FIG. 6 (c) shows the contents of the register when the third split time measurement is completed. The measurement time register D _y of each memory, first time, second time, the third split time, are respectively stored in the time difference register D _z, measured time difference between the split time and the respective target time Is stored.

By this way, the stored data S ₅ key 5
It can be known from the result display shown in FIG. However,
From these result displays, it can be seen that there is a difference between the measurement result and the initial target time only for 5 minutes or more. Therefore, S ₃ by operating the key measurement time register D _y, correct target time of the memory D ₀ in the target time setting mode of FIG. 5 (2) by operating the S ₄ key after clearing the time difference register D _z I do.

Figure 6 (d) are out of target split times shown in FIG. 6 (a), shows the contents of the memory when the corrected target split time of the first memory D _0. For example, 1
Change the target split time from "10'00" 00 "to" 15 '
When corrected to 00 "00", the corrected time is added to the subsequent target time of the memory, in this case "5'00" 00 ", and corrected to"30'00"00" and "50'00" 00 ", respectively. You.

Thus when modifying the arbitrary target time in the stopwatch memory D ₀ to D _n, because at the same time the target time subsequent memory area is modified by modifying time period, when the next performing the same measurement The operation of correcting the target time is simplified, and the target time can be easily corrected according to the actual measurement time.

The present invention is not limited to the electronic wristwatch described in the embodiment,
The device may be a device dedicated to the stopout, or may be incorporated in another electronic device.

[Effect of the invention]

According to the present invention, when an arbitrary target time out of a plurality of set target times is corrected, the subsequent target times are simultaneously corrected. become.
