The RAM 3 consists of an upper-stage display register X, a lower- stage display register Y, a stopwatch register SR, plural lap storage registers LR, a lap frequency storage register KR, a distance storage register DR, a contents display changeover register M, a distance setting mode flag S, etc. When a key is pressed in each display mode, its key processing is performed and the mode is switched to a distance setting mode. In this mode, distance data required to display respective tachymeter data in split tachymeter mode and lap tachymeter mode. Then, a tachymeter display is made on the basis of the new distance data.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stopwatch device having a tachymeter function.

[Conventional technology and its problems]

Conventional stopwatch devices not only display time data from start to stop, but also use a so-called tachymeter, which sets distance data in advance and calculates and displays the speed based on the time and distance when the device stops. There are things that have functions.

However, in the conventional device, once the distance data is changed, the previous time data is cleared. Therefore, there is a drawback that the tachymeter cannot be updated by changing the distance data, that is, the distance data must be set before measuring the time data in order to display the tachymeter.

[Purpose of the invention]

In view of the above-mentioned problems, the present invention aims to provide a stopwatch device with very high operability, which allows the distance meter to be updated even if the distance data is changed.

[Key points of the invention]

In order to achieve the above-mentioned agreement, the present invention is designed to display the distance glt meter again based on the new distance data when the distance glt data is changed.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a circuit diagram according to an embodiment of the present invention. In the figure, ROMI is a fixed memory that contains programs and data that control the entire system. The ROM address control section (ROMA) 2 is an address section of ROMI' that defines the program flow, and is

The output from 0 is input. RAM3 is ROMI
71・Res data output S1. L1SL and Nine FL
This is a memory that outputs data at addresses determined by the ALU 5, and inputs and stores the results of each data being processed and processed by the ALU 5. Instruction decoder (IN
sTDEc) 4 is a block that decodes the output Ins of ROMI and sends a control signal to each block. ALU5 performs arithmetic and logical operations using S and F as inputs, and writes the output to the address of R/\M3 designated by the outputs Fμ and FL of ROMI. Lunch (1=A
TCI() 6 temporarily stores the contents of the address of RAM3 specified by the output 5IAXSL of ROMI,
It is synchronized with the input F of the eight LU5 and sent to the input S of the ALU5.

The oscillator (O3C) 7 outputs a clock signal with a constant period, and the timing generator (TTM ING) 8
divides the frequency of the above-mentioned 1 cock signal to a predetermined frequency and outputs a timing signal for controlling each block in time series. The key human power unit (KEY) 9 is a block that sends signals for instructing the system to perform various processing operations. The frequency divider circuit (DIV) 10 is a counter that divides the output from the SC7, and sends a clock signal with a constant (1/100 second) period to the RAM 3 or the like to perform a clock process.

The display circuit (DISP) 11 is a circuit block that displays processed data, and the buzzer circuit (BUZZ) 1
2 is a circuit block that generates a buzzer signal based on data from the pass line.

Bus control gates AlA2, Bl, B2, C1~
C4, Dl, and D2 are gates that control each pass line based on the output of the IN5TDEC4.

Next, FIG. 2 shows a specific internal configuration of the RAM 3 mentioned above.

As shown in the figure, the RAM 3 includes an upper display register
1 display mode flag, ramp difference mode flag N, average lap mode flag 0, lap cut mode flag P, split cut mode flag Q, distance setting mode flag S
It is composed of etc.

The upper display register X and the lower display register Y are registers for storing the contents displayed in the upper and lower stages of the display, respectively, as shown in FIG.

The stop and start register SR is a register that stores the elapsed time after the start of the needle side. Lamp memory register LR
is composed of multiple registers, and the wrap time is sequentially written into each register. Note that the lamp time referred to here is the time that has elapsed since the previous operation of the lap switch SL when the lamp switch SL, which will be described later, was operated during stop/watch measurement. Therefore, the ramp number storage register KR is a register that stores the number of laps taken, that is, the number of ramps,
The distance storage register DR is a register that stores distance data necessary for displaying a distance meter.

Further, when the display mode flag L is set to "1", the display mode shown in FIG. 5 is the lap difference mode M1.
, average lap mode M2, lap mode M4, or split mode M3, and when "0" is set, other normal total mode M6, lap and sprint mode M8, etc. Note that the term "split" here refers to the time from the start of measurement. Therefore, when the ramp difference mode flag N1 average lap mode flag 0, the lap mode flag P, the split speed mode flag Q1, and the distance setting mode flag S are set to "1", the display mode is the ramp difference mode. M + , average lap mode M2, lap cut mode M4, split cut mode M3, and distance setting mode M+a are flags. The content display switching register M is a counter that counts sequentially at predetermined time intervals as described later, and according to this count value, the above four display modes (lap difference mode M + , average ramp mode M2, split cut mode M3, Each content display in the lap wood meter mode M a ) is switched.

The contents of each of the above registers It is updated sequentially based on each data output from KEY9 and AL:U
5 and DISPll sequentially.

Next, the main processing operations of this embodiment having the circuit configuration as described above will be explained.

In Fig. 3, first check whether there is a clock clock every 1/100 seconds (aI), and if there is a clock clock, set 1 (= 1/1) to the strike watch register SR.
00 seconds) is added (a5), and if not, it is determined whether any key has been pressed (a2). In this example,
A key 81 for starting and stopping measurement, a key 32 for switching the display mode, a key 83 for switching the display mode whose switching order is reversed from that of the key 82, and a key 83 for switching the display mode, and a key 83 for switching the display mode. It is provided with a key 84 for distance setting, and a key SL for displaying lap display, split display 1, and FW removal.

Therefore, in the above step a2, if none of the above keys is pressed, the process returns to step a1, and if any key is pressed, the process moves to the next key process (a3), and the key chuck process (a4) is finished. Then return to step a1.

Here, the above key processing (a3) will be specifically explained based on FIG. 4.

First, check 111 whether the pressed key is key 82 or not.
definitely b+), if key S2, display mode flag L
is 1, that is, whether the display mode is one of lap difference mode M + , average lap mode M2, lap running mode M4, and sprint running mode M3 shown in FIG. 5 (b2). If L = 1, set the content display switching register M to O, set the display mode flag L to 1, set the lap difference mode flag N to 1, and perform the calculation to obtain the ramp difference. (b3). This calculation is performed by determining the difference between two ramp times stored in the lap storage register LR.

On the other hand, if L=1 in step b2 above, it is determined whether the lamp difference mode flag N is 1 or not (b4), N
If =1, N is set to 0, average lamp mode flag 0 is set to 1, and calculation is performed to obtain the average lamp (b5).

This calculation is performed by calculating the average of the lamp times stored in the lap storage register LR up to the desired number of laps.

If N≠1 in step b4 above, determine whether the average lap mode flag 0 is 1 (bδ),
If O=1, set O to O, set the sprint mode flag Q to 1, and perform calculations to obtain split display (b7). This calculation is performed by dividing the distance preset in the distance storage register DR by the split time measured in the distance register SR.

If 0≠1 in step b6 above, it is necessary to judge whether the split mode flag Q is 1 (be), Q-
In the case of 1, Q is set to O, the lamp kuki mode flag P is set to 1, and the calculation for obtaining the lap kuki is performed (be). This calculation is performed by dividing the distance preset in the distance storage register DR by the desired ramp time stored in the lap storage register LR.

In step b8, if Q≠1, that is, if the lamp mode flag P is 1, P is set to O and L is also set to 0 (boo). That is, the display mode is switched to normal measurement mode or lap and split mode.

Also, if the key is not S2 in step b+ above,
Determine whether the key is S (b++), and if so, determine whether the key is L-1 (b
+2). If L≠1, 0 is set in the content display switching register M.
is set, L is set to 1, the ramp mode flag P is set to 1, and the lap difference calculation as described above is performed (b+3).

If L=1 in step t)+2 above, P is 1
If P = 1, set P to O and set the sprint mode flag Q to 1, and perform the sprint calculation described above (baa).
. Moreover, in the case of P≠1 in the above step baa,
It is necessary to judge whether Q = 1 or not (b
l 7) - In step b+s above, if Q≠1, determine whether 0=1 b + s), and if O=1, set O to O.
At the same time, the lamp display mode flag N is set to 1, and the above-mentioned lap difference calculation is performed (b+9). On the other hand, if O≠1 in step b1B, that is, if the ramp difference mode flag N is 1, N is set to O and L is also set to 0 (b2a). That is, the display mode is switched to normal measurement mode or lap and split mode.

In this way, the order in which the display modes are switched is simply reversed between when the key 82 is pressed and when the key S3 is pressed. That is, when key S2 is pressed, each flag is switched in the order of N, O, Q, P and set to 1, whereas when key 83 is pressed, P, Q, 0, N are switched. They are set to 1 by switching in order. This switching of display modes will be described later based on FIG. 5.

Next, if the key is not the key S3 in step b++, it is determined whether the key is the key S4 (b21), and if so, it is determined whether L=0, that is, the four display modes M
+, M 2 , M 3 , and M 4 (bz2).

If L=O, it is determined whether the distance setting mode flag S is 1, that is, the display mode is the distance setting mode Mh.

(b23), and if S=1, set S to 0
b2t), if S≠1, set S to 1.
25).

When L≠0 (hitting L=1) in step b22 above, check whether S is 1 in the same way as step b23 above (b26), and if S=1, set S to O b27
), when S≠1, set S to 1 (b2a). S=
When it is 1, it is further determined whether the lamp kuki mode flag P is 1 and whether the hitting display mode is the lap kuki mode M4 (b29). If P=1, the above-mentioned wrap difference calculation is performed (b30). On the other hand, when P≠1, it is necessary to judge whether the split kuki mode flag Q is 1 and whether the hitting display mode is split kuki mode M3 b3+
), when Q=1, perform the sprite sotokuki operation (b32
).

That is, by operating the key 84, the normal measurement mode, lap and split mode, and distance setting mode M can be selected.
Mutual switching with HO or 4 display modes M
Mutual switching between I, M2, M3, M4 and distance setting mode M+o is performed. In particular, split kuki mode M
3 or distance selection mode M from lap kuki mode M4
After the mode is switched to HO and new distance data is set here, when the mode is switched to mode M3 or 7 or M4 described in "Baidu", the time data is not cleared and step b32 or above is executed. Each calculation of b3o will be performed based on the new distance data.

Note that if the key is not the key 84 in step b21, processing is performed on another key 81 or SL, etc. (b33
).

Next, we will return to FIG. 3 to continue the explanation.

If there is a 1/100 second timing clock in step al, a timing process of adding 1 to the stopwatch register SR is performed (a5), and then it is checked whether the display mode flag L is 1 or not, that is, the display mode is Lap difference mode M1 (N=1) and average lap mode M2 shown in FIG.
(0=1), split punch mode M3 (Q=1), or wrap punch mode Ma (P=1) (a6). If L≠1, other mode displays, ie, measurement display, U, B, sub-resolution 1- display, etc. are performed (a7), and then the process returns to step a1.

On the other hand, if L=1, determine whether 2 seconds have been counted (ao); if not yet, return to step a1; if 2 seconds have been counted, add 1 to the content display switching register M ( a9). Next, determine whether the content of M is an even number (a + O), and if it is an even number, determine which mode the display mode is, i.e. 1 among each flag N, 0, Q, P. is set (a+1).

In the case of N=1, that is, in the case of lap difference mode M1,
As shown in display mode M++ in FIG.
"P dlF" is displayed (a12), and the lap difference time is displayed at the bottom (aI3).

In the case of 0=1, that is, in the case of average lap mode M2, "A" is displayed in the upper row as shown in display mode M21 in FIG.
Displays the content “V-LAP” (a + 4),
The average lap time is displayed at the bottom (al 5).

When Q or P=1, that is, in the split mode or lap mode, "TA" is displayed in the upper row as shown in display mode M31 or M41 in FIG.
CT(Y") is displayed (aI6). Then, it is determined whether P=1, that is, whether the wrap mode is M4 or not. If P=1, as shown in display mode Ma+, The lap cutting mode is displayed in the lower row (a 1θ). On the other hand, if P≠1, that is, Q=1, the lower row displays the splint cutting mode as shown in display mode M31.
Display the Kuki data (a19).

Further, if the content of M is an odd number in step a+Q, it is determined which display mode is in the same way as in step al+ (a 2 a).

Here, if N=1, that is, in the case of lap difference mode M1, as shown in display mode M12 in FIG.
-xxx” is displayed (a2+), and the lap difference time is displayed at the bottom (a+3).

If O or Q=1 in step a20, that is, average lamp mode M2 or split lamp mode M
In the case of 3, as shown in display mode M22 or M32 in FIG.
XXX” is displayed (a22).Then,
Determine whether O = 1, that is, whether it is average lap mode a2: +), if so, display the average lap time in the lower row aI5), if ○≠1, that is, Q
If = 1, display Suburi Sotokuki data in the lower row (
aI9).

When P=1 in step a2Q, that is, when the lap writing mode M4 is selected, "LAP XX" is displayed in the upper row to indicate the number of laps, as shown in the display mode M112.
The content is displayed as "X" (a24), and the lap cookie mode is displayed in the lower row (a+θ).

As is clear from step ae%a9, the content of the content display switching register M switches between even and odd numbers every 2 seconds, so the content display in the upper row also changes from step ago to step a12, a14, and ale. a21
It will switch between %a22 and a2a every 2 seconds.

Next, each of the above-mentioned keys SL, S2, S3, S4, S L
Both cases and switching of the display mode when they are operated will be explained based on FIG. 5.

First, in reset mode M5, zero is displayed in the upper and lower rows. In this state, each register X, Y, SR, LR, KR, M and each flag L, N,
0 is set in O1P, Q, and S.

If the key 81 is pressed in the reset mode M5, the mode switches to the measurement mode M5, the stopwatch register SR starts measuring, and the elapsed time after the start of the measurement is displayed in the upper and lower rows. The number "1" at the left end of the upper row indicates the number of lamps. This number of laps is stored in ramp number record 1, q register KR. In this state, S1 again
If is pressed, the mode switches to measurement stop mode M7, measurement stops, and the display 'EJJ' on the upper and lower rows also stops. If the key S1 is further pressed here, the mode is switched to the measurement mode M5 and the measurement is restarted. Further, if the key SL is pressed in the state of mode M7, the mode is switched to reset mode 15M5.

When key SL is pressed in measurement mode M6, the mode switches to lap and split mode M[+, where the lap time is displayed on the upper row and the split time is displayed on the lower row. If the key S1 is pressed in this state, the mode switches to the lap and sprint stop mode M9, and the measurement is stopped while the 19 display state remains unchanged.

If the key S1 is pressed again, the mode is switched to the lamp and streak mode M8, and measurement is resumed.On the other hand, when the key SL is pressed, the lamp and split display are canceled and the mode is switched to the measurement stop mode M7.

When the key 82 is pressed in each of the above modes M5 to M9, the display mode flag L and the lap difference mode flag N are set to 1, and the content display switching register M is set to 0 (steps in FIG. 4). b3), the display mode is switched to one display mode M++ of the lap difference modes M1, and a lap difference display is performed (step a in Fig. 3).
12, a13). Two seconds later, M counts 1 (ae-, aq), so the display mode M++ is switched to the other display mode M+2 (a21, a13). In this way, in the lap difference mode M1, the display mode M+
+ and display mode M+2 switch every 2 seconds. Therefore, if you look at these two types of content display, in the example in Figure 5,
It can be easily seen that the difference in time between the second and third ramps is 3 seconds and 18 seconds.

If the key 82 is pressed in the lap difference mode M1, the average lap mode flag 0 is set to 1 (b5)
, the mode is switched to average lap mode M2, and average lap display is performed (a14, a15, a22). In this case as well, 2
Since the display mode M21 and the display mode M22 are switched every second, it can be easily seen that in the example of FIG. 5, the average lap time up to the third lamp count is 3 minutes 17 seconds 28.

If the key 82 is pressed in the ramp difference mode M2, the sprint stop mode flag Q is set to 1 (b7
), the mode is switched to sprint mode M3, and a split mode is displayed (ale, a19, a22). Similarly to the above, the two display modes M 31 and M 32 are switched every two seconds, and in FIG. 5 it can be immediately seen that the speed up to the third split is 182.51 km/hour.

When key 82 is pressed in sprint mode M3,
Since the wrap mode flag P is set to 1 (b9
), the mode changes to rough pukuki mode M4, and a lap difference display is performed (ale, ale, a24). In this case as well, 2
Since the two display modes M a l and M a 2 switch every 2 seconds, the speed at the same time for 3 lamps is 210.48.
You can know that it is km/hour.

If the key 82 is pressed in the rough pukuki mode M4, the display mode flag L is set to O (boo), so the mode is switched to one of the above-mentioned modes M5 to M9, and the display thereof is performed (a7).

On the other hand, if the key 83 is pressed, the key processing (b) shown in FIG.
++~b20'), the display mode is switched in the reverse order of the key S2. That is,
From each of the above modes M5 to Mg, there is a lap kuki mode M4, a suburi no tokuki mode M3, an average lap mode M2,
Switches to lap difference mode M1 and returns to modes M5 to M9
Return to In this case as well, the contents displayed in the upper row of each mode M + -M 4 are switched every 2 seconds.

Next, in each display mode MI-M9 described above, key 8
If you press 4, that key process is performed (b2+),
Switches to distance setting mode Mho.

In this mode, it is possible to set distance data necessary for displaying each piece of wood data in the above-mentioned Suburi Sotokuki mode M3 and Lap piece mode M6. After completing the settings, press key 84 again.
The display mode switches to the previous display mode M+ to M9. Therefore, when the kuki meter is displayed in the lap kuki mode M4 or the suburi no tokuki mode M3, the distance setting mode M! It is also possible to set new distance data by switching to ``o'', and thereafter, a makeover display is performed based on the new distance 311 data. That is, the setting of the distance Mli data can be performed sequentially when a close-up display is required.

In addition, in the above embodiment, the content display for explaining the various measurement information displayed in the lower row was performed using two types of data that alternately switch in the upper row, but it is possible to switch and use three or more types of data. This allows for more specific display. Furthermore, the upper and lower display devices fj may be interchanged.

〔Effect of the invention〕

As explained above, according to the present invention, when distance data is changed, it is possible to update the distance meter based on the data, and therefore, the timing of setting distance data is not limited to before the measurement of time data; Even during measurement or after measurement, the make-up display can be performed sequentially when necessary, so the operability is greatly improved.
