Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a time data storage device capable of storing and displaying a large number of time data such as timetables of trains, buses, airplanes, daily schedules, and the like.

[Prior art]

Conventionally, it has been considered that a large amount of time data such as a timetable is stored in a memory and arbitrarily read from the memory and displayed. For example, in Japanese Unexamined Patent Publication No. 56-119885 published on September 19, 1981, many time data of a timetable are stored in a memory, and the current time obtained by a clock circuit is stored in the memory. There is shown an electronic timepiece which generates an alarm sound when it approaches the time data being displayed so as not to miss a train or the like.

[Problems of conventional technology]

However, the time data stored in the timetable is extremely large, and it is troublesome to generate an alarm sound for the large number of time data. Further, if only the time data of the timetable of one station is stored, it can be recognized that the alarm sound is the time data of that station, but that is extremely inconvenient in daily life. For example, the time data of the timetables of a plurality of stations is required when going to and returning from a company, or when transferring to some stations. However, in the publication technology shown as the above-mentioned conventional example, these are required. However, if an alarm sound is generated, it is not clear which station the alarm sound corresponds to the time data of.

[Object of the Invention]

The present invention has been made in view of the above circumstances, and an object thereof is to notify an alarm when the boarding time approaches, and to display which boarding station name and boarding mark the alarm sound indicates. An object of the present invention is to provide a time data storage device that is extremely easy to use by making it obvious at a glance whether it is timetable data.

[Main points of the invention]

In order to achieve the above object, the present invention stores a station name data of each station and a time table data of each station in a storage unit, and a station name designated from among the stations. A station name storage unit and an identifier storage unit that stores an identifier indicating whether or not to display a boarding mark when approaching the time at which you want to board are provided, and the alarm data setting means is stored in this timetable data storage unit for each station. Select a predetermined station from the time data of the timetable of No. 1 and write it in the station name storage unit, and specify the time data you want to board from the time data of the timetable of the selected station Write an identifier indicating that the boarding mark is displayed. Then, when the alarm display means makes a predetermined relationship between the time data of the timetable designated by the alarm data setting means and the current time, while alarming that the time to get on is approaching, Since the station name read out from the station name storage unit and the boarding mark according to the contents of the identifier storage unit are displayed on the display means, which boarding station the alarm notification when the boarding time approaches corresponds to the timetable data of which boarding station It is intended to let you know.

FIG. 5 shows the relationship between the display mode that changes due to a switch operation and the like, and the value in the mode storage section M of the RAM 6 in FIG. That is, in the present time display mode, the present time and the station name of the station which is selectively designated by the station name selection storage unit N among the plurality of station names are displayed as will be described later. In this state, the value of M Is 0. However, when the switch S ₃ is operated, the timetable display mode is entered and M becomes 1 and the station name of the designated station and the timetable of the station are displayed and the designated station name is changed. You can also In this display mode, the switch
When S ₂ is operated, M = 3, and new setting of the timetable and correction or change of already set data are possible.
Also, when switch S ₄ is operated in timetable display mode, M
= 4, which is the mark set mode in which you can select and set the time data that will alarm you when you approach the time you want to ride, out of the time data in many timetables of the selected station. In the above-described current time display mode, when the time is 30 minutes before the time data of the timetable that has been set in the mark set mode, M = 5, an alarm is sounded, a timer is displayed, and the timetable is displayed. It will inform you of the number of minutes left until the set time data. Further, when the switch SA is operated in the current time display mode, M = 2, and the next time data, which is the closest to the current time, among the time data in the timetable of the specified station described above is displayed. ing. However, in FIG. 5, the relationship between the display mode and the value of M is shown by which of the station name, the current time, the timer time, the time data of the timetable, etc.
This is because it is performed on the basis of the value of, and the specific display contents and the change of the value of M will be described in more detail later.

Next, FIG. 6 is a general flow showing the flow of the overall processing of the circuit shown in FIG. In the figure, 24a
Indicates a standby (HALT) state. For example, if there is a signal every 1/16 seconds, step 24b for clock processing and step 24c for display processing are displayed.
The process proceeds, but proceeds to switch S ₁ to S _5, SA, when any one of the SB is operated step 24d in the standby state.

FIG. 7 shows a detailed flow of the timing processing and the display processing of steps 24b and 24c of FIG. However, the step 25a is the present time counting process, and the contents of the present time counting register 21 of the RAM 6 are incremented by 1 every time the 1/16 second signal is output.
If each time unit matches the carry condition numerical value, the upper unit is incremented by 1 to obtain the current time data, and the current time count register 21 is written and stored. The next step 25b is a step of judging whether or not the minute has been corrected in the above step 25a. That is,
The subsequent steps 25b to 25l have been described above. It is a process to make an alarm from 30 minutes before the time you want to ride in the timetable,
Since this processing is performed every minute, the presence or absence of minute carrier is determined in step 25b. However, if there is a minute carry, the process proceeds to step 25c.
Of the timetable data storage areas 22a to 22h of the RAM 6, in the storage area designated by the station name selection storage section N, it is determined whether or not any address is stored in the mark address storage section F ₀ . That is, it is determined whether or not the above-mentioned desired time data for the ride is selected and set. Then, if the setting is made, the process proceeds to step 25d, and it is judged whether or not the current time of the register 21 is 30 minutes before the time data addressed in the mark address storage section F ₀ , 30 minutes before. If it is determined that the time has passed, the process proceeds to step 25e, the timer memory P is preset with "30 minutes" data to start the subtraction operation, the mode memory M is set to "5", and the flag L is set. "1" is written in, and the alarm sound is generated in step 25f. If it is determined in step 25d that it is not more than 30 minutes ago, proceed to step 25g
It is judged whether it is minutes before or not, and if it is 20 minutes before, at step 25h, an alarm sound different from that at step 25f is generated.
Also, in steps 25i and 25h, a match was detected 10 minutes before, respectively.
10 minutes ago, the steps 25f and 25h described above in step 25j
An alarm sound different from that is generated, and if they match, M and L are set to "0" in step 251.

Steps 25m to 25s show the details of the display processing of FIG. First, in step 25m, it is determined whether or not the value of the mode storage section M of the RAM 6 is 0, and if M = 0, the station name is selected in step 25n (the storage area 22a selectively designated in the station name selection storage section N). 22h), the data stored in the station name storage section 23a) is displayed on the dot matrix display sections 2a to 2e of FIG. 2, and if the mark to ride is set (mark address storage section F of RAM6). _If the address is stored in ₀ ), display the mark display 2h in Fig. 2,
Furthermore, the day of the week, the date, and the time in the register 21 of the RAM 6 are displayed. This display is made by sending necessary data to the display register 20 of the RAM 6, respectively. FIG. 8A shows
The display state in the mode of M = 0, that is, the current time display mode is shown. It shows that the current time is Thursday, September 25, 11:25:00, and Tokyo station is selected as the timetable. . However, if the address of the time data of 11:25 is set in the mark address F ₀ of the memory area 22a of the RAM 6, for example, when the current time becomes 10:55, the step 25
30 minutes before is detected and M = 5 at step 25e. In step 25q, if M = 5 is determined, the process proceeds to step 25r, and the station name (TOKYO) day of the week (TH), the timer time (30 minutes) in the timer memory P and the current time (10:55) are shown in FIG. Display as B. In this case, the mark display body 2h is the flag L.
Since 1 is 1, the blinking display is performed. However, when the time advances and it is 20 minutes before 11:25, the display as shown in FIG. 8C is displayed and an alarm sound is generated. 10 minutes before, an alarm sound is generated again, and when the time reaches 11:25, M and L are set to 0 by step 25l, and the normal time display is returned as shown in FIG. 8D. At this time, an alarm sound may be further generated.

As described above, according to the above flow, the subtraction timer is operated and displayed from 30 minutes before only the desired time data of the desired station among the large number of time data of each of the plurality of stations, and the alarm is generated. Will be informed.

FIG. 9 is a detailed flowchart of the key processing in step 24d of FIG. That is, it is determined which switch has been operated in steps 26a to 26e, and each step 26f
The key processing for each switch is performed in the range from 26 to 26h. The switch SB is omitted. However, when the switch S ₁ is operated, the S ₁ processing of step 26f is
Details are shown in the figure.

In FIG. 10, when the switch S ₁ is operated, it is first determined in step 27a whether the value of M is 1 or not. That is, the fifth
It is determined whether or not the timetable display mode shown in the figure is present. When it is determined that the value of M is 1 in the above step 27a, the process proceeds to step 27b, the contents of the station name selection storage section N of the RAM 6 is incremented by 1 to specify a new station, and the timer C of the RAM 6 receives, for example, 2 seconds data. At the same time as the setting, the subtraction operation is started, and at step 27d, the number of remaining time data sets in the timetable of the newly designated station is calculated in the selection storage section N, and the remaining number register Q is preset. And among the time data of the timetable for the next step 27e in the selected station, the address of the four time data closest to the current time is stored in each address storage unit F ₁ to F _4. However, the result of each such step processing is displayed by the display processing of step 25s in FIG. 7, and the details of this step 25s are shown in FIG. In FIG. 11, in step 28a, it is judged whether or not M = 1, and M
If = 1, the process proceeds to step 28b. In this step 28b, it is judged whether or not the value of the timer C has reached 0. If it is not 0, the process proceeds to step 28c and the subtraction operation of the timer C is performed, and at the same time, the station name selected in the selection memory section N is selected in step 28d. , The remaining number in the remaining number register Q is displayed. FIG. 12 shows a change in the display state in the timetable display mode with M = 1. For example, as shown in FIG. 12A, TOKYO
When switch S ₁ is operated when is displayed, a new station (OSAKA) is selected and designated (N is updated), the station name and the remaining number of stations ( 57
Shows the state in which the value of timer C is displayed for 2 seconds when the value becomes 0. However, when the value of timer C becomes 0 after 2 seconds, the process proceeds from step 28b in FIG. 11 to step 28e, and as shown in FIG. 12C, the time data closest to the current time of the station (OSAKA) is displayed. It is what is done. Thus, when the switch S ₁ is operated when M = 1 (timetable display mode) in the S ₁ process of FIG. 10, N is updated.
As shown in the figure, a new station is designated. However, when M = 1 is not satisfied, the routine proceeds to step 27f, where it is checked whether or not the mode is M = 3 (timetable set mode), and when M = 3, the correction digit is shifted at step 27g. This step 27g will be described later.

Fig. 13 shows the treatment of switch S ₂ (Fig. 9, step 26g)
Is shown. In step 29a, it is judged whether or not M = 1 (timetable display mode), and if it is MP1, in step 29b,
Preset 3 to M to enter timetable set mode. Then, in step 29c, it is determined whether or not the station name and time data of the station designated by the selection storage unit N exist. If it exists, the flag R is set to 0, and the time data of the address stored in the address storage unit F ₃ (the lower I display unit in the display) is set to the correctable state in step 29e. , Make the display blink. On the other hand, if neither the station name nor the time data exists in step 29c, the station name 1 in step 29f
The digit is set to the correctable state and the flag R is set to 1. That is, in this embodiment, it is possible to set the time of a new station by operating the switch S ₂ , or to change the station data that has already been set. It will be described again with reference to FIG. FIG. 14A is a display state diagram in the timetable display mode, and the rest is a display in the timetable set mode. OS as shown in Fig. 14B
AKA station is selected and specified, and time data is displayed. However, when the switch S ₂ is operated in the state of FIG. 14B, the mode is changed by steps 29a and 29b, and at step 29c, the data exists at the designated station (OSAKA). Therefore, the data (45 minutes) in the lower row I is blinked and can be corrected by step 29e as shown in FIG. 14C. However, when setting new station data, switch S _{1 in} the mode of M = 1 as described above.
Is operated to select a storage area in which no station data is stored, for example, a storage area 22h of the RAM 6 as shown in FIG. 14D. When the switch S ₂ is operated in the state of FIG. 14D, the process proceeds from step 29c to 29f of FIG. 13, so that it is possible to set from the station name and the first digit of the station name is changed as shown in FIG. 14E. Flashes.

In FIG. 14C, the station name and time already set may be changed. In such a case, it is sufficient to operate the switch S ₂ again in the state of FIG. 14C, that is, it is determined in step 29h that the timetable set mode is M = 3, and then in step 29i, R = 0 is determined. That is, since R is set to 0 at step 29d by the operation of the first switch S ₂ , the second switch S ₂
In step 29i, it is judged that it is the second time at step 29i. Therefore, the program proceeds to steps 29f and 29g, and the first digit of the station name can be corrected and displayed as shown in FIG. 14F. However, after the first digit of the station or the lower I data of the time data can be corrected in this manner, the switch S ₃ corrects or sets the value as described later, and the step 27 shown in FIG.
The shift digit is shifted by the switch S ₁ as shown in g. The station name and time data display for M = 3 described above are performed at steps 28h and 28i in FIG. However, as will be described later, when the correction or setting is performed by the switch S ₃ , the flag R is preset to 1. Therefore, after correction or setting, switch S ₂
When is operated, this operation advances to step 29j,
Edit processing is performed. This editing process is a process of changing the set time data in order of earliest time. And then excisional In step 29h the address of the next time data in the current time in the register F ₁ to F _4, to 1 the value of M at step 29l. Therefore, as shown in FIG. 14G, when the switch S ₂ is operated after all the time is set, the editing display, that is, SET is displayed as shown in FIG. 14H, and the last digit is from A to Z. The display is repeated, and when editing is completed, Fig. 14I
As shown in, the mode becomes M = 1 and the time in the timetable next to the current time is displayed.

FIG. 15, step 26h of Figure 9 shows the S ₃ process. In steps 30a and 30b, it is determined whether the mode is M = 0 or M = 1. If M = 0, step 30c sets M = 1. If M = 1, step 30d sets M = 0. This is a process of switching between the current timetable time mode and the timetable display mode. However, in step 30e, it is determined whether or not the timetable set mode is M = 3, and if M = 3, the flag R is set to 1 in step 30f and the correction digit is incremented by 1 in step 30g as described above. Do.

Here, the correction of the time data will be described in detail with reference to FIGS. 14C, K, L, M and FIG.

As described above, when the switch S ₂ is operated with M = 2, if the data of the timetable exists, the lower I display portion blinks as shown in FIG. 14C, and the correction becomes possible. This is the same as explained in step 29e of FIG. However, in this state, the correction can be made by the switch S ₃ , and this processing is executed at step 30g in FIG.

In this case, in the step 30, the first operation of the switch S ₃ is detected, and the data of the address storage unit F ₂ (23 minutes on the display ... Upper II display unit) is incremented by 1 to the address storage unit F ₃ ( Preset to the lower I display). That is, as shown in FIG. 14K, 24 minutes obtained by adding 1 minute to 23 minutes is displayed on the display section of the lower stage I. Then, in the second and subsequent switch operations, this value is sequentially incremented by +1. That is, since the time data of the timetable is set from the early minute data, it is possible to set from the time of one or more previous time data. This operation is performed only when the time unit of the immediately previous time data is the same as the correction time unit.

However, for example, by operating switch S ₃ sequentially from 24 minutes
When the switch S ₁ is operated after setting the minute data for 51 minutes, the time data of the address stored in the register memory F ₄ by the processing of step 27g in FIG. 10 (lower stage II in the display).
Can be corrected (Fig. 14L). Switch in this state
When S ₃ is operated, as described above, the +1 operation can be sequentially performed from 52 minutes which is +1 to 51 minutes which is the previous minute data. However, when newly adding the next time data, the switch S ₁ is operated. As a result, the previously set 51 minutes and 58 minutes are shifted to the upper row and a blank display is made on the lower row at the same time unit and on the lower row I (Fig. 14M), whereby the same time is at 12:00. If the data of the car can be set, and if a new setting is not necessary, the switch S ₁ is operated again to display the next time data which has already been set, for example, the data of the 13:00 table.

When new time data is set in sequence, the storage area for the time data at that station is fully used, and when new time data cannot be set, the FULL display is displayed as shown in Fig. 20, The switch operation of switches S ₁ and S ₃ is invalid.

FIG. 16 shows the S ₄ process of FIG. 9, step 26i. First, in step 31a, it is determined whether or not M = 1 (timetable display mode). If M = 1, proceed to step 31b and set M to 4. M = 4 is a set mode of a mark to ride, and is a mode in which desired time data for which an alarm sound is to be emitted is selected and set. FIG. 17 shows a display state of M = 1 and a display state of M = 4. However,
For example, if switch S ₄ is operated while the timetable of TOKYO is being displayed (Fig. 17A), the desired mark set mode (No.
17 (FIG. 17B), and in step 31c the address storage unit F ₁ ,
The contents of F ₂ , F ₃ and F ₄ are cleared and blank display is performed as shown in FIG. 17C. Then, as will be described later, by operating the switch SA, the time data of TOKYO is sequentially set to F ₁ and displayed as shown in FIGS.
Operate the S ₄ switch again when 11:25 is displayed. The operation of the S ₄ switch at M = 4 is judged at step 31d in FIG. 16, the process proceeds to step 31e, and the 11:25 address is set in the mark address storage unit F ₀ of the RAM 6. Further, at step 31f, the address storage unit four times data from excisional been time addresses F ₀ F ₁ to F ₄
Then, 31g of M becomes 1. Incidentally, M =
Display when the 4 is intended to be performed in step 28j of FIG. 11 are stored in the station name display unit T-ALM indicating the alarm excisional timetable, the display unit of the lower I to the address of the register F ₁ The time of day (which changes sequentially depending on switch S ₄ ) is displayed. However, when returning to the mode of M = 1,
As shown in Fig. 17F, 11:00 when the mark you want to ride is set.
The following four times including the time of 25 minutes are displayed,
The time designation display near 11:25 is displayed. Thus, in the timetable display mode of M = 1, it is possible to know which time the mark to ride is set.

FIG. 18 shows the S ₅ process of FIG. 9 step 26j.
First, in step 32a, it is judged whether M = 1 or not, and M
If = 1, all station name data and time data of the timetable selected in step 32b are cleared, and step 32
Set M to 3 with c and select the first digit of the station name with step 32d to enable new setting. That is, as shown in FIG. 14B, when switch S ₅ is operated when M = 1 and the OSAKA timetable is selected, all station name and time data of OSAKA are cleared, and FIG. 14E is displayed. As shown, setting is possible from the first digit of the station name. Thereby, the time and station name data of the already registered station timetable can be cleared and a new timetable can be set. However, in step 32a of FIG. 18, when M = 1 is not satisfied, M is obtained in step 32e.
= 2 is determined. When M = 2, that is, when the switch S ₅ is operated while the time of the timetable closest to the current time is displayed by the operation of the switch SA, as will be described later, the step 32 is performed. M = 0 is set, and the mode returns to the current time display mode.

FIG. 19 shows details of the SA processing in step 26h of FIG. First, in step 33a, it is judged whether or not M = 0. When the switch SA is operated in the current time display mode with M = 0, among the time data of the timetable selected in step 33b, the addresses of the four time data closest to the current time are the address storage unit. The values are stored in F ₁ , F ₂ , F ₃ , and F ₄ , respectively, and M is set to 2 in the next step 33c. M is 2
As a result, the steps 28f, 2 of the display processing of FIG.
As shown in FIG. 8g, when M = 2 in the display process, the station name and the time data stored in the addresses of the address storage units F _{1 to} F ₄ are displayed. Nearest to the current time 10:50:35 as shown in E
Time data of TOKYO station at 10:56, 11:13, and 25 is displayed. The switch for returning from the mode of M = 2 to the mode of M = 0 is the switch S _{5 as} described above.

However, if M = 0 in step 33a in FIG. 19, it is determined in step 33d whether M = 1 (timetable display mode). When M = 1, step 33e
Then, the time of the timetable displayed on the lower I and II display portions is shifted to the upper stage, and the next time data is newly set and displayed on the lower stage. 12C to 12K show this display state. In the mode of M = 1, when the station is selected by the switch S ₁ as described above, the station name and the remaining number are displayed for 2 seconds. After that, four pieces of time data next to the current time are displayed (for example, FIG. 12C). However, when the switch SA is operated in this state, as shown in FIG. 12D, 11:36 and 45 minutes on the upper stage disappear, and instead 11:52 on the lower stage is displayed on the upper stage. Then, in the lower part, the next time data, 12:30 and 34 minutes, are displayed. In this way, by operating the switch SA, it is possible to display all the time data of the station. Incidentally, for example
In the timetable of OSAKA station, if there is an even number of time data in the 11 o'clock range, as shown in FIG.
Hours 45 and 56 are displayed on the same line, but
Instead of displaying the time data at 12:00, display the analysis at 11:00 and blank. And switch SA
When the blank display at 11:00 is as shown in FIG. 12G by the operation of, the time data of the next 12:00 is displayed at the bottom. If the time data is an odd number, for example,
As shown in FIG. 12I, the horizontal display at 11:31 in the upper row is blank, and in such a case, the next 12 o'clock time data is displayed in the lower row. In addition, as shown in Fig. 12J, between the one day break, that is, between the 23:00 and 0:00 hours.
As shown in K, one line of blank display is provided. In addition, for example, when the start of the timetable is at 5 o'clock and the end is at 2 o'clock, the blank display of this one line is 1
The user may set the blank display of the line.

However, as described above, different blank display is performed depending on whether the time data of minutes in each hour unit is even or odd, for the following reason.

That is, as described in the setting mode of OSAKA station in FIG. 14, each time the switch S ₁ is operated, the setting or correction digit is selected. This is the lower I display section and the II display section. It is an alternate repetition of. Therefore, when the time data is an odd number, additional minute unit data can be set in the blank of II in the lower row, and further, by operating the switch S ₁ , as shown in FIG. 14M.
Since blank display for the same hour unit is made, further minute data for that hour unit can be added. However, when the minute time data is an even number, the time data of the next hour unit is displayed in the lower row unless the minute blank display is provided in the same hour unit as in the above-described embodiment. This is because it is not possible to set additional minute data in the same hour unit.
In order to determine whether the minute data is an even number or an odd number, although not shown, for example, in the storage area of each time unit of the RAM 6, 1
A bit judgment storage unit is provided, and the one bit is alternately rewritten to 0 and 1 each time the minute data is stored or the setting digit is selected by the switch S ₁ at the time of data setting. It is only necessary to store an even number or an odd number, and in the display processing, it is determined whether the blank display of the same time unit is to be performed on the lower display unit when the 1 bit is 0 or 1, and the determination is executed. It is a thing.

However, returning to FIG. 19, if M = 1 is not satisfied in step 33d, the process proceeds to step 33f, and it is determined whether or not M = 3 (timetable set mode). When M = 3, the process proceeds to step 33g and the time zone (hour unit) change processing is performed. That is, as shown in FIG. 14G, when the switch S ₂ is operated from the M = 1 mode, M = 3, and
The digit of the station name is selected by switch S ₁ and the character of the station name is set by switch S ₃ (Fig. 14, E, N, Q). And then switch
When S ₁ is operated, lower stage I flashes and switch S ₃
This allows the minute data to be set (Fig. 14R). If the switch S ₁ is operated after setting 15 minutes as minute data, the lower stage II will flash as shown in FIG.
The minute data set is made by S ₃ (T in FIG. 14). Next, when the switch S ₁ is operated, a blank display is made in the same time unit (0 o'clock) and the next minute data can be set.

The minute data of the thus desired time units and switch S ₁
After setting with S ₃ and operating switch SA,
14 As shown in Fig. V, a blank display is made for the next hour (1:00). At this time, the minute data can be set by the switch S ₁ and the switch S _{3 as} described above. Thus, M =
In 3, the switch SA functions as a switch that changes the time unit of the time data to be set.

However, when it is determined in step 33f in FIG. 19 that M = 3 is not satisfied, the routine proceeds to step 33h, where it is determined whether M = 4. When M = 4 (mark set to ride), the switch SA functions as a switch for sequentially displaying time data on I in the lower row, as described with reference to FIG. 17, and the step 33i performs this processing.

In addition, although the example applied to the electronic wrist watch has been described in the above embodiment, it can be applied to other devices, such as a small electronic calculator and an IC card, and of course, it can be a dedicated device for the timetable. is there. Further, in the above embodiment, the timetable of the station is described, but it is also possible to use it for a timetable of an airplane, a ship, a bus, etc. Further, not only as a timetable but also as a time data storage for schedule management. It can also be used as a device. For example, the schedule time of each person is stored (in this case, the time data is stored including the date), and the person who has an errand is specified and If you set the required time from the schedule, you will be notified when the time approaches.

Further, although the designated station name is displayed in the above embodiment, it may be displayed in abbreviated form by numbers, symbols, etc. Also, if a plurality of address storage units F ₀ are provided, the time at which an alarm will be issued will occur. It is possible to set multiple selections.

Further, the alarm may be displayed instead of the sound, and further, the notification may be made not only for 30 minutes but also before the time set by the user.
