Abstract

PURPOSE:To output a possible train time in a departure point and to give the information of an accurate train schedule by retrieving and outputting time data nearest to subsequent time data obtained by adding a necessary time to the departure time among departure time data. CONSTITUTION:A present time is extracted from a clock circuit 12, the discrimination of routes is simultaneously shown and a data retrieval key decides which of a first or second line is selected. In the case of a first route, most earliest and possible train time data is retrieved from time table data in a data memory 4 in accordance with the present time. At that time, the necessary time data to the station of the first route is added to the preset time and the possible departure time is selected. The possible train time in the station 2 is retrieved and displayed by using the earliest departure time of display data in the first route and the necessary time data to the station of the second route. Step retrieval is executed before and behind the time displayed at present in terms of one hour, and the departure time is displayed. Thus, only the possible departure time can automatically be retrieved and displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to electronic equipment, and particularly to electronic equipment that stores vehicle departure time data and searches for and outputs this data.

[Prior Art] Devices that store telephone numbers, addresses, and other data, and search and display them as needed have been known as advanced versions of small electronic devices such as electronic desktop calculators and electronic learning devices. ing. This type of device is also called an electronic notebook, and devices that can store train and bus route timetables have also been proposed.

[Problems to be solved by the invention] Conventional devices that can store timetables check the current time using a clock, etc., and display data close to that time in steps to obtain the desired data. It is nothing more than an electronic version of the traditional timetable written on paper.

For example, when transferring between multiple lines, the user must calculate the time required for the first line or the walking time required to transfer, and then perform the information processing to select the boarding time for the next line. The ease of use of the table itself was not much different from that of conventional timetables, and the problem was that it was difficult to use, requiring more troublesome operations than turning pages.

On the other hand, software for personal computers that uses the train network in the Kubuki region to search for routes that can reach a destination in the shortest time, or small electronic devices equipped with such functions, have been proposed. In this case, the process of simply outputting the average boarding time and total transfer time from a certain station to a station near the destination or a nearby station, or selecting the optimal route based on this is performed.

For this reason, there is a difference in transfer time between mornings and evenings when there are many trains, and daytime and evenings when there are fewer trains.
It is not always possible to reach the destination within the calculated time, and tragedies such as failing to make a connection and missing the last train may occur. In some regions, it can cause severe mental, physical, or economic damage to users. Also, if you are late for a meeting with an important client,
In this case as well, the user will be seriously harmed.

Such information processing technology is useful for estimating how much time it will take to visit a destination for the first time and making a schedule, but it is difficult to use it continuously when commuting. It is not suitable for practical use because it is unable to respond to changes in travel time.

In view of the above problems, it is an object of the present invention to provide an accurate boarding schedule to a destination at any time of day without requiring troublesome information processing on the user's side when storing and outputting timetable data. The goal is to provide electronic devices that can.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides an input means equipped with a numerical data input means, a data search instruction means, and departure timetable data for a predetermined starting point of a transportation route. a first storage area for storing time data required for eight shifts to the starting point; and a second storage area for storing time data required for eight shifts to the starting point; From the time data obtained by adding the departure time data stored in the first storage area to the time data obtained by adding the time required to reach the stored departure point. The present invention employs a configuration that includes means for searching for the closest time data after the search means and a control means for outputting the time data obtained by the search means in a predetermined output method.

[Operation] According to the above configuration, by adding the predetermined time and the time required to reach the starting point, it is possible to output possible boarding times at the starting point.

[Embodiments] The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 shows the structure of the operating surface of an electronic device based on the present invention. Here, you can use the electronic desk calculator to search for timetables.
This shows a device with an integrated display function.

As shown in FIG. 1, a display 1 is arranged above the operation surface. The display device 1 is composed of an LCD panel or the like capable of displaying characters, numbers, etc. of approximately 10 digits x several lines.

A keyboard 2 (encircled by a broken line) is provided at the bottom (front side) of the display 1. The keyboard 2 is provided with the following keys. The keys 21 to 24 are used to move the cursor or to perform step search and display of data in a predetermined search mode.

The timetable key 25 is a key for displaying a timetable.

The key 26 is used as an equal key in the calculator mode, and as a key for specifying data input timing in the timetable mode.

The numeric keypad 27 (the part surrounded by the dashed line) is used for inputting various numerical data and character data.

The data search key 28 is used in the timetable mode to command the output of departure time data.

The key 29 is used to switch the input mode of the numeric keypad 27 between numerical and character input modes.

The key 210 is used to switch the operation mode, and each time the key 210 is pressed, the various operation modes set in the device are sequentially switched.

FIG. 2 shows the structure of the control system of the device shown in FIG. 1.

The display and keyboard in FIG. 1 are indicated by the same reference numerals, and data input/output processing by these is controlled by a control circuit shown in the center of the figure.

The display on the display 1 is controlled via a display decoder/driver 3. Display data is stored in a data memory 4 consisting of a RAM or the like.

The data memory 4 is used as display data and as a work area for calculations by an ALU (arithmetic processing unit) 9. The data memory 4 stores timetable data for a plurality of routes, which will be described later.

On the other hand, the key press data of keyboard 2 is stored in large buffer 7.
Input via . The ALU 9 determines which key is pressed on the keyboard 2 through interrupt processing and the like, and performs the corresponding program processing. In addition, output data such as key scan signals from the keyboard 2 are sent to the keyboard 2 via an output buffer 8.
is output to.

A, L U 9 executes the control procedure described later, and 5
The control procedure is stored as a program in a program memory 5A consisting of a ROM or the like. Instructions inside the program memory 5A are sequentially taken out one by one at the designated addresses by the address decoder 5B, analyzed by the instruction decoder 6, and executed.

Further, in this embodiment, a clock circuit 12 is provided to display the time (clock function) and to use the current time for data processing in the timetable display. Timing by the clock circuit 12 and operation of each control circuit are performed in synchronization with the clock output from the reference signal generating circuit 11. The reference signal is generated using a crystal oscillator or the like.

Each control block above has an address and data bus,
They are connected mainly through a control bus 10 consisting of interrupt signal lines and the like. Each block consists of discrete elements, multiple I
It can be constructed from C, etc., or the whole can be constructed from one chip LSI.
It may be composed of

The basic operation of the above control system is as follows.

When an instruction retrieved from the program memory 5A is executed, for example, the data stored in the data memory 4 is transferred to the AlO2, arithmetic processing is performed, and the result is stored in the data memory 4 again. The data stored in the data memory 4 is displayed on the display 1 via the display decoder/driver 3. Also, in the input processing from the keyboard 2, key data taken from the input buffer is stored in the data memory 4. The AlO2 analyzes this input data, selects and executes the process corresponding to the input key according to the program in the program memory 5A.

In the above configuration, the device performs processing such as normal four arithmetic operations, storing and displaying telephone numbers, and also performs timetable processing as described below.

FIG. 3 shows timetable data stored in the data memory 4. Here, FIG. 3(A) is timetable data for the first route, and FIG. 3(B) is timetable data for the second route. The code H%M is time data and minute data, respectively, and the departure time is expressed by a combination of these data.

In addition, these departure times are for stations on the 1.2 lines (Eki-1, Eki-2), and the time data DRI and DR2 until reaching that station are also stored in the timetable data. . If you board the first line and then transfer to the second line, the time data DRI is the travel time by walking from the current location (for example, the user's company, office, etc.) to the first station, DR2 is the sum of the boarding time and transfer time for the first route.

Note that the order of transfer between the first route and the second route is entered in advance through a predetermined operation when inputting the data.
It is assumed that identification is possible using a flag (not shown) or the like.

Although FIG. 3 shows a format corresponding to a boat fishing timetable, when actually storing data in the data memory 4, the data storage format is not limited to the format shown.

FIG. 4 shows the basic operating procedure and corresponding display results when searching for a timetable using the apparatus shown in FIG.

Here, the current time is 8:16 p.m., and from this time it takes 13 minutes (data DRI in Figure 3) to travel to station 1 (Equi-1) on the first line, and then board the train for 28 minutes. Station 2 (Equi-2) for transfer to the second line in minutes
Assume that you arrive at a destination, ride a train for a predetermined period of time, and then arrive at your destination.

3 (A) and (B) are stored in the data memory 4 in advance.
) is registered, when the timetable key 25 is pressed as shown by numeral 41 in FIG. The display ``Eki-1'' appears on the display 1, indicating that the timetable of . In addition, when the timetable key 25 is pressed again, as indicated by numeral 47, the display 1 shows, as indicated by numeral 51, that the timetable for station 2 on the second line can be searched according to the previously stored transfer order. "Eki-2"
will appear. When key 25 is pressed again, code 44 is displayed.
The display returns to the display indicating that the first route is to be searched.

On the other hand, when the data search key 28 is pressed after the timetable key 25 from the state of code 44, the data DR shown in FIG.
Display 1 indicates the departure time of Station 1, where you can board after the time indicated by I, which is the sum of the travel time to Station 1, as indicated by code 45.
will be displayed.

From this state, if you press the timetable key 25 as indicated by reference numeral 48, you will enter the timetable search for the second route.
If you press the data search key 28, you will board the train at the earliest boarding time (8:39) at station 1, and the data DR in Figure 3 (B), which is the boarding time for route 1, will be displayed.
The departure time at station 2 after the time when 2 is added is displayed as 53. Here, if you can get on the train at Station 1 at 8:39, you will be able to ride for 28 minutes and arrive at Station 2 at 9:07, so data from 9:17 onwards is displayed as the subsequent boarding data.

On the other hand, when the key 22 is pressed from the state 45, boarding data for a later time when boarding is possible at station 1 is displayed as 46, with the current time as the departure time.

Also, when searching for the second route from the state of code 45,
As mentioned above, the calculation is performed using the earliest boarding schedule, but for example, if you want to use the later time of 8:54 displayed with the code 45, the code 50 is used.
Press the key 24 as shown below. As a result, the display changes to display only 54 minutes of data as indicated by reference numeral 54. If the data search is performed based on the earliest time displayed, if you search for the second line with the code 48.49 from this state, the schedule for departing from station 1 at 8:54 will be the same. You can search for departure time data. Although not shown, when a key such as key 21.23 with an arrow pointing in the opposite direction to key 22.24 is pressed, a step search is performed in the opposite direction to the above, that is, the time is set in units of 1 hour or 1 departure time. It is assumed that the display is shifted in units.

FIG. 5 shows a control procedure for the above device. This procedure is stored in the program memory 5A as an ALU executable program.

Step S1 in FIG. 5 is a display process, in which the display data stored in the data memory 4 is displayed on the display 1, and the data to be displayed as 0 is determined by the control described later.

In step S2, key operations on the keyboard 2 are detected.

If there is no key operation, the process returns to step s1 and continues displaying, and if there is a key operation, the process moves to step s3.

In step S3, the type of the operated key is determined, and depending on the result, steps s4 to s6, S10, S16,
The process moves to one of the processes in S18.

For example, when the key 26 is pressed, it is determined that the timetable data is to be registered, and in steps s4 and S5, the data shown in FIGS. 3(A) and 3(B) is
Enter timetable data such as , and register the data in the data memory 4. At this time, the operating method and procedure used in the past are used, and time, station name data, etc. are sequentially registered. Figure 1 shows the display status during registration, and shows the departure time of a certain station (Equi-1) at 8 p.m.
The example shows the state immediately after inputting the hour 45 minutes (PM8-45).

When the timetable data search process shown in FIG. 4 is designated by the key 25, the process moves to step s6. In step S6, flag 1 is checked to determine whether the timetable data for the first route is in the display state.

As a result of this check, if the data for the first route is displayed, the process moves to step S13, where flag 1 is reset,
Subsequently, in step 314, data for the second route is displayed.

On the other hand, if the data for the first route is not displayed, the process proceeds to step S7, where flag 1 is set, and the process proceeds to step S8, where data display processing for the first route is performed.

In steps S8 and S14, display processing indicated by reference numerals 44 and 51 in FIG. 4 is performed. That is, the current time is taken out from the clock circuit 12 and displayed as shown in FIG. 4, and at the same time, "Eki-1" and "Eki-2" are displayed to indicate the route distinction.

As described above, in response to pressing the key 25, the first and second
The selection of routes alternates. At that time, route switching is performed alternately based on the determination of flag 1.

Step S8. After S14, in step s9,
Since the search has not yet been performed, flag 2 indicating this is reset. When you enter search mode, this flag 2
is set. After that, the process returns to step S1, and the display 1
Flag 2, which continues to be displayed, is reset every time a route is selected.

On the other hand, when the data search key 28 is pressed as indicated by reference numeral 42 (or 49) in FIG. 4, the process advances to the search mode after step SIO.

In step S10, flag 2 indicating the search mode is set, and then in step Sll, the state of flag 1 is determined to determine whether the first or second route is selected.

If flag 1 is set and a search for the first route is instructed, the process goes to step S12 for 6 lines, and a search for the first route is performed. At this time, the earliest possible boarding time data according to the current time is is searched from the timetable data in the data memory 4. At this time, as described above, a possible train departure time is selected by adding the data DRI to the current time. Display data is created based on the retrieved data, and display driving is performed in step S1. The display state at this time corresponds to numeral 45 in FIG.

Subsequently, when the key 25 is pressed as indicated by reference numeral 48 in FIG. 4, the route is switched through the processes of steps S6 and S13.

If the data search key 28 is pressed here, the process moves to step S10, and depending on the state of flag 1, step Si
A transition occurs from t to S15, and in this step, the earliest departure time of the display data of the previous first route and Fig. 3 (
Possible boarding times at station 2 are searched using the data DR2 in B), and the process returns to step S1 to display them. Here, the display state is as indicated by reference numeral 53 in FIG.

In the display state of possible departure time data such as 45, 46, 53 in FIG. 4, the search mode is in which flag 2 is set, and the step search described above using keys 21 to 24 is possible.

That is, when keys 21 and 22 are pressed, step 31
If the setting of flag 2 is confirmed in step 6, step search processing as indicated by reference numerals 43 and 46 in FIG. 4 is performed. Here, a step search is performed forward and backward in units of one hour from the currently displayed time, and the departure time is displayed. Further, if keys 23 and 24 are pressed, step 31
If the setting of flag 2 is confirmed in step 8, step search processing as indicated by reference numerals 50 and 52 in FIG. 4 is performed. Here, a step search is performed in the forward/backward direction from the currently displayed time in units of departure times, and the departure times are displayed.

As described above, the clock information of the built-in clock circuit 12 and the pre-stored stations on multiple lines can be used without the need for troublesome data processing or complicated key operations on the user's side as in the past. Using the B shift hours (DRI, DR2), it is possible to automatically search for and display only the available departure times.

According to the above-mentioned embodiment, even if the time zone is different, it is possible to search only for data that allows passengers to board the vehicle, so there is no risk of failing to board the vehicle as in the conventional case.

Further, since a step search using the keys 21 to 24 is possible, it is possible to easily know the possible boarding times before and after that time, and it is possible to consider the possibility of various boarding schedules.

In the above description, the search is performed using the current time measured by the clock circuit 12 as the starting point, but it is also possible to input a desired time and search for possible boarding times from that time.

The search method is not limited to the above, and modifications as shown in FIG. 6 can be considered.

In the above method, since the search is performed after adding up the travel time to each station, the search data has no meaning unless you are at the first point of connection.For example, station 2 in Figure 3 is the terminal station. Therefore, there is a possibility that the passenger may get off there and do some shopping, and at that time, the user may want to know the departure time of the train from Station 2. An operating procedure as shown in FIG. 6 can be considered so that it can be used for such purposes. Here, it is also assumed that timetable data as shown in FIG. 3 has been registered in the data memory 4 in advance.

In the case of FIG. 6, as the data search key 28, 28a
128b are used. Here, data search key 28
The data search key 28a has the same function as the data search key 28, and the data search key 28b is used to set the required time to board the data DRI, DR2, etc. to 0 hours when searching for possible boarding times. .

When the timetable key 25 is pressed as indicated by numeral 61 in FIG. The same search and display as described above is performed as indicated by reference numeral 68 by adding the required time of 13 minutes to the above.

On the other hand, if you have already arrived near station 1 and the time required to board the train is 0, press the data search key 28b while specifying the first route search with code 67.
7, the search is performed without using the data DRI stored as the time required to reach the station. As a result, code 7
9, the departure times from Station 1 after 8:16, which is the current time, are displayed.

After that, like the code 74, use the timetable key 25 to select the code 80.
When the search route is switched as shown in , and the data search key 28a is pressed as shown in 75, in this case, the required time D
R2 is used to search for and display possible departure times at station 2 after adding the required time of 28 minutes for the first route as indicated by reference numeral 81.

On the other hand, if you are currently getting off at Station 2 and can get on the second line in 0 minutes, press the timetable key 25 from the state of 67 to 64, and press the timetable key 25 as shown in 64. Switch the search route as in 70.

Next, when the data search key 28b is pressed as indicated by reference numeral 65, the departure time data for station 2 after the current time can be displayed as indicated by reference numeral 71 without using the required time to station 2 (DR2).

The processing procedure includes a process of calculating the required time data as O when the data search key 28b is pressed in step S12;
In addition to S15, the one shown in FIG. 5 can be used. Further, the data search key 28b does not need to be dedicated, and other function keys, numeric keys, etc. may be used instead.

In the above embodiment, the time required to reach the final destination on the second route is not taken into consideration, but this time is stored as the third required time data and the arrival time at the final destination is calculated. You can.

For example, after searching for the departure time of the first route as shown at 68 in FIG. 6, press the key 25 as shown at 76 and select the search for the second route as shown at 82, and here, Press the data search key 28a as shown in code 77 and press the data search key 28a as shown in code 8.
3, search for and display the departure time of station 2 on the second line.

If the time required to reach the destination station on the second line is stored in advance, when the key 25 is pressed again as indicated by numeral 25, that time will be added (at this time, the time will be added as indicated by numeral 83). (the earliest time is the starting point), and the arrival time at station 3, which is the destination station on the second line, is displayed as 84. This allows you to easily know the arrival time when you ask your family to pick you up at the station.

Furthermore, memorize the time required from Station 3 to your home.
When the key 25 is pressed again as indicated by the symbol 66, the symbol 7 is pressed.
The final arrival time at home (or destination) may be displayed as shown in 2. In this case, you can easily know how much time you have at your destination. For example, the user can easily know the departure time in order to arrive home in time for the night game broadcast on TV.

Further, reference numerals 63 and 69 in FIG. 6 indicate another embodiment. Here, as indicated by reference numeral 68, possible departure times for station 1 obtained by adding the required time to station 1 are searched,
The difference of 10 minutes between the time from the current time 8:16 to the first departure time obtained by searching and the actual required time of 13 minutes is displayed at the bottom of the display 1. This allows the user to know how many minutes they have until their first boarding time, and determine whether they can make a phone call or go shopping during that time.

Above, we have given an example of a case where there is data that allows you to ride in the timetable data, but if you cannot search for data that allows you to ride,
A warning can be generated using the procedure shown in FIG.

After specifying the search for the first route as shown in code 73 using the key 25 as shown in code 71 (current time 11:10 p.m.),
When the data search key 28 (same as in FIGS. 4 and 5) is pressed as indicated by 72, possible boarding times at station 1 are displayed as indicated by 74. Here, if you select the search for the second route using the key 25 as shown at 75 (the display at this time is 77), and press the key 28 as shown at 76, you can select the earliest departure time 11 shown at 74. The required travel time of the first route (DR2) of 28 minutes is added to 11:56 to obtain 11:56. In this case, Figure 3 (
As is clear from B), since there are no flights on the second route, a message 78 indicates that the last train on the second route cannot be taken.

This allows you to easily determine whether you will be able to catch the last train at an earlier stage of your connecting schedule, and at the very least, you can take measures such as arranging accommodation as soon as possible.

In the embodiment shown in FIGS. 6 and 7, the keys 21 to 2 are also
Of course, it is possible to perform a step search using 4.

In the above, display output was exemplified as the output process, but the same technique can be implemented even when performing recording output, output to other equipment, etc. Further, the number of routes is not limited to the above two, and may be any number. Furthermore, it goes without saying that any desired combination of the above-mentioned techniques can be implemented, and that the form of the device is not limited to small electronic devices.

[Effects of the Invention] As is clear from the above, according to the present invention, the input means includes a numerical data input means, a data search instruction means, and a first input means that stores departure timetable data for a predetermined departure point of a transportation route. and a second storage area for storing data on the time required for the six movements to the starting point; Among the departure time data stored in the first storage area, the nearest time data after the time data obtained by adding the time required to the starting point is selected from among the departure time data stored in the first storage area. Since the configuration includes a means for searching time data and a control means for outputting the time data obtained by the search means in a predetermined output method, the predetermined time and the time required to reach the starting point are added. By doing this, possible boarding times at the starting point can be output, and the user can know the accurate boarding schedule according to pre-stored timetable data at any time of day, without the need for troublesome information processing on the user's side. It has an excellent effect.
