Abstract

PURPOSE:To enable a passenger to easily confirm the arrival time of his/her train at a destination station, and the timetable of a train be changed at a junction station, using his/her own cardsize terminal. CONSTITUTION:A data transmission master station 100 sends the radio signals of data preliminarily stored in a memory section via an antenna 110 on a train, regarding timetable information on the train and other timetable information on a train to be changed on the same line as the present train, or another line at a junction station. On the other hand, a passenger receives the radio signals from the antenna 110, and converts the signals into original timetable information, using his/her own data receiving terminal 200. The converted data is saved in the terminal 200, and timetable information for the next station, timetable information at a station for disembarkation or a change, and other information are caused to be shown on a display section 206, via the selective operation of the terminal 200. According to this system, a passenger can obtain desired timetable information, whenever necessary, while staying on board.

Description

[Detailed description of the invention]

[Object of the invention]

0002

[Industrial Application Field] This invention receives timetable information sent into the train by a data receiving terminal owned by a passenger on the train, and selects and finds the timetable information necessary for the passenger. This invention relates to a time display/guidance device capable of providing time display and guidance.

0003

[Prior Art] Conventionally, such a device has not existed, and passengers can tell when the train they are boarding will arrive at the station where they are scheduled to get off, when it will arrive at the station where they are scheduled to transfer, and how long they will spend there. If you want to know whether you can transfer to a connecting train if you wait, check the timetable in booklet format in advance, or check the timetable bulletin board installed on the platform or concourse of the connecting train at the connecting station. I needed to.

0004

[Problem to be solved by the invention] In this way, conventionally,
If you want to know timetable information, such as what time a passenger will arrive at the station you plan to get off at, or what time you will arrive at the station you plan to transfer to, and how much time you have to board a connecting train, you should check the timetable magazine. Alternatively, it was necessary to look at the timetable bulletin board installed at the station, but this had the following problems.

[0005] In other words, when a passenger is boarding a train for the first time, he or she may be worried about what time the train he or she has boarded will arrive at his or her destination station, or whether the train has already passed his or her destination station. It is something that haunts me. for that,
The departure and arrival information announcements inside the train also announce the arrival time of the next stop, but since I'm not used to hearing it,
If you are not paying close attention, you will often miss what you hear, and you will not necessarily be able to get enough information from the in-car guidance announcements.

[0006]Also, even if you know the name of a station when you stop at a station en route, you may not be able to clearly understand the context of the station you are planning to get off at, so you may wonder how long it will take you to arrive until the announcement is made. It is accompanied by a sense of tension. As a result, passengers are not provided with sufficient information regarding train timetables onboard the train, which creates a sense of anxiety and tension, especially when using the train for the first time.

[0007] The present invention was made in view of these conventional problems, and uses a receiving terminal that is small enough for a passenger to hold in his/her hand (so-called electronic notebook size or card calculator size) to allow passengers to receive information about their own ride. By selectively displaying the train's arrival station name and arrival time, as well as the arrival number and scheduled departure time of connecting trains at transfer stations, the necessary timetable information can be obtained at will, reducing passengers' feelings of anxiety and tension. An object of the present invention is to provide a time display/guidance device that can reduce the amount of time.

[Configuration of the invention]

[0009]

[Means for Solving the Problems] The time display and guidance device of the present invention includes a storage section that stores timetable information of trains and timetable information of connecting trains at transfer stations, and a storage section that stores timetable information of trains at transfer stations, and a storage section that sends out the timetable information of the storage section. a data transmitting master station having a data transmitting unit that transmits the data, an antenna that is disposed in the train and transmits the transmitted information from the data transmitting unit as a wireless signal, and a data transmitting master station that receives the wireless signal from the antenna and transmits the original time. A receiving unit converts the timetable information into table information, a storage unit stores the timetable information received by the receiving unit, and selects the timetable information for arriving at the next station and the timetable information for connecting trains at the station where you plan to get off or the station where you plan to transfer. The device is composed of a data receiving terminal having a display section for displaying the data.

0010

[Operation] In the time display/guidance device of the present invention, the data transmitting master station uses the timetable information of the own train stored in advance in the storage unit and the timetable of connecting trains at transfer stations on other lines or on the own line. The information is sent out as a radio signal through an antenna installed inside the train.

[0011] In contrast, the passenger receives the radio signal from the antenna using the data receiving terminal that he or she brings, converts it to the original timetable information, stores it in the storage unit, and selects the next one. By displaying station timetable information, timetable information of scheduled alighting stations, planned transfer stations, etc. on the display section, the desired timetable information can be immediately obtained while remaining on the train.

0012

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 shows the system configuration of an embodiment of the present invention, which includes a data transmitting master station 100 that transmits timetable information of its own train 10 and timetable information of connecting trains at transfer stations; An antenna 110 that converts timetable information from the data transmission master station 100 into a wireless signal and sends it into the train 10, and a data receiving terminal 200 that is the size of a card calculator or electronic notebook that can be carried by passengers. It is made up of. In addition, data transmission master station 1
00 receives switch contact signals from a switch 120 that notifies departure completion, an initial setting switch 121, and a door switch 122.

As shown in FIG. 2, the data transmission master station 100 includes a microprocessor (MPU) 101, a random access memory (RAM) 102, a read only memory (ROM) 103, and switches 120, 121,
22, a transmission interface (transmission IF) 105 for transmitting timetable information data to each antenna 110, and a calendar circuit 106.

The MPU 101 reads the program written in the ROM 103 step by step,
It is an arithmetic processing unit that performs program processing by decoding and decoding the instruction part and executing the instruction. The configuration of the program executed by this MPU 101 is to set the start address of the timetable table (described later according to FIGS. 5 to 7) in the initial setting, and to import an external signal every time a train completes leaving the station. It has a departure pointer that updates the first address to the next address, and a function that periodically sends out timetable information through internal processing of the program.

The RAM 102 stores intermediate results processed by the MPU 101, external input information such as departure completion and first departure settings, data such as pointer values and timetable information to be sent to the transmission buffer, and other related data for processing. temporarily,
or to remember continuously. Moreover, the ROM 103 is an MP
U101 stores in advance a group of commands and timetable information for carrying out the above-mentioned program processing.

The input interface 104 issues an interrupt when a change occurs in the switch signal input from the departure completion switch 120 or other switch signal input handled by the crew, and the MPU 101 detects the interrupt destination and stores the interrupt destination in advance. Read the start address of the program being executed and execute the program starting from this address sequentially.
Let it run.

Furthermore, the transmission interface 105
Through program processing, data such as timetable information is loaded into an internal buffer in units of 1 data (8 bits), converted into a serial code and turned into an on/off signal for each bit, which is then modulated using the FM method etc. death,
Furthermore, in order to transmit as a weak radio wave signal of spatial waves,
The signal is modulated with a high frequency carrier wave such as 0 MHz and transmitted from the antenna 110.

The calendar circuit 106 is a circuit that performs calendar calculations to determine whether the day is a weekday, a holiday, or a Saturday, and selects timetable information corresponding to that day.

The data receiving terminal 200 is shown in FIGS. 3 and 4.
As shown, MPU201, RAM202, ROM2
03, an input interface 204, a reception interface 205, a display section 206, a driver circuit 207, an operation section 208, an antenna section 209, and a power supply section 210.

[0021] The MPU 201 is connected to the data transmission master station 10.
Similar to the MPU 101 on the 0 side, the program is processed by reading the program written in the ROM 203 step by step, decoding and decoding the instruction part, and executing the instruction.

The RAM 202 stores processing results during program execution, input data from the operation unit 208, data transmitted by the data transmission master station 100, and data to be displayed on the display unit 206. Also, ROM
203 stores a processing program for operating the operation unit 208 or reading data received from the reception interface 205.

[0023] The input interface 204 is connected to the operation unit 2.
When the push button 08 is pressed and an interrupt occurs, the interrupt destination is detected, the start address of the program to be executed is read, and the program starting from this address is executed sequentially.

Furthermore, the reception interface 205
The high frequency carrier wave modulation signal received by the antenna 209 and sent out from the antenna 110 is input, the carrier wave signal is removed, the FM modulation signal etc. are separated, demodulated, the on/off signal is extracted, and the signal is converted into an 8-bit parallel signal and built in. At the same time, an interrupt signal is generated and the MP
Give to U201. Then, the MPU 201 is made to sequentially execute a program starting from the interrupt destination address, and to take out in parallel the 8-bit signal that was set in the buffer earlier.

As shown in detail in FIG. 4, the display unit 206 displays the arrival station name, scheduled arrival time, presence or absence of a connecting station, destination of the connecting station, scheduled departure time, arrival number, vehicle type, etc. In order to display the information on the display unit 206, a decoder function for converting and displaying the characters and numbers into human-readable characters and numbers is performed by program processing. The driver circuit 207 is for controlling the display on the display unit 206, and outputs the signal in accordance with the signal level of the display device.

Next, the operation of the train display and guide device having the above configuration will be explained.

<<Transmission of timetable information>> The data transmission master station 100 periodically (eg, every minute) generates an internal interrupt to execute a program. If the first train is set, this program will calculate the minutes from address 0 (first departure station) to the last station of the timetable data table T1 of the train you boarded shown in Figure 5, that is, from mark 1 (or mark 2) to mark 2 ( Or the arrival station name, data up to mark 1),
The expected time of arrival and the address in the connecting station column are sequentially read out from the data stored in the ROM 103 by the MPU 101 as a set of data, and sent to the transmission interface 105.

Next, train timetable tables T2 and T for connecting stations shown in FIGS. 6 and 7 starting from address 1 and address 2 in the column of connecting stations included from the first station to the last station are shown.
3 from the first train to the last train in the order of departure time, the departure time, destination, car type, and number are sent as a set of data in address units in the same way.

Then, the arrival of the train 10 at the terminal station is indicated by a 1 or 2 in the mark column of the data table T1 in FIG.
At the same time, it is determined by inputting the on-contact signal of the door switch 122, and if this terminal station becomes the starting station, the timetable table of the train from this starting station to the next terminal station is determined. T1 is sent out, and the same operation is repeated until the final destination station where the mark column becomes 3. In this case as well, if an address is written in the connecting station column of the train timetable table T1 during that time, the timetable table of the train at the connecting station starting from that address is sent in the same way as above. .

<<Update of Departure Pointer>> When the train 10 passes through the platform section, departure is completed, the departure completion switch 120 inputs an on-contact signal, and the departure pointer is updated by one. The value of this departure pointer has a one-to-one relationship with the arrival station name.
The relationship between In addition, train 1 existing at the starting station
0 does not mean that the departure is complete, so when the initial setting button switch 121 is pressed and an on signal is input, the departure pointer is reset to 0.

<<Display of timetable information>> When the data receiving terminal 200 receives a carrier wave signal in the train, the power supply section 21
0 is turned on and ready to receive data. Then, the data transmitting master station 100 receives the signal transmitted via the antenna 110 via the antenna unit 209, and the RAM 20 receives the signal sent via the antenna 110.
2 is stored in the data table format shown in FIGS. 5 to 7.

[0032] Therefore, when the departure pointer in the data table T1 is updated or the "display" button on the operation unit 208 is pressed, timetable information such as the arrival station name, estimated time of arrival, and connecting station name for the address indicated by the departure pointer is displayed. is the display section 206
will be displayed.

<<Selection of alighting station information>> With the station name of the next arrival station, estimated time of arrival, and presence or absence of connecting stations displayed on the display section 206, by pressing the "Incretion" button, the current departure point will be displayed. The timetable information is displayed on the display unit 206 by incrementing the value indicated by one, and the station to get off at is selected and the estimated time of arrival is displayed.

[0034] If you want to reproduce the display at this station with one touch, write the address of the station you want to get off at on the timetable information pointer and press the "memory" button to save it. It is stored in the RAM 202. In this way, once you memorize it, next time,
By simply pressing the "Remember" button, you will be able to display the estimated time of arrival at your exit station with one touch.

Next, if the station to get off at is a transit station, in order to be able to select the train to transfer to, if "Yes" is displayed in the connecting station column of the display section 206, then "
When you press the "Connect" button, you can select the timetable information of the scheduled departure time of the connecting train that exceeds the scheduled arrival time of the connecting station, and then select the train's destination, scheduled departure time, departure/arrival number,
Displays information on vehicle types such as limited express, express, rapid, semi-express, and ordinary. Here, too, if it is desired to display the timetable information of connecting trains at these transfer stations with one touch, the address of this timetable is saved in the operation pointer by pressing the "memory" button on the operation unit 208.

[0036] If the "display" button is pressed in this manner, the normal display (display of next arrival station name, arrival time, etc.) is restored.

[0037] Note that the ``decrease'' button on the operation unit 208 is used when the ``increment'' button is advanced too far.
This button is used to perform a return operation. In addition, the "Reset" button can be used to move the corresponding operation pointer by -1 by pressing the "Reset" button when the timetable information of the connected station is read and displayed by pressing the "Memory" button.
It is used to set and remove from memory.

[0038] In addition, when selecting a connecting train, since the timetable information of connecting stations is arranged in order of scheduled departure time, it is necessary to distinguish between up and down trains, or when there are multiple connecting trains or tracks. This is done at the operator's discretion. Also,
When selecting a timetable for weekdays, holidays, Saturdays, etc., the calendar circuit 106 built into the data transmission master station 100 automatically selects the timetable for that day.

In this manner, the train display and guidance device of this embodiment allows the data transmitting master station to transmit the timetable information of the own train stored in advance, as well as the connecting stations where transfers can be made on other lines or on the own line. It detects that the own train has departed from the station, and periodically sends out the timetable information of the connecting train by switching the timetable information of the connecting train with the pointer information indicating the timetable information of the next station. Passengers, on the other hand, receive and store this information using the data receiving terminal they bring with them, and based on this received data, they usually display timetable information for the next station and perform selection operations. This allows you to display timetable information for the station you plan to get off at and for connecting trains at connecting stations, allowing you to instantly check the timetable information while still on the train.

[0040]

[Effects of the Invention] As described above, according to the present invention, a passenger can instantly know the scheduled arrival time of his or her alighting station, the name of the next station until the alighting station, and the arrival time using the data receiving terminal. This makes it possible to judge information such as whether the train has not passed the station to get off at, or whether it is approaching the station to get off at, based on the timetable information from the data transmission master station of the train you are riding. There are no mistakes or oversights, unlike when checking by referring to a timetable magazine.
Even if you are using a train for the first time, you will feel less anxious and nervous.

[0041] Furthermore, when a passenger transfers to another train at a disembarkation station, information such as the departure time and platform number of the train he or she wishes to transfer to can be easily found from the scheduled arrival time at the specified disembarkation station. This eliminates the need to check the timetable bulletin board installed in the arrival platform of the connecting train or in the passageway such as the concourse at the station where you get off, making your trip more comfortable.
