Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a station information display board that displays information such as the destination of an approaching train to passengers.

A control method for displaying train destinations that performs local consistent control at each major station, centering on one major station, without performing individual control at each station or centralized control over the entire line, and This is related to the device.

Conventionally, as a method of controlling a train destination display board for providing guidance to a single passenger, a device using either a centralized control method or a station-independent control method has been used. FIG. 1 is a block diagram showing an example of the configuration of a control system of a centralized control system, in which 1-1 is a central information processing unit, 1-2 is a central unit, and i! Central equipment for transmission equipment such as train centralized control (abbreviated as 0'TO) equipment that connects the train to Stations 1-5(a) at Station A of the same transmission device each represent a guide display board.

B station......N station also has the same facilities as A station arranged as shown. The information display panel 1-5 at each station normally determines the contents and timing to be displayed at each station based on train position information obtained by another means by the central information processing unit 1-1 and internally stored train information. death,
Central equipment 1-2. and a guidance display control device 1-4 that stores guidance display information sent via the station equipment 1-3.
controlled by

In the above method, the information display boards 1-5 at each station are controlled based on instructions from the central information processing unit 1-1, so if the central information processing unit 1-1 malfunctions, the entire guide display board will not be displayed. becomes incapable. Also: J\ Since the central information processing unit 1-1 is complicated and expensive, it is installed on the information display panel 1 as part of the train operation management system.
-5 control has an equipment effect, but if the purpose is only to control the guidance display, it becomes excessive equipment, and there is a separation point that does not necessarily correspond to the actual situation.

Figure 2 is a block diagram showing an example of the configuration of the station independent control method.
2-1 is a relay interlocking device or train position detection device, 2-2
2-3 is a device that serves as a display content information source that provides the content to be displayed on a guidance display board such as a preset board or an on-board train number reading device, and 2-3 is a guidance display board that obtains information from 2-1 and 2-2. A control device that controls 2-4 is installed at a station where guidance is displayed, and provides train approach information from 2-1 and display contents from 2-2 to the control device 2-3. The control device 2-3 converts the timing and drive signal format for driving the guide display panel 2-4 to display information on the display panel 2-4. Currently, destination display devices using this method are widely used, but the display range at each station is narrow and the display starts when a train enters the area covered by relay interlocking device 2-1. The display for approaching trains starts late.

This system has drawbacks such as the inability to notify passengers of a train that has changed destinations before it enters the assigned section.

As stated in the header of the present invention, the information display boards at several stations before and after a major station are locally and consistently controlled at the major station, and the information display boards at several stations before and after a major station are controlled locally and throughout the entire section. In addition to preventing the occurrence of a situation in which it is impossible to display each station, it is also possible to change the destination of an approaching train to two types before the train enters the area covered by one station, as seen in the station-independent control system. The purpose of this system is to improve the guidance service for passengers by using a control method that eliminates the disadvantage of not being able to display the display and the position of approaching trains outside the station coverage area, and to provide the device on a small scale and at a low price. This is what I did.

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

Next, the operation of the apparatus according to this method will be explained using FIGS. 3 and 9. However, changes to the train's destination or type due to train breakdowns, etc. will be made at intermediate stations (
For example, B, c, D.

It is assumed that the test will not be carried out at stations such as E9, but will be carried out at major stations such as A or F stations.

First, let us take as an example a case where a guide display for a train T traveling from A station to F station is to be performed. When a train number is set for the direction of F station on the train T on the A station platform, the number is read by the train number reader 3-2(a),
The station information processing device 13-3(a) displays the two types of destinations of train A on the information display board 3-'4(a) at station 0, and the information is obtained from the train position detection device 3-1(a). The location information and destination 2 type information of train T are displayed on the information display board 3- of B and C stations.
4(b), ' 3-4(c) and provide guidance. If a turn-around train at A station is on the A station platform on track L2 on the opposite side of the track where train T at A station is on the track, if a train heading toward F station is on the train of each train, The station information processing device 3-3 (a) determines the first departure train in the order in which the numbers are set, and displays the information on the information display board 3-4 (a) at each station.
), 3-4 (b).

In 3-4(C), the first departure information is added to the first destination type information and displayed.

When train T departs from station A, train position detection device 3-1
Departure information from (a) is received by the station information processing device 3-3 (a), and from this processing device 3-3 (a), the destination information of the train is sent to the station information processing device 3-3 (f) of station F. 9 types and train position information are sent, and processing device display panel 3-4 (d)
, 3-4(e), 3-4(f), and 3-4(g), respectively. At this time, information display board 3-
4(a) is erased by the station information processing device 3-3(a). If there is a next train on the A station platform of track L2, this train will be moved forward and displayed as the first train.

As train T progresses from station A to station B, the train position changes, but the train position detection device 3 depends on how detailed the train position is displayed on the information display boards at each station B and C.
-1' Based on the train position information from (a), the station information processing device 3-3 (a) arbitrarily selects the guide display board 3-4 of each station B and C.
The output can be displayed in (b) and 3-4 (C). Furthermore, when train T departs from A station, by sending train T information to F station, even if train T changes its destination or type while it is stopping at A station, the latest information when it departs from A station will be displayed. is sent to F station, there is no need to input change information into the station information processing device 3-3(f) at F station. For stations B and O, when changing at station A, the details of the change will be displayed immediately on the information display board 3-4.
(b), sent to 3-4(c) and displayed.

When train T departs from station B, information display board 3-4(b)
The display contents of train T are erased, and when departing from C station, the display on the guide display panel 3-4 (C) is similarly erased, but these erasures are controlled by the information processing device 3 at A station. −3(a
) is carried out by

In addition, the display control for each station is performed by the information processing device 3-3 at station F.
(f), the display contents at this point are displayed based on the information sent from the information processing device 3-3(a) to 3-3(f).

When train T advances from the control range Sl of station A and enters the control range S2 of station F, the train position displays at stations D, B, F, and C are detected by the train position detection device 3-'1 (f). Displayed according to the information provided. Next.

When train T arrives at F station, train T will stop at the arrival platform of F station.
Read the train number with the train number reader 3-2 (f),
This is input to the station information processing device 3'-3<f), that is, as the input information (b) in FIG. 7, to the storage circuit 4-
2. The input information (a) in the same figure is for 1 train T.
When departs from A station.

It is transmitted from station A and has already been stored in the storage circuit 4-1.

When the train number from onboard is stored in the memory circuit 4-2,
When the code checking circuit 4-5 determines that the train number information is correct by a method such as a parity test, the code checking circuit 4-5 issues a verification command to the comparison circuit 4-3. The comparison circuit 4-3 compares and collates the stored information of the storage circuits 4-1 and 4-2, and if the information of both matches, the switching circuit 4-4
A command is given to the switching circuit 4-4 to make the information stored in the memory circuit 4-1 the output information (c), and when there is a mismatch, a command to make the information in the memory circuit 4-2 the output information (c) is given to the switching circuit 4-4. It is applied to the switching circuit 4-4. Also, when the code checking circuit 4-5 determines that the information in the storage circuit 4-2 is incorrect.

If the information (b) is not input even when the train T arrives at the F station platform, it is assumed that the train number reading device 3-2 (f) is malfunctioning, and the comparison circuit 4-3 uses the memory circuit 4- 1
A command is given to the switching circuit 4-4 to adopt this information.

As described above, the output information (c) has highly reliable information content, and after 1 train T arrives at station F, the output information (c) is used to control the information display board 3-4 (r) at its own station. Train T
When departing from F station, the output information (c) is transmitted to the information display board 3-3-4() at the station ahead.

When the comparison by the comparison circuit 4-3 does not match, the memory circuit 4-
Prioritizing the information in 2 means that the arriving train has a vehicle breakdown,
Or, when the on-board train number is changed due to a change in service due to a disruption in the timetable, etc., this is done to make the guidance display such as one line ahead correspond to the newly published train number.

If this is not possible, until the 6th train T arrives from A station to F station, the information display board 3-4 will be unable to display the 9 types of destinations and the message "Adjusting" will be displayed. When the train arrives at F station, the train number reading information at F station is displayed for stations after F station based on the train number reading information at F station. Thereafter, as the train progresses, the information display panels 3-4 at each station are controlled in the same manner as described above.

In addition, if train T is to turn around in the A section direction at F station, the destination display for F station will display "F section" and when the onboard setting device is changed to the train number for A section at F station. , will be displayed changed to Shingyo Hikari.

At this time, the station information processing device 3-4 of F station displays the destination after turning back in advance on the information display board 3-4(f) of F station.
This can be done by changing the logic of the destination information in step (f). In case of turning back at F station.

Needless to say, the display of two destinations, two train positions, etc. is not performed for stations after Station G. When moving a train from F station in direction A, use the same method as above to move the train to F station.
E based on information from the station.

Guides are displayed for stations D, C, and B, and the display at station A is similar to the turnaround operation at station F.

Station information processing devices 3-3(a) and 3-3(f) for A station and F station
) Information transmission between each destination as a type of information.

The location of the two types of trains and the operation number are added if necessary, but since the information is about 30 pieces of information per one way, the purpose can be achieved at low cost with a simple circuit if the actual line transmission is performed using relay contact transmission.

As described in the above embodiments, (1) the present invention controls the information display boards of each station within the control range using a station information processing device installed at a major station, and transmits the information to stations at other major stations adjacent to the control range. By transmitting the information to the information processing device, guidance for a train approaching several stations ahead of one train can be displayed at the station ahead of the train, and destination information that has been changed can be automatically corrected and displayed. In addition, because train numbers are read anew at each major station, it is unlikely that all sections will not be displayed. Furthermore, information transmission between station information processing devices between major stations can be carried out through relay contacts, so compared to large-scale centralized control systems, almost the same effect can be obtained at a much lower cost. This method has many advantages, such as being able to avoid the inability to display all sections, which is the biggest drawback of the centralized control method.
