Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an on-board operation display device for a railway vehicle, and particularly to an on-board operation display device for a railway vehicle, and in particular, it is possible to display a sufficient operation display on a train even if the amount of data transmitted from a ground control system to the vehicle is small. It relates to a device that allows the above to be carried out.

[Background of the invention]

Conventionally, in railway systems, most of the information provided from the ground side to the operators of vehicles in operation has been limited to information indicating whether or not the own vehicle can enter the approach route, such as from traffic lights, for example.

For this reason, if there is a change in the predetermined operation plan, there is a risk that the driver will feel anxious and suffer a heavy mental burden.

For this reason, if it is possible to know the approach route of the track and the location of other vehicles on the train, even if there is a change in the operation plan, there will be no mental burden on the driver, and safety will be improved. Operation can be ensured.

By the way, in order to provide the driver with such information for vehicle operation, an operation display device is installed on the vehicle, which displays a route map for a predetermined range in the direction of travel from the position of the own vehicle, and a display for that area. What is necessary is to display the approach route of the own vehicle and the positions of other vehicles there.

However, in order to display such a display, a huge amount of data must be transmitted from the ground side to the vehicle side. The problem was that it would be difficult to implement because it would be expensive.

[Purpose of the invention]

The present invention was made in view of the above problems, and its purpose is to require a relatively small amount of data to be transmitted from the ground side to the vehicle side, and to be able to display sufficient operation information at low cost. An object of the present invention is to provide an on-board display device for displaying vehicle operation information.

[Summary of the invention]

In order to achieve this objective, the present invention divides a route on which a vehicle operates into a plurality of sections, stores data for displaying a route map for each section in advance and holds it on the vehicle, and Among the data necessary for displaying operation information, the above-mentioned route map data is characterized in that it is only necessary to transmit data regarding which of them to select.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle display device for vehicle operation information according to the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing a ground side system according to an embodiment of the present invention, in which 1 is a vehicle position detection device, 2 is a control device, 3A to 3N are transmission devices on the ground side, and 4 is a receiving device on the vehicle side. It is. Note that 5 represents a vehicle.

Further, FIG. 2 shows an embodiment of a system on the vehicle side, in which 6 is a processing device, 7 is a storage device, and 8 is a display device.

The vehicle position detection device 1 functions to detect where a plurality of vehicles are located on a predetermined route using data obtained from a train signal track circuit, a CTC device, and the like.

The control device 2 tracks the vehicles (plurality) on a predetermined route using the data from the vehicle position detection device 1 and controls the route, and is composed of a computer or the like. be. Note that these devices are well known and are used in train operation management systems and the like.

The transmission devices 3A to 3N are for transmitting data from the control device 2 to the vehicle 5, and are composed of, for example, a guidance radio device, and are installed at predetermined points along the route.

The receiving device 4 functions to receive data from the transmitting devices 3A to 3N.
Corresponding to N, it is constituted by, for example, an inductive radio device.

The processing device 6 operates based on data received from the ground side via the receiving device 4, processes the data, controls reading of the data from the storage device 7, and displays the data on the display device 8. It is composed of, for example, a microcomputer.

The storage device 7 functions to divide the route on which the vehicle 5 operates into predetermined sections and store data for displaying the route map for each section as a basic route map image. It consists of a large amount of memory.

The display device 8 is for displaying operation information as an image, and is composed of, for example, a liquid crystal display panel, and is installed in a place easily visible to the driver, such as the driver's seat of the vehicle 5.

Next, an example of the operation information displayed on the display device 8 will be explained with reference to FIG.

This example shows a case where the present invention is applied to a railway within a steelworks, and is displayed after the vehicle 5 has passed a specific point, for example, a point where the transmission device 3A is installed, and the track is connected to two products. Processing plants 12 and 1
It shows that the line is branched into three lines each going into the middle of the road. The position of the vehicle on the line is indicated by a figure in which automatic vehicle 5 is filled in, and other vehicles 9
is displayed as a white outline. Further, the approach route of the host vehicle 5 is shown by a filled-in track 10, and the route that cannot be entered is shown by a white track 11.

Therefore, the driver of the vehicle 5 can accurately know the operation information for a predetermined range including his own vehicle, so that he can operate the vehicle with peace of mind.

Next, the processing device 6 on the vehicle side in this embodiment
The operation will be explained with reference to the flowchart of FIG.

When the vehicle 5 departs and starts traveling, the system becomes operational and the vehicle 5 transmits the transmission devices 3A to 3A.
Every time one of the 3N passes through a certain point, the processing device 6 performs processing according to the flowchart of FIG.

When it is detected in step that one of the transmission devices 3A to 3N has passed a point where it is installed, it is checked in step whether or not that point is the basic screen update point. This is due to the following reason. That is, the basic route map to be stored as data in the storage device 7 and displayed on the display device 8 is one that shows the route along which the vehicle 5 is operated, divided into predetermined sections. is necessary. The selection of which of these basic route maps should be displayed is made depending on which of the transmission devices 3A to 3N the vehicle 5 has passed through. On the other hand, this display switching of the basic route map is performed only at points where the vehicle 5 passes through the transmission devices 3A to 3N, but it is not necessarily performed at all points of these transmission devices 3A to 3N. This is because multiple transmission devices 3A to 3N may be installed within a section represented by the same basic route map, and in this case, the basic route map is selected only at the first point of the same section. This is because all you have to do is

When the result in step is YES, that is, the point where any of the transmission devices 3A to 3N that you just passed was installed is the closest point in the section represented on a certain basic route map. If so, the process advances to step 100, where the basic route map screen number set inside the transmission device is fetched from the receiving device 4, and in the next step, the basic route map image data of the corresponding number is read from the storage device 7.

Meanwhile, during this time as well, the ground-side control device 2 creates an operation plan based on the vehicle position detection device 1.
The approach route of the vehicle 5 is determined based on this operation plan.

Therefore, in the next step, the processing device 6 takes in the data representing this approach route via one of the transmission devices 3A to 3N and the receiving device 4, and in the next step, it fills in the tracks on the basic route map screen. Write by.

In the step, data representing the position of the vehicle that has passed the point where the transmission device is currently installed, that is, the own vehicle 5, is acquired from the control device 2, and then in the step, data representing the current position of the vehicle 5 on the line is retrieved from the control device 2. Data representing the position of other vehicles within the indicated section is imported. Then, in step 10, the line position of each vehicle is written on the basic route map screen. At this time, as explained in FIG. 3, the own vehicle 5 is written in a filled state, and the other vehicle 9 is written in a white state.

Finally, in step 11, all data is given to the display device 8 to rewrite the displayed image. Therefore, on the display surface of the display device 8,
For example, an image as shown in FIG. 3 will be displayed.

On the other hand, as already explained, the transmission devices 3A to 3
When passing a point where one of the N is installed, there are cases where that point is a point that does not require changes to the basic route map, and at such a point, the result of the step will be NO.

Therefore, in this case, proceed to the step after the step, and there is a possibility that a situation that requires changing the approach route may have occurred between the time when the system passed the transmission point immediately before the transmission point that it has just passed and the present time. Please take this into consideration and check accordingly. If the result in this step is YES, the data representing the new approach route will be transmitted from the ground side control device 2 to the processing device 6, so this will be processed in the step and the basic route map screen will be displayed in the step. Write. Then, from this step through step 11,
As already explained, the display device 8 displays the information.

Also, if the result in the step is NO,
Proceed directly to the step and the display will be performed in the same manner as above.

Therefore, according to this embodiment, the transmission devices 3A-
Every time the vehicle 5 passes a point where a 3N is installed, a basic route map is selected that outlines the layout of the tracks in a predetermined section from that point in the direction of travel, and the map is selected based on the latest data at that time. One of the refreshes of the vehicle location information within the section is performed, and the operation information can be displayed on the display device 8 installed in the driver's seat of the vehicle 5 or the like.

According to this embodiment, the data for displaying the basic route map image, which requires an enormous amount of data, is stored in advance in the storage device of the vehicle, and in order to display the basic route image, the data is simply stored. Since it is only necessary to transmit the data to decide whether to display one of the two from the ground side to the vehicle side, there is no need to worry about the amount of data to be transmitted becoming enormous, and it is possible to operate the vehicle at low cost. Information can be displayed.

Next, FIG. 5 shows another example of the operation information displayed on the display device 8, and is shown for example in cases where a sufficient visibility of the track is not obtained, such as in an underground railway. And point A
For example, a transmission device 3A (Fig. 1) is installed in the
Therefore, this basic route map will be displayed when the host vehicle 5 passes point A. Furthermore, at this moment, when the host vehicle 5 passes point B,
For example, a transmission device 3B is installed at this point B, and as a result, the basic route map is not refreshed at point B (if the result in the step in Figure 4 is NO), and the approach route is changed. In this case, a new approach route will be displayed, and the current position of the vehicle, including the vehicle itself, will be displayed.

Now, suppose that on the track shown in FIG. 5, the normal approach route of the vehicle 5 is the track 11'. However, at this time, it is assumed that the operating condition is disturbed for some reason and another vehicle 9' is on the track 11', and therefore the vehicle 5 is instructed to take the track 10' as the approach route. In this case, if the driver of the vehicle 5 was only given information on whether or not the vehicle 5 can enter, as has been the case in the past, then under the current situation where the other vehicle 9' in front cannot be seen, Therefore, the driver does not understand why the approach route was changed, causing great anxiety and increasing mental burden. However, according to this embodiment, if the operation display as shown in FIG. It is easy for drivers to understand, there is no need to worry about giving them any sense of anxiety, and it can lighten their mental burden.

As is clear from the above description, the display device according to the present invention is limited to those whose display images are relatively simple and have a limited pattern as shown in FIG. 3 or FIG. 5, for example. Therefore, it is not necessarily necessary to use a relatively high-class display method such as a dot matrix display, and even if a relatively low-cost display method with a limited display area for each rough part is used, it is sufficient to achieve the purpose. can be achieved. However, if it can be used in common with display devices such as various monitor devices that have been increasingly used in recent years, it can be implemented without any cost problems even if high-grade devices are used.

In addition, in the present invention, the vehicle position detection device and control device on the ground side can be used in common with various operating pipeline systems and safety systems such as existing CTC devices, and in this aspect as well, it is possible to significantly reduce costs. .

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to display operation information on the vehicle while keeping the amount of data transmitted from the ground side to the vehicle side to a minimum, thereby overcoming the drawbacks of the conventional technology. A vehicle that provides accurate operation management status to the driver while driving the vehicle, and allows the driver to drive appropriately with an emphasis on safety at all times without increasing anxiety or mental burden. An on-board display device for operation information can be provided at low cost.
