Simultaneously, it receives data representing the existing line position of its own train 5, the existing line position of other train 9 and the entrance line of the train 5, solidly coates the position and the entrance line 10 of the train 5, and displays the position of the train 9 in a blanked state.

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 relates to an on-board operation display device for a railway vehicle, and particularly to a system for displaying sufficient operation information even when the amount of data transmitted from a ground control system to the vehicle is small. Concerning a device that can be accessed in a car.

[Background of the invention]

Conventionally, in railway systems, most of the information given to drivers of vehicles in operation from the ground side has been limited to information indicating whether or not the vehicle can approach the approach route, such as from traffic lights. Therefore, if there is a change in the predetermined operation plan, the driver may feel anxious and the thickness may place a mental burden on the driver.

If it is possible to know the track approach route and the location of other vehicles on the train, even if there is a change in the operation plan and there is a hole, the driver will not be mentally burdened and completely lost. Safe 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 and displays a route map within a predetermined range in the direction of travel from the position of the own vehicle, and information on the route. What is necessary is to display the approach route of the own vehicle and the positions of other vehicles on the route.

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

[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 the entire route on which the vehicle is operated into a plurality of sections, and stores data for displaying the entire route map for each section in advance and holds it on the vehicle. Of the data necessary for displaying vehicle operation information, the above-mentioned route map data is unique 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 in an embodiment of the present invention, where ■ is a vehicle position detection device, 2 is a control device, 3A to 3N are ground side transmission devices, and 4 is a vehicle side receiving device. It is. 5 represents a vehicle.

ifc, FIG. 2 is an example showing a system on the vehicle side,
6 is a processing device, 7 is a storage device, and 8 is a display device.

A vehicle position detection device 1 detects where vehicles (plurality) are located on a predetermined route using track circuits for train signals, CTC
〇The control device 2 works to detect based on data from devices etc. The control device 2 detects vehicles (multiple) on a predetermined route.
This device tracks the train using data from the vehicle position detection device 1 and controls the route, etc. It is composed of computers, etc. These devices are used in train operation management systems, etc. This is a well-known fact.

The transmission devices fff3A to 3N are large devices that transmit 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>3N, and is constructed of, for example, a guided radio device corresponding to the transmitting devices 3A to 3N.

The processing device 6 operates based on data received from the ground side via the receiving device 4, processes the data, and stores the data in the storage device 7.
It functions to control the reading of data from the computer and display it on the display device 8, and is constructed of, for example, a microcomputer, and is large in size.

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

The display device 8 is a sixth device that displays 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 after the vehicle 5 has passed all the points where the transmission device 3A is installed, for example, the display is broken and the track is connected to two places. It shows a state where the lines are branched into three lines each going into product processing plants 12 and 13. The position of the vehicle on the line is indicated by the self-vehicle 5 being filled in and shown in a six-dot shape, and the other vehicles 9 being displayed in white. 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 operation information for a predetermined range including his own vehicle, and can operate the vehicle with peace of mind.

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

When the vehicle 5 departs and starts traveling, the system is not ready for operation, and each time the vehicle 5 passes a point where one of the transmission devices 3A to 3N is installed, the flowchart shown in FIG. The processing is performed by the processing device 6.

When it is detected in step (2) that one of the transmission devices 3A to 3N is installed and passes a certain point, it is checked in step (2) whether or not that point is a 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 divided into predetermined sections along the route on which the vehicle 5 is operated. 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 is installed and which point the vehicle 5 passes through. On the other hand, the display switching of this basic route map is carried out by the vehicle 5 using the transmission device 3.
However, it is not necessarily carried out at all points of these transmission devices 3A to 3N.

This is because some of the transmission devices 3A to 3N may be installed multiple times within a section represented by the same basic route map, and in this case, only the first point of the same section is This is because all you have to do is make a selection.

When the result in step ① is YES, the six points where any of the transmission devices 3A to 3N that have just passed are installed are the closest points in the section represented by the basic route map. If there is, proceed to step ①, import the basic route drawing number set inside the transmission device from the receiving device 4, and then transfer it to the storage device 7 in the next step ②.
The basic route map image data plan reading page of the corresponding number.

Meanwhile, during this time as well, the control device 2 on the ground side creates a complete operation plan based on the information from the vehicle position detection device 1, and determines the approach route of the vehicle 5 based on this operation plan.

Therefore, the processing device 6 performs the following processing as the next step (■).
Data representing this approach route is taken in via one of the transmitting devices 3A to 3N and the receiving device 4, and in the following step (2), it is written on the basic route drawing to fill in the lines.

In step (2), data is acquired from the control device 2 that indicates the position of the six vehicles that have passed through the point where the transmission device is currently installed, and the current position of the own vehicle (5). Data indicating the location of other vehicles within the section represented by the selected basic route map is imported. Then, in the process of step σ, the line position of each vehicle is written on the basic route drawing. At this time, as explained in FIG. 3, the own vehicle 5 is written in a filled-in state, and the other vehicle 9 is written in a white state.

Finally, in step α, all the data is given to the display device 8, and the displayed image is rewritten. Therefore,
For example, an image as shown in FIG. 3 is often displayed on the display surface of the display device 8.

On the other hand, as already explained, the transmission equipment fff 3 A~3
When one of the N is installed and passes a certain point, that point may be a difficult point that requires a change in the basic route map, and at such a point, the result in step ① will be NO.

Therefore, in this case, after step ■, proceed to step ■, pass all the transmission points immediately before the transmission point you just passed, and it is possible that a situation has occurred that requires changing the approach route between 6 hours and the present. Please take into consideration the fact that there is a difference in the quality of the product and perform checks accordingly. If the result in step (2) is YES, the data representing the various approach routes will be transmitted from the ground side control device 2 to the processing device 6. is displayed.

If the result of step (2) is No, the process directly proceeds to step (2) and the display is performed in the same manner as above.

Therefore, according to this embodiment, when the vehicle 5 passes a certain point where the transmission devices 3A to 3N are installed, the layout of the tracks in a predetermined section from that point in the direction of travel is schematically shown in the six basic route maps. Either the selection or the refreshing of the train location information of the vehicle in that section based on the latest data at that time is performed, and the operation information can be displayed on the display device 8 installed in the driver's seat of the vehicle 5. It will be done.

According to this embodiment, the larger data for displaying the basic route map image, which requires an enormous amount of data, is stored in advance in the storage device 7 on the vehicle side. Sixth, the sixth data that determines which of them to display is simply transmitted from the ground side to the vehicle side. Sixth, there is no risk that the amount of data to be transmitted will become enormous, and it is low cost. Operation information can be displayed on the vehicle.

Next, FIG. 5 shows another example of the operation information displayed on the display device 8, and is an example of a case where the line of sight cannot be seen sufficiently, such as in an underground railway. . Then, at point A, for example, transmission device 3A (first
Figure) The basic route map will be displayed when the car 5 has passed point A.

Furthermore, at this point in time, when the own vehicle 5 passes point B, for example, a transmission device 3B is installed at this point B.
As a result, the basic route map is not refreshed at point B (if the result in step In addition, the line position including the own vehicle at this point will be displayed. Now, on the main route shown in Fig. 5, the approach route for vehicle 50 in normal times is track 1.
Suppose that it is 1'. However, at this time, due to some reason, the train operation status was disrupted, and another vehicle 9 was present on track 11', so vehicle 5 was instructed to take track 10' as its approach route. 0 In this case, conventional force) et al.
If the driver of vehicle 5 had only been given information on whether or not the vehicle could enter, as has been said, then this driver would have been unable to see the other vehicle 9' in front of him. For the soldiers, they don't understand why the approach route was changed, and the dogs cause anxiety and increase their mental burden. However, according to this embodiment, if the operation display as shown in FIG. The display device of the present invention can be easily understood by the driver, does not cause any sense of anxiety, and can reduce the mental burden. If the displayed image is, for example, the third
As shown in Figure 5, it is relatively simple and is limited to six patterns, so relatively sophisticated display methods such as Todd matrix display are not necessarily necessary, and large Even if a relatively low-cost device with a limited display area for each small portion is used, the purpose can be sufficiently 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 is possible to implement it without any problem in terms of cost even if a standard one is used.

In the present invention, the vehicle position detection device and control device on the ground side can be used in common with the existing CTC device system and the safety system, and it is possible to significantly reduce costs in this aspect as well. 0 [Moving bed 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. By eliminating the shortcomings of the conventional technology, we can provide the driver with accurate operation management status while driving the vehicle, and always emphasize safety without increasing anxiety or mental burden. It is possible to provide an on-vehicle display device for vehicle operation information that enables accurate driving at a low cost.
