Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway vehicle operation support display device for providing a driver with various operating information necessary for operating a railway vehicle.

[0002]

2. Description of the Related Art As means for smoothly operating railway vehicles, there is a large amount of information such as speed control by various signals, speed limitation determined by curve conditions, and stop stations determined by vehicle operation.

Among various signals, in the case of a signal displayed on the ground, even if there is a certain distance, it is possible to visually check the operating conditions taken from the position of the signal, so that it is possible to keep in mind in advance. I didn't get caught up in the signal.

However, when the signal becomes an ATC signal of an on-board display system instead of a ground display method, a speed limit suddenly appears, and the vehicle automatically decelerates, but it is difficult to know where the speed limit section is in advance. It was unknown. However, in the case of the ATC signal, a certain speed limit is given, and it is only necessary that the speed becomes equal to or lower than the speed limit.

On the other hand, the ATS- which has recently been adopted in railway vehicles
The P device does not simply display the maximum speed stepwise like the ATC device, but when a signal from the ground is received, the deceleration pattern that considers the deceleration capability of various vehicles as necessary according to the instructions from the ground on the vehicle. When the speed at which the deceleration pattern is set and the speed of the vehicle at that point are caught in the deceleration pattern, the brake will be applied automatically.

FIG. 11 shows an example of a method of displaying a deceleration pattern provided by a conventional ATS-P device, in which the vertical axis represents the vehicle speed 38, the horizontal axis represents the distance 41, and 39.
Indicates the maximum caution speed, and 40 indicates the maximum speed (absolute speed). This figure is a quadratic curve that connects the maximum speed to the distance that is usually drawn, and the distance and speed of the own vehicle should be plotted in this figure to see how the own vehicle approaches this deceleration pattern. Is indicated by.

[0007]

Even if such a deceleration pattern is presented to the driver, since it has nothing to do with the forward vision as seen from the driver, a diagram like that shown in FIG. 11 is presented to the driver. However, it is limited to an indicator placed on or immediately next to the driver's cab, and it is difficult to constantly request confirmation from the driver.

Further, in FIG. 11, the maximum speed 40 changes depending on the position (point) of the vehicle, so that it is difficult to indicate a specific speed on the speedometer as in the ATC device, and the speed is reduced in advance. It is extremely difficult to predict how close the pattern will be or how many seconds later the deceleration pattern will be contacted and the brake applied. For this reason, when the driver is driving the vehicle, the driver suddenly gets caught in the deceleration pattern and suddenly brakes to stop.

This is especially true when the driver is unprepared for the fact that the vehicle suddenly bumps into the deceleration pattern in a situation where a vehicle running like the ATS-P system cannot predict and suddenly acts. May occur, which is very unfavorable. Therefore, it is desired to develop a technique that can predict this and control the speed of the vehicle in advance.

According to the present invention, when operating a railway vehicle, the vehicle side judges the speed limit at which the vehicle should operate, or the conditions required for the vehicle to operate the vehicle with respect to a fixed point on the route, and the driver is informed.

[0027]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of the present invention, which is composed of a position detection means P, an input means I, a memory M, a control means C, a drive means DR, and a display means DY.

The input means I inputs the route conditions of the railway vehicle and the operation conditions of the schedule data, and the memory M stores the route conditions of the railway vehicle, the schedule data and the like. Position detecting means P
Inputs the operating conditions such as route conditions and timetable data, and detects the current position of the vehicle. The display means DY is for displaying operation information necessary for driving the vehicle, and uses a head-up display or a graphic display. The drive means DR outputs a signal for driving the display means DY.

The control means C displays the parking lot on the display means DY in a substantially rectangular shape, calculates the current position of the vehicle detected by the position detection means P and the distance to the parking lot, and calculates the calculated distance. The display means DY is adapted to change the width dimension of the figure in accordance with the above, and to narrow the width dimension when the distance is long by the perspective method and to widen the width dimension when the distance is short.
And the operation information other than the stop is displayed on the display means DY close to or over the graphic.

FIG. 2 is a diagram showing the concept of the operation support information display device according to the present invention, and this composition will be described below. 1 is a vehicle, 2 is an operation support indicator main body, and 3 is an indicator for a driver of information based on the judgment result.
Reference numeral 4 denotes an input device of vehicle operation information, which uses information stored in an IC card or the like, for example, whether the operation of the vehicle is stopped at each station or an express train and what the schedule is like. Reference numeral 5 has a function of detecting the power running status, the brake status, etc. of the controller by the driving information. Reference numeral 6 is a fixed point detection device provided on the upper side of the vehicle, 7 is a detection device provided on the ground side for detecting specific position information, 8 is a wheel, and 9 is a rotation distance of the wheel 8 from the rotation. The odometer for judging is shown. Reference numeral 10 denotes a door opening / closing information detection device, and 11 denotes a driver.

Next, FIG. 3 shows an example of the driving information presented on the display device 3. The display device 3 uses a head-up display or a computer graphic display so as to be projected at a position at infinity ahead of the route. FIG. 3A shows that it is possible to reach the stop, for example, Omiya station, in 3 minutes (3 minutes) in relation to the remaining speed based on the information on the distance and position on the vehicle.

FIG. 3B shows that 2.30 min (2.
It can be reached in 3 minutes), and FIG. 3B shows that it is closer to the stop (the distance to the stop is shorter) compared to FIG. 3A. In the figure, reference numeral 12 represents a stop display, which is considered to be a wall that cannot be crossed, and the width becomes wider as it gets closer. The vehicle speed display 13 at that time is displayed in the stop display 12, and 14 shows the current speed 15 with respect to the arrival time at the stop. 25 shows the stop name.

Next, referring to FIGS. 4 (a) and 4 (b), in FIG. 4 (a), for example, at Takasaki station, 80 km / h
Although approaching at h, the stop display shown at 12b has a hole in the wall. I promise that this is a sign that there is a stop, but that this stop can go through. Here, the display 14 of the time until arrival as shown in the upper right is shown, but this may be displayed by the distance to the stop.

However, there is controversy as to whether it should be displayed by the time to reach or by the distance, and even if you know the distance, you may arrive in a blink of an eye because of your own vehicle speed. Since it is a function of vehicle speed,
It is necessary to judge which is better by the judgment of the user. A method of outputting information to a driver in vehicle operation according to the present invention will be described.

Information such as the distance along the route on which the vehicle operates, the layout of stations, the layout of curves, etc., is entered in advance in the driving support indicator 2, or an IC card brought by the driver 11 for input. Keep it in memory. This vehicle 1
If you set the position of which line at a certain fixed point, such as when you stop at a station, you should be able to find the position on the line based on the information such as the pulse counter on the odometer 9 attached to the wheel 8. It can be known in the driving support display 2 that there is.

However, since the odometer 9 is judged by multiplying the diameter of the wheel 8 by the number of revolutions, the wheel diameter depends on the wheel diameter when the vehicle 1 has finished maintenance and when it has run to some extent. Accurate calculation of distance is not possible because the wheel itself may change and wheels may slip and slide.

In order to solve this problem, the fixed point detection device 7
(Ground elements) are arranged at appropriate intervals, the fixed points are corrected by the fixed point detection device 6, and the accumulated error of the distance calculated from the rotation speed of the wheels 8 is corrected. Here, when the fixed point is out of order due to the rotational speed of the wheel, it is possible to backcalculate how much the wheel diameter should be.Therefore, backcalculate and correct the wheel diameter when this backcalculation value is repeated several times. You can also

Here, when the vehicle 1 approaches a stop up to a certain distance, the distance information such as the station input to the vehicle 1 and the distance data counted by the vehicle 1 side and accurately corrected every time a fixed point is passed. It is shown by a computer graphic that the vehicle approaches the stop using. At this time, the stop name of this station is extracted and displayed at the same time as the distance information. It shows how many minutes or how many kilometers it will take to reach this stop and at the same time displays the current speed. Here, when the stop is displayed, the operation information of the vehicle is input to the vehicle by the IC card brought by the driver, so it is determined whether the stop or the pass should be made at this stop. If the vehicle is to be stopped at this point, as shown in FIG. 3 (a) or (b), it is assumed that there is a wall that cannot pass through, the width is narrow at a distance, and a wide wall is displayed as it approaches. When the vehicle 1 comes closer to the point where the brake must be applied, an alarm bell or the like is used to inform the driver from the ear that the information is displayed.

As a stop display device that is actually in operation at present, a method adopted on the Saikyo Line or Keiyo Line, for example, is known and displayed according to the driver's cab selection speed condition, door condition, and brake handling condition. Some have been considered so that the lighting of the lights and the sounding of the alarm sounds are made, but the lighting of the indicator lights and the sounding of the alarm sounds are activated only when a certain distance from the station is passed, and the fixed point The driver has no way of knowing whether it will work before reaching.

If the approaching stop is a passing stop, the stop is displayed as a stop. The wall is shown in FIG. 3 (a).
Or, it is displayed in the same manner as in FIG. 3 (b), but there is a hole in the wall as shown in FIG. 4 (a) or 4 (b), and it is a stop, but this stop can be passed. Shows.

In the display of this stop, the vertical dimension is set to a constant height, in which it is narrow when the distance to the stop is long, and when it is close, it is displayed in a wide width, and the width of the display of computer graphics to the driver. It is displayed so that you can judge how far you are just by looking at.

Here, when a service brake that is generally used at a fixed distance from the stop is applied and a position slightly ahead of the position where the vehicle can stop at a fixed point of the stop is reached, a voice or chime is displayed in addition to the computer graphics display.・ By giving a caution such as a buzzer that this stop is a stop station, the driver 11 is warned when he is not looking at the graphics display. As described above, according to this embodiment, it is possible to convey the following meaning to the driver by displaying the graphics. (1) It can be determined that the vehicle is approaching the stop soon after it is located far away from the stop. (2) It becomes possible to know what the name of the next stop is. (3) Whether the next stop is a stop or a passage can be judged at a considerable distance.

(4) If it is possible to determine the name of the stop and the time to reach that point, it is possible to automatically determine whether it is too early or late compared to the operational schedule entered by the driver using an IC card or the like. It will be possible.

If various effects can be obtained as described above, it is necessary to confirm to what extent a vehicle stopped at a conventional stop has continuously approached the contents notified by a buzzer or the like when approaching a certain distance. Is possible. Here, as another embodiment of the present invention, a case where a curve speed limit is displayed will be described.

FIGS. 5 (a), 5 (b) and 5 (c) show a second embodiment of the present invention, which finds a stop if the distance is known and the ground information is known. It is possible to know that there is a curve in the same way as. Since the curve generally requires a speed limit for the vehicle, it is given as a kind of speed command signal.

Here, while the speed of the host vehicle is indicated by the arrow 13 in the center, a curve radius of 26, for example, R400
The value of the speed limit 27 (for example, 70 km / h) 27 indicates that if the speed is not reduced further, the wall of the speed limit 27 is hit. In addition, since the display 14 on the right side shows how many minutes should be run while keeping the current speed, for example, 80 km / h, the speed limit 16, 161, 162 is displayed. You can judge whether it is good or not.

Here, even if two or three curves appear in succession, if the speed limit 27 is higher than the frontmost one, it cannot be seen because it is hidden behind the frontmost one. However, when it is more severe than the front one, the wall width is displayed narrow because it is far, but there is a more severe speed limit 27 than the front curve speed limit. The speed limit of the curve indicated by 162 disappears after passing, and the next speed limit appears. Therefore, if the next speed limit 27 is not satisfied at that time, it is free to accelerate the train.

In this way, when the speed limit by the curve is displayed on the computer graphic display, it is possible to visually recognize the curve and the speed limit corresponding to the curve such as at night or on a snowy day, which is represented by a sign on the ground. It becomes extremely difficult, but it becomes extremely easy to know how much position the curve is and what the speed limit is.

The patterns of FIGS. 3 (a) and 3 (b) and FIG. 4 (a),
There is no problem in displaying (b) and the speed limit of this curve in an overlapping manner. That is, in FIGS. 3 (a) and 3 (b), if there is a speed limit due to a curve in front of the stop, a speed limit wall having a large width appears because it is closer to the stop wall. If the speed limit wall is far from the stop, this car will stop at the stop, so it is not a problem in the invisible state. When you stop at the stop and leave, the wall that indicates the stop is gone, so you can see the speed limit due to the curve.

In the case of a passing station as shown in FIGS. 4 (a) and 4 (b), the position of the next speed limit is determined through the window on the wall as to what the speed limit of the curve on the side opposite the wall of the stop is. It will be possible to know before passing through what is there.

Next, FIG. 6 will be described. The 13 arrows indicating the speed state of the own vehicle and the curved speed limit 16 are the same as those described with reference to FIG. 5, but an open arrow indicated by 18 is shown below. The length of the bar in the center of the arrow indicates the distance to the railroad crossing. When the railroad crossing display 18 approaches, the length of the open arrow bar increases, indicating that the distance to the railroad crossing is approaching. When there is no problem at the railroad crossing, this arrow gradually becomes larger and passes through, but if the vehicle becomes inconvenient at the railroad crossing, it becomes necessary to stop the vehicle immediately. In such an emergency, the driver of the car operates the emergency alert installed on the railroad crossing.

Alternatively, a foreign matter detection mechanism attached to the railroad crossing detects that a foreign matter such as an automobile has stopped inside the railroad crossing, and an emergency alert is issued. In this case, if the car is run as it is, there is a possibility that the car may come into contact with the vehicle at the level crossing, so it is necessary to stop before this level crossing.

Stopping at this railroad crossing extends a wall with a width equal to the length of the shaft upward from above the shaft of the open arrow. The appearance of this wall and the width of the wall make it possible to know the position of the railroad crossing where the emergency alarm was issued. However, it is necessary to inform that a matter requesting an urgent stop has appeared audibly by a buzzer or a chime that informs that an emergency alert has been issued to a railroad crossing. This relationship is as shown at 19 in FIG.

Next, the railroad crossing display 20 in FIG. 8 shows a display when a plurality of open arrows are overlapped and displayed. There are three railroad crossings at the distance A, the distance B, and the distance C, respectively. Is shown. If there is an emergency alert at a railroad crossing of distance B among the three railroad crossings displayed here, it is displayed as if the wall of width B rises.

In the above embodiment, it is described that the wall exists at the position corresponding to the point where it must stop, and it stops so as not to hit the wall. It is required to stop at, and considering the position of the deceleration pattern, the driver is required to make a difficult judgment.

Here, as proposed in the specification of Japanese Patent Application No. 3-259472, speed / distance pattern until deceleration or stopping to an appropriate speed when there is a stop, a speed limit on a curve, or an emergency alert at a railroad crossing. And think about what the deceleration pattern looks like and display it. According to this display, what kind of deceleration should be done at what time is automatically displayed.Therefore, the vehicle decelerates too fast, or the vehicle overruns the stop point due to delayed braking. Can be prevented.

FIG. 9 shows the shape of the wall when the vehicle is stopped at a stop in consideration of a deceleration pattern, and the deceleration pattern corresponding to a curve, the deceleration pattern of a railroad crossing, etc. can be displayed in exactly the same manner. is there.

FIG. 10 shows a third embodiment of the present invention. If three of the correct time, the correct position, and the scheduled operation schedule are available, how many minutes this vehicle deviates from the scheduled operation schedule. It is possible to judge very easily. If driving is performed according to the operation schedule regardless of delay or early arrival, it is considered that the arrival time at the stop will show the difference between the current position and the time as it is, so the delay or early arrival time will be stopped. It can be displayed as a delay or early arrival.

In general, the time lag on the timetable can be given in the form of what time and what time it should pass or depart from the stop, so if you arrive early next to the name of the stop, you will see that it is wrong. If it is delayed by the downward triangle, it can be sufficiently expressed by displaying how many minutes it is shifted from the downward triangle.

One of the methods is to display these on the screen as a computer graphic display to the driver, but if it is possible to notify the driver by projecting the display on the route ahead like a head-up display. It is possible to provide a highly reliable display with less possibility of oversight.

According to the above-described embodiment, since the stop point, the curb speed limit, the level crossing display, etc. can all be displayed by the same expression method as the stop point and the speed limit, it is highly possible that a driver overlooks the mistake. It is possible to provide a low signal to the driver. In addition, since it is fundamental to know your position and the exact time, if you compare it with the operating schedule of your own car, which is entered with an IC card, how much is your car deviating from the operating schedule? Since it can be displayed together with the display of the station, it can be very easily judged whether the driver arrives early or late for the timetable of his own car, which requires the most head, and it is very easy for the driver to operate the navigator. You can expect it.

If there is an LCX or the like on the side of the road and each vehicle sends the position information of its own vehicle and other vehicles can catch the information, what will happen to the preceding vehicle from the current position of the own vehicle. It becomes possible to know what. Since this preceding vehicle must not have a rear-end collision, it is considered that a red signal is emitted at that position, and the wall in the present invention exists. However, in general, information about such preceding vehicles is ATC, ATS, ATS
In most cases, it is not necessary to transmit it as the information of the preceding vehicle because it is translated and transmitted by various signals of -P. Therefore, the preceding vehicle information is not required except when the signal of the moving block system is used.

Even if the stop signal is blue at each stop, if there are many routes, the number of the line to enter is determined by the timetable of the own vehicle, etc., so the accessible line is displayed on the screen. Things can be done easily. However, when the schedule is disturbed or special operation is performed, it is necessary to transmit the instruction at the station to each train by information transmission means such as radio or LCX, but the means for transmitting is outside the scope of the present invention. ,
If possible, the latest information shall be displayed on the vehicle cab.

There are other items such as accident information that require judgment as to whether or not the driver can continue driving, and this may be considered as a judgment item by the driver or the like and not directly related to the present invention.
