Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a device for creating diagrams necessary for train operation, so-called train schedules, and in particular to an automatic train schedule that is effective for creating parallel schedules (diagrams without overtaking). Regarding the creation device.

[Background of the invention]

Traditionally, in order to plan train operations and create timetables,
This work was carried out by people who were experts in train operation, using their intuition based on their experience and handwritten work on a desk.

However, in recent years, a so-called ``train schedule creation system'' has been proposed by the Japanese National Railways, etc., which utilizes the drawing function of a computer and allows the creator to automatically create a schedule by simply inputting predetermined data. has been done.

However, since the systems that have been proposed in the past are versatile and have a wide range of applications, the data that needs to be input is diverse and enormous, and it is difficult to operate the system. However, it has the disadvantage that it is complicated and is not suitable for making relatively simple diamonds such as the parallel diamonds commonly used in underground tunnels.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to reduce the amount of data that needs to be input,
Moreover, it is easy to handle and has sufficient functionality when applied to relatively simple diamond creation such as parallel diamonds! To provide an automatic diamond creation system that allows the planning and creation of diamonds to be carried out easily, quickly, and accurately. This makes it easy to extract various types of data that are essential to managing train operations, such as calculating transportation capacity and distance traveled.

[Summary of the invention]

In order to achieve this objective, the present invention consolidates the drawing function of a computer into a function of drawing multiple needle lines parallel to each other, and allows drawing to be performed by simply specifying the starting and ending positions of these diagonal lines. It is characterized by the fact that

[Embodiments of the Invention] Hereinafter, an automatic timetable creation device according to the present invention will be described in detail with reference to illustrated embodiments.

FIG. 1 shows the overall configuration of an embodiment of the present invention.
In this figure, 1 is a central processing unit such as a computer, 2 is a display device such as a cathode ray tube (CRT), 3 is an operation panel consisting of a keyboard, etc., and 4 is a display device such as a cathode ray tube (CRT).
is a printer, and 5 is a 70-tuppy disk for memory.

The input information in this embodiment can be roughly divided into two types.The first is data that is input and stored in advance in the memory in the central processing unit 1, and this depends on the condition of the track on which the train is operated. It consists of the following data.

1-10 Route configuration of train routes (station names, locations, distances, presence or absence of branches, etc.) 1-21 Train operation conditions (planned running time between each station, stopping time at each station, turnaround time) etc.) The second type of input information is data input via the operation panel 3, which is further divided into control information and specification information. First, the control information includes the following.

2-11 Start and stop calculation of train running trajectory 2-2. Instructing to travel in the opposite direction Next, the specified information includes the following.

2-3. Starting station, destination station 2-4. First departure time 2-51 Train type (regular car, forwarding car, trial run car, etc.) 2-6. Operation head (also called train operation interval, "time interval", etc.) 2-7. Input/output information 2-8, [, Travel route at Shigaeshi Station Next, the operation of this embodiment will be explained.

First, the operator starts up the system and inputs the time period of the timetable to be planned and created from the operation panel 3, and the central processing unit 1 displays the station on the vertical axis and the time on the horizontal axis.
) represents the case corresponding to the route configuration shown in FIG. 2(b), and the line represented by X has not yet been shown. In addition, the figure in Fig. 2(a) has already been
% indicates that another diamond has been previously created and input, and a line due to this is displayed as indicated by Y.

Therefore, in accordance with the timetable to be created, for example, at 9:20, the operator specifies the downward direction from station A on the operation panel 3, and then inputs the control information for starting the train. is the pre-entered data (1- above)
1.1-2 data), the calculation of the train's running trajectory from the specified time 9:20 is started, and it is displayed on the screen S of the display device 2 +ilj! Display as X. At this time, the central processing unit 1 displays the line X as a line that increases from moment to moment as indicated by an arrow, giving the impression that a train is running.

The display in FIG. 2(a) shows a train that departed from station A at 9:20, but since there was no instruction to stop at station B, the train passed through it and headed for station C.

On the other hand, the data (1-1 above) representing the route status shown in Fig. 2(b) is input to the central processing unit 1, and therefore, there is no possibility that there will be a branch in the running track before C station. be informed in advance.

Therefore, the central processing unit 1 calculates the trajectory of the train up to the point before station C, displays it on the screen S as a line X that extends to the point before station C, and then temporarily stops the extension of the gland X. In this way, a question is asked to the person handling the problem in order to instruct the person handling the problem as to which of the branches to proceed.

If the operator responds to this via the operation panel 3 and specifies a certain approach route, the central processing unit 1 will then follow the specified route.
Start calculating the line trajectory j≧ and convert it to b on the screen S
x is displayed sequentially as an extension.〈〈○ At this time, if the operator tries to correct the file because he is aware that there is an error in the running of the train, You can specify reverse travel by using Then, the central processing unit 1 sequentially erases the trajectory of the train that has come so far, and along with this, the line X on the screen S is also erased little by little from the beginning. ,
It shows a situation where the train is moving backwards. This shortening operation continues until the operator inputs a stop command or until the robot returns to the starting point.

Therefore, according to this embodiment, a diamond can be arbitrarily drawn on the display device while looking at the screen S of 2, and the creation of the diamond until the optimum condition is obtained and the editing can be done quickly and easily in an interactive manner. And it can be done accurately.

The data representing the trajectory of the train created and edited in this way is then given to the printer 4, printed out as a train schedule, or stored on the floppy disk 5, and used for other train operations. The number used to load diamonds into the management system.

Also, at this time, if you calculate not only the train schedule, but also the total distance traveled by the train, the hourly transportation capacity, etc., and extract the corresponding data,
This can be useful for accurately formulating transportation plans and vehicle maintenance management plans.

Next, some specific usage examples of this embodiment will be explained.

Example: ' + rfl' Input r711 & From 10 to 9 o'clock, 5 trains will be operated from station B to station A under a 5 minute operation head.'' In this case, the operator enters the above command via the operation panel 3. After inputting this, in response to this, the central processing unit 1 calculates the travel trajectory for five trains starting from station B, according to the travel time and stop time that have been input in advance. . At this time, A
At the station, please turn back according to the designated turn-around route.
When turning back at station B or station A, if it is calculated that the time at which the route arrives at the destination station will be past the specified 9 o'clock, please stop at the station before that. It's Nishide.

In this way, the travel trajectory (diagram) for a total of 9 trains is memorized and printed out, but the display on the screen S at this time is as shown in Figure 3. Example 2.1 Train input In this example, , as already explained in Figure 2, in this case,
The operator first inputs the starting point of the train using the operation panel 3. This starting point is specified by location (starting station) and time (starting time). When the operator confirms this on the screen S of the display device 2 and then inputs the command to start driving, the operator will start the journey according to the travel time and stop time input in advance, as in Example 1. Start calculating the position over time. This situation is shown on screen S
The train's regular trajectory is shown on a graph that shows the position of the train from moment to moment, the vertical axis shows the location, and the horizontal axis shows the flow of time. When the train approaches a branch,
If you input in advance which direction you want to go in, such as in a travel pattern, the car will follow that direction, but if there is no branching direction specified, it will stop there and ask the driver to direct it. Even if there is a turnaround, if that fact is input, the train will proceed in the opposite direction from that stop through the turnaround route.

Therefore, the operator checks the state of the train as it moves from moment to moment on the screen S of the display device 2, and accordingly instructs the train to stop, run again, or run backwards from the operation panel 3. , can produce diamonds. As already explained, a train that is specified to travel in reverse will travel in the reverse direction of the trajectory it has traveled until then, and will erase that trajectory until a stop command is input or it returns to its starting point. I'm going to go. Therefore, this allows you to simply delete over-extended or incorrect diamond lines (this is called a streak) to a convenient location, making it easier to create diamonds. be able to.

Example 3. Station input r AVe teno t7i, repeat wo 9vj Kara 10:25
In this case, A station is JJ [return station, and it is also 2f from the 1st line.
Assuming that it is possible to return from urine, based on the above input, a person who took the return route of 1st line at that place will be able to return to line 1 for the specified time. You will have to alternate between the train and Platform 2 nine times.

This situation can be confirmed by being displayed on the display device 2 as shown in FIG.

Example 4. A train that arrives at 8:50 am at 8:50 am will start running after 7:00 am.'' In this case, starting from 8:50 am B station, the train's trajectory is traced back in time. Let it calculate and calculate the travel trajectory to reach that point.

Figure 5 shows this diagram displayed on the screen S of the display device 2, and the travel trajectory is traced back until it is calculated that the arrival time at the destination station of the next route is before the specified 7 o'clock. Made.

FIG. 6 is a flowchart illustrating the operation of the above embodiment, and specifically shows the case of one train input shown in Example 1 in detail.

By the way, in the above embodiments, the explanation was given regarding the operation schedule of railway vehicles, especially trains, but the misfire 8JJ is not limited to this, but can be applied to any transportation system that requires a schedule for operation management. That goes without saying.

In addition, as is clear from its function, the device 6- according to this A1 is used to create a timetable in a transportation system by 1 ton.
For example, it can be applied as a traveling simulator for a moving object. In other words, by making a moving body run from an arbitrary starting point, it is possible to simulate the running state of 8Nb bodies at each point, and by making the first number of moving bodies run at the same time, the competition β11 '1, etc. can be easily displayed and displayed.
As explained above, according to the present invention, it is possible to obtain excellent effects such as actually making it unnecessary to run a moving body for fat determination. You can simply create parallel diamonds with minimal input,
It is possible to provide an automatic timetable creation system that makes full use of the advantages of the interactive radar input system and can easily create and create an in-person travel timetable.
