DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. Although the train operation simulation device of the present invention is actually realized by a high-performance computer having a large-capacity storage device and a display device, a functional configuration is shown in FIG. , A train operation fixed condition data file 2 for storing fixed condition data among various data used when the train operation simulation unit 1 executes the simulation calculation, and a simulation calculation result. And a simulation result file 3 to be executed.
A simulation condition file 4 for storing simulation condition variable data, and a human interface (HMI) unit 5 for interactively updating and registering simulation condition data during the simulation calculation and for displaying simulation results are provided. . Further, a shared memory 6 for storing simulation results and simulation conditions is provided.

In this train operation simulation device,
The train operation simulation unit 1 performs a train operation simulation based on the fixed condition data file 2 and the simulation conditions registered in the simulation condition file 4 input from the HMI unit 5. The calculation results of the train operation simulation are stored in the simulation result file 3 and displayed by the HMI unit 5.

The simulation conditions can be changed or added at any time by the HMI unit 5 and are stored in the simulation condition file 4 and read by the train operation simulation unit 1 at regular intervals and used for simulation. In addition, the train operation simulation unit 1 saves the simulation result in the simulation result file 3 at a fixed cycle, and displays the simulation result on the HMI unit 5.

The simulation conditions that can be registered in the simulation condition file 4 and the shared memory 6 include (1) simulation double speed n value (2) temporary stop command (3) temporary speed limit command and its speed limit (4) station stop command Station stop release command (5) Plan schedule change command and changed plan schedule (6) Simulation speed change command and simulation speed.

The train operation simulation by the simulation unit 1 is executed according to a large-scale simulation program. If the functions are divided into related functions and described, the configuration shown in FIG. Note that, unlike the conventional example, in the present invention, the diamond data 1009, the interlocking condition data 1010, the temporary speed limit setting data 1011 and the trouble setting data 101
2. Each of the vehicle characteristic data 1013 and the route data 1014 may be updated or added by the setting or change input of the simulation conditions from the HMI unit 5, and may be changed from the initial data.

Hereinafter, a train operation simulation apparatus according to a first embodiment of the present invention will be described with reference to FIGS. The train operation simulation device according to the first embodiment is characterized in that the train operation simulation unit 1 executes the simulation shown in the flowchart of FIG.

First, the time tc1 of the clock of the computer before starting the subsequent series of processing is measured (step 10).
1) Then, train speed and position calculation processing is performed (step 102).

Here, the traction force characteristics of the train and the vehicle weight are registered in the vehicle characteristic data 1013, and the traction force Fa of the train is given as a function of the train speed v.

Fa = f1 (v) (1) Then, the train has a lower one of the maximum speed of the route indexed from the route condition data 1004 and the speed limit by the signal indication from the signal system function unit 1004. Can be accelerated to one speed. Further, the running resistance based on the slope or curve of the route is indexed from the route condition data 1014. Although there is a running resistance depending on the running speed, here, these running resistances are collectively referred to as Fb. The running resistance Fb changes depending on the vehicle type, speed, weight, and route position of the train.

Assuming that the vehicle weight is M, during acceleration to the target speed, the train position X (t1), X (t1 + dt), the speed V (t1), V
As (t1 + dt), the speed and the position after the dt time can be approximately expressed as in the following equations (2) and (3).

[0026]

V (t1 + dt) = (Fa−Fb) · dt / M + V (t1) = (f1 (V (t1)) − Fb) · dt / M + V (t1) (2) X (t1 + dt) = X (T1) + V (t1) · dt (3) Therefore, dt is obtained by the equations (1) to (3).
The train position and speed for each time can be obtained. When decelerating, the calculation is performed on the assumption that the vehicle decelerates at a constant acceleration (negative). Note that the calculation of the position and speed in step 102 is performed for all train groups to be simulated.

When the train speed and position calculation processing is completed, the time t1 on the schedule is advanced to t1 + dt.

Thereafter, if the time t1 on the diagram is the time to end the simulation, the simulation is ended. Otherwise, the computer time after the next processing is measured (step 104). The post-processing computer time measurement refers to measuring the time of the computer after executing the processing of steps 102 and 103. The computer time obtained here is defined as tc2.

In the next step 105, the processing of the computer is suspended. Here, assuming that the processing stop time ts is ts = dt− (tc2−tc1) (4), the calculation of the position and the speed during the dt time on the diagram from the time of step 101 can be performed on the computer using the dt processing time. This means that the calculation was performed at the same time as the actual train operation.

The temporary stop processing in step 105 can be realized by, for example, a description of call sleep (ts) using a sleep function in the FORTRAN language.

Here, when simulating the time on the diagram at n times the time on the computer, the processing may be temporarily stopped by ts = dt / n- (tc2-tc1) (5). For this n, t
The value when s = 0 is the maximum value that can be taken, and nmax = dt / (tc2-tc1) (6). Therefore, this is the highest simulation speed in terms of the performance of the computer that is executing the simulation.

As described above, according to the first embodiment, the train operation simulation status can be grasped in accordance with the actual train operation speed, and the train operation simulation can be performed n times more than the actual train operation. It becomes possible to grasp by turning twice faster.

That is, similarly to the first embodiment, after measuring the pre-processing computer time tc1 in step 101, a temporary stop command reading process is performed (step 201). This temporary command stop command is input by the operator from the HMI unit 5 in FIG. 1 and is registered in the simulation condition file 4 and the shared memory 6. For this purpose, a temporary stop command is written as a flag (step 202), and the simulation unit 1 accesses the simulation condition file 4 and reads the temporary stop command flag in step 201 of the simulation.

If the temporary stop command flag has been set in the temporary stop command reading process in step 201, the process waits until the temporary stop command flag disappears (step 20).
3).

If the temporary stop command flag is not set,
Alternatively, if the temporary stop command setting flag has disappeared, the processing shifts to the processing after step 102, and the train speed and position calculation processing is executed in the same manner as in the first embodiment (step 10).
