The present invention relates to a diagram making device for making a diagram called an operation plan.

[0002]

2.

The above-described conventional timetable creating apparatus has a function of automatically checking time-related driving conditions such as a driving time interval and a crossing obstacle time interval when creating a timetable. .. However, other conditions cannot be mechanized yet, and are being input by human beings while checking. In particular, the amount of power used by the diamond is not checked at all because the power management department is different from the department that creates the diamond and there is no established method to predict the amount of power used based on the diamond. A diamond is made. For this reason, it is almost the case that the actual amount of electric power used is known only at the stage of creating a diamond and implementing it.

Even so, until now, there was no particular problem because the capacity of the substation and the contract with the electric power company had a sufficient margin, but in recent years, due to the sophistication of train density and improvement of vehicle output, etc. As a result of the timetable revision, problems such as shortage of capacity at substations and over-consumption of electric power with electric power companies have occurred.

Therefore, the present invention has a function of successively predicting the amount of electric power used in the substation with respect to the created timetable or the timetable being created, whereby the capacity of the substation and the contracted power with the electric power company are contracted. It is an object of the present invention to provide a diagram making device that can take proactive measures without causing problems such as overload.

The power condition that verifies the used power amount in the time range specified by the data such as the power curve and vehicle kilometer-power amount, and verifies whether the substation capacity or contract power is not exceeded. It is obtained by and a testimony section.

[0007]

According to the invention corresponding to claim 1, the schedule of the feeding section / time range of the substation for predicting the target schedule stored in the schedule storage unit is sequentially designated, and the designated schedule range is set. The calculation data stored in the power data storage unit is converted so that it can be used. Based on the calculation data, the amount of electric power used by the train in the timetable is calculated. Since it is determined that the boundary value of the electric energy stored in the storage unit is exceeded, it can be verified whether or not the capacity of the substation or the contracted electric energy with the electric power company is exceeded, and proactive measures can be taken.

In addition, the prediction range management unit 76 that stores the sum of the power consumption of the calculated value integration unit 74 of the specified feeding section / time range and the excess of the boundary value of the excess determination unit 75 is configured and created by the prediction range management unit 76. Find the amount of power used by the timetable for each feeding section and the time range required for verification,

In addition, the prediction range management unit 76 gives an instruction to start calculation of the next target feeding section / time range according to the order designated in advance.

In the present embodiment, the actual train travel is converted into a distance-time curve to obtain the boundary value of the target feeding section / time range, and the power consumption of each train is also predicted for each type. Since it is calculated based on the curve, the power consumption of the diamond can be predicted with high accuracy.

In addition, the electric energy boundary value storage unit 63 stores the electric energy boundary values of the target prediction time range / predicted feeding range, and compares the values with the predicted values of the used electric energy to judge the excess. Therefore, the amount of electric power used can be evaluated immediately after setting the timetable, and can be changed by the streak setting / changing unit 3 to eliminate the excess.

In this embodiment, since the electric power curve of the railway is generally expressed as a function of the distance, the electric energy used in the target range of each train is predicted by using the distance as a variable as shown in the equation (1).
When the electric power curve is obtained as a function of time, the boundary distance calculation unit 72 obtains the boundary value on the predicted time range / predicted feeding range in time from the distance-time curve of each train running, and the time is calculated by the following equation. It is possible to calculate in the same way with the variable.

[0026]

[Equation 3] Here, Tyj and Tzj are the start point and the end point of the boundary value on the time axis on the predicted time range / predicted feeding range of the j train.

Further, the present method requires a power curve and a distance-time curve for train travel. However, if these are not available, or if macro prediction is sufficient, the following simple method is used. The method is also effective. That is, with the configuration of FIG. 5, the vehicle km calculation unit 77 calculates the vehicle km (the number of vehicles × distance traveled) of each line in the stored predicted time range / predicted feeding range for the timetable stored in the timetable storage unit 4, Furthermore, the sum is calculated. In addition, the relationship between the vehicle kilometer and the used electric energy is stored in the vehicle kilometer / electric power correspondence storage unit 64, and in the used electric energy calculation unit 73 ′, the total vehicle kilometer calculated by the vehicle kilometer calculation unit 77 is used. By referring to the relationship between the vehicle kilometer and the power consumption stored in the power correspondence storage unit 64, the power consumption of the target range is calculated.
