Description

  The present invention relates to a train diagram creation support device for a railway system.

  In recent years, in the railway technology field, energy saving has been attempted from the viewpoint of global environment and cost reduction. One of them is the utilization of regenerative power in railway vehicles. Regenerative power is generated when the motor operates as a generator and decelerates, and the generated power is returned to the overhead line.

  In this way, regenerative power is one of the useful means for energy saving, but the regenerative power is returned to the overhead line when there is a train that consumes power by powering etc. in the same power section It is. When the train does not exist, the regenerative power cannot be returned to the overhead line to prevent the overhead line voltage from increasing extremely, and a reduction in braking ability called regeneration invalidation occurs. As a countermeasure against this regenerative invalidation, there is also a vehicle equipped with an air brake, a power generation brake, etc., and when regenerative invalidation is about to occur, the brake means is switched to an air brake or a power generation brake to release kinetic energy as thermal energy. . However, in this countermeasure train, energy that can be used originally is discarded, so that energy use efficiency is lowered.

  In order to improve the energy use efficiency, when the overhead voltage that may cause regenerative expiration is about to rise, the generated power is collected and stored in the flywheel / storage battery in the substation. Technology for charging and technology for providing a power storage device in the vehicle itself have been developed. However, there is a problem that it is expensive to introduce these facilities.

  Therefore, as another method to improve the energy utilization efficiency, there is a method of reducing the regenerative invalidation rate by building a diamond that enables effective use of regenerative power at the time of train scheduling. Yes.

  Patent Document 1 relates to a diamond creation support device, and when a diamond change of a plurality of patterns is performed on an already assembled diamond, a graph or a difference in a regeneration rate when the diamond change of each pattern is performed It is displayed as a table to encourage selection of diamonds with a high regeneration rate. However, there is a problem that it is difficult to quickly grasp the difference in the regeneration rate, such as where the regeneration rate is low, in the graph or numerical display.

Embodiments of a diamond creation support apparatus according to the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a diagram creation support apparatus according to an embodiment of a diagram creation support apparatus according to the present invention.

  In FIG. 1, the diagram creation support apparatus includes a data storage unit 1, an input unit 2, an arithmetic processing unit 3, and an output unit 4. The data storage unit 1 includes basic data 11 and diamond data 12. When a data request is received from the arithmetic processing unit 3, the data storage unit 1 sends the corresponding data to the arithmetic processing unit 3. In addition, when the data storage unit 1 receives a data change request from the arithmetic processing unit 3, the data storage unit 1 changes the corresponding data. The basic data 11 is terrain data such as the slope where the track is laid, data indicating the characteristics of the vehicle such as operation curves (between each station and for each knitting), knitting growth and weight, and position data of the feeding section, The diamond data 12 is a schedule necessary for operating a train and organization data of a train traveling on the diamond.

  The input unit 2 is an input device such as a mouse or a keyboard. Input information from the input unit 2 is passed to the arithmetic processing unit 3.

  The calculation processing unit 3 includes a power running power calculation unit 31, a regenerative power calculation unit 32, a regenerative power usage rate calculation unit 33, and a drawing processing unit 34. Further, when a change input of the basic data 11 or the diagram data 12 stored in the data storage unit 1 is received from the input unit 2, a change request is made to the data storage unit 1.

  The power running power calculation unit 31 is necessary for accelerating the train between the stations for each train formation based on the terrain data that is the basic data 11 stored in the data storage unit 1 and the data indicating the characteristics of the vehicle. Calculate the power running energy per unit time. At that time, it is determined where the power running power is required in the power transmission section from the position of the train.

The regenerative electric power calculation unit 32 uses the regenerative brake between the stations for each train formation based on the topographic data that is the basic data 11 stored in the data storage unit 1 and the data indicating the characteristics of the vehicle. Calculate the amount of regenerative power per unit time that is generated. At this time, the regenerative power anywhere in feeding circuit section from the position of the train is Luca determined to occur.

  The regenerative power usage rate calculation unit 33 first extracts the knitting information and each train diagram from the diagram data 12 stored in the data storage unit 1, and divides the train diagram for each station. Based on the scheduling information, refer to the power running power amount, regenerative power amount per unit time of each divided train schedule, and the feeding section where each power is required or generated, and per unit time of the feeding section Is added to the total power running energy required for the power supply and the total regenerative power generated per unit time in the feeding section. After processing all diamonds, the regenerative power usage rate (= total power running power amount / total regenerative power) that indicates the percentage of regenerative power used from the total power running power per unit time and total regenerative power generated in each feeding section Amount). However, when the total power running power amount> the total regenerative power amount, the regenerative power usage rate may be 100% (that is, the usage rate is 100% when the total regenerative power amount is used).

  The drawing processing unit 34 calculates the regenerative power usage rate based on the regenerative power usage rate calculated by the regenerative power usage rate calculating unit 33 and the threshold value stored in the data storage unit 1 or input from the input unit 2. Threshold processing is performed on the data, and data indicating “unit time-feeding section area” in which the regenerative power usage rate is less than or less than the threshold is created. This data is passed to the output unit 4.

  The output unit 4 can be a display output device such as a display, a CRT, or a projector, a sound source output device such as a speaker, or both a display and a sound source output device. The data is output based on the data created by the drawing processing unit 34 of the arithmetic processing unit 3.

  In the above description, when calculating the regenerative power usage rate, the regenerative power usage rate was calculated for all “unit time-feeding section areas”, but when the regenerative power amount is small, the power running power amount slightly fluctuates. The regenerative power usage rate fluctuates greatly. For this reason, when the total regenerative power amount is equal to or less than the threshold value, the regenerative power usage rate in the “unit time-feeding section area” may not be calculated.

Next, processing of the diagram creation support apparatus of the present invention will be described with reference to the flowchart of FIG.
When it is executed from the input unit 2, the operation starts. From the basic data 11 of the data storage unit 1, the data indicating the characteristics of the vehicle related to one train among the data of all trains, the terrain data such as the gradient, and the driving The curve is taken out, and the powering power amount and the regenerative power amount per unit time are calculated by the powering power calculation unit 31 and the regenerative power calculation unit 32 for each station (101). This process is repeated for all the formations (102, 103, 101).

Next, in the regenerative power usage rate calculation unit 33, the train data and diagram data of one train are extracted from the diagram data 12 of the data storage unit 1 (104), and the diagram is divided for each station. In order from the starting station, based on information between stations which is divided knitting data, calculates the regenerative electric energy and running power amount of every single much time and running power computing unit 31 with regenerative power calculation unit 32 (105). Further, since the standing line position can be estimated from the operation curve and the time, the feeding section of the standing line position is determined based on the position data of the feeding section (105). The calculated power running power amount and regenerative power amount are respectively added to the total power running power amount and the total regenerative power amount per unit time of the feeding section (106). This process is repeated for each diamond while proceeding to the destination station every unit time (107, 108, 105, 106).

  The processes in steps 104 to 108 are processes for one train schedule, and this process is performed for all train schedules to calculate the total power running power and the total regenerative power per unit time generated in each feeding section. (109, 110, 104 to 108). The regenerative power usage rate calculation unit 33 calculates the regenerative power usage rate (= total power running) from the total power running power per unit time generated in each feeding section and the total regenerative power calculated in the above processing. The electric energy / total regenerative electric energy is calculated (111).

  Subsequently, based on the regenerative power usage rate calculated by the regenerative power usage rate calculating unit 33 and the threshold value stored in the data storage unit 1 or input from the input unit 2 in the drawing processing unit 34, the regenerative power is concerned. Threshold processing is performed on the usage rate, and data indicating “unit time-feeding section area” that is less than or less than the threshold is created for the operator (112).

  Finally, on the basis of the data created by the drawing processing unit 34, the output unit 4 emits an output by display, sound, or the like.

Below, the Example in the output part 4 is described.
FIG. 3 is a display example (display example 1) in the case where the output unit 4 is a display output device such as a display (hereinafter, the output unit 4 is referred to as a display), and is a plane having time and position as axes. Is displayed on the display. The time axis direction that is the horizontal axis is divided every unit time, and the position axis direction that is the vertical axis is divided for each feeding section, and the area surrounded by these is calculated by the regenerative power usage rate calculation unit 33. It corresponds to the unit time-feeding section area. By making the area where the regenerative power usage rate is below or below the threshold among the areas on this display stand out, that is, by making a pattern or color, etc. Can easily determine a “unit time-feeding section area” where the regenerative power cannot be used effectively.

In the above description, the threshold value for determining the regenerative power usage rate is one. However, a plurality of threshold values may be provided, and a pattern or color according to each threshold value may be provided. Moreover, although the display method was a plane, as shown in FIG. 4, you may display by the method of expanding three-dimensionally according to the grade of the grade below or less than a threshold value.

FIG. 5 is a display example (display example 2) when the output unit 4 is a display output device such as a display (hereinafter, the output unit 4 is referred to as a display). In addition to the display example 1, regenerative power is shown. Information on the time zone and feeding section of the section where the usage rate is less than or less than the threshold is displayed as character information. By displaying as character information, a specific time, position, name, etc. can be shown. In Display Example 1, the regenerative power usage rate is displayed with a pattern or color depending on the threshold, but it is impossible to display all information at once due to restrictions such as the size of the display. In some cases. In this case, by combining with character information, an area outside the display range can be displayed as character information, and the operator can be notified that there is a portion outside the display range. In Display Example 2, text information is added to the output unit 4, but a sound source output device such as a speaker is attached to the output unit 4, and information corresponding to the threshold value for the regenerative power usage rate is noted with voice or the like. May be alerted .
