(1) First Embodiment (1-1) Configuration of Train Operation Management System As shown in FIG. 1, a train operation management system 10 according to this embodiment includes a train control device 101, a drive state determination device 102, and The drawing apparatus 103 is configured.

  The train control device 101 includes information processing resources such as a CPU and a memory. The CPU functions as an arithmetic processing device and controls the operation of the train control device 101 in accordance with a program, arithmetic parameters, etc. stored in the memory. The train control device 101 includes an information input device such as a keyboard, a switch, a pointing device, and a microphone, and an information output device such as a monitor display and a speaker.

  The train control device 101 outputs the traveling train position 105 based on the input time 104. The train control device 101 provides the train position 105 to the driving state determination device 102 and the drawing device 103.

  Since the driving state determination apparatus 102 and the drawing apparatus 103 also have the same hardware configuration as the train control apparatus 101, detailed description thereof is omitted.

  The driving state determination device 102 determines the driving state of each train based on the train position 105 provided to the driving state determination device 102, and outputs a driving state 106 indicating whether the train is powering or regenerating. The driving state determination device 102 provides the driving state 106 to the drawing device 103.

  Based on the train position 105 provided from the train control device 101 and the drive state 106 provided to the drive state determination device 102, the drawing device 103 displays a train trajectory and a train on a graph with time and position as axes. Draw the driving state of the train.

  In the present embodiment, the train operation management system 10 includes the train control device 101, the drive state determination device 102, and the drawing device 103. However, in one device having the hardware configuration described above, It is good also as a structure provided with the program which performs the function of the train control apparatus 101, the drive state determination apparatus 102, and the drawing apparatus 103. FIG.

(1-2) Configuration of Each Device Next, the configuration of the train control device 101 will be described with reference to FIG. As shown in FIG. 2, the train control device 101 includes a train position estimation device 201 and a diagram information 202.

  The train position estimation apparatus 201 outputs the train position 105 of the running train with respect to the input time 104. The diagram information 203 defines the correspondence between time and position for each train. For example, the time when the train stops at each station and the time when the train departs are defined.

  The train position estimation apparatus 201 outputs the train position 105 of the running train corresponding to the time 104 for the input time 104 and provides the train position 105 to the drive state determination apparatus 102.

  Next, the configuration of the drive state determination device 102 will be described with reference to FIG. As shown in FIG. 3, the drive state determination device 102 includes a drive state prediction device 301, a regeneration expiration prediction device 302, and a travel pattern 303.

  The driving state prediction device 301 refers to the train position 105 provided from the driving state determination device 102, and predicts a driving state in which regenerative power can be realized in an ideal environment with respect to the traveling pattern 303 of each train. The driving state 304 is output.

  As shown in FIG. 4, the travel pattern 303 holds information on the speed and notch with respect to the position. Notch refers to the stage of acceleration of the train. As the train drive state, three states of power running, regeneration, and stop are defined. When the notch is positive, it indicates power running, when the notch is negative, regeneration is indicated, and when the notch is 0 or stopped, it indicates a stopped state.

  The driving state prediction device 301 outputs a predicted driving state 304 indicating whether the driving state of the train at the train position 105 is power running, regeneration, or stop from the input train position 105 and the notch corresponding to the train position 105. . The drive state prediction device 301 provides the predicted drive state 304 to the regeneration expiration prediction device 302.

  The regeneration / expiration prediction device 302 determines whether excessive regenerative power is generated when the predicted drive state 304 output from the drive state prediction device 301 is regeneration. When it is predicted that excessive regenerative power will be generated, the regeneration expiration prediction device 302 stops the driving state of the train and outputs the driving state 106. The regeneration expiration prediction device 302 provides the output driving state 106 to the drawing device 103.

  With reference to FIG. 5, the specific operation of the regeneration expiration prediction device 302 will be described. As shown in FIG. 5, the regeneration expiration prediction apparatus 302 first determines whether or not the predicted drive state 304 for a certain train is regenerative (S101).

  In step S101, when it is determined that the predicted drive state 303 is regenerative, the processing after step S102 is executed to determine whether excessive regenerative power is generated. On the other hand, if it is determined in step S101 that the predicted drive state 303 is not regenerative, the input predicted drive state 303 is output as the drive state 106 (S106).

  In step S101, when the predicted drive state 303 is regeneration, the possibility of regeneration is determined according to the state of another train. Specifically, the regeneration expiration prediction device 302 counts the number of power train vehicles Np in the range of the reference distance x0 from the own train position (S102). Further, the regeneration expiration prediction device 302 counts the number Nr of regenerative trains in the range of the reference distance x0 from the own train position (S103). The reference distance x0 is set in advance from information such as the overhead wire resistance of the route, using the power reach as a guide.

  Then, the regeneration expiration prediction device 302 determines whether the number of power trains Np counted in step S102 is smaller than the number Nr of regenerative trains counted in step S103 (S104).

  If it is determined in step S104 that the number of power trains Np is smaller than the number of regenerative trains Nr, the regenerative power becomes surplus, and the expected utilization of the regenerative power of this train is low. S105).

  On the other hand, if it is determined in step S104 that the number of power trains Np is greater than the number of regenerative trains Nr, the predicted driving state 303 is output as the driving state 106 as it is because the use of the regenerative power of this train is high. S106).

The drawing pattern determination apparatus 601 has a drawing pattern table 6010 shown in FIG. 7, and selects a drawing line type 504 corresponding to the driving state 106 with reference to the table.

  The drawing pattern table 6010 stores line type information for drawing a train driving state on a two-dimensional graph. The drawing pattern table 6010 includes, for example, a drive state column 6011, a color column 6012, a thickness column 6013, and a line type 6014 as shown in FIG. The driving state column 6011 stores information indicating the driving state of the train, and examples of the driving state include power running, regeneration, and stop. The color column 6012, the thickness column 6013, and the line type 6014 store information on the color, thickness, and line type of the line type that is drawn corresponding to the driving state.

A drawing line type 504 is selected. When the driving state 106 is regenerative, reference is made to an entry in which regenerative is stored in the driving state column 6011 of the drawing pattern table 6010, the color is black, the thickness is 2pt, and the line type is a line. Select 504. When the driving state 106 is stopped, an entry whose driving state 6011 in the drawing pattern table 6010 is stopped is referred to, and a drawing line type 504 whose color is black, thickness 1 pt, and line type is a dotted line is selected. . The drawing pattern determination apparatus 601 provides the drawing information creation apparatus 602 with drawing line type information 604 of the selected drawing line type 504.

  The drawing information creation device 602 is necessary for creating a two-dimensional graph from the input time 104, the train position 105 provided from the train control device 101, and the line type information 604 provided from the drawing pattern determination device 601. The data array is output to the drawing screen 603 as drawing information 605.

  The drawing information 605 stores information for creating a two-dimensional graph in which the x-axis is the time and the y-axis is the position and the train driving state is indicated by different line types. The drawing information 605 includes an x coordinate field 6051, a y coordinate field 6052, a color field 6053, a thickness field 6054, and a line type field 6055, as shown in FIG. Information on the time 104 is stored in the x coordinate column 6051, and information on the train position 105 is stored in the y coordinate column 6052. The color column 6053, the thickness column 6054, and the line type column 6055 store line type color, thickness, and line type information for drawing the driving state of the train.

  In FIG. 8, for a train, the color of the line type drawn at time 1 and position 1 of the two-dimensional graph is gray, the thickness is 2 pt, the line type is line, and the color of line type drawn at time 2 and position 2 Is black, the thickness is 1 pt, the line type is a dotted line, the color of the line type drawn at time 3 and position 3 is black, the thickness is 2 pt, and the line type is a line.

The trajectory and driving state of the train are visualized by the two-dimensional graph drawn on the drawing screen 603.

  FIG. 9 shows an example of the drawing information 605 drawn on the drawing screen 603. As shown in FIG. 9, in the drawing information 605, the trajectory of each train is displayed on a two-dimensional graph with time on the horizontal axis and position on the vertical axis, and each trajectory is a line that varies depending on the driving state of the train. Displayed by seed.

  For example, in FIG. 9, for the train A, the operation locus from the station D to the station A is displayed, and the driving state between the station D and the station C is power running, stop, and the driving state between the station C and the station B. It is understood that the driving state between the power running, stop, regeneration and the station B and the station A is power running, stop, regeneration. For train B, the operation trajectory from station A to station D is displayed, the driving state between station A and station B is power running, stop, regeneration, and the driving state between station B and station C is power running. It can be seen that the driving state between the station C and the station D is power running, stop, and regeneration. For the train C and the train D, the operation trajectory and the driving state are displayed on the two-dimensional graph.

  As described above, since the operation trajectory of each train is displayed with different line types according to the driving state on the two-dimensional graph of FIG. 9, it is possible to easily grasp the usage status of the regenerative power.

(1-3) Effects of this embodiment As described above, according to this embodiment, the use of regenerative power of each train is visualized on a diagram that displays the trajectory of the train, and the regenerative power is enabled. This makes it easy to create an operation plan that can be used for various purposes.

(2) Second Embodiment In the present embodiment, a train trajectory is drawn on a two-dimensional graph, as in the first embodiment. The configuration is different from that of the first embodiment in that the color tone of the seed is changed. Hereinafter, detailed description of the same configuration as that of the first embodiment will be omitted, and a configuration different from that of the first embodiment will be described in detail.

(2-1) Configuration of Train Operation Management System As shown in FIG. 10, the train operation management system 11 according to the present embodiment includes a train control device 101, a power calculation device 1001, and a drawing device 1003.

  Since the hardware configurations of the train control device 101, the power calculation device 1001, and the drawing device 1003 are the same as those of the train control device 101 of the first embodiment, detailed description thereof is omitted. Moreover, since the train control apparatus 101 is the same as that of 1st Embodiment, detailed description is abbreviate | omitted.

  The power calculation device 100 calculates the power consumption of the running train based on the train position 105 output from the train control device 101. The power calculation device 100 provides the calculated train power consumption 1002 to the drawing device 1003.

  The drawing device 1003 is based on the train position 105 provided from the train control device 101 and the train power consumption 1002 provided from the power calculation device 100, and the train operation trajectory and Draw the power consumption of the train.

(2-2) Configuration of Each Device Next, the configuration of the power calculation device 1001 will be described with reference to FIG. As illustrated in FIG. 11, the power calculation device 1001 includes a drive state calculation device 1101, a required power calculation device 1102, a power correction device 1103, a travel pattern 303, and a drive characteristic 1106.

  The driving state calculation device 1101 calculates a notch 1105 and a speed 1106 corresponding to the train position 105 of each train based on the traveling pattern information 1104 that defines the speed and the notch with respect to the train position.

  The required power calculation device 1102 calculates the required power 1110 of each train based on the train output characteristic 1109 corresponding to the speed and the notch. As shown in FIG. 12, the train output characteristic 1109 holds a tensile force corresponding to the speed for each notch. Therefore, the required power calculation device 1102 determines the tensile force according to the notch and the speed with reference to the train output characteristic 1101, and outputs the product of the tensile force and the speed as the required power 1110.

  The power correction apparatus 1103 determines whether or not the regenerative power can be used in consideration of the required power of other trains, and calculates the actually usable regenerative power for the requested regenerative power.

  A specific operation of the power correction apparatus 1103 will be described with reference to FIG. As shown in FIG. 13, the power correction apparatus 1103 determines whether the required power of other trains is positive or negative (S201).

  If it is determined in step S201 that the required power of the train is positive, the required power is directly output as power consumption 1002 because the train is in a power running state.

  On the other hand, if it is determined in step S201 that the train power is negative, the vehicle is in a regenerative state, and the requested power may not be output depending on the situation of other trains. The process after S202 is executed.

  The power correction apparatus 1103 calculates the total power (total required power W) of the train in the range of the reference distance x0 from the target train (own train) position (S202).

  Then, the power correction apparatus 1103 determines whether the total required power W calculated in step S202 is positive or negative (S203).

  If it is determined in step S203 that the total required power W is positive, all of the regenerative power can be used, and the required power is output as it is as the power consumption 1002 (S205).

  On the other hand, if it is determined in step S203 that the total required power W is negative, the power of the own train calculated so that the total required power W becomes 0 is output as power consumption (S204). The case where the total required power W is negative is a state where the regenerative power is larger than the power running power, and thus the regenerative power is surplus. In this case, it is necessary to narrow the regenerative power so that the power running power and the regenerative power are balanced. For this reason, the power of the own train is calculated backward so that the total required power W becomes 0, and the calculated power of the own train is output as the power consumption 1002.

  Next, the configuration of the drawing apparatus 1003 will be described with reference to FIG. As shown in FIG. 14, the drawing apparatus 1003 includes a drawing pattern determination apparatus 1401, a drawing information creation apparatus 602, and a drawing screen 603.

Holds the drawn pattern. The drawing pattern determination apparatus 1401 determines the color and thickness of the line type corresponding to the input power consumption 1002 with reference to the drawing pattern shown in FIG.
