  The present invention relates to an energy saving diagram proposing device, and more particularly to an energy saving diagram proposing device that proposes a train schedule that can be operated with more energy saving.

  In the railway system, the train schedule that is operated daily is fixed for a certain period. However, if there is some kind of driving trouble, such as equipment failure or accident, even within that fixed period, the operation schedule needs to be changed. In recent years, in response to the issuance of a power usage restriction order and a power saving request from an electric power company, a railway operator needs to appropriately create a special diagram in which the number of train operations is reduced in order to reduce power consumption as appropriate. Under the circumstances as described above, various techniques for appropriately and easily changing the service schedule have been proposed.

  For example, Patent Document 1 proposes a technology that realizes a reduction in an excess amount of power consumption by changing a diagram that takes into account the amount of power used in order to recover the diagram early when the diagram is disturbed. .

<Embodiment 1>
<Configuration>
FIG. 1 is a functional block diagram of an energy saving diagram proposing device 100 according to the first embodiment. In FIG. 1, the same reference numerals are the same or equivalent, and this is common throughout the entire text of this specification. Furthermore, the forms of the components appearing in the entire text of this specification are merely examples, and are not limited to these descriptions.

  In FIG. 1, the energy saving diagram suggesting apparatus 100 includes a convenience calculation unit 2, a power consumption calculation unit 3, a data acquisition unit 4, and a diagram creation unit 5. The storage unit 10 outside the energy saving diagram suggestion apparatus 100 stores in advance data of entrance and exit histories at train stations and passenger stations (hereinafter simply referred to as entrance / exit history). The data acquisition unit 4 acquires train schedule and entry / exit history data from the external storage unit 10. In addition, the memory | storage part 10 may be incorporated in the energy saving diamond proposal apparatus 100, and the memory | storage part 10 becomes the data acquisition part 4 in this case.

  The operator designates the train for which energy is to be reduced and the energy saving operation type to be applied (hereinafter simply referred to as the operation type) via the input unit 20. The operation type will be described later.

  The diamond creation unit 5 creates a second diamond by applying a predetermined operation type to a predetermined diamond (that is, the first diamond). Here, the predetermined diamond is a diamond designated by the operator via the input unit 20. Further, the predetermined operation type is an operation type designated by the operator via the input unit 20. The created second diagram is output to the external display 30, for example. In FIG. 1, the data is output to the display 30, but the present invention is not limited to this, and any device or storage device capable of displaying information may be used.

  The convenience calculator 2 calculates the number of passengers on the train based on the entry / exit history and the second diagram. The convenience calculator 2 further calculates the amount of decrease in convenience. In Embodiment 1, the amount of decrease in convenience is calculated as the number of passengers whose time of arrival at the station changes because the first diagram is changed to the second diagram.

  The convenience calculator 2 outputs the calculation result to the outside. Here, outputting to the outside means, for example, visually outputting to the display 30 connected to the energy saving diagram suggesting apparatus 100. Further, the convenience calculator 2 outputs the number of passengers on the train calculated based on the entry / exit history and the second diagram to the power consumption calculator 3.

  The power consumption calculation unit 3 calculates the power consumption for train travel based on the number of passengers input from the convenience calculation unit and the second diagram input from the diagram creation unit. The power consumption is visually output, for example, on the display 30 connected to the energy saving diagram proposing device 100.

  The operator evaluates the second diagram visually output to the display 30 connected to the energy saving diagram suggesting apparatus 100, the amount of decrease in convenience, and the amount of power consumption. Then, the operator determines whether or not the first diagram is to be rearranged to the second diagram.

  In addition, in this Embodiment, as shown in FIG. 2, the diagram includes a diagram ID for identifying a diagram, a train code for identifying each train, and a departure and arrival time of each train at each station. . Here, “−” shown in FIG. 2 means that the train attached with the train passes through the station attached with the train without stopping. Note that the diagram is not limited to the information shown in FIG. 2, and may include information such as the passing time of a passing station, a returnable station, and a evacuable station, for example.

  The operation types are thinning operation, train shortening operation, parallel movement operation (early departure), parallel movement operation (late departure), and streak laying operation in which train operation is performed at a lower traveling speed. Moreover, if the specific application example of each operation type is a train shortening operation, the number of trained vehicles is shortened to a certain threshold, for example, 60% (10 trains are 6 trains). For parallel movement operation (early departure), for example, each station is left early for 5 seconds. For parallel movement operation (delayed), for example, each station is delayed for 5 seconds. For streak driving, for example, the arrival time is delayed by 5 seconds without changing the departure time of each station. In addition, the specific application example of each driving | running | working type shown here is one example, Comprising: It is not limited to these.

  In the first embodiment, the convenience is the number of passengers who are affected by changing the first diagram to the second diagram. The convenience of decimation is defined as the number of passengers who were supposed to get on the decimation train. The convenience of train shortening operation is defined as the number of passengers who should have boarded a train with shortened train. The convenience of parallel movement driving (early departure) is defined as the number of passengers who can no longer board due to early departure. The convenience of parallel driving (delayed) is defined as the number of passengers who arrive late due to delayed departure. The convenience of laying down streaks is defined as the number of passengers who arrive late due to laying down streaks. Note that the number of passengers affected by the driving type shown here is merely an example, and is not limited to these descriptions.

  In the entrance / exit history, for example, passenger information shown in FIG. 3 relating to entrance and exit of a passenger's station is stored. This entry / exit history is input in advance by a passenger, for example. Alternatively, the entry / exit history is generated based on past information stored in the database.

  In the input unit 20, for example, the operator designates one train diagram by clicking the mouse from the current diagram displayed on the display. Further, the operation type to be applied to the selected train diagram is selected from the display of the operation type displayed on the display by clicking the mouse. In this way, the train and the type of operation for which the diamond is to be saved are determined.

  The convenience calculator 2 creates passenger flow information related to the passenger flow (passenger flow) by train transportation based on the second diagram and the entry / exit history. Here, it is assumed that the passenger gets on the starting train of the boarding station, for example. Passenger flow information indicates the correspondence between passengers and boarding trains, and the number of passengers on the train is calculated based on the passenger flow information.

  The power consumption calculation unit 3 is based on the number of passengers, the second diagram, and the vehicle information stored in the power consumption calculation unit 3, for example, as shown in FIG. Calculate the amount of power consumption per specified time). Here, in the first embodiment, as shown in FIG. 4, the vehicle information includes a train code that identifies each train, and the number of trains that form each train (the number of trains) and the type (vehicle type). It is out.

  Note that the vehicle information is not limited to the information illustrated in FIG. 4, and may include information such as a vehicle that can be used on the day of operation (spare vehicle) and whether or not the trains can be divided. The power consumption obtained by the calculation of the power consumption calculation unit 3 may be “narrow power consumption” corresponding to the power consumption itself, or the power consumption may be a positive value and the regenerative power. May be a “broad power consumption amount” obtained by taking the sum of these values as negative values. In the following description, the power consumption calculation unit 3 calculates the power consumption in a broad sense (the power consumption in a narrow sense for each unit time of each train and the regenerative power amount for each short time of each train), The power consumption in a broad sense may be referred to simply as “power consumption” for short.

<Operation>
Next, the operation of the energy saving diagram proposing device 100 in the present embodiment will be described. FIG. 5 is a flowchart showing the operation of the energy saving diagram proposing device 100.

  The data acquisition unit 4 of the energy saving diagram suggestion apparatus 100 first acquires the current diagram and the entry / exit history from the external storage unit 10 in step S101. Next, in step S102, the operator selects a train whose energy is to be reduced from the current diagram via the input unit 20. Further, the operation type to be applied to the diamond is designated. The designated train diagram (that is, the first diagram) and the operation type are input to the diagram creation unit 5.

  In step S103, the diagram creation unit 5 creates the second diagram by applying the designated operation type to the first diagram. Next, in step S104, the convenience calculator 2 creates passenger flow information based on the input second diagram and entry / exit history. Hereinafter, an example of the operation of the convenience calculation unit 2 in step S104 will be described in detail with reference to FIG.

  First, in step S1041 of FIG. 6, the convenience calculation unit 2 generates a travel route based on the second diagram for the passengers described in the entry / exit history. Here, the convenience calculation unit 2 combines, for each passenger described in the entry / exit history, a train that satisfies the condition that the passenger enters and exits the entrance station after the entrance time of the passenger and goes to the entry station. Generate a travel path.

  Next, in step S1042 of FIG. 6, the passenger flow information shown in FIG. 7 is created in which the movement routes are summarized for each passenger described in the entry / exit history. And the convenience calculation part 2 calculates the passenger number of each train based on passenger flow information.

  In step S105 in FIG. 5, the power consumption calculation unit 3 calculates the second diagram created in step S103, the vehicle information (FIG. 4) held by the power consumption calculation unit 3, and the calculation in step S104. Power consumption information is created based on the number of passengers. Hereinafter, an example of the operation of the power consumption calculation unit 3 in step S105 will be described in detail with reference to FIG.

  In step S1051 in FIG. 8, the power consumption calculation unit 3 corrects the vehicle weight of each train based on the number of passengers calculated in step S104. For example, the power consumption calculation unit 3 performs correction to add a weight obtained by multiplying the number of passengers by an average body weight (for example, 65 kg) to the vehicle weight.

  Next, in step S1052 of FIG. 8, the power consumption calculation unit 3 calculates the power consumption of each train based on the train weight corrected in step S1051 and the second diagram. For example, the power consumption calculation unit 3 acquires the acceleration (deceleration) and the distance at which the acceleration (deceleration) is performed for the train with the corrected vehicle weight from the second diagram, and the corrected vehicle weight and By multiplying the acceleration (deceleration) and the distance, the power consumption and the regenerative power in a narrow sense are calculated. The power consumption calculation unit 3 performs the operations of steps S1051 and S1052 as described above for each train, thereby including the power consumption (the power consumption and the regenerative power in a narrow sense) shown in FIG. Ask for information.

  Note that the calculation of power consumption is not limited to the above. For example, the power consumption calculation unit 3 calculates the power consumption and regenerative power in a narrow sense in advance by multiplying uncorrected vehicle weight, acceleration (deceleration), and distance, The power consumption and regenerative power in a narrow sense calculated in advance may be corrected based on the number of passengers or the boarding rate described above. Further, for example, if there is no power running train near the train that is regenerating power, the regenerative invalid power amount may be subtracted from the calculated regenerative power amount. That is, the power consumption calculation unit 3 may add the absolute value of the regenerative power consumption according to the vehicle type and the driving condition to the power consumption in a broad sense every time a condition for regenerative invalidation is established. .

  The energy saving diagram suggestion apparatus 100 according to the present embodiment creates the number of train passengers based on the designated train diagram and entry / exit history, and considers the number of passengers (power consumption in a broad sense or narrow sense). Amount). Therefore, the calculation accuracy of the power consumption can be improved as compared with the method of calculating the power consumption without considering the passenger flow. In addition, since it is possible to comprehensively evaluate the quality of the bus schedule based on the number of passengers and the power consumption calculated accurately, it is possible to comprehensively evaluate passenger convenience and power consumption. Optimization can be expected. Moreover, since the operator can select the train for which the amount of electric power is to be reduced and the operation type to be applied, the operator's intention can be reflected in the creation of an energy saving diagram.

In the fifth embodiment, the amount of decrease in convenience calculated by the convenience calculation unit 2 is the change in time to arrive at the station per passenger when the first diagram and the second diagram are compared. It is defined as

  The amount of decrease in convenience when the thinning operation is performed as the operation type is defined as a time interval from the thinning train to the next train on the assumption that a passenger scheduled to board the thinning train rides the next train. The amount of decrease in convenience when the train shortening operation is performed as the operation type is defined as zero.

For example, the convenience calculation unit 2 may obtain the time required for the travel route from when the passenger gets on (arrives) at the boarding station until the passenger gets off at the getting-off station. Alternatively, the convenience calculator 2 calculates the travel time by adding the travel time from the platform to the exit gate to the time it takes for the passenger to get off at the departure station after the passenger arrives at the boarding station. You may ask as.

In the energy saving diagram proposing device according to the fifth embodiment, the convenience calculation unit 2 compares the first diagram and the second diagram, and changes the time of arrival at the station per passenger, resulting in a decrease in convenience. Calculate as a quantity.

  Therefore, it is possible to propose an energy saving energy diagram in which the fluctuation of the station arrival time per passenger affected by the rearrangement of diamonds is as small as possible.

<Embodiment 6>
Since the configuration of the energy saving diagram proposing device in the sixth embodiment is the same as that in any of the first to fourth embodiments, the description thereof is omitted.

<Operation>
In the sixth embodiment, the amount of decrease in convenience calculated by the convenience calculation unit 2 is the change in the time of arrival at the station of all passengers when the first diagram and the second diagram are compared. It is defined as the total amount.

  The amount of decrease in convenience when performing thinning operation as the operation type is based on the assumption that passengers scheduled to board the thinning train will board the next train, and the time interval from the thinning train to the next train and the boarding on the thinning train It is defined by the integrated value of the number of passengers. The amount of decrease in convenience when the train shortening operation is performed as the operation type is defined as zero. This is because there is no passenger arrival time variation at the station. The amount of decrease in convenience when performing parallel movement operation (early departure) as the operation type is defined by the integrated value of the time worn from the schedule for early departure and the number of passengers who got on the early departure train. The amount of decrease in convenience when performing parallel traveling operation (delayed) as the operation type is defined by the integrated value of the number of passengers who got on the delayed train and the time that arrived later than planned due to the delayed departure. The amount of decrease in convenience when performing the sleep sleeping operation as the driving type is defined by the time late arrival from the schedule for sleeping sleeping and the number of passengers on the sleeping train.

  In addition, the definition of the amount of decrease in convenience for each operation type shown here is merely an example, and is not limited to these descriptions.

  A method for calculating the amount of decrease in convenience in the fifth embodiment will be described below. Convenience calculation unit 2 obtains the time required for using the train on the travel route for the generated travel route. For example, the convenience calculation unit 2 may obtain the time required for the travel route from when the passenger gets on (arrives) at the boarding station until the passenger gets off at the getting-off station. Alternatively, the convenience calculator 2 calculates the travel time by adding the travel time from the platform to the exit gate to the time it takes for the passenger to get off at the departure station after the passenger arrives at the boarding station. You may ask as. And the statistical value (for example, average value) obtained from distribution of the travel time required in order to get out a ticket gate from a platform according to the scale and structure of an alighting station may be applied to the travel time concerned.

  Similarly, the convenience calculator 2 generates a travel route for the passengers described in the entry / exit history based on the current diagram. And the convenience calculation part 2 calculates | requires the required time required when using the train of a moving route about the produced | generated moving route. And the convenience calculation part 2 is the travel time in the diagram (that is, the second diagram) after applying the operation type, and the required time of the travel route in the diagram (that is, the first diagram) before the operation type is applied. The time required to arrive at the station is determined by comparing with the required time. And the convenience calculation part 2 calculates the total amount of the change of the station arrival time of all the affected passengers from the product of the change of the station arrival time and the number of passengers calculated by the convenience calculation part 2.

<Effect>
In the energy saving diagram proposing device according to the sixth embodiment, the convenience calculation unit 2 compares the first diagram and the second diagram, and calculates the total amount of fluctuation in the time of arrival of all passengers at the station. Calculate as the amount of decline.

  Therefore, it is possible to propose an energy-saving energy diagram in which the total amount of fluctuations in station arrival times of all passengers affected by the rearrangement of diamonds is as small as possible.

  It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
