Mode for Carrying Out the Invention

[0009] Hereinafter, an operation management system, an operation management device, an operation management method, and an operation management program according to an embodiment of the present disclosure will be described in detail with reference to the drawings.

[0010] Embodiment 1. FIG. 1 is a configuration diagram showing an operation management system according to Embodiment 1. The operation management system 101 according to Embodiment 1 manages the operations of a plurality of trains 100 in a railway. As shown in FIG. 1, the operation management system 101 according to Embodiment 1 includes an operation information server 1, a power consumption prediction unit 2, a travel instruction unit 3, and a power supply server 4.

[0011] The operation information server 1 is constituted by, for example, one or more cloud servers. A cloud server is a server constructed in a cloud environment including computer resources provided in a cloud service platform. Note that the operation information server 1 may be a server other than a cloud server, for example, an on-premises server. Further, the operation information server 1 may be configured as an operation information device together with the travel instruction unit 3 and the power consumption prediction unit 2. Further, the travel instruction unit 3 and the power consumption prediction unit 2 may be configured as one device or as separate devices. Further, the travel instruction unit 3 and the power consumption prediction unit 2 may be constituted by, for example, one or more cloud servers.

[0012] The operation information server 1 has an operation information communication unit 10 that transmits and receives operation information data of a plurality of trains 100, and an operation information storage unit 11 that stores the operation information data of the train 100. The operation information communication unit 10 is communicably connected to each of the plurality of trains 100 via a network, and receives operation information data from the plurality of trains 100. The operation information data received by the operation information communication unit 10 from the train 100 is, for example, the speed of the train 100, the acceleration and deceleration of the train 100, the time when the train 100 stops at a station, the boarding rate of passengers on the train 100, the state of on-board equipment installed on the train 100, the power consumption of the train 100, etc. Note that the operation information data received by the operation information server 1 from the plurality of trains 100 is not limited to these. Also, the operation information communication unit 10 is communicably connected to the power consumption prediction unit 2, the travel instruction unit 3, and the power supply server 4 via a network. The network is, for example, a WAN (Wide Area Network) such as the Internet, but may also be a LAN (Local Area Network).

[0013] As an example, the operation information storage unit 11 stores an on-board collection database, an OD (Origin to Destination) database, an execution schedule database, an actual schedule database, a power simulation database, and a travel instruction database. The operation information storage unit 11 stores current and past actual data. In FIG. 1, the database is denoted as DB (Data Base). The same shall apply in FIGS. 2 and later. In FIG. 1, it is assumed that six databases are stored in the operation information storage unit 11, but the operation information server 1 may be provided with a storage unit for each database.

[0014] The on-vehicle collected database stores, as an example, the speed of train 100, the acceleration and deceleration of train 100, the time when train 100 stops at a station, the boarding rate of passengers on train 100, the status of on-vehicle equipment installed on train 100, the power consumption of train 100, etc. The OD database stores data that is a type of boarding and alighting passenger data of public transportation such as railways, and aggregates data on "how many passengers boarded from a certain place and where they are going". The power simulation database stores the simulation results of the amount of power consumed by train 100. The actual operation diagram database stores the actual operation diagram data, which is the operation schedule of train 100. The actual operation diagram data is appropriately adjusted according to the operation status of train 100 and stored in the actual operation diagram database. The performance diagram database stores the diagram that train 100 actually traveled, and data indicating the result of the operation of train 100. The travel instruction database stores the travel instructions for train 100 generated by the travel instruction unit 3. Note that the operation information storage unit 11 may store operation information data of a plurality of railway operators including other operators, not limited to the operation information data of the self-operator.

[0015] The power consumption prediction unit 2 simulates the amount of power consumed by train 100 based on the operation information data stored in the operation information storage unit 11. The operation information data obtained by the power consumption prediction unit 2 is on-vehicle collected data, OD data, actual operation diagram data, and performance diagram data. The power consumption prediction unit 2 can improve the prediction accuracy by using, as on-vehicle collected data, past performance data and performance data of a plurality of railway operators including other operators. Further, when the travel instruction unit 3 generates a travel instruction, the power consumption prediction unit 2 simulates the amount of power consumed when train 100 travels according to the travel instruction. The simulation results generated by the power consumption prediction unit 2 are transmitted to the operation information server 1 and stored in the power simulation database of the operation information storage unit 11.

[0016] The travel instruction unit 3 generates a travel instruction for the running train 100 based on the operation information data stored in the operation information storage unit 11. The operation information data acquired by the travel instruction unit 3 is on-vehicle collection data, OD data, scheduled operation diagram data, actual operation diagram data, and power simulation data. The travel instruction generated by the travel instruction unit 3 is transmitted to the operation information server 1 and stored in the travel instruction database of the operation information storage unit 11. Further, the travel instruction unit 3 determines whether the power consumption of the train 100 according to the generated travel instruction exceeds a specified power consumption based on the simulation result of the power consumption prediction unit 2. When the power consumption of the train 100 according to the generated travel instruction exceeds the specified power consumption, the travel instruction unit 3 adjusts the numerical value of the parameter regarding the travel details of the train 100 and corrects the travel instruction. An example of the parameter regarding the travel details of the train 100 is the timing of acceleration and deceleration. The specified power consumption is, for example, defined by the substation 200 described later. In addition, the travel instruction unit 3 is communicably connected to each of the plurality of trains 100 via a network, and transmits the generated travel instruction to the train 100.

[0017] The power supply server 4 is composed of, for example, one or more cloud servers. The cloud server is a server constructed in a cloud environment including computer resources provided in a cloud service platform. Note that the power supply server 4 may be a server other than a cloud server, for example, an on-premises server.

[0018] The catenary server 4 gives an instruction for power supply to a catenary network in which the train 100, the substation 200, and the external equipment 300 are connected by catenary wires. The catenary server 4 has a catenary communication unit 40 and a catenary storage unit 41. The catenary communication unit 40 is communicably connected to the substation 200 and the external equipment 300 via a network, and transmits the instruction received from the operation information server 1 to the substation 200 and the external equipment 300. Further, the catenary communication unit 40 receives power information data from the substation 200 and the external equipment 300, and stores it in the catenary storage unit 41. Further, the catenary communication unit 40 transmits the power information data stored in the catenary storage unit 41 to the operation information server 1. The catenary storage unit 41 stores, as power information data, the power consumption amount defined in the substation 200 and the surplus power amount of the external equipment 300.

[0019] The substation 200 supplies power to the route section where the train 100 runs via catenary wires. For example, substation A supplies power to the first route section where the train 100 runs via catenary wires. Substation B supplies power to the second route section where the train 100 runs via catenary wires. Substation C supplies power to the third route section where the train 100 runs via catenary wires.

[0020] The external equipment 300 is, for example, a station facility and a station building auxiliary power supply device. The station facility includes a power generation device such as solar light and a charging device for electric vehicles. The station building auxiliary power supply device is an inverter device that converts the regenerative power generated by the regenerative brake of the train 100 from DC to AC so that it can be used for station lighting, air conditioning, escalators, etc. The station facility and the station building auxiliary power supply device are centrally managed for energy usage by a BEMS (Building Energy Management System).

[0021] Next, with reference to FIG. 2, the processing procedure of the operation management system 101 according to Embodiment 1 will be described. FIG. 2 is a flowchart showing the processing procedure of the operation management system according to Embodiment 1. First, the travel instruction unit 3 acquires the operation information data stored in the operation information storage unit 11 (step S101). The operation information data acquired by the travel instruction unit 3 is on-vehicle collection data, OD data, execution schedule data, actual schedule data, and power simulation data. The power simulation data is what the power consumption prediction unit 2 has previously simulated the power consumption amount of the train 100 based on the execution schedule data.

[0022] Next, the travel instruction unit 3 extracts a group consisting of a plurality of trains 100 that combines the trains 100 to be accelerated and the trains 100 to be decelerated based on the acquired operation information data (step S102). Next, the travel instruction unit 3 extracts the train 100 that delays the next station based on the acquired operation information data (step S103). The train 100 that delays the next station is the next subsequent train 100 that travels the same route as the train 100 that is stopped on the line. Note that when there is no train 100 that delays the next station, the process of step S103 may be omitted.

[0023] Next, the travel instruction unit 3 generates travel instructions for the train 100 extracted in steps S102 and S103 (step S104). For the plurality of trains 100 extracted in step S102, travel instructions indicating the timing of acceleration and deceleration are generated. At this time, for any one of the trains 100 in the group, a travel instruction indicating the timing of acceleration is generated, and for the other trains 100, a travel instruction indicating the timing of regenerative braking is generated, and together with the regenerative power generated by the regenerative braking, a travel instruction for supplying the power to the train 100 to be accelerated may be generated. The travel instruction unit 3 determines the timing of deceleration and acceleration of each train 100 in the group so that the regenerative power of the train 100 to be decelerated can be used by the train 100 to be accelerated. The operation management system 101 can suppress the power consumption of the substation 200 and achieve energy saving by increasing the utilization rate of the regenerative braking and effectively utilizing the regenerative power. Further, the travel instruction unit 3 checks the power status of the external equipment 300, and when it is likely to supply power to the external equipment 300, a travel instruction for generating regenerative power by regenerative braking and supplying it to the external equipment 300 may be generated for the train 100 that was not extracted as a group. For the train 100 extracted in step S103, a travel instruction indicating the timing of deceleration is generated to prevent unnecessary stops before arriving at the next station. Also in this case, a travel instruction for generating regenerative power using the regenerative braking and supplying it to the external equipment 300 may be generated.

[0024] Next, the travel instruction unit 3 transmits the generated travel instructions to the operation information server 1. The operation information communication unit 10 receives the travel instructions from the travel instruction unit 3 and stores them in the travel instruction database of the operation information storage unit 11 (step S105). The power consumption prediction unit 2 simulates the power consumption of the train 100 based on the travel instructions generated by the travel instruction unit 3 and generates power simulation data (step S106). Next, the power consumption prediction unit 2 transmits the generated power simulation data to the operation information server 1. The operation information communication unit 10 receives the power simulation data from the power consumption prediction unit 2 and stores it in the power simulation database of the operation information storage unit 11 (step S107).

[0025] Next, the travel instruction unit 3 acquires power simulation data from the operation information storage unit 11 (step S108), and determines whether there is a substation 200 that exceeds a specified power consumption amount in the acquired power simulation data (step S109). When the travel instruction unit 3 determines that there is no substation 200 that exceeds the specified power consumption amount in the power simulation data (step S109: Yes), it transmits the generated travel instruction to the train 100 (step S110) and ends the process.

[0026] On the other hand, when the travel instruction unit 3 determines that there is a substation 200 that exceeds the specified power consumption amount in the acquired power simulation data (step S109: No), it adjusts the numerical value of the parameter regarding the travel content of the train 100 so as not to exceed the power consumption amount specified by the substation 200, and modifies the travel instruction (step S111). The parameter regarding the travel content of the train 100 is the timing of acceleration and deceleration. Then, the travel instruction unit 3 transmits the modified travel instruction to the operation information server 1. The operation information communication unit 10 receives the travel instruction from the travel instruction unit 3 and stores it in the travel instruction database of the operation information storage unit 11 (step S105). The power consumption prediction unit 2 simulates the power consumption amount of the train 100 again based on the modified travel instruction (step S106).

[0027] Next, with reference to FIG. 3, the processing procedure performed by the travel instruction unit 3 in step S102 of the flowchart shown in FIG. 2 will be described. FIG. 3 is a flowchart showing a processing procedure for extracting a group consisting of a plurality of trains combined with a train to be accelerated and a train to be decelerated in the travel instruction unit included in the operation management system according to the first embodiment.

[0028] First, the travel instruction unit 3 selects one train 100 that is present on the same overhead line, and extracts a plurality of other trains 100 within a certain distance from the station at the time when the selected train 100 arrives at or departs from the station (step S120). Next, based on the actual operation timetable data, the travel instruction unit 3 extracts, for the departure time of the station in the selected one train 100, the trains 100 among the plurality of trains 100 extracted in step S120 whose arrival times are within a certain number of minutes, or for the arrival time of the station in the selected one train 100, the trains 100 among the plurality of trains 100 extracted in step S120 whose departure times are within a certain number of minutes (step S121). That is, in steps S120 and S121, for the selected one train 100, other trains 100 that are close in distance and have close arrival and departure times are extracted. Then, the travel instruction unit 3 extracts the selected one train 100 and another train 100 extracted in step S121 as one group, that is, extracts a group consisting of a plurality of trains 100 that are a combination of the train to be accelerated and the train to be decelerated, and excludes the extracted trains 100 from the candidates within the loop (step S122). After the travel instruction unit 3 loops the processes from step S120 to step S122 by the number of trains 100 present in the line section, it determines that the remaining trains 100 are trains 100 that do not need to combine acceleration and deceleration.

[0029] Next, with reference to FIG. 4, the processing procedure performed by the travel instruction unit 3 in step S103 of the flowchart shown in FIG. 2 will be described. FIG. 4 is a flowchart showing the processing procedure for extracting the train that delays the next station in the travel instruction unit of the operation management system according to the first embodiment. First, the travel instruction unit 3 extracts the trains 100 that have a delay and are stopped on the line due to the influence among the trains 100 present (step S130). Next, the travel instruction unit 3 extracts one subsequent train 100 that travels the same route as the extracted train 100 (step S131). The travel instruction unit 3 loops the processes from step S130 to step S131 by the number of trains present.

[0030] Next, with reference to FIG. 5, the processing procedure performed by the power consumption prediction unit 2 in step S106 of the flowchart shown in FIG. 2 will be described. FIG. 5 is a flowchart showing the processing procedure of the power consumption prediction unit included in the operation management system according to the first embodiment.

[0031] First, the power consumption prediction unit 2 acquires the operation information data stored in the operation information storage unit 11 (step S140). Next, the power consumption prediction unit 2 reproduces the current route situation on the simulator based on the acquired operation information data (step S141). The route situation is, for example, the position of the train 100, the speed of the train 100, the time when the train 100 stops at the station, the power consumption of the train 100, and the like. Next, the power consumption prediction unit 2 stores the power consumption amount of the train 100 in the route at the current time on the simulator (step S142). Next, the power consumption prediction unit 2 reflects the travel instruction generated by the travel instruction unit 3 on the simulator (step S143). The power consumption prediction unit 2 predicts the power consumption amount from the current time to the specified time based on the stored power consumption amount at the current time, and generates power simulation data (step S144). In the travel instruction generated by the travel instruction unit 3, when the regenerative power of the train 100 to be decelerated is supplied to the train 100 to be accelerated, the regenerative power is considered in the prediction of the power consumption amount. Then, the power consumption prediction unit 2 transmits the generated power simulation data to the operation information server 1 (step S145).

[0032] As described above, the operation management system 101 according to Embodiment 1 includes an operation information server 1 having an operation information storage unit 11 in which operation information data of the train 100 is stored, and based on the operation information data stored in the operation information storage unit 11, a power consumption prediction unit 2 that simulates the amount of power consumed by the train 100, and a travel instruction unit 3 that generates a travel instruction for the train 100 based on the simulation result of the power consumption prediction unit 2 and the operation information data stored in the operation information storage unit 11. Therefore, the operation management system 101 according to Embodiment 1 generates a travel instruction for reducing the power consumption amount for the actually operating train 100 based on the simulation result of the power consumption prediction unit 2, so that energy saving can be achieved.

[0033] Embodiment 2. Next, the operation management system according to Embodiment 2 will be described. In Embodiment 2, the same components as those in Embodiment 1 are denoted by the same reference numerals, and the configuration different from that in Embodiment 1 will be mainly described.

[0034] In the operation management system according to Embodiment 2, in the configuration of the operation management system 101 described in Embodiment 1 above, when the travel instruction unit 3 repeatedly generates a travel instruction but exceeds the power consumption amount specified at the substation 200, the power supply server 4 is characterized by instructing to supply the surplus power of the external equipment 300 to the substation 200. The external equipment 300 may have surplus power by power generated by the power generation device of the station facility and regenerative power supplied from the train 100, etc. Hereinafter, with reference to FIG. 6, the processing procedure of the operation management system 101 according to Embodiment 2 will be described. FIG. 6 is a flowchart showing the processing procedure of the operation management system according to Embodiment 2. Note that Steps S201 to S208 are the same as the processing of Steps S101 to S108 in Embodiment 1, and thus the description thereof will be omitted.

[0035] The travel instruction unit 3 determines whether there is a substation 200 that exceeds the specified power consumption amount in the power simulation data acquired from the operation information storage unit 11 in step S208 (step S209). When the travel instruction unit 3 determines that there is no substation 200 that exceeds the specified power consumption amount in the power simulation data (step S209: Yes), it transmits the generated travel instruction to the train 100 (step S210) and ends the process.

[0036] On the other hand, when the travel instruction unit 3 determines that there is a substation 200 that exceeds the specified power consumption amount in the power simulation data acquired from the operation information storage unit 11 in step S208 (step S209: No), it determines whether the number of times of checking the power consumption amount exceeds a preset number of times (step S211). When the travel instruction unit 3 determines that the number of times of checking the power consumption amount does not exceed the preset number of times (step S211: No), it adjusts the numerical values of the parameters related to the travel content of the train 100 so as not to exceed the specified power consumption amount at the substation 200 and corrects the travel instruction (step S212). The parameters related to the travel content of the train 100 are the timings of acceleration and deceleration. Then, the travel instruction unit 3 transmits the corrected travel instruction to the operation information server 1. The operation information communication unit 10 receives the travel instruction from the travel instruction unit 3 and stores it in the travel instruction database of the operation information storage unit 11 (step S213). The power consumption prediction unit 2 simulates the power consumption amount of the train 100 again based on the corrected travel instruction (step S206).

[0037] On the one hand, when the travel instruction unit 3 determines that the number of times of checking the power consumption amount exceeds a preset number of times (step S211: Yes), it instructs the power consumption prediction unit 2 via the operation information server 1 to perform a power simulation when using the surplus power of the external device 300 (step S214). The power consumption prediction unit 2 simulates the power consumption amount when using the surplus power of the external device 300 in the travel instruction generated by the travel instruction unit 3 and generates power simulation data (step S206). The power consumption prediction unit 2 transmits the generated power simulation data to the operation information server 1. The operation information communication unit 10 receives the power simulation data from the power consumption prediction unit 2 and stores it in the power simulation database of the operation information storage unit 11 (step S207). When the travel instruction unit 3 acquires the power simulation data from the operation information storage unit 11 (step S208) and determines that there is no substation 200 where the simulation result of the power consumption prediction unit 2 exceeds the specified power consumption amount (step S209: Yes), it transmits the generated travel instruction to the train 100. In addition, the travel instruction unit 3 transmits an instruction to supply the surplus power of the external device 300 to the substation 200 to the power supply server 4 via the operation information server 1. The external device 300 that has received the instruction from the power supply server 4 supplies power to the substation 200 that supplies power to the train 100 with power exceeding the specified power consumption amount among the plurality of substations 200. At this time, the power supply server 4 may instruct the external device 300 not to supply surplus power during a time period when the power consumption amount specified for the substation 200 is not exceeded, and to supply surplus power during a time period when the power consumption amount specified for the substation 200 is exceeded.

[0038] Next, with reference to FIG. 7, the processing procedure of simulating the power consumption amount when using the surplus power of the external device 300 in step S206 of the flowchart shown in FIG. 6 will be described. FIG. 7 is a flowchart showing the processing procedure of the power consumption prediction unit included in the operation management system according to Embodiment 2.

[0039] First, the power consumption prediction unit 2 acquires the operation information data stored in the operation information storage unit 11 (step S220). Next, the power consumption prediction unit 2 reproduces the current route situation on the simulator based on the acquired operation information data (step S221). The route situation is, for example, the position of the train 100, the speed of the train 100, the time when the train 100 stops at the station, the power consumption of the train 100, and so on. Next, the power consumption prediction unit 2 stores the power consumption amount of the train 100 in the route at the current time on the simulator (step S222). Next, the power consumption prediction unit 2 reflects the driving instruction generated by the driving instruction unit 3 on the simulator (step S223). When the power consumption prediction unit 2 receives power supply from the external device 300, it reflects the power supply amount (step S224). The power consumption prediction unit 2 predicts the power consumption amount from the current time to the specified time based on the stored power consumption amount at the current time, and generates power simulation data (step S225). Then, the power consumption prediction unit 2 transmits the generated power simulation data to the operation information server 1 (step S226).

[0040] As described above, in the operation management system according to the second embodiment, in addition to the configuration of the first embodiment, a power supply server 4 for instructing power supply is provided in the power network in which the train 100, the substation 200, and the external device 300 are connected by power lines. When the power consumption amount of the train 100 that has received the driving instruction corrected by the driving instruction unit 3 exceeds the specified power consumption amount, the power consumption prediction unit 2 simulates the power consumption amount in the driving instruction when using the surplus power of the external device 300. Based on the simulation result of the power consumption prediction unit 2, the power supply server 4 instructs the external device 300 to supply the surplus power to the substation 200 where the power is insufficient.

[0041] Therefore, when the power consumption of the train 100 that has received the travel instruction modified by the travel instruction unit 3 exceeds the specified power consumption in the operation management system according to the second embodiment, the power supply server 4 instructs the external equipment 300 to supply surplus power to the substation 200 where power is insufficient. As a result, the power consumption of the substation 200 can be adjusted to be equal to or less than the specified power consumption, and energy conservation can be achieved.

[0042] Embodiment 3. Next, the operation management system 102 according to the third embodiment will be described. In the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the configuration different from that in the first embodiment will be mainly described.

[0043] FIG. 8 is a configuration diagram showing the operation management system according to the third embodiment. As shown in FIG. 8, the operation management system 102 according to the third embodiment includes a train schedule adjustment unit 5 in addition to the configuration of the operation management system 101 described in the first embodiment.

[0044] When the power consumption of the train 100 that has received the travel instruction modified by the travel instruction unit 3 exceeds the specified power consumption, the train schedule adjustment unit 5 adjusts the schedule of the pre-set actual execution schedule data based on the operation information data stored in the operation information storage unit 11. The schedule adjustment is performed according to parameters pre-set by the user. The parameters are, for example, the allowable time for delaying the schedule, the allowable number of trains 100 to be cancelled, etc. The actual execution schedule data adjusted by the train schedule adjustment unit 5 is transmitted to the operation information server 1 and stored in the actual execution schedule database of the operation information storage unit 11.

[0045] The train schedule adjustment unit 5 may be configured as one device together with the travel instruction unit 3 and the power consumption prediction unit 2, or may be configured as separate devices. Further, the train schedule adjustment unit 5 may be configured as an operation information device together with the operation information server 1, the travel instruction unit 3, and the power consumption prediction unit 2. Further, the train schedule adjustment unit 5 may be configured by, for example, one or more cloud servers.

[0046] Next, with reference to FIG. 9, the processing procedure of the operation management system 102 according to Embodiment 3 will be described. FIG. 9 is a flowchart showing the processing procedure of the operation management system according to Embodiment 3. Note that steps S301 to S308 are the same as steps S101 to S108 in Embodiment 1, and thus the description thereof is omitted.

[0047] The travel instruction unit 3 determines whether there is a substation 200 that exceeds a specified power consumption amount in the power simulation data acquired from the operation information storage unit 11 in step S308 (step S309). When the travel instruction unit 3 determines that there is no substation 200 that exceeds the specified power consumption amount in the power simulation data (step S309: Yes), it transmits the generated travel instruction to the train 100 (step S310) and ends the process.

[0048] On the other hand, when the travel instruction unit 3 determines that there is a substation 200 that exceeds the specified power consumption amount in the power simulation data acquired from the operation information storage unit 11 in step S308 (step S309: No), it determines whether the number of times of checking the power consumption amount exceeds a preset number of times N1 (step S311). When the travel instruction unit 3 determines that the number of times of checking the power consumption amount does not exceed the preset number of times N1 (step S311: No), it adjusts the numerical value of the parameter related to the travel content of the train 100 so as not to exceed the specified power consumption amount at the substation 200, and corrects the travel instruction (step S312). The parameter related to the travel content of the train 100 is the timing of acceleration and deceleration. Then, the travel instruction unit 3 transmits the corrected travel instruction to the operation information server 1. The operation information communication unit 10 receives the travel instruction from the travel instruction unit 3 and stores it in the travel instruction database of the operation information storage unit 11 (step S305). The power consumption prediction unit 2 simulates the power consumption amount of the train 100 again based on the corrected travel instruction (step S306).

[0049] On the other hand, when the travel instruction unit 3 determines that the number of times the power consumption is checked exceeds a preset number N1 (step S311: Yes), it determines whether the number of times the power consumption is checked exceeds a preset number N2 (step S313). N2 is a numerical value larger than N1. When the travel instruction unit 3 determines that the number of times the power consumption is checked does not exceed the preset number N2 (step S313: No), it instructs the train schedule adjustment unit 5 to adjust the train schedule of the train 100 via the operation information server 1 (step S314). That is, the travel instruction unit 3 determines that the power consumption of the train 100 does not fall within the power consumption specified by the substation 200 even if the travel instructions are repeatedly generated, and issues an instruction to the train schedule adjustment unit 5 to adjust the actual execution schedule data.

[0050] The train schedule adjustment unit 5 adjusts the actual execution schedule data of the extracted train 100 based on the operation information data stored in the operation information storage unit 11 and transmits it to the operation information server 1. The operation information communication unit 10 stores the actual execution schedule data received from the train schedule adjustment unit 5 in the actual execution schedule database of the operation information storage unit 11 (step S315).

[0051] Then, based on the actual execution schedule data adjusted by the train schedule adjustment unit 5, the travel instruction unit 3 adjusts the numerical values of the parameters related to the travel content of the train 100 so as not to exceed the power consumption specified by the substation 200, and corrects the travel instruction (step S316). Then, the travel instruction unit 3 transmits the corrected travel instruction to the operation information server 1. The operation information communication unit 10 receives the travel instruction from the travel instruction unit 3 and stores it in the travel instruction database of the operation information storage unit 11 (step S305). The power consumption prediction unit 2 simulates the power consumption of the train 100 again based on the corrected travel instruction (step S306).

[0052] On the other hand, when the travel instruction unit 3 determines that the number of times of checking the power consumption exceeds a predetermined number of times N2 (step S313: Yes), it determines that it is impossible to further reduce the power consumption, and finally transmits a travel instruction based on the actual execution train operation schedule data adjusted by the train operation schedule adjustment unit 5 to the train 100 (step S310), and ends the process.

[0053] Next, with reference to FIG. 10, the processing procedure performed by the train operation schedule adjustment unit 5 in step S314 of the flowchart shown in FIG. 9 will be described. FIG. 10 is a flowchart showing the processing procedure of the train operation schedule adjustment unit included in the operation management system according to Embodiment 3. First, the train operation schedule adjustment unit 5 acquires the power simulation data stored in the operation information storage unit 11 (step S320). Next, the train operation schedule adjustment unit 5 extracts, based on the power simulation data, the substations 200 that exceed the specified power consumption amount among the plurality of substations 200 (step S321). Then, among the plurality of trains 100 traveling on the line section supplied with power from the extracted substations 200, the trains 100 with a large power consumption amount are extracted (step S322). Next, the train operation schedule adjustment unit 5 determines the delay and cancellation of the train operation schedule according to the parameters preset by the user (step S323). The parameters are, for example, the allowable time for delaying the train operation schedule and the allowable number of trains 100 to be cancelled. Then, the train operation schedule adjustment unit 5 acquires the actual execution train operation schedule data from the actual execution train operation schedule database and adjusts the actual execution train operation schedule (step S324).

[0054] As described above, in the operation management system 102 according to Embodiment 3, in addition to the configuration of Embodiment 1, when the power consumption amount of the train 100 that has received the travel instruction corrected by the travel instruction unit 3 exceeds the specified power consumption amount, based on the operation information data stored in the operation information storage unit 11, it is provided with a train operation schedule adjustment unit 5 that adjusts the actual execution train operation schedule of the preset train 100. The travel instruction unit 3 corrects the travel instruction based on the actual execution train operation schedule adjusted by the train operation schedule adjustment unit 5. The power consumption prediction unit 2 simulates again the power consumption amount of the train 100 based on the travel instruction corrected by the travel instruction unit 3 based on the actual execution train operation schedule.

[0055] Therefore, even if the travel instruction unit 3 repeatedly corrects the travel instruction, when the power consumption of the train 100 exceeds the specified power consumption in the operation management system 102 according to the third embodiment, the train operation adjustment unit 5 corrects the travel instruction so as not to exceed the power consumption based on the implemented operation diagram adjusted by the train operation adjustment unit 5, so that energy saving can be achieved.

[0056] Embodiment 4. Next, the operation management system according to the fourth embodiment will be described. In the fourth embodiment, the same components as those in the third embodiment are denoted by the same reference numerals, and the components different from those in the third embodiment will be mainly described.

[0057] In the operation management system according to the fourth embodiment, in the configuration of the operation management system 102 described in the third embodiment, even if the travel instruction unit 3 repeatedly generates travel instructions, when the power consumption exceeds the power consumption specified at the substation 200, the power supply server 4 instructs the external equipment 300 to supply the surplus power to the substation 200. The external equipment 300 may have surplus power due to power generated by the power generation device of the station facility, regenerative power supplied from the train 100, and the like. Hereinafter, with reference to FIG. 11, the processing procedure of the operation management system according to the fourth embodiment will be described. FIG. 11 is a flowchart showing the processing procedure of the operation management system according to the fourth embodiment. Since steps S401 to S408 are the same as steps S301 to S308 in the third embodiment, the description thereof will be omitted.

[0058] The travel instruction unit 3 determines whether there is a substation 200 that exceeds the specified power consumption in the power simulation data acquired from the operation information storage unit 11 in step S408 (step S409). When the travel instruction unit 3 determines that there is no substation 200 that exceeds the specified power consumption in the power simulation data (step S409: Yes), the generated travel instruction is transmitted to the train 100 (step S410), and the process ends.

[0059] On the other hand, when the traveling instruction unit 3 determines that there is a substation 200 exceeding the specified power consumption amount in the power simulation data acquired from the operation information storage unit 11 in step S408 (step S409: No), it determines whether the number of times of checking the power consumption amount exceeds a preset number of times N1 (step S411). When the traveling instruction unit 3 determines that the number of times of checking the power consumption amount does not exceed the preset number of times N1 (step S411: No), it adjusts the numerical values of the parameters related to the traveling content of the train 100 so as not to exceed the specified power consumption amount at the substation 200, and corrects the traveling instruction (step S412). The parameters related to the traveling content of the train 100 are the timings of acceleration and deceleration. Then, the traveling instruction unit 3 transmits the corrected traveling instruction to the operation information server 1. The operation information communication unit 10 receives the traveling instruction from the traveling instruction unit 3 and stores it in the traveling instruction database of the operation information storage unit 11 (step S413). The power consumption prediction unit 2 simulates the power consumption amount of the train 100 again based on the corrected traveling instruction (step S406).

[0060] When the travel instruction unit 3 determines that the number of times of checking the power consumption amount exceeds a preset number of times N1 (step S411: Yes), it determines whether the number of times of checking the power consumption amount exceeds a preset number of times N2 (step S414). N2 is a numerical value larger than N1. When the travel instruction unit 3 determines that the number of times of checking the power consumption amount does not exceed the preset number of times N2 (step S414: No), it instructs the power consumption prediction unit 2 via the operation information server 1 to perform a power simulation when using the surplus power of the external device 300 (step S415). The power consumption prediction unit 2 simulates the power consumption amount when using the surplus power of the external device 300 in the travel instruction generated by the travel instruction unit 3 according to the processing procedure shown in FIG. 7, and generates power simulation data (step S406). The power consumption prediction unit 2 transmits the generated power simulation data to the operation information server 1. The operation information communication unit 10 receives the power simulation data from the power consumption prediction unit 2 and stores it in the power simulation database of the operation information storage unit 11 (step S407). The travel instruction unit 3 acquires the power simulation data from the operation information storage unit 11 (step S408). When it determines that there is no substation 200 whose simulation result of the power consumption prediction unit 2 exceeds the specified power consumption amount (step S409: Yes), it transmits the generated travel instruction to the train 100 (step S410). Further, the travel instruction unit 3 transmits an instruction to supply the surplus power of the external device 300 to the substation 200 to the power supply server 4 via the operation information server 1. The external device 300 that has received the instruction from the power supply server 4 supplies power to the substation 200 that supplies power exceeding the specified power consumption amount among the plurality of substations 200. At this time, the power supply server 4 may instruct the external device 300 not to supply surplus power during a time period when the specified power consumption amount of the substation 200 is not exceeded, and to supply surplus power during a time period when the specified power consumption amount of the substation 200 is exceeded.

[0061] When the traveling instruction unit 3 determines that the number of times of checking the power consumption exceeds a preset number N2 (step S414: Yes), it determines whether the number of times of checking the power consumption exceeds a preset number N3 (step S416). N3 is a numerical value larger than N2. When the traveling instruction unit 3 determines that the number of times of checking the power consumption does not exceed the preset number N3 (step S416: No), it instructs the train schedule adjustment unit 5 to adjust the train schedule of the train 100 via the operation information server 1. That is, the traveling instruction unit 3 determines that the power consumption of the train 100 cannot be within the specified power consumption of the substation 200 even if the traveling instructions are repeatedly generated, and issues an instruction to the train schedule adjustment unit 5 to adjust the actual execution schedule data.

[0062] Based on the operation information data stored in the operation information storage unit 11, the train schedule adjustment unit 5 adjusts the actual execution schedule data of the extracted train 100 and transmits it to the operation information server 1 (step S417). Step S417 is performed according to the processing procedure shown in FIG. 10. The operation information communication unit 10 stores the actual execution schedule data received from the train schedule adjustment unit 5 in the actual execution schedule database of the operation information storage unit 11 (step S418).

[0063] Then, based on the actual execution schedule data adjusted by the train schedule adjustment unit 5, the traveling instruction unit 3 adjusts the numerical values of the parameters related to the traveling content of the train 100 so as not to exceed the specified power consumption at the substation 200, and corrects the traveling instruction (step S419). Then, the traveling instruction unit 3 transmits the corrected traveling instruction to the operation information server 1. The operation information communication unit 10 receives the traveling instruction from the traveling instruction unit 3 and stores it in the traveling instruction database of the operation information storage unit 11 (step S420). The power consumption prediction unit 2 simulates the power consumption of the train 100 again based on the corrected traveling instruction according to the processing procedure shown in FIG. 7 (step S406).

[0064] On the other hand, when the travel instruction unit 3 determines that the number of times of checking the power consumption exceeds a prescribed number N3 (step S416: Yes), it determines that it is impossible to further reduce the power consumption, and finally transmits a travel instruction based on the actual operation schedule data adjusted by the schedule adjustment unit 5 to the train 100 (step S410), and ends the process.

[0065] As described above, in the operation management system according to the fourth embodiment, in addition to the configuration of the third embodiment, a power supply server 4 for instructing power supply is provided in the power network in which the train 100, the substation 200, and the external equipment 300 are connected by the power line. When the power consumption prediction unit 2 simulates the power consumption when the external equipment 300 uses surplus power, and the power consumption of the train 100 exceeds the prescribed power consumption in the travel instruction generated by the travel instruction unit 3, the schedule adjustment unit 5 adjusts the actual operation schedule of the train 100 set in advance based on the operation information data stored in the operation information storage unit 11. The travel instruction unit 3 corrects the travel instruction based on the actual operation schedule adjusted by the schedule adjustment unit 5. The power consumption prediction unit 2 simulates the power consumption of the train 100 based on the travel instruction corrected by the travel instruction unit 3 based on the actual operation schedule.

[0066] Therefore, in the operation management system according to the fourth embodiment, even if the travel instruction unit 3 repeatedly corrects the travel instruction, when the power consumption of the train 100 exceeds the prescribed power consumption, the external equipment 300 is instructed to supply surplus power to the substation 200 where power is insufficient, so that the power consumption of the substation 200 can be adjusted to be equal to or less than the prescribed power consumption, and energy saving can be achieved. Further, in the operation management system according to the fourth embodiment, as a result of simulating the power consumption when the surplus power of the external equipment 300 is used, when the power consumption of the train 100 exceeds the prescribed power consumption in the travel instruction generated by the travel instruction unit 3, the travel instruction is corrected based on the actual operation schedule adjusted by the schedule adjustment unit 5 so as not to exceed the power consumption, so that energy saving can be achieved.
