To exemplify the learning content, the machine learning unit 152-1 uses the timetable information 131 to the predicted power supply used when outputting the change command based on the estimated power consumption, the constraint condition, and the estimated power consumption and the constraint condition. The relationship between the information 133 and the operation state actual information 134 to the change command actual information 136 is learned, and a change command is generated based on the learned result.

As a result, the judgment result of the crew and the correction result based on the environmental conditions used as the judgment material are reflected in the change command, and the efficiency of the operation of the train 110 can be improved. Further, by such learning, it is possible to carry out power saving control suitable for the operation of the train 110 regardless of the experience of the crew.

The selection command unit 153 transmits the change command generated by the command generation unit 152 to the train 110, and requests the result of acceptance (selection) of the change command by the crew (selection result request).

The display unit 160 includes a display processing unit 161 and a display device 162.

The display processing unit 161 performs processing for display in order to present information related to diamonds, electric power, etc., and change commands to the commander.

FIG. 3 is a diagram showing an example of processing for appropriately reducing the power consumption of the train group in the train operation support system 100. In FIG. 3, the train operation support system 100 is divided into a process on the operation management system 120 side (operation management system side process 300) and a process on the train 110 side (train side process 310). The processing order and contents of each will be described with reference to FIG. The process shown in FIG. 3 is carried out by the operation of the commander, the crew, etc. at predetermined cycles.

Step S301 (reading information): The operation management system 120 reads out the information (diagram information 131 to change command actual information 136, etc.) recorded in the storage unit 130. The read information is retained so that it can be referred to in each process in the operation management system 120.

Step S302: The operation management system 120 transmits a request for acquiring operation status information and device control parameter information to the train 110.

Step S311: The train 110 transmits the operation state information and the device control parameter information stored in the train 110 to the operation management system 120 based on the acquisition request transmitted in step S302. If the transmission of the acquisition request fails due to a factor such as a timeout, the retransmission process is performed after a certain cycle.

Step S303 (calculation processing of control amount and estimated power consumption): The operation management system 120 calculates the control amount of the on-board equipment 111 of the train 110 and the estimated power consumption of the train 110. The operation management system 120 calculates the control amount and the estimated power consumption amount based on the information read in step S301, the operation state information and the device control parameter information transmitted in step S311. The calculation process of the control amount and the estimated power consumption will be described later with reference to FIG.

Step S304 (Calculation of difference between planned power consumption and estimated power consumption): The operation management system 120 compares the planned power consumption with the estimated power consumption calculated in step S303, and compares the planned power consumption with the estimated power consumption. Calculate the difference with. Here, the planned power consumption is the planned power consumption when the train 110 is operating according to the operation plan, and the disordered diamond power consumption when the train 110 is not operating according to the operation plan. ..

Step S305 (calculation of change amount of operation state information, generation of change command): The operation after the change when the operation management system 120 controls the device according to the control amount (changed device control parameter information) calculated in step S303. The state information is calculated, and the amount of change between the operating state information before the change and the operating state information after the change is calculated.

Further, the operation management system 120 generates a change command based on the calculation results of step S303 and step S304. For example, the operation management system 120 controls the information indicating the difference between the planned power consumption and the estimated power consumption, the control amount of the mounted device 111 (device control parameter information after the change), and the control amount of the mounted device 111. A change command including the amount of change in the operating state information is generated.

Step S306 (Does the change command conflict with the constraint conditions?): The operation management system 120 determines whether the change command generated in step S305 does not conflict with the constraint conditions defined by the first to third conditions described later. To do. If the operation management system 120 determines that there is a conflict, the process is transferred to step S307, and if it is determined that there is no conflict, the operation management system 120 shifts the process to step S308.

The first condition is that the difference calculated in step S304 does not conflict with the upper limit value. This is managed by the train group of the entire line section and / or by train 110 so that the estimated power consumption calculated by the operation management system 120 does not greatly exceed or fall below the planned power consumption. To judge. The estimated power consumption (total power consumption) of the train group of the entire line section can be calculated from the total estimated power consumption of each train 110, and the planned power consumption of the train group of the entire line section can be calculated. It can be calculated from the total planned power consumption of the train 110.

The second condition is that the amount of change in the operating state information of the train 110 itself does not conflict with the upper limit value and the lower limit value. Here, the operating state information of the train 110 itself refers to information that does not depend on the specific on-board equipment 111 (for example, the speed of the train 110, etc.). This is determined by the change command to avoid extreme changes affecting the operation of train 110.

The third condition is that the amount of change in the adjustable device control parameter information regarding the mounted device 111 of the train 110 does not conflict with the upper limit value and the lower limit value. This is for setting, for example, the operating rate of the driving device, the number of operating devices of the driving device, the set temperature of the air conditioner, etc. within the adjustable margin, and priority is given to the adjustment of each mounted device 111 depending on the setting. It can be judged by setting the degree. Further, when there is a device or the like that is not mounted on the train 110, invalid setting can be prevented by the determination under this condition.

Here, each of the above-mentioned upper limit value and lower limit value is defined on the operation management system 120 side or the train 110 side.

Step S307 (correction of change command): When the change command conflicts with the constraint condition based on the determination in step S306, the operation management system 120 corrects the change command so as to satisfy the constraint condition.

For example, when it is determined that the control amount of the brake is maximized within the set range and the control amount of the drive device is minimized within the set range, the train 110 operates in order to avoid a sudden deceleration. The management system 120 brakes, for example, so that the amount of change in the speed of the train 110 does not conflict with the upper and lower limits and the estimated power consumption of the train 110 is reduced (for example, minimized). And / or the control amount of the drive device is corrected.

Further, for example, when it is determined that the set temperature of the first air conditioner is not controlled and the set temperature of the second air conditioner is not controlled, the occupancy rate of the train 110 is high and the outside temperature is very high. In order to avoid a situation in which the temperature inside the train 110 rises sharply, the operation management system 120 is used, for example, so that the amount of change in the temperature inside the train 110 does not conflict with the upper limit value and the lower limit value, and the train. The control amount of the first air conditioner and / or the control amount of the second air conditioner is corrected so that the estimated power consumption of 110 is reduced (for example, minimized).

Step S308: The operation management system 120 transmits the change command created as described above to the train 110.

Step S312 (output of information): After receiving the change command, the train 110 outputs the change command to the user interface unit 113. For example, the train 110 outputs the changed device control parameter information. Further, for example, the train 110 outputs information relating to the changed power consumption (for example, information indicating the difference between the planned power consumption and the estimated power consumption). Further, for example, the train 110 outputs information related to the changed operating state information (for example, the changed operating state information, the amount of change between the changed operating state information and the changed operating state information). The output may be a display by a display, an audio output by a speaker, printing on a medium such as paper, or other output. ..

Step S313 (adopt change command?): The train 110 asks the crew to select whether or not to adopt the change command, and determines whether or not the change command has been adopted. If it is determined that the train 110 has been adopted, the process is transferred to step S314, and if it is determined that the train 110 has not been adopted, the process is transferred to step S315. Here, the change command may be selected from a plurality of patterns and modes. As described above, the control may be realized by manual control by the crew by giving an operation instruction to the crew by the user interface unit 113, or by automatic control by the vehicle information control device 112. May be good.

Step S314 (control based on the change command): The train 110 controls the mounted device 111 based on the change command (according to the device control parameter information of the mounted device 111 of the train 110).

Step S315: The train 110 transmits the result of selection of the change command in step S313 to the operation management system 120.

FIG. 4 is a diagram showing an example of a flowchart relating to the calculation process of the control amount and the estimated power consumption amount. In the calculation process, the (priority 1) timetable is hindered for all trains 110 (train groups) in the line section managed by the operation management system 120, and for all the equipment 111 mounted on each train 110. The control amount for controlling is calculated within a range that does not exist and does not exceed the (priority 2) set limit value.

Step S401 (Is the trains in the line section covered?): The operation management system 120 determines whether or not all the train groups existing in the line section to be managed are processed (whether or not they are covered). When it is determined that the operation management system 120 covers the train 110, the operation management system 120 calculates the total power consumption calculated in step S403 for each device 111 mounted on the train 110 as the estimated power consumption, ends the calculation process, and does not cover the train 110. If it is determined, the unprocessed train 110 is set as the processing target (target train), and the processing is transferred to step S402.

Step S402 (whether the on-board equipment of the target train is covered?): The operation management system 120 determines whether or not all of the on-board equipment 111 of the target train have been processed (whether or not they are covered). If the operation management system 120 determines that it is covered, the process is transferred to step S408, and if it is determined that it is not covered, the mounted device 111 that is not processed is set as the processing target (target device), and step S403 is set. Move the process to.

Step S403 (calculate the control amount and power consumption amount of the target device): The operation management system 120 calculates the control amount of the target device and controls the target device corresponding to the calculated control amount. Calculate the power consumption of. More specifically, the operation management system 120 has operating state information (boarding) of the train 110 within a predetermined setting range (a range determined by the restrictions of the on-board equipment 111, a range specified by the operator, etc.). A control amount that reduces power consumption within a set range determined according to the rate, train 110 speed, outside temperature, daytime, nighttime, etc., or within the reduced setting range described later (for example). , The control amount that maximizes the reduction of power consumption within the set range) is calculated.

Step S404 (Does the timetable be affected by controlling the target device?): The operation management system 120 determines whether or not the timetable is affected by controlling the target device with the calculated control amount. When the operation management system 120 determines that the timetable is affected, the process is transferred to step S405, and when it is determined that the timetable is not affected, the operation management system 120 shifts the process to step S407.

For example, if the operation management system 120 determines that the time is delayed by a predetermined time or more from the time scheduled for the next arrival station, it determines that the timetable is affected.

Further, for example, when the control for decelerating the first train 110 is determined and the speed of the second train 110 following the first train 110 is not controlled, the first train 110 and the second train are determined. When it is determined that the distance from 110 is less than a predetermined distance, it is determined that the diamond is affected.

Step S405 (Is the influence on the timetable in the direction of returning to the planned timetable?): The operation management system 120 determines whether or not the influence on the timetable is in the direction of returning to the planned timetable. When the operation management system 120 determines that the direction is the return direction, the process shifts to step S407, and when it determines that the direction is not the return direction, the operation management system 120 shifts the process to step S406.

For example, the operation management system 120 stops the train 110 at the nearest station so that the train 110 does not stop between stations, or intentionally delays the train 110 to adjust the operation interval even when the timetable is affected. As described above, if it is the case of returning to the planned timetable side (normal operation state) from the state such as delay, it is judged that the timetable is not affected.

Step S406: The operation management system 120 reduces the setting range. In this way, when the control of the target device affects the timetable and causes a situation such as delay, the operation management system 120 reduces the setting range and executes step S403 step S405 again, so that the timetable is hindered. Determine the control amount within the range that does not exist.

Step S407: The operation management system 120 changes the target device.

Step S408: The operation management system 120 changes the target train.

In the above process, for example, when the train 110 is required to maintain the speed of the train 110 while reducing the estimated power consumption when the train 110 climbs a slope, the operation management system 120 sets the on-board equipment 111 of the train 110.
