Description

The present invention generally relates to techniques for providing information on facilities affected by inundation.

In railway transportation services that carry a large number of passengers, safe operation is the first priority, but if a planned suspension of operations is carried out easily in the event of a disaster, the service level will decline. However, it is not easy for the commander to make a clear judgment between "must stop" and "must stop". It is because the factors that are the basis of judgment are external factors such as weather information and typhoon information, and internal factors such as area, station, train position, operation schedule (hereinafter referred to as "diagram"), and personnel. Is the cause. Therefore, there is a need for a system that can support planning, operation control, etc. that can visualize such external and internal factors.

In recent years, a technique for predicting inundation due to flood inundation has been disclosed (see Patent Document 1). In Patent Document 1, the time length from the start of the embankment to the start of inundation calculated in advance for each assumed embankment point is added to the predicted time of the start of the embankment, and the inundation start for each assumed embankment point is started. A program that calculates the estimated time for each region is disclosed.

FIG. 11 is a diagram showing an example of the inundation prediction route map drawing process 1100. In the inundation prediction route map drawing process 1100, drawing is performed on the route map based on the inundation prediction data continuously accumulated in the data server 210. The inundation prediction route map drawing process 1100 is automatically executed at regular intervals such as 5 minutes, 10 minutes, 30 minutes, etc., or is executed at the timing instructed by the system operator 241, staff members 281, commanders, etc. It shall be done.

First, the calculation server 220 refers to the date and time information, and acquires data from the current time of the day to be predicted to (current time + predetermined time T) in S1110 to S1130. The time zone to be predicted may be set using a predetermined fixed value such as, for example, 15 minutes, 30 minutes, 1 hour, past time, etc., with the current time as the base point. It may be arbitrarily set each time.

In S1110, the calculation server 220 (inundation prediction data route map drawing program) is an area (target) designated via a screen (for example, screen 1400 described later) displayed on the computer 240, the operation management center 274, the terminal 280, and the like. The inundation prediction data of the area) is acquired from the storage device 203-1.

In S1120, the calculation server 220 (inundation prediction data route map drawing program) is a route (target) designated via a screen (for example, screen 1400 described later) displayed on the computer 240, the operation management center 274, the terminal 280, and the like. The timetable data of the route) and the train position data of the train 260 operating on the target route are acquired from the storage device 203-1.

In S1130, the calculation server 220 (flood prediction data route map drawing program) acquires the congestion prediction data on the target route from the storage device 203-1.

In S1140, the calculation server 220 executes data processing for drawing the data acquired in S1110 to S1130.

In S1141, the calculation server 220 (inundation prediction data conversion program) converts the inundation prediction data acquired in S1110 into a data format that can be drawn on the route map. For example, the calculation server 220 associates the mesh of the inundation prediction data with the mesh of the route map, plots the inundation prediction (inundation level, inundation depth, etc.) for each time, and generates the mesh data on the route map. An example of a method for generating mesh data will be described later with reference to FIG.

In S1142, the calculation server 220 (train position timetable data conversion program) converts the train position data acquired in S1120 into a data format that can be drawn on the route map. For example, the calculation server 220 converts the kilometer data of the train position data into latitude / longitude data by using a conversion table for converting the kilometer data into latitude / longitude data, and converts the latitude and longitude of the route map into the train position. The latitude and longitude of the data are associated with each other, and data for plotting the position of the train 260 on the route map for each time is generated. In addition, when the train 260 is provided with a GPS (Global Positioning System) or the like and the position data is received from the train 260 as latitude and longitude data, conversion using a conversion table is unnecessary.

In S1143, the calculation server 220 (congestion prediction data conversion program) converts the congestion prediction data acquired in S1130 into a data format capable of drawing a map on the route map. For example, the calculation server 220 converts the kilometer data of the congestion prediction data into latitude / longitude data by using a conversion table for converting the kilometer data into latitude / longitude data, and converts the congestion prediction into the latitude and longitude of the route map. The latitude and longitude of the data are matched, and data for plotting the congestion level on the route map for each time at the position of the train 260 or the position of the station is generated.
