In order to detect such an abnormal operation and to display the situation, it is necessary to acquire standard operating speed data and standard operating route data for each route and each operating condition in advance and to make a database. The operation for this is the creation operation of the standard operation management database. Hereinafter, the operation of creating the standard operation management database will be described, and then the operation abnormality monitoring operation will be described.

(1) Operation for Creating Standard Operation Management Database FIG. 4 is a flowchart showing the operation for creating the standard operation management database. The operation of creating the standard operation management database is performed by performing a trial operation of the train 200 before operating the train operation management system 100. First, when the test operation of the train 200 starts, the train 2
The GPS 210 mounted on 00 determines the latitude, longitude, radio wave reception time, and the like at the current position based on the radio waves received from the GPS satellites, and outputs them to the calculation unit 221 as GPS data (step a1).

The operation speed calculation unit 221a is provided with a GPS 210
A calculation is performed to obtain the driving speed data based on the GPS data obtained from (step b1). FIGS. 5A and 5B illustrate the calculation of the operating speed.
As illustrated in FIG. 5A, the operation speed calculation unit 221a
Are sequentially supplied to the current time at the time of occurrence of the GPS data and the train 200 at that time.
Including the latitude and longitude of the location. Therefore, the driving speed calculation unit 221a calculates the difference between each current time included in both GPS data for each set of two consecutive GPS data, and also calculates the position represented by the GPS data that is temporally previous. From the GPS data to the position represented by the GPS data at a later time, and the driving speed is derived by dividing the latter displacement by the difference of the former. As a result, time-series operating speed data reflecting a temporal change in the operating speed is obtained. FIG. 5B is a speed transition graph showing an image of the operation speed data.

On the other hand, the driving route diagram creating unit 221b
Driving route data is created based on the GPS data acquired from S210 (step b2). FIG.
(C) shows the process of creating the driving route data. In this process, the latitude and longitude information of the current position as shown in FIG. 6A is extracted from the GPS data. As shown in FIG. 6B, the time-series latitude / longitude information itself approximates the operation route of the train 200 by a polygonal line. Therefore, this time-series latitude / longitude information may be used as driving route data. On the other hand, when accurate driving route data is required, as illustrated in FIG.
A curve that passes through a plurality of points specified by the time-series latitude / longitude information is obtained, and information indicating the curve is used as driving route data. The driving speed data and the driving route data generated by the calculation unit 221 are stored in the first storage unit 231.

Next, the standard operation speed database creation unit 2
The step 22a creates standard operating speed data and registers it in the standard operating speed database in the second storage unit 232 (step c1). In addition, the standard driving route database creation unit 222b creates the standard driving route data and performs
The registration in the standard driving route database in the storage unit 232 is performed (step c2). Further, the threshold value creation unit 250 calculates a first threshold value corresponding to the standard driving speed data and a second threshold value corresponding to the standard driving route data, and registers the first threshold value in the standard driving speed database and the standard driving route database, respectively. (Step b3). Here, the standard operating speed data is obtained by statistically adding a predetermined number of past operating speed data obtained by each test operation having the same route and operating conditions as the current test operation among the operation speed data stored in the first storage unit 231. It is determined by performing processing. Similarly, the standard driving route data is obtained by statistically adding a predetermined number of past driving route data obtained by each test driving having the same route and operating conditions as the current test driving among the driving route data stored in the first storage unit 231. It is determined by performing processing.

The reason why the standard operating speed data and the standard operating route data are obtained from the plurality of operating speed data and the plurality of operating route data is as follows. That is, the driving speed data and the driving route data are obtained from the GPS data.
The S data includes an error, and the GPS data obtained from the GPS varies even at the same position. If the driving speed data and the driving route data obtained from the GPS data including such an error are used as they are as the standard driving speed data and the standard driving route data, the driving in the normal range is performed, This is because a situation may occur in which the standard operation speed data or the standard operation route data serving as the reference is biased, and the operation is determined to be abnormal.

FIG. 7A is a diagram showing an example of the standard operation speed data registered in the standard speed database by the operation speed database creation section 222a. As shown in FIG. 7A, the standard driving speed data includes information specifying a driving route including a route name, a departure station name, and a destination station name, in addition to a speed graph indicating a temporal change of the driving speed. . The standard operation speed data includes information on operation conditions including a characteristic 1 (rush hour or normal time) and a characteristic 2 (holiday or weekday). The distance between stations is the traveling distance from the departure station to the arrival station, the required time between stations is the travel time when traveling from the departure station to the arrival station, and the average speed is the distance between the stations. Running train 200
Shows the average speed.

FIGS. 7B and 7C are diagrams showing the relationship between the standard operation speed data and the first threshold value created by the threshold value creation unit 250. FIG. In FIG. 7B, the horizontal axis represents the elapsed time from the start of operation, and the vertical axis represents the operation speed. VS is the standard operating speed data, VMAX is the upper limit of the distribution of the operating speed data used for calculating the standard operating speed data, and VMIN is the lower limit of the distribution of the operating speed data used for calculating the standard operating speed data. ing. The first threshold value is, for example, three times the standard deviation of the speed value of the operation speed data, and is obtained at each time after the start of operation.
FIG. 7C is a histogram showing the distribution of the speed values of all the driving speed data used in the calculation of the standard driving speed data, focusing on a certain time. At this time, if the operating speed data within the allowable range of the standard operating speed data ± the first threshold is detected, it is determined that the operation is normal, and the operating speed data out of the allowable range (the operating speed distribution of the operating speed distribution). If a black bottom portion is detected, it is determined that the operating speed is abnormal.

FIG. 8A is a diagram showing an example of standard driving route data registered in the standard route database by the driving route database creating section 222b. As shown in the figure, the standard driving route data includes information specifying a route including a route name, a departure station name, and a destination station name, in addition to the coordinate values of each passing position on the route. FIGS. 8B and 8C are diagrams illustrating the relationship between the standard driving route data and the second threshold value created by the threshold value creation unit 250. FIG. In FIG. 8B, LS represents a standard driving route corresponding to the standard driving route data, and LMAX and LMIN represent respective routes corresponding to the upper and lower limits of the distribution of the driving route data used for calculating the standard driving route data. ing. The second threshold value is, for example, three times the standard deviation of the coordinate values of the driving route data, and is obtained for each position on the standard driving route at predetermined intervals. FIG. 8B is a histogram showing the distribution of all driving route data used for calculating the standard driving route data, focusing on a certain position. At this position, if the driving route data passing within the allowable range of the position on the standard driving route ± the second threshold is obtained, it is determined that the driving is normal, and the driving route data ( If the bottom of the driving route distribution (the black portion) is detected, it is determined that the driving route is abnormal.

Next, the operation data information creation unit 224 packetizes the standard speed data, the first threshold value, the standard route data, and the second threshold value created by the database creation unit 222 as described above, and Communication terminal 2
30 to the command center 300. Upon receiving this packet via the router 310, the command control unit 330 of the command center 300
Output to Upon acquiring the standard speed data and the standard route data from the received packet, the database management unit 320 registers them in the standard speed database and the standard route database of the storage unit 321 (step d1 in FIG. 4). In the above, the case where a new standard operation management database is created by several test runs has been described as an example, but not only during the test run, but also the operating speed and driving route obtained during normal operation are collected, and a large number of collections are performed. An operation management database may be created based on the data. Of course, the operation management database once created is not fixed but may be updated at any time based on position information and speed information obtained for each operation.

(2) Operation abnormality monitoring operation FIG. 9 is a flowchart showing the operation abnormality detection operation. First, at the first station on the route, the information processing device 220 mounted on the train 200 sends a request to download standard speed data, first threshold value, standard route data, and second threshold value corresponding to the route to be operated and operating conditions. PHS24
Send to the command center 300 by 0. If the corresponding standard speed data and standard route data have already been stored in the second storage unit 232 of the train 200, this download request is unnecessary. When receiving the download request from the train 200, the command control unit 330 of the command center 300 outputs this request to the database management unit 320. The database management unit 320 acquires the standard speed data, the first threshold value, the standard route data, and the second threshold value corresponding to the download request from the storage unit 321, packetizes the data, and sends the packet to the router 310. In this way,
The packet transmitted to the router 310 is transmitted to the train 200 via the mobile communication packet network N2, and the standard speed data, the first threshold, the standard route data, and the second threshold obtained from the packet are stored in the second storage unit. 232 (step S1).

When the download of the standard speed data and the like is completed, the train 200 departs from the first station on the route. Simultaneously with departure, the display panel 295 of the train 200 displays a standard operation speed graph (see FIG. 7B) and a standard operation route graph (see FIG. 8B) between the starting station and the arrival station (step). S2). Specifically, the operation abnormality detection unit 223 reads out the corresponding standard operation speed data and standard operation route data from the second storage unit 232, creates a standard operation speed graph and a standard operation route graph, and displays them on the display panel. 295.

When the operation of the train 200 is started, the operation abnormality detecting section 223 starts the operation speed abnormality detection and the operation route abnormality detection (step S3). Here, when no abnormality is found in the driving speed and the driving route (Step S4; NO), the driving abnormality detecting unit 223 returns to Step S3 and repeatedly executes the same processing. Then, when the train 200 arrives at the scheduled arrival station without detecting an operation abnormality, the train 200 reads the operation speed data and the operation route data from the first storage unit 231 and uploads them to the command center 300. On the other hand, when the operation abnormality detection unit 223 detects any abnormality in the operation speed or the operation route, the operation abnormality detection unit 223 outputs the detection result to the abnormality notification creation unit 225 as operation abnormality data.

For example, if a person invades the running route of the train 200 and the conductor who senses danger stops the train 200 suddenly, the driving speed falls outside the allowable error range of the standard driving speed data (FIG. 7 (b)). )), Whereby the operating speed abnormality detecting section 223b detects an abnormality in the operating speed. The abnormality notification information creation unit 224 creates abnormality notification information based on the operation abnormality data output from the operation abnormality detection unit 223, packetizes the abnormality notification information, and sends the packet to the command center 300 by the wireless packet communication terminal 230. (Step S5). Command control unit 330 of command center 300
Upon receiving the abnormality notification information, the PHS 350 calls the PHS 240 on the train 200 side. Then, the command control unit 330 of the command center 300
In order to ascertain the situation inside 0, an imaging command is generated, and the generated imaging command is transmitted from the PHS 350 to the train 200 (step S6). Command control unit 330
Creates a route map on which the train 200 in which the abnormality is detected from the received abnormality notification information and an operation graph of the train 200 in which the abnormality is detected are displayed on the display unit 340 (see FIG. 3). .

Upon receiving a command to start imaging from the command center 300, the imaging control unit 226 of the train 200 instructs the imaging unit 280 to start imaging. The imaging unit 280 receives this, performs imaging of the inside of the vehicle or the like, and outputs imaging data to the imaging control unit 226. Imaging control unit 226
Converts the imaging data supplied from the imaging unit 280 into a PHS2
The command is transmitted to the PHS 350 of the command center 300 by the command 40 (step S7). This imaging data is stored in the PHS350
And the display unit 3
40. Thereby, in addition to the above-described route map and operation graph, the in-vehicle image based on the image data is displayed on the display unit 340 (see FIG. 3).

The administrator who monitors the train operation at the command center 300 examines the countermeasures while referring to the image displayed on the display unit 340. The administrator can guess that the driving speed abnormality detected in the train 200 is caused by a sudden stop by referring to the operation graph and the like, but, for example, the inside of the vehicle such as a case where a large number of injured people have occurred. Until the situation, it is not possible to judge from the operation graph. Therefore, the administrator grasps the situation of the train 200 with reference to the in-car image. Here, for example, it is assumed that a large number of injured persons are displayed on the display unit 340. The manager of the command center 300 refers to the in-vehicle image displayed on the display unit 340 and recognizes that a large number of injured persons have occurred in the train 200, confirms the station where the train 200 will stop next, and Try to contact with. Then, the manager of the command center 300 explains the situation such as the occurrence of a large number of injured persons in the train 200 arriving soon to the station staff of the station, and requests a hospital arrangement or the like.
In response to this request, the station staff at the station arranges a hospital or the like and waits for the arrival of the train 200. Then, when the train 200 arrives at the station, the station staff at the station immediately brings the injured person into the station yard and takes it to the arranged hospital.

As described above, according to the train operation management system 100 according to the present embodiment, the G
Whether or not the driving speed and the driving route obtained from the PS 210 are normal can be determined based on the standard speed database and the standard route database obtained based on the driving information of a plurality of times. Therefore, it is possible to accurately determine whether the driving speed and the driving route obtained from the GPS 210 are normal. When an abnormal operation of the train 200 is detected, the train 200 automatically notifies the command center 200 that the abnormal operation has occurred. Therefore, it is not necessary for the crew of the train 200 to notify the occurrence of the driving abnormality by using a radio telephone or the like. In addition, the train 200
An imaging unit 280 that captures an image of the inside of the vehicle when an abnormality is detected is provided. Since the data captured by the imaging unit 280 is automatically transmitted to the command center 300, the manager of the command center 300 can easily grasp the situation inside the vehicle.

B. Modified Example <Modified Example 1> In the above-described embodiment, the case where the GPS 210 is mounted on the train 200 has been described as an example. However, the present invention is not limited to this, and may be applied to a route bus, for example. Can be. <Modification 2> Further, the train 200 may be provided with a plurality of imaging units 280 (for example, for each vehicle). When a plurality of imaging units 280 are provided in the train 200, each imaging unit 28
Although the in-vehicle images can be displayed on the display unit 340 of the command center 300 based on the image data supplied from 0, it is also possible to arbitrarily select which image unit 280 to operate in the command center 300. . Also,
In the command center 300, an imaging range or the like may be designated instead of simply instructing start / stop of imaging. The following is a description of a specific example.
For example, in a bus to which the train operation management system 100 is applied, a criminal who plans a bus jack (hereinafter, referred to as a bus jack criminal) travels to a bus driver on a route different from a normal driving route. Suppose you instruct When the driver travels on a route that deviates from the normal route as instructed by the bus jacker, the bus notifies the command center 300 that an abnormality has occurred in the driving route. When the abnormality of the driving route is detected, the imaging unit 280 starts imaging and sequentially supplies the imaging data to the command center 300. When the imaging data is received by the command center 300, the display section 340 of the command center 300 reflects the internal state of the bus. Here, when it is desired to display only the person who seems to be a bus jacker on the display unit 340, that is, when it is necessary to change the imaging range or the like of the imaging unit 280,
If the command center 300 can freely perform an operation of designating an imaging range or the like, it is possible to take an image of only the bus jack criminal without noticing the bus jack criminal, which is a foothold for an early solution. <Modification 3> In the present embodiment, a command indicating that imaging should be started is transmitted from the command center 300 to the train 200, and in response to this, the imaging unit 280 performs imaging and sequentially transmits image data to the command center. Although the configuration has been described in which transmission is performed to 300, the following configuration is also possible. For example, the operation abnormality detection unit 223 that has detected the operation abnormality sends a command to start imaging to the imaging control unit 226. Then, command center 300 notifies train 200 that image data should be transmitted. That is,
The imaging unit 280 is configured to immediately start imaging when an abnormal operation of the train 200 is detected without waiting for a notification from the command center 300. The imaging data captured between the start of the imaging and the reception of the notification from the command center 300 is stored in a storage unit (not shown), and the transmission of the imaging data is performed at the same time as the notification from the command center 300 is received. Start. As described above, the driving abnormality detection unit 223 may transmit a command to start imaging to the imaging control unit 226. If the imaging unit 280 does not wait for a notification from the command center 300 and immediately starts capturing an image when an operation abnormality of the train 200 is detected, the train 200 does not receive a notification from the command center 300. Alternatively, the imaging data output from the imaging unit 280 may be transmitted to the command center 300. Also,
The imaging unit 280 may be configured to image not only the inside of the vehicle but also the outside of the vehicle.
