Next, the process of estimating the operating state of the train (operating state estimation process) will be described.

FIG. 4 is a diagram showing an example of a flowchart related to the operation state estimation process executed by the operation state estimation unit 201. The operation state estimation process is executed (regularly) at predetermined time intervals.

In step S401, the operation state estimation unit 201 performs special such as travel route information (for example, train number, timetable information, train type, current station, next stop station, formation division / combined operation, etc.) from the input train operation information. (Operation implementation station, etc.) is acquired and used as one of the estimation factors of the operation status of the train.

In step S402, the operation state estimation unit 201 calculates the mileage of the train based on the speed information of the train obtained from the input speed generator or the like 124 (speed generator, connected equipment, etc.), and self-calculates. It identifies the position of the train and the running state of the train, and is used as one of the estimation factors of the operating state of the train.

In step S403, the operation state estimation unit 201 acquires the input operation information of the crew (for example, the operation information of the master controller 120, the operation information of the various switches 126, the operation information of the various operation cocks 127), and operates the train. It is used as one of the estimation elements of the state.

In step S404, the operation state estimation unit 201 receives input train operation information (for example, operation information of various vehicle circuits (operation information of door 121, pantograph 129, etc.), operation information of various devices 122, failure information, etc.). Is acquired and used as one of the estimation factors of the operating state of the train.

In step S405, the operation state estimation unit 201 estimates the operation state of the own train based on the information acquired in the above steps S401 to S404, and notifies the camera image data amount determination unit 202 of the estimated result. For example, the operation state estimation unit 201 uses the camera selection table 300 to acquire the operation state of the train defined according to the acquired operation information, operation information, and operation information.

As a result, a series of processes in the operation state estimation unit 201 is completed.

Next, a process (data amount determination process) in which the camera image data amount determination unit 202 determines the data amount of the image to be displayed on the driver's cab display 112 based on the operating state of the train will be described. The data amount determination process is started, for example, when the operation state estimation unit 201 notifies the camera image data amount determination unit 202 of the estimation result of the train operation state.

FIG. 5 is a diagram showing an example of a flowchart relating to the data amount determination process executed by the camera image data amount determination unit 202.

Here, the vehicle information control device 111 includes a parameter 500 used in the data amount determination process. The parameter 500 is stored in, for example, the storage unit 114. The parameter 500 includes, for example, a data band X [bit / sec] allocated for image communication (image distribution), a main image distribution cycle a [sec], a sub image distribution cycle b [sec], and a main image. The data amount A [bit] and the data amount B [bit] of the sub image are included.

The data band X may be the band of the network connecting the vehicle information control device 111 of the leading vehicle and the vehicle information control device 111 of the intermediate vehicle, or may be the band of the network in the leading vehicle. Of the bands of both networks, the smaller band may be used, or the other band may be used. Further, the data band X may be a fixed value or a value that dynamically fluctuates according to the data band allocated for control information distribution. The distribution cycle a of the main image and the distribution cycle b of the sub image may have the same value or different values. The data amount A of the main image and the data amount B of the sub image may have the same value or different values.

In step S501, the camera image data amount determination unit 202 acquires the estimation result of the operation state of the train notified from the operation state estimation unit 201.

In step S502, the camera image data amount determination unit 202 determines display candidates (main image and sub-image) corresponding to the estimation result of the operating state of the train acquired in step S501. For example, the camera image data amount determination unit 202 uses the camera selection table 300 to deliver a target camera for delivering an image to be displayed on the main image and a target camera for delivering an image to be displayed on the sub image (for example, the camera to deliver the image to be displayed on the sub image. For example, the camera number) and the number n of sub-images to be displayed are determined. The target cameras are uniquely assigned to a plurality of cameras arranged at each location of the vehicle shown in FIG.

In step S503, the camera image data amount determination unit 202 calculates the data band P (= A ÷ a) of the main image using the result determined in step S502 and the parameter 500.

In step S504, the camera image data amount determination unit 202 compares the data band P of the main image calculated in step S503 with the data band X allocated for image distribution. When the camera image data amount determination unit 202 determines that X is P or less, the process is transferred to step S505, and when it is determined that X is larger than P, the process is transferred to step S507.

In step S505, the camera image data amount determination unit 202 calculates the data amount A'(= X × a) of the main image because the data band information P of the main image is equal to or larger than the data band X allocated for image distribution. ..

In step S506, the camera image data amount determination unit 202 calculates the data amount of the sub image as “0 (zero)”.

In step S507, the camera image data amount determination unit 202 calculates the data amount of the main image as A because the data band P of the main image is less than the data band X allocated for image distribution.

In step S508, the camera image data amount determination unit 202 calculates the data amount B'(= (XP) × b ÷ n) of the sub image.

In step S509, the camera image data amount determination unit 202 compares the data amount of the sub image calculated in step S508 with the data amount B of the sub image. When the camera image data amount determination unit 202 determines that B is B'or less, the process is transferred to step S510, and when B is determined to be larger than B', the process is transferred to step S511.

In step S510, the camera image data amount determination unit 202 calculates the data amount of the sub image as B because the calculated data amount B'of the sub image is equal to or larger than the data amount B of the sub image.

In step S511, the camera image data amount determination unit 202 calculates the data amount of the sub image as B'because the calculated data amount B'of the sub image is less than the data amount B of the sub image.

For example, when the cameras provided in the train include cameras with different specifications (for example, a camera that captures a high-quality image, a camera that captures a low-quality image), as described above, depending on the operating state of the train. It is preferable to calculate the amount of data.

As a result, a series of processes in the camera image data amount determination unit 202 is completed.

In the data amount determination process, a method of calculating the data amount according to the operating state of the train has been described, but the method is not limited to this. For example, the amount of data may be determined by reading the information stored in the storage unit 114 according to the operating state of the train. For example, the main image camera information 305 in the camera selection table 300 defines the camera identification information and the amount of data, and the sub-image camera information 306 defines the camera identification information and the amount of data, and the camera is selected. The amount of data may be determined using the table 300.

Next, a process of notifying the selected camera of the amount of image data (data amount notification process) will be described. The data amount notification process is started, for example, when the camera image data amount determination unit 202 notifies the camera image data amount notification unit 203 of the data amount of the main image or the like.

FIG. 6 is a diagram showing an example of a flowchart relating to the data amount notification process executed by the camera image data amount notification unit 203.

In step S601, the camera image data amount notification unit 203 includes the camera numbers of the main images and sub-images to be displayed and the data amount of each image notified from the camera image data amount determination unit 202, and the distribution cycle a of each image. b and is acquired.

In step S602, the camera image data amount notification unit 203 notifies the camera of the camera number to be displayed of the main image of the data amount of the main image in the distribution cycle a of the main image.

In step S603, the camera image data amount notification unit 203 notifies the camera of the camera number to be displayed of the sub image of the data amount of the sub image in the distribution cycle b of the sub image.

As a result, a series of processes in the camera image data amount notification unit 203 is completed.

Next, the process of transmitting the image display data to the driver's cab display 112 (display data transmission process) will be described. In the display data transmission process, the camera image display data transmission unit 204 receives the image data transmitted from the camera. It will be started when you do it.

FIG. 7 is a diagram showing an example of a flowchart relating to the display data transmission process executed by the camera image display data transmission unit 204.

In step S701, the camera image display data transmission unit 204 receives an image (image data) from each camera of the vehicle. Further, in step S701, the camera image display data transmission unit 204 receives the main image display command notified from the camera image data amount determination unit 202 and the camera number of the display target of the main image and the sub image.

In step S702, the camera image display data transmission unit 204 transmits the image data received from the camera to which the main image is displayed to the driver's cab display 112 as display data together with the main image display command.

In step S703, the camera image display data transmission unit 204 transmits the image data received from the camera to which the sub image is displayed to the driver's cab display 112 as display data together with the sub image display command.

As a result, a series of processes in the camera image display data transmission unit 204 is completed.

Next, the screen display of the image of the camera that supports the operation of the train (operation support camera image) on the cab display 112 will be described.

FIG. 8 is a diagram showing an example of screen display of the operation support camera image (operation support camera image display screen 800).

For example, a vehicle information control system (vehicle information control system 100) including a vehicle information control device (for example, vehicle information control device 111) that controls information related to a train vehicle, and operation information related to the operation of the train (for example). For example, the operation information 302), the operation information related to the operation of the equipment of the train (for example, the operation information 303), and the operation information related to the operation of the train (for example, the operation information 304) are input, and the operation information is described. A plurality of cameras (for example, cameras 130 to 139) connected to the train according to the operation state of the train (for example, the operation state 301 of the train) provided according to the operation information and the operation information. By selecting a camera for an image to be displayed on a display device (for example, a driver's cab display 112) connected to the vehicle information control device, the amount of data related to communication of the vehicle information control device can be controlled (for example). For example, it is characterized by including a control unit (for example, a control unit 200) that controls the camera to give permission to transmit image data and controls to acquire the image data stored in each vehicle information control device 111. And.

According to the above-described configuration, for example, by selecting a camera according to the operating state of the train and suppressing the communication of image data that does not need to be displayed, a large amount of unnecessary image data flows through the communication network. It will be possible to avoid the situation where the image that the crew wants to check is missing.

Further, for example, on the screen displayed on the display device (for example, the operation support camera image display screen 800), the first display area (for example, the main image display area 801) mainly used in the operation state of the train is displayed. A second display area (for example, a sub-image display area 802) used as a slave is provided, and is defined according to the operation information, the operation information, and the operation information, and the first display area or the first display area or The second display area is associated with the specific information (for example, the camera selection table 300) that can identify the image to be displayed on the display device, and the control unit has the specific information based on the specific information. The amount of data of the image displayed in the first display area has priority over the amount of data of the image displayed in the second display area (for example, in the main image so as to be contained in the data band allocated for image communication). By determining the amount of data to be used and then determining the amount of data to be used for the sub-image), the amount of data of the image communicated by the vehicle information control device is kept in the data band allocated for image communication (the amount of data to be used is determined). (See steps S503 to S511).

According to the above-described configuration, for example, by prioritizing the images according to the operating state of the train, it is possible to avoid a situation in which the main image having a high priority is missing as much as possible.
