Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signal recording / reproducing apparatus, and more particularly, to a signal recording / reproducing apparatus for recording / reproducing a train operation status.

[0002]

2. Description of the Related Art Conventionally, train operation crews carry out operation management of a train by carrying a card or the like in which a train-specific operation time specified by an operation management center is carried. Further, in operating all trains, it is necessary to grasp the state of facilities, the operating state of each train, and the like. Operation information of various onboard devices
It is disclosed that the operation status of each train is displayed on an operation display panel by using a train radio device to be taken into a central control device of an operation management center.

[0003] In addition, GPS (Global Positioning System)
A navigator device that receives position information from m), reads out map information stored in a CD-ROM, and displays the current position is mounted on a moving body such as a car or a ship.

[0004]

When operating a train, a train crew needs not only operation time information but also information indicating conditions in the track area, such as construction work and dangerous spots. In addition, since such information changes every day, it is necessary to always provide the driver with the latest information for safe operation.
It is desirable that such information be notified to the driving crew at a necessary timing.

[0005] In addition, information on trains requiring operation records requires not only the status of the equipment mounted on the train, but also video information and the like that can be used to objectively understand the status in the event of an accident. However, while the train is running, a long recording medium is required to record all video information. Therefore, it is necessary to compress the video information or to set a section to be recorded in the operation section, and to reduce the amount of information to be recorded by, for example, setting the position of a station yard or a railroad crossing where an accident is likely to occur.

There is a means for exchanging information between the operation management center and each train by using train radio for information transmission.
Since the train radio uses a specific wavelength shared by all trains, there is a problem that large-capacity information transmission such as video information cannot be performed. Therefore, in order to transfer information between the operation management center and each train, a small-sized storage medium that can be carried by a driver is desirable.

An object of the present invention is to use a portable storage medium to provide the latest various operation control information to a driver crew in a timely manner to assist the operation, and to provide instruction information at the time of operation.
It is an object of the present invention to provide an information recording / reproducing apparatus capable of easily managing train-specific operation information by recording operation record information such as video information and on-board equipment information on the same storage medium.

[0008]

In order to achieve the above-mentioned object, the present invention provides a means for detecting a current position, a means for inputting operation control information, and an operation control information from a recording medium based on the current position information. And means for reading and displaying status signal information of various in-vehicle devices mounted on the train and video information input from a camera attached to the front of the vehicle in the same storage medium. Then, an optical disk was used as a storage medium.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory diagram of the present invention, in which operation control information unique to a train is recorded on a recording medium 5 using an optical disk.
The operation management center 1 performs recording / reproduction on a vehicle, and a train 6 mounted on an optical disk recording medium 5 for operation.

First, the flow of main signals will be described with reference to FIGS. Before operation, the operation management center 1 writes operation control information unique to the train on the optical disk recording medium 5 (steps 301 and 302). The operation crew receives the optical disk recording medium 5 from the operation management center 1, carries it, and gets on the train (step 303). Then, the optical disk recording medium 5 is set in the control device 10 in the train and the operation starts (step 304). Before starting the operation, the control unit 25 of the control device 10 checks whether the unique train information recorded in the train information storage unit 29 and the train information of the scheduled operation recorded on the optical disc recording medium 5 are the same. I do. If they are the same, control is started as train operation information (step 305). When the operation starts, the current position information is input from GPS or a train distance measuring means using an odometer (step 306). When the position information matches the position information set in the operation control information, the display information is read from the optical disk recording medium 5 and displayed on the display unit (steps 308 and 309). Similarly, when the information coincides with the recording start information of the video information, the video information from the camera mounted on the front of the vehicle body is compressed and recorded on the same optical disk recording medium 5 (steps 310 and 311).

When the operation is completed, the optical disk storage medium 5 is removed from the train control device 10 (step 313), and is taken to the operation management center 1 to register the operation record information (steps 314, 315, 316).

Next, the detailed operation of the control device 20 will be described with reference to FIG. The operation crew sets the optical disk storage medium 5 on which the operation control information is recorded in the optical disk drive 28. The train information storage unit 29 stores information unique to the train such as a train number. The train codes in the operation information recorded on the optical disk storage medium 5 are compared. The control unit 25 is a part for instructing the operation of the entire apparatus. The current position information can be obtained from the GPS antenna 7, the GPS input unit 21, and the distance detection unit 24. When the current position information matches the operation control information recorded on the optical disk storage medium 5, the control information is read from the optical disk storage medium 5. , Playback unit 26
And output it to the monitor and speaker to notify the crew.
Operation information and vehicle information are also recorded on the optical disk together with position information. Similarly, video information taken from a camera 8 attached to the front of the vehicle is recorded on the optical disk storage medium 5.

FIG. 4 shows a format of operation control information, which is composed of train-specific train information, operation time information, display control information, record control information, operation record information, and the like.

[0014]

According to the present invention, large-capacity information can be easily exchanged between the operation management center and the operating crew by storing the information necessary for the operation on one optical disk storage medium.

Further, the latest crew information can be provided to the crew in a timely manner, so that the crew can be assisted in the operation and the required storage information amount can be saved by setting the recording section of the video information.
