[0003]
That is, in a railway station yard, tracks are complicatedly gathered, and at a branching point, a route such as a switch, a traffic light, a sign, or the like is opened, or whether or not the route is allowed to enter is displayed. A large number of devices are provided, and they are switched according to the arrival, departure, passage, etc. of trains and maintenance vehicles, etc., and the routes required by trains and the like are opened. The switching operation must be performed promptly and appropriately in response to the arrival, departure, passage, etc. of the train, and the train or the like must be efficiently operated or passed.
[0004]
In the electronic interlocking system, the route is set by using a start lever / landing push button or a dedicated keyboard, and the route competition of a train or the like and the locking of a switch are performed by a software program. Each target area has its own layout and equipment, and when the equipment has been modified or updated, there is a change, so that specific interlocking data for the target area is created and the equipment at each location operates correctly. It is necessary to set as follows.
[0005]
Conventionally, when creating and deploying these interlocking data, it reads from the interlocking chart written on paper the wiring schematic information that reflects the station-specific line wiring shape and the interlocking table information that reflects the interlocking conditions. The read information is input to an interlocking data creating apparatus to create interlocking data, which is written into a ROM by a ROM writer, and inserted into a predetermined print board of the apparatus, or a flash ROM previously mounted on a printed circuit board. Linked data is implemented in the device using a method of writing data online via a device. After creating the linked data, the linked chart itself, which was written on paper, was stored and managed separately from the linked data. (For example, see Patent Document 1).
