Title:
COURSE COMPETITION JUDGING METHOD IN ELECTRONIC INTERLOCKING DEVICE
Document Type and Number:
Japanese Patent JP3401045
Kind Code:
B2
Abstract:
PURPOSE: To judge course competition by using a course locking data required as a link processing and saving a memory area while utilizing such a merit as a fast processing time by a matrix method in the electronic interlocking device of a railway.
CONSTITUTION: A course locking matrix 1 made by using a computer based on the course locking data in an interlocking chart is collated with a definite table 2 under setting for memorizing the course locking data in an already set course. During this collation, both course locking data in the course locking matrix 1 and the definite table 2 under setting are calculated by AND calculation and the course competition is judged to be present when this calculation result is not all zero, while when the result is all zero, both course locking data in the course locking matrix 1 and the definite table 2 under setting 2 are further calculated by OR calculation and a course setting receipt is judged to be present.
