Method for the safe single-channel transmission of data between the computer junctions of a computer network as well as multi-computer system and computer junctions

摘要

A method for safe single-channel transmission of data between the computer junctions (rk1, rk2) of a computer network (Rv), in particular for use in iron path signal installations in thea) a manner which is safe in terms of the form of a computer junctions (rk1), of the at least two parallel working, by means of a node internal communication channel, connected with each other with computer (r1a and r1b, r1c) by means of a node external communication channel (kan) to another such a computer junctions (rk2) useful data and from the user data determined and this in the case of the transmission of redundant data, which sends,characterized by the,b) that the detection of correct redundant data payload data, which a computer (r1a) transmits via the node external communication channel, exclusively in a different computer (r1b, r1c), or by sequential calculation, wherein the redundant data in a computer (r1a) exclusively of a in the other computer (r1b, r1c) determined partial result, be determined in the case of thec) the redundant data from the useful data are determined with the aid of a table, which in each computer in a data memory with fixed addresses..
