  • The application of technology of the modern electronic presents overall economic advantages for the system. The starting of a system which eliminates the security relays (excepting the associate to the track circuits), in which a big part of the wired is replaced for multiplexus transmission of facts, and which need smaller constructions, less maintenance and less resources for the planification and installation.

    One of the biggest problems to resolve to apply these concepts to the railway field is guarantee the availability and the functioning exempt of mistakes of a system whose components aren’t intrinsically secure. This has took to study in detail, for one side the equipment to use and for another side the programming techniques. This aspect constitutes the main object of this communication, which first presents the disposition of an enclavation system with micro-processing units and after describes the basic beginning of design of the operation logical.

    The technique of the “constructed programming” is introduced briefly, it is very advantageous and amply used for BR for the development of informative systems in the security field and, finally, the validation methods of adequate program are exposed.

    The works realized permit secure that the experience obtained endorse the reliance of the security system based in micro-processing units.
