FIELD: railway transport; signaling and communication; traffic control. ^ SUBSTANCE: proposed system containers two processor sets operating synchronously according to similar program, built-in hardware circuit to which indicated processor sets are connected and which is designed to compare operation of processor sets and to act onto operation of system if one of sets fails. System is essentially monoblock of multimodule structure including module of central processor consisting of said two processor sets, at least one interface data acquisition module concerning condition of objects of railway station and adjoining block sections, interface modules forming control signals acting onto actuating signaling devices and interface modules to transmit important orders. All modules are intercoupled by system bus consisting of two identical buses, each being connected to corresponding processor set. Invention is aimed at enlarging functional capabilities of system i.e. developing failure-free system to control large number of objects at stations and track block section with possibility of control, improving stability of operation owing to use of transition into protected disconnection state or protected failure in modules designed for implementing important orders. ^ EFFECT: enlarged operating capability of system. ^ 7 cl, 2 dwg |
