FIELD: physics; communication. ^ SUBSTANCE: invention concerns to safety precautions means for railway transportation and can be used for provision of a passenger train with the wireless address signal system and interior communication. The key of repeater activation contains microprocessor, two diodes, condenser, resistors. The condenser which is carrying out a filtration of the feeding voltage is connected to an inlet of a food of the microprocessor. The diodes are connected parallel to the information and synchronising inlet/exit of the microprocessor with possibility of realisation of their protection against overstraining. Resistors are connected to not used inlets of the microprocessor. The microprocessor exit is executed with connection possibility to a repeater and got through a current circuit from an optron and one of resistors on a voltage of a food with maintenance of a galvanic outcome of an exit and a repeater. ^ EFFECT: provision of a passenger train with the wireless address signal system and interior communication. ^ 1 dwg |
