SIGNALING OBJECTS CONTROL DEVICE Russian patent published in 2003 - IPC

FIELD: railway transport. SUBSTANCE: invention is designed for use in railway transport automatic control and telemechanic devices. Proposed device comprises complex relays, each consisting of two element relays. Second element relay is repeater of first element relay, and some contacts of first and second element relays are placed in correspondence circuit containing series-connected making contact of first element relay and making contact of second element relay, series-connected breaking contacts of said relays being connected in parallel to making contacts. Correspondence circuit is connected in series with similar correspondence circuits of element relays of other complex relays of signaling objects control device. Said correspondence circuit is connected in series with supply circuit of safety checking relays winding. Making contacts of said relay are placed in series with supply circuits in signaling control device influencing traffic safety and including other contacts of element relays. As a result, cost of manufacture is reduced owing to reduction of number of relays, and operation and maintenance expenses are decreased owing to dispensing with repair of signaling relays and replacement and transportation of said relays to place of repair. EFFECT: increased service life and reliability, reduced cost of manufacture and maintenance expenses of signaling objects. 1 dwg
