THREE-CHANNEL DEVICE FOR CONTROLLING FINAL-RELAY UNITS Russian patent published in 2007 - IPC H03K19/23 B61L19/14 

FIELD: railway automatic control and teleautomatics, centralized power control systems including control computer systems for microprocessor centralizing switches and signals for small, medium, and large railway stations.

SUBSTANCE: novelty is that proposed device characterized in greater quantity of parameters being diagnosed and in introduction of means for on-line variation of controlled-entity modes of operation that has pulse signal supplies (PSS) 1, power supplies, final-relay unit (FRU) 5, control-signal supply units (CSSU) 3, output switches (OS) 4, output-switch monitoring units (OSMU) 6 is provided with newly introduced three data acquisition modules (DAM) 15, three processor units PU 12, and three memory units (MU) 13. Power supply of each of three channels is made in the form of safety monitoring and disconnection module (SMDM) 2 designed for generation, monitoring, and on-line disconnection of supply voltages from output stages of OS 4 and PSS 1. PSS 1 unit, OS 4, OSMU 6, and their interconnections are integrated into output amplifier module (OAM) 16 designed to supply control signals for final relays through OS unit 4 and SMDM 2 control signals through PSS 1. CSSU 3 unit, PU 12 unit, MU 13, and their interconnections are integrated into controller module (CM) 14 designed to control OS 4 unit, PSS 1, as well as to check final relays, floor-mounted equipment, and output switches for condition; OAM 16 inputs designed to supply with power output stages of PSS 1 and OS 4 units in each of device channels are connected to respective outputs of same-channel SMDM 2, two other inputs of OAM 16 designed to control PSS 1 and OS 4 units are connected to respective outputs of same-channel CM 14, output designed to check OAM 16 output switches for condition is connected to one of inputs of same-channel CM 14 and first of OAM 16 outputs designed to control SMDM 2 is connected to first of same-channel SMDM 2 inputs. Second and third outputs of first-channel OAM 16 designed to control SNDM 2 are connected to second and third inputs of SMDM 2 of third and second channels, respectively; second-channel OAM 16 is connected to second and third inputs of first- and third-channel SMDM 2, respectively; third-channel OAM is connected to second and third inputs of second- and third-channel SMDM 2, respectively. Same outputs of OAM 16 output switches of three channels are interconnected and connected to FRU 5; same inputs of DAM 15 of three channels designed to receive feedback signals informing about condition of final relays and floor-mounted equipment are likewise interconnected; output of each DAM 15 is connected to second and first input/output of CM 14 of third and second channels, respectively; second input/output of second-channel CM 14 is coupled with first input/output of third-channel MC 14. Trigger inputs of all SMDM 2 are interconnected.

EFFECT: enhanced safety of traffic, enlarged functional capabilities.
