FIELD: transport.SUBSTANCE: system represents open system of interacting by means of internal CAN interface locomotive indicating unit and central computer unit to which following devices are connected: satellite navigation system antenna, receiving coils for ALSN and ALS-"??" signals, electropneumatic valve, path and speed transducer, SSPSTRS controls, brake cylinder and brake line pressure transducers and power supply. Central computer unit contains central computer cell, safe comparison cell and input board. To locomotive indicating unit following devices are connected: recording cassette via recording unit, driver vigilance lever and input unit. Additionally, following devices are introduced into central computer unit: satellite navigation cell, ALS signals and filter board for filters which connected via internal CAN interface are connected to central computer cell which is connected in series over two-channel input/output via safe comparison cell, and its constituent amplifier with electropneumatic valve. Central computer cell implements performance monitoring for all cells, the satellite navigation cell is made capable to receive signals from satellite navigation system antenna, from brake cylinder and brake line pressure transducers, and via input board is connected with path and speed transducers and SSPSTRS digital signals. ALSN and ALS-"??" signals from rail circuit via receiving coils come to ALS receiving coil where they are decoded. The filter board provides filtration of input signal coming from indicating unit and protects electrical feed circuit of central computer against overloading. The system determines its position as per data from satellite navigation system and electronic map.EFFECT: higher traffic safety.5 cl, 2 dwg |
