摘要： A sequential monitoring system is for an interlocking logic system and a track circuit system including a plurality of track circuits. The sequential monitoring system includes an interface between the interlocking logic system and the track circuit system; and a processor structured to monitor a state of each of the track circuits, validate a sequence of state changes of the track circuits, and interrupt and correct invalid track circuit state indications between the track circuit system and the interlocking logic system. The interface normally passes inputs from the track circuit system to outputs to the interlocking logic system. When an out of sequence event occurs, the processor applies a quarantine to a minimum of three of the track circuits in a quarantined area, thereby inhibiting use of an unoccupied track circuit in the quarantined area.

The system includes a mounting structure structured to be coupled to a housing of the switch machine and a first sensing device coupled to the mounting structure. The first sensing device is positioned and structured to detect movement of the point detector bar a second predetermined distance from the initial position, wherein the second predetermined distance is less than the first predetermined distance.

摘要： A railroad monitoring apparatus includes first and second diverse vital processing units, first and second current sensors configured to measure the current being provided to one or more signaling elements of an item of wayside signaling equipment, and means for measuring voltage levels being supplied to each of the signaling elements. The first processing unit receives a first current measurement from the first current sensor and the measured voltage levels, and the second vital processing unit receives a second current measurement from the second current sensor and the measured voltage levels. The vital processing units are each programmed to determine based on one or more of the first current measurement, the second current measurement and the measured voltage levels: (i) the state of the item of railroad wayside signaling equipment, (ii) failures within the item of railroad wayside signaling equipment, and (iii) failures within the monitoring apparatus itself.
