Embodiment Construction
[0018] Referring initially to Figure 1, a railway locomotive signaling system 100 is known in the art. Figure 1 shows the implementation of such a railway locomotive signaling system. A rail vehicle 106 , such as a locomotive, has wheels 108 that travel on rails 102 and 104 . The wheels 108 are connected by an axle 120 . As discussed below, locomotive signal parameters 126 identify one or more operating parameters of a train on a railroad track. The locomotive signal parameters 126 are encoded into the locomotive status signal 118 and transmitted by the locomotive signal transmitter 110 across the rails 102 and 104 . As shown in FIG. 1 , the transmitted locomotive status signal 118 is transmitted within the rail 102 . In the event that there is no railcar 106 on the track within the intended locomotive signal track circuit 128 or segment, the locomotive status signal 118 is sent from rail 102 to rail 104 via the resistive rail switch 116 to complete the locomotive signal tr...

A system and method for railway vehicle signal quality detection and reporting used in conjunction with a railway vehicle signaling system (100), wherein a status signal (118) is communicated on a railway track (102 or 104). The status signal (118) has a locomotive signal parameter (126) indicative of the status of the track area. A signal detector (112 or 114) detects a status signal (118) sent via the railway track (102 or 104). A signal measurement subsystem (310) associated with the signal detector (112 or 114) measures a locomotive signal parameter (126). The quality analysis subsystem (312) analyzes the measured locomotive signal parameters (202) and determines a measure of the quality of the locomotive signal parameters (126). The system may include equipment mounted on a rail vehicle (106), such as a locomotive, or mounted along a section of track or mounted on a mobile device. The system may also include locomotive signal quality collection and reporting equipment (400). The method includes detecting a locomotive status signal (118), and measuring a locomotive signal parameter (126) based on the detected status signal. A measure of the quality of the measured locomotive signal parameters (126) is determined and reported.
Description
technical field [0001] The present invention relates generally to railway signaling systems and methods. More particularly, it relates to systems and methods for detecting and reporting malfunctioning of locomotive signaling track circuits. Background technique [0002] Railway signaling has traditionally been based on the concept of protecting track areas, sometimes referred to as "blocks", by means of some form of signaling system that conveys information about the status of preceding track sections to locomotive engineers. Typically, wayside signals are located along the track and are controlled by electronic logic circuitry in response to the presence of rail vehicles and the state of the road segment associated with a given wayside signal. In such systems, each wayside signal typically displays a type of light, called the "aspect" of the signal, that can be seen by the engineer in the locomotive and indicates the status at that location. [0003] A more advanced signa...
