Railroad crossing object detection systems and methods include radar sensors detecting object presence, speed and heading in a different manner. A controller compares signal outputs from the different sensors to provide traffic control preemption signals and self-diagnose sensor problems. The sensor devices may include an ultra-wideband (UWB) impulse radar device and at least one reflective device providing failsafe object presence detection and object non-presence detection in redundant fashion with at least a second sensor device such as a side-fired radar device.

A positioning and odometry system (POS) includes one or more sensors configured to collect sensor data. The one or more sensors are operably coupled to a portable housing configured to be coupled to a vehicle body. POS has processing circuitry operably coupled to the one or more sensors. The processing circuitry is configured to determine, in response to the collected sensor data from the one or more sensors, vehicle position and odometry data.

A system that includes a detection device, an imaging device, and a control device is disclosed. The detection device may generate proximity data relating to a proximity of an undercarriage of a rail vehicle, and the imaging device may capture one or more thermal images of the undercarriage. The control device may receive a first thermal image and a second thermal image of the undercarriage. The first thermal image may be captured using a first integration time, and the second thermal image may be captured using a second integration time. The control device may determine composite thermal data associated with the undercarriage. The composite thermal data may include information mapping a first range of thermal data and mapping a second range of thermal data to one or more components of the undercarriage. The control device may cause an action to be performed in connection with the composite thermal data.

A system is described for determining the location of a vehicle including an on-board computer and a ground penetrating radar mounted on the vehicle that is communicably connected to the on-board computer. A reflective landmark is located at a known location along the path of the vehicle. The reflective landmark includes reflective elements arranged to encode data. The ground penetrating radar transmits signal energy and detects reflected signal energy reflected by the reflective landmark and communicates encoded data representative of the reflected signal energy to the on-board computer. The on-board computer decodes the encoded data and thereby determines the location of the vehicle.

A warning system for detecting approaching object and method thereof are provided. A detection unit detects a moving path of the approaching object; a storage unit stores a warning information including the warning area and the confirmation condition; and a processing unit receives the detection signal provided by the detection unit to acquire the current moving path of the approaching object. When the approaching object is detected as moving in the buffering zone, the confirmation operation of the confirmation condition is activated. When the moving path falls in the warning area and fulfills the confirmation condition, the processing unit sends out a warning signal. Therefore, a potentially dangerous approaching object is accurately identified, and the warning is correctly sent.

A railroad car location, speed and heading sensor system including at least one self-powered, tie-mounted sensor node that is applicable universally to different railroad settings without using track circuits, inductive loops, radar systems, and wheel counters and associated disadvantages. Reliable and relatively low cost deterministic and redundant car presence detection is realized when multiple sensor nodes are arranged in a network, which may be a wireless mesh network, that is not affected by environmental conditions.

Railroad object detection systems and methods include radar sensors detecting object presence, speed and heading in a different manner. A controller compares signal outputs from the different sensors to make real time health assessments and self-diagnose sensor problems in a railroad application.
