The present invention provides a system for preventing an accident that minimizes the number of monitor devices and prevents a collision accident to reduce the work and cost burdens. The system for preventing an accident 1 of the present invention includes an imaging device 10, a monitor server 20, and a warning device 60. The control unit 30 of the monitor server 20 executes the area receiving module 31 to receive input of an approach area as an area where a vehicle approaches and a danger area where is danger from an approaching vehicle based on a base image taken by the imaging device 10. The control unit 30 executes the first judgment module 33 to judge whether or not a vehicle enters the approach area based on an image taken by the imaging device 10. If a vehicle enters the approach area, the control unit 30 executes the second judgment module 34 to judge whether or not a person, etc., enters the approach area or the danger area. If a person, etc., enters the approach area or the danger area, the control unit 30 executes the warning module 35 to instruct the warning device 60 to provide warning information.

A railway collision protection and safety system has a vehicle device located on rail vehicles at a work zone, a personal protection unit located with rail workers at the work zone, and a dispatcher processor at a control center. An authority limit within the work zone may be determined by the dispatcher processor, and an authority exceeded signal is sent to the rail vehicle when the rail vehicle is determined to exceed the authority limit.

A rail warning system using wireless portable transmitters/receivers. The rail warning system uses chirp spread spectrum modulation scheme, and alerts personnel in work zones on or near train tracks as well as optionally, on track equipment and train operators , of approaching trains or on track equipment. Portable wayside devices may also be positioned on the rail web, optionally magnetically, to alert work personnel, allowing for secure placement but also portability to other locations on the same track or adjacent tracks.

A locomotive control method includes wirelessly communicating from at least one wireless transmitter positioned proximate a railroad crossing to a wireless locomotive receiver of a locomotive, either directly or indirectly via a wireless wayside transceiver, an indication if the railroad crossing is clear for passage of the locomotive through the railroad crossing, and receiving by the locomotive receiver the indication wirelessly communicated by the at least one portable transmitter. A locomotive controller or an operator of the locomotive can determine, based on the indication received by the locomotive receiver from the at least one portable transmitter, if it is safe for the locomotive to travel through the railroad crossing. The locomotive 4 can then be operated based on the determination.

A locomotive control system includes one or more processors configured to determine quality of service (QoS) parameters of locomotive devices communicating data with each other in an Ethernet network that is configured as a time sensitive network (TSN) and that is onboard a locomotive. The one or more processors also are configured to determine available communication pathways in the TSN through which the locomotive devices are able to communicate the data. The one or more processors also are configured to select one or more of the available communication pathways and to designate communication times at which the data is communicated between the locomotive devices to satisfy the QoS parameters of the locomotive devices.

A system and method for inspecting a railway track using sensors oriented at an oblique angle relative to a rail vehicle on which the system is traveling. The orientation of the sensors allows for different data to be gathered regarding a particular rail including rail design specifications (gathered based on manufacturer markings detected and analyzed by the system), rail seat abrasion values based on direct measurement of rails from the oblique angle, and other analysis of rail features including joint bars, rail welds, bond wires, rail holes, and broken rails. The use of an air blower, ducts, and one or more air distribution lids over the sensors helps remove debris from blocking the sensors and structured light generators.
