A method of detecting signal light integrity and viewability of a plurality of signal lights is performed by a signal light monitoring system including a plurality of signal light monitors coupled to the signal lights and a network interface communicator configured to interface the signal light monitors to a wireless network. The method includes receiving detection data from each signal light monitor, measuring a first measurement of signal light integrity, processing the first measurement of signal light integrity to determine at least one signal light integrity value, retrieving at least one performance requirement associated with the signal light monitors, comparing the performance requirement to the signal integrity value, determining whether each signal light monitor is compliant with the performance requirement, and propagating the compliance determination and the first measurement of signal light integrity over the wireless network via the network interface communicator.

Method for ensuring signal light integrity and viewability

A system and method is proposed to ensure detection of signal light integrity and viewability. The system includes a wireless network of signal light monitors attached unobtrusively to the sun visors on each signal light for which monitoring is required. Each signal light monitor includes diverse sensors which detect signal light integrity and viewability. The detection sensors are simultaneously active to detect signal light intensity, color intensity and viewability. The information obtained from the sensors is transmitted wirelessly to a base signal light monitor. The base signal light monitor communicates this information over a mesh network to an edge processor. The network is self-healing and ensures data integrity using a pre-calculated communication link if a communication link between base signal light monitors is lost or broken. The edge processor is capable of image and condition analysis on the detection data and communicates events to an enterprise network for action.

System and method to ensure signal light integrity and viewability

Systems and methods are disclosed for reliable detection of oncoming trains and for warning roadway personnel working on the railroad track of the oncoming train. A train detection system includes a wireless communication network further including train detection modules attached to catenary poles along the sides of the railroad track. Each train detection module is equipped with at least two diverse sensors configured to detect trains and other on-track vehicles. Each train detection sensor is simultaneously active and works with other train detection sensors to detect an approaching train and generate train alerts. The train alerts are transmitted wirelessly over the wireless communication network by the train detection modules. The system transmits train alerts to personal alert devices worn by roadway workers. The personal alert device forms an ad-hoc wireless network with the train detection modules.

Roadway worker safety system and methods of warning

A system for reliable detection of an approaching train and warning the roadway workers in proximity of the track is described. The system comprises at least one train detector cone (TDC) deployed along a side of an active railroad track and one or more personnel warning cones (PWC) placed near the work site, the cones configured in a wireless mesh network to provide redundant communication links. Detection of a train by the train detector cone is transmitted to the personnel warning cones which provide audible and visual warnings to nearby roadway workers. The system also includes a remote server for centralized tracking and monitoring of the train detector cones and personnel warning cones.
