SYSTEM AND METHOD FOR CONTROLLING A LEVEL CROSSING OF A RAILWAY TRACK

A system controls a level crossing of a railway track installation. The railway track installation includes at least one track. The system includes at least two magnetometers associated with the at least one track and placed at corners of a crossing area between the at least one track and a road. The system also includes a level crossing control unit configured for receiving data from the magnetometers. Each magnetometer is arranged to detect a respective magnetic field vector of the earth's magnetic field and to send data representative of the magnetic field vector to the control unit. The control unit is configured to elaborate the data to detect changes in the magnetic field vectors due to the presence of a train in the crossing area and to control the level crossing as a function of the detected changes.

Roadway worker safety system and methods of warning

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.

Smart cam for digitalization of a gate mechanism
11938985 · 2024-03-26 · ·

A highway grade crossing gate mechanism having a smart cam system capable of measuring a parameter of the gate mechanism in real time is provided. The gate mechanism includes a DC motor, a cam system, and a controller. The DC motor is coupled to a main shaft for driving a gate arm between a vertical position and a vertical position. The cam system includes manually adjustable cams coupled to the main shaft that move contacts to open or close at some preset angular rotation in order to set operational features of a crossing gate. An internal sensing device is disposed internal to the cam system measuring a parameter of the gate mechanism in real time. A controller controls the motor and receives and stores the parameter. The parameter may be transmitted to an external network giving accurate feedback of the state of the gate mechanism in real time.

MANAGEMENT SYSTEM AND CONTROL SYSTEM

A management system according to the present disclosure is a management system that manages a travel plan of a vehicle that is capable of traveling on a road and a railway track, and includes controller that creates the travel plan of the vehicle. In a case where there is a route candidate track that is a railway track that is possibly used as a travel route of the vehicle, the controller acquires a railway operation schedule for the route candidate track, and determines whether the route candidate track can be used as the travel route of the vehicle, based on the operation schedule. In the case where the route candidate track can be used as the travel route of the vehicle, the controller creates a travel plan according to which the vehicle travels along the travel route including the route candidate track.
