A signal detection system for use with a signaling system is disclosed, the signal detection system comprising a plurality of electrical terminals including a source terminal and an output terminal, the output terminal being connected to a signaling device. An auxiliary terminal electrically coupled to at least one of the plurality of electrical terminals is provided. A current sensor is coupled to the auxiliary terminal for detecting an electrical signal for controlling the signaling device. The current sensor generating an output signal in response to the detection of the electrical signal for controlling the signaling device for monitoring the status of the signaling device. Also disclosed is a method for installing a signal detection system in a wayside signaling system including a signaling device for monitoring a status of the signaling device. An apparatus for connecting a current sensor to a signaling device is also disclosed.

Signal detection system and method

A system and method provides for expanded monitoring and control of a railroad wayside interlocking system that monitors a plurality of track side and train systems and controls a plurality of train and track control devices with a primary control panel system communicating with the interlocking system over a first communication interface and with a remote control panel over a second communication interface, receiving interlocking status messages for visually displaying a current status state of the monitored systems, replicating the received interlocking status messages, determining a current status state for the control devices, communicating replicated interlocking status messages or the determined current status state over the second communication interface to one or more remote control panel systems, and receiving requests from the one or more remote control panel systems, which are then transmitted to the wayside interlocking system by the primary control panel system.

There is provided a voltage or current sensing device. An exemplary voltage or current sensing device includes a drive circuitry configured to deliver a drive current to a magnetic core operably coupled with a conductor, for driving the core to cyclical magnetic saturation. The device also includes sense circuitry configured to receive a voltage signal corresponding to an application current in the conductor. The device also includes signal processing circuitry configured to sample the voltage signal, wherein a first sample is in phase with the drive current and a second sample is out of phase with the drive current. The device also includes a feedback loop configured to deliver a compensation current to the magnetic core, wherein the compensation current is configured to balance the magnetic core and wherein the compensation current is based at least in part on the first sample in phase with the drive current.

Current sensor

There is provided a method of determining the state of a signal lamp. The method includes receiving time series data corresponding to an electrical signal used to power a signal lamp. The state of the signal lamp can switch from one of the following states to another of the following states: an on state, an off state, and a flashing state. The method also includes determining the state of the signal lamp, based at least in part on both the time series data and an amplitude value of the electrical signal relative to an amplitude-change threshold value over a determined number of amplitude changes.

Method and system for determining signal state

A portable computer system and method of operating a vehicle using the portable computer system in a communication-based train control (CBTC) system territory is provided. The portable computer system includes a sensor and a transceiver that is communicatively coupled to the sensor and to the CBTC system, wherein the portable computer system configured to be removably coupled to the vehicle. The method includes verifying that the vehicle is operating with one of a non-operational CBTC computer system and a non-CBTC computer system, and removably coupling a portable computer system including at least one sensor and a transceiver that is communicatively coupled to the sensor to the vehicle such that the transceiver is coupled in communication with the CBTC system.
