Finding the ideal point of acceleration
Problem early or late acceleration
Efficiency and safety are the main requirements of rail transport as a sustainable and future-oriented transport route for the transport of goods or persons. Increasing transport volume and passenger volume requires ever longer trains. Especially when cornering the trains is the challenge to find the optimal point of acceleration. Often it is impossible for the train drivers to know when the entire train has left a curve or passed its vertex. Both premature and delayed acceleration in the curve have negative effects on train safety or on cycle times and train availability.
Sensors for optimal acceleration
The CoriSENS rotation rate sensor is designed to provide an effective way to detect cornering. therefore, CoriSENS measures the angular velocity of a train car's rotation about its vertical axis. These measured values are passed on to the train control. When falling below a certain angular velocity then a signal can be given, which indicates to the driver to reach the curve output of the last car. Then it can be accelerated again safely.
- Relief of the train driver through effective assistance system
- Increased efficiency when training new train drivers
- Improvement of transport safety
Single axis angular rate sensor to measure angular velocity
- Integrated self-test function
- Temperature compensation without active heating or cooling
- OEM Adaptation of various parameters
CoriSENS is a single axis angular rate sensor based upon MEMS technology (micro-electromechanical system) capturing the angular velocity of the rotation around its measurement axis. A spring-mass-system continuously measures the displacement of a seismic mass, induced to high frequency vibration. This value is proportional to the angular velocity and subsequently output with either a 4-20 mA current signal or a 0-10 V voltage signal.
- Measurement range ±12 °/s (adjustable)
- Current output 4-20 mA
- Voltage output 0-10 V
- Protection class IP42
- Temperature range -40 °C…+85 °C
