Abstract
A sensor unit for detecting the approach of a train, the sensor unit having first and second non-rail-mounted sensors, wherein the non-rail-mounted sensors are different from one another. A first control unit, itself having first and second non-rail-mounted sensors, wherein the non-rail-mounted sensors are different from one another in that they work on different physical principles, wherein the first sensor unit and first control unit are arranged to cooperate with one another to detect the approach of a train.
Claims12
A system for detecting the approach of a train, the system comprising:
- a first sensor unit for detecting the approach of a train, the first sensor unit comprising first (11) and second (12) non-rail-mounted sensors, wherein the first (11) and second (12) non-rail-mounted sensors are different from one another in that they work on different physical principles, and
- a first control unit, itself comprising first (21) and second (22) non-rail-mounted sensors, wherein the first (21) and second (22) non-rail-mounted sensors are different from one another in that they work on different physical principles,
- wherein the first sensor unit and first control unit are arranged to cooperate with one another to detect the approach of a train,
- the system being arranged to generate sensor information at first (11) and second (12) non-rail-mounted sensors of the first sensor unit, to compare the generated sensor information of the first (11) and second (12) non-rail-mounted sensors of the first sensor unit, and in the event of disagreement between the generated sensor information of the first (11) and second (12) non-rail-mounted sensors the of the first sensor unit, to use additional sensor information from the first control unit to confirm detection of approach of a train.
A method for detecting the approach of a train, the method comprising:
- generating sensor information at a sensor unit that comprises first (11) and second (12) non-rail-mounted sensors that are different from one another in that they work on different physical principles;
- comparing the generated sensor information of the first (11) and second (12) non-rail-mounted sensors, and
- in the event of disagreement between the generated sensor information, using additional sensor information from a control unit to confirm detection of approach of a train;
- wherein the control unit, itself comprising first (21) and second (22) non-rail-mounted sensors, wherein the first (21) and second (22) non-rail-mounted sensors are different from one another in that they work on different physical principles,
- wherein the sensor unit and control unit are arranged to cooperate with one another to detect the approach of a train.
