Abstract
In an onboard train safety device, a passive vibrational device 11 constantly listens for other trains on the same track. An active vibrational device 13 constantly sends out the train's identity information. Digital signal analysis is carried out so that relevant information such as trains on the same track and position relative to station or other trains may be obtained. Subsequently relative speeds of trains may be formulated. <IMAGE>
Description
ROLLING STO@K SAFETY @EVICE This invention relates to all rail transport.
Currently the safety of trains is bases upon driver skills trained staff within the rail network set procedures and an array of safety precautions. It has been proved that however safety concious a system is it can rea down and consequently nationai disasters suca as train head on collisions can occur.
This safety device would enhance and improve the current safety etandards within the rail network; and so avoiainS head on collisions.
The invention is to use and enhance the acoustic signature a train passes to the rail lines by travelling a@ong it. The signature can be noticed for instance whilst waiting for a train. A random noise sound is heard moments beiore the train arrives or is even seen. Consequently the decision that a train is coming can no mate. This random noise run passed
to the rail increases in intensity and noise leval as the train approaches. After the train has passed a similar @ound is again heard this is illustrated in figure(1).
This current human activity desoribed is to be transformed as the invention into the form of a safety devire.
The invention is to have a passive accel@erometer or similiar passive @istenting device fitted to trains so that the acoustir signature can be read digitally. As part of the invention the signal or acoustic trace emmited by a train courd be enhanced by using an electronic active device which is to transpond the exact identity of a train details such as train destiny and time of arrival could be relevant information.
The fact that the train is on the same line established and subsequently the relevant satiety precautions or safety measures mate automaticly and so avoiding a nead on collision.
A specific embodiement of the invention will now be described by way of example with reference to the accompanying drawings in which:
Figure(1) Acoustic signature passed to the rail lines by a
train
Figure(2) illustrates the probable situation of he safety
device fitted to a train
Figure(3) in perspective the safety device.
Figure(4) The output of the lisening device.
Figure(5) The output of the transponder.
Reffering to the drawing figure(3). A basic requirement of the device is to keep the roller i~- t in constant contact with tat track so that a measurement an we mace with the transducer accellerometer which is fixed verticlly as crose to the roller as possible so that the best real time measurements maybe obtained. Best being a clear signal. The shock absorber 9 is to take and absorb harmful@ shocks from destroying or damaging the device. Another reature Or tie shock absorber is to keep the roller in constant contact with the track as the train is moving.The roller is to be made of a suitable material that can withstand the abrasive and rigerous duty of being in constant contact with the rail line. The roller should be allowed to move freely on bearings pivoted at pivot point 14.
The output of the accellerometer @@ is to be processed by the control box 15. Where subsequent signal processing is to be carried out module 1 is the first phase of the processing where the signal is amplified by a charge pre-amplifier. Having amplified the signature frequency analysis fast fourier transforms are enabled giving a real time frequency analysis or tat signature figure(4) illustrates this digital filters are then used to surpress unwanted noise and identifies tat relevant tart of the signature.
The microprocessor module3 is then activated which analyses the results and makes the relevant decisions which is then passed to the driver by the display screen 16 for an overview ol the current action.
The current identity of the train departure time,arrival time, departure from maybe typed into the device at 16. Which then activates the transponder at 13 which transmits the trains identity. Which is to be of such an amplitude and frequency so that it maybe picked up Dy another device on another train. The principal of this is snown in figure(5). The signal is generated by the signal generator at 6 which is activated by the driver at the screen 16. @he signal is then boosted by a power amplifier at 7 and c. lie transponded signal should be of a high frequency and amplitude not to be considered harmfull or hazerdous and yet unique in this spectrum leval and region that it can be identified by another unit.
A fan is required at 5 to keep the system at a tool temperature.
Claims (5)
1. To use the acostic spectrum passed from a train to
the track for the sa@ety of trains.
2. To enhance the naturai acoustic spectrum of a train
on the same line by the use of an active vibrationai device which subsequently can identify
exact information about the train such as departure
time, departing from, arrival time, arriving from.
3. Increase the safety of rail travel.
4. An onboard train safety device which constantly
listens for other trains on the same track am so
avoiding head on collisions by giving constant ant
real data ensuring the safety of trains.
5. The position of a train on the same track can De
identified and its oncoming or outgoing speet maybe
determined.
