Abstract
A transmitter mounted on trains/vehicles to warn personnel in the path of an oncoming train or vehicle of the train or vehicle's approach. A receiver mounted in the train/vehicle to warn the driver that personnel are in the path of the train/vehicle. A transmitter carried or placed near personnel in the path of approaching trains/vehicles to warn the driver of the approaching train/vehicle that personnel are in the path of the approaching train/vehicle. A receiver carried or placed near personnel in the path of approaching trains/vehicles to warn them of the approaching trains/vehicles. The personnel in the path of the oncoming train or vehicle can also transmit a signal to inform the driver of the oncoming train/vehicle that they are aware of its approach.
Description
ONCOMING TRAIN/VEHICLE WARNING DEVICE
This invention relates to a signal transmitted by a
Transmitter/Receiver on trains/vehicles or any form of moving transport, and receivedby personnel in the path of the train/vehicle or any form of moving transport by, Mobile
Receiver/Transmitters they will be carrying to warn them of the approaching trains/vehicles or any other form of moving transport.
This invention also relates to a signal transmitted by the
Mobile Receiver/Transmitter and received by the
Transmitter/Receiver mounted on approaching train/vehicle or any other form of moving transport that will warn the approaching train/vehicle or any other form of moving transport of personnel in the approaching train/vehicle's path.
The warning time period can be varied by increasing or decreasing the transmitted signal strength.
As the Oncoming Train/Vehicle Warning Device is related to safety all components will preferably by duplicated.
The following components will be required to produce a basic early warning of oncoming trains/vehicles or any other form of moving transport although components can be added to enhance it's capabilities. Components can also be deleted or adapted to suit a specific tailor made system: TRA NSAHTTER/RECEIVER The Transmitter/Receiver can be fitted on top, to one or both ends of a train/vehicle or any position on the train/vehicle that gives a clear transmission path for the transmitted signal.
The signal frequency would depend upon what frequencies are available in the area of use.
It would be preferable for the Transmitter/Receiver to be capable of receiving warnings of more than one Mobile
Receiver/ Transmitter in it's path and could take the form mentioned for Mobile Receiver/Transmitter warning of more than one approaching train/vehicle.
An information device may be installed in the
Transmitter/Receiver to inform the driver that the personnel in the path of the train/vehicle are aware of it's approach.
The information device could take the form of a buzzer, a flashing light, or any other type of device. The information device should be able to be activated by personnel in the path of the approaching train/vehicle to inform the driver that they are aware of the oncoming train/vehicle.
It would be preferable to install at least two warning lights to inform the driver that the Transmitter/Receiver is:
1. Functioning correctly
2. The Transmitter/Receiver is faulty STANDBY TRANSAIITTER/RECEIVER Preferably a Standby Transmitter/Receiver would be installed wherever a Transmitter/Receiver is installed.
The Standby Transmitter/Receiver would have the same frequency and be a replica of the Transmitter/Receiver.
It would be preferable for The Standby Transmitter/Receiver to be activated automatically should The Transmitter/Receiver develop a fault.
To increase the safety aspect there can be any number of warning lights but it would be preferable for The Standby
Transmitter/Receiver to have at least three warning lights.
The lights would inform the driver that:
1. The Standby Transmitter/Receiver was functioning.
2. The Standby Transmitter/Receiver was in operational
use.
3. The Standby Transmitter/Receiver is faulty.
MOBILE RECEIVER/TRANSMITTER
The Mobile Receiver/Transmitter would preferably be encased in a small tough, waterproof case although it's shape could take any form ad be made from a variety of materials.
The Mobile Receiver/Transmitter may be clipped onto a belt or item of clothing of the wearer.
The Mobile Receiver/Transmitter may also be used in a static position where it can mounted in any number of places to warn personnel of an oncoming train/vehicle.
The Mobile Receiver/Transmitter may be mounted on the end of a pole whereby the polo may be driven into the ground.
The Mobile/Receiver/Transmitter mounted on the pole would inform a group of people of an approaching train/vehicle.
The Mobile Receiver/Transmitter would receive the signal transmitted by oncoming trains/vehicles and give an audible warning of any desired noise or volume strength to the personnel in the path of the oncoming train/vehicle.
In very noisy areas earphones could be worn to enable the wearer of the Receiver to hear the audible alarm warning him of an oncoming train/vehicle.
The earphones would preferably have a twist and lock mechanism fitted to prevent the earphones from becoming unplugged accidentally.
A vibrating device could also be fitted to the Mobile
Receiver/Transmitter in noisy areas which, upon receiving the signal transmitted by an oncoming train/vehicle would vibrate and warn the wearer of the Mobile Receiver/Transmitter of an approaching train/vehicle.
The vibrating device would have to be worn close to the body of the wearer.
The Mobile Receiver/Transmitter could adapted to incorporate one more different types of warning devices.
It would by preferable for the Mobile Receiver/Transmitter to have duplicate circuits and parts which would automatically be activated should the initial circuits or parts developea fault.
The Receiver/Transmitter would preferably have the capacity to warn of one or more approaching trains/vehicles at the same time.
This could take the form of an increase in the audible tone for the second or subsequent approaching train/vehicle, or an increase in the vibration pitch, or whatever method is being used to warn personnel of the approaching second or subsequent oncoming train/vehicle.
It would be preferable for the Mobile Receiver/Transmitter to have a selected frequency which could be transmitted by pressing a button, or any other type of device of activate the information warning device of the approaching train/vehicle.
This would inform the driver of the approaching train/vehicle that the personnel in it's path are aware of it's approach.
To test the Mobile Receiver/Transmitter a 'Press to Test' button could be installed.
Upon pressing the 'Press to Test' button, the audible or vibrating warning or any other warning device in use would be activated to inform the wearer the Mobile Receiver/Transmitter is functioning correctly.
To inform the wearer of the Mobile Receiver/Transmitter that a fault has occurred on the Mobile Receiver/Transmitter whilst they are wearing the Mobile Receiver/Transmitter, a tone or vibration pitch, different to the one transmitted by the approaching train/vehicle could be incorporated.
It would be preferable to install a warning device in the
Receiver/Transmitter to inform the wearer of low battery power.
REFLECTOR
Where the track or road curves there would be a risk of the receivers not receiving the transmitted signal. Reflectors would have to be sited at strategic positions on the curves to reflect the transmitted signal around the curve. The
Reflector locations would become apparent during the initial coverage trials.
Other modifications and embodiments of the invention will be readily apparent of those skilled in this art. All such modifications and embodiments are to be deemed within the ambit and scope of the invention and the invention is not to be deemed limited to the particular embodiment(s) hereinbefore described which may be varied in construction and detail without departing from the scope of the patent monopoly hereby sought.
Claims (7)
1. A transmitter and receiver mounted at the front
and/or the back or any other position on a
train/vehicle that will transmit and receive
specific radio transmissions.
2. A mobile receiver and transmitter that may be
combined in the same case that will transmit and
receive radio transmissions to or from approaching
trains/vehicles.
3. The train receiver will receive the signal
transmitted by the mobile transmitter.
4. The mobile receiver will receive the signal
transmitted by the train/vehicle transmitter.
5. A device incorporated in the mobile
receiver/transmitter to inform the driver of the
approaching train/vehicle that the personnel in the
path of the approaching train/vehicle are aware of
it's approach.
6. A reflector will have to be placed on curves to
reflect the transmitted signal around the curves.
7. The system can be adapted to suit any form of mobile
transport.
