SYSTEM TO DETERMINE THE RELATIVE POSITION BETWEEN VARIOUS VEHICLES

摘要

The train (5) has a lateral bar with electricity and there is another lateral bar (3) alongside the tracks, and this bar (3) begins five kilometres before the crossing level (2). When the train is approaching the lateral bar of the train side bar touches the bar (3) in the specific point (6), there is supply of electricity to the crossing level (2) and that means that a train (5) is near and the crossing level has electricity from the train to switch on the warning lights ans to close the gate. The crossing level and the train send messages to each other, to inform if the gate is closed or if there is any object blocking the crossing level. The train side bar (3) has also similar functions to the speed limit signals and to the railway red light signal. The train can send a radio message but just with a few kilometres range and when another train gets inside the radio range, each train begins to receive the message of the train. Each train has a logical analysis similar to a computer that is going to study the message, to check if there is danger or not of collision, and if there is, it warns the train driver. The system explained for the trains, it is also suitable for the cars and boats. The light house, big rocs in the sea or in the coast, buoys, etc, also transmit a radio message, that are analysed and if there is danger, it informs the pilot. With that analyze of the messages, the device can draw a map in a screen, and it also shows the relative future position of this objects.
