Embodiment Construction

[0031] Preferred embodiments of the invention are now discussed. While specific configurations of the present invention (ie, rail-guided vehicle systems) are discussed below, it should be understood that these are for illustration purposes only. Those skilled in the art will recognize that other components and configurations may be used without departing from the spirit and scope of the invention, such as applying the invention to other vehicles such as trams or street cars.

[0032] Reference attached figure 1 , the system includes a beacon sign 10 positioned along the length of the track 12, a train 20 having a sign reader 22 and a transmitter 24, and a wayside control unit 30 preferably sending information to all trains 20 in the area 14 .

[0033] A number of beacon marks 10 are arranged along the length of the track 12 of the area 14 consisting of a predetermined number of blocks 16 . A sign reader 22 located on the train 20 requests information from the beacon sign 10...

Abstract

A vehicle control system and method in which a plurality of beacon tags are disposed along a length of a track for a predetermine number of blocks. The beacon tags each provide information pertaining its location. Each vehicle that passes along the track has a tag reader that solicits information from the beacon tags and a transmitter that transmits the solicited information, as well as vehicle identification information for the transmitting vehicle, to a wayside control unit. The wayside control unit receives the transmitted position information and vehicle identification information and in turn transmits a single broadcast of information pertaining to each of the blocks of the predetermined number of blocks. This signal is received by all of the vehicles, which use only the information about immediately approaching blocks. In addition, dynamic tags located at positions along the length of the predetermine number of blocks can be used as a backup system for providing the same information that is provided by the wayside control unit.

Description

technical field [0001] Generally, the present invention relates to an improved vehicle control system and method. More specifically, the present invention relates directly to communication-based train control (CBTC) systems that utilize low-cost, readily available hardware to safely and efficiently control and guide various trains. Background technique [0002] For more than 100 years, people have controlled the operation of trains or other track-guided vehicles to enable a large number of trains to safely and efficiently run on the track network. Trains transport people and goods between locations separated by distances ranging from hundreds of feet to thousands of miles. When a single train is running on a single track or network of tracks, the control of the train becomes simpler since there are no obstacles. Since the train will rarely encounter other targets, the train can run at a maximum speed that is limited only by the train's speed performance, its ability to sto...
