Abstract

An apparatus for use in a railway train simulator includes a control station which has a first microcomputer for receiving and transmitting, via a conventional transmission protocol, train simulation signals to a second microcomputer. The second microcomputer provides master control for the apparatus. The second microcomputer is adapted to link with and operate from multiple control stations and multiple computer control terminals. Information is provided in an enhanced manner through one or more color graphics terminals, plotters and printers. Displays of simulated trains and track selections can be displayed at different, selectable scales.

Claims

1. An apparatus for use in simulating operation and control of a railway train, comprising:

a control station including;

a plurality of train operating controls, each for providing a respective signal related to the degree of operation thereof by a control station operator; and

a first computer connected to said plurality of train operating controls so that a plurality of signal transmission circuits, over which the respective signals from said train operating controls are communicable to said first computer, are defined;

display means for displaying alphanumeric data and graphical representations to depict the operation and control of a railway train to be simulated;

a second computer including an output connected to said display means; and

serial communication link means for connecting said first computer and said second computer so that a serial signal communication circuit, over which any of the respective signals communicable to said first computer are communicable to said second computer from said first computer, is defined between said first and second computers.

2. An apparatus as defined in claim 1, wherein said second computer further includes a plurality of serial data input ports adapted to be connected to a plurality of control stations, one of said serial data input ports connected to said serial communication link means.

3. An apparatus as defined in claim 1, wherein:

said apparatus further comprises a computer control terminal including a cathode ray tube display screen and a keyboard connected thereto; and

said second computer further includes a plurality of computer control terminal input ports adapted to be connected to a plurality of computer control terminals, one of said computer control terminal input ports connected to said computer control terminal which includes said cathode ray tube display screen and said keyboard.

4. An apparatus as defined in claim 1, wherein:

said display means includes a color graphics terminal connected to said second computer; and

said apparatus further comprises;

a printer connected to said second computer so that alphanumeric data displayed through said color graphics terminal are printable onto hard copy; and

a plotter connected to said second computer so that graphical representations displayed through said color graphics terminal are plottable onto hard copy.

5. An apparatus as defined in claim 1, further comprising means for controlling the mode of operation of said second computer, said means connected to said second computer and including a visual display screen, distinct from said display means, and a keyboard connected with said visual display screen.

6. An apparatus for use in simulating operation and control of a railway train, comprising:

a first control station, including;

a first microcomputer including a plurality of input ports and an RS-232 output port to which data received at said input ports are transferred;

a first power throttle connected to a first one of said input ports of said first microcomputer;

a first dynamic brake control connected to a second one of said input ports of said first microcomputer;

a first independent locomotive air brake valve connected to a fourth one of said input ports of said first microcomputer; and

a first sanding wobble stick connected to a fifth one of said input ports of said first microcomputer;

a second control station, including;

a second microcomputer including a plurality of input ports and an RS-232 output port to which data received at said input ports of said second microcomputer are transferred;

a second power throttle connected to a first one of said input ports of said second microcomputer;

a second dynamic brake control connected to a second one of said input ports of said second microcomputer;

a second train line air brake valve connected to a third one of said input ports of said second microcomputer;

a second independent locomotive air brake valve connected to a fourth one of said input ports of said second microcomputer; and

a second sanding wobble stick connected to a fifth one of said input ports of said second microcomputer;

a third microcomputer, including;

a first RS-232 input port connected to said RS-232 output port of said first microcomputer;

a second RS-232 input port connected to said RS-232 port of said second microcomputer;

a first control input port;

a second control input port; and

a plurality of output ports;

a first computer control terminal, including a first cathode ray tube screen and a first keyboard, connected to said first control input port of said second microcomputer;

a second computer control terminal, including a second cathode ray tube screen and a second keyboard, connected to said second control input port of said second microcomputer;

a color graphics display terminal connected to a first one of said output ports of said third microcomputer;

a plotter connected to a second one of said output ports of said third microcomputer; and

a printer connected to a third one of said output ports of said third microcomputer.
