ABSTRACT:
A system and method for controlling a model train system and for defining a finite state machine for implementing control of the system. A computer (32) that is running a graphic user operating system is coupled through its serial port to a master control unit (MCU) (48). The MCU is coupled to slave control units (SCUs) (50, 52) and to a hand control unit (HCU) (152) through a token ring network (69) over which the computer transmits commands to energize selected track sections and to control the speed of locomotives (88, 90) running thereon. The MCU and SCUs are coupled to the sections of tracks and to electromagnetic switches (42, 44, 46) that determine the route of the trains over the sections of track. Furthermore, detector circuits (126) monitor a detector pulse to sense the presence of a locomotive or train on a particular section of track, producing an indicative output signal that is provided to the computer. The user graphically defines events, conditions, and control actions that are to be carried out on a visually displayed schedule manager grid. In addition, the user can graphically define a control panel that includes graphic controls, which can be manipulated by the user to establish the speed of a locomotive and to control the status of the electromagnetic switches. The control system can also be applied to control other systems that include electrically energized components.
