Title: Model electric railway control - uses time multiplex system supplying control data in parallel with power supply during controlled time periods
Inventor: KOLB HANS DR
IPC: H02P23/24
Filed: 1979-03-05
Abstract: The control system for an electric model railway uses the time multiplex principle. Control data are supplied to the various drive motors in parallel with their power supplies so that no separate periods are needed for control. These data are supplied in turn to the different motors and periodically returned. At the beginning of each return cycle, a synchronising signal is delivered. Each return cycle consists of a certain number of subperiods which is equal in number to the motors controlled, at least. These periods, beginning with the synchronising signal are counted within a given period of issue, and the control data are delivered within a period. The value of these periods is stored by an intermediate memory, while no new data are being supplied. The amt. of motor control data is delivered in a time period before a pulse arrives for starting the corresp. sub-period, using an analog control system.
