MICROPROCESSOR CONTROLLED RAILWAY SIGNALLING INTERLOCK

With the goal of establishing applicability of microprocessors in fields which have traditionally relied upon electromagnetic relays for logic functions, one of the commercially available microprocessor assemblies was interfaced with a specially designed display panel to illustrate the concept of a microprocessor controlled railway signaling interlock. The MPU was programmed to scan the status of the simulated block occupancy switches and display appropriate speed signals.
