A SHORT-RANGE DIGITAL TELEMETRY SYSTEM FOR REMOTE POSITIONING REGULATOR CONTROLLERS,
Abstract
A remote system of multipoint process control is described, in which communication between the command center and its controlled stations is done via telemetry. Either existing telephone lines in the plant or added TM lines may be used. Control points are queried sequentially in binary code as to the correctness of their position, or are commanded to new set points on the basis of central computer calculations. The coded words used are the following: station address, task, proof of correctness, and verifications 'message received' and 'correction made', and a break-off command. The method applies to electric or hydraulic motor controllers with voltage feedback to the summing point. An operating system described uses type RD-09 two-phase asynchronous control motors with 120-ohm potentiometer feedback. The system error is claimed not to exceed 1.5 percent. (Author)
