<p>CM-77884 SUPERVISORY CONTROL SYSTEM An automatic supervisory control system is arranged to provide monitoring and supervisory functions in a noisy electrical environment over communication channels which are also noisy and generally highly congested. The system is designed to handle a large number of status monitoring stations which provide status signals, a relatively small number of display elements, memory elements for storing the status signals and control means for enabling the status stations, the memory elements and the display elements so that the large numbers of status signals can be stored, read out, and displayed in a relatively small number of display elements on a closed loop basis without destroying status signals until responsive action has been taken on the status signals. The system includes a central control station linked to a plurality of status stations by a single dedicated or shared radio channel, a plurality of telephone wire lines, or a combination of both. A coded signal is used to communicate status signals and command signals between the central control station and the status stations. The central control station includes the status display elements, the memory elements, an audible alarm indicator, printed status and command reports, a keyboard for data entry and a computer for controlling system operation.</p> |
