Publication distribution system |
摘要 |
A publication distribution system and, more specifically, a computer operated feedback control system for controlling a process such as a paper-making process includes an effective common data base to which Publisher and Subscriber means are connected. An actual Publisher and Subscriber data base allows for a once only subscription to link subscriber means to a selected publisher for transfer of only updated or changed data from the original. Thus, only changed data is transferred across a network and computational load is reduced significantly. In the specific context of the present invention, the Publisher may be a scanning sensor for basis weight of paper being manufactured by a paper-making machine and a Subscriber may be an actuator such as a headbox control unit.
