Production process control system in newspaper printing

摘要

A production process control system for a news printing system using rotary presses comprising a press control subsystem, a sorting and delivery control subsystem, at least any one of a printing plate transportation control subsystem, a newsprint roll storage control subsystem, a mailroom materials supply control supply control subsystem and a truck yard bundle sorting control subsystem, and a production process control system for supervising and controlling each of said control subsystems. The stations provided in the production process control system and the control subsystems are linked with each other via a ring-like data highway network. Each of the stations are equipped with a processor or an intelligent input/output control unit, so that each of the production process control systems and the control subsystems can execute necessary data processing while communicating with each other. The production process control system can supervise and control the processing carried out by each of said other control subsystems. In addition, a circulation control subsystem relating to newspaper sales business processing is connected with the production process control system via a circuit separated from the data highway network.
