  • Hierarchical computer system for generating selective output signals in response to received input signals
    Patent number: 4434460
    Abstract: Hierarchical three-level computer system for receiving input messages from signal sources (23) and for conditionally activating output devices (26) according to input messages; the system comprising a host computer (15), a terminal computer (27) and a number of micro computers (22). The central computer enters condition tables into specific storage modules (2A-2E) within the terminal computer. These tables can be displayed on the terminal computer screen (10) and may be updated from the terminal computer keyboard (8). The micro computer receives input signals from a signal source (22) and composes input messages, which are transferred to the terminal computer. The terminal computer makes a comparison between input messages and condition table data and selectively activates the output devices (26).A specific up and down counting apparatus within the micro computer enables a simultaneous signal detection and data processing operation.
