Abstract

Generating apparatus and method by which all steps of the procedure for generating a configuration diagram of connection between a plurality of units constituting a system can be automated. The automatic connection configuration diagram generating system comprises a first memory for storing data indicative of the units by which the system is constituted, a second memory for storing data indicative of a layout according to which the units of the system are laid, a knowledge base for incorporating a set of rules indicative of connection specifications for all of the units of the system, a selector for selecting connection specification rules for desired units from the rule set stored in the knowledge base, a controller for determining a connection structure on the basis of the selected rules and the data stored in the first and second memories, and a third memory for storing the connection structure determined by the controller.

Claims

1. An apparatus for automatically generating a configuration diagram of connection between a plurality of units constituting a system, comprising:

first memory means for storing data indicative of said units by which said system is constituted;

second memory means for storing a data structure indicative of a layout according to which said units of said system are to be laid out using cable;

a knowledge base for incorporating a set of rules indicative of connection specifications for all of said units of said system;

means for selecting connection specification rules for desired units from the rules set stored in said knowledge base;

control means for determining a connection structure on the basis of the selected rules and the data stored in said first and second memory means; and

third memory means for storing the connection structure determined by said control means;

wherein said control means includes means for generating connector information from said selected connection specification rules and data read out of said first memory means, means for determining the position of connectors on the basis of data read out of said second memory means, means for sorting said connector information in accordance with connector attributes, and means for determining the connection destination of each unit and each cable, the kind of cable and the length of cable on the basis of said connection specification rules.

2. An apparatus for automatically generating a configuration diagram according to claim 1, wherein said system is an electronic computer system, said data stored in said first memory means includes the type name for identifying the individual units constituting said computer system, the machine number indicative of a central processing unit (CPU) to which the individual units are coupled, the device address of said CPU coupled with each unit and data indicating whether each unit is an annexed unit, said data stored in said second memory means includes the type name of each unit and data indicative of the geometrical position of each unit relative to a reference position, and said knowledge base stores a data including data concerning the type name and attribute of each unit, data concerning the attribute and position of connectors possessed by each unit, data concerning the type name and attribute of each cable for interconnection between the respective units and data concerning the cable attribute and wiring attribute of connectors possessed by each cable.

3. A method of automatically generating a configuration diagram of connection between a plurality of units constituting a system, comprising the steps of:

storing data indicative of said units by which said system is constituted in first memory means;

storing data indicative of a layout according to which said units of said system are to be laid out;

storing a set of rules indicative of connection specifications for all of said units of said system in a knowledge base;

reading said data concerning a system assembly from said first memory means;

generating connector information on the basis of said rule set and said data read out of said first memory means;

reading said data indicative of the layout of said units from said second memory means;

determining the position of connectors on the basis of said data read out of said second memory means and adding the determined connector position to said connector information;

sorting said connector information in accordance with a connector attribute; and

determining the connection destination of each unit and each cable, the kind of cable and the length of cable according to said connector attribute on the basis of the connection rules stored in said knowledge base.
