Method and system for remote supervisory control

Claim 1

A method for remote supervisory control, in which there are a plurality of slave systems, each of said slave systems having a plurality of individual control points in its purview, and performing monitoring of and control of the statuses of each of the individual control points, and a master system which is connected to each of said slave systems via channels, and which performs overall monitoring of the statuses of, or control with respect to, said plurality of individual control points of each of the slave systems, wherein: in each said slave system said plurality of individual control points are divided beforehand into groups of individual control points having the same attribute; a pre-established operation is performed beforehand With respect to said statuses of said plurality of individual control points of each divided group, the results of said operation being taken as the status of a representative control point which represents said group; and further wherein by notifying said master system of the status of said representative control point, overall monitoring is performed with respect to said plurality of individual control points.

Claim 2

A method for remote supervisory control, in which there are a plurality of slave systems, each of said slave systems having a plurality of individual control points in its purview, and performing monitoring of and control of the statuses of each of the individual control points, and a master system which is connected to each of said slave systems via channels, and which performs overall monitoring of the statuses of, or control with respect to, said plurality of individual control points of each of the slave systems, wherein: in each said slave system said plurality of individual control points are divided beforehand into groups of individual control points having the same attribute; a pre-established operation is performed beforehand With respect to said statuses of said plurality of individual control points of each divided group, the results of said operation being taken as the status of a representative control point which represents said group; and further wherein by notifying said master system of the status of said representative control point, overall monitoring is performed with respect to said plurality of individual control points.

Claim 10

A system for remote supervisory control, comprising a plurality of slave systems, each of said slave systems having a plurality of individual control points in its purview, and performing monitoring of and control of the statuses of each of the individual control points, and a master system which is connected to each of said slave systems via channels, and which performs overall monitoring of the statuses of, or control with respect to, said plurality of individual control points of each of the slave systems, wherein each of said slave system comprises: an individual control point table which holds information related to the statuses of each individual control point, which are collected from each said individual control point; a representative control point table holding statuses which represent a group of a plurality of said individual control points having the same attributes; a slave-side status change processing means which, when there is a status change in the information related to the statuses of each individual control point collected from each said individual control point, supplies that information as is to said individual control point table, and which supplies said representative control point table with said information after a pre-established operation is performed with respect to said statuses of said plurality of individual control points; a slave-side representative point configuration file into which are minimally stored the correspondence relationship between said representative control point and said individual control points which belong to it and an arithmetic expression which defines said operation; and a slave-side expansion/restoration processing means which works in concert with said individual control point table, said representative control point table, and said slave-side representative point configuration file either to expand processing with respect to a representative control point to processing of said individual control points or to restore processing with respect to expanded individual control point to processing with respect to said representative control point.

Claim 11

A system for remote supervisory control, comprising a plurality of slave systems, each of said slave systems having a plurality of individual control points in its purview, and performing monitoring of and control of the statuses of each of the individual control points, and a master system which is connected to each of said slave systems via channels, and which performs overall monitoring of the statuses of, or control with respect to, said plurality of individual control points of each of the slave systems, wherein each of said slave system comprises: an individual control point table which holds information related to the statuses of each individual control point, which are collected from each said individual control point; a representative control point table holding statuses which represent a group of a plurality of said individual control points having the same attributes; a slave-side status change processing means which, when there is a status change in the information related to the statuses of each individual control point collected from each said individual control point, supplies that information as is to said individual control point table, and which supplies said representative control point table with said information after a pre-established operation is performed with respect to said statuses of said plurality of individual control points; a slave-side representative point configuration file into which are minimally stored the correspondence relationship between said representative control point and said individual control points which belong to it and an arithmetic expression which defines said operation; and a slave-side expansion/restoration processing means which works in concert with said individual control point table, said representative control point table, and said slave-side representative point configuration file either to expand processing with respect to a representative control point to processing of said individual control points or to restore processing with respect to expanded individual control point to processing with respect to said representative control point.

Claim 12

A system for remote supervisory control, comprising a plurality of slave systems, each of said slave systems having a plurality of individual control points in its purview, and performing monitoring of and control of the statuses of each of the individual control points, and a master system which is connected to each of said slave systems via channels, and which performs overall monitoring of the statuses of, or control with respect to, said plurality of individual control points of each of the slave systems, wherein said master system comprises: a common control point table holding in common both information related to a status which represents the statuses of each of a plurality of grouped individual control points which have the same attribute and information related to the status of and collected from said individual control points; a master-side representative point configuration file into which are stored minimally both the relationship of a representative control point representing said grouped individual control points and said individual control points which belong thereto and address information which specifies dynamically expanded or compressed storage area of said common control point table; a master-side expansion/restoration processing means which works in concert with said common control point table and a slave-side representative point configuration file either to expand processing with respect to a representative control point to processing of said individual control points or to restore processing with respect to expanded individual control points to processing with respect to said representative control point; and a master-side status change processing means which performs overwriting of said status in said common control point table each time there is a change therein, and which, in the case in which expansion of processing with respect to a representative control point to processing of said individual control points or restoration of processing with respect to expanded individual control points to processing with respect to said representative control point is to be performed, references said master-side representative point configuration file to perform the overwriting of said status.

Claim 13

A system for remote supervisory control, comprising a plurality of slave systems, each of said slave systems having a plurality of individual control points in its purview, and performing monitoring of and control of the statuses of each of the individual control points, and a master system which is connected to each of said slave systems via channels, and which performs overall monitoring of the statuses of, or control with respect to, said plurality of individual control points of each of the slave systems, wherein said master system comprises: a common control point table holding in common both information related to a status which represents the statuses of each of a plurality of grouped individual control points which have the same attribute and information related to the status of and collected from said individual control points; a master-side representative point configuration file into which are stored minimally both the relationship of a representative control point representing said grouped individual control points and said individual control points which belong thereto and address information which specifies dynamically expanded or compressed storage area of said common control point table; a master-side expansion/restoration processing means which works in concert with said common control point table and a slave-side representative point configuration file either to expand processing with respect to a representative control point to processing of said individual control points or to restore processing with respect to expanded individual control points to processing with respect to said representative control point; and a master-side status change processing means which performs overwriting of said status in said common control point table each time there is a change therein, and which, in the case in which expansion of processing with respect to a representative control point to processing of said individual control points or restoration of processing with respect to expanded individual control points to processing with respect to said representative control point is to be performed, references said master-side representative point configuration file to perform the overwriting of said status.
