Title:
監視制御システム
Document Type and Number:
Japanese Patent JP6076279
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem in a supervisory control system connected by a multiple-system LAN network that the data communication concentrates on a specific LAN line to bring out heavy load state.SOLUTION: In a supervisory control system where a supervisory control server 1 outputting the supervision information by processing the supervision data from a supervisory device, and a plurality of supervisory terminals 2, 3 for displaying and supervising the supervision information sent from the supervisory control server are connected by the network of multiple LAN lines 4, 5, a LAN communication load determination unit 140 of the supervisory control server 1 determines a LAN line used by the supervisory control server and each supervisory terminal 2, 3, based on the communication load of the network and the amount of data transmission from the supervisory control server 1 and each supervisory terminal 2, 3. The supervisory control server 1 and each supervisory terminal 2, 3 set a LAN line by this determination results and perform data communication, thus reducing concentration of data communication on a specific LAN line.
