Interface Middleware System Having Cluster Architecture for Smart Factory Platform

摘要

A clustering structure interface middleware system for a smart factory platform according to an aspect of the present invention capable of collecting data without losing data by duplicating a plurality of receiving processes for each process, operates in an active state, and communicates with each other differently. A first interface middleware server including a plurality of first receiving processes for acquiring collected data from a data collecting device according to a protocol; A second interface middleware server operating in an active state to form a cluster structure with the first interface middleware server, and including a plurality of second processes identical to the plurality of first receiving processes; And only the first receiving process in which the error occurred among the first receiving processes set as the master is selectively switched to the slave, and the second receiving process corresponding to the first receiving process in which the error occurs among the second receiving processes set as the slave. It characterized in that it comprises a receiving control unit for selectively converting only the process to the master.
