Summary:The present invention relates to an automatic control system for diagnosing and predicting failure and managing a remaining life by Pearson correlation coefficient analysis which can minimize an equipment downtime by predicting the generation of failure through failure diagnosis, transition analysis, and lift management based on load and efficiency and previously notifying an equipment manager of the generation of the failure. A system in the present invention comprises: a measuring unit for sensing and editing a device state and failure factors according to load; a load equipment information database for storing the information of load equipment; a computing unit for computing the efficiency of operation and the state of the failure factor by design according to the load by using the information of the load equipment information database; an analyzing unit for analyzing correlation between the measuring unit and the computing unit; a displaying unit for displaying failure and life data analyzed by the analyzing unit; an editing unit for editing remotely transmitted content in the displayed content; and a transmitting unit for transmitting, to the outside, data edited by the editing unit. The present invention has the effect that it can prevent an accident by notifying the equipment manager and user of time when a failure is predicted before the failure occurs through failure diagnosis, transition analysis, and life management based on load and efficiency, and can improve the efficiency of operation by minimizing the equipment downtime.
