ABNORMALITY DIAGNOSTIC SYSTEM FOR WORK SYSTEM OF CONSTRUCTION MACHINERY AND METHOD USING THE SAME

摘要

An abnormality diagnostic system for a work system of construction machinery includes an input portion configured to receive state information of an engine, a hydraulic pump and a work apparatus of the construction machinery, a controller configured to calculate and mutually compare horsepower information of the engine, the hydraulic pump and the work apparatus from the received state information, and if the horsepower information are different from each other by a preset range or more, determine whether or not abnormality occurs in any one of the engine, the hydraulic pump and the work apparatus corresponding thereto, and an output portion configured to output the determination result of abnormality.;Accordingly, an abnormal situation of the construction machinery may be precisely diagnosed and notified immediately to be able to make a quick response, and further, a manufacturer of the construction machinery may collect the abnormality situation data to database to reflect in a product design.
