Abstract

The invention provides an excavating equipment health monitoring system and method, and belongs to the technical field of engineering machinery monitoring. The method comprises the steps that the working posture of the engineering machine is determined, and strain detection point data corresponding to a working device of the engineering machine under the working posture are acquired; determining load direction information according to strain data corresponding to at least two strain detection points in the strain detection point data, and obtaining load process data with the load direction information through the strain detection point data; and converting the load process data into stress statistical data of the working device, and evaluating the damage degree of the engineering machinerythrough the stress statistical data. The method is used for evaluating the health condition of the mining equipment working device.

Description

technical field [0001] The present invention relates to the technical field of construction machinery monitoring, in particular to a method for health monitoring of construction machinery, a signal acquisition method for health monitoring of excavation equipment, a system for health monitoring of construction machinery, a A health monitoring system for mining equipment, an equipment, a construction machine, and a computer-readable storage medium. Background technique [0002] Hydraulic excavator is one of the most widely used construction machinery with the largest production and sales volume. It is widely used in the construction of energy, water conservancy, transportation, construction and other basic projects. It is an important construction product in the process of national construction; according to statistics, more than 60% of the Earthwork excavation is done by hydraulic excavators. [0003] The service load of the excavator is complex and changeable, and the worki...
