Embodiment Construction

[0025] Hereinafter, a working machine management system according to an embodiment of the present invention will be described. In this embodiment, the present invention is applied to a crawler-type hydraulic excavator as a working machine, and whether or not an abnormality occurs is determined based on the distance between the front working machine of the hydraulic excavator and the construction target surface (target surface distance). In addition, in each figure, the same code|symbol is attached|subjected to the same component, and overlapping description is abbreviate|omitted suitably. In addition, in the following description, when there are a plurality of equivalent components, lowercase letters may be added at the end of the reference numerals, and the lowercase letters may be omitted to collectively express the plurality of components. For example, when there are three equivalent valves 10 a , 10 a , and 10 a , they may be collectively expressed as the valve 10 .

Abstract

Provided is a hydraulic shovel comprising a control controller that computes the magnitude of a positional difference in the height direction of a front work machine and a construction target face, such computation being on the basis of the position of the construction target face, the position of a vehicle main body computed by a GNSS receiver, and the attitude of the front work machine detected by an attitude sensor, wherein when the magnitude of the positional difference exceeds a prescribed value d1, the control controller: records, in a storage device, snapshot data of information relating to an operation sensor, a pressure sensor, an attitude sensor, the GNSS receiver, and a wireless device, in a prescribed period based on the foregoing prescribed value exceeding time; and on the basis of the snapshot data, diagnoses the cause of the magnitude of the positional difference exceeding the prescribed value.

Description

technical field [0001] The present invention relates to work machines. Background technique [0002] In recent years, the introduction of information-based construction has been promoted at construction sites. Information-based construction refers to a system that focuses on construction and utilizes electronic information in the processes of survey and design, construction, inspection, and management, and realizes efficient construction through ICT (Information and Communication Technology). As a work machine that supports information-based construction, there is known one equipped with a guidance function that displays information on the position of the vehicle body, the posture of the front work machine, and the position of the construction target surface on a monitor, and prevents the intrusion of the bucket positioned at the front end of the front work machine. A hydraulic excavator with mechanical control functions below the construction target surface. Such a workin...
