Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] In order to solve the problem that the effective working section in the prior art is difficult to identify, the present invention provides a method for identifying the effective working section of the loader, according to the meaning of the effective working section and combined with the actually collected boom cavity pressure and bucket size The characteristics of cavity pressure etc. are used to define the time range of effective operation segment.

[0030] The effective operation section refers to the operation process closely related to the operation conditions and the operation environment in the operation process. In order to better realize the segmentation, combined with the requirement of identification of operating conditions, the present invention proposes a method for segmenting effective operating segments, and performs segm...

Abstract

The invention relates to a method for identifying an effective working section of a loader. The steps are as follows: 1) Acquiring the pressure signal of the large cavity of the turning bucket and the pressure signal of the large cavity of the boom from the loader, and extracting the pressure signal of the large cavity of the turning bucket and the pressure signal of the large cavity of the boom 2) According to the obtained operation cycle, the operation segment in the operation cycle is extracted according to the characteristic information of the predefined effective operation segment, and the identification of the effective operation segment is realized. The invention defines the effective operation section and divides the operation stage of the loader, which is beneficial to realize the analysis of the operation process, especially the analysis of the identification of the operation condition. And based on the characteristic information of the effective operation section, the identification of the effective operation section of the operation spectrum is realized; the identification of the effective operation section plays a role in laying the foundation for the analysis of the operation conditions, the data analysis and compilation of the operation spectrum; it is conducive to the realization of the operation The refinement of spectrum data facilitates statistical analysis and makes job spectrum data more regular.

Description

technical field [0001] The invention relates to a method for identifying an effective operation section of an engineering vehicle, and more specifically, relates to a method for identifying an effective operation section in a loader shovel loading process. Background technique [0002] With the rapid advancement of large-scale national projects such as mining, construction, water conservancy and hydropower, high-speed railway network, highway network, and South-to-North Water Diversion, the production, sales and inventory of engineering vehicles have increased rapidly, and construction machinery has developed extremely rapidly. More than 95% of construction machinery products adopt hydraulic transmission in order to obtain large torque and large inertia load requirements. Due to the harsh working environment, complex and changeable working conditions, and the continuous improvement of equipment automation and informatization, how to ensure the reliability of construction mach...
