Problems solved by technology

[0004] Due to the soft characteristics of mining machinery operation roads and complex road conditions, it is difficult to identify
At present, in terms of road surface recognition, the main road surface is mainly recognized based on the road surface adhesion coefficient, and other parameters of the road surface are used for auxiliary recognition. Failure to consider the reliability of identification results and failure to make full use of identification data with insufficient reliability
This will seriously affect the reliability of road surface recognition, and it is also an underutilization of road surface recognition data

The invention discloses a composite soft pavement recognition system and recognition method. The pavement recognition system comprises a torque measurement module, an angular acceleration measurementmodule, a linear acceleration measurement module, a distance measurement module, a pressure measurement module, a gradient measurement module, a data fusion module, a pavement condition recognition module, a data storage module and a recognition result display module. The pavement recognition method comprises the following steps: acquiring mechanical equipment state information based on multiple sensors; carrying out composite pavement recognition based on main recognition of pavement adhesion coefficients, auxiliary recognition based on pavement fluctuation, auxiliary recognition based on tire slip rate and auxiliary recognition based on tire subsidence amount; calculating and outputting recognition confidence; identifying confidence reliability judgment; performing pavement grade matching based on the pavement adhesion coefficient; identifying the gradient of the pavement; and outputting the pavement recognition result. According to the method, a composite identification mechanism isadopted for soft pavements of engineering and mine operation sites, and accurate and reliable identification of pavement conditions is realized.

Description

technical field [0001] The invention belongs to the technical field of road surface recognition of mining machinery and equipment, and in particular relates to a compound type soft road surface recognition system and a recognition method. Background technique [0002] With the acceleration of my country's economic development and urban integration construction, the demand for mineral energy continues to increase. According to the "China Mineral Resources Report 2016-2018", China's iron ore resource consumption has exceeded 1.2 billion tons for three consecutive years, averaging Ranking first in the world, this puts forward higher requirements for the reliability and operating efficiency of mining machinery and equipment. [0003] In order to improve the reliability and operating efficiency of mining machinery and equipment, it is necessary to reliably and fully identify the operating environment. As an important part of it, road surface recognition directly affects the opera...
