Embodiment 1

[0087] In this embodiment, an asphalt mixture mixing process monitoring system is disclosed, such as figure 1 As shown, it includes a data acquisition module, and also includes a mixing quality judgment module;

[0088] In this embodiment, in order to overcome the problems existing in the prior art that the mixing quality of each plate of asphalt mixture and the operating and screening status of the mixing equipment cannot be monitored and analyzed in real time, and the types of asphalt mixtures of different surface layers produced in real time cannot be automatically identified. and defects, to provide an asphalt mixture mixing process monitoring system, which adopts a non-intrusive method and uses a multi-modal information fusion strategy to evaluate the mixing quality of each plate in real time.

[0089] The data acquisition module is used to obtain the mixing data of each plate of mixture on the asphalt mixing equipment, and the mixing data includes aggregate weight data, ...

Embodiment 2

[0164] A method for monitoring an asphalt mixture mixing process, which is performed according to the following steps:

[0165] Step 1. Obtain the mixing data of each plate of the mixture on the asphalt mixing equipment, and the mixing data includes aggregate weight data, powder weight data, asphalt weight data, gradation data and asphalt mixing temperature data;

[0166] Optionally, step 1 is performed according to the following steps:

[0167] Step 1.1, collect the images of the asphalt mixing equipment when mixing each plate of mixture, and obtain the data image of each plate of mixture;

[0168] In step 1.2, the data image of each plate of mixing material is sequentially marked with the region of interest of the main component character data, character data segmentation and character data recognition to obtain the mixing data of each plate of mixing material.

[0169] In this embodiment, as Figure 5 As shown, obtaining the mixing data of each plate of mixture on the asp...

Abstract

The invention discloses an asphalt mixture mixing and process monitoring system and method. With a non-intrusive method, principal component data of an asphalt mixture are extracted in real time by using a template matching identification technology and a method for evaluating the mixing quality of the asphalt mixture by using a multi-modal information fusion strategy with a mixing ratio parameter, a grading parameter, a mixing temperature, and mixing time and the like is put forward; according to the prior knowledge of the asphalt mixture type, the type of the asphalt mixture produced in realtime is identified automatically without manual intervention; and a model distribution of aggregate data is established. The operation and sieving status of the mixing equipment is determined by combining the mixing time, so that the cross-time query and cost evaluation of historical data of the asphalt mixture as well as the early warning of the poor quality of the mixture or the fault of the mixing equipment are realized.

Description

technical field [0001] The invention relates to industrial testing equipment, in particular to an asphalt mixture mixing process monitoring system and method. Background technique [0002] As one of the important construction equipment for high-grade highway construction, the asphalt mixing equipment produced directly determines the quality of the road construction, thus affecting road diseases such as pavement rutting and cracks. The analysis and monitoring of material mixing quality and the operation status of mixing equipment is an urgent problem to be solved. The construction of each section of road includes several asphalt mixture mixing equipment, which are generally installed in remote areas far away from urban areas, and the mixing ratio and grading parameters of asphalt mixtures of different types and specifications produced on different pavements are determined by engineering test personnel. It is delivered to the mixing equipment operator in advance, and the pre-...
