Software virtualization technology based material level detection method

Abstract

The invention relates to a software virtualization technology based material level detection method. The material level detection method comprises the steps of building an information acquisition platform, performing statistics on input and output conditions of materials, and recording working condition information of a detected object; building a loading model, modeling the materials by category, performing integral processing according to material flow data acquired in an earlier stage and inputting the modeled materials to the loading model; building a blanking model, and calculating a blanking accumulated value; building a material virtual detection model, wherein a virtual material level value displayed by the virtual material level in the module is formed by a difference value of real-time outputs of a loading module and a blanking module; and formulating a virtual material level automatic calibration module, performing analysis on an error, adjusting parameters and realizing closed-loop control. According to the method, the hardware investment cost can be greatly saved, a circumstance of material waiting is greatly improved, and a condition of material stacking caused by excessive material loading is completely eradicated, and the materials are supplied more smoothly; and the dust-exposed working time of workers is greatly reduced, occupational health conditions are improved, and production requirements are fully met.

Description

technical field [0001] The invention relates to a material level detection method, in particular to a material level detection method based on software virtual technology. Background technique [0002] At present, in metallurgical and chemical enterprises, physical level gauges are generally used for material level detection in the material supply process. Physical level gauges include the following types according to their uses and structural forms: rotary type level gauges, capacitive level gauges, Permanent magnet level gauge, ultrasonic level gauge, guided wave radar level gauge, laser level gauge, radio frequency admittance level gauge, hammer type level gauge, ray type level gauge and weighing type level gauge etc. The above-mentioned types of physical level gauges have their own advantages and disadvantages. For example, the resistance-rotary level gauge is more reliable in detection, but not durable; on the contrary, although the capacitive level gauge is durable, it...

Problems solved by technology

Feeding efficiency and accuracy cannot be guaranteed

It is difficult to guarantee the occupational health of workers, and the material deviation caused by manual feeding cannot be overcome

At the same time, due to the large number of system parameters and different error types, manual parameter adjustment requires a large workload and cumbersome operations.

[0004] The screenshot of the current material information displayed on the man-machine screen is as follows: image 3 As shown, the material level display range (unit: ton), it is necessary to manually convert the percentage of the remaining material level, which is not intuitive, and part of the material level gauge on the screen of the feeding system is damaged
