Heavy hammer material level detection system and detection method based on image analysis

Abstract

The invention provides a heavy hammer material level detection system and detection method based on image analysis. The detection system comprises a control module, a camera, an information acquisition module, a wireless communication module, a user, a heavy hammer and a cable roller assembly; the heavy hammer is arranged in a material bin and connected with the control module through a motor, thecamera is located above the wall of the material bin and used for shooting images of the heavy hammer movement in the material bin, the images are sent to the control module through the information acquisition module, the control module performs computing processing on received image frames, and after a material level value is obtained, the material level value is transmitted to the user throughthe wireless communication module. The heavy hammer material level detection system and detection method based on the image analysis have the advantages that the integration level is high, control components are few, the cost is low, the work is reliable, the use and maintenance are easy, the disadvantage that a traditional heavy hammer material level measuring device has high maintenance cost isovercome, the disadvantage that an ultrasonic material level measuring device is sensitive to dust is overcome, the self-maintenance of the device can be achieved, therefore, the heavy hammer materiallevel detection system and detection method based on image analysis have a wide application prospect in power plants, chemical engineering and other process control industries.

Description

technical field [0001] The invention relates to a heavy hammer material level detection system and detection method based on image analysis, belonging to the technical field of machine vision. Background technique [0002] Material level is a very important process parameter in process automation production. There are many methods for continuous monitoring of material level, common ones are radar level gauge, ultrasonic level gauge, hammer level gauge, etc. Among them, the heavy hammer level gauge is a kind of mechanical contact detection instrument that was applied earlier. It is not affected by dust, water vapor, temperature, silo structure, material properties and other factors in the application of material level measurement. It is widely used in continuous measurement of distance material level. [0003] However, due to the complex mechanical structure of the traditional heavy hammer material level detection, there are maintenance problems of stability and reliability...
