Problems solved by technology

[0004] Aiming at the problem that the existing visualization device cannot adapt to the harsh environment of the soil tank and the hob has poor visualization effect, the present invention proposes a real-time monitoring system and method for the hob load of the shield machine, which can monitor the hob load of the earth pressure balance shield machine in real time. Knife wear, which solves the problems that the existing visualization device has poor vision, cannot adapt to the harsh environment of high pressure, high humidity, and slag splashing in the shield machine, and cannot monitor the hob status in real time

Abstract

The invention discloses an earth pressure balance shield machine hob wear monitoring device and method based on image analysis. The hob cutter box assembly is opposite. The invention has the advantages of simple structure, convenient installation, clear field of vision, good protection effect and washing effect, and provides a stable and reliable structural basis for image analysis and processing. The on-line measurement of tool wear can be realized through the wear monitoring method, and at the same time through monitoring Video directly observes the hob status, which improves the safety, convenience, economy and reliability of hob wear monitoring.

Description

Technical field [0001] The present invention belongs to the technical field of earth pressure balanced shield structure, and specifically, the present invention relates to an image-based earth pressure balanced shield structure roller wear monitoring device and method. Background technique [0002] The tunnel shield construction is widely used in its safety, efficient, economic, and small environmental impact on the ground environment. The earth pressure balance shield structure is generally constructed in the soft soil or composite formation, especially in the composite formation, and the earth pressure balance shield structure is generally equipped with a hob and a scraper. With the shield machine, the wear of the hob It is inevitable. At present, the common monitoring means of roller wear has a odor additive method, sensor monitoring method, tracing parameter analysis method, rockfinder shape analysis method, and opening inspection. The odor additive method is suitable for app...
