Shield tunneling machine cutter state monitoring system and method

Abstract

The invention discloses a shield tunneling machine cutter state monitoring system and method. The system comprises a data acquisition module, a control and transmission module and a data processing module, wherein the data acquisition module comprises a temperature sensor, an abrasion loss sensor and a rotation speed sensor; the temperature sensor is used for acquiring temperature information of acutter of a shielding tunneling machine; the abrasion loss sensor is used for acquiring abrasion loss information of a hob on the cutter; the rotation speed sensor is used for acquiring rotation speed information of the hob; the control and transmission module is used for controlling each of the temperature information, the abrasion loss information and the rotation speed information, and respectively transmitting the information to the data processing module through a plurality of wireless links; the data processing module is used for analyzing an operation state of the cutter of the shieldtunneling machine according to preset geological information, received tunneling parameter information, the temperature information, the abrasion loss information and the rotation speed information; and the abrasion loss sensor and the rotation speed sensor are magnetic sensors. According to the system and method, accident risk of shield tunneling construction can be reduced and the comprehensivebenefit of shield tunneling construction can be improved.

Description

technical field [0001] The invention relates to the detection field, in particular to a shield machine cutter head state monitoring system and method. Background technique [0002] Our country is currently at the peak of infrastructure construction. At present, 42 cities have approved the construction of subways, thousands of kilometers of subway tunnels are planned, and hundreds of kilometers of submarine, lake bottom, and river bottom tunnels are under planning. Due to the characteristics of fast construction speed, friendly construction environment, relatively safe construction, and little environmental disturbance, most of the newly planned tunnels will be constructed using the shield method. [0003] During the normal construction process, the earth ballast chamber and mud water chamber of the shield machine are ballasted, and the working status of the cutterhead and cutter is in a black box. Moreover, the working environment of the shield machine is complex, and vario...

Problems solved by technology

[0005] Tool wear detection is a key issue that affects the progress and economy of the tunnel project. At present, the tool wear mainly depends on the pressure change of the hydraulic system installed on the cutter head to detect individual points. It is impossible to realize the monitoring of tool wear and rotation status. Comprehensive analysis cannot be carried out on the construction status of the panel, which seriously affects the construction efficiency and construction planning
