Tool state monitoring and life predicting system based on multi-source information fusion

Abstract

The invention discloses a tool state monitoring and life predicting system based on multi-source information fusion, comprising: an information acquisition module, a signal preprocessing module, a state monitoring module, a life predicting module, and a remote monitoring module. The information acquisition module collects the parameter information of the hob, and sending them to the condition monitoring module and / or the life predicting module after preprocessing by the signal preprocessing module; outputting the hob status by the condition monitoring module; outputting the remaining life of the hob by the life prediction module. The output of the status monitoring module and the life predicting module can be directly viewed on the spot and can be viewed remotely. The tool state monitoringand life predicting system based on multi-source information fusion realizes visual management by real-time monitoring the key parameters such as the force, wear amount, rotation speed, and shape ofthe hob by the hob monitoring device, and monitors the state of the hob in real time and predicts the remaining life of the hob by analyzing and processing the relevant signals of the hob. Further, the communication-related project management staff of the remote monitoring module can view through mobile phones, remote PCs, etc, helping humanely determine if the tool is replaced.

Description

technical field [0001] The invention belongs to the technical field of tool monitoring, and in particular relates to a tool state monitoring and life prediction system based on multi-source information fusion. Background technique [0002] At present, during the construction of the full-face tunnel boring machine, the inspection of the cutter head tool must first be stopped, and the tool wear cannot be observed during the excavation process, which seriously affects the progress of the project. The cutter head area is an unsupported area, and the soil warehouse is a closed high-pressure environment, which requires high quality maintenance personnel. The tool change process is time-consuming and laborious, and is prone to safety accidents. As far as the equipment itself is concerned, the cutter can only be repaired or replaced after it is damaged.

Problems solved by technology

[0002] At present, during the construction process of the full-face tunnel boring machine, the inspection of the cutterhead tool must be stopped first, and the tool wear cannot be observed during the excavation process, which seriously affects the progress of the project.

The cutter head area is an unsupported area, and the soil warehouse is a closed high-pressure environment, which requires high quality maintenance personnel. The process of changing the tool is time-consuming and laborious, and is prone to safety accidents

As far as the equipment itself is concerned, the cutter can only be repaired or replaced after it is damaged. The construction personnel cannot know the working status of the hob during the excavation process. Only when the cutter is seriously damaged and the progress of the excavation is greatly affected, the work of checking and changing the cutter is carried out. , affecting construction efficiency and construction economy

At present, relevant enterprises at home and abroad have carried out hob monitoring research, but it is still in its infancy, but the utilization rate of information is low, and it is impossible to predict the remaining life of the hob in advance
