Shield/TBM online state monitoring system

Abstract

The invention belongs to the technical field of device state monitoring, and provides a shield / TBM online state monitoring system. The shield / TBM online state monitoring system comprises mechanical-signal collection apparatuses and an oil-liquid-parameter-signal collection apparatus; the multiple mechanical-signal collection apparatuses are pasted on a shield / TBM; signals collected by the multiple mechanical-signal collection apparatuses are fed into a data concentration center and processed through a data collection conversion module; the oil-liquid-parameter-signal collection apparatus comprises a hydraulic-oil-parameter-signal collection apparatus body and a lubricating-oil-parameter-signal collection apparatus body; signals collected by the hydraulic-oil-parameter-signal collection apparatus body and the lubricating-oil-parameter-signal collection apparatus body are directly fed into the data concentration center and processed; the shield / TBM online state monitoring system also comprises a data calling module; the data calling module is communicated with the data concentration center. According to the shield / TBM online state monitoring system, real-time monitoring of the device working state is achieved, and a technology guarantee is provided for safer and more reliable construction, and the information level of engineering management is improved.

Description

Technical field [0001] The invention belongs to the technical field of equipment condition monitoring, and specifically relates to a shield / TBM online condition monitoring system. Background technique [0002] Since the working environment and occasion of the shield / TBM is a closed space, the equipment operation failure cannot be intuitively judged. When the equipment fails, the maintenance is difficult, which affects the construction period and the cost is huge. Therefore, the shield / TBM is online and the shield / TBM is monitored in real time. TBM status is necessary for tunnel and underground construction. Shield / TBM existing equipment detection technology mainly includes two parts: oil detection and status monitoring, and both detection methods are performed offline, that is, through the handheld monitoring equipment, the status information of the running equipment is periodically performed Acquisition, analysis based on the collected data (or the data obtained by analyzing th...

Problems solved by technology

Off-line detection cannot reflect the true state and performance of the equipment in real time, the collected data is not continuous, and cannot reflect the complete condition of the equipment, and the collection and analysis of human intervention factors are relatively large, the collected samples are vulnerable to secondary pollution, and remote control cannot be realized. Occupies a large number of testing personnel and equipment, high cost and low efficiency, and some shields / TBMs have their own monitoring systems for a certain subsystem, but the amount of monitoring information is limited, not comprehensive enough, and data collection cannot be performed
