Abstract

The invention discloses a fault monitoring early-warning system and method of a shield machine. The system comprises a host monitor, a shield machine condition detector for monitoring condition information of a monitored shield machine in real time, an early warning prompt device controlled by the host monitor, and a timing circuit connected with the host monitor; the early warning prompt device is connected with the host monitor; and the shield machine condition detector comprises a main bearing condition detection unit which monitors the condition of a main bearing of the shield machine in real time, a cutterhead detection unit which monitors the condition of a cutterhead of the shield machine in real time, and a cutterhead driving detection unit for monitoring the condition of a cutterhead driving system in real time. The method comprises the steps that 1) the condition of the shield machine is monitored, and monitoring information is uploaded synchronously; and 2) condition information of the shield machine is analyzed and processed. Thus, a fault in the shield machine can be monitored timely and accurately, and early warning prompt can be provided according to a monitoring result.

Description

technical field [0001] The invention belongs to the technical field of shield machine fault monitoring, and in particular relates to a shield machine fault monitoring and early warning system and method. Background technique [0002] The shield machine is a high-value-added complex equipment integrating advanced technologies such as machinery, electricity, hydraulic pressure, optics, network, automatic control, sensing, and information. And other functions, and tailor-made design and manufacture according to different geological conditions, the reliability requirements are extremely high. The status of core components such as the main bearing of the cutter head, the main drive reducer, the screw reducer, and the hydraulic system directly affect the construction period, safety, cost, and quality of the shield tunneling. Due to factors such as high mobility of personnel in construction units, uneven personnel levels, and complex construction environments, shield machines have...
