Abstract

The invention discloses a control system for automatically adjusting the posture of a shield tunneling machine in the technical field of automatic control. The control system comprises an upper computer, a lower computer, a shield tunneling machine posture measuring system, a shield tunneling machine propelling system and a feedback sensor, the upper computer and the lower computer communicate with each other through Ethernet, the shield tunneling machine posture measuring system is in one-way communication with the lower computer through the Ethernet, and the feedback sensor is in one-way communication with the lower computer through CCLING. According to the control system for automatically adjusting the posture of the shield tunneling machine, through algorithm automatic calculation control, the deviation degree and the deflection angle of a rear shield body of the shield tunneling machine and a plan line are obtained, and the current attitude of the shield tunneling machine is quantified according to a unified standard. The pressure of an oil cylinder in each subarea of the propelling system is adjusted by combining the real-time change condition of the posture of the shield tunneling machine, so that the posture of the shield tunneling machine can be adjusted more stably and efficiently, the construction quality of the shield tunneling machine is improved, the construction risk is reduced, and the intelligent level of the shield tunneling machine construction industry is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a control system for automatically adjusting the attitude of a shield machine. Background technique [0002] With the increasing number of underground rail transit and various tunnel projects, the demand for shield machines in current infrastructure projects is also increasing. However, shield machines will also face more complex construction environments and accident risk sources during the construction of underground tunnels. . [0003] During the tunneling construction process of the shield machine, the posture of the shield is related to the safety and quality of the tunnel construction, and is an important reference index for the tunneling process. At present, the attitude control of the shield still relies on the construction experience of the shield driver, and manually adjusts the thrust of the propulsion cylinders in each zone according to the situation of the...
