System and method of management and control of quasi-rectangular shield construction

Abstract

The present invention relates to a system and method of management and control of quasi-rectangular shield construction. The system comprises: a shield data acquisition device arranged in a tunnel and configured to collect the construction data in the process of shield tunneling machine construction; a plug-in subsystem configured to monitor the shield construction date in the tunnel in real time; a data exchange processor arranged in the tunnel configured to connect the data acquisition device and the plug-in subsystem through an exchange and transmit the construction data monitored by the plug-in subsystem to the data acquisition device; a data management center arranged on the ground and configured to connect the data exchange processor through the exchange to receive and display the construction data transmitted by the data exchange processor; a shield control PLC arranged in the tunnel and configured to control the shield tunneling machine which is connected with the data exchange processor through a bus. According to the invention, the safety and the reliability of an original control system of a shield tunneling machine are effectively ensured.

Description

technical field [0001] The invention relates to the field of shield tunneling, in particular to a management and control system and method for rectangular shield tunneling. Background technique [0002] With the large-scale development of urban underground space, the shield method construction technology is more and more used because of its small impact on the above-ground and underground structures and the surrounding environment, ensuring traffic flow, reducing road interruptions, and pipeline relocation. Construction of urban roads, underground common trenches, and subway tunnels. With the expansion of the domestic underground space construction market, more and more shield machines from different manufacturers are widely used, and the corresponding risk management and control pressure increases after the shield machine is launched, which can easily lead to shield tunneling. risks in the process. [0003] The existing risk management system in the construction process o...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of the prior art, provide a management and control system and method for similar rectangular shield construction, and solve the problem that the communication mode of the existing risk management system has a large security risk and is easily attacked and affects the shield. Construction safety, and the risk management system will also affect the processing speed of the shield machine control PLC and thus affect the shield construction
