Embodiment 1

[0036] Embodiment 1: A kind of TBM key parameter intelligent control method, such as figure 1 shown, including the following steps:

[0037] S1, the PLC reads the data of the upper computer and establishes the unique identification ID of the upper computer;

[0038] PLC is connected with several host computers, and each host computer has at least one hard disk, and each hard disk has its own hard disk serial number X, PLC reads a hard disk serial number X of the host computer, and then uses MD5 The encryption algorithm processes the hard disk serial number X to obtain the machine code Y, and then intercepts the last N digits of the machine code Y as the unique identification ID of the host computer. In this embodiment, N=12; different hard disks have different hard disk serial numbers No. X, so the unique identification ID of each host computer is different.

[0039] The upper computer is equipped with dual network cards, one network card is used to communicate with the PLC,...

Embodiment 2

[0078] Embodiment 2: A TBM key parameter intelligent control system, including PLC, host computer, edge computing station and cloud computing platform, PLC is used as the execution unit, the host computer and PLC are connected, relevant parameters can be set through the host computer, and through PLC adjustment, the PLC collects relevant excavation data through the sensor on the shield machine and sends it to the host computer; the edge computing station stores the risk alarm model of the shield jamming machine, the risk alarm model of the cutterhead jamming machine, the rock mass perception model and the auxiliary driving model, the edge computing station is connected with the host computer, and the edge computing station is used to process the data received by the host computer, and store the processed data synchronously in the big data center; the edge computing station calls relevant The model calculates the optimal value of TBM key parameters, and adjusts the key parameter...

Abstract

The invention discloses a TBM key parameter intelligent control system and method. The method comprises the following steps that a PLC reads data of an upper computer, and a unique identification ID of the upper computer is built; the PLC collects and sends tunneling data to the upper computer; shield machine equipment information is input, whether a shield machine normally tunnels or not is judged through the upper computer, and the upper computer sends the shield machine equipment information and tunneling data of normal tunneling to an edge computer station; the edge computer station process the tunneling data and the shield machine equipment information, and sends the tunneling data and the shield machine equipment information to a data center; the cutter rotating speed and advance speed are arranged through the upper computer, and the upper computer adjusts the tunneling data through the PLC; and a cloud computing platform retrains a shield machine model according to data of the data center, and the trained model is updated to the edge computer station. According to the TBM key parameter intelligent control system and method, closed-loop management of the data is realized.

Description

technical field [0001] The invention belongs to the technical field of tunnel intelligent construction, and in particular relates to an intelligent control system and method for TBM key parameters. Background technique [0002] TBM construction has the advantages of fast excavation speed, construction safety, and high-quality hole formation, and has been more and more widely used. At present, the selection of TBM excavation parameters still depends on human experience, and the level of drivers varies. They often cannot adjust the excavation strategy in a timely and effective manner, which has a great impact on the construction quality and efficiency, and may even cause casualties. Therefore, TBM intelligent tunneling technology has become a major technical challenge in the field of tunnel intelligent construction. [0003] A series of researches and explorations have been carried out on intelligent control in the field of tunnel intelligent construction at home and abroad, ...
