Abstract：Research purposes: develop PLC control system of EPB shield and master the key technology for localization of shield machine manufacture.
Research methods: The paper introduced the PLC control system of EPB shield machine on the respect of design, hard-ware configuration, control principle, programming language and type selection of PLC control system, esp. the control principle on earth pressure, stance of shield machine, progressing speed and thrust pressure. It introduced the basic requirements of computer control system on parameter configuration, fault diagnosis and remote monitoring and data collection of shield machine as well.
Research results: The design of PLC system was completed basically, which laid foundation for the localization of PLC system in Shield machine.
Research conclusions: Research and design on the Programmable Logic Controller (PLC) System in shield machine has been listed in the motional plan 863, which provided experimental references for domestically made PLC control system of shield machine.
