Abstract: The overall performance and application of shield machine is directly affected by control system of shield machine. The control system of distributed network is a composite control mode, which puts the input and output signal scatter on the device and puts the operation focus into the control center. The on-site connecting of signal can fully reflects economic efficiency and practicality. It has advantages in the cost, service and assembly.The center of control is complete in information and exact in calculation. The distributed control system can meet the requirements of shield machine.

Key words: shield machine, PLC, control system, communication, network
