Aiming at the questions existed in the simulating test of shield tunnelling machine, a condition monitoring system of simulator test rig for shield tunnelling machine was designed using common configuration software “Kingview”, and the structure characteristics of hardware and software were also analyzed. The human machine interface of condition monitoring system was developed and designed, and the design idea was also expounded in detail. The experimental results show that the designed condition monitoring system has good operation performance and high security, which has been applied in the simulator tunnelling successfully.
