The test-bed of the shield control system is rebuilt and the PLC control system is re-designed,so as to develop large-diameter slurry shields by ourselves.The hardware configuration of the test-bed is presented in detail,the optimized control program is analyzed,and the communication between Schneider PLC and the frequency converter and that between Schneider PLC and distributed I/O are set up by means of Profibus-mastering mode.The design and realization of the frequency-converting drive system the cutterhead,the thrust system and the slurry supply system are studied with emphasis.The test demonstrates that the control system is reliable and efficient.
