摘　　要：以海瑞克盾构机为例,设计了泥水循环从站控制系统,使其与盾构机控制系统无缝连接,并独立于主站控制系统。各泥浆泵控制柜、阀门控制箱、地面监控站为从站结构,选用S7-200PLC控制,通过Profibus-DP现场总线与主站通讯;地面监控站采用S7-200PLC+Profibus-DP模块+计算机终端,同步显示远程控制站的泵、阀运行状态;泥浆泵驱动电机选用交流电机,调速控制采用schnielder Altivar71变频器+Profibus-DP通讯卡+S7-200PLC;采用Profibus-DP网络和西门子S7系列PLC搭建整个系统,总线采用2芯5类电缆作为传输介质,通讯速度可达12MBP;在本地控制柜增加光电隔离中继放大器,解决长距离盾构隧道掘进通讯信号传输衰减及隧道内用电安全等问题。Taking the Herrenknecht shield machine as an example, a slave station control system for slurry circulation, independent from the master station control system, is designed to seamlessly connect to the shield machine control system. The slave station is composed of slurry pump control cabinet, valve control box and ground monitoring station. The S7- 200PLC is selected for the control and the Profibus-DP is used for communication with the master station. In ground monitoring station, a combination of S7-200PLC＋Profibus-DP modulus＋computer terminal is designed to synchronously display the operation conditions of pumps and valves. The slurry pump is driven by AC motor, with its speed controlled by a schnielder Altivar 71 frequency convertor, a Profibus-DP communication card and a S7-200PLC. The Profibus-DP network and Siemens S7 series PLC are utilized to construct the overall system with twin-core CAT 5 cable as the transmission media in the bus, with the transmission speed up to 12 MBP. Optoelectronic isolation relay amplifiers are added in every local control cabinet, which can solve the problems in long-distance shield tunneling communication signal transmission attenuation and electrical safety in the tunnel. （3 Figures, 2 References）
