摘　　要：针对金刚石绳锯机的水下切割作业,设计了以PLC为执行控制器、上下位单片机为数据处理控制器的监测控制系统,能够实现自动和手动两种控制方式。设计了上、下位机硬件与软件系统,其中:下位机主要包括检测信号输入、信号隔离、漏水监测等电路,实现对水下锯绳张力、进给位移传感器信号的采集及漏水检测功能;数据传输采用RS-485总线标准,通过水密电缆将数字信号由水下传送至船上上位机系统;上位机接收下位机信号,既进行人机界面LCD显示,又对PLC发送控制指令,由PLC系统对水下电磁阀进行控制。最后,通过水下自动切割管道试验验证了监测与控制系统的性能达到了工程使用要求。According to the cutting work of diamond wire saw underwater, its monitoring and controlling system was designed by using PLC as performer and up-down singlechip as data processor, which can control it automatically or.manually. The hardware and software of up-down singlechip were designed. The down singlechip consists of signal input, signal separating and water leak electro circuit, which not only can collect the sensors signal on saw wire tension and advancing displacement, but also inspect water leak situation. Using waterproof cable to transfer data from underwater to up single slice computer on board, which bases on RS-485 bus standard. After receiving signal from the down single slice computer, the up single slice computer shows the data on interface and sends out control order to PLC, which controls the electromagnetism valve underwater. In the end, the performance test of this monitored control system was done by cutting pipeline underwater and it can satisfy with the engineering request.
