| 盾构刀具磨损检测一直是盾构施工过程中的一个难题。在盾构机掘进过程中，无法直接测量刀具的磨损量，这就给刀具的视情换刀带来了巨大的困难。针对盾构施工时的刀具磨损检测，设计了盾构滚刀磨损在线检测系统。其中，下位机采用电涡流传感器对盾构滚刀的磨损进行检测，将电涡流传感器采集到的电信号转换为数字信号后通过串行通信方式与上位机通信；上位机利用C#编程语言开发了盾构滚刀磨损检测软件系统，将下位机采集到的信号进行处理与计算并显示出刀具的磨损量。通过对盾构滚刀磨损的实时测量，从而及时准确地掌握滚刀的磨损状态，为“视情换刀”提供技术支持。 |
| 英文摘要: |
| Cutter tool wear detection is always a difficult problem in shield tunnel construction. During tunneling process, the wear cannot be measured directly, which has brought great difficulties to the timely cutter tool replacement. Aimed at the problems of cutter tool wear detection during shield machine construction, an on line system of cutter tool wear detection is designed. The subordinate computer measures the cutter wear by electricity eddy current sensor, and transforms the collected electricity signal into digital signal, and then it communicates with the upper computer by the serial communication. The upper computer program of cutting tool wear detection is developed by C#. And the collected signals are processed and showed by the software system. By measuring the cutter wear at current time, we can know the state of cutter wear timely and accurately. The system can offer the technology support for replacing cutter tool by condition. |
