针对盾构施工过程中HBW、EP2和盾尾密封油脂消耗量大、成本高，且现有测量装置具有稳定性差、精度低等问题，开发了盾构油脂智能监测系统。首先，采用相位激光传感器测量油桶高度变化，根据高度差和标准桶质量计算油脂用量; 然后,通过OPC协议读取盾构状态，统计单位环内各类油脂用量并保存到数据库中；最后，基于盾构/TBM大数据中心实现现场数据的远程获取与存储。该系统在工程现场进行了试验与应用，达到了较好的应用效果： 1）测量效率高，测量装置可实现对油脂桶余量的连续实时测量，测量数据可以本地存储和远程读取； 2）测量精度高，误差可以控制在0.01 kg/环以内； 3）实时测量结果可辅助判断盾构运行状态，同时也便于成本分析及控制； 4）系统接入盾构/TBM大数据平台，便于场内外人员实时掌握施工状况。

 In order to solve the problems of large consumption and high cost of HBW, EP2 and shield tail sealing grease during shield boring process, and the poor stability and low accuracy of the existing measuring devices, an intelligent monitoring system for shield grease is developed. The phase laser sensor is used to measure the height change of oil drum, and calculate the amount of grease according to the height difference and the weight of standard drum. Then, the state of shield machine is read through OPC protocol, and the consumption of various kinds of grease in the unit ring is counted and saved in database. Finally, the remote acquisition and storage of field data is realized based on the shield machine/TBM big data center. The system has been tested and applied at engineering site, and achieved good application results: (1) With high measurement efficiency, the measuring device can realize continuous realtime measurement of the oil tank balance, and the measurement data can be stored locally and read remotely; (2) With high measurement accuracy, the error can be controlled within 0.01 kg/ring; (3) The realtime measurement results can assist in judging the operating status of shield machine, and also facilitate cost analysis and control; (4) The system is connected shield machine/TBM big data platform, which is convenient for personnel inside and outside the site to grasp the construction status in real time.
