Abstract:

A visualized realtime monitoring system for soil chamber of composite shield is established so as to monitor the working conditions of soil chamber and collect the rotation situations of cutterhead, wear conditions of cutter, image information of excavation strata and flow characteristics of soil. The working state of frontend equipment is monitored by monitoring system of upper computer, and the signal collected by camera is transmitted to video acquisition system in real time. The scheme of the visualized realtime monitoring system is introduced, the design of structure, hardware and software of the system are emphatically discussed, and the effectiveness of the system is verified by laboratory test and field test. The study results show that the visualized realtime monitoring system can realize the functions of realtime video monitoring, recording and playback of soil chamber and monitoring of temperature, humidity and pressure of the working system.
