Usages of non-excavator method, like shield machine method for metropolitan constructions is faster and has a lesser impact on traffic, furthermore, the shield machine method can reduce environmental pollution. Currently in Taiwan, there is rarely any case study of shield machine method, thus the related techniques, such as mechatronics system, die development, working parameter database, and etc are still in stagnate. Therefore, the incompletion knowledge of shield-machine characteristics, performance, and maintenance skill cause specialist training problems, construction schedule delay, and poor quality control, all these problems will increase contractor cost. This thesis presents a method to build the frame structure of graphic monitoring system by using graphic control software, the frame structure combines peripheral sensors, the digital compass positioning system, optics target system, CCD camera system, oil pressure system, and database system. The above sensors can instantaneously monitor the shield machine boring path and state. This thesis already completed a frame structure of digital compass positioning system, and the interface of mechatronic system has also been established. Furthermore, the simulation data shows that this research could achieve accuracy positioning requisition for construction. Each unit in this system could combine controller with related equipments as shield machine monitoring system.
