Abstract: The present invention provides a system and a method for measuring the inclination of a steel pipe multi-stage boring machine boom using a Bluetooth-based inertia measuring device sensor. Two or more inertia measuring device (IMU) sensor modules are attached to a boring machine boom when a tunnel is reinforced by a steel pipe multi-stage boring machine. So, the inclination of the boring machine boom is measured and transferred to a mobile tablet PC carried by a worker controlling the boring machine by Bluetooth-based short-distance wireless communications. So, the worker controlling the boring machine can perform boring work by checking the inclination of the boring machine boom in a driver′s seat of the boring machine. Also, an IMU sensor three-dimensionally provides the bi-directional inclination of a pitch and a roll which is not the uni-axial inclination and can accurately control a motion of the boring device boom. Also, the Bluetooth-based IMU sensor module is simply attached to and detached from the boring device boom. So, the system for measuring the inclination of a steel pipe multi-stage boring machine boom can easily perform the Bluetooth short-distance wireless communications for transmitting and receiving data including the measured inclination of the boring machine boom. Moreover, the system for measuring the inclination of a steel pipe multi-stage boring machine boom enables the user controlling the boring machine to confirm the inclination of the boring machine boom by using the mobile tablet PC. So, the system for measuring the inclination of a steel pipe multi-stage boring machine boom can reduce manufacturing costs of the steel pipe multi-stage boring machine boom.
