Tunnel boring machine attitude measuring system and measuring method of same

Abstract

The invention discloses a tunnel boring machine attitude measuring system and a measuring method of the same, belongs to location measurement devices and measurement methods, and solves the problems of hysteretic nature of measurement of a prism guidance system, drifting of a gyroscope guidance system, limit on horizontal yaw angle measuring range and easily shielded intervisibility space in a laser target guidance system. The measurement system provided by the invention comprises an attitude angle measuring unit, a travel displacement measuring unit and a master control computer, wherein the attitude angle measuring unit and the travel displacement measuring unit are respectively in communication connection with the master control computer in a wired or wireless form. The measuring method provided by the invention acquires attitude data of a tunnel boring machine in a tunneling state, obtains information of three angles of the tunnel boring machine by mutually compensatory amendment of a gyroscope and an inclinometer, and simultaneously measures the tunneling position and distance of the tunnel boring machine by a second accelerometer and a travel displacement sensor. With the tunnel boring machine attitude measuring system and the measuring method of the same, the problems of the existing technology are solved, and the accuracy and the stability of measurement are improved.

Description
