Abstract

The invention discloses a rubber expansion joint space attitude detection device and method. The device comprises a stay wire type sensor module, which comprises three stay wire type sensors, whereinthe installation block ends of the three stay wire type sensors are fixed on a first flange plate at the other side of a rubber expansion joint, and the wire ends of the three pull wire type sensors are fixed at the same fixed point of a second flange plate on one side of the rubber expansion joint; a PSD photoelectric position sensor module, which comprises two PSD photoelectric position sensorsand two solid lasers, wherein the two PSD photoelectric position sensors are fixed to the first flange plate on one side of the rubber expansion joint, the two solid lasers are fixed to the second flange plate on the other side of the rubber expansion joint, and laser emitted by the two solid lasers irradiates the four quadrants of the two PSD photoelectric position sensors respectively; and a signal receiving and processing module, which is used for receiving voltage signals generated by the stay wire type sensors and the PSD photoelectric sensors and obtaining the spatial attitude of the rubber expansion joint through calculation.

Description

technical field [0001] The invention relates to the field of attitude detection of space objects, in particular to a space attitude detection device and method for rubber expansion joints. Background technique [0002] The 6D spatial attitude estimation of a rigid body in a three-dimensional space refers to estimating the 6D spatial attitude of a rigid body in a space coordinate system. The movement of a rigid body in three-dimensional space has six degrees of freedom, that is, three displacement degrees of freedom and three rotation degrees of freedom, so the detection of the spatial attitude of a rigid body can be transformed into the detection of the movement of a rigid body in six degrees of freedom. The rubber expansion joint used in nuclear power plants is composed of a mountain-shaped rubber pipe and a metal flange plate on both sides. In actual use, when the liquid in the pipe flows through, pressure will be generated, which may cause axial compression or stretching ...
