The invention discloses a device and method for detecting the roughness of the inner wall of a pipeline. A light source is disposed at one end of a pipeline to be detected, and a light intensity absorbing module and a signal processing module are arranged at the other end of the pipeline. When passing through the pipeline from one end of the pipeline, the light is bidirectionally reflected by thesurface of the inner wall of the pipeline due to the different roughness of the inner wall surface of the pipeline, thereby resulting in a change in the light intensity detected at the other end of the pipeline. The roughness of the inner wall surface of the pipeline can be determined according to the change of a light intensity value. The device and method can solve the problem in the prior art that the roughness of the inner wall surface of the pipeline cannot be measured, and the device is simple in structure and low in cost. 本发明公开了种检测管道内壁粗糙度的装置及方法，通过在待检测管道的端设置光源，在管道的另端设置光强吸收模块和信号处理模块，当光线从管道的端通过管道时，由于管道内壁表面存在粗糙度不样的
