s2, in the first device, a detection probe (4) is located below an outer cylinder (21), meanwhile, an emitting end is perpendicular to a wall body, a servo motor (152) is started, at the moment, the servo motor (152) rotates forwards to drive a mounting groove (153) to rotate, a lead screw (22) is further driven to rotate, the lead screw (22) drives a scanning assembly (3) to move upwards through a nut pair (23) when rotating, when a sensor (28) is in contact with a second sensor (27) at the top, the servo motor (152) stops rotating and rotates backwards, the scanning assembly (3) moves downwards, when the sensor (28) is in contact with a first sensor (26) at the bottom, the servo motor (152) stops rotating and rotates forwards, and the scanning assembly works in a reciprocating and circulating mode;

s3, when the scanning assembly (3) rises, starting a rotary cylinder (36), driving a driving shaft (35) of the rotary cylinder (36) to rotate, further driving a gear (34) to rotate, driving a gear ring (33) to rotate through rotation of the gear (34), driving a detection probe (4) to rotate through a rotating ring (32) while the gear ring (33) rotates, wherein the offset angle is 5 degrees when the detection probe (4) rotates, and when a sensor (28) is in contact with a first inductor (26) and a second inductor (27), respectively controlling the rotary cylinder (36) to rotate until the irradiation ray of a first device coincides with the start line of a second device;

s4, integrating and taking values of the first scanning plane and the second scanning plane of the equipment through the scanning imaging module in the main control computer (5), further performing data analysis and image comparison through the image processing module, and finally obtaining a sunken or protruded area which does not reach the verticality in the vertical surface of the wall body through the data calculation module.
