The PLC receives the first feedback signal, changes the movement speed and the movement distance, drives the probe to descend to the test point, and further, the lifting driving circuit 41 sends a second feedback signal to the PLC through the first positioning module.
Next, when the PLC receives the second feedback signal, the PLC transmits the rotation direction, the rotation speed, and the rotation angle of the rotating electrical machine 3 to the torque driving circuit 42 (as shown in fig. 4) through the second positioning module 432, the torque driving circuit drives the rotating electrical machine 3 to operate, the measuring head rotates to a second predetermined position, and the torque driving circuit 42 transmits a third feedback signal to the PLC through the second positioning module. The PLC receives the third feedback signal, changes the rotation speed and the rotation angle, controls the torque driving circuit to drive the probe to rotate for one turn, and the torque driving circuit 42 sends a fourth feedback signal to the PLC through the second positioning module 432.
And then, judging whether the test result is qualified or not, if the test result is unqualified, for example, the PLC receives a rising pulse, the PLC further controls the torque drive circuit to drive the rotating motor 3 to perform retesting. If the retest result is not qualified, the PLC controls an alarm (not shown) to give an alarm. In addition, if the PLC does not receive the signal within the preset time, the test result is qualified.
The PLC receives the fourth feedback signal, and the PLC transmits the movement direction, the operation speed, and the operation distance of the first and second positioning modules to the lift driving circuit 41, and transmits the rotation direction, the rotation speed, and the rotation angle of the rotating motor 3 to the torque driving circuit 42, so as to drive the lift motor 2 and the rotating motor 3 to ascend and rotate to the position before starting, and to feedback the signal to the PLC through the first and second positioning modules.
