[0052] The execution module comprises a base 3 arranged in the horizontal direction, a motor assembly 4 fixed on the base 3, a rotating assembly 5 connected to the output end of the motor assembly 4, and the second sensor is arranged on the rotating assembly 5. The first sensor is also arranged on the rotating assembly 5, and the first sensor is a first camera.

The memory metal net 5a is in the form of a sheet, the detection unit is a plurality of displacement sensors arranged on the memory metal net 5a, and the memory metal mechanism further comprises a heating unit for heating the memory metal net 5a. The execution module further comprises a second camera, which is used to monitor the reset condition of the memory metal net 5a and feed back the reset information of the memory metal net 5a to the control module.

[0054] The rotating assembly 5 is in a columnar shape, and the memory metal net 5a is parallel to the axis of the rotating assembly 5, and the gas outlet direction of the throttle plug 1 is arranged along the radial direction of the rotating assembly 5, so that the gas outlet of the throttle plug 1 can be vertically blown to the memory metal net 5a.

[0055] As shown in Figure 4 , the shaft sleeve assembly 2 is sleeved outside the rotating assembly 5, one end of the shaft sleeve assembly 2 is fixed on the base 3, and the shaft sleeve assembly 2 and the rotating assembly 5 are coaxially arranged by adjusting the distance between the shaft sleeve assembly 2 and the rotating assembly 5. In order to enable the shaft sleeve assembly 2 and the rotating assembly 5 to be coaxially arranged, the execution module further comprises a laser range finder 6. As shown in Figure 5 and Figure 6 , the laser range finder 6 is fixed on the rotating assembly 5, the straight line where the laser emission route of the laser range finder 6 is located intersects with the axis of the rotating assembly 5, the laser range finder 6 is used for measuring the distance between the shaft sleeve assembly 2 and the rotating assembly 5, and the laser range finder 6 feeds back the distance information measured to the control module.

[0056] In this embodiment, a plurality of throttle plugs 1 are arranged at equal intervals along the circumferential direction of the shaft sleeve assembly 2.

[0063] S1, operating the man-machine interaction module, inputting a command of detecting the gas outlet condition of the throttle plug 1 to the control module, at this time, the ventilation module does not work, and the gas outlet of the throttle plug 1 does not emit gas.

[0064] S2, the first sensor detects the position information of the throttle plug 1 to be detected, and inputs the position information of the throttle plug 1 to be detected into the control module, the control module controls the motor assembly 4 to drive the rotating assembly 5 to rotate, until the second sensor reaches the detection position, that is, until the memory metal net 5a is rotated to be perpendicular to the axis of the gas outlet hole of the throttle plug 1.

[0065] S3, the ventilation module ventilates the choke plug 1, the choke plug 1 discharges gas from the gas outlet, the second sensor detects the gas discharge information of the choke plug 1, the memory metal net 5a deforms, each displacement sensor detects the deformation amount and deformation position of the memory metal net 5a, and the deformation amount and deformation position information of the memory metal net 5a is input to the operation unit.

The second camera feeds back the reset information of the memory metal net 5a to the control module, and the control module judges whether the memory metal net 5a is reset to a sheet shape. If it has been restored to a sheet shape, the ventilation module stops ventilating the choke plug 1, and enters S4. If it has not been restored to a sheet shape, the memory metal net 5a continues to be heated until the memory metal net 5a is restored to a sheet shape, and then the ventilation module stops ventilating the choke plug 1, and enters S4.

[0066] S4, the control module feeds back the gas discharge information of the choke plug 1 to the man-machine interaction module, and the detection is completed.
