In one embodiment of the invention, the length of the exposed portion is not less than the thickness of the shield slot 628.

In a fifth specific application scenario of the present invention, the control module is an upper computer disposed outside the dark room; when an electromagnetic compatibility test is required, an experimenter inputs an antenna to be used into the upper computer, (in this embodiment, to facilitate description until two antennas are used), the upper computer controls a fifth antenna 623 matched with an antenna accommodating cavity 620 to move to a preset position on a shielding panel 622 according to content input by the experimenter, after the fifth antenna 623 moves in place, the upper computer controls a driving motor 629 to rotate, thereby driving the shielding panel 622 to ascend, in the ascending process, a signal cable between the fourth winding device and the radio frequency switch is gradually stretched, after the shielding panel 622 ascends to a first preset station, the signal cable between the fourth winding device and the radio frequency switch slides into a shielding groove 628 formed on a shielding table 625, and exposed parts on the signal cable are contacted with beryllium copper reeds arranged at two sides of the shielding groove 628, namely, a shielding layer of the signal cable is contacted with the beryllium copper reeds arranged at two sides of the shielding groove 628, so that continuous conductors are formed, and shielding performance of the shielding room is ensured;

meanwhile, after the shielding panel 622 rises to the fourth preset station, the beryllium copper reeds arranged on the periphery of the shielding table 625 are contacted with the beryllium copper reeds arranged in the first notch 500 of the shielding chamber, so that the electric continuity of the ground of the shielding chamber is ensured; meanwhile, the limiting device on the screw rod fixing seat 631 detects that the distance between the epitaxial fixing plate 626 of the shielding panel 622 and the limiting device is smaller than a preset value, the limiting device sends an in-place signal to the upper computer, and the upper computer controls the driving motor 629 to stop rotating after receiving the in-place signal; at this time, the experimenter inputs the antenna position information to the upper computer according to the test requirement, the upper computer controls the fifth antenna 623 to move to a proper position in the shielding chamber according to the input antenna position information, and simultaneously, the upper computer controls the wire coiling device to pay out or take up at a matched speed according to the moving direction and the moving speed of the fifth antenna 623, so that the relative position between the exposed part of the signal cable and the shielding groove 628 is kept unchanged, and the shielding performance of the shielding chamber is ensured not to be damaged;

When the test is completed and the antenna needs to be replaced, an experimenter inputs an antenna replacement signal to the upper computer, and after the upper computer receives the antenna replacement signal, the upper computer controls the fifth antenna 623 in the shielding chamber to return to a preset position on the shielding panel 622 again, synchronously controls the fourth wire coiling device to pay out or take up wires at a matched speed, and controls the driving motor 629 to rotate after the fifth antenna 623 is in place, so as to drive the shielding panel 622 to descend; when the shielding panel 622 is completely lowered, the upper computer controls the fifth antenna 623 on the shielding panel 622 to leave the shielding panel 622, controls the sixth antenna 624 matched with the replacement antenna signal to move to a preset position on the shielding panel 622, and controls the driving motor 629 to drive the shielding panel 622 to rise, so that the sixth antenna 624 enters the shielding room, and the test is started again.

It will be appreciated that, because the stroke of the lifting device 621 is fixed, when the shielding panel 622 is lifted to the fourth preset station, the distance between the winding device and the radio frequency switch is fixed, so that an experimenter can strip the insulation layer of the signal cable at a suitable position of the signal cable between the winding device and the radio frequency switch according to the actually measured distance, so as to form an exposed part of the signal cable, thereby enabling the shielding layer of the signal cable to contact with beryllium copper reeds arranged at two sides of the shielding groove 628 when the shielding panel 622 is lifted to the fourth preset station, thereby forming a continuous conductor and guaranteeing the shielding performance of the shielding chamber.

It should be noted that, in the actual process of the detection experiment in the shielding room, the staff can freely combine the 2 types of detection table replacing modes and the 3 types of antenna replacing modes proposed above.

It is apparent that the above examples are only examples for the purpose of more clearly expressing the technical solution of the present invention, and are not limiting the embodiments of the present invention. It will be apparent to those skilled in the art from this disclosure that various other changes and modifications can be made herein without departing from the spirit and scope of the invention. The scope of the invention is therefore intended to be covered by the appended claims.
