[0027] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment includes: a motor 4, a fixing pin 5, a PLC module 6, a power supply module 7, a signal filter 8, a control handle 9, a control circuit 10, a power supply circuit 11, a power filter 12, a flip plate frame and a flip plate.

[0030] The control handle 9 is connected to the PLC module 6 through the control line 10, and the signal filter 8 is arranged on the control line 10. The PLC module 6 is connected to the power supply module 7, and the power supply module 7 is connected to the motor 4 and the fixed pin 5 through the power supply line 11. The motor 4 is installed on the flip plate frame, the motor 4 is connected to the flip plate and drives the flip plate to rotate, and the fixed pin 5 is installed on the flip plate frame and is used to limit the flipping of the flip plate. At the same time, the power supply module 7 is connected to the power filter 12 and is powered by the power filter 12.

[0031] In one embodiment, in order to avoid any electromagnetic interference in the darkroom, the motor 4, the fixing pin 5, the PLC module 6, the power supply module 7 and the flip plate are arranged inside the darkroom, and the signal filter 8, the control handle 9 and the power supply filter 12 are arranged outside the darkroom.

[0032] like Figure 3As shown, the flip plate includes: an absorbing material 13, a ferrite 14 and a reflective steel plate 15; the reflective steel plate 15 is arranged on one side of the flip plate, and the ferrite 14 and the absorbing material 13 are arranged on the other side of the flip plate. A motor 4 is connected to the middle of one side of the flip plate, and a fixing pin 5 is installed on the side adjacent to the side where the motor 4 is installed on the flip plate. The fixing pin 5 is allowed to extend or retract, thereby fixing or releasing the flip plate.

[0033] like Figure 2 As shown, the flip plate is driven by the motor 4 to flip around the rotation axis, and the two ends of the flip plate along the rotation axis are supported by the first support structure 1 and flip relative to the flip plate frame. The flip plate frame is on the shielding steel plate on the floor of the darkroom through the second support structure 2 and the third support structure 3. The first support structure 1 is supported on the shielding steel plate on the floor of the darkroom, and a shielding metal mesh is installed at the first support structure 1 on the shielding steel plate on the floor of the darkroom.

[0034] In a preferred embodiment, the flip plate frame is supported at the elevation of the shielding steel plate on the floor of the darkroom by the second supporting structure 2 and the third supporting structure 3, which are at different elevations from the first supporting structure 1, so that mutual influence can be avoided during rotation.

[0035] Example 2

[0036] Example 2 is a preferred example of Example 1.

[0037] like Figure 1-3 As shown, this embodiment includes: a first supporting structure 1, a second supporting structure 2, a third supporting structure 3, a motor 4, a fixing pin 5, a PLC module 6, a power supply module 7, a signal filter 8, a control handle 9, a control circuit 10, a power supply circuit 11, a power supply filter 12, an absorbing material 13, a ferrite 14 and a reflective steel plate 15.

[0038] The first support structure 1 is installed above the shielding steel plate at the bottom of the lowest foundation pit of the darkroom, fixed to the cement structure with chemical screws, and equipped with a shielding metal mesh. The second support structure 2 and the third support structure 3 are fixed to the cement structure with chemical screws at the shielding steel plate elevation of the darkroom floor, and equipped with a shielding metal mesh. The first support structure 1 is mainly used to bear the X direction ( Figure 1 The second supporting structure 2 and the third supporting structure 3 are used to bear the weight of the flip plate frame.

[0039] The main function of the motor 4 is to provide power, flip the absorbing material 13 and ferrite 14 installed above 360 ​​degrees, and place different absorbing materials 13 and ferrite 14 or reflective steel plates 15 on the surface to complete the conversion of different test requirements.

[0040] The fixed pin 5 will choose to retract or extend during the switching process to fix the entire structure of the absorbing material 13, ferrite 14 and reflective steel plate 15. The absorbing material 13 and ferrite 14 are used to reduce the reflection of the electromagnetic waves emitted by the antenna from the ground during the RS test (radiated immunity test), or to absorb the electromagnetic waves emitted by the transmitting antenna toward the ground. The reflective steel plate 15 exists on the opposite side of the absorbing material 13 and the ferrite 14, and is used to ensure the continuity of the reflective steel plate in the entire darkroom after switching, so as to ensure the integrity of the RE test (radiated emission test) environment.

[0041] The PLC module 6 receives different signals from the control handle 9 through the control line 10 and the signal filter 8, transmits the signal to the power supply module 7, and then supplies current in different directions to the motor 4 through the power supply line 11 to perform a flipping action to meet different test requirements.

[0042] The power filter 12 is a device for filtering and suppressing noise when the external power enters the shielding body, and is also the power source of the entire system. For example, when performing RE testing in the darkroom, the reflective steel plate 15 can be placed on the top surface by giving a signal through the control handle 9, or when performing RS testing in the darkroom, the absorbing material 13 and the ferrite 14 can be placed on the top surface by giving a signal through the control handle 9, which greatly improves the conversion efficiency between different tests.

[0043] After a signal is generated by operating the control handle 9, it is transmitted to the PLC module 6 via the control line 10 and the signal filter 8. The PLC module 6 will react under different working conditions according to the previously set logical principles and transmit the signal to the next-level power supply module 7.

[0044] When the signal in the PLC module 6 is transmitted to the power supply module 7, the "OR" circuit in the power supply module 7 will select work according to the signal given by the upper-level PLC module 6, including three working conditions: flipping, emergency stop, and cutting off the power supply circuit. The first two working conditions will transmit the operation signal or current energy to the motor 4 and the fixed pin 5.

[0045] More specifically, when the motor 4 and the fixed latch 5 receive two different working conditions in the power supply module 7, under the premise that the first support structure 1, the second support structure 2, and the third support structure 3 are stably supported, the motor 4 and the fixed latch 5 will perform different modes of operation to ensure that the conversion is completed accurately, safely and quickly; when a flip signal is received, the fixed latch 5 will retract to ensure the start of the flip, the motor 4 will start to rotate and the rotation angle will be 360°. After completing the flipping action, the fixed latch 5 will extend to the flip plate composed of the absorbing material 13, the ferrite 14 and the reflective steel plate 15 to ensure stability; when an emergency stop signal is received, the fixed latch 5 will keep retracting to ensure the smoothness of the flipping action, the motor 4 will stop rotating, and the flipping action will stop urgently.

[0046] When a signal to flip the control handle 9 is given, the fixed pin 5 will retract into the structure and will not hinder the work. The flip plate needle structure composed of the absorbing material 13, ferrite 14 and reflective steel plate 15 in the darkroom will perform a complete 360° flip. When an emergency stop signal is given to the control handle 9 during this process, the PLC module 6 will cut off the power supply to the motor 4 in the power supply module 7 and the fixed pin 5 will remain retracted, and the flipping work will stop. When the flipping work is completely completed and in place, a signal to cut off the power supply circuit is given to the control handle 9, and the power supply module 7 will cut off the power from the power filter 12 to ensure that there is no current in the entire power supply line 11, and no electromagnetic interference will occur in the darkroom.
