(16) A second filter 31, a bus controlling module 32, and a motor 33 are arranged in the cloud deck shielding case 3, and the camera mainboard 12 is connected with the input end of the second filter 31 through the power line and the control wire penetrating the cavity of the holder 2, the output end of the second filter 31 is connected to the bus controlling module 32; the bus controlling module 32 is connected to the motor 33. The motor 33 drives the camera shielding case 1, the holder 2 and the cloud deck shielding case 3 to move through a transmission structure.

(17) Specifically, the motor comprises a vertical motor 331 and/or a horizontal motor 332, and the bus controlling module 32 is connected with the vertical motor 331 and/or the horizontal motor 332; the horizontal motor 332 drives the cloud deck shielding case 3 and then drives the camera shielding case 1 and the holder 2 to rotate horizontally along a vertical axis through a first transmission structure; and the vertical motor 331 drives the holder 2 and then drives the camera shielding case 1 to perform a pitching motion through a second transmission structure.

(18) Furthermore, there are several mechanical limit switches connected between the bus controlling module 32 and the vertical motor 331 and the horizontal motor 332.

The camera mainboard 12 then transmits the processed audio and video signals to the optical fiber transceiver 13, which converts the audio and video signals into optical signals and transmits the optical signals to an external processing system via optical fiber. Similarly, an audio signal outside the test environment is converted into an optical signal through an outdoor optical fiber transceiver, and input into the camera shielding case 1, and then processed by the optical fiber transceiver 13 and the camera mainboard 12 in the camera shielding case 1, and then the audio signal is input to the speaker, which enables communication by telephone between the inside and outside of the test environment.

(27) Specifically, a monitoring opening of a front panel (front part of the camera) of the camera shielding case 1 is provided with a shielding glass.

(28) A second filter 31 is connected between the camera mainboard 12 in the camera shielding case 1 and the bus controlling module 32 in the cloud deck shielding case 3, and the second filter 31 is arranged in the cloud deck shielding case 3, and the control wire and the power line are led out by the camera mainboard and then connected to the second filter 31, and the second filter 31 is connected to the bus controlling module 32. The second filter 31 isolates the electromagnetic interference between the camera shielding case 1 and the cloud deck shielding case 3, so that the acquisition and transmission of audio and video signals in the camera shielding case 1 and control operations of the motor 33 in the cloud deck shielding case 3 can be normally performed and do not interfere with each other.

(29) Specifically, the second filter 31 includes a second feedthrough capacitor, a second cylinder, and a second shielding cover, composition and structure of the second filter 31 are basically the same as that of the first filter 14; the difference is the mounting manner: the first filter 14 is fastened to the inner side of the rear end cover 17 of the camera shielding shell 1 through one end of the first cylinder; and the second filter 31 is fastened to the intercommunicating pore of the cloud deck shielding case 3 and the holder 2 (such as the through hole 341 or 342 in FIG. 5) through one end of the second cylinder, the diameter of the second cylinder is larger than the diameter of the through hole 341 or 342, so that the through hole 341 or 342 can be completely covered; the second feedthrough capacitor is accommodated in the second cylinder, and the second shielding cover is mounted on the other end of the second cylinder, thereby isolating the second feedthrough capacitor in the second cylinder.

(30) It can be understood that, the power line and the control wire penetrating through the cavity of the holder pass through the intercommunicating pore where the cloud deck shielding case 3 and the holder 2 are communicated with each other and join up with the second feedthrough capacitor; the second cylinder is provided with a small hole for a lead of the second feedthrough capacitor passing through the small hole of the second cylinder and entering the cloud deck shielding case. Through the second filter, the power line and the control wire are processed by the second feedthrough capacitor before entering the cloud deck shielding case, which greatly reduces the radiation interference.

(31) Specifically, one end of the second cylinder is provided with a mounting hole, and is fastened by a nut to the intercommunicating pore where the inner side of the cloud deck shielding case and the hollow holder are communicated with each other, and covers the intercommunicating pore; the other end of the second cylinder is provided with a thread, and the second shielding cover is screw joint with the other end of the second cylinder.

(33) Specifically, the camera shielding shell 1 is mounted on the supporting seat 21, and the bottom of the camera shielding shell 1 is provided with an opening which is communicated with the nozzle 221 of the hollow tube 22; specifically, the central position of the supporting seat 21 is further provided with a mounting boss 211, the nozzle 221 passes through the mounting boss 211. The mounting boss 211 helps the camera shielding case 1 to be more closely connected to the supporting seat 21, which further prevents radiation leakage.

(34) FIG. 5 is a schematic structure diagram illustrating a cloud deck shielding case 3 according to an embodiment of the present disclosure. Specifically, as shown in FIG. 5, the cloud deck shielding case 3 is provided with a first groove 34, the left and right sides of the first groove 34 is provided with a left through hole 341 and a right through hole 342 respectively, the bottom of the first groove 34 is provided with a second groove 343, a front boss 344 and a rear boss 345, the bottom of the second groove 343 is provided with a worm 346, and the worm 346 is placed between the front boss 344 and the rear boss 345.

(35) FIG. 6 is a schematic connection diagram of a cloud deck and a holder according to an embodiment of the present disclosure. Specifically, as shown in FIG. 6, the hollow holder 2 is mounted in the first groove 34, and any one of the left through hole 341 and the right through hole 342 of the first groove 34 communicates with the annular hole 231 of the support ring 23.

(37) The vertical motor 331 drives the worm 346 to rotate, thereby driving the engaging teeth of the support ring 23 to rotate, so as to achieve the pitch of the holder 2. Since the camera shielding shell 1 is fixedly connected with the holder 2, the worm 346 can drive the support ring 23 to rotate around an axis which passes through the center of the support ring 23, which in turn drives the camera shielding case 1 to perform a front and back pitching motion; thereby the pitch of the camera shielding case 1 is achieved, which expands the shooting range.

(38) When the support ring 23 rotates around an axis which passes through the center of the support ring 23, the left and right sides of the support ring 23 are respectively in active contact with the left through hole 341 and the right through hole 342 of the first groove 34 and cover the through holes, the annular hole 231 of the support ring 23 is always communicated with the left through hole 341 and the right through hole 342 of the left and right sides of the first groove 34 separately.
