[0033] Reference Figure 1-10 ,

[0034] A remote-controlled adaptive camera focus adjustment optimization control device comprises: a rotating base 1, a camera 2, a light-transmitting lens 11, a wiper 3 and a driving member 4. The camera 2 and the light-transmitting lens 11 are both mounted on the rotating base 1; the lens of the camera 2 is opposite to the light-transmitting lens 11; the driving member 4 is used to drive the rotating base 1 to rotate to a preset angle position and adjust to a preset horizontal position; the wiper 3 abuts against the light-transmitting lens 11, and the driving member 4 is also used to drive the wiper 3 to move on the light-transmitting lens 11. Specifically, a receiving chamber is formed on the rotating base 1, the camera 2 is arranged in the receiving chamber, and the receiving chamber is used to protect the camera 2.

[0035] By rotating the rotating base 1 to a preset angle, the camera 2 can be rotated to a suitable shooting angle and then take pictures. By driving the base to adjust to a preset horizontal position, the camera 2 can maintain a horizontal position during shooting, so that an image at a suitable angle can be taken horizontally, or the image at the suitable angle can be monitored. The light-transmitting chip is used to protect the lens of the camera 2 and prevent the lens of the camera 2 from being exposed to the outside. The wiper 3 moves on the light-transmitting chip to clean the light-transmitting chip and keep the surface of the light-transmitting chip clean to avoid the problem of poor shooting effect caused by stains on the light-transmitting chip.

[0036] Specifically, the pan / tilt head further includes: an angle encoder 41, and the angle encoder 41 is used to set the preset angle position.

[0037] Specifically, the gimbal further includes: an attitude gyroscope 42, and the attitude gyroscope 42 is used to set the preset horizontal position.

[0038] Specifically, the driving member 4 includes a support base 5 and a plurality of base adjustment motors 43, the support base 5 is rotatably connected to the rotating base 1; the plurality of base adjustment motors 43 and the support base 5 form a plurality of adjustment points that can be raised and lowered, so that the support base 5 and the rotating base 1 are adjusted to the preset horizontal position. Preferably, the base adjustment motor 43 adopts an electric push rod, and the base adjustment motor 43 is installed in the support base 5. The setting of the plurality of base adjustment motors 43 can quickly adjust the rotating base 1 to the preset horizontal position.

[0039] Specifically, the driving member 4 includes: a turntable motor 44, a belt transmission structure 45 and an insertion rod 46. The belt transmission structure 45 is composed of a pulley and a transmission belt. The insertion rod 46 is fixed to the support base 5, and a slot for inserting the insertion rod 46 is formed on the rotating base; the turntable motor 44 is connected to the insertion rod 46 through the belt transmission structure 45; a fixed platform 51 is arranged below the support base 5, and the fixed platform 51 is matched with the support base 5 to prevent rotation. The rotation of the rotating base 1 is realized.

[0040] More specifically, a protrusion 47 is formed on the rotating base 1, and the protrusion 47 forms the slot; a thrust bearing is provided on the support base 5, and after the insertion rod 46 is inserted into the slot, the protrusion 47 abuts against the thrust bearing. The thrust bearing is used to support the rotating base 1. This ensures that the rotating base 1 rotates more smoothly. The pulley of the belt transmission structure 45 is fixed to the insertion rod 46.

[0041] More specifically, the base adjustment motor 43 is used to connect the fixed platform 51 with the support base 5, and the connection point rises and falls relative to the fixed platform 51. The connection point is the position where the base adjustment motor 43 is connected to the rotating base 1. The output end of the base adjustment motor 43 is hinged to the fixed platform 51, so when the output rod of the base adjustment motor 43 is extended and shortened, the rotating base 1 can be raised and lowered. Multiple base adjustment motors 43 are raised and lowered by different distances, which can adjust the horizontal degree of the rotating base 1, thereby adjusting the rotating base 1 to a preset horizontal position.

[0042] Specifically, the attitude gyroscope 42 is disposed on the camera 2. The angular encoder 41 is directly or indirectly connected to the protrusion 47. More specifically, in some other solutions, the angular encoder 41 may also be connected to a pulley or to the rotating base 1.

[0043] Specifically, the driving member 4 also includes a coarse focus motor 48 and a fine focus motor 49 for adjusting the parameters of the camera 2. The gimbal also includes: a cloud platform instruction receiving board 6, a gimbal control circuit board 7, a wiper motor 31, a coupling 32, a micro switch 21, a coarse focus belt 8, and a fine focus belt 9. Among them, the coarse focus motor 48 is connected to one of the micro switches through the coarse focus belt 8, and the fine focus belt 9 is connected to another micro switch through the fine focus belt 9. The micro switch is a part of the camera 2. After the micro switch is turned or rotated at a certain angle, the camera 2 will be enlarged or reduced. Therefore, the coarse focus motor 48 and the fine focus motor 49 are rotated to realize the rotation of the micro switch at a certain angle. The wiper motor 31 is connected to the wiper 3 through the coupling 32. The wiper motor 31 drives the wiper 3 to rotate at a certain angle through the coupling 32, so that the wiper 3 contacts the light-transmitting lens 11 during the movement process, thereby cleaning the light-transmitting lens 11.

[0044] The cloud platform instruction receiving board 6 and the pan-tilt control circuit board 7 are both arranged in the rotating base 1. The cloud platform instruction receiving board 6 is used to receive instructions and send the instructions to the pan-tilt control circuit board 7.

[0045] When the pan-tilt control board is used to receive instructions for adjusting the pan-tilt angle, and after receiving the instructions, controls the turntable motor 44 to start and adjust the turntable angle, the encoder returns the current angle value of the pan-tilt to the pan-tilt control board in real time, and the pan-tilt control board sends the angle value to the cloud platform instruction receiving board 6, and the cloud platform instruction receiving board 6 sends the current angle of the pan-tilt angle encoder 41 to the cloud platform, and the cloud platform displays the current angle value in real time. When the turntable angle is adjusted to the preset angle position, the cloud platform sends an instruction to stop adjusting. When the pan-tilt control board receives the instruction, it controls the turntable motor 4419 to stop, and the pan-tilt stops adjusting the angle at this time, and the pan-tilt remains at the current preset angle position. The cloud platform is a remote operation control platform used to issue instructions for the pan-tilt angle.

[0046] When the PTZ control board receives the command of coarse focus / fine focus of camera 2, it first controls the coarse focus stepper motor and the fine focus stepper motor to start, driving the coarse focus belt 8 and the fine focus belt 9 to adjust the focal length of the camera 2 lens through the micro switch. When the camera 2 lens is focused to the target focal length, the cloud platform sends a command to stop adjustment. When the PTZ control board receives the command, it controls the coarse focus stepper motor and the fine focus stepper motor to stop running, so that the focal length of the camera 2 lens remains at the current focal length state.

[0047] When the gimbal control board receives the instruction to level the gimbal base, it first obtains the data of the attitude gyroscope 42. The angle data of the attitude gyroscope 42 are respectively the angles of rotation angle, roll angle and pitch angle. The gimbal leveling is mainly based on the current pitch angle and roll angle data of the attitude gyroscope 42. The position of the camera 2 base is adjusted from three positions by controlling the three base leveling motors to achieve the leveling effect. When the attitude gyroscope 42 detects that the current base has been leveled (that is, the angle values ​​of the pitch angle and the roll angle are 0, the current state of the three base leveling motors is maintained, thereby maintaining the current leveling state of the base.

[0048] When there are water stains / stains (including rain, snow, dust, etc.) on the transparent lens 11 of the pan-tilt housing, the imaging effect of the camera 2 is not good. At this time, the wiper 3 needs to be started to remove the stains on the transparent lens 11. When the pan-tilt control board receives the command to start the pan-tilt wiper 3, it starts the wiper motor 31, and then controls the rotation of the wiper 3 shaft, thereby controlling the rotation of the wiper 3. When the stains on the transparent lens 11 are removed, that is, the imaging of the camera 2 is not affected by the stains / rain and snow, the cloud platform sends a command to stop adjustment. When the pan-tilt control board receives the command to stop the wiper 3, it stops the wiper motor 31.

[0049] In some other embodiments, the coupling is connected to the wiper through a rotating shaft. A mounting shell is provided on the rotating shaft, the wiper is provided on the mounting shell, and the wiper is fixed to the mounting shell. A small motor and a rotating rod are provided in the mounting shell, and a cleaning roller is provided on the rotating rod. The rotating shaft drives the wiper to rotate through the mounting shell, so that the wiper cleans the light-transmitting glass sheet. The small motor drives the rotating rod to rotate, the axis of the rotating rod is parallel to the light-transmitting glass sheet, and the cleaning roller contacts the light-transmitting glass sheet, so that the cleaning roller cleans the light-transmitting glass sheet in a rotating manner, and the cleaning effect is improved by the rotation. The wiper is located on the side of the cleaning roller, so that the cleaning roller cleans the light-transmitting glass sheet first, and then the wiper cleans the light-transmitting glass sheet.

[0050] Specifically, a plurality of protrusions are formed on the rotating base at the edge of the light-transmitting glass sheet. The protrusions protrude outward relative to the light-transmitting glass sheet. A plurality of grooves are formed between the plurality of protrusions. When the cleaning roller and the wiper rotate to the outside of the light-transmitting glass sheet, the cleaning roller and the wiper will both contact the protrusions. The protrusions protrude outward relative to the light-transmitting glass sheet, which will increase the contact force between the protrusions and the cleaning roller and the wiper. As a result, the cleaning roller and the wiper are subjected to greater pressure, which can press out the moisture on the cleaning roller and the wiper, and then discharge it outward along the grooves, thereby preventing the pressed moisture from contacting the cleaning roller and the wiper for a second time.

[0051] More specifically, the width of the plurality of protrusions is smaller than the thickness of the wiper, so that when the cleaning roller and the wiper pass through the protrusions, they will continuously contact the protrusions, so that the protrusions will scrape and clean the cleaning roller and the wiper, scraping off impurities on the cleaning roller and the wiper, and the impurities will be accommodated in the groove body, thereby achieving the effect of cleaning the cleaning roller and the wiper.

[0052] In addition, the heights of the plurality of protrusions are different, so that the cleaning roller will be subjected to different scratching effects when contacting different protrusions. The extension directions of the plurality of protrusions all intersect with the axis of the rotating shaft.
