Abstract
Description
Technical Field
[0001] The utility model relates to the field of monitoring devices, and specifically, to a panoramic monitoring camera with a pan-tilt head. Background Art
[0002] In the metallurgical industry, the safe operation of cranes has always been the focus of attention. As an important part of the crane safety monitoring system, video monitoring has also received wide attention. In order to monitor the entire crane operation scenario, a panoramic camera is required. This camera is composed of multiple small cameras and can perform panoramic shooting within a range of 90 degrees vertically and 180 degrees horizontally, enabling comprehensive monitoring of the entire crane operation scenario. Therefore, it is widely used in the crane safety monitoring system.
[0003] In addition, under the wave of intelligentization and automation, metallurgical cranes have also been involved in intelligent transformation. Currently, due to the reason that metallurgical cranes lift molten metal, full automation transformation cannot be achieved. Only the innovation of ground remote operation can be realized, that is, the operation mode is changed from on-board operation to ground operation to improve the working environment. At this time, the importance of video monitoring is extremely prominent, and only excellent video monitoring can ensure the safety of operation. In order to simulate the vision of the crane driver's cab, a panoramic camera is installed at the bottom of the driver's cab, which can effectively simulate the vision effect of the crane driver's cab. Therefore, panoramic cameras are also widely used in the project of crane remote operation transformation.
[0004] However, currently, there are not many manufacturers producing panoramic cameras, and those applicable to industrial occasions are even rarer. All panoramic camera products are fixed-position products, that is, they do not have a pan-tilt head, and the angle can only be adjusted manually. For example, a panoramic camera involved in Patent CN106803874A and a 360-degree panoramic camera involved in Patent CN101464556A do not adopt a pan-tilt head. This is basically not a problem in the civilian field, but in the industrial field, especially as the main monitoring device for crane monitoring, its installation has relatively strict requirements. The horizontal angle and vertical angle need to be finely adjusted. And over time, it will inevitably shift due to the vibration of the crane and requires readjustment. Without a pan-tilt head, only manual adjustment can be performed. Since the panoramic camera must ensure its field of view, there must be no obstruction above and below in the front of the installation position, and there must also be no obstruction in the left and right directions. This means that it must be installed under the abdomen of the crane, especially for installations in remote operation scenarios, it must be at the bottom of the crane driver's cab. As a result, installation and adjustment are extremely difficult. Moreover, since the crane is operating at a height of dozens of meters, the installation and adjustment of the panoramic camera are high-risk operations, posing a great threat to the personal safety of the operators, and the handling of its operation procedures is extremely cumbersome and time-consuming. Therefore, the current installation, subsequent maintenance, and adjustment of panoramic cameras are extremely difficult. Summary of the Invention

[0059] Specific implementation mode
[0060] The following combines specific embodiments to elaborate on the present utility model in detail. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all belong to the protection scope of the present utility model.
[0061] Embodiment 1
[0062] In this embodiment, panoramic acquisition is achieved through the splicing of two cameras. It is required that the horizontal field of view angle of a single camera is greater than 100 degrees, and the vertical field of view is greater than 80 degrees. Only in this way can it be ensured that the field of view after the splicing of the two cameras can meet the requirements of 180 degrees and the vertical field of view requirements. The pan-tilt needs to be able to achieve functions of left-right rotation, vertical rotation, and independent rotation of the camera.
[0063] In this embodiment, the two cameras are respectively fixed on a camera rotation drive gear 502, and then the two camera rotation drive gears 502 are meshed. In this way, the rotation of the two gears will drive the cameras to rotate relatively, and the included angle between the two cameras will change, so as to adjust the overall video field of view range.
[0064] In actual use conditions, because the vertical range of the field of view usually has different focus points, it may be necessary to be able to adjust the vertical angle of the camera assembly 5. However, in order to ensure the field of view, the installation position of this embodiment is usually difficult to construct, and for this reason, the installation position angle of this embodiment may not be ideal, but subsequent adjustments will be difficult to achieve due to the difficulty of the operation. Therefore, being able to electrically adjust the vertical angle of the camera is also a need that needs to be urgently addressed. In this embodiment, two cameras are installed together with a camera rotation transmission gear 502 on a bracket 3, and a bracket rotation transmission plate 303 is processed in the middle of the bracket 3. The top of the bracket rotation transmission plate 303 is a semicircular structure. Rotating with its center as the axis can drive the bracket 3 to rotate, thereby driving the two cameras to rotate together, so that the camera can be adjusted at a vertical angle. The vertical angle of the bracket 3 can be adjusted by driving the bracket rotation transmission plate 303 to rotate with a stepper motor.
[0065] Due to the difficulty of the above-mentioned installation and maintenance operations, the horizontal field of view of this embodiment may not meet the actual needs after installation, so it is necessary to adjust the horizontal field of view of the camera assembly 5 as a whole to meet the needs of the working conditions. Therefore, it is also an urgent need to realize the electric adjustment of the horizontal angle of the camera assembly 5. In this embodiment, the bracket rotation transmission plate 303 of the bracket 3 is connected to the support column 2 through a bracket rotation shaft. The rotation of the support column 2 can drive the bracket 3 to rotate together, so that the horizontal rotation of the bracket 3 can be realized, thereby driving the camera assembly 5 to rotate and realizing the adjustment of the horizontal angle of the camera assembly 5. A support column rotation transmission shaft 209 is processed on the top of the support column 2, which passes through the center of the disc base 1 and is connected to the support column rotation transmission gear 206, and is installed on the base 1. Then, a stepping motor drives the support column rotation drive gear 203 to engage with the support column rotation transmission gear 206, so that the support column 2 can be driven to rotate, thereby realizing the electric adjustment of the horizontal angle of the camera assembly 5 of this embodiment.
[0066] In order to ensure that the protection level of this embodiment can reach IP65 (IP level is the protection level of the housing of electrical equipment against foreign objects), and to provide all-round protection for the camera assembly 5, the internal structure of this embodiment is wrapped by a protective cover composed of a top protective cover 6 and a bottom protective cover 7, thereby achieving an overall protective effect, and the bottom protective cover 7 is made of a high-temperature resistant transparent material (such as tempered glass), thereby ensuring that the video acquisition of the camera will not be affected. The top protective cover 6 and the bottom protective cover 7 are fixed on the base 1 at the same time, making this embodiment a whole.
[0067] The camera module 5 of this embodiment adopts a POE interface. The feature of the POE interface is that through a single network cable, it can achieve Ethernet communication while also providing power to the device. In this embodiment, the circuit board 4 integrates a POE switch circuit 405, providing an external POE inlet interface 4021 and two internal POE interfaces. Through the external POE line, it is connected to the POE inlet interface 4021 to achieve both communication and power supply in this embodiment. The two internal POE interfaces are then connected to two camera modules 5 to achieve video acquisition. All drive motors in this embodiment are connected to the drive motor interface circuit 403 on the circuit board 4 and are controlled by the CPU circuit 404 integrated on the circuit board 4. Therefore, through the external POE cable, the control of each stepper motor in this embodiment can be achieved, thereby realizing the adjustment in three dimensions of vertical, horizontal, and the angle of the camera.

The POE power circuit 406 receives power from the POE inlet interface 4021 and supplies power to the circuit board 4 and the camera assembly 5. The switch circuit 405 is connected to the POE inlet interface 4021, the first camera POE interface 4022, and the second camera POE interface 4023. The CPU circuit 404 is connected to the drive motor interface circuit 403.
[0079] Working principle:
[0080] In this application, the horizontal rotation, vertical rotation, and self-rotation of the camera are respectively realized through the support column rotation drive assembly, the bracket rotation drive assembly, and the camera rotation drive assembly to adjust the panoramic view of the camera, so as to solve the problem that it is very difficult to construct the installation position due to the field of view requirements, and thus it is extremely difficult to maintain and adjust the equipment afterwards.
[0081] Among them, for horizontal rotation: the output shaft of the support column rotation drive motor 201 installed on the base 1 rotates to drive the support column rotation drive gear 203 to rotate. The support column rotation drive gear 203 meshes with the support column rotation transmission gear 206 to drive the support column rotation transmission gear 206 to rotate. The support column rotation transmission gear 206 drives the connected support column 2 to rotate horizontally, thereby driving the horizontal rotation of the bracket 3 and the camera assembly 5 connected to the support column 2. For vertical rotation: the bracket rotation drive motor 301 installed on the support column 2 drives the bracket rotation transmission plate 303 to rotate vertically through the bracket rotation shaft. The bracket rotation transmission plate 303 drives the entire bracket 3 and the camera assembly 5 on the bracket 3 to rotate vertically. For the rotation of the camera angle: the camera rotation drive motor 501 installed on the bracket 3 drives the camera rotation drive gear 505 to rotate. The camera rotation drive gear 505 meshes with any one of the camera rotation transmission gears 502 to drive the camera rotation transmission gear 502 to rotate. The camera rotation transmission gear 502 meshes with the other camera rotation transmission gear 502 to achieve the reverse rotation of the two camera rotation transmission gears 502, and further achieve the reverse rotation of the cameras connected to the two camera rotation transmission gears 502. During the reverse rotation process, the angle between the two cameras changes.
[0082] Embodiment 2
[0083] Embodiment 2 is a preferred example of Embodiment 1.
[0084] Such as Figures 6-7As shown in the figure, this embodiment is divided into two parts as a whole. One part is the internal functional structure, and the other part is the external protective structure. The external protective structure wraps the entire internal functional structure through a top protective cover 6 and a bottom protective cover 7. The bottom protective cover 7 is made of transparent material to meet the video acquisition needs of the internal camera assembly 5. The top protective cover 6 is made of aluminum alloy and serves as the external support body and the main load-bearing component. The top protective cover 6 and the bottom protective cover 7 are basically hemispherical structures. At the center of the topmost end of the top protective cover 6, a device mounting rod 601 is machined. Near the top of the device mounting rod 601, an annular groove is machined as the second fixed guide groove 602, which enables the entire device to be fixed to the mounting bracket through the fixing screws of the mounting bracket. The device mounting rod 601 is a tubular structure. At the center part of the tubular structure of the device mounting rod 601 where it is connected to the spherical surface of the top protective cover 6, an inlet hole 604 is drilled. In this embodiment, a drag cable form is adopted, and a POE cable connected to the circuit board 4 is included. The POE cable will pass through the inlet hole 604 and extend to the outside, with a length of about 500 millimeters. Due to the connection of the external cable, the upstream device can supply power to this embodiment and communicate with it. After the POE cable passes through, the central part of the device mounting rod 601 is potted to ensure that the protection level of this embodiment reaches IP65. Near the upper half of the spherical surface of the top protective cover 6, a safety rope hanging ear 603 is machined for hanging the safety rope. The other end of the safety rope is connected to the safety rope hanging ear of the mounting bracket to prevent the camera body from falling due to installation operation errors during the camera installation operation. The top protective cover 6 and the bottom protective cover 7 are both installed on the base 1 and sealed to ensure that the protection level reaches IP65.
[0085] As Figures 1-5 shown, the internal structure of this embodiment mainly includes: a base 1, a support column 2, a bracket 3, a first camera 51, a second camera 52, a support column rotation transmission gear 206, a support column rotation drive gear 203, a support column rotation drive motor 201, a bracket rotation shaft, a bracket rotation drive motor 301, a camera rotation transmission gear 502, a camera rotation drive gear 505, a camera rotation drive motor 501, and a circuit board 4.
[0086] The base 1 is in a disc shape and is the structural main body of the entire internal structure.
[0087] The support column 2 is connected to the center of the base 1 and penetrates to the other side of the base 1, and is connected to the center of the support column rotating transmission gear 206. The support column 2 can rotate freely along the center of the base 1. The support column rotating transmission gear 206 is tightly connected to the support column 2 and can rotate synchronously with the support column 2. The support column rotating drive motor 201 is installed on the lower plane of the base 1, and its output shaft penetrates to the other side of the base 1 and is connected to the center of the support column rotating drive gear 203. The output shaft of the support column rotating drive motor 201 can rotate freely in the through hole of the base 1. The support column rotating drive gear 203 is tightly connected to the output shaft of the support column rotating drive motor 201 and can rotate synchronously with the output shaft of the support column rotating drive motor 201. The support column rotating drive gear 203 meshes with the support column rotating transmission gear 206. Therefore, the rotation of the output shaft of the support column rotating drive motor 201 will drive the support column rotating drive gear 203 to rotate synchronously, and then drive the support column rotating transmission gear 206 to rotate, and then drive the support column 2 to rotate.
[0088] The bracket 3 is the main body of the installation structure of the camera assembly 5.
[0089] The first camera 51 and the second camera 52 are each installed at the bottom of their camera rotating transmission gears 502 and can rotate synchronously with the camera rotating transmission gears 502. The first camera 51 and the second camera 52 adopt the main body components of the bullet camera movement. The maximum horizontal field of view is more than 100 degrees, and the maximum vertical field of view is more than 80 degrees. In addition, its focal length can be adjusted remotely, and the adjustment range is from 2.7 to 8 millimeters. The camera rotating transmission gear 502 is installed at the bottom of the bracket 3, and its central axis penetrates through the camera rotating transmission gear mounting hole 306 on the bracket 3 to the top of the bracket 3 and can rotate freely along the camera rotating transmission gear mounting hole 306. The camera rotating drive motor 501 is installed at the top of the bracket 3 and fixed to the camera rotating drive motor mounting hole 308 of the bracket 3. Its output shaft penetrates through the camera rotating drive motor shaft output hole 307 on the bracket 3 to the bottom of the bracket 3 and can rotate freely along the camera rotating drive motor shaft output hole 307. The camera rotating drive gear 505 is installed at the bottom of the bracket 3, and its central hole is tightly connected to the output shaft of the camera rotating drive motor 501 and can rotate synchronously with the output shaft of the camera rotating drive motor 501. The camera rotating drive gear 505 meshes with one camera rotating transmission gear 502, and two camera rotating transmission gears 502 mesh with each other. Therefore, the rotation of the output shaft of the camera rotating drive motor 501 can drive the camera rotating drive gear 505 to rotate, and then drive one camera rotating transmission gear 502 to rotate, and then drive the two cameras to rotate relatively, realizing the adjustment of the camera angle, and then realizing the adjustment of the camera field of view.
[0090] Combine Figures 13-14As shown, a support rotation drive plate 303 is machined at the center of the support 3 in this embodiment. The top of the support rotation drive plate 303 is semi-circular, and a support rotation drive shaft mating hole 304 is machined at its center. A support rotation drive plate keyway 305 is also machined in the support rotation drive shaft mating hole 304. The support rotation drive plate 303 is installed in the support rotation drive plate mating groove 207 of the support column 2. The support rotation drive shaft mating hole 304 is concentric with the support rotation drive shaft installation hole 211 of the support column 2. The support rotation shaft is installed through the support rotation drive shaft installation hole 211 of the support column 2 and the support rotation drive shaft mating hole 304 of the support 3. The support rotation drive shaft keyway 311 of the support rotation shaft corresponds to the support rotation drive plate keyway 305, and the support rotation shaft and the support rotation drive plate 303 are synchronously rotated through a key. The support rotation shaft can freely rotate along the support rotation drive shaft installation hole 211 of the support column 2.
[0091] The support rotation drive motor 301 is installed on the support rotation drive motor installation column 302 of the support column 2, and its output shaft is connected to the support rotation drive motor mating shaft 310 of the support rotation shaft. The output shaft of the support rotation drive motor 301 and the support rotation shaft are synchronously rotated through the mating hole oval shape fit of the support rotation drive motor mating shaft 310. Therefore, the rotation of the output shaft of the support rotation drive motor 301 will drive the support rotation shaft to rotate, and then drive the support rotation drive plate 303 to rotate, and then drive the camera assembly 5 to rotate vertically, so that the vertical field of view of the camera assembly 5 can be adjusted. The horizontal rotation of the support column 2 can drive the support rotation drive plate 303 to rotate horizontally, and then drive the camera assembly 5 to rotate horizontally, so as to realize the adjustment of the horizontal field of view of the camera assembly 5.
[0092] Combined Figure 18 As shown, the circuit board 4 is installed on the circuit board installation column 401 at the bottom of the base 1, fastened with anti-loosening screws and fixed with glue to prevent loosening. The leads of the support column rotation drive motor 201, the support rotation drive motor 301, and the camera rotation drive motor 501 are all connected to the drive motor interface circuit 403 of the circuit board 4. The POE cable of the camera is connected to the Ethernet interface circuit 402 of the circuit board 4. The first camera 51 cable is connected to the first camera POE interface 4022, and the second camera 52 cable is connected to the second camera POE interface 4023.
[0093] As Figures 8-10As shown, the number of teeth of the main body of the camera rotation drive gear 502 is 80, the module is 1, and the thickness is 2 mm. A camera mounting base 5021 is machined at the bottom center of the camera rotation drive gear 502. The height of the camera mounting base 5021 is approximately 5 mm, and camera mounting holes 5024 are machined at its four corners. The four camera mounting holes 5024 are through holes. At the top of the camera rotation drive gear 502, counterboring is performed on the four camera mounting holes 5024 to ensure that the camera mounting screws do not protrude from the top plane of the camera rotation drive gear 502. Such a setting can ensure that the camera mounting screws will not fall off due to the obstruction of the camera rotation drive gear 502 and the bottom plane of the bracket 3, ensuring stable and reliable operation. A camera rotation drive gear shaft 5022 is machined at the top center of the camera rotation drive gear 502. The shaft length is about 10 mm. A first fixed guide groove 5023 is machined near the top edge of the camera rotation drive gear shaft 5022 for embedding a snap ring, so that the camera rotation drive gear 502 can be fixed by the snap ring to ensure that it will not fall off after being installed on the bracket 3. A camera rotation limit baffle 504 is machined on the edge of the camera rotation drive gear 502. The camera rotation limit baffle 504 is about 5 mm long, about 5 mm wide, and has the same thickness as the camera rotation drive gear 502. The camera rotation limit baffle 504 cooperates with the camera rotation positioning post 503 on the bracket 3 to ensure that the camera rotation drive gear 502 can only rotate within a certain angle range.
[0094] As Figures 11-12As shown, the support column rotation drive gear 203 and the camera rotation drive gear 505 in this embodiment have the same structure. Taking the support column rotation drive gear 203 as an example, the number of teeth of the support column rotation drive gear 203 is 10, the module is 1, and a support column rotation drive motor shaft fitting hole 2031 is opened at the center of the support column rotation drive gear 203. The support column rotation drive motor shaft fitting hole 2031 is oblate and is used in cooperation with the output shaft of the support column rotation drive motor 201, which can ensure that the support column rotation drive gear 203 and the output shaft of the support column rotation drive motor 201 can rotate synchronously. The number of teeth of the support column rotation transmission gear 206 is 80, the module is 1, and the thickness is 2 mm. However, teeth are only machined in a semi-circle of the working range. And support column rotation limit baffles 205 are machined at two edge positions of the working range of the support column rotation transmission gear 206. The thickness of the support column rotation limit baffles 205 is the same as that of the gear, and the length and width are both about 5 mm. The support column rotation limit baffles 205 cooperate with the support column rotation positioning piles 204 on the base 1, which can limit the rotation range of the support column rotation transmission gear 206 within a certain angle, because an excessive rotation angle will cause interference and pulling of the internal cables and equipment in this embodiment, and moreover, the orientation will be roughly determined during the installation of this embodiment, and only fine-tuning is required afterwards, without the need for large-scale adjustment. Therefore, the rotation angle of the support column 2 is limited within a range of 90 degrees. A support column rotation transmission shaft fitting hole 2061 is machined at the center of the support column rotation transmission gear 206. A section of support column rotation transmission shaft fitting notch 2062 is reserved in the support column rotation transmission shaft fitting hole 2061 and is machined into an arcuate hole, which can ensure that the support column 2 and the support column rotation transmission gear 206 can rotate synchronously after being fitted with the support column rotation transmission shaft 209.
[0095] As Figures 13-14 shown, the bracket 3 is composed of a rectangular flat plate and a bracket rotation transmission plate 303. The bracket rotation transmission plate 303 is welded at the center position of the rectangular flat plate, and the short side of the bracket 3 is parallel to the plane of the bracket rotation transmission plate 303. The thickness of the bracket rotation transmission plate 303 is about 5 mm, and the thickness of the rectangular flat plate is about 3 mm. The top of the bracket rotation transmission plate 303 is semi-circular, and a bracket rotation transmission shaft fitting hole 304 is machined at its center position. The bracket rotation transmission shaft fitting hole 304 is circular, but a bracket rotation transmission plate keyway 305 is machined at the top. The cooperation between the bracket rotation transmission plate keyway 305 and the bracket rotation transmission shaft keyway 311 can ensure the synchronous rotation of the bracket rotation shaft and the bracket rotation transmission plate 303. In addition, a camera rotation transmission gear mounting hole 306, a camera rotation drive motor mounting hole 308, a camera rotation drive motor shaft output hole 307, and a camera rotation positioning pile 503 are also machined on the rectangular flat plate.
[0096] As Figures 15-16As shown, the support column 2 is cylindrical as a whole, and its bottom is processed into a hemispherical shape. A part of the right side is flattened to serve as the mounting surface for the bracket rotation drive motor 301. However, about 10 mm is reserved at the top to ensure that the top is a complete cylinder, which can ensure smoother rotation after the support column 2 is installed on the base 1. A support column rotation transmission shaft 209 is processed at the center of the top of the support column 2. A section of support column rotation transmission gear mating notch 210 is processed at the top of the support column rotation transmission shaft 209. Correspondingly, a section of support column rotation transmission shaft mating notch 2062 is also provided in the central hole of the support column rotation transmission gear 206, forming an arch shape. In this way, after mating with the support column rotation transmission gear 206, it can be ensured that the support column 2 and the support column rotation transmission gear 206 can rotate synchronously. A bracket rotation transmission plate mating groove 207 is opened at the middle position of the spherical bottom of the support column 2 for mating with the bracket rotation transmission plate 303. A through hole is processed from one side of the bracket rotation drive motor mounting surface 208 at the center of the spherical center of the bottom of the support column 2 for installing the bracket rotation shaft. The driving end (bracket rotation drive motor mating shaft 310) of the bracket rotation shaft is thick, and the transmission end (bracket rotation transmission shaft 309) is thin. Therefore, the shaft hole on the side of the support column 2 corresponding to the bracket rotation motor drive mounting surface 208 is thicker, and the shaft hole on the other side is thinner. Such a design can ensure that the bracket rotation shaft will not slide and fall off after installation. At the middle part of the support column 2, bracket rotation drive motor mounting posts 302 are symmetrically processed on the cylindrical edge from one side of the bracket rotation drive motor mounting surface 208 to the other side. The bracket rotation drive motor mounting post 302 is a round-corner square column as a whole, and a bracket rotation drive motor mounting hole 3021 with a depth of about 10 mm is processed at the center from one side of the bracket rotation drive motor mounting surface 208. The bracket rotation drive motor mounting post 302 also has the function of limiting the bracket rotation transmission plate 303, ensuring that the rotation angle of the bracket 3 cannot be too large, resulting in interference with cables and equipment. In this embodiment, the rotation angle of the bracket 3 is limited within the range of 90 degrees.
[0097] As Figure 17As shown, the support rotation shaft is divided into two parts: the support rotation transmission shaft 309 and the support rotation drive motor matching shaft 310. The support rotation transmission shaft 309 is thinner, with a diameter of about 5 mm, and the support rotation drive motor matching shaft 310 is thicker, with a diameter of about 8 mm. The support rotation transmission shaft 309 is a solid shaft, and a support rotation transmission shaft keyway 311 is processed near the support rotation drive motor matching shaft 310. After the key is matched with the support rotation transmission plate keyway 305 of the support rotation transmission plate 303, the support rotation transmission plate 303 can be made to rotate synchronously with the support rotation shaft. A flat circular hole with a depth of about 8 mm is processed in the center of the support rotation drive motor matching shaft 310. The hole is the support rotation drive motor shaft matching hole, which is used to match the output shaft of the support rotation drive motor 301, and can ensure that the support rotation shaft and the output shaft of the support rotation drive motor 301 can rotate synchronously. When designing, it is necessary to ensure that the support rotation shaft is fully installed in the support rotation transmission shaft installation hole 211 of the support column 2, and both ends can be flush with the edge of the support column 2.
[0098] The driving motor used in this embodiment is a small stepping motor with a reducer, and its output shaft is set at an eccentric position. The reducer can ensure that the driving torque of the motor is large enough, and the deceleration effect can ensure that the adjustment is more precise and accurate. The eccentric output shaft setting can make the motor deviate from the driving center when installed, so that the installation position is more sufficient. A motor terminal box is set on the side of the motor away from the output shaft, and the motor control lead is led out. The motor is provided with two motor mounting holes for the installation and fixation of the motor.
[0099] like Figure 18As shown, the circuit board 4 is designed in a bow shape, which can effectively increase the area of the circuit board 4. When installed, the center of the arc of the circuit board 4 is concentric with the center of the base 1. The circuit board 4 includes an Ethernet interface circuit 402, a drive motor interface circuit 403, a CPU circuit 404, a switch circuit 405, and a POE power circuit 406. The Ethernet interface circuit 402 further includes a POE incoming line interface 4021, a first camera POE interface 4022, and a second camera POE interface 4023. The external incoming line cable is connected to the POE incoming line interface 4021 of the circuit board 4, the POE cable of the first camera 51 is connected to the first camera POE interface 4022, and the POE cable of the second camera 52 is connected to the second camera POE interface 4023. The POE power circuit 406 receives the power from the POE incoming line interface 4021 and, after processing, supplies power to each part of the circuit board 4 and also to the cameras. The switch circuit 405 is connected to three network interfaces, namely the POE incoming line interface 4021, the first camera POE interface 4022, and the second camera POE interface 4023, and is responsible for data processing and switching of these three network interfaces. The CPU circuit 404 is responsible for processing the control signals from the external network and controlling the drive motor interface circuit 403 so as to adjust the rotation angle of each drive motor according to the external control signals, and collecting the current signals of each motor so as to determine whether the corresponding motor has reached the limit position, thereby prohibiting over-rotation, performing motor protection, and calibrating the rotation position of the motor based on this to ensure the accuracy of the rotation angle.
