Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

Fig. 1a is a schematic structural diagram of an existing pan-tilt camera according to an embodiment of the present application. The pan-tilt camera in fig. 1a includes a pan-tilt 101 and a dome camera 102, wherein two motors are installed in the pan-tilt 101, one of the motors is responsible for rotation in a horizontal direction, the other motor is responsible for rotation in a vertical direction, and the angle of the horizontal and vertical rotation can be adjusted by a limit switch, so that the dome camera can pick up images from multiple angles. The interface board in the pan-tilt 101 for expanding the interface of the pan-tilt camera and the main control board in the dome camera 102 for processing the image or video data collected by the pan-tilt camera generally perform electric energy transmission and data transmission in a wired manner such as a conductive slip ring. The conductive slip ring mainly comprises an electric brush, a brush holder, a conductive ring, an insulating material, a bonding material, a combined support, a precision bearing, a dust cover and other auxiliary parts, wherein the electric brush is made of elastic metal material, and is contacted with the slip ring through elastic deformation to form an electric contact.

Fig. 1b is a schematic structural diagram of a conductive slip ring according to an embodiment of the present application. The conductive slip ring in fig. 1b is a cap-type conductive slip ring, the shell is provided with a slip ring with a circular flange, the conductive ring part is generally designed to be a rotor, the electric brush part is a stator, the cap-type flange is fixed with the stationary end of the device through a pin, the slip ring is fixed with the rotating end of the device, the structural design and the assembly process of the cap-type slip ring directly determine the performance of the cap-type slip ring, and key parameters include: (1) brush pressure (contact forward force between brush and conductive ring); (2) a contact structure of the contact; (3) the swinging degree of the electric brush when the conducting ring rotates; (4) a gap between the brush wire and the brush frame.

Because the life of electrically conductive sliding ring is 100 ten thousand changes, and the life of cloud platform is 132 ten thousand changes, lead to the cloud platform camera to carry out electric energy transmission and data transmission through the wired mode such as electrically conductive sliding ring and can't satisfy the life-span demand of cloud platform to because electrically conductive sliding ring can only satisfy hundred megacommunications, can't satisfy giga communications, lead to unable transmission high definition or super clear video. In addition, under the condition of external vibration impact, the characteristic parameters of the transmission path of the conductive slip ring cannot be determined, so that the stability of the transmitted information is poor. Therefore, the existing cradle head camera cannot meet the service life requirement of the cradle head when carrying out wired power supply and communication, and cannot meet the problem of poor stability of kilomega communication and transmission information.

In view of this, the embodiment of the application provides a pan-tilt camera, which can realize wireless power supply and communication between an interface board and a main control board, and avoid the problems that the service life requirement of the pan-tilt cannot be met, the gigabit communication cannot be met, and the stability of transmitted information is poor when wired power supply and communication are performed between the interface board and the main control board in the existing scheme.

The second communication module 206 is configured to receive data sent by the first antenna array 207 and the first antenna array 208 through the second antenna array 209 and transmit the received data to the main control board 202, or send data transmitted by the main control board 202 to the first antenna array 207 and the first antenna array 208 through the second antenna array 209.

Therefore, the cradle head camera can avoid the problems that the service life requirement of the cradle head cannot be met, the gigabit communication cannot be met and the stability of transmitted information is poor when power supply and communication are realized in a wired mode such as a conductive slip ring in the existing scheme. Further, in the pan-tilt camera, since the transmit power conversion module 203 and the first communication module 205 share the first antenna array 207 and the first antenna array 208, the receive power conversion module 204 and the second communication module 206 share the second antenna array 209, thereby reducing the size and cost of the pan-tilt camera.
