Description
Technical Field
The application relates to the field of Internet of things, in particular to a method for a main connecting line inside a pan-tilt camera.
Background
The monitoring camera is more and more intelligent as a modern home security product, a fixed version monitoring camera (without a motor and a lens can not rotate automatically) can not meet daily requirements, and thus a tripod head version monitoring camera (with a built-in motor and capable of controlling the rotation of the lens) is more and more popular. The device is provided with a device for bearing the camera to rotate in the horizontal direction and the vertical direction, and the camera is arranged on the holder to enable the camera to take pictures from a plurality of angles. Two stepping motors are arranged in the tripod head. The horizontal and vertical rotation angles can be adjusted by a limit switch. And is divided into an indoor pan-tilt and an outdoor pan-tilt.
The electric pan-tilt is suitable for scanning and monitoring a large range, and can enlarge the monitoring range of the camera. The high-speed attitude of the electric cradle head is realized by two actuating motors, and the motors receive signals from a controller to accurately operate and position. Under the action of the control signal, the camera on the pan-tilt can automatically scan the monitoring area and can also monitor the object under the control of the operator on duty in the monitoring center. Unlike a card machine with a fixed lens, the pan/tilt/zoom camera is limited by the structural specificity, and the hardware needs to adopt a split Board design with upper and lower pcba (printed Circuit Board assembly) as shown in fig. 1-2. The motherboard has a flat cable to board connector for fixing the connecting wires, and various control signals and power supply are fed on the wires. The design of the bottom board is simple, no active device is arranged on the board, and all control signals are sent from the main board or directly sent to the main board.
Because of the board-to-board design, the power and signal connections between the PCBAs become a very important and problematic issue. Unlike the card machine, the lens of the dockside machine may be in a repeatedly moving state (starting the cruise or human tracking function) all the time during the life cycle of the device. The underlying PCBA, however, is always in a relatively quiescent state within the device structure. The connecting wire between two PCBAs also will receive the power in horizontal and vertical direction always to produce repeatedly and twist reverse and buckle deformation, can greatly reduce the life of connecting wire. How long it can last, just also determine how long the life cycle of a cloud platform machine.

In the main board, no bus bar connector is provided. The WIFI module is replaced by an integrated module of WIFI + Bluetooth, and networking and interaction with the bottom plate can be achieved simultaneously.
