Abstract
The utility model discloses a high-speed dome camera capable of supporting an HD-SDI interface, which mainly comprises three parts of a camera core, a master control board and an interface board; and the camera core is connected with the master control board through an FPC (Flexible Printed Circuit) flat cable, and the master control board is connected with the interface board through a conductive slip ring. The high-speed dome camera supports the real-time high-definition images output through the HD-SDI interface, no any compression is carried out to the image data, the vision data is output through the single 75 Ohm coaxial cable, and the most real high-definition video source image can be restored through the HD-SDI decoding device at the receiving end, so that the high-definition real-time monitoring is realized.
Description
Technical field
The utility model relates to technical field of security and protection, relates in particular to a kind of high speed ball-shaped camera that utilizes single coaxial cable to export the support HD-SDI interface of high-definition real-time image.
Background technology
Along with the development of HD video technology, video monitoring is more and more higher to the requirement of high-res, high image quality, and the HD-SDI interface is mainly used in the digital television broadcasting system, realizes the transmission of uncompressed video image, satisfies HD video monitoring demand.
The high speed ball-shaped camera relies on advantages such as high speed rotating, big multiple zoom, monitoring range be wide, easy to operate, just further enlarges range of application.High speed ball-shaped camera commonly used need use the conducting slip ring device to transfer, and in the face of the HD-SDI signal rate up to 1.485Gb/s, the product difficulty of the high speed ball-shaped camera of development support HD-SDI interface is very big.
High speed ball-shaped camera product in the market, the common video way of output has the CVBS interface, S-Video interface, network interface etc.Wherein CVBS and S-Video interface are exported analog video signal usually, can't realize high clear video image output.In addition network interface is exported the video format that encoding compression is H.264 crossed by the Ethernet mode, though can realize high-definition image output, this video image is not a raw image data, and has certain time-delay.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of high speed ball-shaped camera of the HD-SDI of support interface is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of high speed ball-shaped camera of supporting the HD-SDI interface, mainly form: camera movement, master control borad and interface board by three parts; Wherein, connect by the FPC flat wire between described camera movement and the master control borad, link to each other by conducting slip ring between master control borad and the interface board.
The beneficial effects of the utility model are, the support of the utility model equipment is exported real-time high-definition image by the HD-SDI interface, view data is not passed through any compression, video data utilizes single 75 ohm coaxial cable lines output, after through receiving terminal HD-SDI decoding device, just can restore the most real HD video source images, thereby realize high-definition real-time monitoring.
Description of drawings
Fig. 1 is the block diagram of system of the present utility model.
Embodiment
The utility model equipment adopts idea of modular, mainly comprises: camera movement, master control borad and interface board.Wherein use the FPC flat wire as signalling channel between movement and the master control borad.Use the conducting slip ring device to connect transmission associated video and control signal between master control borad and the interface board.
Camera movement output 16bit YCbCr image data format gather this image data format go forward side by side row cache and scrambling encoding process by FPGA on the master control borad, and the data-driven after will handling is to the conducting slip ring device.Need to use a primary processor to come controlling level direction and vertical direction stepping motor on the master control borad simultaneously, and support to communicate by letter with external user interface with movement.
Interface board can adopt the LMH0040 chip, the view data that the conducting slip ring termination is received is carried out the serialization processing, and drive the bnc connector end that is sent to 75 ohm.Interface board also will be imported the operating voltage that power source conversion becomes fixed value simultaneously, be the disparate modules power supply of whole system.
The distinguishing feature of the utility model equipment is exactly an original image of gathering the high definition camera by FPGA, does not do any compression and handles, and directly encodes and transmission process rear end 75 ohm coaxial cable lines output HD-SDI vision signal.
Below in conjunction with drawings and Examples the utility model is further specified, it is more obvious that the purpose of this utility model and effect will become.
This equipment adopts idea of modular, mainly is made up of three parts: camera movement, master control borad and interface board.Wherein connect by the FPC flat wire between camera movement and the master control borad, transmit by conducting slip ring between master control borad and the interface board.
The camera movement can adopt Hitachi's movement of 130W pixel, these movement output 16bit YCbCr data and row, field sync signal.The original image signal of Hitachi's movement output transfers to master control borad through 36pin FPC winding displacement, use the Spartan-3A series of X C3S200A model FPGA of Xilinx company to gather this raw image data on the master control borad, behind buffer memory, press the output of SMPTE reference format, after scrambling and encoding process, export the conducting slip ring device to 5bit LVDS data and 1bit LVDS clock signal.
Master control borad can select for use the LPC2365 of grace intelligence Pu company to come controlling level direction and vertical direction stepping motor, this processor is by 8 I/O mouth output parallel datas, behind four road 8bit D/A converters, export two groups of L6219DSA drivers respectively to, every set drive drive the counterparty to stepping motor.This processor uses UART1 commentaries on classics RS485 to realize communicating with external user interface simultaneously, uses UART0 and camera movement to communicate, and realizes focusing on, becomes operations such as times control.This processor can pass through I2C interface accessing eeprom memory in addition, reads preset information and carries out subsequent treatment.
Interface board can use the LMH0040 chip of National Semiconductor to receive 5bit LVDS data and 1bit LVDS clock signal on the conducting slip ring device, is urged to 75 ohm of bnc connectors through single channel serialization processing and with the HD-SDI signal.
In addition, interface board also the outside is imported the 24V power source conversion be internal system needed+12V ,+5V ,+3.3V, can normal steady operation to guarantee whole system.
