Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
The utility model proposes a kind of image long haul transmission system, this system can be transferred to image the position beyond 10cm in real time, exactly.Fig. 1 is the structure chart of a specific embodiment of this system, and as shown in Figure 1, this system comprises: camera module 101, serializer 102, high speed serial transmission cable 103 and deserializer 104.The output end of image of the input termination camera module 101 of serializer 102, the top of the output termination high speed serial transmission cable 103 of serializer 102; The terminal of high speed serial transmission cable 103 connects the input of deserializer 104.
The camera module 101 is here the acquisition device of image, can adopt the MT9V022CMOS sensor module of company of Micron Technology to realize.This sensor module can be exported the image information of 752 * 480 resolution the soonest with the speed of 60 frame/seconds, have very high frame speed simultaneously and connect near infrared susceptibility.MT9V022CMOS sensor module parallel output signal comprises following 11 holding wires: eight bit data line D0～D7, line synchronizing signal LINE_VALID, frame synchronizing signal FRAME_VALID, pixel clock signal PIXCLK.
In the utility model, serializer 102 and deserializer 104 can adopt the FIN212AC integrated chip of fairchild company (Fairchild) to realize.This chip is by above drawing or drop-down input pin DIRI can realize the function of serializer (DIRI equals 1) or deserializer (DIRI equals 0).FIN212AC chip is supported 12 parallel-by-bit data inputs, and the parallel speed of the highest support is 40MHz, and input signal format is YUV or RGB, is used for the system of long line transmitting image.Meanwhile, FIN212AC chip internal is integrated LVDS transceiver, has simplified hardware circuit design, has improved the stability of system.FIN212AC integrated chip is reduced to two pairs of Difference signal pair transmission data by 12 parallel-by-bit data transmission interfaces.When FIN212AC is during as serializer, difference output is to being DSO+/-and CKSO+/-signal; When as deserializer, difference input to be DSI+/-and CKSI+/-.
FIN212AC chip is used as serializer 102, can realize and turn the function of string.After eight bit data line D0～D7, line synchronizing signal LINE_VALID in parallel signal and frame synchronizing signal FRAME_VALID serialization, by DSO+/-differential pair, export; Pixel clock signal PIXCLK exports by CKSO+/-differential pair.
FIN212AC chip is used as deserializer 104, can realize string and turn function also.Serial input DSI+/-differential pair is converted to eight bit data line D0～D7, line synchronizing signal LINE_VALID and the frame synchronizing signal FRAME_VALID in parallel signal; CKSI+/-differential pair is converted to pixel clock signal PIXCLK.
The type selecting of high speed serial transmission cable 103 is different, and the transmission speed of the high-speed serial data of serializer 102 outputs is just different, and in transmission range situation far away, this has influence on the image transmitting real-time of this system.Therefore, high speed serial transmission cable 103 is selected 5 class twisted-pair shielded wires conventionally, to reduce the interference in transmitting procedure, improves the antijamming capability of transmitting procedure.Certainly, in order to match with transmission range better, avoid causing the waste of resource, can also select different types of cable as high speed serial transmission cable 103 according to the difference of transmission range, for example, when transmission range is less than 0.5m, high speed serial transmission cable 103 can be selected flat cable, certainly, the length of this flat cable is less than 0.5m certainly; When transmission range is between 0.5m to 10m time, high speed serial transmission cable 103 can be selected 3 class twisted-pair feeders, and the length of this 3 class twisted-pair feeder is also between 0.5m to 10m; When transmission range surpasses 10m, high speed serial transmission cable 103 can be selected category 5 twisted pair or super category 5 twisted pair, and the length of this category 5 twisted pair or super category 5 twisted pair also will surpass 10m.
