Technical field
The present invention relates to a kind of detection board, particularly relate to a kind of simulation photographic head based on USB3.0 and detect board。
Background technology
Flourish along with image photographic head industry, relates to camera lens and resolves multiple fields such as Force meansurement, vehicle-mounted pick-up field, mobile phone camera, moving camera。The existing photographic head mostly still being simulation class such as vehicle-mounted module, along with the lifting of simulation class photographic head frame per second and pixel, the interface of USB2.0 cannot meet the demand of image transmitting。And relatively multi-scheme can not meet the demand for the output of photographic head arbitrary resolution before。
Summary of the invention
The present invention proposes a kind of simulation photographic head based on USB3.0 and detects board, and it is in order to meet the analysis transmission of the higher higher frame rate image of parsing power, can the demand of multiple resolution also for satisfied compatible parsing。
The solution of the present invention is: a kind of simulation photographic head based on USB3.0 detects board, and it video decoding circuit including being sequentially connected in series, level shifting circuit, FPGA receive circuit, USB3.0 control circuit, PC；This video decoding circuit receives PAL/NTSC/SECAM analog signal output video signal ITU-RBT.656 to this level shifting circuit, is just received circuit by this FPGA through the level conversion of this level shifting circuit and receives；This video decoding circuit adopts TVP5150AM1 chip, converts analog signals into parallel port data signal, makes this FPGA receive circuit and transmits to this USB3.0 control circuit with the signal rate of 100M, and this USB3.0 control circuit transmits this PC with the signal rate of 5G。
As the further improvement of such scheme, by heat dissipating silicone grease and/or radiating silica gel sheet heat radiation between this detection board and the shell housing this detection board。
Further, heat dissipating silicone grease and/or radiating silica gel sheet have band viscosity。
The invention have the benefit that the present invention passes through the design to video decoding circuit, meet the analysis transmission of the higher higher frame rate image of parsing power, also meeting that compatibility resolves can the demand of multiple resolution。

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated。Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention。
Seeing also Fig. 1 to Fig. 4, video decoding circuit that the simulation photographic head detection board based on USB3.0 of the present invention includes being sequentially connected in series, level shifting circuit, FPGA receive circuit, USB3.0 control circuit, PC。This video decoding circuit receives PAL/NTSC/SECAM analog signal output video signal ITU-RBT.656 to this level shifting circuit, is just received circuit by this FPGA through the level conversion of this level shifting circuit and receives。
As shown in Figure 2, this video decoding circuit adopts TVP5150AM1 chip, converting analog signals into parallel port data signal, make this FPGA receive circuit and transmit to this USB3.0 control circuit with the signal rate of 100M, this USB3.0 control circuit transmits this PC with the signal rate of 5G。Being employed herein by the TVP5150AM1 of ST company, this chip can convert analog signals into parallel port data signal, and the sequential of parallel port signal is as shown in Figure 3。The present invention, by design to video decoding circuit, meets the analysis transmission of the higher higher frame rate image of parsing power, can the demand of multiple resolution also for satisfied compatible parsing。Based on the test sectional drawing of the transfer rate effect simulating photographic head detection board of USB3.0, as shown in Figure 4。
In order to ensure the heat radiation of whole detection board, radiating treatment can have been done for the chip of bigger caloric value in the design of the shell of detection board, heat dissipating silicone grease and radiating silica gel sheet heat radiation can be passed through, as dispelled the heat by band viscosity thermal grease fat between chip and shell。
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention。
