Description
Technical field
The present invention relates to a kind of measuring device, it is specifically a kind of it is accurate measure high-speed imaging equipment damage the time device and
Method.
Background technology
There are two class high speed cameras on the market at present, one kind is the high-speed industrial based on Cameralink interface real-time Transmissions
Camera, another kind of is the high speed of self-contained storing devices or ultrahigh speed camera.
The A504K high speed cameras of first kind camera such as BASLER companies or the pco.1200hs high speed cameras of PCO companies, this
Class camera in the case that full resolution (about 1K × 1K) frame frequency generally in 500 frames/second~1000 frames/second, transmission range only about 8
~10 meters.
Second class camera is the CR-S3500 ultrahigh speed cameras such as Optronis companies, and the frame frequency of the camera is up to 3500
Frame/second, camera internal self-contained storing devices, first the image collected is pre-existed camera internal by high speed when work；Deng having stored
After image at certain data volume (such as more than 500 width), stop collecting work, then pass through kilomega network or exclusive data interface low speed
(for relative interior acquisition and storage speed) transmission image data to computer, realizes that image reproducing is shown.
For explosion, collision etc. extreme environments service condition under, the above two classes camera all will testing ground quickly
Damage, has little time to go out the image transmitting of shooting, it is even more impossible to realize the detection to camera working life at all.If far from examination
Scene is tested, then and does not have practical significance.

It is sent once by 1 microsecond, using 32 data representations, this status signal and picture signal is shared into same root optical fiber timesharing and passed
It is defeated；It is 10MHZ that the remote receiver end, which uses FPGA design timer, elapsed time clock frequency, and accuracy of timekeeping is 0.1 micro-
Second, FPGA design timer starts timing after receiving system command, when it receives the error signals that camera is sent out
When, stopping timing, or when the SFP+ optical port communication abnormalities of high speed camera, FPGA design timer stops timing, with
It is both upper to be subject to first comer；By reading the clocking value of FPGA design timer, the damage of high speed camera is accurately measured
Time.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention includes high speed camera and remote receiver two
Part, high speed camera and remote receiver are by 10G single mode optical fiber connecting communications, and transmission range is up to 2 kilometers~40 kilometers, high speed
Camera is responsible for the image of shooting and relevant information being sent to remote receiver in real time, and receiver is responsible for carrying out image and information
Real-time continuous storage and analysis, even if captured by before capable of completely retaining camera damage if high speed camera damage remote receiver
Image and information.
