It is provided with to connect multiple interfaces of CCD in reason module, multiple interfaces are corresponded with multiple CCD；Individual signals handle mould
Block can be by drive signal parallel output to multiple CCD, and the output signal of multiple CCD is located in advance with parallel processing manner
Reason；When individual signals processing module is to sampling module image signal transmission, the image corresponding to multiple CCD is believed in a serial fashion
Number output is to sampling module；When individual signals processing module carries out Serial output to the picture signal of multiple CCD, by setting when
Length exports the picture signal of single CCD.
The present invention the course of work be：During test, operating personnel are first the upper corresponding CCD to be measured of interface connection, so
Operating personnel are operated on host computer afterwards, are selected the output signal transmission of which CCD to be measured to host computer, select operation
After finishing, host computer just controls drive module and Image Acquisition control module to carry out corresponding actions, wherein, drive module is according to upper
The order of position machine generates corresponding drive signal and synchronizing signal, and drive signal and synchronizing signal are exported to Image Acquisition control
Molding block, Image Acquisition control module are selectively exported drive signal and synchronizing signal to selected according to the order of host computer
Signal processing module, meanwhile, Image Acquisition control module will be at synchronizing signal is exported to sampling module and will be selected signal
Module is managed to gate with sampling module；After receiving drive signal and synchronizing signal, signal processing module is by interface by drive signal
Loading is on CCD to be measured, after CCD to be measured generates output, signal processing module by the output signal of interface CCD to be measured,
Then (i.e. AD quantification treatments) is pre-processed to output signal, obtains picture signal, then signal processing module is according to synchronization
Picture signal is transmitted to sampling module by signal, is adopted at this point, sampling module synchronizes picture signal also according to synchronizing signal
Sample, and the image data that sampling is obtained is exported to upper machine；Signal processing module to the output signal of multiple CCD to be measured into
During row Serial output, the picture signal of single CCD to be measured is exported by the duration of setting, if the image of the first CCD to be measured
When the output duration of signal reaches setting value, signal processing module stops the picture signal of the first CCD to be measured of output, then proceedes to
The picture signal ... for exporting the second CCD to be measured is finished up to the picture signal of the last one CCD to be measured exports, then signal
Processing module stops output.
It is understood based on aforementioned operation process, when it is implemented, we can be with compilation operation program, by operation sequence according to sequential
Ground exports control instruction to drive module and Image Acquisition control module, in this way, with regard to device can be made multiple to be treated selected automatically
The output signal for surveying CCD is transmitted to host computer successively, alternatively, making output signal of the device automatically by the CCD to be measured connected
Alternate transmission is easy to operate to host computer.
After the present invention program, the Image Acquisition part of test device and signal processing are relatively independent, designer
Member can be the individually designed circuit of the two, so as to simplify the complexity of circuit, meanwhile, ccd output signal is pre-processed
Circuit modular construction may be employed, us is allow to extend the CCD quantity to be measured of access on a large scale, is once connected
Operation can just access substantial amounts of ccd signal to be measured, so as to efficiently complete the test operation of super multi-tap CCD.It is adopted in the present invention
Electric controling mode is common technique, and if any part not to the utmost, those skilled in the art should understand this with the prior art
