The Research of Measurement System Based on Linear CCD in Industrial Line

There were a lot of small work pieces in the industry, like the lamella and the small steel wire line etc. Some of them could not be touched directly, for high request in some production line to the works piece thickness accuracies which depend on an on-line examination for manpower could not satisfy a production line anymore. This paper introduced a kind of measure system based on the production line of linear CCD, with the control chip of EPM3064A and measure chip of TCD132. Sampling the output signal from CCD module and sending the datum to host computer, built by VB with AVR128 MCU in RS-232 serial communication mode and displayed the waveform images with binarization in real time and analyzed them. Finally, with the help of Key9 software to carry on unmanned auto supervision and realized message sending function. The experiment showed the precision, rapid of this system and good humanization of control effect as a result.
