Design Of Data Collection System For Quartz Tube Measurement Instrument

This subject is cooperated with Jiuzhi photoelectron material technology Ltd. in Langfang China which full name is the measurement system of parameters for quartz glass tube. This thesis designed the data collection and the photoelectric receiver of the measurement system. Parameters Measurement for quartz glass tube which is part and parcel in manufacture provides a basic basis for quality inspecting. Currently, home product lines use manual skill and laser scanning technology to inspect quartz glass tubes, developing high precision automatic measurement apparatus meets the demand of glass tube merchants. The instrument we developed which make use of the liner CCD and step-type electromotors controlling machine can largely measure large-scale parameters of glass tubes. And you just have to set the data of the measured tube, our software designed in environment of Visual C++6.0 for instrument can measure tubes automatically. This paper discussed the principle that CCD used in measuring glass tubes, CCD mechanical spliced equipment for imaging system and data collection circuit of CCD.The main tasks of this thesis are listed as follows:1. We bring forward a scheme of glass tube measurement system comprised of multi-ccds chip, AD conversion, static memories and ISA-interface imaging processing card.2. Designed precise and flexible mechanics for multi-ccds receiver.3. Contrived TCD1500C drivers employing FPGA(field programmable logic gate array).4. Designed the ISA-interface data collection circuit of CCD.5. Developed the imaging collecting software of CCD for the measuring instrument and partial control software.
