Design of Laser Scanning Diameter Measurement System for Packaged Goods

目的为适应包装物品测径的需求,设计面向包装物品的激光扫描测径系统。方法通过研究激光扫描技术在测距方面的应用,设计出适合包装物品测径需求的激光扫描测径系统装置,原理是将光源设计为可见激光,将包装防护的物品通过可见激光的测量扫描后,经过光电转换程序将光信号转化为电信号。转换后的电信号再经数据处理系统进行整理,得出准确结果,并在激光扫描测径系统中显示出来。结果该装置具有数字化的通信接口,与PC机连接组成智能化的包装物品测径装置,可对激光信号转化成电信号进行整理、分析和处理,并进行实时跟踪、监控,形成记录,如在包装物品扫描测径过程中出现意外时,能及时反馈给控制系统。结论该激光扫描测径系统实现了包装物品的全自动化、快速、精确测径,可靠性高,可进行动态、流水化、实时在线检测,同时对包装物品没有损伤。

This work aimed to design a laser scanning diameter measurement system for packaged goods to meet the demand for diameter measurement of packaged goods. This paper designed a laser scanning diameter measurement system device meeting the demand for diameter measurement of packaging materials based on the study on application of laser scanning technology in terms of distance measurement. Te principle was to use visible laser as the light source, after measurement and scanning of the packaged goods with visible laser, the light signals were transformed into electric signals. The transformed electric signals were arranged using data processing system to get accurate results, which were displayed in the laser scanning diameter measurement system. The device had a digitized communication interface, which was connected with the PC to constitute the diameter measurement device for packaged goods, and could transform the laser signals into electrical signals followed by arrangement, analysis and processing. Real-time tracking and monitoring were realized, forming records. If accidents occurred in the process of scanning diameter measurement of packaged goods, the information could be feedback to the control system. The laser scanning diameter measurement system could achieve fully automated, fast and precise diameter measurement, with high detection efficiency, high reliability, and capability of dynamic, streamline and real-time online testing, and meanwhile causing no damage to the packaged goods.
