摘要
为解决传统危险货物包装气密检测中存在的准确性低、易漏检、程序繁琐等问题,利用红外成像和控制技术,首次研制了一种新型红外热成像气密检测仪。介绍了检测仪的结构与工作原理,硬、软件的特征及性能指标,并设计了相应的检测方法和流程。测试结果表明:该设备具有响应速度快、温度分辨率高、非接触式测量的优点;能满足现行检测标准要求,检测过程的数字化水平和安全防护性能得到了较大提高;同时能对泄漏点进行准确定位,有利于对缺陷产品质量和生产工艺进行改进。
In order to solve the problems of low accuracy,leakiness and tedious processing existing in traditional airtight testing of dangerous goods packaging,a new type of infrared imaging airtight detector has been developed for the first time by using infrared imaging and controlling technology.The structure and working principle of the detector were introduced with the characteristics and performance indicators of its hardware and software described,while the corresponding detection method and process were established.The results showed that the device had the advantages of quick response speed,high temperature resolution and non-contact measurement,which could completely satisfy the requirement of the current testing standard,with the testing process of digital levels and safety performance improved.In the meanwhile,it could accurately locate the leak point of the packaging,which could help to improve the quality of defective products and process.
