| 目的 针对当前航空炮弹包装盒密封性检测存在的不足，设计一种基于LabVIEW的航空炮弹包装盒和小型航空弹药引信，以及火工品包装密封性检测系统。方法 将待检包装置于检测平台密封箱内，将PLC控制器作为下位机，控制加气机和气体电磁阀工作。先向密封箱内充气，达到设定压力后保压一段时间，再利用气压传感器采集箱内的气压信号，经调理后送入USB数据采集卡，并传到以LabVIEW作为开发平台的上位机中，对采集的信号进行存储、处理与显示。结果 对预先选取的2个包装盒进行验证，分别置于1，2号密封箱内，测得气压下降率分别为13.82%和3.45%，经分析认为气压下降率＞5%即认定包装失封，因此判定1号包装盒密封失效，2号密封良好。结论 基于LabVIEW的测试系统具有自动化程度高、可扩展性强、搭建方便等特点，对提升航空弹药的保障效率有一定意义。 |

| The work aims to design a kind of airborne shells packaging box, small aerial ammunition fuze and packaging airtight detection system based on LabVIEW for making up the shortcomings of airtight detection of airborne shells packaging box. The packaging to be inspected was placed in the sealed box on the testing platform, and the PLC controller was used as the lower computer to control the inflator pump and the gas solenoid valve. First, the gas was inflated into the sealed box, and the pressure was kept for a period of time when reaching the set pressure. The gas pressure signal in the box was collected by the gas pressure sensor and then sent to the USB data acquisition card after conditioned, and transmitted to the upper computer with LabVIEW as the development platform. Then, the collected signals were stored, processed and displayed. Two packing boxes were pre-selected for verification and placed in No.1 and No.2 sealed boxes. The pressure drop rates were 13.82% and 3.45%, respectively. After analysis, when the pressure drop rate was φ＞5%, the packing lost sealing property, so the sealing property of No.1 packing box was poor and that of No.2 sealing was judged to be good. The test system based on LabVIEW has the characteristics of high automation, strong expansibility and easiness in construction, which has certain significance for improving the support efficiency of aerial ammunition. |
