【摘要】 瓶装液位情况是工业生产中较为关注的参数。针对现有的液位检测方法不适于非透明材质的瓶体或受限于安全性等问题，提出利用微波强穿透性、非接触、无损伤的特性搭建液位检测系统对瓶装液位进行检测。首先，在瓶体静态放置条件下通过改变液位进行电压值的测量，根据电压值的变化情况得出微波天线测量液位的敏感区域；然后，将液位值调整在微波天线测量的敏感范围内，启动传送带分析在动态场景中液位检测的响应时间。实验结果表明：该检测系统能够明显区分在1.5 cm变化范围内的液位值，检测精度优于1 mm,同时可满足工业现场对于检测速度的要求，能够适应灌装生产线的检测需要。更多还原

【Abstract】 Bottled liquid level is a parameter that is of great concern in industrial production.Aiming at the problem that some of the existing liquid level detection methods are not suitable for non-transparent material bottles, while others are limited by safety and other issues, using characteristics of strong penetration, non-contact and non-destructive of microwave are proposed to build liquid level detection system to detect bottled liquid levels.Firstly, the voltage value is measured by changing the liquid level under the static placement condition of the bottle, and the sensitive area of the microwave antenna measurement of the liquid level is derived according to the change of the voltage value.Then the liquid level value is adjusted within the sensitive area of the microwave antenna measurement, and the conveyor belt is started to analyze the response time of the liquid level detection in the dynamic scene.The experimental results show that the detection system can clearly distinguish the level value in the range of 1.5 cm change, the detection precision is prior to 1 mm, which can meet the requirements of the industrial site for the detection speed and can adapt to the detection needs of the filling production line.更多还原
