摘　　要：残留液检测是啤酒灌装线上空瓶灌装前的必检项目之一。人工检测已不能满足高速灌装的要求,而目前的残留液自动检测系统存在安全性差、检测准确性和可靠性低等问题。为此,本文提出了基于电容耦合原理的残留液检测方法,并设计制造了检测样机。实验表明,本文所用方法在保证检测安全性前提下,能够有效提高检测的准确性和可靠性,具有一定的实用价值。Residual liquid inspection is an important process before filling up in the beer filling line. It aims to inspect that whether there is residual alkali liquid in the inspecting bottles and improve the quality of the beer. At present, manual inspection can’t meet the requirements of high filling speed and high-accuracy inspection. While the automatic residual liquid inspection system at present has some defect such as poor security, low accuracy and reliability. Therefore, this paper proposes a new method for residual liquid inspection which is based on the principle of capacitive coupling and has realized non-contact measurement for residual liquid remaining in empty bottle. The inspection prototype is also designed for detection. According to experiments, it is indicated that this method can effectively improve accuracy, reliability and security of the detection and has high practical value.
