针对目前残留液检测中速率和准确率均较低的现象,基于红外线在相同距离不同介质中传递的时间有差异这一基本原理,设计了一种基于双红外传感器和AT89S52 的残留液检测系统。阐述了系统的硬件构成、软件设计流程及测试过程。实验表明,系统简单实用,在72 000 瓶/ 小时左右的高速灌装线上其检测准确率可达99% ,具有一定的实用价值。

A residual liquid inspection system based on double infrared sensors and AT89S52 was designed to resolve the low speed and accuracy problems. The fundamental of the system is that it takes different time for infrared to pass different media with the same distance. The hardware configuration, the software design flow, and the measurement process of the system were introduced. Experimental results showed that the system has the features of convenient and high accuracy; the accuracy is 99% while it is used in the beer filling line of 72,000 bottles per hour. It has practical application value.
