Abstract: Abstract The article takes the checkout methods of ree of ripeness of mucilage glue as object in chemical fiber manufacture.The automatic checkout device, used C8051F410 system on chip as the core,designed for the ree of ripeness of mucilage glue, focuses on the stir motor’s constant speed controling through the test process, the management and detection of titration of NH4C1 liquor, the measurement of risistance of stir, and the judgement of the titration destination. In addtion, it has been compared with the traditional checkout methods on mucilage glue,and also analysed the result. The consequence suggests that, the automatic checkout method for the ree of ripenness of mucilage glue presented in this article has high accuracy, and the results are coincided with experimental data, which has profoundsignificance for enhancing the degree of automation chenckout of the ree of ripeness of mucilage glue in chemical fiber manufacture.

Key words: mucilage glue, ree of ripeness, Automatic Checkout
