摘　　要：纸张挺度测试仪用于造纸行业中对纸张试样抗弯曲强度的精确测量,以便于在造纸流程中对纸样质量的实时控制。本文介绍了测试仪的工作原理,利用MSP430单片机设计出新型的精度为1/1000的纸张挺度测试装置,分析了该装置中单片机控制步进电机中断和A/D采样转换中断产生的冲突和对测试结果的影响以及改进办法,并且实现了Huffman压缩算法对采样数据的压缩并传输到上位计算机。目前,改装置已用于工业实践,工作稳定,可靠。In order to monitor paper quality timely, Paper Stiffness Testing Apparatus is used in paper production industry to measure Anti-pressure stiffness accurately. This paper introduce the apparatus works principle, and designed a new stiffness-testing apparatus which precision is 1/1000 with MSP430.Besides, the interruption collision between stepper motor controlled by the MCU and A/D sampling and its influence to the testing results, improve method are analyzed, the transmission of the testing results compressed by Huffman Algorithm to the upper computer is implemented. Now this apparatus works steadily and reliably in the industry practice.
