摘要:: 在纱线的生产过程中,拉伸性能检测是一重要工序.为了提高成品等级和质量,研制了纱线拉力试验机微机测控系统.该系统由主机、拉力测量传感器、延伸量测量传感器、自动返回定位单元和上位机组成,主机采用77E58单片机,采用高精度的A/D转换器,速率达100次/s;最大负荷1 kN;最小值0.01 N;精度等级:0.1级;试验速度范围0.005～500 mm/min;位移测量精度:示值的±0.1%以内;位移测量分辨率:0.01 mm.试验表明,该系统检测精度高,数据处理速度快,可以和建材、纺织、金属制品、纸制品等行业中使用的各类拉力试验机配套使用,具有良好的推广应用前景.

Abstract:: In the yarn manufacturing process，the detection of tensile properties is an important process．In order to improve product grade and quality，microcomputer control system for yarn tensile tester is developed．The system consists of the host，pull measurement sensors，extension amount measurement sensors，automaticreturn position unit and monitor computer system．The lord controls electric circuit is based on the 77E58sMCU and high-precision A／D converter，its rate reachs 100 times per second；the load range is 0．01N-1kN；the rate range of experimentation is 0.005～500 mm／min，the precision of displacement measurement isunder±0．1％．and the resolution of displacement measurement is 0．01 mm．Tests showed that the system notonly has high detection accuracy but also runs at faster data processing speed．Moreover，it may be appliedcompatibly with a kind of yarn tensile tester in building materials，textile，and metalwork and paper product．So，it has agood prospect of application．
