The Research and Development of Automatic Collection and Treatment System of Triaxial Shear test Data

本系统以3只压力传感器代替周围压力、反压力和孔隙压力测试仪表,以2只位移传感器代替2只位移百分表。系统实现数据采集与处理(计算、显示、制图等)的自动化,减轻了劳动强度,以汉字说明和人机对话方式进行试验。试验过程提示明确,并可由屏幕显示各种参数变化,主要技术指标达设计要求。

The research and development of automatic collection and treatment system of triaxial shear test data. The system uses 3 pressure transducers to replace measuring instruments for ambient pressure, back pressure and pore pressure, and 2 displecement transducers to replace displecement dial gauges. The system can automatically pcrionn collection and treatment of the test data (calculating, showing, diagramming and so on), so that it can reduce laborious work. The test processes are clearly stated, and shown by Chinese characters and in dialog mode. The screen can show the change of parameters. All technical indices satisfy the design requirment.
