摘要
为实现静力试验自动化,提高试验精度和稳定性,提出了一种静力试验自动化控制方法。采用高频率、高精度A/D模块采集压力信号,以可编程逻辑控制器(PLC)为下位机控制液压系统,以计算机为上位机,集控制系统、测量系统与数据存储系统为一体,实现了静力试验自动化。试验结果表明,该系统可实现对静力试验的高效、精确控制。
Aiming at achieving static test automation and improving test accuracy and stability,an automatic static test method was proposed. A/D module with high frequency and high precision was applied to collect signal of oil pressure sensor, and hydraulic system was controlled by programmable logic controller （PLC）,which was used for lower computer. Upper computer set control system, system and data storage system as a whole,the static test automation was realized. The test results indicate that the system can make efficient and precise static test.
