油缸实时检测系统控制策略研究

针对现有油缸检测系统检测手段和技术落后及检测精度低等缺点，提出把测试项目模块化后，将模块有机组织在液压缸运行过程中来完成油缸检测的控制策略。运用PLC(programmable logic controller,可编程控制器)控制、CoDeSys组态软件和Visual Basic 6.0技术设计了一套油缸实时检测系统。试验结果表明，新的测试系统实现了实时检测、试验数据和曲线以及试验报告的输出和打印，提高了检测效率。

Research on control strategy of real-time testing system for hydraulic cylinder

Aiming at the disadvantage of traditional hydraulic cylinder testing system, such as old measure, low detection precision, etc.,a new control-strategy to checkout property of tested cylinder was proposed. The new strategy succeeded to modularize the tested property and organically combine tested properties of cylinder together during hydraulic cylinder moving. The new real-time testing system made use of the technic of PLC(programmable logic controller), CoDeSys configuration and Visual Basic 6.0. The test results indicated that the real-time testing system made hydraulic cylinder properties be inspected successfully; test data and curve could be printed out, and increased testing efficiency.
