摘要
针对常规液压拉力实验机存在的不足,研制了以PLC和上位机为控制核心的钢丝绳拉力机测控系统。详细介绍了磁致伸缩位移传感器的原理、特点及其与S7-300PLC的接口方法。给出了2000kN钢丝绳拉力机测控系统的结构框图和软件流程图。应用结果表明:此系统工作稳定可靠、监测精度高、维护简单,极具行业推广价值。
The principles and characteristics of the magnetostrictive displacement sensor is introduced, and the application of the 2000kN steel cable pulling-force monitoring system based the MTS magnetostrictive displacement sensors and the S7-300 Plc is describled. The application result shows that,This system work stable reliable, the monitor precision high, the maintenance is simple, has the profession promotion value extremely.
