基于MCGS的全液压转向器检测台电气控制系统的监测

Electrical Control System of Test Bed Based on MCGS for Hydraulic Redirectors

工程机械的工作环境一般都比较差,转向较为频繁,因此对转向器的转向性能要求很高,可以说工程机械转向器的好坏直接决定了该机械性能的优劣。在全液压转向器检测台的控制系统中,以三菱FX2N型PLC作为控制系统的核心,以MCGS工控组态软件作为可视操作界面和PLC数据的最终处理工具。利用MCGS可实时显示和复现各测试块的特性曲线,同时对全液压转向器的特性实时监测并作出最终判断。

The working environment of the engineering macbines is generally worse ,and steering operation is frequent, so the quality of the hydraulic redirectors directly affects the driving behavior of machines. The paper designs the electrical control system of a test bed for full hydraulic redirectors, which uses the PLC of Mitsubishi FX2N as the centre of the system and applies the industrial configuration software MCGS to deal with the data of PLC. The MCGS configuration software can on-line display and replay the characteristic curves of test blocks, meanwhile it can make a final decision for each experiment.
