工程机械液压系统故障快速检测仪的设计

Design of Hydraulic System Fault Detection Equipment for Construction Machinery

论文介绍了一种工程装备液压系统状态检测诊断系统。该检测仪由硬件和软件两部分组成,硬件部分包括ECM-945GSE工控机、基于ARM芯片的嵌入式数据采集系统、液晶屏、触摸屏、电源模块和传感器等。软件系统主要包括数据采集程序、故障诊断和检测主程序、输出打印程序等。现场的试用试验表明,该设备能够快速方便地检测诊断液压系统的故障,提高工程机械检测与维修保障的效率。

To the characteristic of vibration, dust and serious electromagnetic disturbance in the construction machinery condition, we made the portable fault detection equipment for the construction machinery hydraulic system. The equipment mainly consists of hardware and soft- ware. The part of hardware includes the core control unit ECM-945GSE industrial computer, 8-channel data acquisition module based on ARM chip, LCD screen, touch screen, power module, PTT pressure measurement sensors, as well as the integration of temperature, pressure, flow measurement sensors and equipment cabinet and so on. The software system mainly includes data acquisition procedures, diagnosis, de- tection and output printing programs and drivers programs. The pilot trial in the armed forces shows that both detectors can be used in repair shop or indoor, but also in the field of construction machinery on-site emergency repair when rapid detection and diagnosis. And it has a strong adaptability.
