摘要
为保证矿井提升机液压制动系统安全可靠运行,针对制动性能参数检测实时性差、开贴闸点检测不精确问题,结合LabVIEW的数据采集优势和MATLAB的数据处理能力,设计了基于LabVIEW的液压制动系统监测装置。通过在制动器闸瓦上安装非接触位移传感器,在液压油路上安装油压传感器,利用LabVIEW编程内嵌调用MATLAB数据处理,实现对制动系统运行状态的实时监测,及时发现和排除故障隐患,确保液压制动系统安全可靠运行。现场应用表明,该装置具有实时性好、测量精度高的优点,具有较高的实用价值。
Aiming at poor real-time performance of braking performance parameter detection and inaccurate detection of open and close gates,designed a monitoring device of hydraulic brake system based on LabVIEW and MATLAB. It combined the advantages of data acquisition in LabVIEW and the data processing capabilities of MATLAB to ensure safe and reliable operation of the mine hoist hydraulic brake system. Firstly, a non-contact displacement sensor was installed on the brake shoe, and a hydraulic pressure sensor was installed on the hydraulic oil line. Then, the designed LabVIEW program was used to read the sensors' data in real time, and the MATLAB was called in the LabVIEW program to process the data. In this way, the real-time monitoring of the brake system operating state can be realized, and find and troubleshoot in time to ensure safe and reliable operation of the hydraulic brake system. The field application showed that the designed device has the advantages of good realtime performance and high measurement accuracy, and it has practical value.
