针对传统的液压电梯检测方法落后、精度不高、速度慢,基于单线程的测控软件实时性、稳定性差等问题,本文以单片机和相应传感器为硬件基础,利用Lab Windows/CVI的多线程技术,设计了液压电梯状态检测系统。该系统能够实现数据采集、信号滤波、数据分析和存储。测试结果表明,该检测系统实时性和稳定性高,为液压电梯的安全运行提供了可靠保障。 Aiming at the problems of traditional hydraulic elevator detection methods such as backwardness, low precision and slow speed, based on single-thread measurement and control software, such as real-time and poor stability, this paper based on hardware of MCU and corresponding sensors, Design of hydraulic lift status detection system. The system enables data acquisition, signal filtering, data analysis and storage. The test results show that the detection system has high real-time and high stability, which provides a reliable guarantee for the safe operation of the hydraulic elevator.
