摘　　要：高压隔膜泵是矿浆管道输送系统的动力源,随着无人值守泵站的投入运行,如何远程监测高压隔膜泵的运行状态就成为亟需解决的问题。文中设计了一种基于STM32的高压隔膜泵运行状态远程监测系统。该系统实时采集单向阀振动信号,将采集到的振动信号数据通过以太网传输到远程服务器中,在服务器中采用固有时间尺度分解方法(ITD),对高压隔膜泵单向阀振动信号进行分析,从而实现对高压隔膜泵运行状态的远程监测。实验结果表明,该系统采集信息准确,传输速度快速且稳定,可以在工业行业推广使用。High-pressure diaphragm pump is the power source of slurry pipeline transportation system.With the operation of unattended pump station,it is urgent for us to solve the problem that how to monitor the operation of high-pressure diaphragm pump remotely.In order to do this,the paper States a design of a remote monitoring system based on STM32.This system collects the one-way valve vibration signal in real-time,after that,it transmits the collected vibration signal data to the remote server through Ethernet.In the server,this system adopts the Intrinsic Time scale Decomposition(ITD)method.Finally,it analyzes the vibration signal of the check valve of the high pressure diaphragm pump.This is the process of remote monitoring for the high-pressure diaphragm pump running status.The experimental results show that in this system,the collection of information is accurate,the transmission speed is fast and stable,so we can conclude that this system is highly recommend to be used in the industrial sector.
