Abstract: 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.
