Chapter 4 portable rotating machinery vibration monitoring system design
With the modernization of enterprise device management, how to make equipment, continuous, reliable, safe and efficient operation to meet the requirements of modern enterprise management, is particularly important. The rotating mechanical equipment during operation of the vibration signals generated a lot of hidden information that can help people to correctly judge the various types of rotating machinery during operation of the state. Theory of vibration analysis and condition monitoring technology is anisms. Based on vibration analysis of rotating machinery condition monitoring system is to run the process of rotating machinery vibration information generated by the core to determine rotating machinery is running or the anomaly occurred.
The system works
The system works: The acquisition rotating machinery vibration sensor equipment running in the process of the vibration signals, after filtering hardware circuit amplification, A / D conversion, and then upload the data through the USB interface to puter for processing; puter can be the data collector sample rate, channel selection and so the corresponding parameter settings; through the application of the software for signal analysis and processing and analysis of paint-related waveforms; and then, through the relevant waveform analysis and spectrum analysis to determine the health status of machinery and equipment.
System Structure Diagram
Design concept of this system is the top-down design, the first device to achieve the overall planning function, and then divide the total work function to the hardware and software sub-modules to realize the system overall design block diagram shown in Figure 1.
Vibration speed sensor selection
Vibration sensor (Sensor) is a collection can be generated by rotating machinery vibration signals, according to a certain law of vibration signals are converted to their corresponding ph
