The powerful database structure is adopted to manage the information of equipment measurement points, which can establish equipment files more effectively, facilitate equipment management, and improve the efficiency of equipment monitoring.Perfect system Settings, you can choose acceleration, speed, displacement of any kind of sensor, making the system suitable for a variety of field applications.

Real-time data collection and monitoring function：
■Equipment structure monitoring diagram: display the schematic diagram of the shaft series structure of the monitored unit and the corresponding position of the measuring point, and dynamically display the latest real_time data near the location of the measuring point. The color displayed reflects the operation state of the unit: green represents normal, yellow represents abnormal, and red represents danger.The system provides the shaft structure diagram and measuring point display coordinates of the steam turbine unit, water turbine unit, air compressor unit, pump unit and fan unit, and can be customized according to the actual situation of the equipment.It can reflect the state of equipment more directly and accurately.

■Bar chart: the bar chart visually shows the vibration amplitude of each channel. If the color of the bar chart is green, the vibration is normal; if yellow, the vibration value exceeds the alarm value; if red, the vibration value exceeds the tripping value.

■Time domain analysis: it displays the time domain characteristics of each channel vibration, including time domain waveform, probability density, autocorrelation analysis, cross-correlation analysis, various window functions (hanning window, hamming window, triangle window, rectangular window, etc.), real-time display of a variety of dimensional parameters (peak value, average value, effective value) and a variety of dimensionless parameters;It is easy to judge the running state of the equipment and make accurate diagnosis.

■Frequency spectrum: the frequency and amplitude of the harmonic components in the signal can be obtained by spectrum analysis of the time domain waveform.Taking frequency Hz or frequency conversion multiple as the abscissa and amplitude as the ordinate, the spectrum diagram can be obtained by plotting the analysis results on the graph.；
Spectrum diagram is the most commonly used graph for fault analysis and diagnosis, from which important information about the frequency components of signals can be obtained.The figure also shows the amplitude of the corresponding point at the specified waveform.The spectrum categories include amplitude spectrum, power spectrum, phase spectrum, cepstrum analysis, etc., and six maximum spectral peaks and corresponding frequencies are displayed in real time, and various window functions are optional.Linear and logarithmic spectrum selection, used for the analysis of the common faults of various rotating machines, such as unbalance, misalignment, shaft bending and shaft crack；
■Average spectrum analysis: in order to effectively eliminate the field interference signal, the average spectrum in time domain and frequency domain can be used to improve the signal-to-noise ratio.
■Axis trajectory diagram: corresponding to a certain speed, the position of the rotating shaft in the supporting bearing is certain.Due to the vibration, the center of the rotating axis will move around the center point periodically, forming a dynamic trajectory, that is, an axis trajectory diagram.This figure shows the situation after the horizontal and vertical vibration synthesis of a bearing. Different corresponding faults will present different shape axis trajectories. Therefore, fault diagnosis can be conducted through axis trajectories；
■Wave chart: it shows the vibration amplitude of the unit in the start-up and shutdown process and it shows the vibration amplitude and phase of the unit in the start-up and shutdown process with the change trend of the speed.The baud diagram is an important tool for determining the critical speed. If the amplitude curve has a wave peak and the phase increases sharply at the same time, and the increase is greater than 70 o, then the corresponding speed may be the critical speed of the rotor where the measuring point is located or adjacent to the rotor.

The amplitude and phase changes observed from the baud diagram along with the rotation speed can be used to analyze the axial position of the unbalanced mass of the rotor, the order of the unbalanced vibration type, the existence of structural resonance, and the analysis of dynamic and static friction.
■Polar graph: also known as Nyquist graph, it shows the change of vector end of the octave vector with the rotation speed in the start and stop process of the unit in vector form, its radial diameter represents the magnitude of the octave amplitude, the included Angle between the radial diameter and the X_axis represents the phase of the octave, and the lower part of the graph can show the corresponding rotation speed, amplitude and phase at the specified waveform.

■The amplitude-speed curve appears as a ring in the polar graph, from which it is easy to obtain the parameters of each mode.

■3 d spectrum: it shows the variation trend of the size of various frequency components with the speed in the process of starting and stopping at different speeds. It is a 3 d spectrum diagram successively composed of the spectrum diagrams obtained at different speeds, which has the function of graph scaling.Through the three-dimensional spectrum, we can see whether there are abnormal frequencies (low and high frequency components), whether there are fixed frequencies, as well as the rotating speed, amplitude size and changes when they occur, from which we can know the operating state of the unit and provide important information for the diagnosis of some faults.It is very intuitive to use cascade diagram to analyze the faults related to amplitude and speed. The most typical faults of this kind are oil film eddy and oil film oscillation.

■Relevant trend diagram: it shows a certain period of time signals (fengfeng value, double frequency vibration amplitude, phase, speed, time), the change of the relationship between each other, the abscissa and ordinate of the freedom of choice by the user on the analysis of the vibration parameters (condition) over time, the change of rotating speed, load, the curve is intuitive, is very useful to running situation personnel monitoring unit.
