It also has the function of recording pressure state parameters to achieve data visualization.
末端气压传感器符合探测灵敏度要求，其参数设置为：压力测量范围起始值0bar，压力测量范围结束值10bar，最大过载压力15bar。The terminal air pressure sensor meets the detection sensitivity requirements, and its parameters are set as: pressure measurement range starting value 0bar, pressure measurement range end value 10bar, maximum overload pressure 15bar.
数据传输通过采集气源系统气源端与用气端压力状态参量，并将采集到的数据传输到上位监控软件中，数据传输稳定可靠。Data transmission is achieved by collecting pressure state parameters at the gas source end and the gas using end of the gas source system, and transmitting the collected data to the upper monitoring software. The data transmission is stable and reliable.
上位监控软件其界面包括一致的导航、布局、颜色、字体、图标元素，在按钮按下后具有实时的状态变化、加载状态的指示和错误提示。The upper-level monitoring software has an interface that includes consistent navigation, layout, colors, fonts, and icon elements, with real-time status changes, loading status indications, and error prompts after a button is pressed.
即上位监控软件界面具有以下特征：(1)一致性：界面保持一致性，使用户在不同页面和功能之间能够轻松理解和使用，具体包括一致的导航、布局、颜色、字体和图标等元素的使用；That is, the upper-level monitoring software interface has the following characteristics: (1) Consistency: The interface is consistent, allowing users to easily understand and use it between different pages and functions, including the use of consistent navigation, layout, color, font, and icon elements;

压力传感器采用SPAU-P10R-H-G18FD-L-PNLK-PNVBA-M12U型号。对于多气源监测点，传感器采集气压数据并非完全独立，而是具有相关性；此外，传感器会发生漂移现象，采样得到的数据便会缓慢的产生偏移，因此基于多气压传感器数据融合对整个线库气源进行监测与判定，其中对气源数据的处理至关重要，气压表在测量过程中不可避免的收到干扰，为了防止或减少干扰信号对测量结果的影响，需要对测量结果进行滤波处理，提高测量精度，同时保证测量的可靠性和稳定性；The pressure sensor adopts the SPAU-P10R-H-G18FD-L-PNLK-PNVBA-M12U model. For multiple gas source monitoring points, the air pressure data collected by the sensor is not completely independent, but correlated; in addition, the sensor will drift, and the sampled data will slowly offset. Therefore, the entire line library gas source is monitored and determined based on the multi-pressure sensor data fusion. The processing of the gas source data is crucial. The barometer will inevitably receive interference during the measurement process. In order to prevent or reduce the influence of interference signals on the measurement results, the measurement results need to be filtered to improve the measurement accuracy and ensure the reliability and stability of the measurement.
首先，采用加权滤波消除随机噪声干扰：对于离散系统，First, weighted filtering is used to eliminate random noise interference: For discrete systems,
t＝nΔt(n＝-M,＝M+1,…0,1,…,M)，加权函数为：t＝nΔt(n＝-M,＝M+1,…0,1,…,M), the weighting function is:
其中n为离散点数量，xi为离散点i处离散值，hk为加权系数，yn为加权函数；Where n is the number of discrete points,xi is the discrete value at discrete point i,hk is the weighting coefficient, andyn is the weighting function;
对加权函数归一化处理：Normalize the weighting function:
通过对权值hk取值使之呈正态形有效消除随机噪声影响；By making the weighthk into a normal shape, the influence of random noise can be effectively eliminated;
其次，采用去极值平均滤波消除脉冲干扰：Secondly, the de-extreme average filter is used to eliminate pulse interference:
对采集到的N个数据进行排队并采用滑差间隔为1的数据集进行计算，其中对每N个数据的数据集去掉最大值和最小值并计算余下N-2个数据，若N个数据排序有：The N collected data are queued and calculated using a data set with a slip interval of 1. The maximum and minimum values of each N data set are removed and the remaining N-2 data are calculated. If the N data are sorted as follows:
则yn有效消除消除脉冲干扰。Then yn effectively eliminates the pulse interference.

还包括组装I/O电缆，适用于SINAMICS V90 PROFINE，采用6SL3260-4MA00-1VB0型号。Also included is an assembled I/O cable for SINAMICS V90 PROFINE, type 6SL3260-4MA00-1VB0.
线库气源在线监控装置使用环境湿度：5％～95％，满足室内环境要求。The operating environment humidity of the line warehouse air source online monitoring device is 5% to 95%, which meets the indoor environment requirements.
由上可知，该线库气源在线监控系统能够实时监测气源系统的气源端与用气端的压力状态参量，确保气源系统的正常运行；其监控软件能够记录压力状态参量数据并实现数据可视化，方便用户直观地了解气源系统的运行状态，还可存储压力数据，方便用户查询过往的压力数据，为后续设备状态分析及用气分析提供数据支撑；根据末端用气设备的气压阈值，监控软件可根据实时运行状态发出预警，为后续的维护保养提供依据。From the above, it can be seen that the online monitoring system of the line gas source can monitor the pressure state parameters of the gas source end and the gas-using end of the gas source system in real time to ensure the normal operation of the gas source system; its monitoring software can record the pressure state parameter data and realize data visualization, so that users can intuitively understand the operating status of the gas source system, and can also store pressure data to facilitate users to query past pressure data, providing data support for subsequent equipment status analysis and gas usage analysis; according to the gas pressure threshold of the terminal gas-using equipment, the monitoring software can issue an early warning based on the real-time operating status, providing a basis for subsequent maintenance.
