Pressure sensor acquisition system based on big data

Abstract

The invention discloses a pressure sensor acquisition system based on big data, which belongs to the technical field of pressure sensor acquisition and comprises a correction module, a data acquisition module and a server. The correction module is used for correcting the influence of the environment temperature on pressure collection of the pressure sensors. The specific method comprises the steps of SA1, acquiring the models of the pressure sensors, and acquiring pressure values of multiple sets of pressure sensors of the corresponding models at different temperatures from the Internet according to the models of the pressure sensors, marking a plurality of groups of detected pressure values at different temperatures as simulation values, and SA2, establishing a temperature curve model, inputting the simulation value into the temperature curve model to obtain a pressure sensor temperature curve. The temperature curve model is established, the simulation value is input into the temperature curve model, the temperature curve of the pressure sensor is obtained, and the influence of different temperatures on pressure acquisition can be accurately known according to the obtained temperature curve of the pressure sensor.

Description

technical field [0001] The invention belongs to the technical field of pressure sensor acquisition, in particular to a pressure sensor acquisition system based on big data. Background technique [0002] Pressure sensor is the most commonly used sensor in industrial practice. Generally, the output of ordinary pressure sensor is an analog signal. The feature quantity representing information can be presented as a signal of any value at any moment. The pressure sensors we usually use are mainly manufactured using the piezoelectric effect, and such sensors are also called piezoelectric sensors. [0003] At present, the pressure values ​​collected by most pressure sensors are not correct values, because the pressure sensors will be affected by the ambient temperature when measuring, resulting in inaccurate measurement results. In some industries that require accurate measurement, untrue measurement The value may cause greater safety hazards and economic losses, as shown in Tabl...

[0003] At present, the pressure values ​​collected by most pressure sensors are not correct values, because the pressure sensors will be affected by the ambient temperature when measuring, resulting in inaccurate measurement results. In some industries that require accurate measurement, untrue measurement The value may cause greater safety hazards and economic losses, as shown in Table 1, the impact on pressure sensor acquisition at different temperatures; therefore, it is necessary to eliminate the impact of temperature on pressure sensor data acquisition by setting a correction module
