Adaptive filtering universal data acquisition system based on labview

The invention discloses an adaptive filtering universal data acquisition system based on labview. The invention discloses a labview-based self-adaptive filtering universal data acquisition system, comprising a data acquisition module, a controller module and a data processing module. The data acquisition module comprises a sensor with a communication protocol, a hardware interface, a sensor without a communication protocol and an analog-to-digital conversion part. A sensor with a fixed communication protocol is directly connected with the hardware interface part; The hardware interface part isused for making interfaces for different communication protocols. A sensor without a communication protocol characterizes a physical change by a voltage change, and an analog-to-digital conversion section converts an analog quantity of the voltage change into a digital quantity. The device has the advantages that various data interfaces are provided for the sensor with the communication protocol,a high-precision analog-t
