The present invention relates to a coal mine ventilator real-time fault diagnosis and early warning device based on a virtual instrument development platform (LabVIEW), including an integrated industrial computer, a vibration signal detection module, an ARM processor, a stabilized power supply module, an SD storage module, and a USB interface chip. The vibration signal detection module processes the detected vibration signal and transmits it to the A / D analog-to-digital converter of the ARM processor, and the ARM processor transmits the processed digital signal to the integrated industrial computer through the USB interface chip or stores it in the SD storage module . The LabVIEW platform of the integrated industrial computer calls the algorithm program in MATLAB through the MatlabScript node, and performs wavelet denoising filtering, CEEMDAN feature extraction, Hilbert transform, and improved support vector machine classification and recognition on the fan vibration signal transmitted to the industrial computer. , the final result of fault diagnosis is displayed on the front panel interface, and the early warning module is called to sound and light alarm for fault information, and sound and light early warning for hidden faults. The device has good real-time performance, high openness, friendly man-machine interface and high reliability.
