The invention relates to a mining elevator gearbox hidden danger identification method and a monitoring device, and belongs to the field of automation. Axial and radial vibration acceleration signals of a mining elevator gearbox are collected for digital filtering, FFT conversion is carried out after analysis processing, frequency domain vibration amplitude is calculated after Hanning window filtering, according to the working rotating speeds and basic parameters of a bearing and a gear of the mining elevator and the width of a frequency domain spectral line, bearing hidden dangers and gear hidden dangers are identified through comprehensive analysis by taking X1, X2 and X3 frequency multiplication in a frequency domain as vibration amplitudes in a central frequency band, and early warning and alarm output are carried out after set threshold values are reached, wherein parameters can be configured by an upper computer. The monitoring device is mainly composed of a signal conditioning module, a high-precision AD module, an FPGA, an RS485 interface module, an Ethernet interface module, an LED display module and an output module. The monitoring device communicates with the upper computer through the Ethernet, and transmits vibration acceleration, vibration amplitude, hidden danger recognition results and parameters.
