The invention relates to an anti-galloping elevator safety device. The anti-galloping elevator safety device comprises a differential sampling module circuit, a threshold monitoring circuit and a core control circuit. Firstly, the differential sampling circuit can accurately collect the running state of an elevator by utilizing the characteristics of differential signals, and low-frequency amplification processing is carried out on the signals by utilizing an operational amplifier, and meanwhile, a capacitor bank is embedded to filter out the environmental disturbance quantity. Secondly, the threshold monitoring module mainly adopts a field effect transistor and a triode which are connected in series and in parallel to judge and monitor the signal processed by the previous stage, and outputs the judged result to the next stage. Finally, the core control circuit changes the running state of the elevator according to the processing signal of the previous stage and gives alarms of different grades.
