An early warning system based on grid fault information analysis is used by monitoring workers to easily monitor a grid fault signal, and comprises a signal processing unit, an alarm unit, a scheduling control system and an integrated machine. The alarm unit comprises a base, a printer, a turntable, housings, indicator lights, a liquid crystal screen, a rotating mechanism and a translation mechanism. The printer is arranged on the base. The turntable is rotationally installed on the upper part of a vertical plate fixed to the base. The vertical plate is equipped with a rotating mechanism driving the turntable to rotate. The turntable is provided with the housings and a first locking mechanism for achieving relative fixation of the housings and the turntable. The housing is equipped with the indicator light and the liquid crystal screen. The indicator lights on the different housings can emit light with different colors. Each housing is equipped with a storage battery and a normally open switch. The storage ba
