The invention relates to an online safety detection prewarning device of an elevator. The device comprises a car prewarning device and a machine room prewarning device, wherein the car prewarning device consists of a first sensing unit, a first acquiring unit, a first processing unit and a first near field communication unit; the machine room prewarning device consists of a second sensing unit, a second acquiring unit, a second processing unit and a second near field communication unit; the first near field communication unit and the second near field communication unit are in wireless communication; and the second processing unit is remotely communicated with a remote platform through a remote communication gateway. The invention further discloses an online safety detection prewarning method of the elevator. The device adopts a probability neural network algorithm; and the algorithm enables measured characteristic parameter thresholds to continuously self-learn, self-adapt and self-adjust along with such conditions as elevator ageing degree, maintenance condition and load magnitude, so that the wrong judgment or judgment missing probability is largely reduced, and the long-time use reliability and accuracy of a prewarning function of the device are improved.
