The invention discloses an elevator safety monitoring and pre-warning system. The elevator safety monitoring and pre-warning system comprises an elevator safety monitoring box and an elevator safety publicity box. A universal holder is installed at the top of the elevator safety monitoring box. A CMOS camera is installed on the universal holder. The elevator safety publicity box is internally provided with an MP3 player, a microphone and a power adapter. The outer surface of the elevator safety publicity box is provided with grids. The elevator safety monitoring box is internally provided with an elevator safety monitoring circuit board. An elevator safety monitoring circuit is integrated in the elevator safety monitoring circuit board and comprises a digital signal processor (DSP), a power supply battery, a crystal oscillator circuit, a reset circuit, a Flash data storage unit, a clock circuit module, an ultrasonic distance measurement sensor, a buzzer warning circuit, an LED flash lamp and a relay, wherein the relay is in series connection in a power supply circuit, supplying power to the MP3 player, of the power adapter. The elevator safety monitoring and pre-warning system is convenient to install and use, high in work reliability and capable of enhancing safety performance of an elevator.
