The invention discloses an elevator stop device. The elevator stop device comprises a charge amplifier, a wireless communication module, a control module, a lifting drive circuit, a lifting motor as well as an elevator button and a detecting pedal arranged in front of an elevator door at each layer, wherein a groove is arranged in each detecting pedal, and a U-shaped piezoelectric film cable is arranged in each groove; the U-shaped piezoelectric films, the charge amplifier, the wireless communication module, the control module, the lifting drive circuit and the lifting motor are sequentially connected; the elevator buttons are connected with the wireless communication module; and the charge amplifier comprises a first operational amplifier, a second operational amplifier, first to ninth resistors, a first slide rheostat, a second slide rheostat and first to third capacitors. According to the elevator stop device disclosed by the invention, when the elevator buttons are pressed down and people wait on the detecting pedals all the time, the elevator decelerates, stops and opens. The elevator stop device saves time of others, and improves using efficiency of an elevator.
