Abstract
The present invention discloses a method and an apparatus for monitoring an elevator door-opening operation fault. The method includes: acquiring elevator control signals from a serial interface between an elevator controller and a control box by using a preset data acquisition device, wherein the elevator control signals include an elevator operation signal, an elevator door control signal, an elevator internal call signal and an elevator floor signal; monitoring whether there is an elevator door fault in the elevator based on the elevator operation signal, the elevator door control signal and the elevator floor signal; when there is the elevator door fault in the elevator and the elevator internal call signal is in a preset level state, determining that there is the elevator door-opening operation fault in the elevator. The present invention is lower in use cost and may be easily popularized and applied.
