The invention discloses a monitoring method and device for the failure of elevator collapsing to the bottom of pit and rushing up to the top. The method comprises the steps that preset data acquisition equipment is used, the elevator control signal is collected from the serial interface between an elevator controller and a operational control box, whether an elevator runs to the bottom layer or the top layer is monitored based on the elevator floor signal, and the working state of the elevator is monitored based on the elevator operation signal; when the fact that the elevator runs to the bottom layer is monitored, if the working state of the elevator is operating state, the continuous time of the running state is greater than the preset time threshold value, the failure of elevator collapsing to the bottom of pit is determined, when the fact that the elevator runs to the top layer is monitored, if the working status of the elevator is running state, the continuous time of the runningstate is greater than the preset time threshold value, and the failure of elevator rushing up to the top is determined. The monitoring method does not need to install an elevator position detector additionally, the failure of elevator collapsing to the bottom of pit and rushing up to the top can be detected, and the use cost is lower.
Description
technical field [0001] The invention relates to the technical field of elevator safety, in particular to a method and device for monitoring elevator squatting and topping faults. Background technique [0002] Elevators are the main equipment for users to travel in high-rise buildings. The setting of elevators provides great convenience for people's travel. It is an important factor affecting the safety of elevator riding. How to discover the failure of the elevator at the bottom and the top at the first time, so as to deal with it in time (emergency repair), has become an important research topic. [0003] At present, in order to timely detect the failure of the elevator at the bottom and the top, and reduce the loss caused by the failure of the elevator, it is usually to add an elevator position detector in the elevator room to monitor the position of the elevator, but the installation process of the elevator position detector is complicated, and the installation cost Hig...
