The invention discloses an elevator traction medium safety monitoring system and method. A ring frame is arranged at an opening of a machine room ground, a broken wire and broken strand monitoring device is arranged on the ring frame, and the ring frame is detachably fixed on the machine room ground by adopting a bolt; the broken wire and broken strand monitoring device comprises a Hall sensor, anelectromagnet, a data acquisition module and a data processing module, wherein the electromagnet is used for generating a magnetic field to magnetize a monitored traction medium to magnetic saturation, the hall sensor receives a leakage magnetic field, caused by broken wires and broken strands, generated by the monitored traction medium and generates an electric signal, the data acquisition module receives the electric signal sent by the Hall sensor and transmits data to the data processing module, and the data processing module analyzes the electric signal, judges the magnetic leakage numerical value of the monitored traction medium, and transmits a fault signal to a main control panel of an elevator when the magnetic leakage exceeds a set value. According to the system and method, automatic monitoring is carried out in the operation process of the elevator, so that the monitoring and maintenance of the elevator traction medium are facilitated.
本发明公开了一种电梯曳引媒介安全监测系统及方法,在机房地面的开口处安装有圈框,圈框上安装有断丝断股监测装置,且采用螺栓可拆卸固定于机房地面,断丝断股监测装置包括霍尔传感器、电磁铁、数据采集模块、数据处理模块,电磁铁用于产生磁场,将被测曳引媒介磁化至磁饱和,霍尔传感器接收被测曳引媒介由于断丝断股而产生的漏磁场,并产生电信号,数据采集模块接收霍尔传感器发出的电信号,并将数据传输至数据处理模块,数据处理模块对电信号进行分析,判断被测曳引媒介的漏磁数值,且在漏磁超出设定值时向电梯主控制板传输故障信号。本发明在电梯运行过程中进行自动监测,方便对电梯曳引媒介的监测和维保。
