The invention discloses an intelligent safety detection system for an elevator. In the system, a first detection module is used for detecting whether an elevator overspeeds or overloads, whether a steel wire rope slips or not and whether the average air pressure in an elevator car in a set time period exceeds standard air pressure or not; the second detection module is used for detecting whether the difference value between the parameter of each elevator driving assembly and the corresponding rated data exceeds a set range or not; the parameters comprise a voltage value and a current value; the third detection module is used for acquiring an image of an object in the elevator car when an elevator car door is opened, processing and comparing the image with a pre-stored sample image, and intelligently judging whether an electric vehicle enters the elevator car or not; the controller is used for controlling the elevator brake according to detection results of the three detection modules. Intelligent safety detection is carried out on the elevator from multiple aspects, and the elevator running safety is improved.
本发明公开了一种电梯智能安全检测系统。该系统中,第一检测模块用于检测电梯是否超速、电梯是否超载、钢丝绳是否打滑和设定时间段内电梯轿厢内平均气压是否超出标准气压;第二检测模块用于检测各电梯驱动组件的参数与对应的额定数据的差值是否超出设定范围;参数包括电压值和电流值;第三检测模块用于在电梯轿厢门打开时,获取电梯轿厢内物体的图像,并将图像与预先存储的样本图像进行处理、比对,智能判断是否有电动车进入电梯轿厢;控制器用于根据三个检测模块的检测结果控制电梯制动器。本发明从多个方面对电梯进行智能安全检测,提高了电梯运行的安全性。
