The invention discloses an elevator car door induction system based on pressure induction, and relates to the technical field of elevator safety, the induction system comprises two pressure sensors working independently, one pressure sensor is installed at the bottom center of a door closing position in an elevator car, and the other pressure sensor is installed at the bottom center of a door closing position in the elevator car. The other pressure sensor is mounted in the center of the top of a door closing position in the elevator car; the two pressure sensors are both in communication connection with a control module, the control module controls the elevator to stop running when the pressure of any one pressure sensor changes, and particularly for transparent objects with weights and pets with traction ropes, the problem that the objects and the elevator are damaged due to the fact that the elevator cannot sense foreign matter when a door is blocked by the transparent objects is solved; and the problem that the pet rope is clamped between the elevator doors and cannot be sensed, so that the pet is dragged and killed by the running elevator is solved.

    本发明公开了一种基于压力感应的电梯轿门感应系统,涉及电梯安全技术领域,该感应系统包括两个独立工作的压力传感器,其中一个压力传感器安装在电梯轿厢内部关门位置的底部中心处,另一个压力传感器安装在电梯轿厢内部关门位置的顶部中心处;两个压力传感器均通信连接有控制模块,控制模块在任意一个压力传感器压力产生变化时控制电梯停止运行,尤其是针对有重量的透明物体以及带有牵引绳的宠物,解决了透明物体挡门时电梯无法感知异物造成物体及电梯损坏的问题,还解决了宠物绳夹在电梯门之间无法被感应导致宠物被运行的电梯拖拉致死的问题。
