The invention discloses an anti-collision safety
early warning system for an
elevator landing door. The
system comprises a mounting rack which is arranged on the front side of the landing door, the mounting rack is composed of a top rod, a left-side rod and a right-side rod, the top rod is provided with a landing door opening detection device used for detecting whether the
elevator landing door isopened or not, and the opposite positions of the left-side rod and the right-side rod are provided with article existence and absence detection device used for detecting whether an article exist in front of the landing door or not; the
system further comprises a control module and an alarm lamp, the landing door opening detection device, the article existence and absence detection device and thealarm lamp are connected with the control module correspondingly. According to the
system, the
signal is more accurate, the situation that a person easily triggers the system to cause
false alarm whenthe person walks in a passageway can be avoided to the maximum degree, moreover, the influence caused by the temperature of a detected article and the temperature of the ambient environment is avoided, meanwhile, an active anti-collision intercepting device is installed, the
impact risk is reduced to the largest extent through active intercepting, moreover, the system is completely independent and makes no contact with the
control system of an
elevator, so that no influence is caused to the elevator.
