The invention discloses an elevator terminal emergency deceleration system, which is characterized in that a car speed position threshold curve is constructed above a current car speed position curve, that is, areas of elevator car speed below the car speed position threshold curve are all safe areas, and a controller cannot control an elevator car traction machine to brake emergently; and when the current speed of the lift car is greater than the current position threshold speed, the controller immediately controls the elevator lift car traction machine to brake emergently. According to the elevator terminal emergency deceleration system, abnormal speed of the elevator car can be effectively detected in real time, braking deceleration can be carried out in time, it can be guaranteed that the elevator car does not exceed the preset speed in the descending process, compared with a traditional mechanical arrangement reference position switch, the depth of a pit can be shortened to the maximum extent, and safety is improved. The problem that the depth of a well pit needed by an ultra-high-speed elevator is too large can be effectively solved, the suitability of the elevator is improved, and the elevator is more competitive in the market.

    本发明公开了一种电梯终端紧急减速系统,在当前轿厢速度位置曲线上方构造一条轿厢速度位置阈值曲线,即电梯轿厢速度在该轿厢速度位置阈值曲线以下的区域均为安全区域,控制器不会控制电梯轿厢曳引机紧急制动;当轿厢的当前速度大于当前位置阈值速度,控制器则立即控制电梯轿厢曳引机紧急制动。该电梯终端紧急减速系统,可以实时有效的觉察轿厢速度异常,并及时进行制动减速,能够保证轿厢在下降过程中不会超过预定的速度,相比于传统机械式设置基准位置开关,可以最大程度缩短底坑的深度,可有效应对超高速电梯所需井道底坑深度过大的问题,提高电梯的适配性,使得电梯在市场中更具竞争力。
