The invention provides a car overspeed monitoring device of an elevator and a car overspeed monitoring system of the elevator, which can be provided with a mechanism for releasing the stopped state of the car under the condition that the structure is not complicated. The elevator car overspeed monitoring device is provided with an overspeed detection part which uses a signal output by a position detector arranged in an elevator shaft to create information representing the position of an elevator car, the information indicating the position of the car and the information indicating the speed of the car are used to detect an overspeed state in which the speed of the car is faster than a predetermined speed corresponding to the position of the car. A stop control unit that causes the car to be stopped when the overspeed detection unit detects the overspeed state of the car; and a stopping release unit that causes the stopping control unit to release the state in which the car is stopped when a change in the state of the signal output from the position detector is detected in a state in which the car is stopped by the stopping control unit.

    提供能够在不使结构复杂的情况下设置解除轿厢被制止的状态的机构的电梯的轿厢超速监视装置以及电梯的轿厢超速监视系统。电梯的轿厢超速监视装置具备:超速检测部,其使用从设置于电梯井道的位置检测器输出的信号来创建表示电梯轿厢的位置的信息,并使用表示轿厢位置的信息和表示轿厢速度的信息来检测处于轿厢的速度比与轿厢位置相应的规定速度快的超速状态的情况;制止控制部,其在超速检测部检测到轿厢的超速状态的情况下,使得成为轿厢被制止的状态;以及制止解除部,其在通过制止控制部制止了轿厢的状态下检测到从位置检测器输出的信号的状态发生了变化的情况下,使制止控制部解除轿厢被制止的状态。
