The invention discloses a passenger elevator with an automatic silencing car, which overcomes the problems that the silencing effect of an elevator silencing device in the prior art is influenced by time, and whether the silencing device fails or not cannot be detected, and comprises a noise acquisition device, a control system, an automatic silencing device, a control system and an automatic silencing device, and is characterized in that the noise acquisition device is used for acquiring a sound signal of elevator noise and sending the sound signal to the control system; the control system is used for carrying out frequency domain transformation on the collected sound signal of the elevator noise to obtain the elevator noise frequency, sending a control signal to the silencing device and judging whether the silencing device breaks down or not; the silencing device is used for receiving the control signal sent by the control system, sending out silencing frequency, counteracting noise frequency and realizing silencing; the monitoring device is used for monitoring whether the silencing device breaks down or not and sending monitoring data to the control system. Noise generated during operation of the elevator can be eliminated, and the use feeling of passengers is improved.

    本发明公开了一种带自动消音轿厢的乘客电梯,克服现有技术中电梯消音装置消音效果受时间影响、且无法检测消音装置是否故障的问题,包括:噪音采集装置,用于采集电梯噪音的声音信号并发送给控制系统;控制系统,用于对采集到的电梯噪音的声音信号进行频域变换,得到电梯噪音频率,发送控制信号给消音装置,并判断消音装置是否故障;消音装置,用于接收控制系统发出的控制信号,发出消音频率,抵消噪音频率,实现消音;监测装置,用于监测消音装置是否发生故障,并发送监测数据给控制系统。能够消除电梯运行中产生的噪声,提高乘客使用感。
