摘要
电梯运行过程中,利用加速度传感器记录电梯轿厢加速度,传感器系统不断向控制器发送速度变化信息,单片机对这些信息加以分析判断,如果所测的加速度超过阈值,则控制装置向气体发生器发出点火命令控制点火,点火后发生爆炸反应,产生N2释放出来充满气囊。乘员与气囊接触时,通过气囊上排气孔的阻尼吸收碰撞能量,达到保护乘员的目的。文中在以上基础上增加机械式触发装置,以弥补电梯电路系统故障时不能正常触发的缺陷。
When the elevator is in operation, the acceleration sensor records the acceleration of the elevator ear, and the sensor systems uninterruptedly transmits the speed change information to the control device, and the microcontroller analyzes the information. If the measured acceleration exceeds the pre-set threshold value, the control device would send an ignition command to the gas generator and react explosively after ignition. A large amount of N2 is released to congest the airbag. When the crew is in contact with the airbag, collision energy is absorbed by the vent damper airbag, thus to protect the crew. And with the addition of mechanical triggering device, the defects that the elevator circuit system fails to can＇t normal trigger could be remedied.
