The invention provides an emergency command audio and video transmission method. The emergency command audio and video transmission method comprises the following steps that a camera uninterruptedly shoots the internal condition of an elevator car, a microphone uninterruptedly picks up sound in the elevator car and obtains audio and video, and the audio and video are stored in a storage; when the elevator car detects that a person enters the elevator car, the weight of the person is detected, and a device detects the height of the person; according to the weight of the person and the height of the person, the obtained force acting on the elevator car when the person naturally falls down is preset force; when the person enters the elevator for a certain time and a load sensor detects that the force applied to the elevator car changes rapidly, whether the force matches with the preset force or not is judged; and if the force matches with the preset force, it is determined that an accident occurs in the elevator car, and the elevator car sends an emergency notice to a command center and sends audios and videos within a certain time before and after the accident to the command center. The emergency command audio and video transmission method and the emergency command system are simpler, more convenient and more accurate.

    本发明提供一种应急指挥音视频传输方法,包括:摄像头不间断地拍摄电梯厢内部情况以及麦克风不间断地拾取电梯厢内声音并得到音视频并将音视频存储在存储器中;当电梯厢检测到有人进入到电梯厢内时,检测人的重量以及装置检测人的身高;根据人的重量以及人的身高计算得到的人在自然摔落时作用电梯厢的力为预设力;当人已进入到电梯内一定时间后并且人已进入到电梯内一定时间后并且负载传感器检测到施加在电梯厢的力迅速变化时,判断力是否与预设力相匹配;如果力与预设力相匹配,确定电梯厢内出现意外情况,并且电梯厢向指挥中心发出紧急通知以及向指挥中心发送意外发生前后一定时间内的音视频。本发明更简便以及更准确。
