Method, device and system for monitoring operation of cockpit

The invention discloses a method, a device and a system for monitoring operation of a cockpit. The monitoring method comprises the following steps: acquiring voice data in a cockpit; converting the voice data into text data; receiving flight phase parameters from the onboard control system; dividing the text data into text data segments by time based at least in part on the flight phase parameter; and identifying cockpit operations associated with the respective flight phases based at least in part on the text data segments. The monitoring device comprises a voice acquisition module, a voice recognition and processing module, a text processing module and the like which are used for executing each step of the monitoring method. Numerous other aspects are also described. 本申请描述了一种用于对驾驶舱操作进行监测的方法、装置和系统。其中，监测方法包括：采集驾驶舱中的语音数据；将该语音数据转换成文本数据；从机载控制系统接收飞行阶段参数；至少部分地基于该飞行阶段参数来将该文本数据按时间划分成文本数据区段；以及至少部分地基于该文本数据区段来识别与相应飞行阶段相关联的驾驶舱操作。监测装置包括用于执行监测方法的各个步骤的语音采集模块、语音识别和处理模块、文本处理模块等。还描述了众多其他方面。
