基于CAN总线的语音库在线维护实现方法

Implementation Method of Sound Library Maintenance On-line Based on CAN Bus

在飞行器仪表中,经常需要以语音播报的方式向操作人员告知有关事件、预警或者报警的信息,而这些通报信息通常是以语音库的形式预先存储在仪表设备的存储介质中。但随着应用要求的不断变化,通报信息也会随之发生改变,因此,对于预先存储的语音库必定也会更改。如果能够在系统运行状态下,在线对仪表设备存储介质中的语音库进行更新,那将会给使用带来极大的方便。本文结合实际工程应用,提出一种基于CAN总线传输完成语音库在线维护的实现方法,该方法已经通过实验验证,有不错的应用价值。

In aerocraft instruments, it need to notice the operation staff something about event, early warning and warning by sound broadcast; sound library always prestore in the storage medium of aerocraft instruments. But the demand is dynamic, the sound library also to be changed. If the sound library of aerocraft instruments can be maintained on the system operation state, it will be very convenient for user. With the practical examples in engineering, the paper proposes a method which support sound li- brary maintenance on-line based on the CAN Bus. This method has been tested, and it is very valuable for practical application.
