Problems solved by technology

In addition, the existing voice nodes are mostly point-to-point transmission, and there are not many wireless transmission nodes that support multi-hop, especially the voice nodes that have self-organization functions and can support dynamic Mesh wireless sensor networks have not been published. Therefore, how to realize voice data in Multi-hop transmission in wireless sensor networks is also an important research topic

Abstract

The invention discloses an audio sensor board and a multihop audio transmission method. The hardware of the audio sensor board has the functions of audio codec and AD / DA switching, and is provided with a universal interface which can constitutes an audio sensor node together with a wireless sensor network core-board; by using the method, the audio codec and real-time multihop audio transmission can be realized, and the wireless communication software abides the norms of ZigBee 2006 protocol stack of TI company. The network audio node of a multimedia wireless sensor formed according to the invention can join in ZigBee network dynamically, and the audio real-time multihop long distance transmission can be realized. The invention can be used in the audio transmission or audio remote control and human-computer interaction based on audio identification / synthesis in the fields of environmental detection, rescue robots, humanoid robots, intelligent home, intelligent toys, intelligent traffic, environment monitoring, auto electronics, health supervision, military technology, and the like, and is especially applicable to the application field which supports ZigBee audio transmission.

Description

technical field [0001] The invention relates to the technical field of multimedia wireless sensor networks and the technical field of ZigBee low-speed short-distance wireless personal area network communication, in particular to an easily assembled multimedia wireless sensor network audio node and a multi-hop voice transmission method thereof. Background technique [0002] With the continuous development of multimedia technology, wireless communication technology and electronic technology, multimedia wireless sensor network technology has aroused the general concern of the society.
