基于WSN兼有语音通信的矿井安全监控系统研究

Study on Mine Safety Monitoring System with Emergency Voice Communication Based on Wireless Sensor Network

摘要: 针对目前井下语音通信的现状，提出了基于无线传感器网络兼有应急语音通信功能的实时环境监控系统，该系统以Stargate和Imote2开发板为核心设计传感器节点，并对系统体系结构、软硬件设计以及具有优先级语音和井下环境监测调度算法进行了研究。实验表明，该系统简单、可靠、经济，同时并兼顾井下语音通信和环境监控的实时性、公平性。

Abstract: In view of the current status of voice communications in mine, a design method of real time envi-ronment monitoring system which can also transmit an emergency voice based on wireless sensor network is proposed. The sensor node of the system is mainly designed by Stargate and Imote2 development board, and its architecture, hardware and software design, scheduler algorithms between environment monitoring multi-tasks and audio task with priority are studied. The ex-periment shows that the system is simple, reliable, economic and gives consideration to the re-al-time, fair of audio and safety monitoring in mine.
