摘　　要：煤矿井下的环境复杂,通信方式和通信范围受应用场景的约束性较大,在煤矿安全生产中引入无线多媒体传感器网络技术(WMSN)可以提高安全生产监管效率,在突发事件中为应急救援工作提供有力的信息指导。为此基于DISCOVER分布式视频编码(DVC)方案,设计了以S3C6410为主处理器芯片的视频传感器节点。给出了节点的硬件框图以及软件流程图。测试表明,该节点运行良好,可以对煤矿安全生产过程进行有效监控,在一定程度上预防煤矿事故的发生。The communication mode and communication range are constrained by the complexity environment of the coal mine. Wireless multimedia sensor network technology can be used to improve the supervision efficiency of the production and provide pow- erful information guidance for emergency rescue work. So a video sensor node whose main processor is S3C6410 is designed based on DISCOVER distributed video coding solution. The hardware block diagram and software flow chart of the node are presented. The test results show that the node runs well and can monitor the process of coal mine safety production effectively. To a certain extent, it can prevent the coal mine accidents.
