【摘要】 矿井的安全生产至关重要,为保证安全生产,防止矿井灾难的发生,需要对矿井中各项环境和设备数据进行监控。传统的监控系统中,由于井下各种数据采集的多样性和存在各种形式的干扰信号,监控节点虽然能够有效获取数据,但是井下生产的特殊性严重影响数据的有效传输。本文通过对井下环境以及井下数据通信需求的分析,设计了基于ZigBee网络技术的井下安全监控系统,将监控系统的构成分为采集监控数据的定位节点和终端节点,完成监控数据传输的参考节点,执行控制功能的监控主机。论文给出了主要功能实现过程中的软件流程设计论文所设计的监控系统不仅能够提供安全监控过程中监控数据的采集和传输,监控节点还能够随着井下采掘巷道的使用状况而进行位置调整,同时监控系统还能够针对移动的监控节点进行物理地址的定位。基于ZigBee技术的网络具有低成本、低功耗、节点容量大、结构简单的特点。而且网络的后期维护也比较容易,因此能够广泛的应用于监控系统中。本文所设计的系统功能部分经过实际组网测试,基本达到设计要求,仍需要进一步完善和改进。更多还原

【Abstract】 Mine safety is essential, in order to ensure safety and prevent mine disasters, it’s need to monitor the data of the mine. In traditional monitoring system, due to the diversity of underground variety of data acquisition and the presence of various forms of signal interference, even though it can effectively control access to data nodes, but the special nature of underground production influences the effective transfer of data. Based on the analysis of the environment and the underground data communication needs, this thesis designs mine safety monitoring system based on ZigBee technology, and breaks down the monitoring system into monitoring host, reference nodes, positioning nodes and terminals. In addition, this thesis gives the design process.This monitoring system is designed not only to provide data collection and transmission, control node can also adjust along with the service condition of the underground mining tunnel, while the monitoring system also position the physical address of the moving nodes. Network based on ZigBee technology, has many advantages, such as low cost, low power, large capacity, simple structure, and easier to maintain, so that monitoring systems can be widely used.Part of the designed system functions have been actually tested underground, there are also some features still in the theoretical study and simulation stage, which still needs further refinement and improvement.更多还原
