【摘要】针对煤矿井下现有数据传输系统存在数据传输距离有限、节点部署不便、传感器地址有限、数据传输不及时等问题,设计了一种基于6LowPAN的煤矿井下数据传输系统。该系统采用以太网与6LowPAN协议组合,在数据采集节点预留SPI、RS485等接口实现传感器数据的采集。数据采集节点为无线网络节点,可通过路由系统选取合适的路由路径将传感器数据发送至数据汇聚节点;汇聚节点与边界路由构建有线连接,将数据经以太网上传至地面服务器,从而实现数据的稳定可靠传输。测试结果表明,该系统无论在传输时延、丢包率,还是吞吐量方面都明显优于传统的数据传输系统,可高效、可靠传输煤矿井下数据,具有良好的实时性、较高的通信速率和稳定性。
【Abstract】In view of the problems of the existing data transmission system in coal mine underground, such as limited data transmission distance, inconvenient node deployment, limited sensor address and delayed data transmission, a data transmission system in coal mine underground based on 6LowPAN was designed. The system adopts combination with Ethernet and 6LowPAN protocol, and SPI, RS485 and other interfaces are reserved in data acquisition nodes to realize sensor data acquisition. Data acquisition nodes are wireless network nodes and can effectively select appropriate routing paths through the routing system to send sensor data to the data sink nodes. Wired connections can be built between the sink nodes and the boundary routes, and data can be uploaded to the ground server via Ethernet to achieve stable and reliable data transmission. The test results show that the system is obviously superior to the traditional data transmission system in terms of transmission delay, packet loss rate and throughput, and can efficiently and reliably transmit underground data of coal mine with good real-time performance, high communication rate and stability.
