摘要
针对现有矿井定位系统网络数据传输延时较大和定位精度不高的问题,提出了CAN总线传输网络和基于RSSI无线定位相结合的井下通信和定位方案。简要介绍整个网络体系结构,详细阐述了无线传输协议、基于CAN扩展帧的总线协议和基于RSSI定位原理及实现和自组网实现方案。实践证明,此网络体系结构具有低数据传输延时性和定位精确度较高的特点,提高了矿井定位系统的性能。
Due to the problems of high data transmission latency and low positioning accuracy of currently existing mine positioning system,this paper presents a new plan that combines CAN-bus based data transmission network and RSSI based wireless positioning system,and simply introduces its network architecture and wireless transmission protocol,bus protocol based on CAN extended frame,as well as the RSSI positioning principle and the complementation of Self-organizing networks.Practice shows that this network architecture works with low data transmission latency and features a high positioning accuracy,and significantly improves the performance of the mine positioning system.
