摘要
设计了一种基于LoRa协议的多信道智能防溜系统,实现了对智能铁鞋业务数据的实时、可靠上传。通过无线数据终端构建多级、多信道通信网络、业务数据及心跳数据以多种信道方式传输,数据有序上传,对不同来源、优先级数据打包发送,优先发送智能铁鞋溜逸数据帧。该数据传输方法实现了智能铁鞋数据的快速、可靠传输,有利于提高对站场智能铁鞋的管理效率,具有很高的理论意义和实用价值。
Based on LoRa protocol a multi-channel intelligent anti-slip system is realized,which can complete real-time and reliable uploading business data of the intelligent iron shoes.The multi-level and multi-channel communication network is constructed by wireless data terminals.The business data and heartbeat data of the terminals are transmitted in various channels,and the data is uploaded orderly.The data from different sources and priorities are packaged and sent,and the intelligent iron shoe slip data frame is sent firstly.The data transmission method can realize fast and reliable transmission of intelligent iron shoes data,which is beneficial to improve the management efficiency of intelligent iron shoes in station,and has high theoretical significance and practical value.
