摘要
以矿井轨道运输监控系统为例,针对煤矿井下安全监控系统构建了2层RS-485体系结构,对RS-485芯片的外围配置进行了设计说明.并在此基础上,建立了RS-485总线的传输模型,针对RS-485总线的传输速率、负载数目与传输距离之间的关系进行了仿真分析.
Taking the mine track haulage supervision system for example,bi-layer RS-485 bus architecture for mine safety monitoring and control system is constructed,the peripheral circuit for RS-485 chip is designed. Meanwhile, communication mode for RS-485 bus is built,and simulation between communication velociload number and communication distance is made out.
