该文在大量测试实验和理论分析的基础上，研究电磁波在楼内公共烟道的传输问题，分析公共烟道环境的特殊性以及影响电磁波传输损耗的因素。提出一种适用于楼宇集中净化物联网系统的基于SX1278的无线传输方案。该方案采用直接序列扩频调制来提高系统的抗干扰性能，采用截断二进制指数退避算法作为重传机制来解决节点信号冲突碰撞问题。通过在基站端采用时间片轮转调度，来保证计数的同步性和实时性。集成测试和实地测试结果表明，该方案很好地解决了烟道内无线信号的稳定传输问题，且丢包率和误码率较低，系统可靠性好。-On the

本设计系统地设计了双直流电动机调速的实时同步调速控制系统。经过多次的运行与检测，实践证明该电路工作稳定，显示清晰。其有以下特点：①调速性能好。电动机在一定负载的条件下，根据需要，能人为地改变电动机的转速。直流电动机可以在负载条件下，实现均匀、平滑的无级调速，而且调速范围较宽。②能实现双电机的同步无误差控制。在外负载改变第一个电机的转速时,另外一个电机可以跟随第一个电机的转速，实现同步无误差控制。采用全汇编语言设计，值得参考。-The design of the system design
