基于单片机的物联网传输数据高并发读写系统设计

目的为提高对物联网传输数据的高并发读写和控制能力,设计基于单片机的物联网传输数据高并发读写系统。方法构建数据信号均衡模型,根据物理节点资源消耗情况建立数据融合模型,计算信道的冲激响应值,利用随机序列扩频方法实现对信道的均衡控制。采用相邻帧补偿方法测量数据高并发读写参数,通过码元调制实现传输过程的误码补偿。在软件设计基础上,采用51单片机构建物联网传输数据高并发读写系统的硬件开发设计。结果实验结果表明,采用该方法进行物联网传输数据高并发读写的稳定性始终保持在0.8以上,且传输误码率最高仅为0.203%。结论设计的系统稳定性较好、传输误码率较低,有效提升了物联网传输数据高并发读写和控制能力。

Research and Monitoring of Metro Tunnel Deformation based on the Technology of the Internet of Things

After a long subway tunnel operators will produce cross-sectional deformation. Articles designed vehicle laser ranging device tbr continuous measurement of tunnel wall to test their defomaed state. The paper also describes the tunnel cross-section deltbrmation measurement method, contour titting principles and error analysis and networking technology for wireless data transmission methods. The detection system is designed to achieve a tunnel section of the structural safety testing and deformation that may occur timely disaster warning, the safe operation of the subway tunnel to provide effective protection.
