摘要
针对密闭环境内数据通信困难、传输速率慢的问题,本文设计组建了适应型无线通信网框架,通过LoRa通信技术铺设大量数据传输通道,加强数据交互能力;通过架设通信网线路,使各通信设备联系起来,避免由于数据过大造成的传输堵塞;采用循环冗余(CRC)校验码算法将待传输数据演化为二进制序列,通过校验码的形式进行通信,使传输速率更快。最后进行实验分析,通过计算机生成采集数据误差和通信数据误差,证明了组建的无线通信网的可行性。
In order to solve the problem of data communication difficulty and slow transmission speed in closed environment.In this paper,an adaptive wireless communication network framework is designed and established,in which a large number of data transmission channels are laid through LoRa communication technology to enhance the ability of data interaction,in order to avoid the transmission jam caused by the large data,the cyclic redundancy(CRC)check code algorithm is adopted to deal with the evolution of the transmitted data into binary sequence,and the transmission rate is faster through the form of the check code.Finally,the experiment analysis is carried out,and the data acquisition error and communication data error generated by computer are used to show the feasibility of the wireless communication network.
