摘　　要：在目前的嵌入式终端数据远程传输控制系统中,对数据传输中的数据压缩率控制较差,在不同的网络情况下,不能实现动态调整,数据传输受网络情况影响较大。因此,提出物联网中嵌入式终端数据远程传输控制系统设计。软件方面设计嵌入式驱动程序和终端数据包传输程序,在数据包传输中,通过QoS(服务质量),根据网络情况来对数据包压缩率进行调整控制。硬件方面,终端选择C8051F310 MCU单片机,无线数据传输模块选择MC39I,同时为了保证终端可以连接物联网设计了SIM卡接口。为了验证设计的可行性,在物联网中引入数据,并使用所提系统与以前的系统进行对比实验。实验结果显示,该文设计系统在不同网络限流条件下,仍能保留良好的网络传输性能。In the current embedded terminal data remote transmission control system,the control of data compression rate in data transmission is poor,dynamic adjustment can not be realized in different network conditions,and data transmission is greatly affected by network conditions.Therefore,the design of embedded terminal data remote transmission control system in the Internet of Things is proposed.In terms of hardware,C8051F310 MCU is selected as the terminal,and MC39i is selected as the wireless data transmission module.Meanwhile,the SIM card interface is designed to ensure that the terminal can be connected to the Internet of Things.In the aspect of software,the embedded driver and the terminal data packet transmission program are designed.In the data packet transmission,the packet compression rate is adjusted and controlled according to QoS(quality of service)and the network situation.In order to verify the feasibility of the design,data is introduced into the Internet of Things,and the designed system was compared with the previous systems in a contrast experiment.The experimental results show that the designed system can still retain good network transmission performance under different network current⁃limiting conditions,which proves the feasibility of the system.
