物联网设备远程控制技术研究与改进

The Research and Improvement oF IoT Equipment Remote Control Technology

对传统物联网设备远程控制技术进行测试和分析,提出一种改进的物联网设备远程控制方法,旨在解决因为通信延迟或错误导致的用户终端状态更新慢、数据过期、界面异常或卡机等影响人机交互流畅性的问题。在用户终端创建虚拟设备模块,该模块与网络应用服务器连接,用于接收用户指令、转发控制消息、同步和校验设备终端状态等工作;在设备终端联网模块上增加指令抵达消息反馈机制,在接收到有虚拟设备发送的控制指令时先立即以轻量数据包原路返回,然后再把控制指令转发给下层电器模块进行处理。实验结果表明:这种改进的远程交互方法和装置,减轻了应用服务器与设备终端的数据处理压力、能够保证用户终端与设备终端状态的匹配、明显提升了用户终端指令响应速度,操作过程流畅、敏捷、正确。

Based on the test of the remote control technology of the traditional Io T equipment and research on it, a new method isproposed to resolve the human-machine interaction fluency problems such as status update slow, data expired, UI exception or sys-tem halted, that caused by communication delay or error. A virtual device module is created on the user terminal, which connectedwith the network application server. It can send and receive command messages, and forwardly synchronize and check the equip-ment running state. A message feedback mechanism is created in network module of the equipment terminal, when it received acontrol message, It will be the first to return data with a lightweight data packet and then forwarded to the next layer of electricalmodule. The experimental result shows that the improved method and device can reduce the processing pressure, guarantee the da-ta correctness of the equipment and user terminal, It really improves the fluency of human-machine interaction.
