基于串口转WiFi的物联网终端远程控制实现方法

随着物联网技术的高速发展,对同一无线局域网内的设备进行控制时,存在传输距离短、可移动性差等缺点；针对此问题,提出了一种物联网终端远程控制的实现方法,采用串口转WiFi模块,通过Socket模式下的透传机制,传统的串口设备能够无线接入到互网络中基于MQTT消息传输协议的服务器上,完成数据的接收和发送,从而使终端设备突破无线通信距离的限制,达到数据交互和远程控制的目的；实验结果表明该方法正确、可靠,可广泛应用于智能家居、工业控制等领域。

Remote Control of Internet of Things Terminal Implementation Method Based on Serial to WiFi

With the rapid development of the Internet of things technology, control of devices in the same wireless local area network,there is a short transmission distance, poor mobility etc. To tackle this problem, here is one proposed remote control of Internet of things terminal implementation method, the serial to WiFi module, through the socket mode of transmission mechanism, the traditional serial port device can access the server based on the MQTT message transmission protocol in the Internet to complete the data sending and receiving, so that the terminal devices to break through the limitation of wireless communication distance, to achieve the purpose of remote data exchange and control. Experimental results show that the method is correct and reliable, and can be widely used in smart home, industrial control and other fields.
