摘要: 实现基于Mesh网络的远程控制系统。距离数十公里也可以通过观看操作中心监控图像来操纵设备,并且视频画面不卡顿,操作流畅没有误动作,系统体验友好。从各个子系统的原理和设计入手,完成Mesh基站的网络架构、通信协议设计和软硬件设计,最终实现远程控制系统。对整个远程控制系统的实现进行详细分析,通过对通信环境的测试,得出第一手的数据,计算出丢包率、延时、抖动等重要参数。保证整个系统的QoS接近实际需求。以控制铲运机为例,但是不局限于此,可用于其他远程控制类设备。

Abstract: A remote control system based on the Mesh network was accomplished. In the control center where tens of kilometers from the device, people can still control the device correctly with smoothly playing monitoring image and videos. From the principle of every single system, it was finally accomplished by designing the Mesh network, the communication protocol, the hardware and the software. After that, the whole system was analyzed in detail and its firsthand data is collected after the communication test. The packet loss rate, delay, jitter were calculated to guarantee the QoS of the system. The remote control system is installed to the model of scraper, but it can be used to any device needed to be controlled far away.
