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.
