The traditional star-coupled and single-gateway network has poor robustness and limited function.In the paper,an intelligent monitoring and verification platform is designed based on LoRa AD-hoc network,which chooses STM32 as the core controller.The hardware of the platform includes intelligent sensing terminal and dual channel gateway,and the software includes LoRa communication protocol and link selection strategy in MAC layer.The platform can realize dual-network access of terminal nodes,dynamic variation of network structure and functional reconstruction of system application,which can effectively improve the robustness and processing capability of the IoT system.
