Design and Implementation of Multi-Source Monitoring System Based on Embedded Platform
In the context of the Electric Internet of Things and transparent grids,substation monitoring has the characteristics of large monitoring area and many target subjects,therefore,a low-cost,compact multi-source monitoring system is urgently needed.A multi-source information monitoring system based on embedded platform is developed for the needs of substation scenarios,which integrates the sensors such as OV2640 and MLX90640 to realize monitoring data collection.Aiming at the bandwidth pressure and computing pressure brought by massive monitoring data,the node chip ESP32 is used to realize the edge processing of information.In the part of infrared image processing,the mapping relationship between temperature values and RGB values is established through the color table to visualize the temperature information.According to the characteristics of diversified inspection methods of substations,the monitoring system constructed by wireless Mesh routing has the advantages of dynamic link adjustment and scalable coverage.Finally,the feasibility of the system is proved by experiments.
