The invention relates to a power Internet of Things information interaction process analysis method and system considering resource constraints. The method comprises the steps of obtaining an information interaction process meeting a preset power Internet of Things service target in an information interaction process of a power Internet of Things service; determining an information interaction process satisfying a given resource constraint in the information interaction process satisfying the preset power Internet of Things service target. According to the technical scheme provided by the invention, for a power application scene, whether the structure and the performance of the power Internet of Things information interaction process meet the requirements of a service target or not can beverified, and the normativity and the reliability of the power Internet of Things application are ensured.
