This invention relates to the field of IoT communication technology for lubrication equipment, and discloses a method and system for switching control of IoT edge communication modes for lubrication equipment. Edge nodes collect real-time communication environment data, equipment operation data, and business data requirements. Based on this multi-dimensional data, a multi-dimensional switching decision model is constructed. Physical dimension differences are eliminated through standardization processing, and a comprehensive score for each supported communication mode is dynamically calculated. Dynamic monitoring is performed based on the comprehensive score and trigger conditions including preset difference parameters. When the conditions are met, the target communication mode is selected and seamless switching is performed. When a device fault is detected, a fault adaptation evaluation value is calculated, and a forced switch to a low-latency communication link is initiated. This invention achieves deep coupling between the underlying communication state and mechanical operating conditions, thereby possessing edge emergency takeover and overflow prevention buffering capabilities under network-wide interruption, ensuring equipment operational safety.
