Fuente: Wipo "IOT" The present invention relates to a fast data processing system using IoT device interworking in edge computing, which interworks with an IoT device based on a configuration, processes fast data requiring immediate response among stream data generated from a plurality of IoT devices at an edge in real time, and transmits the remaining data to a cloud server. The present invention comprises: a cloud server analyzing stream data collected from a plurality of IoT devices for building an IoT environment; and an edge gateway having an IoT gateway for collecting stream data generated from the IoT device and an edge server for analyzing and processing stream data collected from the IoT gateway. The IoT gateway includes a real-time dynamic configuration management and interworking function for the IoT device, a collection function of real-time stream data, and an immediate response function driving the IoT device according to an immediate response request. The edge server requests an immediate response to the IoT gateway for fast data among the stream data generated from the IoT device received from the IoT gateway, and delivers the remaining data not requiring an immediate response to the cloud server.
