Fuente: Wipo "IOT" The invention discloses a method for sharing an intelligent engine by multiple devices, and the method comprises the steps: detecting whether an IoT device is provided with an intelligent engine whena system detects that the IoT device is connected, reading and storing the type of the intelligent engine in the corresponding IoT device when the IoT device is provided with the intelligent engine, and obtaining the online state of each connected IoT device; after any IoT equipment in the system receives a search instruction of a user, sending the search instruction to a system cloud server for instruction type identification of the search instruction, and sending the received search instruction to an online first IoT device where the intelligent engine corresponding to the IoT device is located by the IoT device according to the corresponding relation between the instruction type of the search instruction and the type of the intelligent engine; and inputting the received search instruction in an intelligent engine of the first IoT equipment for processing by the first IoT device. According to the method and the device, the advantages of the intelligent engines in multiple devices canbe complementary, and the user instruction accuracy is optimized.
